Chapter Text
The only way that Dean could describe returning to the bunker was slunk. He slunk in, tail between his legs,hoping to avoid Sam or Cas’ attention. All he wanted was to retreat to his man cave and try to forget that any of this had ever happened. Unfortunately, Sam and Cas were seated at the map table and Dean was unable to avoid Cas’ sharp eyes.
“Hello, Dean.” Cas said with a small smile in greeting.
“How'd it go?” Sam looked up from the glow of his laptop.
“Fine,” Dean said tersely. He hung in the doorway, wondering whether he should give in to getting comfort from Sam or if he wanted to just hide.
Sam narrowed his eyes, gaze shifting over him. “What's wrong?”
Nope, scratch that. Don’t want to talk about it. “Nothin’. Exam checked out and the place was clean as a fucking girl scout meeting.”
That fucker kept staring at him. “They take your blood?”
“Yup,” Dean replied.
Sam leaned back and crossed his arms. “What else happened, Dean?”
Dean looked towards Cas almost as if for help. The angel had a little furrow between his brows. He looked back to Sam who’s expression said that he was not going to give this up. “What's with the twenty questions?”
“Just wanna know how it went. Was the doctor...thorough?” Sam wasn't quite showing his hand but the shadow of a smirk tugged at the corner of his mouth as he leaned his chair onto its back legs. He was fucking up to something.
“If you’re asking if he felt me up, yeah, I was felt up,” Dean snapped.
“Isn’t this man supposed to be a professional?” Cas looked alarmed.
“It's a normal part of a health exam, Cas. Especially at Dean’s age.” Sam’s dumb smirk was now on full force.
“Why are you looking at me like that, Sam,” Dean asked, “you get some kind of twisted happiness about some random silver fox with his hand up my ass?”
“Silver fox, huh? So you liked him?”
Dean sighed, rubbing the back of his neck and shifting a little in embarrassment. “Yeah, okay so he was good looking, so what?” he asked Sam defiantly.
Cas looked between the brothers, bemused as Sam was deciding to act like a dog with a bone. “So, uh, did it hurt?”
“No it didn’t hurt, you know that Sam!” He shifted a little more. “You done? Can I go shower now, or you gonna keep fucking badgering me?”
“Why you getting so butt-hurt? Pun not intended,” Sam teased with a little shit grin.
“Because these are… very… personal questions, Sam.” Dean replied, squirming a little.
“Sam is your brother and your lover, Dean,” Cas pointed out.
“SO?!”
“So, if you would tell anyone it would be him. Are you upset? I could teach him a lesson-”
“No, Cas, I’m good just… tone it down there a bit alright?”
Sam snickered, he actually fucking snickered. “I’m just curious...it’s your first, uh...exploration of the area, I’m surprised it didn’t hurt…I figured you’d be bitching and moaning.”
Dean shifted uneasily from one foot to the other. “What are you trying to get at, huh?”
Sam shrugged maddeningly. “Well, since you aren’t complaining, it makes me wonder.”
“I came okay!? Happy? He did a fucking prostate exam and I jizzed all over the goddamn exam table,” Dean barked, throwing his arms up.
“Whoa, what!” All four of Sam’s chair legs slammed to the floor. “Y-you, what !” He gaped at him with a stupid, surprised expression.
“Yeah, yeah laugh it up, chuckles,” Dean said, rolling his eyes. “You done?”
“Dean, honestly, I just thought you might like it, I didn’t think you’d...you’d…” He was eyeing him now, smile becoming smaller but eyes still round.
“Come on, let's hear it,” Dean said, snapping his fingers. “Just get it all out there. Get it over with.”
“Nothing.” Oh, now he wanted to clam up. “It’s nothing. Sorry it was a, uh...bad experience for you.”
“It’s just...whatever. Just drop it ok?” Dean paced, rubbing the back of his neck. Sam said nothing, he just eyed him shiftily. Dean could practically see the wheels turning in his little brother's head.
***
Dean looked up when his brother entered their shared bedroom. He had thought about slinking off to his old room but he knew that Sam would accuse him of being ‘passive aggressive,’ something Dean had been working on since they stopped being just brothers and fuck buddies. Dean still felt it strange to say that they were dating. It still made him feel like a schoolgirl to call Sam his boyfriend, but it made Sam happy and Dean wasn’t afraid to admit that he had spent most of his life trying to make Sam happy.
Still, despite the fact that he was being pointedly not passive aggressive, he wore headphones and was listening to The Wall so loud, he was sure that Sam could hear the tinny sound from where he stood in the doorway.
Sam sat on the edge of the bed and gestured for him to take the headphones off.
Dean stared back a moment, gauging how much of an asshole he felt like being before taking the headphones off. He rubbed his eyes with the heels of his palms. “Yeah, Sammy?”
“Listen, I was just teasing, I didn't think you were that embarrassed.”
Dean huffed. “I wasn’t embarrassed.” Lie. “You were pissing me off, beating a dead horse like a bitch.”
“Ok sure, Dean,” Sam smirked. “Either way, it's not a big deal that you liked...yah know...that.”
“I guess I’m just kinda…” Dean trailed off. One of the ‘rules’ Sam had made when they started this whole boyfriend thing was to be better at communication. But Dean is to communication as oil is to water. “It’s just…why’d it have to be the doc?”
Sam looked like he was actively fighting a smile. “Well, it coulda been me, but you made it pretty clear early on it was a no go for you.”
“Easy, I can practically smell the I told you so.”
“And, yah know, if you liked it there’s no reason we can’t...play...with it.”
Dean narrowed his eyes at his brother a little. “Try not to look so damn smug. You look like fucking Tim Curry.”
Sam rolled his eyes. “Do you ever watch or listen to any content released after 1995?”
“Shut it. ‘Home Alone 2’ is a classic,” Dean said. He eyed his brother. “You seem really into the whole idea.”
Sam shrugged. Dean knew him well enough to see that he was feigning nonchalance. “I mean...could be interesting.”
“Interesting? That's the face you make when you want to but you don’t want to make a big deal about it because you don’t want to scare me off. It's the same face you made that time you said that balsamic vinaigrette is an okay flavour. Which, by the way, it is not.”
That earned him a bitch face. “Fine forget it, stubborn jerk.”
***
And Sam did ‘forget it,’ for a while anyway. Long enough that Dean had blissfully assumed that it wouldn’t come up again. He had never been so wrong.
Sam was above him, their chests flush. Dean always felt a little safer with his brother’s weight on him. Sam had their cocks slick together in one of his big hands as he kissed Dean like he wanted to steal the breath from his lungs.
Dean’s arms were snug around Sam’s strong shoulders, holding him close in his space. His hips rolled up into Sam’s hand in small aborted thrusts and, God, did Sam’s dick feel good next to his. Fat and wet and just- there was something about how taboo it was to be so obsessed with his brother’s cock. It just made it even hotter somehow even after all this time.
Sam shifted a little and Dean barely noticed until he felt two slick fingers rub against his hole. He froze, anxiety pulsing through his chest. He pulled back from their kisses to look up at Sam with alarm. “What are you doing?” His voice cracked in a very undignified way that Dean absolutely did not want to dwell on. Not with Sam’s huge fucking fingers all up in his taint.
Sam, completely undeterred, just put a little bit of pressure against Dean’s hole and bent to nibble along Dean’s neck, the little shit. Dean had always been sensitive there and Sam fucking knew it. “Let me,” he murmured, and that was definitely Sam’s bedroom voice. The tone he got when he was turned on passed reason. “Please Dean, I can make it feel so good for you.”
Dean groaned and not in the sexy way. More in the ‘I’m straight up done with my little brother’s shit’ sort of way. “No Sam. It's not-”
“Not manly?” Sam asked, looking Dean in the eye. “Do you think it makes you less than somehow? Does that make me less than since I take your dick?”
“No, Sam, that's not-”
“Then what's the problem?”
Dean knew in that moment that Sam had won. And by the small smirk playing on Sam’s lips, He knew that Sam knew that Sam had won. Dean huffed a little, rolling his eyes. “Fine…”
Sam smiled then and it damn near blew the wind out of Dean’s sails. It was the same smile that Sam used to wear when Dean would let him have the last bowl of their favourite cereal. The look Sam would get when Dean let him drive the impala on rare occasions. Dean knew then that he was doomed at the sight of that smile because he’d always do anything in his power just for a glimpse at that damn look.
Dean had no idea how the sneaky shit had managed to get more lube on his other hand but Sam’s index finger was wet as it slid into Dean’s ass. It was uncomfortable at best, absolutely nothing to phone home about.
Sam bent to kiss the furrow in Dean’s brow and then his mouth. “Relax, Dean. I got you.”
Dean let out the breath he had been holding and tried to relax for Sam. He stared up at him until Sam had found that spot deep inside and pressed it, making Dean see stars. His back arched, mouth falling open in pleasure.
“There we go,” Sam purred. He let Dean adjust a little before he started fucking his finger into him. Things were starting to feel a bit better. Looser and that's when Sam pressed the tip of finger number two against his rim.
“Wha-” Dean’s question was cut off as Sam pressed his prostate again, making him keen. “ Fuuuck, Sammy.” And the second finger was inside of him. It burned a little but the feeling was there with something else now. A stretch that Dean usually associated with the bathroom but now it was from…well it was pretty ok.
And then Sam was scissoring his fingers and Dean realized that Sam was getting him prepared for something more than fingers. For a moment, Dean was too shocked at this to really think about much else.
“There you go, Dean. Nice and easy. How does that feel?” Sam was talking to Dean like he was a goddamned spooked horse. How did he feel? He took a moment to really consider his body and the sensations Sam was giving him. He realized then that he was actively fucking himself down on Sam’s fingers.
“Fuck.”
Sam’s sweet smile turned into a smirk that was far more sexy than it had any business being. “What was that, Dean?”
Sam hit his prostate again and the feeling of it had Dean keening and rolling his hips more actively. He was genuinely fucking himself onto Sam’s fingers now. “More, Sam.”
“You know, It would be easier for you if you were on your knees.” Of course Sam would say that. It's what Dean had told Sam the first time he had fucked him, almost verbatim. It was all kinds of hot and embarrassing to hear the words come back to him. With a grumble, He moved so he could get his knees under him.
Sam soothed a mammoth hand up Dean’s back so it could spread across his shoulder blades. He pushed down there so that Dean’s chest fell to the bed, ass canting up and on display for his brother. The position made Dean’s neck feel hot but before he could snipe or complain, two of Sam’s long fingers returned to Dean’s ass, touching his prostate.
Dean’s moan sounded far away, as if it didn’t come from himself and he pressed down on the bed so he could buck his hips up and back into Sam’s fingers. “Do it.”
Sam’s free hand was back, soothing along one of Dean’s ass cheeks this time. “Easy…use your words, Dean. What do you want?”
“Fuck Sam, I want more! Don’t make me fucking say it.”
Sam snorted. “I’m not giving you anything unless you ask for it nicely.” His voice held the same stubborn tone that it did when he used to mouth back to their Dad- No… No, Dean did not want to think about that right now. Nope that was a boner killer right there.
“You’re such a smug little-”
The fingers of Sam’s free hand tapped his ass. “Be nice, Dean.”
Dean huffed. “Gimmenotherfngr” He mumbled into the bed.
“What was that?”
“FUCK! Sam, Can I have another fucking finger ?” Dean growled.
Sam finally complied, pressing another finger inside and went straight to Dean’s prostate. The stretch was good now. It made him want more, more, more. He wanted to feel full of Sam. Wanted Sam to crawl inside him and make a home there. There had always been room inside Dean for Sam and now that Sam was physically inside of him he was feeling a little drunk on it.
Sam’s fingers hadn’t left his prostate. They lingered there, pressing and fluttering as if they were fingering a clitoris and not buried deep in Dean’s ass. His orgasam came out of nowhere and crashed over him like a cresting wave. Dean might have cried out. He wasn’t sure. Couldn’t remember because when he came down, Sam’s fingers were still pressed up against his prostate. One hand splayed low and possessive on Dean’s belly.
“Jesus Dean-” Sam breathed, his tone filled with something like awe. “That was so fucking hot. You came for me without me even touching your cock.”
Dean tried to speak but his brain wasn’t connected to his mouth any more and all he could manage was a muffled “Hnnnnggg”
The fingers in Dean’s ass withdrew and two fingers hooked on the rim, pulling in either direction. “Your hole looks so fucking cute like this.” Sam continued.
“Tha fuck?” Dean slurred.
“So good for me Dean. You’re taking my fingers so well. You came so pretty for me.”
Sam was normally a bit chatty during sex and before, Dean didn’t think much of it. Now though it had him squirming as the praise sank into him like a balm. It made him want to keep being ‘good’ so he could get more.
He was such a fucking addict.
Sam’s fingers pressed inside again, honing in on his prostate again and Dean whined; a thin pathetic sound. “Saaammmm.”
“Yeah, Dean?”
Dean shuddered as Sam’s calloused pads roughed over the bundle of nerves. “That's sensitive.”
“I know.” Sam nearly purred, clearly pleased with himself. “I wanna see how much you can take. Wanna see you needy and trembling.”
Dean felt a fourth finger then, pressing against him. “Fuck- yeah, give it to me Sam.” He wanted to see how much he could take too. Wanted to take whatever Sam would give him. He wanted-
“Fuck me, Sammy.”
Sam’s breath hitched audibly. “Say it again.”
“F-fuck me.” Dean growled a little.
Sam hummed, keeping his fingers snug up against Dean’s prostate. He leaned in a little to let his fingers slide down Dean’s mostly soft cock. It valiantly twitched in his hand, trying to fill again like a good little soldier. Sam pressed the tip of his index finger down on the head of Dean’s cock. Slid along the slit.
“There are sounds that go so deep that I can massage your prostate through your cock. I could make you come like that so hard that you forget your name.”
Dean whined. Not because that sounded like a fun time but because how did Sam know how to do that? What kinky shit did he get up to in that fancy college of his? Sam was humming again though, sliding his hand back down Dean’s cock. Its attempts at getting hard had flagged at the idea of sounding.
“Looks like you don’t like that idea so much.” Sam commented and closed his thumb and forefinger around Dean’s cock. He started to stroke him. It hurt so good. Dean was ready to crawl out of his skin with the overstimulation of it all. Then Sam’s fingers pressed into his ass again, honing in on his prostate like a goddamn bloodhound on a scent.
Dean’s body tensed and his head fell back on Sam’s shoulder with a moan as his body bucked against his. He was shivering and the sudden coldness on his cock told him that he was wet again. Sam kissed his spine.
“Look at that Dean. you’re just dripping for me. Like a steady stream of milk just for me. You’re so good for me Dean, taking what I give you. I think you deserve a reward.” Sam sounded as wrecked as Dean felt. Dean hoped that meant that Sam was going to give in and fuck him finally.
Dean tried to speak but his mouth had apparently stopped working again. “Please-needyer-fucknnggghh” He managed.
Sam removed his fingers. His hand slid off Dean’s cock to his hip. “Put your hands on your ass. Hold yourself open for me.” Dean fumbled, trying with trembling fingers. “That's it. Such a good Boy, Dean.” The blunt head of Sam’s cock pressed against Dean’s ass.”
“Oh fuck yes, please!” Dean cried out. He’d buck against Sam, trying to take him in but he was trapped in the pose, pulling his ass cheeks apart for Sam.
“Tell me what you want Dean. What will your reward be?”
“Fuck meeeeeee-” Dean wailed and Sam slammed into him so hard he saw stars. He had to let go of his ass and drop his hands forward to keep himself balanced with the force of it. “Oh-fuck-”
Sam was still then, fingers sliding down Dean’s spine, stroking him as Dean desperately tried to adjust to Sam’s cock. It was thick and heavy and long. Dean was sure the damn thing was hitting his stomach at the moment. How he managed to fit into Jess he’d never know.
He could feel his hole fluttering and flexing against Sam’s cock, trying to adjust. Sam’s big hands came down to massage the globes of Dean’s ass. “Tell me when you’re ready-”
“I’m ready.”
“Yeah?”
“Fucking Hell Sam. Give it to me.”
Sam’s chest lined up against Dean’s back then, engulfing him. He pressed into Dean making Dean feel entirely trapped, consumed. Sam’s mouth came to the shell of Dean’s ear and nipped on his ear lobe. Dean’s cock throbbed as the sting in his ass subsided.
“Anything for my good boy.” Sam rasped before pulling back. The hot line of Sam’s chest vanished and so did his cock before it slammed into Dean again. Over and over Sam drilled into Dean. Every thrust pushed Dean up the bed until he had to put his hands out on the head board to keep himself from hitting his head every time Sam fucked into him.
He gripped Dean’s hips so hard, Dean was sure it would leave bruises and that turned him on more than he could fathom. Everything about this, he felt well and duly owned.
Everything was narrowed down to Sam. His hands and cock and body. His breath coming out in wet puffs as he chased his orgasam. And that’s what he was doing. He was fucking Dean with a single mindedness that made Dean feel like he was just being used to get off. The very thought of that was beyond what Dean could handle and he was coming untouched again.
“Holy shit, Dean. Coming on my goddamn cock again. So good, big brother. Such a good little cock slut for me.”
“Fuuuck Sam, that’s-”
His words were cut off as Sam’s fingers dug into his skin impossibly harder. He pulled Dean back onto his cock with every thrust now and it was all Dean could do but hold on. One arm snaked around Dean’s waist and he was hauled up so his back was flush to Sam’s chest. In this new angle, Sam thrust up into him once, twice and he was coming, biting down on Dean’s shoulder with a groan.
“Fuck, Sammy!”
As Sam started to come down from his orgasm, he pet Dean’s chest. “Dean, fuck, I cant- I can’t believe you let me have this.” Sam tilted his forehead on Dean’s shoulder.
“You made a very compelling argument, man,” Dean panted, grinning, “and you’re stubborn as fuck.”
Sam huffed a laugh. “So whatcha think? Into it?” He asked, pulling his cock free, making Dean keen, one last wave of pleasure chasing through him. The little shit definitely did that on purpose.
“Just shut up and move so I can get off the wet spot.” Dean said, smirking. He couldn’t let him win that easily; where’s the fun in that.
