Chapter Text
Dean had been laying in bed for the past 6 days, watching crap TV and ordering food to his hotel room. The advert didn’t lie when it said it would pay handsomely. His bed was covered with empty burger wrappers, a half eaten pie in his lap. If he was being truthful, he was filling the void that the labour had left. He missed his stomach, even if he only had it for an hour, maybe next time he’d had it for longer. He shifted as he thought about being pregnant again, he’d go back to the doctor’s office tomorrow, bright and early, let Cas and Rowena do whatever they wanted to him. He would happily take it all so long as he got his stomach back.
He should shower before tomorrow he was sure he would stink. He got up, off the lush bedding and brushed the crumbs off his stomach. Fuck, he was still slim as ever.
The next day, Dean wore the baggiest slacks he owned. He drove back down Doctor Novak’s Clinic and stepped through the doors at precisely 7am.
“Dean!” Gabriel beamed, he was sporting a small bump that made him look 6 months pregnant. He got over to Dean as quickly as he could, hugging the taller omega. “You came back. I knew you would. I knew you’d like it.”
Dean smiled as he hugged Gabriel back, “and I can see you’re already expecting.” He laughed as he placed a hand on Gabriel’s budding stomach. “When did you get pregnant again?”
“Oh last night. Cassie says I’m going to have even more than last time. But we’ll only find out in 9 months time.” Gabriel smiled. “Come on, I’ll take you to Cassie. He’s been nervous to see if you’d return.”
Dean smiled as he allowed Gabriel to take his hand and lead him back down the familiar corridors. He led him into a new room, stacks of old leather-bound books littering every surface, and Cas sat in the middle, furiously reading and taking notes.
“Cassie look who I’ve got!” Gabriel almost sang.
Cas jumped as he was startled out of his concentration, but his face soon softened as he saw Dean.
“Dean.” He said, as he stepped around the table and over a small pile of books. “So you’re wanting another go?”
Dean nodded, as Cas pulled him into a hug. He smelt of petrichor and sylvichor. Fresh soil and earth.
Springtime.
Dean leant into Cas for longer than he needed to. It felt good to be in Cas’ arms. It felt right.
“So,” Cas said, finally pulling away. “Let’s take a seat and we’ll discuss the next experiment.” Gabriel clicked his fingers and three tall, leather armchairs appeared around them. They took their seats, Gabriel rubbing his stomach, whilst Dean listened to Cas.
“You’re going to have the same as Gabriel this time, if that’s alright. We’ll give you Rowena’s potion, and er... fertilise you. You’ll carry multiple pups. More than average. We’ll aim for 5 pups, but with you naturally producing twins, and it not being perfected yet. That’s what Gabriel’s for-” Cas smiled patting Gabriel’s knee. “We can’t confirm how many you have until you’ve given birth. It’ll be a 9 month program, just like a typical pregnancy. We’re happy for you to stay here at the clinic or rent a place nearby, but you’d need to come in for regular checkup and if you start to struggle to walk we’d put you on bed rest here at the clinic.”
Dean nodded, listening. It would be nice to have his own place and be able to do as he pleased for the majority of the pregnancy, but he didn’t think he’d be able to go through it without Gabriel or Cas by his side.
“I’d like to stay here. I don’t think I can do it myself. But I’d want my own independence too. I’d want a job around here.”
Cas nodded. “We’re happy for you to do that. We can talk to Rowena about how to you can help with the potion making or anything else if you’re not happy with that.” He offered.
Dean smiled. “That sounds like fun.”
“Okay,” Cas beamed. “Do you have any other questions before we get you pregnant?”
“Just one. I know that Rowena’s a witch, and Gabriel said that you two aren’t witches. But you’re doing magic. What are you?” He asked.
Gabriel laughed as Cas took a moment to think how to answer.
“You’re Dean Winchester. You were a hunter. Maybe you’ll go back to that one day. Your father, for almost your entire life has been hunting a demon. A yellowed eyes demon. We’re just like that but the inverse.”
Dean frowned, the inverse of demons were angels. But they didn’t exist. They couldn’t. Not with everything shitty happening in the world. With the rape and the wars. If they were real then so is God and God with his omniscient wouldn’t allow it. No. They’re not angels.
“Dean, why don’t you believe?” Cas asked, cocking his head to one side.
“They can’t exist. You can’t exist.”
“But you readily accept demons.”
“Demons make sense. With all the bad in the world.”
Gabriel sighed, Dean would never believe without proof. He stood up and shrugged. Lightening crackled and the lights dimmed as shadows of wings grew from Gabriel’s back. They were large, almost filling the room, but they were also bent, Dean noticed. Some feathers were tangled whilst others were missing and one wing hung lower than the other.
Dean gasps, not realising that he was reaching up to stroke them until Gabriel pulled away, his face contorted with fear and pain.
“I… I’m sorry. I didn’t mean to-“
Gabriel shrugged again, and his wings disappeared, before leaving the room.
Dean looked to Cas. He really didn’t mean to hurt Gabriel, he just wanted to comfort him, help it. It had looked painful.
“Hey it’s okay. Gabriel’s been through a lot. He’s sensitive about his wings. They’re the one thing about his body he doesn’t like. You should be happy that he allowed you to see them at all.” Cas explained softly. “He trusts you.”
Dean nodded, but he still felt like shit. “Does that mean he’s the Angel Gabriel. Mary and Jesus and all that?” He asked trying to change the subject.
Cas chuckled softly. “Yeah. He was so proud of that job.”
Dean smiled softly. “I’ll find a way to make it up to him.”
“I know, I also know he’s not upset with you. He just needs some time.”
Dean nodded, happy with the reassurance. “So, are you ready to impregnate me, angel?”
Cas chuckled as he stood, leading Dean out of the room. “Angel, I like that.” He commented as he led Dean back to the makeshift hospital room.
Dean pulled off his pants and underwear, before climbing onto the bed. He sat up, as he waited for Cas to come back with the potion.
“So you don’t have an omega? You’re not claimed?” Dean asked Cas after drinking the potion.
“No, I don’t think I could do it. I’m thousands of years old. I’m going to live for thousands of years. Angels are my brethren I could never claim one, I could never have sex it would be… incestuous. And humans are just too short lived. I want to mate for life.”
Dean nodded. He couldn't lie, he was upset with that revelation. He had wished that Cas would claim him as his own. He wanted to be with Cas for the rest of his life, but he understood why Cas felt the same way.
He shuffled down the bed, laying back as he looked up at Cas between his legs.
“Could you fuck me first?” He asked. “I liked imagining that it’s your pups. And… what you did to your cock last time-"
Dean had masturbated more than once to Cas’ growing cock, he had never felt anything like it. It made him want to be a cock sleeve. Cas hummed a response as he got undressed, the dildo laying on the bed. He climbed onto the bed, straddling Dean’s hips as he nuzzled Dean’s neck. He smelt like apple pie and cinnamon.
He sucked on Dean’s neck, trying to taste the delicious scent. Fuck he tasted good. His cock twitched as he kissed up to Dean’s mouth, pressing his tongue forward, into Dean’s mouth, exploring and tasting and dominating. Dean moaned into Cas’ mouth, allowing his to take all control. His fingers scratched on Cas’ back, trying to get some purchase.
Cas grabbed Dean’s wrists, pushing them up above his head, pinning them there. Dean moaned, as he was pinned down. Completely at the whim of the alpha above him. He grasps as Cas suddenly flipped him, he went back to nuzzling and suckling Dean’s neck, his tongue scraped across Dean’s gland, sending a shiver down the omega. So close, all he had to do was bite down.
But Cas moved on, his ripped open Dean’s baggy shirt, sucking and nipping down Dean’s back, until he got to his arse. He wasted no time in spreading Dean’s cheeks apart and pushing his tongue into Dean’s arse. He licked around the rim before pushing in, eliciting deep, lustful moans from the omega. After thoroughly eating Dean out, he sat up for a moment, wiped his mouth, looking down at the omega. His omega. He shifted his position on Dean, before lifting up Dean’s arse, forcing him onto all fours. He slammed his cock deep into Dean.
“Hey there little omega. I need you to talk to me, tell me what you need. If you’re in pain. Can you do that for me?”
Dean nodded. “Y- yes alpha. I- I want you deeper. Longer.”
Cas obliged, lengthening his cock as he fuck Dean ruthlessly. Dean moaned loudly as he dropped his head into the pillow of the bed.
“Bigger. W- wider. Fill me up.” Dean begged.
Again Cas obliged, slowly widening and lengthening his cock until he heard Dean’s breath hitch, knowing he was at his limit. And no wonder. Cas was huge in Dean’s arse. Every thrust nudging into Dean’s womb, he sat them both up, allowing Dean to sit in his lap as he bounced himself on Cas’ cock.
Dean felt his stomach, feeling the cock bulge out, stretching his skin. He’d never been filled so throughly with a cock before. He moaned as he bounced on Cas’ cock, arching his back, as he came closer and closer. He slammed down hard on Cas’ cock taking him in fully as he orgasmed. His come spluttering over the bed. Cas came a few moments later, painting Dean’s insides white. He carefully pulled Dean off his enlarged cock and laid his down. He got the toys and pushed it into Dean gaping hole. It was comically small compared to the cock that had just been in. But Cas turned it on anyway. Hot, heavy come flooding Dean with fertile sperm. Cas climbed off the bed, as Dean was filled. First cleaning himself up and dressing before cleaning up Dean.
“Cas.” Dean moaned, as he felt his stomach stretch with the come flooding into him.
“I’m right here. We just need to make sure you’ve got enough in you. Not much longer.” Cas promised.
Dean nodded, moaned as his stomach was stretched with come as he rubbed the hot skin. Finally, Cas switched off the machine and pulled the toy out. Before quickly inserting a large plug, with a wide, flared base.
“Cas.” Dean moaned. “Gonna have your pups.”
Cas smiled as he rubbed Dean’s stomach softly, soothing the skin. “Yes, you are omega.”
After a while Dean slowly sat up, “so do you think it’ll take?” He asked, a playful smile on his lips.
“Oh almost certainly.”
3 months had past and Dean’s womb had certainly taken. He already looked heavily pregnant, his belly button on the verge of popping. Gabriel and himself had taken to building a nest in an empty office room, comfy clothes and bedding that smelt of both Rowena, for Gabriel, and Cas, for Dean. It was unorthodox to have two omegas sharing a nest, but they were practically inseparable.
Dean woke one morning, to Gabriel whining beside him. Gabriel was grunting as he was trying to sit up, his huge pregnant stomach pinning him to the nest. Dean pushed himself to sitting and stroked Gabriel’s hair softly.
“It’s okay, shh. Calm down, Gabby, I can help you up.” Dean cooed.
Gabriel looked up at Dean, well more his own pregnant stomach that Dean’s face but nodded, trusting his new best friend. Dean took one of Gabriel’s hand in his own and placed another on his back, and pulled. Between the two of them, Gabriel managed to sit up, his enormous belly taking up the entirety of his lap.
“Fuck,” Gabriel panted, rubbing his stomach. “I’ve never been so big so early before. I might become more pup than Angel soon.”
Dean smiled softly as Gabriel, still holding him up, scared that the lithe omega couldn’t support his own body. “It’s going to be okay. Ro’ll help and I can do anything you can’t do.” Dean promised.
Gabriel nodded. “Speaking of Ro, can you help me up? I should make plans to become bedridden before it’s forced upon me.”
Dean nodded. Together they stood up, Gabriel swaying slightly before finding his balance. He grunted with every step as they waddled down the corridor to Rowena’s spell room together.
“Oh dearie.” Rowena gasped as soon as they entered her workspace. She dropped the ingredients she was using and quickly moved to Gabriel’s side. She knelt down, rubbing her hands over his stomach, pressing soft kisses to the red, agitated skin. “Gabby, my dearie. Look at you. So full of life and big.”
Gabriel blushed, his cock standing to attention from the praise.
“So big and beautiful. So full of life and gorgeous with it too. However are you standing?”
“With Dean and grace.” Gabriel admitted.
Rowena immediately pulled him up a chair, and with Dean’s help, guided him to sit.
“Dean, dearie, could you go get Cas? We’re going to have to bed rest Gabriel. And it’s going to take all of us.”
Dean nodded and waddled out of the room, search for Cas. His rubbed his stomach, thinking about how big Gabriel had gotten so quickly. In just 3 months from lithe and skinny to bed rest and his stomach bigger than his thighs. Not to mention his breasts. Dean had no idea how Gabriel did it, carrying them all, his breasts heavy with milk. Dean waddled into Cas’ office, still thinking about two mornings prior where Gabriel had practically begged Dean to help drain his over-worked breasts by suckling. It had tasted so rich and creamy.
“Dean? Is everything okay?” Cas asked, bringing him out of his memory.
“Oh, Cas. Yeah, it’s Gabriel, Ro thinks he should be put on bed rest. Can you help us?”
Cas nodded as he followed Dean back down the corridor, his hand resting on Dean’s rotund arse. Claiming him.
“Oh Gabby.” Cas cooed as he saw Gabriel panting just sitting on the chair. “Shall we get you in bed?”
Gabriel nodded. It took three attempts to get Gabriel to stand. Once stood Dean noticed that he already looked bigger. How fast was he growing? Gabriel caught him staring and winked.
“I’m an impatient bastard.”
They decided to head back to the nest, it was closer than the hospital room, and comfier. With each step, Gabriel seemed to grow bigger and bigger. More than once Gabriel’s knees buckled, threatening to give in to the weight. Gabriel stopped for a minute, panting heavily, his fingertips no longer able to reach his belly button. They continued the laboursome walk back to the nest until they reached the doorway. Gabriel grunted as his stomach brushed the doorway, he took another step but didn’t move. He took another one and another one but still he didn’t step through the doorway. He was stuck. He was too big for the doorway. He was truly massive. His knees finally gave way as he slid to the floor. Dean came round to one side of him, Rowena on the other.
“Fuck!” Gabriel cried. “I didn’t want. I don’t want this. I’m too big. I just want my nest.” Tears started to stream down Gabriel’s cheeks. “I’m going to pop. I can’t do it.”
Cas knelt between Gabriel’s legs, gently rubbing his extended abdomen, his skin white under the pressure.
“I can stop this. I can induce you, but I need the pups to grow first. I can’t induce until you’re at time. What do you want me to do?” Cas asked.
“I- yeah- yeah- I can do that. Just get me in the nest.”
Cas nodded, placing both hands on Gabriel’s stomach, and flew them to the nest. Dean blinked for a moment.
Why didn’t they do that before?
He followed Rowena back to the nest, claiming in beside Gabriel, curling around his gigantic frame as he tried to comfort him.
“Dean I need you to suckle. Get rid of the pain for me.”
Dean didn’t need to be told twice, he immediately latched onto one of Gabriel’s breasts. If he had to guess, he’d say Gabriel was a O size, and carrying well over 15 pups. But he knew he was only going to get bigger. He started to suckle, ignoring what Rowena and Cas were doing around him, his only focus was the thick, creamy milk. He switched between Gabriel’s breasts, wanting to drain both of them equally.
Dean moaned as his felt full, and sat back, milk had ran down his chin and onto his own, small abdomen. Gabriel was in the middle of labour. 2 pups were out, but Gabriel’s stomach was still bigger than his head. It looked big enough to live in.
Gabriel’s hand shot up to Dean’s hair and pushed him back down, forcing him to suckle. Dean did so, taking more than his filling. But his friend needed him, clearly.
He sat back again, burping slightly as he looked at Gabriel again. His breasts were much smaller now. Almost back to their normal size, as his stomach, it looked like only one was left in.
Dean watched as Gabriel screamed and pushed out the final pup. He panted heavily, falling unconscious from the sheer exhaustion. Dean looked between Gabriel and Cas, torn between wanting to look after his friend, and knowing what happened to the pups next.
“Rowena can stay with Gabriel, do want to help me with all of these?” Cas motioned to the pups littering the ground, some were wrapped in blankets, some in jumpers, some in t shirts. Anything to swaddle them.
“How many are there?”
“Last count was 20.” Cas explained. “We need to get them to the back entrance, feed them until their new parents arrive.”
Dean nodded. “How…?”
Cas smiled and disappeared for a second, reappear with two large cots on wheels. “They can share.”
Dean nodded as he started to load the pups into the cots. In total there were 24 pups. 24 pups were inside Gabriel, no wonder he looked big enough for a human. He followed Cas down the corridor, pushing 12 of the pups into his cot. They got to what seemed like a load bay. Dean sat beside Cas on a cold, wooden bench. Rubbing his belly.
“You did good.” Cas said softly after phoning around to get people to take them pups.
“Is he going to be okay?” Dean asked, ignoring the compliment.
“He’s stronger than he looks. And Rowena will be there for him, no matter what.” Cas explained softly.
Dean rested his head on Cas’ shoulder, rubbing his milk filled stomach.
“You took in so much milk. You’re looking bigger than this morning.” Cas commented, adding his hand to Dean’s on his stomach.
Cas frowned for a minute, adding his other hand and concentrating.
“What? Are my pups okay?” Dean asked.
“Yeah, it’s not your pups, it’s you. Gabriel’s milk, it had grace in it. This is fascinating. You’re containing Angel grace. If you took on any more you could’ve done some of our magic.” Cas explained. “This changes everything.”
“It does?” Dean asked.
“Yeah. Gabriel and I, we were on Earth when the curse hit. We weren’t suppose to be infected, but we were both low on grace at the time. Thats why I can’t bear children. Thats why Gabriel has a harder time at it than you. He’s burning up his grace just to match you. But if you had grace in you, with your natural ability and the grace on top. You would be strong. Incredibly so. This opens up a world of other possibilities. Gabriel’s grace is stronger of course, being an archangel. And he might not want to give it up. It’s understandable. But…”
Cas continued to theorise and babble about theories, but Dean’s head went elsewhere. Stronger than Gabriel in pregnancy. Maybe he could be as big as Gabriel was. He wasn’t apposed to it. Sure he would be bed bound, but with Gabriel and Cas waiting on his every need he was sure he could do it.
“…what do you think?” Cas asked, bringing Dean back to reality.
“Hmm?”
Cas chuckled, but before he could ask the question again, a car pulled into the loading bay. They both stood, Dean suddenly feeling exposed as he stood there stark naked and covered in another omega’s milk as strangers came. Cas handled most of the discussion, Dean just helped to load 10 of the pups into the van before the human and omega couple left again.
“My question Dean,” Cas continued as if nothing had happened, as they waited for more families. “If Gabriel is willing to uhh… loan some of his grace, would you be willing to try some advanced potions?”
“What advanced potions?” Dean asked.
“We’re having calls from the military, they’re wanting to know if an omega’s womb could… heal a soldier, a man. It would be highly experimental and there’s no way of knowing if it would be a success. The only thing ensuring your safety would be Gabriel’s grace.”
Dean thought for a moment. It was the first thing that Cas had said that actually sounded terrifying. He had seen the pain Gabriel had been in. Did he really want to do that to himself? He laid down on the bench, his head in Cas’ lap, as he continued to rub his stomach, it had become a habit over the past three months to always have at least one hand on it.
6 months later, and Dean was counting down to the birth of his pups. He was absolutely massive. He was in full nesting omega mode, constantly making himself, and everyone else food. 3 months ago he had realised that he could no longer drive. He had gotten into the car that fateful morning to drive into the local town to get fresh vegetables for the meal he was planning to cook for them all. And pushed back his chair as far as it would go to accommodate his new girth but it was wasn’t far enough. The steering wheel digging uncomfortably into his stomach. He had groaned as he pulled himself free, an angry red mark over his belly button.
Now Dean had resigned himself to staying in the clinic, waddling slowly as he made food and cleaned. He was in the kitchen, snacking on spoonfuls of peanut butter as he slowly made the four of them quiche. He kneaded the fresh pastry dough, but when it came to rolling it out he couldn’t reach. His stomach pushed up against the counter top, stopping him from rolling it out fully. He stepped sideways and continued on, rolling out the pastry and putting it in the oven to blind bake. He closed the oven door and tried to stand but couldn’t. He grunted as he tried again but all it resulted in was him loosing his balance and falling onto his pillowed arse.
Cas, Alpha can you hear me? I’m stuck. Dean prayed, knowing the Alpha, his Alpha in all but claim was listening.
A flap of wings altered Dean to Cas’ presence behind him.
“Little omega what are you doing down there?” Cas teased as he stepped into Dean’s view.
“I was making quiche. Please help me.”
Cas smirked and shook his head. “But I quite like the view. In fact I’d like it better if you got on your hands and knees.”
Dean couldn’t disappoint his alpha, he moved onto his hands and knees silently. Well, hands and knees was a stretch. His stomach rested against the cold, stone floor as he pushed his arse as high into the air as he could. He could feel the pups inside him shift and roll, not liking their dad’s new position. But Cas didn’t care about the pups’ comfort. He thrusted into Dean, pummelling his arse fast and hard, gripping Dean’s hips for extra purchase. Cas moaned obscenely as his cock elongated and thickened, fucking into Dean further than any normal cock should.
Dean cried out, as he dropped onto his elbows, his pups now taking most of the weight and they weren’t happy. They kicked and rolled about, twisting Dean’s stomach in odd shapes. He grunted as Cas came deep inside him.
Once Cas had pulled out, Dean rolled onto his side, on the cold kitchen ground. He had to admit that he liked being taken advantage of by his alpha, but maybe not somewhere so cold for his poor pups.
“Please help me up.” Dean begged, as he held his arms up to Cas.
Cas finally obliged, easily lifting Dean to his feet, and holding him steady until he had regained his balance.
“You know,” Dean started. “If you’re really wanting to just take me whenever you want, you should really claim me. Think of it as a constant yes.”
Cas sighed his hands still on Dean’s sides, his thumbs drawing small circles into Dean’s taut skin. “I know. I know as well that if I claimed you, and you were bonded to an angel you’d get strong. You’d be able to use my strength. I just- I don’t know if I can watch you die.” He whispered.
“Could yours and Gabby’s grace not help to you- stop me aging and all that?”
Cas nodded. “Maybe. I’m just scared, I’m sorry.”
Dean pressed a sensitive kiss to Cas’ cheek. “I love you. No matter what you choose, I’ll always been your omega.”
Cas nodded, letting go of Dean, “you should continue cooking. Wanna watch my omega cook for me and my pups.”
Dean chuckled patting his belly as he continued making them all their dinner. He rested his heavy belly on the countertop, feeling Cas’ eyes bore into his fat arse. He didn’t feel as Cas came up behind him, snaking one arm around Dean’s enlarged waist and thrusted into him until it was too late. The sauce he was making, jostled and spilled over his stomach and the countertop.
“Alpha.” Dean protested.
“Keep cooking.” Cas commanded, as he fucked mercilessly into Dean, “don’t come until I say.”
Dean did as he was told, moaning loudly as his pups jostled in his with every thrust. Cas had never been so rough with him before. He was usually gentle, letting Dean take control, but this time Cas took control. His free hand came up, encircling Dean’s neck. Not strangling, but it was enough to make Dean whimper. His cock grew inside the omega, to a size that had it never been before. His tip grazed against Dean’s womb, growing thicker and thicker with every thrust.
“Alpha, I…”
“No talking. You’re going to take my cock. And keep cooking.” Cas ordered.
Dean moaned in response, he quite liked this commanding alpha Cas. One where he didn’t have to think about preferences. Just cook.
The timer went off on the blind baked pastry, and Dean whined, unable to move to get it out. Cas paused for a moment, following Dean down as he reached for the pastry, and helped him back to standing as he continued to cook. Dean bit his cheek, trying everything to stop himself coming as Cas roared and came inside him. But he wasn’t finished. He immediately picked up the pace again. Fucking Dean, until Dean’s cock was rock hard, and angry red from the pressure.
“Please alpha.” Dean begged.
Cas grunted as he came for a second time. The third time wasn’t far behind.
“Come.” Cas ordered on his fourth orgasm.
Dean came on the next stroke in. His pitiful come, spattering against the countertop and his belly.
Cas allowed Dean to move again, putting the quiche back in the oven. But as soon as Dean closed the oven door, Cas twirled him again, laying him against the kitchen table as he fucked him again and again.
“You’re in rut.” Dean whined as his pregnancy-addled and throughly fucked brain finally worked out what was happening.
Cas grunted. Words were getting harder for Cas to form. Even when the timer went off, Cas didn’t let up. Sure, he allowed Dean to serve them both up a slice of the quiche, but as soon as the food was on plates and on the table, he got back to fucking his mate. It took some manoeuvring but they managed to seat Dean in Cas’ lap, his huge belly squashed between them.
Dean happily took up the mantle of fucking, bouncing on his alpha’s cock as Cas picked up the quiche, feeding Dean.
All Dean had to do was bounce, open his mouth, chew, swallow, and repeat. It was simple. His mind glazing over, enjoying the feeling and nothing else. He didn’t even realise when Cas had fed him the entire quiche, apart from his belly feeling slightly more taut, and the pups languishingly rolling. He also didn’t hear the chair creaked more and more under each bounce, until the chair broke.
Cas fell back, Dean dropping heavily on top of him, his belly covering most of Cas’ stomach and chest, and completely bottoming out. Dean cried out as the cock pushed against his womb, breaking his waters.
“Cas. Cas. Please. They’re coming. Labour.” Dean begged, not sure how much Cas would understand in his rut-filled mind.
And he didn’t, his continued to buck his hips, trying to fuck his enormous omega above him. Dean cried out, his stomach pinning him to his rutting alpha.
Gabriel. Gabby. Can you hear me. Please hear me. Get Rowena. I need… I’m in the kitchen. I’m in labour. Please. Cas’ in rut.
Dean cried out as a contraction rippled through him, the first pup trying to move down his birth canal but a huge cock blocking it.
Gabriel and Rowena came within seconds. Within seconds they had lifted Dean off Cas, laying him on his back. Gabriel flew them to their nest as Rowena held back Cas, putting a spell on him to let him sleep.
Dean lay in his and Gabriel’s nest, his legs wide open as he bore down through his contractions. With how wide Cas’ cock had made him, the labour really wasn’t that difficult. But they did brush against his prostate just right.
“Gabriel. Come here.” Dean smiled, pulling Gabriel closer. “Want your milk.”
“Anything Dean-o” Gabriel moved to lay beside Dean, helping Dean to latch on.
They moaned together, Gabriel being emptied and Dean pushing out his pups. 7 pups and 3 orgasms later Dean’s belly was empty once more, sans Gabriel’s grace-filled milk. Gabriel gently pulled away, starting to clean up and swaddle the pups.
“Cas offered me something.” Dean said as a while.
“Hmm?”
“He said that your milk is giving me grace myself. That between my natural ability to birth and the grace he and Ro could do some more… dangerous experiments.” Dean explained. “He said that my womb could have… healing qualities for military personnel.”
“Like unbirth?” Gabriel asked.
“Yeah I think. I just… I’m scared, but-“
“But you’re turned on at the idea and not just because you’d make your alpha happy?”
“Yeah.”
