Chapter 1

The clock was ticking. Literally and figuratively, and Cas hated it. He sat on one of those uncomfortable plastic chairs in the clinic, waiting for his appointment. The hospital smelled like disinfectant and other things that made his stomach churn. He just wanted to leave.

A quick look at his watch told him that he had already waited for thirty minutes, and he hated that he was missing so much work for this.

“Mr. Novak?” A nurse called him. 

He looked up, nose in his air. She was a beta, and he tried to fixate on her faint smell, to get the disinfectant out of his nose. It didn’t work. “Yes.” Cas stood up and followed her, relieved that it was finally his turn. He really wanted to get this over with.

He sat down on a brown leather chair in front of a dark wooden desk that was stacked with papers and files. The doctor arrived a second later. An Omega like Cas, who looked very friendly. The doctor shook Cas’s hand, his grip strong, and Cas couldn’t help the smile. “Professor Novak, I’m Dr. Aaron Bass.”

His heart beat faster and he felt nervous when the doctor opened his file. “There’s good news and there’s bad news, Professor. Good news is: all of your organs are healthy and your heart is in great shape. I can see that you’re exercising regularly and it’s paying off.”

Cas nodded grimly. “What is the bad news?”

Dr. Bass sighed, his eyes flying over the file. “You were right about your assumption. Your fertility is dropping and that is why your heats are getting worse. I would estimate another year until you won’t be able to get pregnant anymore. I can suggest having a minor procedure, taking out some of the eggs and freezing them, but the success rate later is… it’s not good.”

Cas frowned and shook his head. “I don’t… I don’t want children. My job is everything to me.” He sighed and rolled his eyes. “My biology is the only reason having children is on my mind, but I know it’s not me who wants them, only my hormones.”

Dr. Bass nodded in sympathy. “I know what you mean. The problem is that your heats will get worse. And I hate to say it… but they probably will occur a lot more often from now on. You might want to take a sick leave from work.”

“Is there nothing I can do? Nothing I can take? Suppressors?” Cas asked, dreading the answer. This could not be happening. He hated his heats. To know that they would get worse and more frequent was a nightmare.

The doctor shook his head. “Suppressors won’t work at this stage. I’m sorry. There is only one thing that will ease this transition period until you lose your fertility and the heats stop.” He grabbed a flyer and handed it to Cas.

When Cas looked at it he swallowed dryly. It was an ad for an alpha service. “No… you can’t be serious.”

Dr. Bass sighed, giving him a serious look. “We work with this agency a lot. They are professional, and all their alphas are clean and chipped. Professor, I wouldn’t recommend this if the situation wasn’t that bleak. The only thing strong enough to balance out your hormones is an alpha. You would need to scent him on the regular and if the heats are getting to be too much, I would recommend using an alpha for those times as well.”

Cas just stared at him. This wasn’t happening. He couldn't imagine himself with an alpha. 

When he didn’t react, the doctor filled out a prescription and handed it to Cas. “Call the agency and make an appointment. Here is the prescription for what the alpha needs to provide. If it helps… Many of our patients have used them at some point, and they were all very satisfied with the agency. You don’t need to suffer through this. Please, use this service.”

Cas stared at the prescription and the flyer before he nodded softly. “I’ll think about it. Thank you, doctor.”

…. :::: :::: ….

Back home Cas immediately knocked on his neighbor’s door, who also happened to be his best friend, and ex-boyfriend. Sadly, it hadn’t worked out between them, but thankfully it hadn’t impacted their close relationship at all. Inias was an Omega like Cas, and they had known each other since college. Their personalities couldn’t have been more different. Inias was adventurous, often trying out new things, whereas Cas loved peace and quiet. The dynamic worked beautifully for their friendship, but in their relationship, it had been a disaster.

When Inias opened the door he was wearing an apron, sporting some flour on the tip of his nose. 

Cas couldn’t stop the laugh. “Are you baking?”

"What gave it away?" Inias asked sarcastically as he stepped aside for Cas to enter.

"I was just surprised," he explained as he walked into the apartment. Everything smelled sweet and like lemons. "I've never seen you bake before."

Inias chuckled. "I promised to help with the bake sale. And that was a terrible mistake."

"It smells very good though," Cas said as he sat down at Inias’s breakfast nook. "Am I disturbing you?" he asked, hoping that Inias would have some time for him. He really needed his best friend right now.

"No, just let me grab the lemon squares from the oven," Inias said as he busied himself in the kitchen, pulling out a clear glass dish that smelled divine. He dropped it on the top of the stove and turned back to Cas, taking off his apron. "Can I get you anything?"

Cas sighed. "A beer if you have one." He closed his eyes and smelled the air again. "You’ve been holding out on me."

Inias rolled his eyes. "I really wasn't. This…" he waved at all the baking supplies in the sink, "... is never happening again."

Cas gave him a puppy eyed look. "Why? You’re obviously amazing at it?" And he certainly wouldn't mind a fresh baked pie from time to time.

Inias handed Cas a beer, lips pursed in amusement. "You didn't come here to talk about my baking skills."

Sometimes it wasn't an advantage that Inias knew him so well. He sighed, rubbing his hands over his forehead before he confessed, "I just got back from my appointment at the clinic. About the results of my annual health check up."

The expression on Inias's face was rife with concern. "Are you okay?"

Cas shook his head. "The doctor said I'm getting infertile and until it finally happens, my heats will get worse and more frequent. He said..." Ugh, this was so embarrassing... "He wrote me a prescription for an alpha service."

Inias's eyebrows shot up. "It's that bad?"

Cas rubbed the back of his neck. "Yeah. I mean... he wouldn't have prescribed it, if it wasn't necessary. But..." He groaned and looked at the ceiling. "I really don't want to do this. I feel dirty just thinking about it." 

He couldn’t help but grimace. "I know you like to try out new things... have you ever had sex with an alpha? Or do you know anyone who has?"

Inias nodded as he sat down on the stool next to Cas. "Once. I was at a conference and had forgotten my suppressors. It got bad, so I went to a nearby alpha service for relief."

Cas scrunched up his nose. "Oh, really... Um, how was it?"

Inias shrugged. "It… definitely scratched an itch. I don't know. He was… aggressive, but then, that's their nature, isn't it?"

Cas really hated hearing that. "Fuck... I..." He pressed his knuckles into his legs, before he grabbed the beer and took a few huge drafts. "I have to confess I'm worried about that. What if I do this and he does something against my will? I mean, I know they are all chipped and if they do anything they immediately go to prison... but by then it's too late, you know?"

Inias nodded. "True, but these services are usually up to code. Especially the ones recommended by physicians. It's still a business that needs to keep the client happy."

Cas knew that, but he was still nervous. "Um, Nias. Would you be there when I meet him for the first time?"

"Of course." Inias patted Cas's hand, then flashed him a small smirk. "One plus I can tell you, a real knot is so much better than a toy."

Cas flashed him a miserable look. "I hate those toys... Remember when we spent our heat together with those things?" 

Inias smiled, a soft laugh escaping his lips. "Hey, we'd never tried them before. I've definitely learned some things over the years."

Cas gave him a soft smile. "I really hate our biology," he murmured after a while. "That we need an alpha for this stuff and can't do it with another Omega or even a Beta. It's just unfair."

"It does seem pretty fucked up." Inias took a swig of his beer. "I think some services can offer submissive alphas."

Cas raised an eyebrow. "That's a thing?" He had never heard of a submissive alpha before. That would be a lot better for Cas because the last thing he wanted to do was submit himself to an alpha. He was good at suppressing the submissive urges of his Omega. 

Inias nodded. "I think so. You should call the service and ask."

"I will." Cas replied after a moment. He felt a lot better now. Especially knowing that Inias would be by his side when he met whatever alpha he would get. "Thanks, Nias." He gave him a smile before he looked longingly at the lemon squares. "What do I need to do to talk you into giving me one of those?"

That was met with a smirk. “Promise me you’ll use that toy before you go to sleep. Give it another shot.”

Cas pressed his legs together, flashing Nias a bitch face. "Stop making me think of sex." The last thing he wanted was to get horny. He was way too easily triggered at the moment. Fucking hormones. He felt like a stupid teenager. Cas sighed when his thoughts wandered to the toy that Inias bought him when they were still together. 

It wasn’t his favorite. Way too big for him and Cas usually didn’t have the patience to work himself open. “Okay, just because I really want to taste what you made there. You always use my sweet tooth against me.”

“Damn right.” Inias got up and grabbed a small tupperware container. He dropped two squares into a paper towel and sprinkled some powdered sugar on them. After he closed the lid, Inias stepped in front of Cas and held out the container. “One for before, and a reward for after if you promise to properly prep yourself.”

"You know me too well," Cas growled as he took the container and leaned over to kiss his cheek. "I'll get out of your hair, but I'll text you as soon as I get that appointment set up. I really hope it will be worth the trouble."

Inias gently patted Cas’s cheek. “Hey, at least it’ll be temporary. There’s an expiration date.”

"Yeah." He rolled his eyes. "I don't know if it was just my imagination, but I think the doctor judged me a little for not wanting any children. I’ll be glad when this is all over and I'm not a slave to my hormones anymore."

“We’re Omegas, Cas. We must have babies, it’s in our genes!” Inias let out a dramatic sigh and looked at his messy kitchen. “See? Even I’m not immune to my need to nest.”

Cas wrapped his arms around Inias and pulled him into a hug from behind, resting his chin on his shoulder. "This is the worst nest I have ever seen, Nias." He chuckled before ruffling Inias’s hair and drawing back. "The doctor said one more year. And then I'll be free."

Inias smiled. “A year is nothing. You can do this.”

"Thanks for the vote of confidence." Cas chuckled before he nodded at him. "Good luck with the bake sale. If you have left overs you know where to find me."

Inias barked out a laugh. “Go home, Castiel.”

Cas chuckled and left Inias’s place, crossing the hallway to get to his own apartment. When he closed the door, Cas sighed, trying to calm down his beating heart. 

Booting up his laptop was the first thing he did before opening the container and taking a bite from the lemon square. Fuck, they were heavenly and he knew he was eating out of frustration and nervousness, but he couldn't help it. He needed some nutrition for his nerves as he opened the website on the flyer the doctor had given him. Everything looked very professional and he sighed before he picked up the phone, getting it over with. It was a prescription... How bad could it go?

…. :::: :::: ….

Dean was buttoning up his shirt, a fake smile painted on his face as the Omega laid on the bed, sated and blissed out. He was a weaselly looking Omega, with a sharp nose and even sharper tongue. 

“There’s a little extra on the nightstand for you,” the guy said with a dismissive wave of the hand.

A quick turn of the head and Dean could see a couple hundred dollar bills. 

“We aren’t allowed to take tips,” he said as he pulled on his belt. 

Some Omegas did this as a flex, a reminder of what Dean was, and what his use was as an alpha. 

Weasel sat up, flashing Dean a lecherous smile. “I won’t tell if you don’t.”

That was another trick Omegas would use. Report you for taking the tip to get their money back. Any alpha who took gratuity from a client would be punished, the degree of punishment varying based on the offense. 

And anyway, it wasn’t like he could just wander to a store and buy something on a whim. The closest to freedom most alphas could get was the walk to and from a client’s house. The lucky ones would get rented, or even bought, and get to spend their days as a live-in sex toy. It wasn’t perfect, but getting rented or bought sure beat sharing a cramped eight-by-eight space with four other alphas. 

Dean was a submissive alpha though. There weren't many of his kind, and not a lot of demand for his exact type of service. More often than not, when he got work, it was an experimental curiosity being explored. A kink. 

And Dean had made peace with that years ago. 

“I appreciate the gesture, but I have to say no. You have my agency’s number if you require my services again,” Dean said in an almost robotic tone. Sales pitch, check.

The Omega sat up, expression saddened. “Did you feel anything?”

Dean should have left half-dressed. He hated when Omegas asked this question. Not all of them, but too many had clearly watched chick-flicks about winning the affection of a sex worker. With another false smile, Dean recited, “Of course.”

This Omega didn’t need to know that all Dean felt was the pleasant sensation of knotting a tight, slick hole. 

Expression now relieved, the Omega looked Dean up and down, lips curled in a lascivious smirk. “Then I’ll definitely call again.”

Dean’s cheeks were beginning to ache from the force of holding his smile. With a nod, Dean grabbed the doorknob and escaped, almost leaving his leather jacket draped across the back of the couch he had been so rushed.

When Dean got outside, he pulled the jacket over his torso just as a sharp wind rushed him. And despite the severe chill, Dean had no intention of speeding up the walk back. It wasn’t like he was heading to a warm room, a hot meal, and kind eyes.

Dean sighed and zipped up his jacket, head bent forward against the force of the wind as he counted the steps back to what his life had turned out to become. Having been born to an Omega and Beta couple, there had been no expectation for Dean to present as an alpha.

He was only eleven, and suddenly his relationship with his family shifted. Dean could smell fear on his parents, and there was a significant change in their behavior toward Dean. Sammy, his little brother, had been the only one to treat him the same. After two months, an older man arrived on their doorstep with a duffel for Dean to pack. 

Bobby Singer. He ran a “camp” for alphas, training them for one of the two positions in society they were allotted. Manual labor or sex work. Dean didn’t get a choice, and if he did, he wasn’t sure he would have chosen manual labor. At least with his current position, he got regular sexual gratification. 

The wind chill caused Dean’s teeth to chatter. “Shit,” he cursed and hated that he picked up his pace. So much for the extra time for a little respite.

…. :::: :::: ….

Cas was nervous. He was glad that Inias was sitting next to him, at his side in all of this. He really didn't want to be alone the first time meeting the alpha the agency was sending. They had described him as submissive, but who knew what that meant in relation to an alpha? 

The first meeting was only to get to know him. Cas mostly needed him for scenting and cuddling, to stabilize his hormones. He hadn't decided yet if he would use him during his heat. It would depend on how this first meeting went.

When there was a knock on his door, it felt like his heart was plunging to his feet. "Fuck," he cursed, giving Inias a pained look. "What if he smells horrible?"

Inias rolled his eyes. “Then exchange him. Come on. I’m dying to see the guy.”

Cas got up and walked over to the door with a heavy beating heart. His hand trembled when he carefully opened it.

The moment he looked up, he was met with stunning green eyes, a really handsome freckled face, and a scent that was absolutely mouthwatering. Like a million times better than when Inias had baked. 

He swallowed dryly. "Um, h–hello."

Dark blond lashes blinked as a smile curled his lips. “Castiel?”

Cas nodded. "You, um, are Dean? From the, um, alpha service?" He had no idea why he was stuttering. Cas felt like an idiot, but the man in front of him made him dizzy. 

Dean nodded, leaning his arm against the open doorway. “Can I come in?”

“Um, yes! Of course.” Cas quickly stepped aside, trying not to stare as the alpha walked into his apartment. He pointed to Inias. “This is Inias. I asked him to be here for our first meeting. Getting to know you. Please, um, sit.”

Dean shrugged off his leather jacket, revealing a pair of toned arms hugged by a tight t-shirt. His muscles rippled with the movement of draping the jacket over the back of the couch. He reached out his hand in offer to Inias. “Hi.”

Inias took his hand, and Cas knew what the expression on his face meant. He liked what he saw. “You must constantly be in demand.”

Cas's Omega frizzled inside of him, reacting possessively in that moment. He rolled his eyes. Stupid hormones. Inias wasn't competition. 

He took a deep breath, trying to clear his head as he sat next to his best friend. He sat very close, because he needed Inias’s scent to distract him from Dean. 

The last thing he wanted was to get over excited. It would be pretty embarrassing if Dean smelled it.

He leaned against Inias’s shoulder for a moment before he said, "I don't know how much the agency briefed you on my case."

Dean moved to sit in the chair across from them. “Standard SC case to stave off hormones, yeah?” He leaned forward, elbows braced on his knees. “They didn’t mention it was for a couple.”

“We’re n–”

Cas kicked Inias’s shin, giving him an imploring look. He would feel so much safer if the alpha believed that. "Um, yeah... That's not a problem, right?"

Dean shook his head. “No, but the rate is per Omega, so no two-for-one deal.”

Cas quickly held up his hands. "Oh, no, no. It will just be you and me. Inias doesn't have any medical problems. I just wanted to make sure, he approves of this… you. He is a lot better at judging character."

With that, Dean moved to sit back, bracing his arms on the rests as he crossed his leg, ankle to knee. “An SC is purely transactional, no inappropriate contact. You have nothing to worry about.”

Cas swallowed dryly, exchanging a look with Inias. He knew he had to apologize to him for at least a month after pulling this. "If this goes well... I might also need you for my... um, heat."

Dean flashed him an understanding smile. “Do you have any questions?”

Cas nodded, starting to feel a lot more at ease with Dean. His voice was soothing, professional. He wasn't intimidating at all. At least for now. "Yes, the agency said you would be submissive. That is very important to me. If I choose you, to help me, I won't submit to you. I will be the one in control."

“That’s why they sent me. If you choose me for your heat, I will submit to your requests.”

Inias waggled his eyebrows at Cas and gave him a small nod; there wasn’t enough movement for Dean to have noticed. 

Cas grabbed Inias by the wrist. "Can I offer you anything to drink? I have to talk to my, um, boyfriend… in the kitchen."

“Uh, anything sweet, if you have it.” Dean said.

Cas raised his eyebrow. It was the first time he couldn't help a smile. "Yeah, okay." He pulled Inias up with him, dragging him to the kitchen before he grabbed a Coke from the fridge and went back to quickly hand it to Dean. Being so close again, he could smell Dean and fuck... he was really liking that scent. "I'll be right back," he said with another shy smile before he practically fled back to the kitchen.

Being alone with Inias, he gave him a sheepish smile. "Sorry about that. I swear, I’ll make it up to you. But um, what do you think? Honestly."

Inias whistled. “I think you should definitely use him for your heat. Damn,” he said as he poked his head out through the doorway, likely to look at the alpha. 

Cas rolled his eyes. "Yeah, helpful, Nias. I have eyes in my head. I can see he is very attractive and... fuck, I don't know how he smells to you, but... it's so nice." He shook his head, clearing his mind. "What I mean to ask is, do you think I'll be... safe with him?"

Inias hummed as he turned back to face Cas. “Don’t get me started on that smell. He seems pretty nice to me. The alpha I hired was… not that well spoken. Of course, it wasn’t one of those nice, medical agencies. He also wasn’t submissive...”

"So you think I should do it?" Cas asked softly. Just to make sure. He hadn't been lying before. Inias was by far better at judging character than Cas.

“Your call, Cas, but I honestly doubt you’ll find better.”

Cas nodded slowly. Inias was right. It was this alpha or no one. "Alright... I think I'm ready to be alone with him. If you don't hear from me after one hour..." Cas reached for Inias's hand before he sighed over dramatically. "It was nice being your boyfriend."

Inias rolled his eyes and took Cas’s hand with a squeeze. “My guess is if I don’t hear from you in an hour, it’s because you’re riding that knot.” He hummed again, expression a little dazed. “I bet he has a big one.”

Cas immediately pictured it and he knew his best friend had done it on purpose. He could feel the heat at his hole. "Ugh, Nias, you're an asshat." He groaned as he pushed him towards the door. "Time for you to leave."

“Oh, yeah,” Inias purred, waving to Dean as he disappeared through the living room and front door.

Suddenly they were alone. And Cas's nervousness was back. He gave Dean a shy smile before he sat down on the couch again. 

Clearing his throat, he said, "So um, do you want to come and sit next to me?"

Dean put the soda on the coffee table, after grabbing a coaster. He made his way to the couch, sitting close enough that their legs were touching. “This is your first time.” It wasn’t a question.

Cas nodded softly. "Um, yeah. I've never been with an alpha before." He hated how much just saying the word excited something primal in him. "Um, what... How do we do this? Can I just..." He looked up at the alpha's green eyes. "Lean against you and scent your neck?"

Dean shifted back, bracing his arm across the back of the couch. “Go for it.”

Cas pulled one leg up on the couch, creating more distance between them before he hesitantly bent forward, closer to the alpha's throat. He took a careful sniff and his nose got flooded with the most alluring scent he had ever experienced. A soft gasp fell from his lips. "You smell really nice," he breathed out.

“We must be compatible.”

Cas raised his eyebrow at Dean. "Do I smell nice for you, too?"

“I could smell you from outside,” he said simply.

Fuck, Cas knew alphas had an extreme heightened sense of smell. Even more so than Omegas. He wondered if Dean could smell the arousal starting to pool in between his legs. He drew closer, his nose accidently bumping against Dean's neck. "Sorry," he mumbled, already feeling drunk from the scent. He had no idea it could feel like that. His whole body was relaxing, practically melting. He hadn't been aware of how much tension he had been holding in. "My, um, doctor said... my heats will be more frequent... more intense. I think... I'm open to trying this with you, booking you when it's time for that. Probably in a week."

Dean nodded. “Heats are charged by the hour, unless you rent me for a specific length of days. “

Cas sighed and nodded. "Actually my insurance is paying for it. I think they cover the whole three days."

“That’s fortunate,” he said, his voice smooth and inviting. “What have you done to combat your heat in the past?”

Cas could feel his head dropping forward, closer to Dean's scent. "Um... I... I mostly suffer through it and um, hope it's over quickly. Inias got me this... um, toy... but it's too big and I get impatient easily." It was so hard to concentrate with Dean’s scent being so close.

“I can help with that when it’s time for your heat,” Dean said, his voice somehow deeper.

"Um, yeah? What would you do?" Cas asked with a soft gasp before he could stop himself. Talking about this wasn't really improving the situation between his legs. He could feel himself getting wet and it was so embarrassing, because he knew the alpha was able to smell it.

Dean hummed. “I would use your slick to get you sloppy, build up your tolerance, stretch you until you’re able to take my knot.”

Oh my... 

Cas closed his eyes, biting down on his lower lip. His underwear was wet now and he couldn't believe Dean had done that with only a few words. He looked up at him, knowing he was blushing. This wasn't going in the direction he had wanted, and although all his hormones were screaming for more, he had enough willpower to shut those voices down. "We also need to talk... about contraception. My hormonal ones aren't working anymore... due to this, um, medical problem."

“Our agency performs vasectomies on all alphas.” Dean said, his nostrils flaring as he took a deep inhale. “So, you won’t get impregnated, no matter how much of my seed I fill you with.”

Cas felt incredibly relieved by that. "Oh... okay. So you're different from other agencies. I've heard there are also ones for, um, breeding." Fuck, he was getting so wet. The images Dean was conjuring in his mind... he really wanted to get out of his pants.

Dean nodded. "Yes, if you are ever looking to reproduce, our agency can connect you with a reputable breeder."

"Oh, no." Cas quickly shook his head. "Having a kid is the last thing I want." He chuckled softly. "I know it's not very Omega of me, but I'm really not interested in that. No matter what my biology wants."

Dean's eyebrows shot up for a brief moment. "I understand. It's why I was glad I was chosen to work for this particular agency."

"You didn't want to have kids either?" He was really surprised by that. He always thought breeding was the only thing on an alpha's mind.

"No. There's enough abandoned pups out there." Dean shifted slightly, causing his leg to rub against Cas's. 

Cas closed his eyes for a moment and nodded softly. Dean felt warm and inviting, his scent luring him in like a gravitational force. "Um, can I... um, lean against your chest to really scent you, or is that... um, too intimate?"

"That's allowed, but if it turns sexual, it's an extra charge," he said as he grabbed the hem of his t-shirt. "Would you like me to remove my shirt?"

Cas nodded quickly. "Yes, please and I know, um... that you probably smell me. But I really don't want to have sex today. That will be only for when I really need it."

Dean nodded, pulling off his shirt and draping it over the couch. "You smell like you already do need it," he said with a sweet smile. 

Cas scoffed and nodded before he grabbed his own shirt, pulling it off. He was already too hot and uncomfortable in his clothes. His underwear was sticking to him, and it felt disgusting. But he feared getting out of his pants would cross a line. "This is nothing compared to my heat," he growled softly as he shifted on the couch, leaning sideways against Dean's chest before he buried his nose directly against Dean's scent gland. 

The smell was exquisite and Dean respectfully kept his hands in place. "I can't imagine how you'll smell during your heat then."

Cas rubbed his nose against Dean's throat, getting drunk on that scent. Something like pine and sandalwood, and a clear winter's day, underlined by something that was as sweet as pie. "You can put your arms around me," he murmured, a soft groan falling from his lips.

Dean's arm gently wrapped around Cas's back, drawing him closer. Followed by a deep, long inhale. Dean was scenting him too.

Cas couldn’t help the groan. Dean scenting him in return made him hot all over and he squirmed against him. “Dean,” he breathed out, a mixture between a complaint and a groan.

That was met with a hum. "Yes, Castiel?"

"You're not making it easy on me," he whined against Dean's throat. He would really need a shower after this.

The warm chuckle that escaped was almost melodic. "If you need more, just say the word."

Cas leaned back from Dean's throat, needing to think clearly. "No, Dean." He hoped his voice sounded resolute because he wasn't feeling it. "You're here because I need to scent an alpha. I'm not in heat yet and I sure as hell don't want to use you only for my pleasure. It just feels… wrong."

Dean's eyebrows shot up at that. "That's why I'm hired, to be used for pleasure as well as medical reasons.”

Cas closed his eyes and sighed. "I know. But there’s a difference between having sex because I need an alpha to get through my heat for medical reasons, and having sex with you because I feel like it, not because I need it. I don't want to… just use you, paying you for something you don't really want. With the medical reason it's… I don't have a choice. I don't want to burden you with more than necessary. I can imagine your job is hard enough as it is."

Dean's expression was unreadable for a moment before he said, "Whatever you want." 

Cas closed his eyes before he snuggled against him again, his nose at his throat. "I want you to hold me and let me scent you, and in a week I would like your assistance during my heat. Would you be okay with that?"

"Of course," Dean said, wrapping his arm around Cas again.

Dean's scent was a little off and Cas leaned back to look at him. "Are you alright?"

"Perfectly fine," Dean said softly, it sounded recitative.

Cas knew he was giving Dean a bitch face. Who was the guy kidding? Cas had his nose directly at his scent gland. "Talk to me," Cas urged softly. "Did I offend you?"

Dean's expression was perplexed. "Why are you concerned?"

"Because if you feel uncomfortable, I'll feel uncomfortable, too." He shifted a little bit closer. "I know I'm not experienced in all of this. I've told you this is my first time with an alpha. I know you're only providing a service for me, helping me through this difficult time, but I can't help wanting to treat you like I treat every intimate partner. I don't know how to do it differently. I can't just stop caring about your comfort. That isn't me."

Dean held his gaze for a moment, an intensity burning behind bottle green irises. "You're being serious, aren't you?"

"This is my serious face, yes," he replied dryly. 

"My, uh, feelings have never been taken into account before." 

Sadly Cas wasn't surprised to hear that. He had a weird feeling in his chest. Dean seemed like a really nice man. He didn't deserve this. Not that Cas would ever say anything against the system. He knew it was necessary. He had paid attention in history class. After one war following the next, Omegas and Betas had overthrown the alpha regime two hundred years ago. The regime had been ruthless and destructive, keeping Omegas as slaves. Not anymore.

But Dean seemed to be… different.

"I'm sorry." He touched Dean's cheek, rubbing his thumb over his freckles. "As long as you work for me, I want to take your feelings into account if that is alright with you." Plus his scent was a million times better when the alpha was happy.

Dean gently grasped Cas's wrist. "This isn't a trick?"

Cas tilted his head in confusion. "A trick for what?"

"Reporting me to get a refund," he said simply. A clear strong voice of experience.

Cas's eyes widened in shock. "What? Are you saying… people do that?"

Dean let out a mirthless laugh. "Not everyone has insurance, and as a rare alpha… I'm more expensive."

Cas couldn't believe an Omega would do this. It was despicable. He shook his head before he leaned forward. "Scent me. I want you to know for certain that you can trust me. I would never do something like that, and I think the people who did should be punished for being despicable assbutts."

Dean's lips curled up in a small smile and he shifted, form turned to Cas as he leaned in close. "You're sure?"

"Yes," Cas replied before he chuckled softly. "My underwear is ruined anyway… but I want you to feel safe, just like I need to feel safe with you."

Dean nodded, carefully closing the space between them as his face turned to the crook of Cas's neck. He could feel the tip of Dean's nose on his pulse point before the alpha took a long, deep inhale.

Cas's eyes fluttered shut and he couldn't help but wrap his arms around Dean to hold him, pressing his face against his throat. Another wave of slick soiled his underwear and he groaned as he rubbed his nose against Dean's skin. He knew he would never get enough of this scent.

…. :::: :::: ….

Dean had never smelled an Omega scent this sweet before. When this beautiful blue eyed creature opened the door and that scent first filled his nostrils, Dean had instantly gotten hard.

Now in an embrace, truly scenting the Omega, Dean found himself struggling to contain his urges. The kindness was genuine, he could smell it. 

He could also smell the new gush of slick. Dean couldn't help but groan, "You smell so good…"

"You too," Castiel replied with a soft moan against Dean's throat before he complained softly. "I feel disgusting."

Dean chuckled. "It's good to know we won't have to use synthetic slick when the time comes." It was only necessary for clients who weren't scent compatible.

"Yeah," Castiel breathed out, his voice sounding husky. "I don't think I have ever been so wet in my life. I had no idea the right scent would be so impactful."

Dean's cock was painfully hard, and he knew he would strip his dick later to the image of clear blue eyes and the distinct smell of cherry pie when he returned to the agency. He took another whiff along the skin of Castiel's neck with an appreciative groan. "That amount of slick will definitely make it easier on you during your heat."

His knot was larger than most.

Castiel hummed in agreement. "I think so, too. All the times before have been very difficult. It feels so easy with you."

There he went again with the kindness. Dean was so unfamiliar with the gesture without it being tied to sexual gratification. Although this would be the first time he would gladly knot an Omega for free. 

"I bet you taste good," Dean purred into Castiel's ear.

He could smell fresh slick on Castiel as he groaned and pressed his lips against Dean's scent gland. The sudden jolt of pleasure came entirely unexpected, reminding him that he hadn't talked about boundaries on the topic of scent glands and marking.

Dean reluctantly drew back with a shallow gasp, hand braced at Cas's pulse point. He had never wanted to mark someone in his entire life, assuming that was a fallible genetic code in the more aggressive alphas, until now. Not that bite marking was legal.

"Castiel," Dean breathed out through a groan. Lips trembling with the urge to feel that skin against them. "How comfortable are you with my lips touching your skin? I will not mark you."

The fresh smell of slick was definitely an answer, but he needed to hear it from Castiel's lips. "I… I don't know," he replied hesitantly. "I don't know you well enough to feel safe doing that. Um, what about you? I mean, obviously I can't bite you… but…"

"You're allowed to touch me however you like," he said. They all had to tell clients that, but this was the first time Dean didn't mind that rule.

Cas gave him a soft smile before he sighed. "Okay I can't do this any longer." He got up from the couch with a grimace. "I know our hour is almost over so how about we hash out some organizational things."

Dean tugged at the leg of his jeans to adjust his cock. "What would you like to hash out?"

He could see Castiel's eyes dropping to his jeans. He stared for a second before he quickly looked at the ceiling. "Um… so my insurance is paying for daily one hour visits. So I'll need a time that works for you. Also, if you're okay with it, next time I want to do this on my bed without clothes. Because this situation is just very uncomfortable." He gestured to his own pants.

Dean moved to stand. "I haven't been scheduled for anything for two weeks at least, so you give me a time and I'll be here."

Castiel nodded then. "Six pm would work for me. After work." He shifted from one leg to the other. "My second question is about my heat. It's usually three days and very intense. I would like to book you in full for that time. Could you manage to stay overnight?"

Dean almost did a double take. He'd never been requested for such a length of time, especially not by an Omega who was in a relationship. "You want me here that long?"

"Yes." Cas looked embarrassed then. "It's especially hard at night." He sighed softly before he added, "This can be a long term arrangement. My doctor said it could take a year until I finally lose my fertility."

It must be bad then, of course, he hadn't met an Omega who didn't want children before, so that could be why. He nodded and flashed Castiel a small smile. "I will stay as long as you need me." Dean pulled his shirt back on and grabbed his jacket. He inhaled the enticing aroma of Cas's slick one more time and nodded to the door. "I'm sure your boyfriend will appreciate your state."

Cas gave him a crooked, embarrassed looking smile before his expression turned earnest. "Thank you for today. I feel better than I have in ages." The smile he got then was absolutely genuine. "I'm looking forward to tomorrow."

"Six sharp," Dean said as he held his hand out to Castiel. "It was nice to meet you, Castiel."

"Likewise," Castiel said as he took his hand. His fingers felt strong. "And please, call me Cas."

Cas. That really suited him. "Have a good evening, Cas."

Dean departed with a weird feeling in his chest. He had never felt anything like it before, and he wasn't entirely sure he liked it. As Dean looked up at Cas's now closed front door, he couldn't help but sigh.

He knew he would need to be careful with this one. The only thing dumber than an inbred alpha, was one who was dumb enough to believe they could have a real future with an Omega.

Chapter Text

Chapter 2

Dean was staring at his reflection in the cracked mirror, crookedly hung on the wall of his room, straightening the collar of his flannel shirt. It was the nicest shirt he owned.

Benny appeared behind him in the reflection, baring his teeth in a grin. "Don't you look snazzy?"

He elbowed Benny's stomach to knock him out of view. "Fuck off."

That was met with a bark of laughter as Benny dropped himself onto Dean's bed. "He must be cute. You only wear that shirt when they're cute."

Dean rolled his eyes and grabbed his jacket from the foot rest. "He's… nice."

"Nice?" Ketch scoffed in his prissy accent. "There's no such thing as a nice Omega. They only want one thing from us."

"Hush!" Garth bit out. "You really want to get thrown in the kennel again?"

Ketch made a rude hand gesture and Garth started snarling at him. When they both started growling, Dean shrugged on his jacket and opened the door. 

"Don't let him kill Garth," Dean said to Benny before he closed the door behind him with a soft exhale. He made his way down stairs to the lobby, where he scanned the chip in his forearm to open the door.

It was the only way in or out, and how they made sure alphas didn't stay out past their scheduled times.

The trip to Cas's place took Dean through a large park, and the smells… so many different assaults to his nose. Some great; sweet flowers, affection, love. And some… not so great. Either way, this was the closest to freedom he would ever get to experience.

And still, nothing he smelled on the journey came close to the aroma on Cas's doorstep. His scent was so heavy, and again, he had to tug on his jeans to try and hide the bulge.

With a deep appreciative inhale, he knocked on the door.

When Cas opened it, his hair was a little messy, face flushed. His scent was even heavier now and he could clearly smell the Omega's arousal. "Hello, Dean," Cas greeted in a husky voice as he let him in. His white dress shirt had a few buttons open, the blue tie loosened and skewed. 

Dean removed his jacket and flashed him a small smile. "Should we get started?" Dean could sense an almost need in the Omega.

"Yes." Cas started to unbutton his shirt as he nodded at him. "Follow me." He guided Dean through his really nice apartment and into his bedroom. Everything was so clean and tidy. The bed was big, with an iron cast headrest, fluffy pillows, and black satin sheets. 

Cas quickly shrugged out of his shirt and pulled off his tie, hanging it over a chair before he opened his pants. "You were okay with me being naked, right? I feel uncomfortable in my clothes when we do the scenting."

Dean didn't get a choice in whether or not he was fine with such a thing. Whatever made the client happy. Although, in this case, Dean was absolutely fine with it. He nodded. "Whatever you need. Would you like me to undress as well?"

Cas gave him a contemplative look. "Um, only if it makes you feel better. You really don't have to. I just hate wearing wet underwear and it's not a problem you will have." And with that he quickly got rid of the rest of his clothes, before climbing into the bed and under the thin blanket. Dean didn't get a good look before Cas had hidden the lower part of his body.

Dean toed off his shoes and crawled into the large bed. He settled himself next to Cas. "Whenever you're ready."

The blanket separated them, but Dean figured that Cas wanted it that way. Cas gave him a quick smile before he crawled into his arms and put his head on Dean’s shoulder, pressing his nose against his throat. He inhaled deeply and sighed. “I was looking forward to this all day,” he mumbled. Dean could practically feel Cas relax against him.

Dean chuckled as he tried to keep his own arousal in check. It wasn't often he was hired for an Omega who smelled as nice as this one. "If you ever need me to arrive earlier, I can."

"I wish," Cas replied with a soft laugh. "I have to work pretty long hours." He hummed softly, his nose rubbing against Dean's sensitive skin. "I can't believe I was so against trying this before," he mumbled again. "My doctor was right. This really works."

"I'm surprised you're still working in this state," Dean said, resisting the urge to scent Cas back. 

"I really love my work. My students. I don't want to leave until it's absolutely necessary." He sighed deeply before he wrapped his arms around Dean, pressing closer.

Dean couldn't help but smile. He wondered if his brother ever became a teacher like he wanted. "You're very dedicated."

"It's easy when you can do something you love." He could feel Cas tensing up against him. "I... I apologize. That was probably insensitive to say."

Dean chuckled. "Who's to say I don't love what I do?"

Cas pressed his palm against Dean's shirt before he leaned back to look at Dean. "Do you?"

"Love is a strong word, but of the options I'm allowed to have, I'm content."

Cas gave him an intense, soul searching look before he nodded and leaned back against him with a sigh, inhaling deeply. "If you had... a choice, what would you want to do? I’m sorry if that is too personal a question. You don’t have to answer that."

It wasn't that it was too personal, moreso that Dean never really thought about it. There was only one other job for alphas anyway. "I'm sorry, I haven't ever thought about it."

"That's okay," Cas replied after a while. "It's probably more healthy anyway." He sighed again before he asked, "Do you want to scent me in return?"

"If you are okay with that?" Dean was surprised, he never usually worked for an Omega who wanted reciprocity.

Cas nodded against his throat, his breath hitching a little. "Only if you want to, of course."

Dean couldn't stop himself, he carded his hand through Cas's hair to draw him back enough that Dean could scent his neck. He took a deep inhale, and somehow refrained from shuddering at the way this magnificent scent caused his cock to twitch.

He could feel Cas's fingers tightening at his shirt when the scent of fresh slick drifted to his nose. Cas gasped softly, pressing his face closer against Dean's neck, basically rubbing his cheek over Dean's gland, scent marking himself.

His cock twitched again. This was the first time he actually looked forward to an Omega's heat. Dean inhaled again, screwing his eyes shut with a soft groan of appreciation.

"I don't know why," Cas groaned before he inhaled deeply, "You smell even better when you scent me."

"You're smelling my arousal," Dean said simply before he inhaled again. Honestly, he would love to scent Cas's groin, maybe even see how much slick he gushed out… Dean hummed at the thought.

A soft whimper fell from Cas's lips. "Do you smell mine?"

Dean couldn't help the growled, "Yes."

Cas was breathing heavier now, squirming against him. "I’ve never felt like this before... Like, just smelling you makes my knees weak and I feel... so turned on."

As Ketch's words filled Dean's head, he said, "You haven't met an alpha before."

Cas scoffed. "I had run-ins with alphas before. None of them smelled like you do."

Dean furrowed his brow, a weird possessiveness suddenly washing over him. "They didn't hurt you, did they?" He growled.

Cas leaned back to look at him in surprise. "No... just dumb comments... But I have to confess I was always afraid of... you know. That's why I hesitated trying out the service your agency provides. I've been with other Omegas all my life. Even Betas too..." He shook his head.

Dean flashed him a small smile. "While a lot of us are aggressive, some of us are able to control our nature."

"Even when..." Cas chewed on his lower lip before he looked up at him. "Even when an Omega is in heat?"

Dean nodded. "Hence why I'm considered submissive. Despite my urges, I can keep them in check."

Cas gave him a curious look. "But um, do you like it... sexually? When an Omega is dominant?"

"I do. There's something about an Omega that takes what he wants," Dean said, another soft groan escaping at the thought of seeing Cas in that state.

Cas licked over his lips, giving him a hungry look. "For the first time in my life, I think my next heat won't be so bad..." He closed his eyes, inhaling deeply before he settled against Dean again, his nose pressing against Dean's throat. "Oh, um, what I wanted to ask... since you're staying overnight and all... are there certain things you really like to eat or drink? Just so I know what to shop for."

Dean furrowed his brow. "You aren't obligated to feed me."

He could practically smell Cas's confusion. "What are you talking about? I'll need you to have all your strength and energy those three days. So, of course I will take care of you."

Dean nodded. "The agency will provide me with nutrition bars."

Cas hesitated for a second. "That sounds disgusting."

"It's definitely not a cheeseburger," he said with a laugh.

"So you would be okay if I cook something for us? I actually like cooking," Cas said after scenting him deeply again.

Dean's cock twitched at feeling Cas against him. "You may have to check with the agency," he groaned, "our diets are… strict."

"I can do that," Cas replied softly before he asked, “How would they know if you eat something different?”

Dean shrugged. "I'm honestly not sure."

"So, theoretically you could just eat with me and throw those bars away? And no one would notice?" Cas asked, nudging his nose against his skin.

Dean tensed. This felt too safe, too good to be true. "I… I don't know."

"I can ask the agency if that makes you feel better?" Cas said in a soothing voice, stroking Dean over his shoulder.

“Uh, yeah.” Dean murmured, utterly confused by this Omega’s kindness.

Cas chuckled softly. "Do you want to scent me again? I had the feeling it helped you, too... getting to know me."

Dean looked at him, unable to comprehend Cas. “Why are you so nice?”

Cas raised his eyebrows in obvious surprise. "Um... why wouldn't I be?"

Shit. Dean shouldn’t be taking conversations in these directions. “No reason,” he said quietly.

Cas reached out, gently touching Dean's cheek. "Look, Dean. I think we both... had bad experiences with the other gender. And I know that I'm not... free of prejudice against alphas based on prior experiences. But... you haven't given me any reason to make me not like you."

“You like me?” Dean hated how timid he sounded. 

"Um, yeah. Since we met, you have only been extremely nice to me... Why wouldn't I like you?" Cas asked softly.

Dean rubbed the back of his neck. “Because I’m an alpha.”

"Well, first and foremost... you're Dean." Cas gave him a soft smile before booping his nose playfully.

Dean slowly drew his finger to his own nose, touching where Cas had touched. He looked at Cas again, as though he were a puzzle he couldn’t put together. “You are unlike any Omega I have ever met, Castiel.”

"Well, you're definitely unlike any alpha I have ever met," Cas replied in kind.

Dean couldn’t help but smile. “I… I like you too.”

…. :::: :::: ….

Inias was the first one who noticed, and during their weekly movie night. Like always. He bumped into Cas’s shoulder, giving him a raised eyebrow before he told him to get his ass over to his apartment and quickly call his alpha. 

It was one day too early. Dean had already left an hour ago, and Cas didn’t even know if he had time to come back. He quickly hugged Inias before he sighed, “Damn it… I can’t believe I’m really going through with this.”

Inias laughed. "He's not that bad, is he?"

“No, he is… actually really nice. But I’ve never spent time with him while being in heat so who knows if that will change.” Cas sighed, giving Inias a pained look as he felt his skin crawling and getting warmer. “I should go… Um, see you in three days?”

"Yeah, and if he gets crazy, you call me. Alright?" Inias actually sounded concerned.

It wasn’t helping at all with his own nervousness. He pulled Inias into a tight hug. “Fuck, why can’t all of this be easier?”

Inias rubbed a soothing circle on his back. "I don't know, probably some cosmic practical joke."

Cas chuckled at that. “Yeah, that sounds about right.” He leaned back, giving Nias a soft smile. “Maybe he is busy. Then it will be just me and that dumb toy you bought me.”

Inias barked out a laugh. "One day you'll thank me."

Cas gave Inias one last long look, cursing his fate before he pressed a kiss to his cheek. "Keep your phone close by, just in case I send an SOS."

"You know I will. Now go call him before it gets bad."

Cas nodded, feeling a little bit safer now as he returned to his own place. He had the agency programmed in his phone, nervously pacing in his living room as he called them.

When the operator finally answered, Cas stumbled over his own words, "H–Hello, It's Castiel Novak. My alpha is Dean. I... My heat is starting and I know Dean probably just got back, but I'll need him here again. Is that possible?"

There was some audible typing that accompanied the beat of no response before she said, "Ah, yes. Mr. Novak, with your Delta Plus plan we can. Would you like us to send him by car? Or is it to the degree you can wait thirty five minutes?"

He knew his heat would get bad any minute now. "No... he... by car, please. Thank you."

There was more click clacking against the keyboard before he heard, "Alright, your alpha should arrive in twelve minutes. I would recommend undressing and prepping now. Is there anything else I can assist you with?"

Cas really didn't like how intrusive her recommendation was. "Um, yes. I already told someone that he will stay three days and overnight. He told me he is provided food from the agency. Will it be okay if he eats with me instead?"

"Our alphas maintain a strict diet for their specific health needs. We will bring his supply in the morning. And is there anything else?"

Cas really didn't like that, he switched his tone to authoritative. "Then please email me the requirements for his food. As long as he is under my care, I wish to provide the healthy diet for him."

There was a beat of silence, and a click of the tongue. "Alright," she clipped, "A note has been made in the account and an email will be sent, but if he comes back malnourished, you will be charged twenty seven hundred dollars for each pound lost, and insurance won't cover that."

"I will take good care of him," Cas growled before he hung up on that bitch. His skin was already sizzling with the heat and he felt horrible in his skin. 

Although he didn't want to do what the secretary of Hell had told him to do, he needed to get out of his clothes, badly. The heat between his legs was uncomfortable and his finger went there without being able to stop himself. There wasn't enough slick as always. And it didn't feel good, as he tried to prepare himself. So he gave up. He needed Dean... Bad. Dean would be able to make him wet.

It was both the longest and shortest twelve minutes of his life when he finally heard a knock on his door.

He quickly threw on his black satin bathrobe, the only thing he could tolerate on his skin as he carefully opened the door. It was Dean. He quickly let him in, closing the door behind him before he wrapped his arms around him, pressing his nose against his throat. "Fuck, I...  sorry, my heat came earlier than I... expected."

Dean didn't respond at first, and his chest was heaving with the way he was panting.

"Dean," Cas practically growled. "You need to help me with prep. I can't... I can't do it without you." He grabbed Dean's wrist and pulled him into his bedroom, shrugging off his bathrobe before he growled, "Get out of your clothes, now."

Dean nodded, eyes never leaving Cas's form as he ripped open his shirt and roughly yanked his pants down. The alpha boxers did nothing to conceal his enormous cock, and yet Cas still wasn't prepared for the sight when they too were yanked off. 

It was weird, a part of him was intimidated by the sight, but his Omega side got wet in anticipation. He pointed to the bed. "Get up there, on your back."

Dean complied immediately, sprawled out on the bed, his dick at attention.

Fuck, how could Dean's knot already be so thick? Cas crawled onto the bed and onto his lap, before he leaned forward to scent Dean's incredible, enticing smell. "Fuck, Dean, please, make me wet... alpha."

That was met with a growl as he gripped Cas's hair to present his neck. He took a deep inhale and suddenly it felt like he was drowning in the scent of the alpha's unadulterated arousal.

A gush of slick ran out, dripping down the back of his leg, followed by a horrible ache of emptiness in his hole. "Finger me open, alpha."

Dean's other hand slipped between Cas's legs, he could feel deft fingers mop up some of the slick before the first digit plunged inside.

It didn't hurt. But Cas didn't have time to think about that because Dean's finger drilled deeper inside, rubbing over his prostate. Fuck. Cas had never felt anything so amazing before. 

His heat grew worse in that moment, and he groaned with the onslaught of sudden need. "Dean, more," he growled, before he whined, "Scent me."

Dean's nose nuzzled against his pulse point as he scented him again, a second digit working it's way into Cas's hole.

Cas gasped in lust, his hips riding Dean's digit on their own as more and more slick ran down his leg. He had never been so wet before in his life. Goosebumps ran all over his skin with Dean's nose being so close to his scent gland. It was dangerous. He knew that on some level, but it was an incredible turn on to feel Dean scenting him there, both of them barely hanging on to their control. Cas trusted Dean though. He didn't know why, but there was something about Dean that made Cas at ease with everything. "Uh, Dean," he groaned. "Give me another one, please."

Dean's fingers began a scissoring motion, opening his hole enough that the third slipped in with ease. As he started fucking his fingers into Cas's hole, he scented him again, the exhale coming out in a low growl.

Dean's growl made Cas even more wet. Fuck, why was that so hot? "Lick my neck, alpha," he moaned out softly as he started to fuck himself on Dean's fingers.

The heat of Dean's tongue against his skin sent a shiver down Cas's spine. A fourth finger worked its way in as Dean kept licking his neck like a milk starved pup.

Cas felt like he was dying from need. "Dean, fuck... pull out your fingers." He needed Dean's cock now, somehow all of him was really looking forward to even taking the alpha's massive knot. He waited for Dean to pull them out, whining at how open and empty it made him feel, before he slid back and grabbed Dean's thick erection, guiding him to his entrance. "Hold still. I'm going to ride you and I don't want you to move." He gave Dean a serious look, searching his eyes. “Alright?”

Dean's pupils were lust blown, and his hooded gaze had a primal look, but he nodded. He really was a submissive alpha.

"Good boy," Cas praised as he slowly slid down on Dean's cock, letting it sink in. He howled in lust, his eyes closed as he sank down until the starting of the knot stopped him. Fuck, that thing was already huge. 

His eyes found Dean's again before he started to slowly ride him, his wet hole making obscene noises. Fuck, it felt so right and so good. Sex had never felt so right before. He quickly upped his pace, carding his fingers through Dean's hair as he praised him again for still lying there and not moving. "You're such a good alpha."

Dean replied with a growled moan, hands fisting the sheets as he watched Cas with hunger in his eyes.

He really liked that Dean was looking at him like that. It gave him a thrill that he hadn’t felt before. Just like feeling Dean’s lips and tongue against his neck. Just thinking about it, made him slick even more. He upped his pace, but it still didn’t feel like enough. He needed Dean to go deeper. He was pushing against Dean’s knot, but it was so big, he had no idea how it would go in. 

He wasn’t sure he could do it. Cas leaned closer to Dean’s beautiful face. “Dean… I need your knot,” he whined.

Dean nodded, his hand snaking to Cas's hole. He started massaging Cas's rim. "Slow," he grunted, his voice a deep, animalistic octave.

Cas whined again in lust, pushing against Dean's finger as he continued to ride him. "Dean, I... can't wait to feel... you coming inside of me," he growled, his control starting to slip with the sheer amount of lust he was feeling. He had never begged before, for anything, but he couldn't stop himself now, "Please, I need it."

Dean massaged his rim wide enough his knot started to push through. "Cas," he growled, hungered gaze intense, the green in his eyes darkened as he looked at Cas.

"Fuck, fuck, fuck," Cas cried out as his hole got stretched on that knot. It would really go in at this rate. And fuck, he wanted, needed it so much. "Yes, Dean. Please. Move! Push it in."

Dean's hands gripped each of Cas's ass cheeks, lewdly parting them, stretching his hole wider before suddenly that knot pushed past the tight ring of muscle. The sound that escaped Dean was a pure, almost savage growl.

Cas cried out in lust as his knot pushed him into an orgasm and he came all over Dean's stomach as he milked Dean's big, fat knot.

Dean grunted, eyes widening when suddenly Cas was being filled with the alpha's hot seed.

He could practically feel getting his senses back with every drop of sperm that was pumped inside of him. Dean's knot was firmly locked inside, pumping a fresh load of seed into Cas when he moved his hips a tiny bit. It felt glorious. He looked down at Dean, feeling a lot better before he softly asked, "How long does it usually take for your knot to go down?"

Dean exhaled slowly, flashing Cas an apologetic look. "An hour, sometimes longer."

Cas raised an eyebrow before he chuckled softly. "That's impressive," he said before he squeezed his channel around Dean's knot, milking it. He loved how he had complete control over Dean's pleasure like that. "I… thank you," he said finally. "I already think this will be the best heat I have ever experienced."

Dean flashed him an almost dazed smile. "I'm glad you didnt try to suffer."

His hair felt so soft under his hands. "I'm glad that my initial worry was without any base. I trust you, Dean. I trust you with my heat."

"You… trust me?" he asked, voice surprisingly timid considering the gruff, dominating alpha growls that escaped him just moments ago.

“Yes,” he replied softly, giving him a smile. He got a little lost in Dean’s beautiful eye color. “I’m… I’m very happy that I’ve met you.”

The way Dean looked at him in that moment, as if Cas had created the universe, was breathtaking. "Me too," he murmured softly.

…. :::: :::: ….

Dean woke up to a lack of body heat. It took a few blinks before Dean realized where he was. On the satin sheets of Castiel's bed.

He sat up and ran his palm along the space Cas had occupied when they had finally exhausted each other.

It had been such an intense experience for Dean. He had never smelled anything that sinfully sweet in his life. And he had never come that quick either.

Dean had no idea what that meant, if it meant anything, but he grew weirdly concerned in that moment, and got up to find the Omega.

It smelled like something sweet from the kitchen, something that wasn't Cas. When he followed the smell, it got mixed with the alluring sweetness of Cas's scent. The Omega was standing in the kitchen, only wearing black boxer shorts, a sheet of paper in his hand as he was whistling and stirring something. 

Cas shifted to look at him then, his smile widened. "Good morning, Dean. I hope you're hungry. I've made pancakes."

"Pancakes?" Fuck. Dean hadn't had pancakes since before he presented. He moved to sit on one of the stools, the cold metal against his bare skin would hopefully keep his arousal in check.

"Yeah, with blueberries." Cas put a plate in front of him with a juicy sweet looking pancake that made his mouth water. "Don't worry, your agency sent me a nutrition list. I'm allowed to take care of your needs."

Dean couldn't help but stare at this mystifying Omega. He was so earnest, genuinely kind. Dean wanted to stay guarded, but he found himself feeling affection for Cas, which was a dangerously dumb thing to do for an alpha. "This is very kind."

Cas shook his head as he sat down next to him with his own plate, the scent of his heat now more prominent in Dean's nose. "I like cooking, taking care of someone. And you're helping me so much."

Dean flashed him a smile as he grabbed his fork. It was an awkward utensil in his grip. He used to know how these worked. Dean just wrapped his fist around the long bit and stabbed the cakes. He managed to rip a small piece off and tried to draw it to his mouth. He growled when it fell onto the plate.

Cas got up and walked behind his back, putting his chin on Dean's shoulder as he grabbed the hand holding the fork. "Relax your hand," he murmured in a soothing voice before he shifted Dean's fingers to hold the fork differently. He then grabbed his other hand, handing him the knife as he guided him to show how they worked. "Just like that. Now try for yourself, Dean."

The Omega's scent was intoxicating, he couldn't stop himself from craning his neck to deeply inhale against Cas's gland.

Cas gasped as he pressed closer and Dean could smell his fresh slick and arousal. "I'm sure, um, it's…" Cas exhaled deeply before he stepped back, returning to his own seat. "Easier with the knife. You can also push the pancake on the fork."

Dean licked his lips and nodded slowly. He adjusted the fork, willing his erection to go down as he shakily managed to get some of the cake onto his fork. He held it up and it stayed put. Dean flashed Cas a broad grin before he stuffed it into his mouth.

"Holy fuck," he growled at the sweetness that hit his tongue.

Still not as sweet as Cas's scent.

Cas was watching him with a wide smile that reached his eyes. "Do you like it?"

"This is the best thing I've ever tasted," Dean murmured before he started shoveling more into his mouth.

"You haven't tasted me, yet," Cas suddenly growled before he clasped his hand over his own mouth, looking at him in shock. "Um, sorry. That was the heat talking."

Dean sat there, fork suspended in the air. He swallowed dryly, trying to keep himself from knocking everything off of the table and doing just that. "I already know you'll be sweeter."

And by god he meant it.

Cas licked over his own lips before he swallowed visibly. His alluring scent got stronger by the second. "Yeah, um… I don't know if you're comfortable with that, but maybe you want to… lick me open?"

Dean nodded, only a growl escaping. That was another first. He knew some of the alphas couldn't speak when around an Omega in heat, but that had never been a problem for Dean before.

"Fuck." The fork and knife clanged against the plate as they fell out of Cas's hands. "Your growl… is so sexy… Dean… we’ll eat the rest, um, later… I need… need."

Dean dropped his utensils and stood up, cock hard as a rock and jutted out at the Omega. He stood, breathing ragged as he awaited his command.

Cas got rid of his boxer shorts as he grabbed Dean's wrist and pulled him back into his bedroom. Cas laid down on his back, spreading his legs for Dean. "Come here, Dean and lick me."

Dean had never moved so fast in his life. He crawled onto the bed, scenting Cas's groin before he dove in, his tongue lapping up the fresh slick. And it was… as though all the best flavors that existed had come together. A sweetness that made his tongue sing and he growled as he plunged inside, licking the walls of that tight channel.

Cas was losing it under him, arching his back up as he groaned loudly, spreading his legs even more. He was producing more and more slick, his fingers suddenly flying to Dean's head, gripping his hair. "Fuck, Dean… alpha, yes. Please."

Dean growled, the sound muffled, and he used his index finger to mop up some slick, working it inside along his tongue. His cock throbbed with need, but he needed to keep tasting this beautiful Omega.

The fingers in his hair started to pet him. With a growl, Cas braced himself on his elbows and watched Dean with a hungry, heated expression. "Don't stop until I have four fingers in me. Stretch me well for your... fuck... knot."

Dean nodded, working in a second finger as he gently drew back. His breathing was ragged as he watched that hole suck his digits in. He couldn't stop himself from scenting Cas again, causing his cock to twitch and precome to drip on Cas's leg.

Cas cried out in lust, his fingers tightening in Dean's hair every time he touched his prostate. "Fuck, Dean, more. Need more. I feel too empty."

Scissoring Cas open, that inviting hole fluttering as it gaped. In a one two thrust movement, three then four digits started stretching Cas wide. Dean growled again, lapping at the slick that dripped down, his tongue accidentally grazing Cas's balls.

"Fuck!" Cas cried out. Dean could see his hard cock twitching, precum beading, delicious drops at the head of Cas's cock. "Dean, stop. I'm ready for you. Fuck, um, I want you to sit on the bed."

He couldn't wait to feel Cas again, so Dean eagerly obeyed, sitting on the bed, back braced against the headboard, and painfully hard cock jutted out, pointed at the Omega.

Cas crawled over him and into his lap, pressing his face against Dean's neck as he suddenly started licking his scent gland with a moan. He reached behind himself, strong fingers gripping Dean's cock as he guided it to his hole and started to tease it with a soft growl.

The urge to thrust up was overwhelming, but he took control with a shaky exhale, focusing on something. His gaze landed on blue irises and lust blown pupils. "Beautiful," Dean managed to breathe out, voice still a deep growled sound.

Cas gave him a beautiful smile, touching his cheek. "You're doing so well, Dean. You're such a good alpha." He teased the head of Dean's cock a little more. "Do you want me?"

Dean nodded, turning his face to Cas's palm on his cheek, licking the heated skin. "Cas," he growled. It was getting easier to speak his name.

Cas leaned closer to his ear, a soft moan falling from his lips. "Take me," he finally commanded.

The growl that escaped was purely instinctual, the need to breed this Omega, his Omega, and he gripped Cas's hips, guiding him down on his cock. The heat stole the breath from his lungs.

Cas looked so beautiful on top of him, bracing his feet on the mattress as he started to ride Dean, his head thrown back in lust, exposing his throat to him, like an invitation.

Dean's hand reached out, braced against Cas's pulse point. He let out a deep, needy, "scent." Alpha needed to scent his Omega.

Cas gave him a heated look, a soft whine as he slid closer to Dean's face, offering his throat. "Yes, please, scent me, alpha."

He rubbed his nose along Cas's neck, before taking a deep inhale. It caused Dean's cock to twitch, the sweet, alluring, intoxicating scent. 

Cas growled and rode him harder, his knot bumping against his Omega's entrance. "Lick me there, please," his Omega pleaded huskily. "Feels so… so right."

Dean couldn't help but growl again as he licked Cas's scent gland. While the taste wasn't comparable to his slick, he was still so sweet. The urge to sink his teeth in sideswiped Dean and he drew back, growling as he forced his head away.

Cas gave him a heated look as if he had noticed Dean's urge. His fingers found his chin as he rubbed his thumb over Dean's lips. "Take me harder, Dean. Need your knot."

With a nod, he gripped Cas by the hips and started fucking up into him, his knot pushing deeper with each thrust.

"Yes, fuck, you're so big. I'm gonna come when you push it in, fuck," Cas was losing his rhythm on top of him, gripping Dean's shoulders to hold on. 

Dean's hands slipped to Cas's ass cheeks and spread them, forcing him onto his knot. A savage growl escaped when it was inside his Omega. Dean's head lolled back against the headboard as pleasure washed over him.

The moment he was locked in, Cas cried out and came all over Dean's stomach in hot white streaks, his tight wet channel milking his knot, making sure all of his alpha seed pumped inside of his Omega. "Oh, fuck, yes," his Omega whined, slowly and softly riding him. "Feels so good."

Dean nodded as his grip tightened on those sharp hips, filling Cas with load after load. "Good," he grunted in agreement, brain still coming down from the high of their breeding. 

Cas bent over, pressing his forehead against Dean's, breathing fast. "Dean," he whispered softly. "Why does this feel so right?"

Even if he had the ability to speak properly in that moment, he wasn't sure the words existed to explain it. All he could manage was a soft, "Compatible."

Cas hummed in agreement before Dean suddenly felt his lips brushing over his own. It was only a moment before Cas settled his face against his throat, breathing in his scent. "I'm tired," he mumbled.

Dean's lips were tingling from the brief contact, a pleasant warm sensation that coursed throughout his entire body. He suddenly felt very protective of Cas, and he raked his fingers through Cas's hair, massaging his scalp as he held him close. "Sleep," Dean said, voice soft. His knot wouldn't go down for at least an hour.

Before Dean could fall asleep himself, he could feel Cas’s lips pressed sofly against his scent gland as he murmured, “Mine.”

Another pulse of seed filled his Omega at the possessive claim, and even though he could never say it, Dean fully felt that sentiment in kind. He drifted off to the wish that he could actually have this.

…. :::: :::: ….

Cas felt thoroughly confused about his feelings for the gentle alpha. After eating the leftover breakfast, they returned to bed to cuddle. Cas was leaning against Dean’s broad chest, his nose close to his throat as they were drinking some orange juice and watching a soap on TV, something with a doctor in cowboy boots, who had ridiculous problems. Cas wasn't paying much attention.

He leaned over to put his empty glass next to Dean’s on the nightstand before he looked up at him with a soft smile. “I have never felt so settled before during a heat. I’ve only associated that time with stomach cramps and going stir crazy with need.”

Dean flashed him a small smile. "It's strange how our biologies balance each other out."

“Yeah,” Cas quietly replied after a moment. He hated it though. Being dependent on an alpha. Although he wasn’t in a relationship with anyone at the moment, he wondered how this would have affected him then. It was just unfair that he couldn’t feel this way with an Omega. That their biology was forcing this on them. Just as it was unfair that Dean’s life was so heavily regulated just because he presented in the wrong gender.

He pressed his nose against Dean’s throat, inhaling deeply. He wished Dean wasn’t an alpha, and that left him all kinds of confused.

Dean hummed as his hand carded through Cas's hair. "Are you missing your boyfriend?"

“Mmh, what?” Cas asked as he looked up at Dean. It was then that he remembered what he had told Dean. “Oh, um…” He shook his head. “Inias and I… we’re not together anymore. For quite some time actually. I’m sorry, I just… at our first meeting I felt safer saying that he was still… my boyfriend.”

That was met with a small chuckle. "That's actually more common than you think."

Cas couldn’t help but laugh. Yeah, he could imagine that. “I haven’t been very lucky so far with relationships. Inias was… probably the best boyfriend I ever had, and although he is my best friend, it just didn’t work out.”

"Why didn't it?" 

“I don’t know. Certain things that I appreciate about him as my friend, I found very annoying as his boyfriend. He had the same problem with me.” Cas shrugged and snuggled against Dean’s shoulder, draping his arm around him and pulling him closer to his chest. “I’m glad that I don’t have anyone at the moment. I couldn’t have done those things with you if I had someone in my life.”

Dean hummed again. "But it's your biology, you can't help it."

“I don’t care,” Cas growled. “I would rather suffer through my heat than be intimate with someone outside my relationship.”

Dean nuzzled Cas's neck, an innately calming gesture. "You don't have to suffer right now."

"No," he replied with a soft sigh, closing his eyes. "Sorry, I didn't mean to... Honestly being with you just reminds me of how much I miss a relationship."

"If you miss it, why don't you get one?"

"Because for the next year I will have you for starters." And Cas tried not to think about how much he wanted to see Dean even after his heats were over. "Also, you would be surprised how few people are interested in an Omega who doesn't want kids and is a boring workaholic."

Dean furrowed his brow. "I think if more people did that, we'd have less abandoned pups."

Cas chewed on his lower lip as he got lost in thought. "Can I ask you a personal question? You don't have to answer it."

"Sure," Dean said, tone a little bemused.

"You've mentioned abandoned pups before. Is that something... you have personal experience with?"

Dean let out a soft sigh. "Those pups are forced to stay in alpha camps until they present, and even if they present as an Omega or Beta, by then it's too late to adopt."

It wasn't that Cas was uninterested in political things. He knew that the system in place was far from perfect. He hadn't voted for the current president, but he knew that this one hadn't done much to improve the situation for people in need. In fact, he made it even worse.

Cas sighed, touching Dean's cheek. "But you had a home, right? Before you presented."

Dean's expression grew sad. "I did."

Cas could practically smell his sadness. On instinct he leaned forward and pressed a kiss to Dean's throat. "I'm sorry. I didn't want to upset you."

"I just… try not to think about that time," he murmured, his lips pressed to the crown of Cas's head as he spoke.

"Yeah, I can understand that," he replied softly, before his fingers slid to the nape of Dean's neck, scratching it softly. "I have another question... that has been on my mind since my heat started. I hope it's not inappropriate so, um… keep in mind that I don't have any prior experience with alpha services." He swallowed dryly before he looked at Dean. "Are you... allowed... or okay... with um, kissing me?"

Dean let out a soft hum of appreciation at Cas's ministrations before he looked at him, green eyes alight with something Cas couldn't quite pinpoint, but it wasn't bad. "Most Omegas don't want to kiss me."

"I do," Cas replied hesitantly, still hoping he wasn't crossing a line. "But my question here is... do you?"

Dean gently cupped Cas's face. "I might not be very good at it."

"It's not that hard," Cas whispered before he leaned forward and pressed a gentle kiss to Dean's beautifully soft lips. He moved his lips over Dean's, his tongue hesitantly tapping against Dean's upper lip. His heart was beating out of control and it had been a long while since he had felt like that. 

Dean's hands were on either side of Cas's face as he parted his lips and granted Cas access, his tongue darting out to lick at Cas's tongue.

Cas couldn't help the moan as he felt Dean licking over the sensitive area. He reacted on instinct, without thinking he turned on the bed and pulled Dean on top of him, never breaking the kiss. The alpha's weight pressed him down into the bed and he could feel his ass getting wet with an onslaught of slick.  

Dean's movement became fluid, his lips slotting with Cas's, a hungry and purposeful exploration followed by a deep, almost possessive growl.

Cas couldn't remember ever being turned on like this. He groaned into the kiss as he spread his legs to cross them behind Dean, guiding him toward his hole.

Dean drew back for a brief moment, pupils lust blown and lips kiss swollen. "Mate?" he asked as his cock pushed at his hole.

Cas nodded, feeling a little adventurous now that he felt hot all over his body. "Breed me, alpha," he whispered with a lustful moan.

That was met with an ardent growl as Dean pushed inside of Cas, capturing his lips in a feral kiss.

Cas had no idea why he got a kick out of it taunting his alpha, but he really liked it. Something he had been afraid of in his normal day to day life, but here with Dean... he felt like he could do it. Because for some reason he trusted Dean. More than he had trusted anyone before. It didn't make any sense. He barely knew the alpha, but all of their time scenting each other... he learned everything about him on an instinctual level. 

"Fuck," he groaned against Dean's lips, spreading his legs a little further. He would have never thought having an alpha on top of him would feel so exhilarating. He could feel Dean's huge cock sliding deeper than he had ever felt before. "Just like that, yes."

Dean growled again, he scented Cas's neck as he pushed deeper, his enormous knot putting pressure on Cas's hole.

Cas taunted his alpha a little bit more by exposing his neck to him, giving him a lustful look as he moaned, "Fuck me hard, alpha."

With another growl, Dean started slamming into Cas at an animalistic pace, a beast succumbing to his urges as he scented Cas's neck again and then dove in for another kiss, tongue plunging in rhythm with his enormous cock.

It was the first time he had been this passive at sex, but fuck... his alpha really knew how to fuck. All he could do was hold on to his strong arms as Dean fucked his brains out. He was close... so close. "Yes, yes, knot me, alpha, breed me," he growled.

In a whirlwind of movement, Dean shifted, lifting Cas's hips up at the most delicious angle, and suddenly that knot was pushing inside of him.

"Ohhh, fuck!" Cas cried out as he came all over himself as soon as Dean locked inside of him, his big fat knot stretching his inside. It was delicious, the best thing he had ever felt.

The only thing better was feeling Dean's hot seed filling him up.

Dean's breathing was ragged as he nuzzled Cas's neck, his seed pumping him full.

Cas groaned, tilting his head so Dean had more space. "I love when you do that," he purred. "I love feeling your lips on my neck."

"You smell so good," he murmured against Cas's skin.

"You, too." Cas chuckled, feeling punch drunk from all the dopamine flooding his system. "If it was up to me, your nose and mouth would never leave my neck.”

He could feel the reverberations of Dean's soft laugh against his skin. "It would make working difficult."

"Don't burst my bubble, Dean." Cas laughed again, causing him to feel Dean's knot more prominent inside of him. "I can't believe how good your knot feels. My toy sucks..."

"Toys can't fill you with seed," he growled.

Cas could feel Dean pumping more seed into him. Fuck, his knot seriously had a lot of cum for him. He hummed in pleasure. "Yeah, I had problems getting it in, although it's a lot smaller than your knot." He leaned into kiss Dean's throat, licking at the delicious scent gland. "But nothing and no one has ever made me as wet as you have. Just feeling your mouth so close to my scent gland makes me crazy. I don't know why." He knew why. Something inside of him liked to play with fire.

"You have the sweetest scent of any Omega I've met," Dean murmured, another load of seed filling Cas.

"Fuck…" Cas gently rocked his hips up against Dean. "Is that why you can pump so much seed into me?"

Dean nodded. "And I never come as soon as my knot is in."

Cas leaned up to press a soft kiss to Dean's lips. "Does that make me special?" He needed to know. Because although his sexual urges were satisfied for the moment, the Omega in him was still craving the alpha in a different way.

"I think so," he said as he nudged his nose against Cas's cheek.

"Well... you're special to me, too. It's my first time having sex on my back with someone on top of me," Cas confessed, giving him a shy smile that was hopefully enticing.

Dean's eyes widened. "You asked for a submissive alpha." He could smell the panic on Dean.

He quickly clasped his hands about Dean's head, looking at him. "Dean, calm down please. Everything is alright. I pulled you on top and I told you what to do, remember? You didn't do anything against my will."

Dean whimpered against his touch. "You promise?"

Cas quickly pulled him into a deep kiss. "I promise," he whispered, feeling really bad that he had scared Dean. He carded his fingers through Dean's hair. "I... I'm sorry. I should have talked to you beforehand. I just felt so horny and I really wanted to feel you... being all alpha and taking me. I... I'm really sorry, Dean. My Omega took over for a moment here."

"I just don't want to hurt you," he whispered, nuzzling into Cas's neck before scenting him.

Cas started purring, something he hadn't done since he was a teenager. But he needed Dean to calm down. "It's all good, Dean. I know you would never hurt me," he said in a soothing voice. "That's why I trust you with those things. I know your alpha is going to take good care of my Omega, right? Because you're a really good alpha."

Dean drew back, eyes searching Cas's for a moment. "I'll always take care of you."

His heart skipped a beat as he smiled at Dean. "And I'm going to take care of you." He leaned up and pressed a soft kiss to his lips. "And to show you how much I trust you, I would even let you mount me. The traditional way. Although I said I would never do that. But that is just because I have never trusted anyone more than I trust you."

Dean growled before he dove in for another kiss.

Cas chuckled against his lips, as he pulled him down to the mattress with him. "I get the impression that you like that thought, alpha," he growled teasingly. "Do you want to mount your Omega and breed me?" 

That was met with a needy whine as Dean nodded, nudging his nose against Cas's neck again.

Cas exposed his neck for him. "I shouldn't tease you like this. You're still in me," he groaned. "We should cool it down, have a shower together and some lunch. And after that… I'll give myself to you, alpha. I will present for you, so you can mount me and breed me full. With my neck in reach for your lips."

Dean was panting against his neck. "My… Omega."

Cas was getting goosebumps all over his body, softly groaning as he rocked his hips up. "Yes, your Omega," he whispered, enjoying how that sounded. He didn't want to think further than that, happy to stay in his pretend bubble. "And you're my alpha. Mine."

Dean growled again, but this time it was a contented sound as he felt another pulse of seed fill him.

Fuck, Cas loved how much Dean showed that Cas was his. "Dean, you take such good care of me," he murmured before he kissed him deeply and turned them around on the bed. As he laid on top of him again, he gave Dean a soft smile. "Are you hungry?"

Dean hummed. "Yes."

"I meant for food," Cas clarified with a chuckle, dropping a kiss on the tip of his nose. "I wanted to make lasagna."

Dean chuckled. "What's lasagna?"

Cas raised his eyebrows. "I have a feeling it will be something you love."

…. :::: :::: ….

Dean hummed around the gooey cheesy delicious dish Cas had made for them. It was getting easier to use a fork, but this dish was particularly messy, and he knew he had sauce all over his face.

Cas was giving him a soft look before he reached out and carefully cleaned his face with a napkin. "Do you like it?"

"Very much. Can I have more?" Dean still couldn't believe how lucky he had been to find such an endearing and kind Omega.

Cas was beaming at him as he shoveled another big piece on Dean's plate. "I'm glad you like it. Lasagna was the first thing I learned to cook."

Dean dug in, stuffing more in his mouth with an appreciative groan. "What else can you cook?"

"A lot." Cas chuckled as he leaned closer. "And I have a whole year to cook everything for you." He touched Dean's arm. "Is there anything you want to eat? Any wishes?"

"Could…" Dean rubbed the back of his neck and felt weird asking for anything, but he trusted Cas. "Could we have burgers?" The last time he had a burger was at a McDonald's when he was ten.

"Of course. Any specific toppings you like the best?" Cas replied casually as he wiped a piece of bread through the rest of the sauce on his plate.

"Toppings?" He tilted his head. What did that mean?

"Yeah, on your burger. Like what meat, do you like cheese, onion, tomatoes?" Cas licked over his own lips. "I’ll put them on my grocery list."

Dean resisted the urge to lean in and kiss him. "I want to try everything."

Cas reached out to run his fingers through his hair. "Then I'll put everything on that list. I have a feeling you would also love pizza."

"What's pizza?" he asked with his mouth full.

"It's like a flat bread with tomato sauce and meat and vegetables on it and then cheese. It's really good and it's also something where you can choose the toppings," Cas explained before he got up to grab them each a Coke from the fridge.

"Would… would you teach me?" Dean asked, not that it was a skill he would ever need, but he wanted to be able to help Cas if his heat made him feel too weak.

Cas gave him a wide eyed look before he smiled brightly at him. "Of course, I would love to. I’ll get my grocery order out and tonight we will make dinner… burgers together, alright?"

Dean couldn't help but smile. "Thank you."

Cas winked at him before he got on his cellphone and busied himself with the order for a few minutes. "Alright, delivery will be here in two hours. I wonder what we could do in the meantime?" Cas licked over his lips and gave him a suggestive look.

Dean dropped his fork and moved to stand, taking a deep inhale, the smell of Cas's arousal filling his nostrils. He pulled his shirt off and held Cas's gaze. "I have an idea," he growled.

Cas slowly and teasingly slipped out his shirt before he dropped his boxer shorts. He walked up to Dean, nudging his nose against his throat before he said, "Are you going to take care of me, alpha?"

"Always," he purred before he captured Cas's lips in a kiss. And he meant it. He would do anything for his Omega.

When Cas leaned back he gave him a happy and enticing smile before he dragged Dean off to the bedroom. There he climbed on the bed on all fours, presenting for him.

Dean’s cock instantly sprung to life and the sight left him breathless. Again he lost all capability to respond, and crawled onto the bed, diving in mouth first as he lapped up the most delicious slick he would ever taste. He growled when more slick rushed out.

His Omega cried out in lust, and Dean could taste his arousal and need on his tongue. 

The growl that escaped was an echo of his inner wolf, and he slipped a digit in alongside his tongue. 

His Omega's cries were muffled now and Dean could see he was face planting the pillow, his hands clawing at the sheet as moved his hips toward Dean’s tongue. So eager and so needy.

He reluctantly drew back, that delicious slick invading all of his senses. “Mate?” he asked, because despite how needy Cas was, he was a good alpha, and would wait for his Omega. 

"Yes, please, fuck me, alpha, breed and knot me good," his Omega begged, even holding up his thumb from where his head was buried in the pillow.

Dean couldn’t hold back any longer, with his Omega’s permission, he sat up on his knees and started to mount Cas. The heat was intense as he started to sink inside, draping over Cas’s back, his beautiful neck exposed. Dean licked the skin as he pushed in to the hilt.

"Oh, fuck, fuck, yes," his Omega was panting hard before he pushed himself up on his hands, pressing his neck against Dean's lips. "Yes, make me yours," he whined.

He wasn’t allowed to bite, but fuck he wanted to. Instead he kissed the skin, wishing it was his teeth, as he started fucking into Cas like the beast within was howling for.

He could smell his Omega's arousal quickly reaching a tipping point. "Need, need," he cried out.

Dean growled as his hips pistoned in and out, chasing the high of their coupling as his knot finally started to push inside of his Omega. He couldn’t wait to feel him come again. “Mine,” he growled into Cas’s ear when his knot fully popped inside.

He could feel his Omega come, that tight, hot channel clenching around Dean's cock and his knot, milking it, gasping out in lust.

Dean howled as he came, filling his Omega as that beautiful hole milked every last drop from his knot. He exhaled against the nape of Cas’s neck, licking lazily at his scent gland.

Cas groaned against him, leaning closer. "Would you… suck my skin there?" he asked breathlessly. "Give me a hickey?"

“A hickey?” Dean started sucking on the skin anyway, unsure what a hickey was, but feeling his teeth graze Cas’s skin made him pump another load into his Omega.

"Oh, god… fuck, just like that," Cas groaned, squeezing around his knot. "Fuck, I think you can get me to come just from that. Fuck, Dean. You fucked my brains out."

Dean groaned against his neck. When he drew back there was a purpling in the shape of his mouth on Cas's beautiful skin. He growled at the sight, pumping Cas with enough seed it started to seep out. "Fuck…"

"Ohhh, fuck, Dean. Why is that so hot?" Cas growled before he looked over his shoulder. "Let's lay on our side, I can't hold myself up anymore."

Dean grunted as he pulled Cas into his arms, gently laying them both on their sides, still remaining deep inside his Omega. "Like this?"

Cas hummed and leaned back into him. Dean loved that Cas smelled like satisfied Omega. "Dean," he purred. "Sex with you... is just on a whole new level."

Somehow that was still an understatement, he nuzzled Cas's neck. "I've never had sex this good."

“Yeah, me neither,” Cas replied with a soft purr. “And I certainly never presented to anyone before… fuck. I seriously have no idea why that was so hot.”

Dean couldn’t help the growl at the memory of it. He pumped another load into Cas. “You were beautiful like that.”

Cas gasped as he softly rocked back. "Beautiful?" he asked quietly before Cas looked over his shoulder. "When I present for you?"

“Not just that, but yeah,” he said as he pressed a gentle kiss to Cas’s lips.

“So, are you saying you think I’m beautiful in general?” Cas growled teasingly against his lips.

Dean hummed. "From the moment I saw you."

Cas appeared to get lost in Dean’s eyes for a moment. After a long moment he asked quietly, “You really mean that?”

Dean nudged his nose against Cas's cheek. "Yeah, Cas."

A soft smile played around his Omega’s lips. “I actually… think the same about you.”

While Dean was aware he was considered attractive, the way Omegas would look at him like he was a piece of meat… this felt different. Dean pressed a kiss to the nape of Cas's neck. "Thank you," he whispered.

Cas gasped a little before he chuckled. “Oh, man, I had no idea this area could be so sensitive.” He hummed and it was almost a purr. “So, how does the hickey look?”

When Dean saw the purpling skin even darker than before, knowing he was responsible for it, he growled in appreciation. "Like you're mine."

He could see the way Cas smiled wider at that. As if he really liked that thought. It was dangerous to think like this. No matter how good and right it felt, Cas wasn’t his. Would never actually be his. 

Cas hummed in contentment. “When you did that… It felt so good, I nearly came again.”

Dean couldn't help but growl again. He had never liked an Omega's pleasure this much.

Cas looked over his shoulder, his lower lip trapped between his teeth. “Did you… did you think of biting me?” he asked quietly.

"I wouldn't," Dean assured, even though he absolutely did, for the first time in his life.

Cas raised his eyebrow before he reached over and gently cupped Dean’s cheek. “I know, Dean. I’ve told you that I trust you. But… Did you think about it?”

Dean ducked his gaze, and for the first time, found himself incapable of lying to an Omega. "Yes," he said, barely above a whisper.

Cas pressed his finger under Dean’s chin, gently lifting it so Dean would look at him. His blue eyes immediately trapped Dean’s gaze. There was a smile on his lips before he whispered, “I thought about it, too.” He laughed, shaking his head. “It should be a terrifying thought, but… it’s not with you. It’s the opposite really. And I think… it just shows that this between us is really working out well. And that my trust in you is one hundred percent justified.”

Dean flashed him a small smile. This was… very dangerous territory, and the smartest thing to do would be to distance himself from this Omega. Because after a year, Dean would no longer be of use to Castiel, and the last thing he needed was to develop affection for anyone. "I'm glad."

Cas sighed and leaned closer, nuzzling against Dean’s cheek before kissing it. “I think we earned those burgers today. My knees feel like pudding.”

Dean chuckled and finally his knot shrank enough to slip out of Cas's pretty, sloppy hole. He gently patted Cas's ass cheek, "Are you sore? Do you need me to clean you up?"

Cas licked over his lips with a raised eyebrow. “I think we have time for a shower together. What do you think?”

Dean lifted Cas into his arms effortlessly, carrying him bridal style to the bathroom. "I think I like that thought."

Ah, well. He could pretend while he was here anyway.

Chapter Text

Chapter 3

It was strange, as though there were a phantom itch he couldn't scratch. Dean cracked his neck and lifted his fist to knock on the door of… Dean looked down at the slip with the name and address. This client wasn't in heat, but was in need of mating for purely sexual gratification. Lisa Braeden.

Dean cleared his throat and put on a plastic smile.

When Lisa opened the door, Dean was struck by two things, one, her sheer beauty, and two… her scent. It wasn't often that Dean was paired with an Omega who's scent wasn't pleasant, but it did happen. 

Proud of himself for not crinkling his nose in disgust, he flashed her a smile. "Are you Lisa?"

She nodded, holding the door open for Dean. "Yes, you must be from the service."

Dean nodded as he stepped inside a quaint but nicely decorated house. Everything was exceptionally clean, he was almost afraid to sit anywhere.

When he turned back to face her, she had disrobed completely, stark naked and eyes raking over Dean's form with an obvious hunger.

"No talking. Get naked." Lisa said as she went right for his belt.

Again, with a forced smile, Dean stripped his shirt and as she dropped to her knees in front of him, all Dean could think of was Cas.

But then she suddenly halted her movement and wrinkled her nose. She looked up at him in confusion, slowly getting up. "You reek," she didn’t say as much as she accused.

Dean's eyebrows shot up. That has definitely not been a common occurrence either. "I apologize."

She gave him a disgusted look. "I thought your agency only had clean alphas."

"I am clean." Dean said, brow furrowed. "Occasionally we get scent marked by other clients, but we are all clean."

She gave him a bitchy, skeptical look. "I can't do this. I will need another one."

That was definitely a first. He started pulling up his pants. "Contact the agency, they will send a replacement shortly."

Lisa nodded, wrinkling her nose again. "Get out, I don't want you to stink up my apartment."

Dean nodded and gladly stepped outside. The angrier she got, the worse her scent became. He let out a relieved exhale as he started his trek back to the agency. 

Fuck. If he still smelled like Cas after a couple of weeks, he was going to need a full scrub down.

…. :::: :::: ….

Cas had made it a thing to always cook something with Dean when he was over for their scenting sessions. 

He would usually take a few deep inhales before showing him how to cut vegetables, stir sauce and not let anything get burned. It was a lot of fun, teaching Dean to cook, who was an excellent listener. Today they had planned to make pizza, which had turned out to be one of Dean's favorites. 

He loved the playfulness between them, scenting each other, while cooking. Enjoying the domestically of it all.

But this time it was different. When he opened the door for Dean, Cas's nose was insulted by a sickly sweet smell. He recoiled as his eyes widened, his stomach felt like it was turning. "What… what happened to you?"

Dean sighed. "Shit, I smell bad to you, too?"

He couldn't help the growl falling from his lips, his heart suddenly started aching. He touched his chest in confusion. "Fuck," Cas pressed out. It was hard to breathe suddenly and he stumbled backwards, bracing his hand on the backrest of the couch with a pained groan. "You were with someone else," he whispered. Of course Dean had been with someone else. It was his job. Cas knew that. Why did it hurt all of the sudden? "I smell… her," he growled.

Dean was instantly at his side. "I wasn't… she sent me away because… she could smell you."

Cas held his hand in front of his mouth and nose, shaking his head. "I'm so sorry, Dean. I feel so dumb for my reaction." He grabbed Dean's wrist and pulled him to the bathroom. "Take a shower with me, alright?" He needed to get that smell off of his alpha. 

Dean started stripping his clothes. "I'm sorry."

"It's not your fault." Cas cupped his cheek and gave him a pained look. "I'm just…" He shook his head as he started the water and stripped his clothes. "It's my stupid biology, so please forgive me."

Dean sat against the sink, his head down and shoulders slumped.

Cas was quickly undressing himself before he pulled Dean under the shower with him. "Come here," he said softly. "Everything will be fine." He hated seeing Dean so devastated.

"You can't know that, if I smell bad… I'll have no use anymore."

Cas shook his head. "The smell of that bitch," he growled, shocked at himself for this severe reaction. "We'll wash it away." He opened one of his shower gels and started to spread it over Dean's body. "Your scent is still there. Just buried."

Dean raked his hand through Cas's hair. "What if I'm broken? I won't be able to help you."

Cas could practically smell the distress and worry on Dean. He hummed, rubbing the soap over his scent glands before he pulled Dean close, rubbing his nose over it. "You're not broken, Dean," he inhaled deeply, Dean's beautiful scent mixed with the showergel. He couldn't detect that other Omega anymore. "Don't be afraid," he groaned as he pulled Dean into a tight hug, the water rushing warmly over them like a blanket. "Scent me."

Dean's face buried in the crook of Cas's neck and he took a long, deep inhale. He hummed. "She smelled so bad, I was glad she sent me back."

Cas exhaled slowly. Dean's words appeased his inner Omega. "I know, I have no right to… say anything, but I'm glad you didn't sleep with her."

Dean looked at him, expression stricken. "What happens the next time? Will… will you send me back?"

"What?" Cas gave him a shocked look. "Of course not… I feel ashamed for getting upset and I know I will get upset the next time, but… there is no one I want other than you. We'll make it work."

"You promise?"

Cas gave him a warm smile. "I promise." He reached out to card his fingers through Dean's wet hair. "Do you think… that there is a way I could book you exclusively? We can't be the first… um, pairing with this kind of problem. You know, with people who are scent compatible."

Dean shrugged. "I know there's been some cases, but as a rare alpha… I'm not sure."

"Maybe I should ask my doctor. I don't think he intended that I'll suffer side effects like this. Not if they can easily be avoided by you not seeing other Omegas," Cas wondered out loud.

"Yeah, I don't want to cause you any bad effects," he said softly.

“I know you don’t.” Cas carded his fingers through Dean’s wet hair, giving him a soft smile. “None of this is your fault. So, please don’t worry. I will take care of this situation, alright?” He leaned in to press a soft kiss to Dean’s lips. “I promised you that I will take care of you.”

Dean held his gaze for a seemingly long moment before he cupped Cas's cheek. "You're the kindest person I've ever met."

Cas gave him a pained look. "That's actually pretty sad. I'm not… in any way special." He knew a lot of kind people.

"Yes, you are," Dean said, a small smile curling his lips.

"That's very sweet of you to say, Dean." Cas rubbed his thumb over his cheek before he shut off the water. He pulled Dean out of the shower and wrapped him into a fluffy towel. "Let's spend the rest of our time in bed and I'll phone the agency and my doctor later to see what my options are."

Dean cupped Cas's cheek and dragged the pad of his thumb across Cas's bottom lip. "Thanks, Cas."

Cas's breathing hitched at the intimate touch, his lips tingling as he felt himself suddenly getting wet between his legs. "Um, yeah, no problem," he breathed out, slowly rubbing his skin dry on his own towel.

Dean's nostrils flared and he let out a contented sigh. "Fuck, I love your smell."

Cas squirmed in his towel, a soft whine falling from his lips that was impossible to hold back. He stepped closer to press his nose against Dean's throat, desperate for his scent that immediately calmed his nerves. He could feel slick running down his leg as he inhaled deeply. "Now you're smelling like you again."

With a soft growl, Dean craned his neck to scent Cas back. "Thank you for saving me," he whispered against Cas's neck.

"From what?" Cas gasped, melting against Dean as he slowly guided him to his bed, losing the towel on the way.

"From becoming useless," he said softly as he crawled onto the bed, bracing his arms outstretched along the headboard, in clear invitation. His knot was hard and at attention.

Cas slid into his arms, pressing his nose against Dean's throat as he slid his palm gently over Dean's chest. "You will never be that," Cas growled and he hated that Dean had that fear. "No matter what anyone says." He put his leg over Dean's to be even closer to his alpha. Fuck , seeing Dean's knot had resulted in more slick running out of him.

Dean nuzzled his nose against Cas's cheek with a soft hum. "I know you want these sessions just for scenting, but I'd love to taste your slick again."

"Fuck," Cas gasped out, squirming against Dean. "If you lick me, I'm going to lose it and will want more."

Dean's hand carefully raked through his hair. "I'll do whatever you ask."

"Dean," he complained softly. "I can't. This is an extra service and you mean more than that to me. I don't want to use you."

Dean held his gaze for a moment. "I wasn't offering a service."

Cas stared at him for a moment. "Are you asking to have sex with me… just for fun?"

He could instantly smell the insecurity on the alpha. "I'm sorry, I shouldn't have suggested…"

Cas pressed his finger to Dean's lips to hush him. "Are you sure this is what you want and you're not just offering because… I scared you when you got here?"

Dean pressed a kiss to his finger before he drew it back. "I want you."

Cas's heart skipped a few beats before he pulled Dean in for a kiss, crawling into his lap. "I want you, too. So much," he breathed out as he guided his slick hole against Dean's cock. "How do you want me?" 

"Like this," he breathed out through a growl. "Love watching you ride me."

Cas hummed as he moved his body over Dean. He reached back to spread his ass, guiding his wet hole against the head of Dean's cock to tease it. He groaned at the delicious teasing pressure of Dean's hot skin against his own, threatening to push inside. His slick ran over Dean's cock as a new wave of lust ran over him.

"Beautiful," Dean gasped out, eyes locked with Cas's.

Cas smiled softly at Dean, the compliment giving him a funny feeling in his stomach. He carefully lowered himself, feeling the fat and blunt head of Dean's cock breaching him. Fuck, it felt glorious. He loved how big Dean was and that Cas was able to take him. Not being wet enough was finally a problem of his past.

Dean let out an animalistic growl, and when he looked Cas in the eyes, there was an impossible hope shining in them. "Kiss?" he asked timidly.

Instead of verbally answering, Cas bent forward to draw Dean into a deep kiss, all while he sank further down on Dean's cock. When he finally bumped against his knot, he needed a few moments to get used to Dean's girth, happily licking over his tongue in the meantime.

Dean's hands were in his hair, kissing back like a man getting to breathe for the first time. Cas could feel the possessive growl that escaped Dean's chest.

The growl pushed him to slick even more, his hips started to move on their own. The pressure on his prostate was maddening. He groaned against his lips before he leaned back and presented his throat to Dean, hoping he could feel Dean's teeth against his skin. Just the thought almost made him come.

Dean scented him, his lips pressing fevered kisses along his pulse point. And then he felt his tongue snaking out.

"Oh, fuck, yes, Dean, please," Cas started to fuck himself on Dean's cock, harder and faster. Dean's length sliding in with ease from all the slick. The pleasure was off the charts and Dean's lips on his throat felt like an infinite orgasm.

And then, to Cas's surprise, he sucked the sensitive skin between his teeth. Dean was giving him another hickey.

Fuck. "Please, knot now!" Cas cried out. He wanted – no, needed – to come on Dean's knot.

Dean's expert hands guided Cas slowly, using his slick to loosen his rim, and that magnificent knot started pushing inside.

Cas groaned loudly as it finally slipped in the rest of the way, locking Dean's cock inside of him. That in combination with Dean's tongue licking at the hickey pushed him right over the edge. His come painted Dean's chest and stomach as he groaned out, "Fuck, yes, alpha, yes."

Dean growled as he filled Cas, then licked the mark as though to sooth him.

It was an alpha instinct. They usually licked bites so they wouldn't get infected and Cas had no idea why that thought made him giddy. Probably the high of his orgasm. "Dean, you're making me crazy."

Dean hummed. "Should I stop?"

"Fuck, no," Cas replied with a satisfied hum before he pressed a soft kiss to Dean's lips. "You're amazing, do you know that? I love when you give me a hickey."

"I've never done anything like that before," he said softly.

Cas braced his palm on Dean's broad chest as he sat up to look at him with a smile. "I have to confess that I'm relieved to hear that." He sighed softly, looking down. "I'm sorry. I feel like I'm constantly crossing a line with you. It's just… that I really like you."

Dean braced his own hand over Cas's. "Me too."

Cas gave him a soft smile. “Please tell me if I say something inappropriate, or make you uncomfortable.”

Dean let out a soft laugh. "I don't think you could."

Cas tilted his head, his smile turning into a grin. “Inias often tells me that subtlety is not my forte, and I can be very blunt and tactless sometimes.”

"I'm sure it doesn't mean much coming from an alpha, but I like that about you."

Cas bit down on his lower lip, carding his fingers through Dean’s soft hair. His heart hurt and he knew why, although he didn’t want to think about it. “It means a lot coming from you, Dean.”

Dean pressed a gentle kiss to his lips. "Thank you. For being so good to me."

"I hate that isn't normal for you," Cas admitted after a moment, pressing his forehead against Dean's. "I wish it was."

"The time we get together I get to be normal, and I'll treasure that for as long as I live."

With a heavy heart Cas bent down to press another kiss to Dean’s lips. The thought of having a deadline on this… It was something that broke his heart. And he wondered for the first time if there was anything he could do to change that.

…. :::: :::: ….

Dean let out a shaky exhale as he looked at the boring, seemingly innocuous wooden door for his next client. An Omega in need of heat relief. He felt dirty, and wrong in his skin. 

Cas had tried to book Dean exclusively, but his insurance wouldn't cover it, nor was the agency willing to give up the exclusivity of a rare alpha. He wasn't always booked, but when he was, they made three times as much in one session than in a week for a regular alpha.

It was devastating, especially considering Dean wanted to help Cas, not make things worse. And it was the first time in his existence he genuinely looked forward to his times with an Omega.

Ketch gave him shit for it, and Benny called him a lovesick pup, but Dean didn't care. Cas was the first Omega who was genuinely kind to Dean, and the first Omega he had ever had sex with without reporting it to the agency for reimbursement.

Dean knew it was dangerous to have these thoughts, but he couldn't help how he felt. This longing, this almost need.

The door opened and a beautiful, dark skinned Omega in his early thirties looked up at Dean in surprise. "You're prettier than your picture."

With a forced smile, he said, "You must be Max?"

Max smiled and invited Dean in.

He didn't smell as bad as Lisa, but he didn't smell great. Shit, maybe Dean was broken…

Max scrunched up his nose. "Damn, we're not scent compatible…" He looked Dean up and down. "And that sucks because you're fine."

Dean sighed and ducked his gaze. "Would you like me to leave? The agency will send a replacement."

The Omega looked thoughtful at that. "I… I don't know." He leaned closer to take another careful whiff. "Oof. I'm not sure if I can tune that out. Are you the only alpha there that isn't dominant?"

Dean shook his head. "There's three of us."

"Are they all as good looking as you are?" Max asked, trying to look flirty, but the way he scrunched his nose wasn't a good sign.

Dean couldn't help but chuckle. "I want to say yes?" He took a step back. "I'm sorry, I even scrubbed extra hard." Parts of his skin were still kind of red.

"Well, It's not your fault. If our scents aren't compatible, that's just bad luck." He shrugged. "I'm a biology teacher. There is a lot of misinformation about scents out in the public. Did you know that you will only smell good for someone if you're genetically compatible? It's to ensure that the mating will work. And even though it happens rarely, if an alpha finds an Omega that is one hundred percent compatible, the scent changes and they will only smell good for that Omega and no one else. So yeah, you smelling bad to me is only our biology warning that we don't fit together, no matter how clean you are."

Dean was at a loss for a moment. He didn't know any of that. "What… what happens if an alpha's scent changes?"

Max gave him a sad look. "Like I said, it's rare, but there are cases. If the Omega that alpha is tied to wants it, they would have a great chance to buy the alpha as personal property. Because usually the Omega is affected by it, too. And in our society, it's Omegas first." The last sentence sounded a bit bitter.

"And… if he doesn't want to buy the alpha?" The giant rock formation building in Dean's stomach told him he already knew the answer.

Max looked uncomfortable as he replied, "I'm not sure, but working this job would be impossible."

Dean nodded, and flashed Max a forced smile. "If you contact the agency, they'll send someone else," he said as he made his way to the front door.

"I'm sorry. I hope you're not worried about the scent thing. Like I said, it happens rarely. Only with true mates," Max explained as he walked Dean to the door.

True mates were rare, so maybe Dean was just having a bad streak. "Well, thank you for being kind. It shouldn't be too long for my replacement to get here."

Max gave him a sad nod. “Yeah, no problem, man. It’s a shame, seriously. But what can you do?” He shrugged and winked at Dean before he opened the door for him. “Good luck.”

"You too," Dean said as he started the trek back to the agency. He really hoped that it was a bad streak, because if Cas and he were true mates, that would mean Dean would become useless and sent back to alpha camp for retraining.

Yeah, it had to just be a bad streak.

…. :::: :::: ….

Cas pressed his nose against Dean with a soft sigh, inhaling deeply as he relaxed against his alpha. They had to take a shower again because Cas could smell another Omega on him and it irked him that his nose was so sensitive. It was more than that though. Cas felt jealous and it bothered him a lot.

He sighed again, nudging Dean’s scent gland with his nose as he murmured, “I wish I could keep you here.”

Dean pressed a kiss to his forehead. "That the heat talking?"

"No," Cas murmured tiredly, before he licked at Dean's throat with a soft moan. "I'm selfish. I just want to keep you for myself and I'm still angry your agency is so... ugh."

Dean let out a soft laugh. "At least we get these days together." After a beat he nudged his nose against Cas's cheek. "Can I ask you something?"

“Of course,” Cas replied, looking up at Dean before pressing a soft kiss to his lips. He let his hands wander over Dean’s warm skin, enjoying their closeness.

"Do you think… uh, true mates exist?"

Cas raised his eyebrows in surprise, wondering why Dean was asking about that. "Um, yes. I think there is enough scientific data made about that phenomenon. It happens on rare occasion. Why… why are you asking?"

Dean flashed him a reassuring smile. "Just something the, uh… the last Omega said. We were, uh… we were always told it's a myth."

Cas felt a sting of jealousy again. He squinted his eyes at Dean. "Why did that Omega talk to you about true mates?"

That was met with a soft chuckle. "We weren't scent compatible either, and he said he teaches biology and kind of explained how that works."

Cas's inner Omega felt soothed by his reply. "Yeah, it's very rare. Omegas and alphas who are true mates change their scent, so it's clear that they were made for each other. The scent will make it clear they are off the market."

Dean hummed. "You'll be honest if I start smelling bad to you too?"

Cas had to laugh at that. “Dean, you smell like Heaven to me.” He furrowed his brow. “Is that… Are you worried about your scent changing?”

"I know that can only happen for true mates, but I've…" Dean ducked his gaze. "I've never smelled bad to an Omega before."

Cas felt a little confused about the conversation. “Dean, you don’t smell bad to me. And I am an Omega.”

Dean nodded. "I know, but the last few times I've been hired… I get sent back."

He couldn't really say that he felt bad about Dean not having sex without anyone but him, but his rational brain could see how this was problemetic. "Look, if you really have met an Omega who is your true mate, you would also smell bad to me. And you really don't, Dean. I can assure you. And seriously, you have no idea how rare it is to meet this person. I'm sure it's just... bad luck." Or good luck for Cas’s totally inappropriate jealousy.

Dean flashed him a small smile. "I'm sure you're right. You're much smarter than me."

Of course there was this little thought nagging his brain. The thought that he wanted to be Dean's true mate. It was ridiculous. Dean was an alpha. There was no way that this could end well. He would only get his heart broken, so it was nothing he should wish for. 

"You know, the Omega's scent will change, too, if something like that happens," Cas replied after a long thoughtful moment. "So it wouldn't just be you. If you're really worried about this kind of stuff, I could do some research into the matter and see what alphas can do if that happens."

Dean gently cupped Cas's cheek. "You continue to be so kind." He leaned in for a gentle kiss.

Cas turned them around on the bed, pulling Dean on top of him as he deepened the kiss and spread his legs. "I don't want you to worry," he murmured against Dean's lips. "You... you're very important to me."

Even though Dean smiled, it didn't quite reach his eyes. "Would…" he licked his lips. "Would you still…" Dean shook his head and nuzzled his face in the crook of Cas's neck.

"What is it, Dean?" Cas softly prompted him, carding his fingers through his hair.

"I know you won't need me anymore, but I… I was hoping you might still want to… hire me. Even after…" he confessed.

Cas stared at him, for a moment forgetting how to breathe. "Is that something you really want?"

Dean's lips curled up in a smile as he caressed Cas's cheek with the pad of his thumb. "I'd just hate to never see you again."

Cas swallowed dryly. He wasn't sure what to think. He was paying Dean to have sex with him. What if this was only a sale's pitch? He couldn't see any reason why Dean would want that. He searched Dean's eyes before he grabbed his cheek, his light stubble feeling nice against his palm. "Why?" he finally croaked.

Dean turned his face to kiss Cas's palm. "Because you're important to me too."

The way his heart skipped a few beats and butterflies stormed through his stomach made him realize how much he had wanted to hear those words. "I... Yes, I want to continue seeing you. Even after."

Dean let out a relieved laugh before he drew Cas in for a tender kiss.

Everything felt warm in his body and Cas felt a sudden surge of need. Not caused by his heat, but from the sheer fact that he wanted to be close to Dean. He crossed his legs behind Dean's ass, pushing him up into the right position to enter him again. "Dean," he whispered softly. "Take me. Make me yours." He knew he shouldn't say those things. But he wasn't kidding himself. He was lost. 

Dean growled as he scented Cas, shifting his hips to slowly slide his cock inside again. "Mine," he growled.

He knew he could still get away with this probably being a popular kink. Not that they had ever talked about it, but Dean just played along, so Cas guessed that he was okay with it. But that was the big problem, right? He didn't really know. He didn't know how much of this was Dean being a professional, or what he was really thinking. And here Cas was, playing house with an alpha, because he felt lonely and pathetic. 

He knew his scent must have changed to distressed when Dean stopped moving on top of him. Cas looked away, ashamed of his stupid emotions, making a mess of him.

"Cas?" Dean asked as he cupped his cheek.

"I'm sorry, Dean." He couldn't help the tear running over his cheek and angrily wiped it away. "I don't know what's wrong with me. My emotions are all over the place."

To his surprise, Dean gently pulled out of him. He wiped away the tear from Cas's cheek. "Can I help?"

Cas took in a shuddered breath, biting his lower lip before he looked up at Dean. "I... I would like to know... how much of this is real for you, and how much is just you doing your job? I know I shouldn't ask you. I just need you to be real with me. Because I can't... I need to know."

Dean furrowed his brow, expression almost stricken. "I… I don't feel like I'm working when I'm with you."

"So... you really mean those nice things you say to me?" Cas asked hesitantly. "That... you want me to be yours?" Fuck. What the hell was he doing? He would totally understand if Dean stood up and left him forever at this point.

"If… if things were different, I… yes, Cas. I wish you could actually be mine."

Cas got lost in Dean's eyes for a moment. His breathing hitched as he gave Dean a pained look. "I... I feel the same, Dean. And I know... it's impossible, but it doesn't change that you're the only thing on my mind and... how jealous I get when you're with other people."

"Are… are you sure you're not influenced by your heat?" Dean sounded so scared, so insecure.

Cas cupped Dean's cheek and nodded. "I feel the same outside of my heat. I know I'm being stupid... and I bet this happened a lot to you... shit, you must think I'm pathetic."

Dean leaned in for a soft kiss. "I don't. I think you're beautiful."

"Dean," Cas whispered as he drew him into a deeper kiss. "Fuck, I need you so much."

Dean hummed and shifted his hips, gently guiding his erection to Cas's hole again. "Yes, need," he growled.

Cas used his legs around Dean to push him inside. His cock impaled him easily, still being relaxed and open from the last time. He pulled Dean into a deep kiss when he felt his thick knot at his rim. Fuck, he felt like he was going crazy with want and need. He offered his neck without thinking about it, instinctively, whispering a broken, "Please."

Dean scented him, his tongue darting out to lick and suck along his gland as he started slowly fucking into him.

It was driving Cas insane. “Fuck, fuck, yes, Dean. Just like that. I wanna feel your teeth, baby, please.”

Dean's growl turned almost primal as he scraped his teeth along Cas's pulse point, never once breaking rhythm.

"Oh, fuck," Cas cried out as he suddenly came all over his body. Feeling Dean's teeth had pushed him right into an orgasm. "Alpha, please. Knot me."

Dean grunted as one of his hands slipped between them, massaging Cas's rim as he started pushing the knot inside. "Mine," he growled as his knot slipped inside, locking them together.

"Yes," Cas groaned as he enjoyed the immense pleasure Dean's thick knot was giving him. "I'm yours, Dean. My alpha." He leaned up to draw him into a deep kiss. 

Dean hummed into the kiss, settling against him as he continued to fill Cas. "My Omega."

Cas licked into Dean's mouth with a soft groan. "Do you like breeding me, alpha?" he asked, enjoying the playful dirty talk.

Dean simply growled again, another hot pulse filling him. "Breed…"

"Tell me," Cas growled softly. "Tell me, how much you want your seed to catch." He really wanted to turn Dean on, filling him with so much seed it would flow out of him.

Dean whined, a soft sound that still had a growled undertone. "Want… to breed you… to mate…"

"Yeah," Cas nudged his nose against Dean's throat. "You're doing so good. Fill me with so much of your seed. My mate."

Dean drew back, eyes wide. "Mate?" His eyes drifted to Cas's pulse point, his hand resting at the nape of Cas's neck.

Cas gave him a soft smile, his heart in pain. "I know I can't have you like that, but... I want you. I want you so much, Dean."

"Me too," he breathed out, barely above a whisper.

Cas carded his fingers through Dean's hair, drawing him into a deep kiss. "Then let's pretend alright? When it's just us... that we're together. That you're my mate."

Dean flashed him the sweetest smile. "You make me happy, Cas."

"I'm glad." Cas mimicked the smile, getting lost in green pools before he added a soft, "Mate."

Dean dove in for another kiss.

Cas rocked his hips up against Dean's body, enjoying the stretch of Dean's knot as he licked over Dean's tongue. A few open mouth kisses as he hotly breathed out, "Can you please... I want to feel your teeth again."

Dean grasped Cas's wrist and drew it to his lips, he pressed a playful bite to his wrist pulse point.

"Dean," Cas whined, his hips rocking up, squeezing Dean's knot before he presented his neck. "Here, please."

He could feel the heat of Dean's breath against his neck before those teeth grazed his skin. Dean started sucking at his scent gland, teeth leaving tiny bites.

Cas was losing it under Dean, moaning loudly as he wrapped his arms tightly around Dean's back. "Fuck, Dean. This feels so good and right."

Dean gasped against his neck. "Cas… I… I want…"

Cas groaned, wondering if Dean wanted the same thing. "Tell me," he breathed out with a soft moan.

Dean drew back. "I want to bite you," his voice was broken and scared.

Cas's breathing hitched before he leaned up to draw Dean into a deep and loving kiss. "I know. I want it, too. So much." He nudged his nose against Dean's neck. "I'm sorry that I'm making this hard for you. I... I keep presenting my neck to you. I shouldn't do that."

"If things were different," he growled softly, "the world would know you're mine."

Cas couldn't help the smile. "Yes, I would proudly wear your mating bite, Dean." He pressed a soft kiss to Dean's lips. "But this is our little world here. And in here you're my partner, my mate. Bite or no bite. I only belong to you."

Dean carded his hand through his hair. "I wish I could steal you away."

Cas laughed at that, leaning into Dean's palm. "I actually wish the same. I wish I could just keep you. With me… forever."

Dean sighed. "The only way that could happen is if you bought me."

“Bought you?” Cas asked with raised eyebrows. “Is that even possible? I mean, I couldn't even get the agency to give you to me exclusively for this year.”

Dean shrugged. "The biology teacher mentioned it. I don't know… I've never heard of it, but most used alphas aren't wanted…"

Cas chewed on his lower lip. He knew theoretically that an alpha could be purchased. Some people could get a special license to keep one. It was mostly decided through the court system. "I know that it is possible. To buy an alpha as a private person and not a company. But there have to be special circumstances. The problem is that you already are the property of your agency. And they wouldn't just sell you to me for no reason. I know I can't go to court, trying to get a license just because I have feelings for you."

Dean sighed, flashing him a sad smile. "I wish I wasn't an alpha."

Cas sighed and nodded. "That would make things easier, but on the other hand, as an Omega or Beta you wouldn't be able to help me through this hard time." He rubbed his thumb over Dean's beautiful freckled cheek. "I'll research my rights and what we can do in our situation. Don't worry, I won't give up easily."

Dean's eyes were shimmering with unshed tears. "If only we were true mates."

"That would probably make things easier in court," Cas replied before he sighed. "I haven't noticed my scent changing though. At least no one has mentioned anything to me." Cas rubbed his chin thoughtfully. "On the other hand, I worked a lot from home this week and I haven't seen Inias in a while."

Dean tilted his head. "Should we call him?"

Cas gave Dean a soft look. "I don't want you to get your hopes up. If we call him and I let him scent me, he would definitely know if it has changed. We're very attuned to each other, but… if it hasn't changed…" It was a nice dream, but very unrealistic.

"Maybe it's just wishful thinking." 

Cas pressed a kiss to Dean's lips. "That's very possible. But true mates or not, this doesn't change my feelings for you."

Dean smiled and carded his hand through Cas's hair. "Do you know what love feels like?"

"Now I do," Cas replied softly, pulling Dean closer. 

Dean gasped, nuzzling against his cheek. "Tell me?"

Cas pressed his lips to Dean's temple. "Like you're breathing easier when the person is around. You sleep sound to their heartbeat. They're the first thing on your mind when you wake up, and the last before you sleep and when they are not there… your heart hurts and longs for them to be close, counting the minutes and hours until you're reunited." Cas's kisses wandered down to Dean's throat, licking carefully over Dean's scent gland. "You make my heart race with just a smile, you make me forget to breathe when I look at you."

Dean's hand twisted in Cas's hair, a gentle yet firm grip as he arched his neck for Cas. "That you feel a pleasant tingling when you feel their lips on your skin. And for the first time, your heart feels full?"

Cas softly bit the skin around Dean's scent gland. "Yeah," he growled. "That, too."

Dean turned his face to capture Cas's lips in a hungry kiss.

Cas moaned into the kiss, loving the feeling of Dean's tongue sliding over his own. Dean's knot was still thick, locking him in place, and Cas hoped he could make Dean come again. "My alpha," he purred, as he bit Dean's lower lip. 

"I think I love you, Cas," Dean gasped out.

Cas's heart skipped a beat, finally hearing the words he had been longing for. He clasped Dean's cheeks to look at him. "I love you," he murmured. 

Dean nodded, pressing a tender, yet lingering kiss.

Cas sighed against him, his fingers sliding through Dean's hair before he leaned back. "It's hard, every instinct in me wants you to bite me."

Dean braced his palm at Cas's pulse point. "Every instinct in me wants to."

Cas groaned, loving how his hand felt there. "Fuck. It just feels so right. I love you, I want to be your mate. It's so dumb that we aren't allowed to do it."

Of course Cas knew why it was forbidden. There was actually a really good reason behind it. Before it had been forbidden, alphas had bitten Omegas against their will, forcing them into only being able to mate with that one alpha. It was a sign of ownership. A mark of slavery for most Omegas nowadays. Cas had thought so, too. 

But it was different now. Because this was a consensual longing to belong to Dean. To be his mate. "It drives me crazy when you touch me there, when I feel your lips… ugh, your teeth. It made me come untouched."

"You're so beautiful when you come," Dean breathed out.

Cas shook his head. "Dean… how can we make sure it doesn't happen accidentally when we both want it so much? I don't want you to get in trouble. I mean, I could wear a scarf until it's healed over, but… there would still be the scar after and that's nothing I could hide forever. At some point people would ask questions and… I don't even know what would happen then." He knew he was rambling, but he was really concerned about Dean's wellbeing.

Dean's breathing came out in growled pants. "I… I can… be good. A good alpha…" 

“I know. I’m not worried about your resilience,” Cas breathed out, his lips sliding over Dean’s in a featherlight, open mouthed kiss. “But I want you to bite me so much.”

"Why?" Dean gasped as he started peppering kisses along Cas's jaw and down his neck. Kisses that turned into a slight grazing of teeth.

It drove him crazy and he writhed under Dean, arching his body against him. “I don’t know,” he breathed out. “Your teeth feel so good.” He hummed softly, presenting more of his throat to Dean. It was probably a biological, hormonal thing.

Dean drew back, his expression serious. "I'm yours, I will do whatever you ask."

"I would never ask something of you that would get you in trouble." Cas stroked gently over Dean's cheek. "I wish I knew more about the law. But when my heat is over, I will contact a lawyer and will find what we can do. Maybe there is a possibility I could... that we could be together."

Dean's eyes lit up. "Really?" He sounded so hopeful.

"I promise you." Cas smiled at him before leaning up and pressing a soft kiss to his lips. "When your knot goes down... maybe you want to bite me a little on my inner thigh?"

Dean growled appreciatively. "Yes."

"You like that?" Cas asked teasingly as he nudged his cheek with his nose. "It wouldn't be a mating bite. But you would mark me and it's only for me to see."

Dean's breath was ragged as he dove in for a frantic kiss.

Cas laughed against Dean's lips as he grabbed Dean's face to hold him back. "If you get too excited your knot will never get down, baby."

Dean let out a ragged laugh. "You make me crazy sometimes."

"It's the same for me, Dean." 

His heat would last another two days. So Cas was incredibly happy to spend all that time with Dean before the real world would have them again. But maybe it wasn't all so bleak. Maybe there was hope for them.

.... :::: :::: ....

Dean was buttoning up his flannel, getting ready for another heat call, when this sudden, overwhelming need made his blood start to boil. He gasped and clutched onto the footboard to his left.

Garth jumped up and looked at Dean in clear concern. "Dean, you okay?"

For some reason, he was really struggling with how to work his tongue to answer him. He held Garth's gaze when his cock started coming to life. "I… No."

Garth sniffed the air around him before he recoiled. “Dean, did you forget your blockers?” His voice sounded alarmed. “You’re going into rut!”

"No, I… I took them," Dean managed to growl, his grip tightening on the wood, he could feel splinters piercing his skin. 

This couldn't be rut. It had been years since the agency doctor changed his prescription. "Not… rut."

In that moment Ketch opened the door and immediately recoiled, nose turned in disgust. "What on bloody earth is that?"

“Dean is going into rut. We need to call someone, quickly,” Garth said as he pushed Ketch to the door. “Go! I’ll stay with him.”

Ketch disappeared, the door slamming shut behind him.

Dean approached Garth. "Cas… Cas needs… soon." His thoughts were becoming fuzzier, the need was getting stronger, his skin was practically burning.

"Cas? Your favorite client?" Garth asked in a soothing voice. "What about him? Concentrate Dean. Tell me about him."

"Cas… heat soon…" Dean growled, his hands were starting to shake. And all he could think was how he wouldn't be able to be there for Cas. When Cas needed him most. A hot tear rolled out of the corner of Dean's eye. "Need. Love."

Garth held up his hands, but he wasn't coming closer. "Hey, Dean. Everything will be okay, alright? You will get over this in no time and then you can go back and help Cas. Don't worry."

The sound that escaped was a whimper, and everything was getting fuzzy. "Cas," he growled as he stepped closer to Garth.

Garth backed away from Dean. “Dean, stay calm. Please. Everything will be fine, alright?”

Anger washed over him then, why wasn't Garth listening. He slammed his fist into the wall, the shitty plaster crumbling. "Cas!"

"Yes, Dean. I know." Garth stepped back as the door opened and Ketch was back with two Beta guards. 

Dean growled and crouched down, baring his teeth. Cas needed him. Why weren't they listening? "Cas… tiel. Needs me."

The guards were approaching. Dean knew them. They weren't very kind. One of them was holding a taser, the other one was holding handcuffs. "Hands to the front!"

"Cas," Dean growled. He was going to do it, he had to. For Castiel.

Dean snarled and dove for asshole number two, right for the taser.

The other one radioed for additional support as he grabbed Dean’s arms from behind, pulling them back, while the other rammed the taser against Dean’s chest.

The pain was excruciating, and before his vision blacked out, all Dean could think was: what about Cas?

Chapter Text

Chapter 4

Cas had to sit down to digest everything the friendly lawyer had told him on the phone. It was a lot. It turned out that he had the right to purchase an alpha (which wasn’t cheap, but he would manage), but it was bound to a lot of stipulations and things he had to prove. 

The lawyer had asked him if they were true mates and Cas had replied in truth. That he didn’t know. And there was the crux of the matter, how would he find out? If they weren’t true mates, he couldn’t buy Dean and he would have nothing. 

There was only one thing he could do and that was talk to Inias. He probably would tear him a new one when he confessed that he had fallen in love with an alpha. 

Cas sighed and rubbed his palms over his face before he walked over to Inias’s apartment. Thankfully he was home tonight, although his friend looked a bit tired. He hugged him before he gave him a puppy eyed look. “I… I have a big problem.”

Inias furrowed his brow as he guided Cas inside. "What's going on?"

Cas guided them towards Inias's couch. "I... oh man, you will think that I'm the biggest idiot." He sat down, pulling Inias next to him. "So, Dean... um, the alpha, who I'm seeing... I... I fell in love with him."

Inias's eyebrows shot up. He braced his hand on Cas's forehead. "You don't feel feverish."

Cas playfully swatted Inias's hand away. "I'm serious, Nias. And the thing is... he feels the same for me. And I know it's dumb and all, but... Fuck, I don't know what to do."

The expression on Inias's face was unreadable. "You're in love with an alpha?" he repeated slowly.

Cas swallowed dryly and nodded. "And there is more... um, fuck." He was so nervous to ask this of Inias. He was hoping his scent had changed. He needed it to be changed. Otherwise there was nothing he could do to get Dean. "Would you... um, please, check if my scent has changed?"

"Shit, Cas. Do you think… you might be true mates?" Inias asked as his hands dropped to Cas's collar and started unbuttoning his shirt for him.

"That's my hope," he whispered. "If I'm not, we're fucked. I have to be sure. He was afraid that his scent had changed since he met me... it could be a coincidence, but... fuck. I really hope it's not." He tilted his head to give Inias access to this scent gland, blushing a little because he knew that his throat was full of hickeys.

He could feel the pad of Inias's thumb caress one of the bigger marks. "Shit, have you been letting him mark you?" And before Cas could answer, Inias's nose was pressed against his gland as he took a deep inhale.

He had goosebumps all over his skin, pressing his eyes shut in nervousness. "Yes, I asked him for it," he whispered, his voice shaking. It was killing him to wait; his hope was everything he had left. Cas's fingers found Inias's arm, holding on to him. "And?"

Inias gave him a pointed look. "You do smell different. Shit, Cas."

Cas's heart skipped a beat and he exhaled a breath he hadn't been aware of holding. "Really? Are you sure?"

Inias nodded. "And that's bad for him. Really bad."

"What?" Cas asked in confusion. "No, I spoke to a lawyer today. If I can prove that we're true mates, I'm allowed to buy him. Why would that be a bad thing?"

Inias sighed as he rifled a hand through his hair. "True mate alphas turn quick, suppressors no longer work, they become unbearable to smell… He might go into rut."

"Oh, shit, really?" Cas rubbed his hand over his lips. "He was fine yesterday. And I'll see him tonight. What do you think I should do?"

"You need to call him now, get him here now, if you're his mate, you can keep him calm," Inias said as he stood up. "Maybe hire that lawyer."

"Alright, I'll call the agency right now." Cas quickly pulled his cell phone from his pocket, his hand trembling as he searched his contacts for the agency. When he pressed the call button, he reached out to intertwine his fingers with Inias's.

A female operator answered the call after a moment and Cas held his phone out, so Inias could listen to the conversation. "Hello, it's Castiel Novak. I'm calling for Dean. We just found out that he and I are... we're true mates." 

There was a beat of silence and some audible typing before she said, "I'm sorry, Mr. Novak, Dean is indisposed at this time. We can send you a substitute with some scent blockers."

Was the woman not listening? He took it off speakerphone and drew the device to his ear. "What do you mean indisposed? I don't want any other alpha. Like I just said, Dean is my true mate."

"Claiming to be true mates is not an emergency, if you do believe you are true mates, we can send you the necessary paperwork that will need to be filled out, and will arrange for a medical examination, and those doctors are booking out so you should start right away. And unfortunately, your current alpha is indisposed and will not be sent. You can take or leave the substitute."

Cas tried to stay calm, but it was difficult. "Why is he indisposed? Can you tell me what is happening to him?"

"No, I cannot." There was some more typing. "Would you like the substitute or not? I have calls holding."

"No, I don't want a fucking substitute!" Cas growled before he added, "And yes I want that paperwork, now. My lawyer will be in touch." He ended the call and threw his phone down on the couch. "Fuck!"

Inias drew him in for a hug. "What's going on?"

Cas pressed closer to Inias, trying to calm down his breathing. "They won't tell me what's wrong with Dean. They say I can't see him and they want to send me some paperwork. Fuck... this sounds like something that could drag out and... ugh, I need to call my lawyer."

Inias patted his knee. "You call the lawyer, I'm going to get changed. Go grab your wallet and keys."

Cas tilted his head. "Why? Where are we going?"

"To get your alpha," Inias said with a broad grin.

"How?" Cas asked as he picked up the phone from the couch and got up.

Inias shrugged. "Haven't thought that far ahead yet."

Cas rolled his eyes. "They wouldn't even let me know what's happening with him. I don't think they will let me see him when we’re in front of their doorstep." He sighed. "Maybe if the lawyer goes with us? I'll ask." He nodded at him before he walked to the door. "Come over to my place when you're done, alright?"

"You got it," Inias yelled from his bedroom.

When Cas was back in his room he immediately called the lawyer again, hoping that he could help. He seemed to be very sympathetic to his problem and extremely knowledgeable. When the young man answered his phone after the second ring, Cas exhaled in relief. “Mr. Winchester? It’s Professor Novak again. We talked earlier. It seems like I will need your help earlier than I anticipated. I just found out that indeed my scent has changed and I just called the agency and…” He inhaled, trying to stay calm, although his worry about Dean was increasing by the second. “They said Dean is indisposed and they won’t send him to me. They won’t even tell me what’s wrong with him. My best friend just told me that he could be in danger of going into rut because of me. Is that… Is there anything we can do?”

He could hear some rustling before he said, "If you're true mates they can't refuse you. What's the name of the agency again?"

"Medical Alpha Service, Inc. They weren't very supportive on the phone. They said something about paperwork they would send me and that they would arrange a medical examination. It sounded like a complicated and long process, and I fear that Dean needs help now. What if he really is in rut?"

There was a beat of silence before his lawyer said, "Do you genuinely think he might be in a rut? If so, we can use that as cause to expedite the process. If he gets stuck in his rut… it can cause a lot of damage."

That didn't sound good. His worry about Dean increased ten-fold in that moment. "They wouldn't tell me. If we drive over there… is there anything we can do, so they will let me see him?"

"Yeah, I'll meet you there, try to wait for me if you can."

"Of course, thank you so much. See you then." Cas ended the call and grabbed his jacket, wallet, and keys before he paced up and down in his room. He really hoped Mr. Winchester could make a difference, that they would let Cas see Dean.

When Inias finally knocked on his door, he basically dragged him towards the elevator. "The lawyer will meet us there. Did you know Dean could be in danger because of the rut?" He asked Nias, still feeling in shock about that information. Biology wasn't his forte, but it was a subject Inias taught in school.

Inias sighed and nodded. "Unlike Omegas, alphas can't regulate their times of the month with a substitute. And imagine if at the height of your heat, you weren't allowed to do anything? And that feeling was permanent?"

Cas gave Inias a pained look as they got into his car and he started to drive. "I would go crazy," he murmured before shaking his head. "But why did his blockers stop working?"

"His scent changed, Cas," Inias said with a soft sigh. "It changes his biology. The only thing that can help him now is his mate."

The whimper falling from his lips was involuntary. He looked out of the window, longing to see Dean again. "It's so inhumane that they won’t let him see me," Cas growled, although his logical brain knew why that was. 

There was nothing more dangerous than an alpha in rut. But Cas wasn't afraid. He knew Dean would never hurt him.

Inias nodded. "Yeah, I agree, but if you… aren't his true mate, it's insanely dangerous. I'm kind of glad they didn't just let him go if he is in rut."

Cas gave Inias a long look. "You know my scent like the back of your hand. If you say it changed, then I have nothing to worry about."

Inias grasped Cas's hand. "I still need you to be careful, okay?"

Cas intertwined their fingers and squeezed his hand. "I trust Dean with my life. I know he wouldn't hurt me." He gave Inias a soft smile. "I know I sound like a love sick puppy, but trust me, I'll be okay."

"You better be," Inias growled, but gave him a sweet smile. "And this lawyer guy is on the up and up? Not an ambulance chaser?"

Cas shook his head. "I searched on the internet for the best lawyer with an alpha rights background. He isn't just a lawyer, but he is also a political activist. There was a lot of praise in the press for him."

Inias hummed, sounding impressed. "What's his name?"

"Sam Winchester. Have you heard of him?" Cas asked, as he checked his watch. Ten more minutes.

Inias shrugged. "Sounds familiar. What's his deal? Did you ask? Why he's an alpha rights activist?"

Cas bit down in his lower lip. "No, I didn't. On our first phone call, I only asked about my options with Dean. But when we meet him you can ask. He said we should wait for him before going in."

Without missing a beat, Inias squeezed Cas’s hand. “He’ll be okay, Cas.”

"I'm so worried about him," Cas admitted. "I hope my lawyer can get them to let me see him. He sounded confident, so I'm trying to be hopeful." 

Cas was incredibly thankful for Inias being at his side for this. The distraction and his strength was exactly what he needed right now, when Nias parked the car right in front of the agency. 

"I think that's him," Cas murmured as he spotted a tall man standing next to the parking space, holding a suitcase.

“Shit, he’s tall,” Inias said as they approached him.

“Mr. Novak,” he said as he reached for Cas’s hand. “I’m glad you got here so fast.”

Cas held out his free hand to shake it. "Thank you so much for your quick response and coming here. This is my best friend Inias Knight."

“Sam Winchester,” he said as he offered his hand to Inias. Sam straightened his stance and opened the briefcase. “Good idea to bring your friend. He can verify your scent has changed.” He pulled a couple of papers out and nodded to the door. “To expedite this, you may have to put down a deposit for him.” 

"I already expected this." Cas nodded as they followed the lawyer through the big glass doors. "Do you think I will be able to see him?"

“We’ll fight until you do,” Sam said, tone assured as he approached the front desk. “Good evening, my client, Mr. Novak needs to file an expedited purchase claim for one of your alphas. Now.” 

The woman at the front desk raised her eyebrow. "Excuse me? That's not possible. This has to go through our medical examiner and our alpha resources management. And of course our lawyers."

Sam placed the papers he was holding down. “Unless there is evidence of a true mate, and your alpha’s scent has changed. He could very well go into a rut, and for the safety of your staff, it would be wise to release him to his mate’s custody.”

The woman squinted her eyes at him. "I'm calling my supervisor," she growled before she pressed a number on her phone. "Yeah, hi, Naomi? There is a lawyer in the foyer who wants us to give away one of our assets."

Cas hated how she was talking about Dean as if he wasn't a human being, one who was very likely suffering right in this moment.

She gave them a fake smile and nodded to the benches. "She will be here in a moment."

“Great, and if you could compile all of his health and behavioral records, that would be great,” Sam said, his tone serious and confident.

"You haven't even told me the alpha's name," she bitched back.

Cas rolled his eyes. "It's Dean."

As the secretary huffed, storming off into a back office, Sam grabbed the papers and moved to lean against the counter. “I’m glad you called me.”

Inias scoffed. “Yeah, she’s a real fucking peach.”

"I'm very happy you're here. Both of you. I don't know what I would have done without your help." He nodded at Sam with a grateful smile when he remembered Inias's question from earlier. "What made you choose alpha rights?"

Sam appeared taken aback, as though that wasn’t something he was asked often. “My, uh… my brother is an alpha.”

"Oh." Cas nodded with a sigh. "I'm sorry. That couldn't have been easy."

“Yeah, it uh… I was seven when suddenly my big brother wasn’t living with us anymore. I didn’t find out for years what happened to him, and by then…” Sam cleared his throat and shook his head. “He got lost in the system.”

Cas sighed and nodded. "And it doesn't help that their family name gets purged. I read about that." Cas leaned against Inias, his thoughts drifting back to Dean. He wondered if Dean still remembered his family name. It was driving him nuts that he was so close by and he couldn't just go to him.

Sam sighed. “We’re trying to change that.”

Inias let out a soft scoff. “I feel kind of bad I didn’t realize just how fucked this system is.”

"Yeah, same," Cas murmured. "We both grew up so sheltered from everything. No one in either of our families is an alpha."

“My brother was a first. In a long time. And he presented pretty young.” Sam shook his head, letting out a mirthless laugh. “My parents had no idea what to do.”

"What was his name?" Cas finally asked.

At that, Sam let out a soft, amused laugh. “Dean, actually.”

Cas huffed out a laugh. "Well, that's a coincidence."

He sat up straight when the elevator door opened and a middle aged woman with straight blond hair pulled back in an aggressively tight bun walked towards them. She didn't acknowledge Inias and Cas, but went straight to Sam. "Mr Winchester. What can I do for you?"

“You can get your staff to make the arrangements for an alpha transfer. My client is true mates with one of your alphas, and thus he has first rights.”

She gave him a cold smile. "I'm guessing you have proof for that claim? You know we can't just transfer a dangerous alpha to one of our citizens. If the Omega in question gets hurt, we're the ones stuck with the bill."

Sam pointed to Inias. “He brought someone who can verify his scent changed. And my guess, if he’s dangerous, that means he’s in rut. Which means his scent changed too.” Sam turned to Cas. “Would you feel comfortable meeting with Dean? There will be guards present.”

"Yes, absolutely," Cas quickly agreed.

Naomi squinted her eyes at Sam. "We haven't verified the reason for Dean's rut, yet. You only want your client to meet him to get a better standing in court." She looked at Cas finally. "Professor Novak. There is a high risk his rut could be caused by a medication error. If you're wrong, you could be in great danger. We can't be responsible for any harm that comes to you just because your lawyer wants to risk it."

"There is no risk," Cas replied confidently. "Dean is my mate. The only risk is that you are hurting this alpha in your care by denying him access to me."

Sam folded his arms over his chest. “If Dean doesn’t obey his mate, we’ll pull Mr. Novak right out. I want no harm coming to my client, any more than you want to deal with the insurance costs and fines.”

Naomi sighed. "Alright. Your friend has to stay here though."

Cas nodded and quickly turned to Inias, hugging him. "Don't worry about me," he whispered, his heart pounding in nervous excitement.

The woman pulled out her keycard and buzzed Cas and Sam in through an employee entrance. The halls were narrow, and when they reached the elevator, her bright red acrylic pushed the button for the basement.

“How long ago did he go into rut?” Sam asked.

"Last night," She explained. "He attacked our personnel and is very aggressive. We put him into the kennel for now to protect everyone in the compound. The doctor was going to look at him on Monday."

"Monday? That's in three days!" Cas was in shock that they would just keet Dean suffering like that.

“That is actually quite fast when it comes to alpha healthcare,” Sam spat, in a low enough whisper Naomi likely didn’t hear as she met with three guards, all holding tasers and cattle prods.

Cas thought he was going to be sick. The guards obviously weren't happy about the plan when Cas walked down the hallway to the glass front his mate was imprisoned behind. When he spotted him lying on the floor in obvious pain, he gasped. "Let me in."

The guards looked to Naomi for confirmation, before one of them held up the prod and smacked it against the glass, causing Dean to recoil. He looked up and snarled, before his nostrils flared. 

His eyes locked on Cas and he ran to the glass. He scratched at it, whining and whimpering. 

The guard smacked the glass again.

"Stop it!" Cas cried out as he walked to the door. "Please, let me in. You can see that he needs me."

Sam sighed and snatched the key from the guard’s hand, and opened the door slightly, waiting for Cas to take the lead.

Cas quickly slipped in before anyone could protest, closing the door behind him. "Dean," he murmured as he opened his arms for his alpha. "Come here to me. I've got you. I'm taking you home with me."

Dean sniffed the air, eyes narrowed in suspicion as he slowly drew closer. His breathing was ragged, and his pupils were dilated. He looked almost feral. When he inhaled again, he stormed forward, crowding Cas against the wall.

“Shit,” Sam said, “Get him out!”

Cas wrapped his arms around him to pull him tight, whispering, "Calm down, Dean. It's me. Cas. Your mate." He knew he should be afraid, but he wasn't. He presented his throat to Dean. "And you're a good alpha, my good alpha."

Dean aggressively started sniffing Cas’s scent gland before he started licking it. 

Cas looked over Dean's shoulder to Sam and shook his head. "Everything is okay, I got this." He turned his head a bit to press a soft kiss to Dean's temple, sliding his fingers through his hair. "My mate, Dean," he whispered soothingly. "Come back to me."

His breathing was ragged, chest heaving with each inhale as he looked at Cas. Dean’s hand came to rest at Cas’s pulse point. “Cas…” he growled out.

Cas exhaled in relief, smiling brightly at Dean. "Yes, remember. I promised you I would take care of you. Because I'm your mate. Yours."

Dean growled appreciatively and nuzzled his neck, scenting him. “Mate,” he growled, and Cas could feel his enormous knot pressing insistently against his hip.

If they didn't have an audience he would have totally done something about it. "Dean, I can take you home with me when you show you can control yourself. So be a good alpha and listen to your mate. When we're home you can mate me."

Dean drew back, breathing still ragged, but he shifted to move, getting down on one knee and bowing his head. Submitting to Cas.

Cas carded his fingers lovingly through his hair. "Just like that. You're such a good alpha. Good mate," he murmured proudly. When he looked up he met Sam's eyes with a nod. "I think we proved it," Cas said a bit louder. "Can I take him home now? He’s suffered way too long already."

Naomi looked annoyed and tutted, before she said, "You have paperwork to sign and we will need to arrange a down payment."

Cas nodded before he looked back at Dean, leaning down as he pressed a kiss to his forehead. "I love you, baby," he murmured.

Naomi cleared her throat. "We will order a special transport from here to your apartment, that you will have to pay as well. We can't risk him running into another alpha in this situation and getting territorial over you."

Cas still had his hand in Dean's hair, rolling his eyes. "Get everything ready. I won't leave his side until then."

Sam waved to Cas as he and Naomi left, one of the guards leaving with them as the other two waited at the door.

Dean scented Cas’s wrist and looked up at him. “Love?”

Cas knelt down to him, wrapping one arm around his shoulder, the other one cupped Dean's cheek. "Mmh? Are you alright?"

Dean leaned into Cas’s hand. “Love.”

Cas couldn't help the soft smile. He could feel Dean was a lot calmer now. Of course the rut was still affecting him, but nothing like before. He couldn't wait to have him for himself, giving in to his mate’s more animalistic instincts and letting Dean breed him. Hopefully by then Cas would be able to talk to him enough to make him understand that Dean could stay with him and never had to go back to this horrible place. "Yes, love," he purred, leaning his forehead against Dean's. "Very much."

Dean’s laugh was half growl, his lips curling up in a smile. “Cas.”

Cas pulled Dean's face against his throat, hoping his scent would help him to stay grounded. He closed his eyes with a smile, the thought sinking in that he finally could have Dean.

A knock on the glass panel made him look up. It was Sam, waving the documents. Cas grabbed Dean's hand and squeezed it. "Don't let go of my hand, love. Can you do that for me?"

Dean nodded as he squeezed Cas’s hand back.

Cas pulled Dean up with him, kissing his cheek as he murmured, "Good alpha." He knew from their time spent together that Dean had a praising kink, so he loved to praise him as often as possible.

He walked up to the door, where the guard carefully opened it. Cas really hoped they wouldn't lose their cool as they stepped towards Naomi and Sam. When he reached for his wallet he noticed Dean tensing up next to him. He frowned. "What is it, baby?"

Dean furrowed his brow as his eyes locked onto Sam. He sniffed the air and started drawing closer to Sam.

Sam was a Beta and he shouldn't register with Dean as competition, but still… Cas felt worried enough to hold Dean back. "Dean, stay with me. Be a good alpha."

Dean stood in place where Cas held him back, but he was leaning over, sniffing at Sam. He growled and looked at Cas with a whine. 

"Baby, this is Sam. He helped us so I can take you home," he explained, trying to calm Dean down. He exchanged a worried look with Sam.

“Sa–mmy,” Dean growled as his sniffing grew more frantic.

Cas's eyes widened. That sounded way too familiar. "Dean," he breathed out before his eyes locked with Sam's. "Mr Winchester, is this…"

Sam’s eyes widened and he took a step forward, drawing closer to Dean. Dean was practically vibrating with apparent excitement as the Beta stepped closer again. Sam looked Dean over, holding his hand out. “Dean?”

Dean was panting now, nodding frantically, but still being a good alpha and staying at Cas’s side.

"Oh, wow," Cas breathed out as he guided Dean closer so his mate was able to sniff at Sam's hand. "Is this really your brother?"

Dean grew really excited after scenting Sam’s wrist. He nodded at Cas. “Sammy.”

There was a tear that escaped Sam’s eye, and he rubbed it away. “Fuck… I think so.”

"Do you want to… should I let him go over to you?" Cas asked softly.

Sam nodded, dropping his briefcase and coat to the floor.

Cas looked at the guard and Naomi. "It's all fine," he said to them before he looked at Dean. "You can go to him, but stay calm, love. Be good." He hesitantly let go of Dean's hand before he stepped back and watched the family reunion unfold. He wished Dean's rut wasn't in the way of this, but he was looking forward to when they could see each other after this.

Dean rushed Sam, sniffing his neck before he wrapped his arms around Sam, spinning him around in a circle.

Sam laughed and drew back, looking Dean over in amazement. “I tried to find you.”

That was met with a growl of appreciation before he said, “Sammy.”

Cas couldn't help but smile. Dean's happiness was infectious. He grabbed his wallet, letting them enjoy their reunion in peace as he turned to Naomi. "Let me quickly pay for everything and sign, so we get out of your hair."

The transaction was quick and painless, and by the time they reached the lobby, there was an armored vehicle waiting for them outside.

Cas turned around to see Dean was walking calmly beside Sam, looking very happy. He waited for them to catch up before he grabbed Dean’s hand again. “I’m accompanying Dean in that vehicle. Mr. Winchester… would you come over when his rut is over? I’ll call you. I’m sure you two have a lot to talk about.”

Sam flashed him a bright smile. “Yeah, including writing up the contracts to make this a pro-bono case.” Sam shook Cas’s hand and patted Dean’s shoulder. “I’m glad he found you.”

Cas smiled brightly at Sam. “I can’t thank you enough for helping me get him out.” He rubbed the back of his neck. “Would you please find Inias and tell him everything is fine? I didn’t see him in the lobby. I’ll text him as soon as I’m able and please tell him not to worry.”  

Sam nodded and disappeared back inside the agency.

Dean nuzzled Cas’s neck, pressing a playful bite to his neck. “Mate,” he growled quietly.

It made Cas shiver with excitement. “Yeah,” he breathed out. “Let’s get you home.”

…. :::: :::: ….

The moment Cas had locked the front door behind them, he drew Dean into a deep kiss,  feeling relieved and excited to finally have him again. He pulled him backwards to his bedroom, toeing off his shoes as he grabbed the hem of Dean's shirt. "Lift your arms," he commanded softly. 

Dean did as he said, obediently allowing Cas to strip him. His breathing grew heavy and he leaned in to scent Cas’s neck with a possessive growl.

"Yeah…" Cas chuckled as he pushed Dean on the bed, helping him out of the rest of his clothes before he quickly stripped his own. "My alpha," he purred teasingly before he crawled onto bed with him, kissing him again. "Do you want to breed me?" he whispered against Dean's lips. The thought of Dean having his way with him already made him so wet, so much so slick was running down his leg. It was always so easy for him to get wet since he met Dean.

The growl that escaped was animalistic. Dean quickly flipped their positions, and as Cas landed on his back, Dean dove in, lapping at his slick before that talented tongue probed Cas’s hole.

"Oh, fuck, yes," Cas groaned and spread his legs wide. He had never seen Dean so take charge before and it was a hell of a turn on. Which was weird because with everyone else Cas prefered to be more dominant. It was probably because he trusted Dean. With his life, his heart, and with his body.

Dean growled again, and the reverberations sent a shock of pleasure through his nerves. As that tongue worked him open, a digit slipped inside. When two digits were in, Dean drew back and deeply scented Cas’s groin, fucking his fingers into Cas’s hole before he sucked Cas’s cock into his mouth.

Cas was losing it under the onslaught of pleasure. Even though Dean was in rut he still managed to take care of him, preparing him like a mindful lover. He buried his fingers in Dean's hair, moaning, "You're so good to me, Dean. I love you so much. Can't wait to feel you." He tried to brace himself on his elbows to look at Dean. "Do you want to mount me? Or like this?"

Dean drew back, and expertly flipped Cas onto all fours, still managing to scissor him open in the process. He gently bit the globe of Cas’s ass as a third digit made its way in.

Cas moaned into his pillow, his fingers clawing at the fabric. "Dean, yes. Fuck. Please. I need you," he breathed out, his whole body trembling in lust. Feeling Dean's teeth at his skin, was a massive turn on and he spread his legs a little wider, showing Dean that he was ready for him.

When the fingers disappeared, the warmth of Dean draped over his back as he mounted Cas, effortlessly slipping inside Cas’s hole, heated breath exhaling at the back of Cas’s neck.

Cas leaned back into his heat. "Dean," he groaned in lust. Dean's cock was so huge and he loved the way he stretched his hole so thoroughly. Having Dean's lips so close to his neck was driving him insane with lust, his hips moving backwards on their own. 

“Mate,” Dean growled as his hips started rocking into him. Thrusting with abandon, pistoning in and out, his teeth grazed along Cas’s scent gland.

"Yes," Cas cried out in lust as he tilted his head to give Dean better access. "Yes, mate me. Breed me, I'm yours." He wasn't thinking anymore, his lust had completely overtaken him. It almost felt like he was in heat.

Dean was grunting and panting as he fucked into Cas, he started sucking a mark into Cas’s pulse point. As he fucked harder and faster, he could feel the way his hole took that massive knot a little deeper with each thrust.

Dean had never taken him so hard before and Cas loved every second of it, especially how his knot pressed deeper every time. "Please, alpha. Need your knot. Slam it in," he begged. "Make me yours."

Dean growled again, teeth sinking into Cas’s shoulder as he fucked into him harder, that magnificent knot somehow pushing inside.

"Fuck!" Cas cried out as the mixture of pain and lust pushed him right into his orgasm. His channel tightened around Dean's big knot as he leaned back against him, enjoying the feel of Dean's teeth holding him in place. Thinking how close to his throat Dean had bitten him nearly made Cas come again.

Dean’s breath was heated and ragged as he exhaled against Cas’s skin, filling Cas with pulse after pulse. He drew back and licked along where his teeth had been, soothing, Dean was taking care of him.

Cas groaned in pleasure, looking over his shoulder at Dean. "I love you so much." His arms were trembling and it was difficult to keep himself upright. "Lay on the side?"

Dean was so gentle, shifting to their sides as he nuzzled against Cas’s neck. “Love you,” he growled softly, quietly.

Cas hummed and leaned against him. "How are you feeling, Dean?" Cas asked after a moment, hoping Dean's brain capacity was slowly coming back after the orgasm.

That was met with a contented hum. “Better. My mate.”

Cas smiled and tilted his head so he could kiss his cheek. "You sound tired, baby. Do you want to sleep for a bit before you breed me again?"

“Missed you. Want to… hold.” Dean took in a deep inhale before pressing a kiss to his neck.

Cas gasped softly. Fuck, he was still so sensitive there. He grabbed Dean's arm that was lying over Cas's hips and pulled his hand up to his chest, intertwining their fingers. "I missed you, too. I was so worried about you." He closed his eyes and smiled. "But you know what? Now we'll never have to miss each other again."

Dean hummed, pressing kiss after kiss to his skin. “Thank you.”

“You don’t need to thank me,” Cas replied softly. “You make me happy, Dean. And I love you. I will always take care of you. You’re my mate.” He chuckled softly before he looked at the red bite mark on his shoulder. “Is that our mating bite now?”

Dean chuckled and pressed a kiss to the mark. “Mine.”

"Yes, yours." Cas grinned, his heart full of levity and happiness. "And you are mine."

…. :::: :::: ….

Dean cursed as the spatula fell to the floor, spraying some of the eggs up into his face. He growled and wiped the partially cooked egg from his cheek. He pulled out a drawer to try and find a clean spatula, and ended up hitting his head on the open cupboard door.

“Fuck,” he growled as he shut the door and rubbed the back of his neck. He had wanted to surprise Cas with breakfast. He only remembered how to make scrambled eggs and toast, but… apparently he could barely do that.

When the toast popped up, some smoke billowed out, and the bread was charred. Dean pulled the toast out and growled, “Fuck!” He didn’t expect the bread to be hot enough to burn his skin.

He just wanted to make his mate breakfast. 

"Baby, are you okay?" Cas's voice was husky, a mixture of being amused and worried in his tone. He was leaning in the doorway, only wearing boxer shorts. His hair was a sexy mess and a reminder of their nightly activities.

Dean couldn’t help but pout. “It… it was supposed to be a surprise.”

Cas smiled at him as he walked up to him, pulling him into a tight hug. "I'm surprised." He laughed softly before he leaned back to press a soft kiss to Dean’s lips. "You sound a lot better this morning. Is your rut over?"

Dean nodded, gently cupping Cas's cheek. "Thanks to you."

Cas turned his head and kissed the inside of Dean's palm. "How much do you remember?"

"It's fuzzy, but I remember feeling really sad, and scared, and then I could smell you and it made those bad feelings go away." Dean furrowed his brow. "Does that make sense?"

Cas smiled brightly at him before he nodded. His mate looked excited. "Um, do you remember anything else?"

Dean tried to think, he remembered getting really excited, but… shortly after he bred his mate, so that could explain the feeling. Dean shook his head. "Just how I felt. It was good, all good feelings."

Cas's smile turned even wider. "Oh, man, I have a surprise for you. Maybe you should sit down." He guided Dean to the barstools. "I had help getting you out of that place. There is a lawyer who helped us, so you can stay permanently in my care. You will never have to go back to the agency."

Dean couldn't believe it. He almost had to wonder if maybe he had died from his rut, and now he was in heaven, looking at the angel that saved him. Dean cupped Cas's cheeks in his palms. "I… I don't know how to thank you."

"Seriously, there is no need. I would have gone crazy being apart from you for any longer." Cas leaned into Dean's head. "There is more though. The lawyer who helped me." Cas inhaled deeply, smiling wider. "His name is Sam Winchester."

Dean's eyes widened. Flashes of recollection over a certain scent… "Did… did you find my brother?" His heart was hammering in that pleasant, excited way.

"Yes," Cas replied softly. "Your family name was Winchester, right? I promised to call Sam when you're out of the rut. He will visit us and you two can spend some time together. I also have to text Inias soon before he breaks down my door out of worry for me."

Dean drew Cas in for a kiss. "I love you so much."

Cas wrapped his arms around Dean to pull him close to his body before he licked into his mouth with a soft moan. When he leaned back his mate was breathing a little heavier, a soft flush on his cheeks. "I should make us some breakfast," he murmured huskily.

"I think it can wait," Dean said as he lifted Cas in his arms and pushed him up on the counter.

"Fuck…" Cas bit down on his lower lip, giving him a heated look. "I don't know why, but just kissing you makes me weak in my knees."

"I'll carry you wherever you need," Dean murmured as he started trailing kisses down Cas's neck.

Cas groaned and presented his throat to Dean with a soft whine. "Where do you want to take me?"

Dean growled, "Everywhere." He hiked Cas's hips up to pull his boxers down to his knees. Dean slipped a finger between Cas's legs to tease his hole.

Cas braced his palms behind him on the counter, leaning back with a soft groan as he spread his legs for Dean. His hole was still wet with Dean's come from a few hours ago, fresh slick joining as he teased him. "Dean," he whined. 

Dean drew him in for a kiss as he lined them up, his cock easily slipping into Cas's come wet hole. Fuck… it always felt as good as the first time. "My mate," he growled.

"Yes," Cas groaned, crossing his legs behind Dean's back. "You feel so good in me."

The pleasure was perfect, and being in his love's arms, his true mate's… made everything all the more powerful. He started thrusting inside Cas. "Love… you."

Cas hummed, his eyes never leaving Dean's. "Love you. Uh, fuck, Dean. I love how much you filled me... and now adding more... fuck."

Dean couldn't help but growl. He loved his mate's filthy mouth. He fucked into Cas harder, scenting his neck for a new gush of slick. He wanted to knot him then and there.

Cas moaned loudly and Dean loved how much his mate was enjoying himself. The heated look he was giving him was probably the sexiest thing Dean had ever seen. "Knot me, alpha, please. Need you to breed me." He could feel his channel tightening around Dean's cock, knowing that his mate was close.

Dean spread Cas's cheeks and worked his mate's hole down around his knot.

"Just push it in, baby," Cas groaned needily. "I can take it. Please."

Dean groaned as he pushed inside, his vision whiting out from the sheer pleasure. "Cas," he growled as he filled his mate again.

Cas cried out Dean's name, holding on to his biceps as he came all over his own stomach. Breathing hard with parted lips he trailed his fingertips over his skin, his beautiful blue eyes never leaving Dean's. "I love you so much."

Dean nodded and drew him in for a kiss. "I love you," he echoed as he carded his hand through his beautiful mate's hair. 

Cas started to laugh against his lips, softly shaking his head. “I thought I would make you breakfast, instead I was your breakfast. Not a bad way to start the day.”

Dean chuckled and nuzzled into the crook of Cas's neck. "Well, you are the sweetest thing I've ever tasted."

Like he expected, his Omega gasped in delight. “Dean,” he whined, “You know I’m sensitive there.”

"I like when you squirm," he murmured fondly.

"Oh, do you now?" Cas teased him back, smiling happily at him. He nudged his nose against Dean's before he said, "Would you carry me to our bed? It's more comfortable there to wait until your big knot goes down."

Dean nodded and carefully scooped Cas in his arms. It was awkward, considering he was still filling his mate with seed, but he would do anything Cas asked. When they reached the bedroom, he carefully laid Cas down and draped himself on top. "I'm sorry I burned breakfast."

“It’s the thought that counts and hey, you have time for the rest of our lives together to learn how to not burn toast,” Cas replied as he pressed a kiss to his nose with a hum. “Fuck, I need a shower before I do anything. You’re seriously filling me good, baby.”

“I love filling you,” he purred into Cas’s ear.

"Oh, yeah? Why is that?" Cas licked over Dean's neck before he sucked the skin between his teeth, marking him.

Dean hummed, filling Cas with more come. “Because I love you.”

Cas leaned back, giving him an amused look. "Oh, I see. Then you must love me a lot, because I'm pretty sure I'm overflowing right now."

Dean couldn’t help the appreciative growl. “Do you want my knot to go down?”

"Is talking about filling me up good to breed me, making you horny?" Cas whispered teasingly into his ear.

Dean couldn’t help the deep growl. His mate knew exactly how to turn him on. Dean suspected Cas liked it when Dean got aggressive.

Cas hummed when Dean pumped some more seed into him. His mate let his head fall back against the pillow, rocking his hips softly up against Dean. "This feels so perfect, Dean. You in me. Have I ever told you how afraid I was to take a real alpha knot? Now, the notion seems ridiculous to me."

Dean let out a soft, slightly jealous growl. “I’m glad I’m your first.”

Cas raised his eyebrows in obvious surprise. "You just sounded jealous over a sex toy. Which was the only knot I ever tried."

“I’ll destroy it,” he growled, pressing a possessive kiss to Cas’s lips.

Cas deepened the kiss, before he leaned back a little. "I hated that thing. Never got it in because I couldn't get wet enough. I had this problem all my life. I thought my body was broken. But with you… it's so easy. I think I always waited for you."

Dean couldn’t believe how lucky he was. To have found his true mate in the perfect Omega. “Thank you for waiting for me.”

Cas gently stroked over Dean's cheek, giving him a lovely smile. "I'm so happy I got you out of that place." Cas wiggled a little bit before he sighed. "I have to confess that I can't wait for you and your brother to reunite."

Dean nudged his nose against Cas’s pulse point. “I never thought I’d see him again.”

"He was looking for you. But since alphas get their family name purged, it wasn't easy for him." He carded his fingers gently through Dean's hair. "He is a lawyer, specializing in alpha rights because of you."

Dean couldn’t stop the tear that escaped. He cuddled against his mate. “I always knew he was a smart kid.”

Cas tightened his arms around him before he reached up and wiped the tear away with his thumb. “I think your knot has gone down. Let’s take a shower together and start the day. What do you say?”

Dean nodded as he slowly pulled out. He growled appreciatively at the sight of his seed dripping from his mate’s hole. He quickly lifted Cas in his arms and carried him to the bathroom. “I like the sound of that.”

Cas leaned his head against Dean’s shoulder with a contented purr. “I love that you carry me.” He grabbed his shoulder when they were standing in front of the shower and pressed a kiss to his lips, before Dean let him down. 

His mate turned to the shower, bending over to present his ass as he started the water. He looked enticingly over his shoulder. “You know, you made me very dirty and I think you should clean up this mess.” 

Dean parted Cas’s cheeks, using his thumb to push some of his seed back inside his mate’s tempting hole. “Hmm, I think you’re right.”

Cas braced himself against the edge of the wall with a deep groan. “Fuck,” he cursed under his breath before he stepped into the shower and pulled Dean under the warm water with him. “You make me crazy, Dean Winchester.”

“And you make me happy, Castiel Novak.”

Cas gave him a thoughtful look for a moment that Dean wasn’t sure what it was about before he leaned close and kissed him. “We should really call Sam soon. I have a few more questions for him,” he finally said, before he grabbed the shampoo and started to wash Dean’s hair.

“Could…” Dean ducked Cas’s gaze. “Could I borrow one of your shirts?” Nothing Dean had with him was nice, and… he wanted to make a better impression on his brother.

“Of course.” Cas kissed his shoulder. “We can also do some online shopping later, if you want more clothes. Do you have things left at the agency?”

“Not very much,” he said as he started soaping up Cas’s body. “All I really need is in front of me.”

Cas laughed softly and shook his head. “You’re very charming, Dean.” He flicked Dean’s nipple before he grabbed the shower gel and returned the favor, seemingly having fun spreading the soap everywhere on Dean’s body, especially the sensitive spots.

Dean hummed. “I’m not sure if you’re trying to make me clean, or dirtier.”

“Um,” Cas replied with a playful smile. “What can I say? You bring out the worst in me.”

“If this is your worst, then I am very lucky,” Dean purred as he drew Cas in for a kiss.

Cas deepened the kiss with a soft gasp, his hands sliding down to Dean’s hips, before one hand gently started washing Dean’s cock. “On one hand, I’m trying very hard not to rile you up, but on the other hand… it is so much fun.”

Dean let out a soft growl. “I think you like my animalistic side.”

He could hear the way his mate’s breathing hitched, a sound that he really had fallen in love with. “Yes, I’ll admit it really turns me on when you are like this. All growls and aggressive. You even bit my shoulder in your rut.”

Dean gently cupped his cheek. “It was my compromise to myself. I really wanted to give you a mating bite.”

He leaned into his palm, turning his head to press a kiss to his hand. “I want to ask Sam about that. If there is a possibility to make our relationship official in any way. Like a mating bite or… something else.”

“Do you think…” Dean licked his lips. “Because we’re true mates, we could?”

“I have no idea, but I hope so,” Cas replied softly. “The most important thing is that you can stay at my side.”

Dean flashed him a smile. "Every day for the rest of my life."

Chapter Text

Chapter 5

Dean was attempting to tie the tie Cas let him borrow. He really wanted to make a better impression on his brother. Considering their first reunion was in the middle of a damn rut. 

When he fucked up the knot for the fourth time, he sighed and pulled it through the collar and off, tossing it to the side with a frustrated growl. At least the shirt Cas gave him fit nicely. A simple light blue button up shirt.

He looked down as he unbuttoned the sleeve cuffs and started rolling them up.  

The sweet scent of his mate reached his nose before he could hear Cas leaning against the doorframe. "Need help, handsome?"

Dean chuckled as he turned to him. “I never learned how to tie a tie.”

Cas wandered past him to pick up the tie from where it had landed on the bed. A soft smile played around the corner off his lips as he stood in front of Dean, gently pulling the fabric around Dean's neck. He licked over his plush lips, concentrated frown on his face as he tied the knot, carefully pulling it up when he was done. His palms stroked sensually over Dean's chest and shoulders as his eyes locked with Dean's. "All done. You look very cute."

Dean cupped Cas’s cheek and drew him in for a tender kiss. As he drew back, he braced his forehead against Cas’s. “I just… I want to make a better impression.”

"You're nervous," Cas stated softly, carding his fingers through Dean's hair.

“Well, the first time he saw me… after decades… I was in a rut.” Dean ducked his gaze, a well of shame washing over him. “I just… don’t want him to think that’s all I am.”

Cas inhaled deeply and nodded. "Your brother is a very intelligent young man. He knows you're more than that and he has always looked for you. If he thought less of you, do you think he would have become such a successful lawyer for alpha rights?"

Dean couldn’t help but smile at that, while he knew those things, as an alpha, it was safest to just assume the worst. “Thank you, Cas.” He leaned in and pressed a gentle kiss to his cheek.

"Anytime." Cas winked at him. "I love you." He grabbed Dean's hand the moment the doorbell rang.

Dean gently squeezed Cas’s hand and slowly exhaled. “I love you too.”

"Relax, honey," Cas said in a soothing voice as he walked with him to the front door, opening it. 

Dean swallowed against the lump in his throat and held his head up as his brother was revealed. Damn, the kid got taller, easily taller than Dean, and his hair was down to his shoulders. While they didn’t look related, Dean knew that smell anywhere. It had been years, but the scent of his family stayed with Dean long after he was whisked away to that camp.

“Hiya, Sammy,” Dean breathed out.

"Dean," Sam said before he stepped forward. Dean suddenly was engulfed in strong arms , his brother hugging him tightly. "It's so good to finally see you again."

Dean let go of Cas to wrap his arms around his brother, a tightness in his chest strangling the breath out of him. He clung even tighter and just held on for a moment, willing away the tears burning at his lids. “Fuck… I can’t believe it’s you.”

"I searched everywhere for you," Sam pressed out after a moment before he finally leaned back and gave him a once over, his eyes watery, but he was smiling brightly. "You look good."

Dean shook his head in amazement. “I had no idea. I just… I assumed you forgot about me.”

"Never." Sam shook his head. "That you had to leave was hard on all of us. We really missed you, Dean. And you have no idea how glad I am... not just because I found you, but also because... I could help to get you away from where you've been."

“I… I don’t know how to thank you,” he said as he looked at Cas. “I never thought I would know what true happiness felt like.”

Cas gave him a soft smile as he gestured to Sam to come inside. "Come in, let's sit in the living room. Can I get you a coffee?"

Sam nodded brightly as he followed Cas, his eyes kept falling to Dean, smiling happily at him. Cas grabbed Dean's shoulder. "Do you want a Coke, baby?"

“Yes, please,” he said as he pressed a kiss to Cas’s cheek before he made his way to the couch, moving to sit.

Cas vanished into the kitchen, leaving them alone on the couch. Sam folded his hands over his own knees. "How are you? Everything okay with the transition? Did you get all your belongings?"

Dean nodded. “Not that I own very much.” He rubbed the back of his neck. “Tell me about you. Tell me everything I missed.”

Sam nodded softly and looked down at his lap, rubbing his hand over his chin. "After you were taken from us... things... didn't go so well back home. Dad, he didn't..." He sighed deeply, shaking his head. "He died a few years ago."

The pain in his heart was unexpected, considering how long it had been. "How did he die?"

Sam still didn't look at him and Dean could see that this was hard for his brother. "He was sick. Liver failure. He, um, drank too much. Mom and him seperated a while back." When Sam looked up he gave him a warm smile. "I've told her that I found you again... she was... she was beyond happy to hear that you're okay."

"She was?" Dean couldn't help but ask. It had been so many years, and they had so easily let Dean leave with Bobby, he just assumed that… they didn't love him.

Sam reached out to touch Dean's shoulder. "Dean, they were broken when you... we all missed you so much."

Dean couldn't help the sad smile. "I just assumed…" he shook his head. "Do you… do you think she'd want to see me?"

Sam smiled brightly. "There is nothing she wants more. Believe me. She just was... I don't know... She wanted to know how you feel about it first. If you would even want that."

"More than anything," Dean said, voice cracking slightly. He wiped at the tear that started to escape.

Sam nodded, smiling brightly. "She will be so happy. I'll call her when I'm home and give her Cas's number, alright?"

"Yeah, please. I… would love to hear her voice." Dean swallowed against the lump in his throat and smiled at Sammy. "So, a lawyer, huh? I always knew you were smart."

At this moment Cas came back into the kitchen, handing Sam his coffee and Dean his Coke, before leaning over to press a kiss to Dean's forehead. "I'm going over to Inias’s for a while, so you two have some quality time, alright?"

Dean smiled up at his mate. "I'll miss you," he said softly.

Cas gave him a soft smile and carded his fingers through his hair. "I'm only across the hallway should you need anything, and I'm sure you won't have any time to miss me." He winked at him before he turned to Sam. "Thank you for coming, Sam. I'm really happy you two got a chance to reconnect."

Sam stood up and shook Cas's hand. "Thank you. I'll call you later with a few more details about the case and things we have to finalize before the court appointment. I know you also said you had questions."

Cas exchanged a quick look with Dean. "Um, yeah. We can do that later. You two talking is more important right now."

Dean was so in love with his Omega. As Cas departed, Dean turned to Sam again. "So, tell me more about your life. Are you married?"

Sam smiled brightly at him. "Yes. I have a wife. Her name is Eileen. She is a Beta like me. We actually have our first kid on the way, so you will be an uncle."

Dean felt his heart swell. "Would… would I be able to meet her? And your baby?"

Sam sighed and rubbed the back of his neck. "There is still a lot that Cas and I have to work through before I can answer that for certain. At least when it comes to you visiting us. We, on the other hand, can visit Cas any time we want, which also means we would be able to visit you. So yes, you will meet her and our baby."

Dean couldn't stop the smile, but he had never thought about being able to go out. As an alpha he was always required to report where he was going and was timed. An alpha’s brief periods of time alone outside were highly regulated. "Do you think I'd be allowed to visit you guys?"

"I'm not sure, but I will try pushing for a traveler permit for you. Which would mean that when you're accompanied by Cas, you would be allowed to go wherever he goes. It really depends on the judge, but I think Cas has a very good chance because he has a high standing in society with his job at the university. A doctor from the court will conduct a genetic test on the two of you, proving that you're true mates. That means there is a guarantee that you can't get dangerous with him at your side. The chances are good, Dean." Sam leaned closer to him. "Do you have any questions?"

Dean shook his head. "Not now, I'm sure I will, but this is all so much more than I expected. I… feel like I'm dreaming."

Sam gave him a sad look. "I wish I could do more. I... I can't imagine how hard life must have been for you."

Dean flashed him a reassuring smile. "It hasn't been as bad as it could be. I'm a lucky one."

"Dean." Sam shook his head. "You were forced to be a sex worker."

Dean let out a soft laugh. "Well, considering the alternatives… And Benny always told me sex work is the oldest job. There's a dignity in that."

Sam raised an eyebrow and nodded. “Well, when you say it like that. I just… I just wanted for you to choose, you know?”

Dean flashed him a smile. "I would love to be able to do that, but it's kind of pointless to wish for something you can't have."

“I guess that is a very healthy take on life.” Sam replied with a soft smile. He shook his head. “I still can’t believe I found you again. When Cas called me the first time and told me his alpha was called Dean… I really tried not to hope.”

Dean barked out a laugh. "What a small world. So what made you want to get into alpha rights?"

Sam gave Dean a pointed look. "Take a wild guess," he replied with a chuckle. "It wasn't just hard on our parents when they took you."

Dean had never felt so touched. He braced his hand on Sam's shoulder. "Thank you for fighting for me."

Sam covered his hand with his own, squeezing it. "There is no need to thank me, Dean. You're my brother. I'll always be there for you."

The tear escaped then and he let out a slightly choked laugh. "Same. It's why I was considered a submissive alpha, because I wanted to always stay in control of my alpha side. To hopefully one day be returned to my family." After several years he realized that would never happen, but by then, he had mastered control over his instincts.

Sam gave him a proud look. "Yeah, Cas told me that you're special. But I never doubted that."

Dean flashed him a smile. "He said that?"

"Yeah, you didn't know?" Sam asked with a smile. "He is pretty gone for you."

Dean couldn't help but chuckle as he shook his head. "I can't believe how lucky I am."

Sam grimaced. “You really are, Dean. In my line of work I witnessed a lot of shit. Seriously, you won the lottery with Cas. I wouldn’t have helped him otherwise, you know. I know how he sees you. And that’s very different to how a lot of other Omegas see an alpha. You aren’t his property in his eyes, you’re an equal partner. No matter what the law says, this is how he looks at you.”

Dean looked at a picture on the end table, of Cas and his friend Inias, and couldn't help the soft sigh. "I think I would love him even if we weren't true mates."

Sam nodded with a soft laugh. "I think that is also true for him. The first time we talked, Cas didn't know that you were true mates. But he already knew that he loved you." His brother's gaze went to the picture, too. "Ah, that's his friend. You didn't see him, but he was with us when we got you from the agency."

Dean would have to thank Inias for being there for Cas. It must have been scary. "I still can't believe I never have to go back to that place."

His brother let out a soft sigh. "Yeah, I'm glad you don't. Having found your true mate... it changed you.  You were lucky."

Dean sighed. He was, and all of his friends, the alphas he had known for so many years, were stuck there. He held his brother's gaze. "Is there anything you can do for my friends?"

Sam shook his head. "I'm sorry. I'm working on a political angle to give alphas more rights. But... I can't do anything for them individually as long as there aren't also some sort of Omega rights involved." Sam looked up at him, his eyes sad. "I don't know how much you know about why you're here? The law says that an Omega has a right to be with his true mate. It's not the other way around. So, the fact that Cas wanted you is the reason we were able to get you out. He had to buy you out of that contract."

Dean let out a sigh and sank back against the couch. "We aren't… we aren't animals."

"I know you aren't," Sam murmured softly. "That's why me and a lot of other people are working for a better future for alphas. And Cas... Cas especially doesn't see you like that, you know that, right?" 

Dean nodded. "I do. I…" he looked at Sam. "I want to help." 

Sam gave his brother a thoughtful look. "You know what? Maybe you can."

The warmth Dean felt was wondrous, a buzzing of hope. A purpose, a way to help his kind. Maybe this was what Cas meant by doing something you love. 

…. :::: :::: ….

Cas was leaning back against Inias’s cozy couch, his eyes closed and a glass of white wine in his left hand, that he was balancing on his knee cap. “Fuck the last few weeks have been exhausting,” he breathed out. “I can’t thank you enough for being there for me. Through everything.”

Inias patted his knee. "What are pretend boyfriends for?" He visibly cringed. "Damn, I probably shouldn't joke like that anymore, huh?"

Cas chuckled and blinked up at him. "He knows that you aren't. I confessed to it pretty early on."

"You must really love him," Inias said, flashing Cas a soft, slightly amused smile.

"I do." Cas gave him a tired smile before rubbing his fingers over his way too heavy eyelids. "We just belong together, as corny as it sounds."

"You okay?" Inias asked, tone concerned as he gently grasped Cas's shoulder.

Cas sighed deeply before he shook his head and then nodded. “I don’t know. I just feel a little tired. It was all… a lot.” He leaned his head back and stared at the ceiling. “And there are so many things that I haven’t had the chance to think about, yet. You know me. I like to plan things. But now everything is happening and I feel like I can’t even stop for a moment to just stop and think.”

Inias wrapped his arm around Cas's shoulder and drew him in for a hug. "If it helps, I'm damn proud of you."

Cas grinned for a moment and hugged his friend back. "For what? For buying an alpha as if he is a piece of furniture?" He leaned back to look at Inias. "I sometimes just can't imagine how this life must have been for Dean, you know?"

Inias sighed. "It's a fucked up thought, but it's the world we live in, and at least… shit, at least he was lucky enough to find you."

“But…” Cas sighed. There were things, negative thoughts in his mind that were really hard to talk about. “What if,” he started quietly. “What if he only stays with me because of that? Because he has nowhere else to go. Because now I… own him and he has no other choice but to stay with me.”

Inias gave him a pointed look before he got up to stand. He picked up some paperwork off of the dining table and came back to Cas. "So, uh… while I was left alone in that lobby, I, uh… decided I wanted to know about Dean. So I made a copy of his files. Honestly, they should have better security…" Inias handed him the papers. "Read the transcript of what happened before he went into rut."

Cas wasn’t sure why he was surprised that Nias had done something like that, not that it was important right now. He opened the papers and read over the files before he found the page Inias had referred to. Dean had continuously asked and worried about him. Not once had he been worried about himself. It was hard to read and his heart hurt in his chest reading those lines, imagining the distress his mate must have felt. “Fuck,” he whispered. 

"Trust me, that alpha is gone for you."

Cas couldn’t help but smile at Inias. “I hope it stays that way and he doesn’t get annoyed with me… or bored.”

Inias chuckled. "He won't."

“You did. Who’s to say he doesn’t wise up?” Cas replied with a laugh, trying to mask his insecurity. 

Inias quirked his brow. "You and I don't want the same thing, Cas. I don't want a relationship, or romance. You do."

"Yeah, I know. I guess I just sometimes think it's too good to be true. He is so… perfect. Like he was made for me. Just being with him makes me calm. You have no idea what he has done for my sleep cycle since we met."

Inias smiled then. "And he loves you. So much so you're all he cared about while in a damn rut. I think you're worried over nothing."

"Alright, alright," Cas held up his hand before taking a sip from his glass. "Anyway you two should really formally meet soon. I'm not allowed to take him outside of my place at the moment. Sam is compiling a case file for court so I'll get permission to do that. Until then, you have to come over to my place for our movie nights."

Inias nodded. "Do you think he'd be allowed to leave?" Inias sounded skeptical.

"Not without his prison guard at his side," he replied sarcastically as he pointed at himself. "If at all. Sam said it depends on the judge."

"Fuck, I never realized how restricted alphas were." Inias shook his head. "Well, even if you don't succeed, you're both welcome here, restrictions be damned."

Cas took another sip from his glass, giving Nias a teasing grin. "I'm still convinced your parents should have called you Rebel."

Inias rolled his eyes. "What can I say? I hate rules."

"I know, that's what I love about you." He looked at his watch and sighed. "So, what are we doing with this beautiful evening?"

Inias pulled Cas close and said, "You're gonna cuddle with me and we're gonna watch garbage TV."

Well, that sounded perfect and like exactly what he needed. Not thinking. He sighed contentedly as he leaned his head against Nias's shoulder, watching how he flipped through the channels. "Tell me something, anything," he murmured.

"I'm getting a stupid award," he said nonchalantly.

Cas leaned back and gave Inias a surprised look. "For what? When? Is there a ceremony where I can come and take embarrassing pictures?"

Inias shook his head. "Nope, nope. Because I'm not going. Some… teacher of the year crap."

“Oh, no, you have to go!” Cas really tried not to laugh. “I bet you will even get like a framed document.” He playfully elbowed him in the side. “I could be in the audience and applaud really loud when they talk about you. And I could shout something like, ’that’s my best friend up there!’”

Inias playfully shoved Cas back. "I'm definitely not going now."

“Jokes aside, I think you earned it. And if you go, I’ll cook for you. A dinner of your choosing. What do you think?” he asked, realizing how much he had missed these talks with his best friend. Getting a bit of normalcy back after these turbulent last few weeks of worry.

Inias hummed and rested his head on Cas's shoulder. “You can just cook for me for no reason too."

“I could... but I really want to see framed proof that I have the most awesomest best friend.” Cas replied as he started to relax, closing his eyes for a  moment.

Inias ruffled his hair. "Do you want to take a nap?"

“No, if I take a nap now, I’ll be too tired to do anything after.” He sighed softly, hating how nice a nap sounded though. “I hate how comfortable you are.”

"You don't." Inias chuckled and cuddled him. "So… how does it feel knowing you found your true mate?"

"Like I'm finally complete," Cas said after a long moment. He rubbed his thumb over his own knee. "I wonder if… everyone has a true mate out there. But that because of our society and rules it's making them harder to find."

Inias shrugged. "I mean, it's possible, and if that's the case… shit, it seems almost cruel for us to all continue like this."

"It really is." Cas shifted so he could look at Nias. "It just feels so right to be with him. His scent alone calms me down and I constantly feel like I belong… that I'm safe and loved."

Inias smiled. "I'm happy for you, Cas."

"Well, thanks. I'm happy for me, too," Cas joked before he asked, "What about you? If you had a true mate wouldn't you like to find him?"

"I mean, no? I have no interest in any kind of relationship, so a soul bond sounds terrible."

Yeah, that made sense. Cas grinned at Inias. “Let’s be real, it’s not like any alpha could handle you.”

Inias quirked his brow. After a beat of silence he relented with a shrug and said, "Yeah, you're not wrong."

He knew he was being ridiculous, but his mood was rapidly improving now that his worries about Dean started to subside. “I can’t help picturing it. I mean, just the fact that you’re such an adamant top.” 

Inias nodded. "But I still get that need periodically. It's annoying." He chuckled. "Now I sound like you."

“No, I totally get it.” Cas gave him a long look. “It’s annoying when you want to submit to someone just because you’re in heat or your hormones when it’s usually the other way around.” Cas wondered all of the sudden if Dean would mind Cas topping for a change.

Inias nodded. "But look at you, you got a submissive alpha." 

“Yeah, that’s true but I haven’t asked him… we haven’t…” Cas rubbed the underside of his nose. “God, I haven’t topped yet and I feel ridiculous that I haven’t asked him. I mean, just because he is an alpha doesn’t mean he always has to top, right?” 

Inias shrugged. "Honestly, I don't know, but he's pretty gone for you, he'd probably do anything you ask."

“You know what? I will ask him when we’re alone again.” He looked at his watch with a sigh. “Or maybe tomorrow. I don’t know. He will probably be emotionally exhausted after talking with Sam. I mean, they haven’t seen each other for such a long time.”

"That's so crazy, that you hired your mate's brother." Inias chuckled and shook his head. "Like something straight from a rom-com."

Cas couldn’t help but agree. “I know, what are the chances, right?” He grinned then before shifting on the couch to put his head on Inias’s lap. “I’m very happy for him. Reuniting with his family. I’m glad I’m giving them some space though because I felt emotional just watching them.” He gave Inias a pointed look. “And please don’t make fun of me for that.”

Inias's expression was serious. "I would never. I think it's amazing what you've done, Cas."

Cas furrowed his brow. “I haven’t done anything.”

Inias let out a scoff. "You saved that alpha. In more than just one way. And you deeply care for him. This could have been transactional and instead, it's love. That's pretty damn amazing."

“Well, you and Sam helped a lot. So, thank you, for helping me through this time,” Cas replied, giving Inias a soft smile. “And I definitely will have your back when you go and accept your teacher of the year award.”

Inias rolled his eyes. "No."

…. :::: :::: ….

After spending a good minute hugging his brother goodbye, Dean closed the door and felt a wash of pure, unadulterated hope. Hope for a future. Something he had never felt before.

Dean couldn't stop himself, he rushed forward and pulled Cas flush. He cupped his face and held his gaze. "I can't even begin to express what I'm feeling right now. I love you so much, you have saved me in so many ways, and even if I am never allowed to leave your home ever again, I don't care. You have given me love I never thought I could have."

Cas gave him a soft smile. "I guess you had a very nice first meeting with your brother?" He grabbed Dean's wrist and pulled him to the bedroom before Cas pulled off his shirt and jeans.

Dean loosened his tie, resisting the urge to rip the borrowed shirt open. "I did. How was Inias?"

“He’s won a teacher of the year award and we need to force him to go to the ceremony.” Cas chuckled deeply. “Other than that, he is fine. It was nice spending time with him.” He pulled off his boxer shorts and crawled under the covers, watching Dean.

Dean stripped the rest of his clothes in seconds flat as he crawled onto the bed, his cock heavy as it stirred to life. "I'm glad you have him," he said as he crawled close and drew Cas in for a kiss.

Cas hummed into the kiss before he leaned back. “Dean, I have a question.”

"Yeah?" he asked as he flashed Cas a smile.

He could see the way his Omega was chewing on his lip, indicating that he was nervous. “Um, so I know… because you’re an alpha I have never asked, but… could you, um, imagine… that when we have sex. Um… that I would top?”

It took Dean a moment to realize what Cas was asking. "You… want to mount me?"

“Yeah,” Cas breathed out before he grabbed Dean’s neck and pulled him into a kiss. “I really want to fuck you.”

He had never experienced that before, but his cock twitched with interest at his mate's words. Dean nodded into the kiss and breathed out a soft, "Okay."

“Really?” Cas asked, sounding breathless as he leaned back to look at him with wide eyes. Almost as if he hadn’t anticipated the answer.

Dean smiled. "I've never done that before, but I love you. I want to experience everything with you."

“I just want to let you know… that you’re allowed to say no to me, okay?” Cas said and the expression on his face showed Dean that his mate was clearly worried about something.

Dean furrowed his brow and cupped Cas's cheek. "I appreciate that, but why would I say no to my mate? Making you happy makes me happy."

Cas looked down at the bed. “I… I just feel… It’s because I bought you. I was worried that you… I don’t want you to feel different towards me.”

"You didn't buy me, Cas. You saved me." Dean gently tilted Cas's chin up to look at him. "That's how I'll always see it."

Cas inhaled a deep breath before he nodded. “Alright. I… I know my worry has nothing to do with you. I just sometimes can’t believe my luck… that you want to be with me.”

"Why? You're the most devastatingly handsome, kind, wonderful Omega I have ever met."

Cas shook his head, a soft smile on his lips. "It's alright, Dean. I just needed to be sure." He licked over his own lips before he leaned in to draw Dean into a soft kiss. "How was your evening with Sam?"

Dean smiled. "Good, if it's okay with you, he'd like to bring his wife over sometime and, um… maybe my mom?"

“Of course it’s okay. More than okay. I’m really happy that you will see your family again.” Cas pulled him into a tight hug. “Are you nervous about seeing your mom again?”

Dean rifled a hand through his hair. "I am. I just… for my whole life I just assumed they didn't want me, and that's why they sent me away."

Cas nooded, stroking softly over Dean's back. "If tonight was emotionally taxing for you, we could just cuddle under the blanket and sleep. Sex isn't going anywhere."

Dean wrapped his arm around Cas. "I do like cuddling you."

Cas laughed before he gave Dean an enticing and playful look. "Do you now? Because this feels to me like you're trying to catch me."

Dean growled playfully as he pulled Cas on top of him and drew him in for a kiss.

The playful side of Dean was one of his favorites to see. Cas licked over Dean’s lips as he rocked his growing erection against Dean’s. So much for cuddling. Dean always managed to rile him up with ease.

Dean groaned in response, drawing back slightly to hold Cas's gaze. "Did you want to mount me now?"

“Yes,” Cas breathed out. The thought alone made his cock twitch. He slid off of Dean, giving him a heated look. “Present for me?”

Dean nodded, shifting onto all fours before he lowered his chest to the mattress while keeping his hips hiked in the air.

Fuck, this was so sexy. 

Cas reached over to the night stand and grabbed what Dean could only presume was left over lubrication, something Cas hadn’t needed since he met Dean. Dean watched as he squirted a lot on his fingers before he slid behind Dean and started to tease him with one wet finger. “Have you ever done this before?”

Dean craned his neck to look back at Cas. "No. Is… is that okay?"

“That is more than okay, Dean.” Cas gave him a soft smile. “I’m happy I’m the first. I’m going slow, but if you’re uncomfortable with anything I’m doing, please let me know.”

“I trust you,” Dean said, flashing him a sweet smile.

…. :::: :::: ….

“I trust you,” Dean said.

It was really nice to hear. Cas tried to relax and just enjoy the moment, instead of worrying too much as he slowly started to work Dean open. First with one finger, and after a while with two. He was going deep at first, but when the second finger slipped in with ease he experimentally rubbed over Dean's prostate.

The growled moan that escaped was encouraging. Dean pushed himself back on the digit. “Is this what you feel?” 

"Yes," Cas replied with a grin, loving that Dean was enjoying this. "Feels good, right?" He asked as he rubbed over it again.

“Yes,” Dean growled, his voice shaky as a soft groan escaped.

Cas didn't have an alpha cock like Dean, but he still worked in a third finger, just in case. He really didn't want to hurt Dean their first time doing this. "You're doing so good, Dean."

Dean hummed and pushed back. “I want to feel you.”

Yeah, it was time. Cas carefully removed his fingers and rubbed some lube over his already aching cock. He hoped he wouldn't come too quickly, but when he slowly pressed into that delicious tight hole, he had no idea how long he would be able to hold back. "Oh, fuck… Dean, you're so tight."

Dean threw his head back and clenched around Cas’s girth. “Breed me, Omega.”

"Fuck," Cas gasped out as he started to fuck Dean at a hard and fast pace. This was way too hot. Having Dean so submissive, saying things like that... Cas could feel himself reverting back to a brainless animal. "Yes, that's what you want?" 

“Yes…” Dean hissed as he arched up into the fucking, his breaths coming out in soft growls.

It was incredibly hot and Cas wondered why they hadn’t tried this before. He touched Dean’s knot in between Dean’s legs, massaging it softly. “Fuck, I can’t wait to feel you come around me.

Dean whimpered with need as he tried to fuck up into Cas's fist, all while impaling himself on Cas's cock. "Please…"

“Come for me, baby,” Cas growled as he wrapped his fingers around Dean’s shaft and started to stroke him as he upped the pace of his thrusts. He was so close himself and he knew he would come the moment Dean was pushed over that edge.

Dean practically howled when he came, clenching around Cas's girth as he painted their sheets.

The tightness pushed Cas over the edge as he filled his alpha for the first time. He was breathing hard as he stroked gently over Dean’s back, murmuring soothing words under his breath before he gently pulled out. He wrapped his arms around Dean as he pulled him into his arms. “Wow,” he breathed out. “How are you feeling?”

Dean turned to capture his lips in a kiss. "Completely and stupidly in love with you."

Cas smiled brightly at him, his heart skipping a beat. “I love you,” he murmured, pulling Dean tightly against his body. This was perfection.

…. :::: :::: ….

They did it. Sam had convinced a judge that Dean was safe to go wherever Cas did. He had even granted them permission for a mating bite. It was as though Dean had woken up in Oz after decades of tornados in black and white.

Dean was going to live his life, with a freedom so few alphas had, and so many Omegas took for granted. And he was going to do it with his mate by his side.

After a small celebration, Dean was helping Cas clean up the kitchen, and he couldn't stop himself from wrapping his arms around Cas from behind to pepper some kisses to his cheek.

Cas started to laugh, trying to escape. “Your stubble tickles,” he complained, swatting him with the dish towel.

Dean chuckled as he grabbed Cas and lifted him onto the counter, settling between his legs as he purposely rubbed his stubble against Cas's cheek.

"Ugh, no. Now I have tiny little holes everywhere," Cas complained with a laugh before grabbing Dean's face and pulling him into a deep and slow kiss.

Dean hummed into the kiss, gently cupping Cas's cheek as he did. When he drew back for a moment, he murmured, "I'm so happy."

Cas smiled at him, holding his gaze. "This couldn't have gone better today... We even can... You are allowed to claim me."

The pad of Dean's thumb dragged along the skin of Cas's jawline, his gaze dropping to Cas's pulse point. "I know… during your heat we talked about it. Would you actually want that?"

"I really want it," Cas breathed out. "And I want to do it traditionally. During my heat, I’ll let you hunt me and mount me... and bite when you knot me," Cas added, his voice sounding breathless.

Dean was pretty sure he fell in love with his Omega again in that moment. "Outside too?"

"Yeah. We could go camping in the woods. I have a pretty decent tent." Cas nudged his nose against Dean's. "What do you say?"

Dean nodded, drawing Cas in for another kiss. The images conjured were making Dean excited.

"My heat is in a few days," Cas hummed before he softly bit into Dean's lip. "Maybe we should start packing soon."

With a soft growl, Dean lifted Cas in his arms and started carrying him to the bedroom.

“Are you trying to pack me?” Cas laughed as he wrapped his arms around Dean’s shoulders, kissing his forehead.

"Don't be silly, that would make kissing you very difficult," Dean said as he pushed the bedroom door open with his foot and carried Cas to their bed.

"That's very true," Cas breathed out when Dean put him down on the bed. He gave Dean a heated look. "So packing for our trip, or practicing for my next heat?"

Dean grinned as he crawled over Cas to nudge his nose against his cheek. "Don't you always say practice makes better?"

Cas purred at him before nibbling at Dean's earlobe. "Yes, alpha. What exactly do you want to practice on me?"

Dean let out a soft growl, his knot already hard. "I want to watch you prep yourself."

Cas raised one of his eyebrows and gave him another heated look. "Alpha," he moaned before he added an innocent sounding, "Are you going to be my teacher?"

With a nod, he pressed a playful bite to Cas's cheek before he grabbed the lube from the nightstand. He held it up to Cas. "Yes."

Cas took it, chewing on his lower lip before he quickly pulled off his boxer shorts and spread his legs, angling his hips so Dean would have a nice view of his ass. He never stopped looking at Dean as he poured some lube on his hand and started to spread it over his ass. "I'm already very wet, alpha," he breathed out as he discarded the lube and pushed a finger into himself.

Dean couldn't help but groan in appreciation. "You might not need much lube then," he breathed out as he drew closer, "now slowly circle your finger, gently stretch yourself."

Cas did as Dean told him to do, moaning softly as he leaned back against the pillow. The look he was giving Dean was enticing as fuck. "Alpha," he whispered needily, probably knowing how much it was influencing Dean.

Dean leaned in, scenting Cas's inner thigh. "Add a second finger, Omega."

Cas easily worked in a second finger, the wetness making his hole glistening, the sweet scent pulling him closer like gravity. "Yes, alpha. Am I doing good?"

"So good," Dean murmured as he leaned in to lick up a bead of slick trickling down Cas's ass cheek. He groaned from the sweetness of his Omega's taste.

"Fuck," Cas purred as he scissored his hole open for Dean. "Alpha please," he begged in a broken voice.

The animalistic part of him won out as he gently pulled Cas's hand away and dove in, tongue first, lapping up the slick as he lifted Cas's hips a little higher.

"Fuck, yes," Cas gasped before he crossed his legs behind Dean's back, trapping him. "Alpha... take me, please."

Dean drew back, quickly shifting his position as he stroked his cock and lined himself up. "I love you," he breathed out as he pushed inside.

Cas gasped out, arching his back as his lips parted in lust. "I... love... you," he breathed out. "Fuck, you're so big."

"Maybe if someone had prepped himself longer," Dean gasped out through a chuckle as he slid in to the base. He couldn't help the growl.

Cas shook his head, biting down on his lower lip. "I love feeling you like this. Stretching me so much."

Dean groaned as he started fucking into Cas. "I love how tight you are."

Cas moaned loudly, clawing his fingers into the bedsheet before he lifted his arms over his head, bracing himself against the headboard. "Alpha, yes. Love feeling you for even days after you fucked me. Please. Use. My. Hole."

Dean growled and did as his Omega pleaded, fucking into Cas at a brutal pace, foreheads braced together. "I love your hole. It's perfect."

He could feel Cas's hot breath against his lips. "Fuck, I love the moment when you fuck your knot inside of me and fill my insides with your seed. Alpha, fuck. I need it hard this time. Please, just ram it in."

Dean growled and started fucking Cas faster. "You want my knot, use your hands to spread your hole."

His Omega whined in protest, but Dean didn't want to hurt him, no matter how much Cas wanted it. His hands left the headboard, reaching down before he spread his ass cheeks apart. His knot barely having any resistance now. "Please, breed me, alpha."

And Dean pushed inside, the tightness of his Omega's hole strangling the breath from his lungs and he couldn't hold back, he started filling him as Dean crushed their lips together.

Cas bit Dean's lower lip before licking over it with a groan. Dean could feel wetness in between them, the tightness around his cock and knot pulsing with the orgasm Cas was having. "Fuck," Cas breathed heavily against Dean's lips. "Love you."

"Love you too," he murmured, carded his hand through Cas's hair. 

…. :::: :::: ….

The weather was really nice. A warm early autumn day deep in the forest of a national park. No one was around them for miles. 

They had set up the big tent and camping stuff near a lake, spending some time fishing and cuddling at a campfire, roasting their catch. Cas felt at peace with himself.

He lifted the nose in the air, enjoying the scent of dry red and orange colored leaves and lush herbs in the wind as he winked at Dean. He could feel his hole getting wet, his own temperature spiking. His heat was about to start. 

Like a cat he meandered towards Dean, who was packing up the rest of their lunch into the cooler, shedding his shirt, and opening his jeans. He grinned at Dean as he froze, staring at Cas. Cas dropped his jeans and stripped his boxershorts, knowing the slick was already running down his leg. "I think we should test the skill of your nose. Count to twenty and then hunt me... alpha."

The dilation of his mate's pupils was answer enough, but he got a chill down his spine as Dean's nostrils flared and he let out a soft growl.

It gave him the adrenaline spike he needed before he started running into the woods. It was a glorious feeling, running naked through nature, the cooling wind on his way too hot skin. There was soft moss everywhere and it didn't take long for him to find a nice spot under a huge elm tree, where he knelt down into the moss and waited for his alpha to find him.

After a few minutes, he could hear the crunching of leaves, and the heavy panting of his alpha. Peeking through the brush, he could see Dean was naked too, his knot hard and cock leaking as he sniffed at the air. Then his head sharply turned in Cas's direction. Dean stalked forward, stroking his cock. "Omega," he growled.

Cas licked over his suddenly dry lips. He would never get over how fucking sexy and hot his alpha could be. It was hard to take his eyes off the big knot and cock. He turned around on all fours, moaning softly as he lifted his ass up high. Waiting for his alpha with a waiting, slick hole, ready to get bred and owned. He moaned again, just from excitement.

Then warm hands were roughly gripping his hips. Dean wasted no time in mounting Cas, his cock easily pushing inside as Dean's heated breath painted the nape of Cas's neck.

Cas cried out in lust, instantly started to fuck himself on his alpha's pulsing girth. The heat running through his body made his mind hazy with lust as he arched his back and moaned. This felt so right. "Alpha, my alpha."

"Mine," he growled in Cas's ear as he started fucking into him, his pace unbidden and ferocious.

"Yes!" Cas cried out, spreading his legs a bit further for his alpha before he reached back and grabbed his own ass cheeks, pulling them apart. "Fuck, alpha, my mate," he moaned, slicking even more with the thought of Dean finally biting him. Something he had longed for so long now. The longing had become unbearable in the past few days from Dean teasing his neck with his teeth everytime they had sex.

Dean howled as he shoved his knot inside, his cock filling him as his lips latched onto Cas's pulse point. He growled a hungry, "Mine," and then sank his teeth in.

Cas cried out in lust as he came hard. The pain from the bite was completely overridden by the orgasm that kicked in at the same time, the way his body pulsed in pleasure as he succumbed to Dean's claim. 

It was probably the longest orgasm he had ever experienced, and he knew he was out of it for a hot minute before he could feel Dean lapping at the bite. Fuck, it sparked a wave of more pleasure as he milked Dean's seed from his knot, deep inside of him. His alpha gave him a good breeding, satisfying his heat. "Alpha," he whined. "My pretty alpha."

Dean let out a breathy laugh. "You're officially mine."

Cas looked over his shoulder with a soft smile that quickly bubbled up into a laugh. He felt so light and happy. "Yeah, finally. It feels so perfect, Dean."

He knew this new bond between them was profound, changing them in a way that made it clear for everyone that they belonged together, making them attuned to each other even more now.

"How does it look?" he asked, bending his neck for Dean to show off his bite mark.

Dean groaned and another pulse filled Cas. "Like you belong to me," he growled. Dean proceeded to lick the mark.

The pleasure he received from Dean licking over the mark was almost as good as the feeling of him filling him again. “I do, Dean. We belong to each other.” He snuggled back against Dean, enjoying the way his strong arms felt around his torso.

“I finally feel complete,” he added after a moment, just enjoying Dean’s warmth and the familiar heartbeat against him.

"I will always take care of you," Dean murmured against the nape of Cas's neck. "Thank you for loving me."

Cas smiled and closed his eyes. "You changed me, Dean," he murmured. "You made me see the world in a new light." He sighed softly, his smile turning wider as the setting sun warmed his face. "I love you," he murmured happily, already excited for what would come next for them.

The End
