Chapter Text
The witch grabbed her spell book and jumped through the window before the Winchester brothers could burst in through the door. She landed on the ground smoothly and made a run for it. She heard footsteps behind her and ran even faster. He looked behind her then looked back. A man with a gun stood in her way. He aimed it at her and shot her a couple of times. She was able to dodge the bullets but just barely. She glared at the man and muttered a spell under her breath. The man’s eyes widened, and he crumpled to the floor with a loud groan. He clutched his belly and whimpered softly as the witch got away.
Dean knelt down beside Castiel while Sam went ahead of the pair. “Hey, Cas. Look at me, baby.” He patted his cheeks a couple of times and frowned when he saw tears. Castiel cried quietly and curled on himself. Whatever spell the witch cast on him was giving him bad stomach cramps. “Stay with me, Cas. You’ll be alright.” Dean’s voice wavered as he rubbed Castiel’s back. Castiel felt around for Dean’s hand until he found it. He squeezed it tightly and Dean had to bit back his protest. He was most likely going to break Dean’s hand.
A few minutes later it was over. Castiel slumped on the ground and let go of Dean’s hand. He sighed quietly and wiped the tears away. The pain went away just as Sam came back empty handed. “She got away,” he announced with a frown.
“She did something to Cas.” Dean said as he helped Castiel up who practically cling to him. He patted his back awkwardly and just let it happen. Even when they walked back towards the car. The brothers were listing down any possible spells the witch must’ve cast on Castiel. He was extremely quiet while they talked. They knew he was quiet just not this quiet. When Dean tried to pull away from Castiel the newly human’s grip tightened on him. “Uh...Cas. I have to drive.”
Castiel looked up at Dean then at the car before letting go of him. He looked down at the ground as he shuffled towards the impala and climbed into the backseat. The brothers looked at each other in confusion. Dean was mostly worried. He would ask Castiel when they get back at the bunker. Thankfully the witch was close by their place. They climbed into the car and Dean drove them back to the bunker.

When they arrived, Castiel immediately made a beeline towards the kitchen. He looked through the cabinets and drawers until he found what he was looking for; the Nutella. He grabbed a spoon and opened it before dipping the spoon in to eat the chocolate. Dean followed the newly human and raised an eyebrow when he spotted him covered in chocolate with an empty Nutella bottle in hand.
“Are you okay?” Dean walked closer and took the empty bottle and spoon away from Castiel.
“No.” Castiel blurted out as he opened the freezer and grabbed the tub of ice cream. He wrenched it open and grabbed another spoon. A much bigger one to scoop up the ice cream and eat it. Some of it dripped out of his mouth. Dean made a dirty face and shook his head.
“There are plates, you know.” Dean tried to take away the ice cream, but Castiel turned his back towards him.
“I’ve been craving sweets since I got into the impala. Now that I have it I won’t let you take it away from me.” Castiel hissed at him and cradled the ice cream.
“Fine. Are we going to talk about the spell the witch cast on you? Did she make you hungry or something?” Dean chuckled. “That would be funny.” Castiel stared at Dean in silence before bursting into tears. Dean was so surprised he stood there in shock for a few seconds before the gears in his head started to car. “Cas what’s wrong? Are you okay?” He grabbed Castiel’s biceps and frowned at his puffy face.
“Y-you laughed at me!”
“What? No I wasn’t! I wasn’t laughing at you, baby.” Dean wrapped his arms around Castiel and hugged him tightly. He ignored the cold ice cream in between them and rubbed Castiel’s back gently. They stayed there and Dean tried not to pull away from how cold his belly was getting from the ice cream.
Once Castiel was calmed down he pulled away and handed Dean the tub of ice cream. “I’m going to shower.” He wiped the tears away and left the kitchen. Dean glanced between the ice cream and Castiel walking away. He was trying to figure out what the hell happened.
He didn’t have to wait long since he heard Castiel scream out his name. “Coming!” Dean called out as he placed the ice cream back into the freezer before walking towards the bathroom. He knocked on the door and Castiel opened it. He grabbed Dean’s arm and pulled him in before slamming the door shut. He had a towel wrapped around his body and his cheeks were flushed. “What happened?” He asked slowly as he stared at Castiel who looked embarrassed.
“I-I think I know w-what that witch did to me.” Castiel whispered as he stared at the wall behind Dean.
“Okay. Well, what did she do?” Dean raised an eyebrow.
Castiel frowned and sighed quietly. He tugged the towel off and let it pool around his ankles. Dean was still confused until he lowered his eyes towards the problem. So many thoughts were going through his head. “Oh, you’re on your period.” He blurted out without thinking.
Castiel grabbed the towel and wrapped it around himself again. “Dean! This is serious! I have a vagina! A bleeding vagina! I’m going to die!”
“Calm down, baby. You’re not going to die. The bleeding will go away next week. If you’re lucky then in a couple of days.” Dean smiled awkwardly. He tried to stay calm so that Castiel wouldn’t freak out. This isn’t the weirdest thing he has seen before. “Just take a bath. You’ll feel much better.”
“You’re going to take a bath with me though.” Castiel said as he started to take off Dean’s clothes before a hunter could say a word. He just like it happen. Whatever to make Castiel happy.
The next few days was tough for the pair. Dean had told Sam about the problem and the younger Winchester was looking for the witch while Dean took care of Castiel. He got stuck in watching chick flicks and trying to take away food from Castiel because the man kept stuffing his face every hour of the day. The worst part of the day was seeing Castiel staring at a wall with a blank expression. It meant he was thinking about the dark thoughts lurking in his mind. During those times, Dean made sure to not leave his side. Not even for a second. Castiel kept him up late because of how clingy and a cry baby he is, but Dean wouldn’t change anything about their time together.
One day, Sam went out on his own; stating he had a lead on the witch. Dean and Castiel were snuggled up in Dean’s bed watching a movie. Castiel was getting bored of the movie and wanted to do something else. He always loved watching new movies with Dean but not right now. He was horny. His stupid hormones must be acting up now. He was done with his period two days away. It didn’t last very long thankfully. Castiel didn’t think he could’ve survive much longer. He glanced over at Dean who was engrossed with the movie. He turned his back towards the hunter and laid there for a couple of seconds. When Dean didn’t notice he covered his body with a blanket and shoved a hand down his sweatpants. He rubbed a dry finger against his pussy and bit back a moan.
Castiel was much more sensitive with a vagina he learned quickly. He was already soaking wet. He pushed a finger inside himself and covered his mouth with his other hand. He rubbed his clit and bit down on his hand to keep from moaning so loud. He started to rub the clitoris with two fingers which sent a shock throughout his body. It felt so good he didn’t want to stop. He was so out of it he didn’t notice the bed squeaking until Dean tugged his hand away from his mouth. Castiel’s eyes snapped open, and he looked into Dean’s green lustful eyes. “Hey, baby. Having fun without me?” Dean smirked.
Castiel blushed and broke the eye contact with Dean. He wasn’t even sure if Dean would do any sexual activities with him being...different. He looked back up at him and smiled nervously. “S-sorry. I didn’t think you would want to do anything with the current situation…” He tried to pull away but Dean’s grip tightened.
“Don’t think like that. I don’t care how you look or what you have. I love you for you, and who knows; maybe this can be one of our kinks.” Dean wiggled his eyebrows suggestively and grinned. “Less money to buy lube since a vagina self lubricates.” He winked.
Castiel blushed even more and nodded slowly. “I suppose…”
“Just tell me if you don’t like that, okay?” Dean raised his eyebrows and waited for Castiel to nod. He tugged off the blanket and stripped them out of their clothes.
Once they were naked Dean reached a hand in between Castiel’s thighs and start to play with his pussy. Dean’s fingers were skilled when they rubbed against his cunt. Castiel’s legs started to shake in anticipation, and he moaned loudly. He was leaking by the time Dean started to thrust fingers inside his pussy. He screamed and arched his back when Dean prodded his G spot. “Dean!” He sobbed as he gripped the sheets.
“Feels good doesn’t it?” Dean asked. He pulled his fingers out and coated his cock with Castiel’s juices. He pushed Castiel’s legs towards his chest and slapped his cock against his pussy. Castiel’s hair stuck to his forehead and his legs were shaking in the air. Dean teased his slit for a bit before pushing into him. He moaned loudly. “Your cunt is so tight, princess.” His thrusts were smooth with the fluid Castiel’s pussy was providing. High pitch moans were fucked out of him.
“Dean! Deeeeeaaan!” Castiel cried out. He gripped Dean’s arms and felt his walls clench around the hunter’s cock. He threw his head back against the pillow and panted heavily. When Castiel came his body started to shake when Dean kept assaulting his G spot. “Ah! Ahhh!”
Dean came inside of Castiel with a groan and left his soft cock inside him. Castiel felt Dean’s cum fill him up and leak out of his pussy. He had a dazed smile on his face as his eyelids started to droop. He felt Dean kiss his forehead and sighed quietly.

8 months later.
“Where is my ice cream?!” Castiel called out to Dean. He had been craving it all morning and the stupid hunter still wouldn’t give it to him. Dean walked inside the room with a bowl filled with ice cream and sat down on the bed to feed Castiel. He leaned forward and wrapped his lips around the spoon. He moaned as the cold ice cream flooded his taste buds. He rubbed his big round belly and hummed.
Sam never found the witch which meant she couldn’t undo the spell. Castiel didn’t seem to mind because he was rubbing his round belly lovingly. If Castiel was happy then Dean was happy. Even though he had to feed Castiel whenever he demanded it. He didn’t mind though. Once Castiel was done with the ice cream Dean set the bowl down and stood up to kiss Castiel. He sighed quietly and kissed him back.
“Dean?” Castiel whined. “They hurt again.” He looked down at his big breasts that were filled with milk for their baby. They started to grow when he found out he was pregnant. Dean thought it was odd at first, but eventually the both of them thought it was a miracle. They were going to be a family. Something they always wanted.
Dean smirked and helped Castiel out of his shirt. He rubbed over his belly before leaning in to lap at his nipples. Castiel moaned quietly and slid his hands into Dean’s hair. The hunter wrapped his lips around a nipple and sucked on it. Milk flooded his mouth, and he drank it up eagerly. Castiel moaned quietly and tugged on his hair gently. Dean moaned onto the other nipple and teased it with his teeth gently. He also sucked the milk out of that breast and drank it all. He kissed Castiel’s chest and moved towards his neck and finally his mouth.
“Better?” Dean murmured.
“Yes. Much better. Thank you, Dean.” Castiel smiled lovingly at him.
