dog!dean breeding sam hoping to knock him up with incest puppies 🥰🥰
As promised here is part two to this ask
--__--__--
Sam had worried that the rest of the day would be incredibly awkward after Dean’s knot had finally deflated, letting him get up and go let the Colonel back in.
Dean had argued with the dog for a little while but Sam had tried to ignore it while he went to take a shower and to get rid of the cum that was still drying on his skin and leaking out of him.
The rest of the day and most of the night flew by with them finding and confronting the killer and then having to clean up the scene to make it look as non-supernatural as possible.
It was time to go back home but there was one thing they still needed to do in Enid.
“So,” Sam started. “What are we gonna do with the Colonel then?”
“I don’t know,” Dean answered, stopping his packing to look at the dog that was laying on the carpet.
“I bet those guys from the coffee shop would adopt him,” Sam offered.
Dean scoffed. “And force him to eat vegan shit for the rest of his life? Sam, that’s inhumane.”
“You got a better idea?”
Big puppy eyes were on him. “We could keep him?” “No we can’t. We’re on the road most of the time and the bunker doesn’t exactly have a backyard,” Sam argued, staring at Dean.
Instead of replying to him, Dean turned to the dog, having a clipped conversation with him and leaving Sam just standing there.
“He’d be fine with it,” Dean said a few moments later. “He’s pretty self sufficient, Sammy.”
Sam only stared at Dean harder, not believing what he was hearing. “You do know that the spell is gonna wear off and you’re not going to be able to understand him, right?”
Dean scrunched his brows for a moment but nodded.
Sam sighed, not really willing to argue with Dean and a dog when he knew by the look in Dean’s eyes that he would lose anyway. “A week Dean to see, and otherwise we’ll give him to somebody else, maybe Garth would want a dog.”
Both Dean and the dog grumbled for a second but then Dean turned and continued to pack his bag.
..
Kevin hadn’t mentioned a specific time frame but Sam would have guessed twenty four to forty eight hours for the spell to wear off. Forty eight had passed while they were in the car driving back to the bunker and yet Dean was still behaving like a dog, barking at other cars and making Sam drive the whole way.
Five hours later and Sam was very glad when he finally pulled into the bunker’s garage, glad to be out of the car with his weird dog companions.
Usually they did their own thing for at least a couple of hours after a hunt so Sam wasn’t surprised when Dean and the Colonel disappeared after getting back. Sam took the opportunity to start a load of laundry that was desperately needed.
Not even half an hour later though Dean came back and sat next to Sam in the library. Next to him and not across like he usually did. Sam raised an eyebrow and looked at Dean in question.
“What?” Dean asked.
“What are you doing?” Sam asked back, gesturing from where Dean was sitting to his usual seat.
“Nothing dude, just checking on you.”
And that only confused Sam even more, well, it actually kinda pissed him off. He was feeling fine and he didn’t have any lingering aches or anything from the Trials. Why couldn’t Dean just get that.
“I’m fine,” Sam ground out and turned back to his laptop where he had begun to archive the hunt they had just come back from.
“I’m just checking,” Dean defended himself but didn’t make a move to get up or leave after Sam had reassured him that he was fine.
Sam tried to ignore Dean and focus on his task and when he looked up a few minutes later his brother had scooted closer to him, almost sitting in his lap.
“Dean?”
His brother looked up from his phone where he was playing a game.
“You ever heard of personal space?” Sam asked.
“God forbid, if I missed my brother,” Dean replied with a put upon tone.
“What? That doesn’t even make sense. We literally spent the last two days together.” Dean just rolled his eyes, got up and left but not without running his hand along Sam’s shoulder slowly, his fingers dragging over the bite mark that was still smarting when touched.
Sam watched his brother go, feeling confused and irritated.
..
An hour later Dean sidled up to him again, chest pressed to Sam’s back as he was switching the laundry from the washing machine to the dryer.
Sam sighed before speaking. “Dean,” Sam complained at the way his movements were now restricted.
“I think it’s the spell,” Dean said, moving even closer as he pressed his face into Sam’s neck. He sniffed and licked at Sam’s neck, pushing his hair to the side to get better access.
“God, you smell so good, Sammy.” Dean’s voice was muffled and Sam felt the vibrations against his skin, goosebumps breaking out.
“I don’t- c’mon, Dean, let go,” Sam said, letting the laundry go as he tried to pry Dean’s hands off of him.
Instead of letting him go though, Dean held him tighter and Sam could feel his brother’s obvious bulge rub against his ass.
“Please, Sammy, c’mon,” Dean mumbled, his hips pushing against Sam’s ass again and again.
“Dean the spell will wear off you just gotta wait-”
“I can’t wait.” Dean nipped at the bite mark he had left, his hands going to the front of Sam’s pants as he did his best to open them blindly.
Sam grabbed Dean’s hand and tried to pry it away but Dean growled, fingers squeezing Sam’s wrist and Sam flinched. Dean was behaving like an aggressive dog and if there was a mirror he would probably see his teeth bared.
Dean let his wrist go when Sam whimpered quietly at the pain in his wrist, licking at his bite mark again. His brother’s hand went back to his pants, the button already undone and the zipper being pulled down.
Sam thought about stopping Dean again but there was no way Dean wouldn’t snap at him, wanting to be the leader of the pack or whatever else doggy thing his brain was cooking up.
“Not here,” Sam pleaded instead. “A bed, Dean, c’mon.”
Dean grumbled and groused for a moment but apparently agreed with Sam’s request. He straightened up, hands gripping Sam’s waist as he maneuvered him around and out of the room.
Unsurprisingly it was Dean’s room where they ended up, the door was already open and Sam could see the Colonel get up from Dean’s bed. The dog squeezed past them and Dean shouted after him to mind his own business before he slammed the door shut behind them.
“Strip,” Dean growled and Sam felt a shiver run down his back at the sound, the animalistic undertone that made Sam comply in worry of something he didn’t want to think about.
Dean was already naked by the time Sam was about to push his boxers down and apparently his brother was impatient because he took over, pulling the fabric down harshly and Sam could hear at least some of the seams rip.
Sam hit the bed with an impact, bouncing slightly on the memory foam. He felt a sense of deja-vu when Dean once more parted his cheeks to bury his face between, immediately latching onto the sensitive rim. Dean took his time, licking and sucking and biting at his flesh, his stubble burning Sam’s cheeks.
“Need to fill you up again, Sammy, you don’t smell like me anymore,” Dean mumbled after lifting up just a bit and Sam had to force down a slightly hysterical laugh at not just the absurd situation but also knowing there was no way he could argue with Dean or stop him.
Dean dove back in, his tongue lapping at his hole, getting it sloppy wet. Sam was glad there was enough human left in Dean that his brother knew he needed to prep Sam properly, that he wasn’t a dog that could just be mounted. Though it still didn’t feel like enough when Dean did end up essentially mounting him. Dean’s dick breached him after only two fingers and a bit of lube. Sam tensed up, biting down on the pillow to muffle his sounds, knowing they wouldn’t benefit him anyway and he didn’t want to distress Dean unnecessarily.
Sam was stuck under his brother once more, his dick driving in and out of him relentlessly. “Please, Dean,” he pleaded, what for he wasn’t even sure.
Dean growled, nipping at his neck in response but one of his hands snaked underneath him and gripped his dick. It wasn’t exactly what Sam had wanted but would take it nonetheless.
Sam moaned which only encouraged Dean, hips driving in faster and he actually grazed Sam’s prostate. He must’ve made some kind of noise because Dean licked at the bite mark and replied with a happy huffy sound.
“Taking it so good, Sammy,” Dean said breathlessly. “Smell like mine, ready to breed.”
Sam wanted to argue but the feel of Dean’s hand on his dick and his cock rocking against his prostate made it difficult to focus on anything but that.
“Gonna fill you up good. You gonna be a good boy and give me all the puppies, right?”
Sam moaned, not in consent but Dean didn’t care, only babbling on about how he would breed Sam up and how Sam would be so perfect all round with his litter.
The pleasure and absurdity of it all must’ve gotten to his head because he was feeling almost lightheaded and pliant, not able to say anything or stop his brother.
Dean was pounding into him, the pleasure almost cresting and he knew he wouldn’t last much longer.
His brother’s thrusts got sloppier and Sam could feel the way his rim had to stretch around the growing knot, the pressure growing almost painful until Dean pushed in one last time. His knot inflated all the way, locking them together and it was enough to bring Sam to orgasm.
“Yes, Sammy, come on my knot, c’mon,” Dean encouraged him, hips still rocking slightly as he filled Sam up, pulsing deep inside him. “Milking me so good, gonna get you all filled up with my litter.”
Sam’s face was pressed down into the pillows as Dean bit at his neck again, not enough to break the skin but enough to keep him in place while he still came inside Sam, his knot plugging him up.
Sam felt so full, muscles clenching around Dean’s knot, his own orgasm long gone when Dean finally turned them onto their sides, tongue and teeth still working on his neck.
The knot pulled uncomfortably as Dean rearranged them, his hand coming up to their faces and Sam made a disgusted face at the thought of Dean wanting him to lick his hand but instead Dean himself licked it clean. Moaning as he cleaned Sam’s cum from his fingers like he had gotten messy from eating a piece of pie or something. It was disgusting but Sam’s dick still twitched at the sight, a groan deep in his throat.
“So good, Sammy,” Dean groaned afterwards, his now clean hand pulling Sam closer. It was laid on Sam’s stomach, stroking the skin where Dean had filled him up. “Perfect bitch for me, Sammy, took me so well, let me breed so up so good.”
Sam couldn’t hold back the hysterical laugh now, doubting if this was actually reality for the first time in two years ever since Lucifer had left him. Maybe this wasn’t actually real or maybe his brother had actually grown a knot and fucked him in the belief of getting him pregnant with puppies.
He didn’t know which was worse, all he knew was that he could do nothing about it with being stuck on Dean’s knot so he closed his eyes and succumbed to sleep.
