Chapter Text

Looking between the three alphas he couldn’t help but wonder how in the world he had gotten into this situation. There, standing before him was not only the captain of the first division Narumi Gen, but vice-captain of the third Hoshina Soshiro, and his friend Ichikawa Reno. They all looked like predators standing before their prey (him) and held expressions that gave nothing away to what they were thinking. It was clear as day that they were implementing their military bearing in order to make sure that he didn’t get overwhelmed when he made his choice, but still.... He could read them all like a book and from their scents alone and boy was it a tantalizing read.

“So let me get this straight,” He was still perched on the locker room bench that he had been on when they had cornered him after his workout, “You want to form a pack?” All of them nodded and he couldn’t help but point at himself as he spoke next. “With me?” Another series of nods. “Why?”

Admittedly the shyest of the group, Ichikawa shoved his hands in his pockets and looked bashfully at his feet. “Sir, to be frank, I’ve wanted this since we were both working with the cleaners. I just,” He forced his eyes to meet his and a blush covered nearly the entirety of his face, “I know I’m young. But I also know what I want. And now that everything’s settled with number nine I was planning to come to you alone. Then I saw your name on the registry for the pack signups and...” Ichikawa trailed off as he blushed even deeper. But before he could stutter through his confession again the vice-captain was taking his place to speak.

“Personally I’ve been wanting ya’ since I saw your score during the training exams.” He chuckled mischievously from beneath his breath, the sound making a shiver go up Kafka’s spine in what could only be described as a combination of arousal and dread. “I’ve been looking to settle down myself, family been on my ass too, but until recently I never felt a pull towards anyone until I met you. You’re such an idiot half the time that its endearing,” Though he was coming off cocky it was easy to see that he was putting on a show for the other two alphas beside him and in a way it made Kafka feel fond.

Standing in the middle of the other two Narumi scoffed as he crossed his arms over his chest, “You’re not the only one looking to settle down bowl cut,” He glared at the vice-captain before turning his attention fully to him and Kafka jolted slightly from the look of raw hunger in the captains eyes. “You may have known him longer Ichikawa and you may have been courting him the longest shit for brains, but there’s something that me and this omega have over here that neither of you do.” He monologued as if he was in one of his video games that he liked to play, and while it was slightly annoying, Kafka also found it hilarious and tried really hard not to laugh at his antics. “The bonds of a battlefield shared against a foe so powerful that it took an army to face them. The shared experience of loss and grief that can only be sated with one thing.” He wiggled his brows and now it was his turn to blush as he realized what the captain was about to admit out loud and there was nothing he could do to stop it as everything turned to slow motion around him. “A shared cycle.”

Oh that cocky son-of-a....

“What?!” Ichikawa and Hoshina shouted at once, their eyes practically bugging out as they took in what the captain said and Kafka started to move his hands around wildly so that he could explain.

“That was one time!” He could practically feel the heat coming off of his red cheeks as he shouted at the pink eyed alpha wearing a shit eating grin at the others. “It’s not what he’s making it sound like! I went into a stress heat during a mission cause someone decided to get us trapped in an abandoned drainage system in the middle of nowhere!” That was also how they had found out that his Kaiju form would not appear if his cycle was present because if he had been capable of transforming then they would have been out of there sooner. As it was, they had held out down there for three hours before Hasegawa saved them and force fed him suppressants. “And the most we did was you eat me out!”

“And it was the best tasting slick I’ve ever had in my life.” A salacious smirk spread over Narumi’s face as he made a show of licking his lips. “I haven’t been able to get you out of my mind since. More divine then the sweetest of nectars.”

“Lucky bastard.” Hoshina actually looked murderous at the captain but Ichikawa was giving Kafka the biggest puppy eyes imaginable with a look on his face that was determined in a way he only ever saw during training.

“I might not have done that before sir, but if you’ll let me I’ll happily do my best for you.” This made Kafka gulp and the other two alphas freeze as they took in his timid words. “Will you let me prove myself Sir?”

Kafka didn’t know what to do.

This was not what he was expecting when he signed up for pack registry. He simply was just looking to settle down now that he had accomplished his dreams (somewhat) and was getting even more up there in age. It wasn’t something that he talked about often, or really at all for that matter, but he wanted kids. He wanted to be a dad. And he wanted a partner or potentially partners if anyone was willing to give him a chance despite him choosing to register as late as he was. So when he had found out that the Defense Force held their own pack pairings to make it easier for their officers, he deliberated with himself for a tiny bit before saying essentially ‘fuck it’ and signing up. It wasn’t like he would be forced to agree to anyone that approached him after that. And while he had hope that someone would at least potentially find him desirable, he never thought he would get three alpha suitors interested, let alone these three in particular. “I’m gonna need time to think,” He admitted and this got the alpha’s to stop their bickering and pay attention to him once more. “I’m flattered, I promise I am, all of you are attractive and really good alphas, but it’s hard for me to see why any of you would actually want me in this way and I need some time to sort those emotions.”

It wasn’t a rejection, but it wasn’t acceptance either.

“Will you let us know if anyone else shows interest in you during this time?” Hoshina asked, and Kafka gave him a nod in agreement.

“And will you allow us to court you?” Ichikawa whispered as he twiddled with his fingertips nervously. And with a light laugh he agreed to that as well.

“Can I eat you out again?” Kafka threw his dirty sweatshirt at his face.

Chapter Text

The message was something that he really should have expected, but still... Kafka couldn’t help it when his brow twitched in annoyance. But, also blush as a wave of fondness washed over him as well. It was a confusing mix of emotions that’s for sure.

Gen – Officer Hibino your presence is needed post haste to my room where an important mission that only you can handle has been delivered right to my face. I will need you to come and sit on it quickly or I will have no choice but to find you and bend you over the nearest surface. You have five minutes before the whole base sees me give you my knot!

Followed by the lewd message was a picture of the first division captain himself with his tongue lolled out and him laying down on his futon shirtless.

That alpha was going to be the death of him.

He hadn’t even given everyone the full ‘okay’ yet for courting him. And already he had Reno sweetly bringing him gifts every morning as if he was some sort of Victorian maiden in need of being wooed. The innocence of his youth making him romantic in the gentlest of ways. But also chaste as fuck. Soshiro on the other hand still treated him as usual but was more... helpful? Kafka wasn’t sure how to describe what the vice-captain of the third was doing. Like there was a sudden difference in their dynamic but there also wasn’t and while it was confusing it also made a hell of a lot of sense given who the alpha was. Any time he needed anything it was suddenly within palms reach and things that he had been putting off replacing or even buying because it seemed too frivolous to buy at the moment was mysteriously at his door with the alpha’s scent all over it. He was clearly the ‘provider’ type out of the three. Always watching and giving. And then there was Captain Narumi. Out of all of them he was a different breed all together and at times it was overwhelming but others... it was kinda refreshing.

Where Reno was sweet and straight out of a romance novel, Gen was lewd and eager to get his hands on him which – admittedly – made him feel good considering his lack of confidence in his body that he’s had for the majority of his adult years. And where Soshiro was a silent provider who didn’t show too much emotion behind his mask of mischief and subtle authority, Gen was loud and blunt with his emotions. Never holding back even when his remarks could be scathing. It was like the three balanced each other out with how they acted and while Kafka knew deep down that he already had his answer.

He still was reeling from the fact that these three alphas wanted him.

Being a male omega in a society that still held a lot of patriarchal views from long ago was difficult to say the least. Not to mention all of the homophobia that came with it and expected gender roles on top of that. It made growing up hard. Especially when he and Mina had been orphaned. He had gone through a lot and had to grow faster than he was ready to in order to keep all those that he cared about alive. All of this made him undesirable to a lot of alphas. He was too independent. Too strong willed. Wasn’t willing to adopt the role of a traditional omega and assume the position of a ‘woman’ (like gender was that easy anyway) just because of what his sub-gender was. So he was having difficulty understanding why they would want him.

They were successful, strong, powerful, and considered some of the most eligible bachelors in Japan. Then there was him... Kafka Hibino.

“Times up.” A voice whispered from behind him and suddenly he had the captain wrapping around him like an overgrown koala as he groped at his chest.

That was another thing that was still surprising him.

The touches.

After their talk in the locker room where the three had declared their intentions with him, the captain had singled him out alone and asked him for consent to ‘touch’ him and prove that he could satisfy all of Kafka’s urges. Everyone knew that omegas had higher sex drives than alphas (which is why they typically had more than one) and he wanted to show him that he could rock his world so to speak with or without the others help. It wasn’t unheard of before a courtship that potential mates did this. So he had agreed.

Sue him, the captain was hot and the last time he had been touched in any single way had been when said alpha had pinned him to a wall and proceeded to drink his slick as if he was a fountain that he had found in a desert after going without for a week.

“You didn’t even give me enough time!” He complained, “I just got your message.”

“Woops,” Gen licked his scent gland before nibbling everywhere around it. “What can I say officer Hibino, this is a matter of life or death. So come on, hop up. You’re using my face as a seat cushion right here since you didn’t meet the time limit.”

Looking around where he was standing rapidly, Kafka felt all of the blood rush to his face in embarrassment as he was essentially manhandled onto the floor of the first divisions makeshift library. No one was there thankfully, but there were cameras and as he was being manhandled he flailed a bit as he attempted to point them out to the uncaring captain. “Don’t worry,” He smirked dangerously as he practically ripped Kafka’s pants off of his body despite how he wiggled around like a fish out of water. “I already disabled them before getting here. And everyone knows that I’m courting you with bowl cut and Ichikawa so this is par for the course. If they dare to walk inside I will just have to show them what they will never get to have.”

“I never agreed you greedy alpha,” More complaints fell from his lips even as Gen got into position on the floor and practically picked him up in order to have him straddle his head and neck.

With a roll of his eyes he smacked his ass hard, the sound ricocheting around the room loudly and making him nearly fall over himself as he balanced over the alpha’s face. “Like you were going to ever refuse.” He rolled his eyes at him from between Kafka’s legs and gave his ass another swat for good measure as he continued to speak. “You think I can’t tell how you feel omega. That I can’t tell that you’re dying to say yes but are scared for whatever reason is floating around your head.” He froze at being caught and made a loud eep noise as this time Gen groped both of his ass cheeks with his hands and squeezed them like stress balls. “I already know that it’s a yes so let me make you feel good and let us show you how well we can love you idiot.”

Kafka sighed. “I just, still don’t see why you, Soshiro, and Reno would want me. I’m me. There’s nothing really special here and I’m older than all of you. Not to mention that you three would be mated to each other after this as well and I know that you and the vice-captain don’t really get along. So why, why pick me when all of you could have a prettier more gentle omega by your sides.” The words spilled out of him without thought and slowly he scooted down onto the floor beside the alpha who was looking up at him with surprised wide eyes.

“You really are an idiot,” The alpha muttered to himself before sitting up with a sigh and placing both of his hands on Kafka’s cheeks. Then in the sweetest gesture the captain had done thus far he leaned his forehead against his and basically cradled him close. “Kafka, you really don’t see what everyone else around you see’s do you?” It wasn’t really a question, more of a statement, and all he could do was listen as the alpha continued. “You’re extremely kind and protective to a fault. It constantly scares me that you’re going to do something dangerous someday that I won’t be able to save you from because of just how big your heart is when it comes to protecting everyone above yourself. But that’s also what’s made me start to fall in love with you.” Kafka’s heart was threatening to beat out of his chest from how hard it was beating due to the others words and never in his life had he ever felt as overwhelmed as he did right now. “On top of it all your goofy and see so much positive in the world and in others that its absolutely infectious. It honestly makes me sick sometimes because of how much of a realist I am. But that’s why I feel you are the best omega I’ve ever met. Every part of you makes me not only want to be better as an alpha, but as a man and captain as well. I might not be able to speak for the others, but as for me, I never wanted to settle down until I met you. For the first time in my life I can see myself having a future with someone and I’m willing to put my differences aside for Hoshina in order to do that. So stop feeling insecure and use me as a stool.”

Kafka didn’t answer him. Instead, he brought the alpha into a heated kiss. By the time that he pulled away they were both panting and he knew that it was time to just bite the bullet. “I’m scared. No ones ever treated me this way before and I’m not used to it. But, for you and the others I’m willing to try.” Fingers linking together he shyly kissed Gen’s nose. “Can you text Soshiro and Reno to let them know that I’m done thinking and giving you all the go ahead for us to start working on the dynamics of our future pack?”

A Cheshire smile that was filled with mischief spread over the captains face. “Oh I have just the idea on how to do it as well.”

****

Soshiro’s phone beeped repeatedly from the group chat that he had formed with captain Narumi and Ichikawa so that they could update each other when it came to Kafka. Without thought, he opened the chat when he saw that it was a video message and figured that it would be the usual lovesick rant that the other was known to drop in on them when his eyes widened comically from where he sat at his desk. “What the-“ There, on his phone, was a video playing of that fucker tongue deep in Kafka’s ass as he sat on the captains face and moaned loudly from where he sat.

“Guess who’s given us the go ahead. Too bad you two aren’t here, guess I’ll have to feast on our omegas delicious ass all by myself.” Narumi was taunting them. And while normally he wouldn’t let the man get under his skin... this was an exception. “Pretty baby’s been insecure so that’s why he hasn’t said ‘yet’ till now.” The Narumi in the video continued as slick dripped onto his face everywhere and he held Kafka’s thick cheeks open for him to see how he winked at the camera in arousal. “If you’re not careful I might have to make him think that I’m the only one dying to knot him.” A finger was teasing at Kafka’s rim and a part of him was internally begging for Narumi to stick it in and make the omega beg.

Another though... it made Soshiro leave his seat and call Ichikawa before heading out the door of his office.

Chapter Text

As much as Reno and Soshiro had wanted to touch him that day that Gen decided to cause havoc in the group chat, inevitably because of a smaller kaiju attack it didn’t actually happen. Which made the alpha at the first obnoxious in a way that Kafka couldn’t tell if he liked or hated. On one hand he liked this boyish teasing that he did with the other two alphas. On the other...

“Do you really need to take more pictures?” A heavy blush was over his cheeks and Kafka couldn’t help but wonder what his life had become. “Don’t you have enough already?”

Without even an ounce of hesitation Gen answered him. “Never. I’ll never have enough.” And boy didn’t that do some things to him. “Besides,” His long fingers hooked upwards towards his prostate in order to make him squirm at the same time as the alpha leaning down with his phone to get a close up of his slick hole being stuffed full. “Gotta show the boys what they’re missing out on. Poor Ichikawa’s virgin disposition can barely handle it.” He snickered teasingly knowing damn well that his voice was coming in on the video feed. “Bowl cut on the other hand,” Fingers slipping out of him Kafka could feel as Gen pulled at his rim in order to make him gape a little so that the other two alpha could get a good look at his insides. “Lets see how long it takes for him to crack.” He ended the video there and clicked a few places on his phone – most likely sending it in the chat – before removing his fingers entirely and replacing them with his cock instead.

The quick action made Kafka throw his head back in pleasure as a filthy moan left his lips. Up until a few days ago they had never fully gone all the way but after a couple hours of being teased he had finally caved and practically begged the alpha to take him. Gen had no problem delivering to his pleas and also had no problem teasing the others that he was first to get at his ass. It was kind of hot to see how flustered Reno and Soshiro got in their own ways. But he also couldn’t help but feel like a storm was brewing just beneath the surface and Gen’s teasing was going to come back to bite him on the ass instead of the alpha.

“Always feel like heaven,” Gen threw his head back and wasted no time in grinding his cock against Kafka’s prostate. The man was a master with his hips. Seeming to know how to move in the most sinful of ways in order to drive him insane and make him a pliant noisy mess. “You’re so perfect.” He praised and this made Kafka’s inner omega go pliant as the alpha maneuvered him so that his legs were spread wide. “No one will ever feel as good as you.”

Just as all of the thoughts started to filter out from Kafka’s mind as he became drunk on the way that Gen moved his hips, the door to the room flew off its hinges causing both of them to stop. Before he realized what he was doing, he had pulled the alpha’s cock out of him and transformed fully as he got in front of Gen and roared at the threat. His instincts were going haywire as his inner omega started to take over and for a moment he couldn’t hear anything, let alone fully see what was in front of him until Gen’s frantic yelling brought him back and he realized who he was staring at.

Kaiju form falling off of him he sunk heavily onto himself. “What the hell!?” He shouted, “Don’t fucking scare me like that you jerk!” There, standing before him in number 10 suit and whimpering like a kicked puppy, was Soshiro. The kaiju tail was wrapped around one of his legs protectively and Kafka instantly felt bad. Using his speed he pushed off of the bed and pulled the shorter alpha into a hug. “I’m sorry for snapping. I didn’t realize it was you and my instincts screamed at me to protect right then because Gen and I were vulnerable.”

Voice small, Soshiro pressed his red face into his chest and snuggled there almost like a pup, “I’m sorry for startling you. I was pissed because Gen gets to touch you whenever he wants when I haven’t been able to yet and I just, reacted poorly and kicked in the door to tell him off, and didn’t think about how you would react.” Omega’s weren’t exactly known for being kind when interrupted during sex, so Soshiro really should have thought before he acted. As it was though, Kafka was just glad that the kicked puppy scent was leaving him and he relaxed in his arms. For a terrifying second there he thought that he fucked up and Soshiro was going to leave. But he had stayed and allowed him to comfort him like this.

Eyes finding Gen’s he could see the genuine worry in his eyes as he started rearranging the nest they had made frantically as if he couldn’t control himself. His reaction must have scared him too. It made Kafka gulp heavily. “Let’s go to the nest alphas.” As he spoke he ushered Soshiro to the nest before picking him up and depositing him in a surprised Gen’s arms. The two simply looked at each other in shock before watching him go back to the door and placing it in the doorframe and steadying it as best as he could before coming back. “I think it’s time for us to cuddle and scent properly. Reno isn’t here but I want at least two of my alpha’s scents on me.”

Obediently they listened, their hind brains coming to the surface as they did as he asked of them and got on either side of Kafka’s body as he sat in the middle of the nest. Surprisingly, Gen was putting out comforting pheromones towards Soshiro and rubbing the scent gland on his wrist on the smaller alpha’s neck. Of which, Soshiro actually reciprocated.

It made Kafka’s brows raise, but he found that he liked this. Liked that the two were interacting with each other in this way. And while a lot of it was probably instinctual since he did kind of go feral to protect Gen when he thought that a threat was interrupting them, it was hotter than he ever could have imagined. So hot in fact that he started to leak slick and he remembered that he was completely naked. In fact the only one who had clothes on was Soshiro. “I told you that this was a bad idea.” Number ten complained from Soshiro’s chest and the three practically jumped at his sudden speech. “This wouldn’t have happened if you hadn’t have agreed to share the omega with the other alphas. Three alpha’s mating with one omega is ridiculous.”

“Shut it you tin can,” Gen argued, “He’s mating me two you asshole!”

This made all of them pause. “I am?” Soshiro’s voice was back to its teasing lilt it normally took but the softness still lingered.

Gen blushed heavily at what he had just admitted and Kafka could only watch in amazement as the two talk, a lightbulb going off in his head. They didn’t just want him. They wanted each other as well. It made sense. He just hadn’t thought about it yet and the thought shouldn’t have made him as horny as it did but seeing two alpha’s together felt like a naughty chaotic dream come true. It also made him feel like they were corrupting Reno but they would cross that bridge when they eventually got there. “I mean,” The pink eyed alpha stuttered, “I-“

“I’d like that.” Kafka admitted in hopes of breaking the ice. “If you two, well three since Reno is part of this too, were mated to each other too.”

Soshiro’s eyes were fully open and his mouth was gaping like a goldfish as he stared back and fourth between him and Gen before gulping heavily and blushing even harder. He was silent as he nodded to himself and then without hesitation he started throwing number ten off of his body outside of the nest. “Captain,” Kafka couldn’t think of one time he had ever heard Soshiro call Gen that and now he was dripping, “Kiss me.”

There was no hesitation. Just two alphas coming together and kissing messily in front of him and Kafka was going to explode. When they finally pulled apart from each other their eyes were heavy and each of their throbbing lengths were erect. Both were similar in size and Kafka squirmed. He needed them in him now.

Like right now.

Seeming to be able to tell what he was thinking, both stared him down and seemed to be sharing a telepathic conversation before smiling chaotically like the demons that they were. “Soshiro,” Gen grabbed the back of the other alpha’s head by his hair and pulled as he spoke, “You wanted a taste of our sweet omega right?” The vice-captain nodded his head rapidly and without thinking, Kafka spread his legs. “My cock was just rearranging his guts, why don’t you get your tongue in there and tell me how we both taste?”

Gulping visibly, Soshiro whispered a, “Yes sir,” and then fell between his spread legs and without a ounce of hesitation pressed his face to Kafka’s messy dripping hole to swallow his slick. A loud moaning growl fell from the smaller alpha’s throat and he threw his head back in pleasure. Unlike Gen, Soshiro was a messy eater. He was constantly moving. Seeming to trying to get every trace of him that he could with his tongue as he moaned and drank his fill. All he could do was hold onto his hair with both hands as he moaned in pleasure. It was hot. And when Gen got behind the other’s back and spanked his ass lightly Kafka felt like he had died and gone to horny heaven. This had to be a dream. There was no way this was real.

But as Gen scooped up his slick to use as lube and started to finger Soshiro open he could feel just how real all of this was as they all started to lose themselves in the pleasure of it all. All of them were moaning loudly and obscenely. And the dirty talk. The stuff that spilled from the captains lips with ease was absolutely sinful. “Should have done this years ago.” Fingers battering at Soshiro’s insides the alpha got even more crazed as he rimmed Kafka with gusto. “Should have bent you over and given you my cock to shut you up sooner. Always walking around like you are the head alpha in charge. But really all you need is this isn’t it. Your pretty face in our omega’s slick hole with me prepping you to get fucked. That what you want Soshiro, want me to fuck you too? That’s why you rushed here as quick as you did isn’t it? Why you busted down my door. It wasn’t cause you were simply jealous about me touching Kafka more than you. No you wanted me too didn’t you.” He spanked the smaller alpha hard and a loud keen fell from Soshiro’s lips as he hooked his arms around Kafka’s thighs and practically sucked the slick out of him as his eyes rolled to the back of his head. “Admit it and I’ll give you what you crave!”

“Yes!” He shouted, his voice cause him to vibrate his lips against Kafka’s taint. Soshiro was a complete mess and before he could beg more Gen had thrust inside of him with Kafka’s slick still as their only source of lube and he was being yanked back against the captains’ chest. “Fuck!”

“Ever been fucked before Soshiro?” Gen wasn’t going easy on him at all as he snapped his hips roughly against the others skin. “Feels like you have had a lot of practice here alpha.” Soshiro couldn’t even answer as his cock bobbed against his stomach and Kafka’s slick dripped from his face and chin to splash against his body. “Omega,” Gen called, “Help our baby get his cock inside of you.”

Scooting down the bed, Kafka did as he was told and soon Soshiro was slipping in. He filled him out so well and the three were moving recklessly on the bed. The nest was falling apart and moans filled the air. It was noisy, messy, and everything that he could ever hope for. And when Soshiro inevitably knotted him, causing them both to cum, Gen pulled out and spread his release all over their bodies to mark them as his.
