Chapter Text
When Sam turned sixteen, he went batshit fucking crazy.
Or at least that was how Dean liked to describe his little brother’s sudden transformation into a rude, rebellious asshole. It was like one day the kid just woke up and BAM; he was a giant ball of teenage angst, sporting quite the authority issue.
Of course, at first, Dean didn’t think much of Sam’s new, loathsome, disposition on life. Especially when Sam was directing most of his ‘fuck the man’ attitude toward their father, but still listening to his big brother. However, when Sam decided to start disobeying Dean as well, he took personal offense. Seriously. It pissed him the fuck off when Sam defied his direct orders because he knew, Sam fucking knew that Dean was only trying to look out for him. It wasn’t an authority trip, or even a ‘ha ha I’m your big brother so you have to do what I say’ sort of thing. He was twenty years old, practically raising a teenager on his own because their dad was always off on one hunt or another, and the only thing he’d ever wanted to do was to keep Sam happy and safe. Yet, his little brother was walking around with a chip on his shoulder, talking back, and staying out way past curfew causing Dean to constantly worry. The ungrateful little brat. How dare he pull that shit with Dean? Hell, Dean was far more lenient than their father, but still, Sam tormented them equally. It was infuriating.
And on top of his shitty attitude, Sam began wearing that lame ass punk-rock attire that Dean had loathed to see when he was still in high school. Not to mention, he’d dyed his ridiculously long, shaggy hair black. He’d also started to hangout with a group of little punks, not one of them with a brain in their head, who were constantly getting Sam into a shit ton of trouble at school; and he’d even had the balls to, quite illegally, get his tongue and lip pierced without John or Dean’s consent.
Not that Dean didn’t sympathize with Sam on an emotional level, cause he did. It wasn’t too far in the past that Dean himself had been a pissed off, hormonal teenager, and he really did get it. Which was why Dean tried his damnedest to keep his arguments with Sam to a minimum, and he did his best to give his little brother a healthy amount of space. For months, Dean overlooked Sam’s hurtful, not to mention extremely problematic, behavior, all the while taking pity on the angsty little bastard because he knew Sam was hurting, and he hated that his little brother wouldn’t, or possibly couldn’t, tell him why.
Well, at least that was until one random Friday night in the middle of September, when Sam didn’t stumble back into their motel room until three o’clock in the morning, and Dean just lost it. Honestly, he’s seen the confrontation coming from a mile away; Dean was just surprised that Sam’s lack of time management happened to be the straw that broke the camel’s back.
“Seriously, kid? Do you have any idea how worried I’ve been?!” Dean asked in a furious tone, barely letting Sam shut the door behind him before he was in the younger boy’s face. Temper flaring even more when the salty, bittersweet smell of sex and weed reached his nose, noticing that Sam’s eyes were hooded and glazed over; his little brother looking completely boneless and high as a fucking kite.
“Chill, dude,” Sam giggled as he smiled widely at Dean, hands finding their way to his big brother’s pajama covered hips. “I was just havin’ a little fun.”
“And you couldn’t bother to call or text to let me know you’d be out so late?! What if you’d been hurt Sam? I had no idea where you were. You coulda been face down in a ditch somewhere and I woulda never known!”
A slow, mellow smile spread across Sam’s lips at that, the younger boy taking a wobbly step forward so that his body was pressed firmly against Dean’s. He leaned in, looking Dean straight in the eyes, gaze full of wonder and amusement; the smell of sweat and smoke on Sam’s skin, thick and heavy, causing Dean’s nostrils to flare, a strange, white hot sensation streaking across the older boy’s abdomen when he felt Sam’s breath, hot and ragged, over his mouth.
“That’s seriously baffling to me, De,” Sam said thoughtfully, face far too close to Dean’s for comfort.
“Wh-what is?”
“You sounded and acted more like a father in the last minute than John has in my entire life.”
“Damn it, Sam. Don’t start with this crap. Dad keeps us safe, and you know that,” Dean huffed, eyes narrowing at the feeling of Sam’s fingertips gliding up his bare sides, goosebumps forming in their wake.
“Sure,” Sam agreed without hesitation, startling Dean by inching a little closer so that their foreheads were touching.
Of course, Dean’s first instinct was to pull away and put at least two feet between them, to make Sam stop pawing him for just a damn minute so he could get his head on straight. Unfortunately, however, he was forced to stay still, knowing all too well that his support was the only thing keeping his obliterated little brother upright at the moment.
“He does keep us safe, but he’s not a good father. Hell, he’s not even a decent father, and I can prove it. He never used to tuck me into bed when I was a kid, you did that. He didn’t sing me back to sleep in the middle of the night when I woke up in tears because I had a terrible dream, you did. He didn’t teach me about sports, music, or girls, you did. He didn’t teach me what it means to be a good man, De, you did. Shit. He didn’t even teach me how to drive. That was all you.”
Swallowing hard, Dean reached up with both of his hands, which, much to his dismay, were trembling, and grabbed Sam by the shoulders, forcing him to step back.
“S’not a big deal, Sammy. That’s my job, y’know, to take care of my pain in the ass little brother.”
Dean’s tone and facial expression suggested that he was kidding, even though he absolutely wasn’t; either way, he knew Sam could see right through his bullshit. And for some reason beyond Dean’s comprehension, Sam took offense to his statement, shoving Dean hard in the chest before staggering forward a little, the older boy recovering just in time to steady him before he fell.
“Why do you always defend that worthless piece of shit?!” Sam yelled, smacking Dean’s hand away.
“I’m not having this argument again, Sam. Just shut up and go to bed.”
Letting out an indignant huff, Sam angrily shrugged off his jacket, letting it fall to the floor before he stomped, or rather stumbled, over to his bed. He toed off his shoes, nearly falling on his face when he bent down to remove his socks, but recovered, with the grace of a fish out of water, to pull off his t-shirt, tossing it to the floor as well.
“Really, dude? You’re just gonna leave your dirty clothes strewn all over the place?” Dean asked pettily as he kicked Sam’s jacket across the smooth hardwood floor.
“Get bent, fuckface,” Sam retorted, throwing Dean a dirty look over his shoulder as he shimmied out of his jeans.
“Y’know, you’d think for a dude who just got laid that you would be a little less crabby.”
At that, Sam wiped around to face his older brother, beautiful hazel eyes burning with contempt and a hint of something else that Dean couldn’t quite put his finger on; all he knew for certain was that look made his skin feel molten hot, and his heartrate skyrocket.
“Maybe he wasn’t any good?”
Dean’s mouth fell open in shock when he registered Sam’s words, chest tightening, nausea washing over him like a fierce ocean wave. Holy fuck. Did his little brother just come out to him?!
“He?” Dean asked weakly, barely able to hear himself speak over the sound of his heartbeat pounding in his ears.
“Yeah, Dean, he. Y’know? The guy I let bend me over and fuck my ass. He wasn’t that great, to be honest. And I ended up having to get myself off. Maybe that’s why I’m crabby? Did ya ever think of that?”
“Jesus, Sam! I don’t wanna hear this shit.”
In response, Sam let out a cruel, condescending laugh as he sat down on the foot of his bed, never breaking eye contact with Dean.
“Why? Cause you can’t stand the thought of your little brother loving cock? Cause I do y’know Dean. I don’t care where he puts it either, my mouth, my ass, I’d take a cock anyway I could get it. Especially from a man who knows what he’s doing. I mean, fuck, give me someone with experience and I’d be happy to ride that daddy into the sun.”
“Shut the fuck up, Sam!”
Dean was livid, body shaking from head to toe, cheeks heated and flushed. But that wasn’t even the worst part. Oh no. The biggest problem Dean had at that moment was not the fact that he was on the verge of hulking out, it was because he was half fucking hard. Listening to his little brother talking about getting fucked had gone straight to his dick. What the actual hell?! And he thought Sam was the one with issues.
“What’s a matter De, that bigot brain of yours about to explode?” Sam taunted, gaze traveling down the length of Dean’s body, eyebrows shooting up in surprise when he reached his brother’s crotch. “Or, are you jealous?”
“What? No! Of course not, dude! You’re my brother, I just don’t wanna hear about you…y’know, like that.”
Gah. It was useless. Dean wasn’t fooling anybody. Not himself, and certainly not Sam
“Oh, really? So if I told you about how I came so hard buried deep inside a hot, soaking wet pussy before Tyler fucked me, you won’t wanna hear about that either?”
Ah. So Sam was bisexual, not gay? Good to know. Truthfully, that fact wasn’t that surprising when Dean really thought about it.
“Sam, stop talking.”
“You shouldda seen it, De, the way she looked when I was pounding her tight, sweet little cunt. Fuck, I filled her so full I bet she could taste it.”
“Goddamnit, Sam!”
Dean’s cock was throbbing, heavy and rock hard, visible plain as fucking day through the thin cotton material of his pajama pants.
“It’s okay, big brother,” Sam purred, making Dean’s mind ex-fucking-plode when he laid back on the mattress, lifting his hips up so that he could pull down his boxers, exposing his huge, leaking cock. “You can have me too.”
“Sam…don’t,” Dean tried to protest, frozen in place with fear and anxiety as Sam let his boxers fall to the floor before getting up from the bed to walk over to his brother. Smiling as he stood in front of Dean naked and hard, without an ounce of shame.
“C’mon, De, it’s okay. I want you to fuck me. God, I want you to bend me over and fuck me right. I bet you’re so much better than Tyler. Bigger too. I wanna feel that giant cock of yours splitting me open, big brother, want you to hold me down and make me take it.”
Dean sucked in a sharp breath when Sam slid his palm over his erection, cupping him through his pajamas. They were impossibly close now, the heat from his little brother’s body making Dean sweat like a whore in church.
“We…I…I can’t…It’s wrong, Sam. We’re brothers…and you’re high, I don’t wanna take advantage of you.”
“I don’t care if it’s wrong, De, I want you,” Sam begged, grip on Dean’s cock tightening as he leaned down to nip at his brother’s jaw. “I want you to take advantage of me.”
“Fuck,” Dean moaned, hating himself for being turned on by the filth that was coming out of his baby brother’s mouth.
“C’mon Dean, fuck me. You don’t even have to prep me, baby, you can just bend me over and slide right in. Would you like that? Fucking my slutty little hole, still open and wet with someone else’s cum. I bet you would. I also bet you want to fuck me hard, don’t ya? You wanna fuck me into the mattress, leave bruises, wanna pump me full of your cum until every trace of Tyler is gone and you’re all that’s left. The smell of you on my breath, my skin, your marks all over my neck and arms, making damn sure everybody knows who I belong to.”
In a flash, Dean had his fingers tangled in Sam’s hair, grip tight and unyielding as he crashed their lips together; the kiss possessive and frantic, more teeth than tongue. He could feel Sam’s hands, firm and warm, against his hips, the older boy maneuvering them backward, taking care to make sure his unsteady little brother didn’t fall, until the back of Sam’s knees hit the mattress.
“You filthy little tease,” Dean growled into Sam’s mouth, teeth sharp against his bottom lip, tugging at the small, silver hoop protruding from it. Sam moaned loudly in response, allowing his brother to spin him around, Dean pushing him down onto the bed roughly. And once Sam was on his hands and knees, Dean slipped his fingers between his ass cheeks, gently brushing them over his sensitive, fucked out hole. “You think you can just run around breaking my rules without there being any consequences? You think you can stay out late without telling me what you’re doing? That it’s not a big deal to make me sick with worry? You think that I’ll just excuse that kind of reckless behavior, just roll over and play nice cause you offered to take my cock?”
“De, please!” Sam mewled, letting out a strangled plea when Dean’s right palm connected with his ass cheek, the younger boy surging upward in surprise.
Dean delivered several more sharp, hard smacks to the same spot on Sam’s ass, not letting up even when his little brother begged him to stop. And by the time Dean was done, the area was hot and welted with the shape of his hand print; Sam’s skin bright red and tingling, pain and pleasure dueling for domination throughout his quivering, tense body.
“Shouldda spanked this cute little ass raw the minute you started disrespecting me,” Dean said harshly, grabbing a handful of Sam’s sore, throbbing ass.
“That would have been difficult,” Sam gritted out, body thrumming with anticipation.
He was quite aware that Dean had taken a couple steps back, his big brother leaving him aching and desperate. And although Sam couldn’t see the older boy, he was pretty sure he knew exactly what Dean was doing and the thought made his toes curl for all the right reasons.
“And why’s that, Sammy?”
When Dean closed the gap between them once more he was completely naked, pressing into Sam lightly with the slick, pulsing head of his cock.
“Well, considering you’ve been too busy treating me like a ticking time-bomb,” Sam managed to chuckle just before letting out long, obscene groan, Dean pushing inside him agonizingly slow, making him feel every single inch of it. “I d-on’t- th-ink yo-u had it in ya un-til now.”
“Mm, maybe you’re right. But that’s over now, Sammy. You wanna act like a mouthy little whore? Than that’s how I’m gonna treat ya.”
Dean’s voice was rough with lust, hands digging bruises into Sam’s hips as he held the younger boy steady, so deep inside Sam that he could hardly breathe.
“Are- are you gonna fuck me like a whore, De?”
“Yeah baby, I am. Cause that’s what you are. You’re a filthy little whore that needs to be taught a lesson.”
Without warning, Dean pulled out of Sam almost completely before snapping his hips forward with malice. He drove his cock hard and deep into his little brother, Sam’s abused hole still loose and slick with lube from his previous fuck.
“Oh God, yes! Do it, Dean, please!”
Pounding into Sam relentlessly, Dean reached up to grab a handful of his brother’s messy black hair, using it for leverage as Sam mewled and squirmed, face smashed against the sheets to muffle his screams.
“You’re mine, Sam, you understand me?” Dean asked through gritted teeth with a hard smack to Sam’s right ass cheek.
“Y-yeah, I und-erstand, D-ee.”
“Damn right. Now tell me, Sammy, did Tyler make you feel this good? Has anyone ever made you feel this good?”
Sam could barely think, let alone speak as Dean’s cock drilled his prostate repeatedly, fingernails digging half crescent shapes into the meaty flesh of his ass.
“N-no, God…no, Dean, just you!”
“That’s what I thought,” Dean growled, his words practically dripping with cockiness.
“Oh! Fuck yes!” Sam cried out when Dean suddenly slipped the hand that wasn’t tugging on his hair around the younger boy’s body, wrapping it around his cock to stroke him fast and rough.
“Now, be my good little whore and come.”
As if on command, Sam did as his brother instructed and came impossibly hard, making a mess of the sheets beneath him.
“Jesus, Dean!”
Sam moaned, throaty and loud when Dean followed his lead not two seconds later, pumping him full, so hot and wet; feeling his brother’s body tense and shudder as he fucked Sam through his orgasm until they were both panting and sated.
Slowly, Dean pulled out of Sam, the younger boy collapsing onto the mattress, not giving two shits about the sticky mess below him because he felt awesome. The exchange had been rushed and rough but it was seriously some of the best sex Sam had experienced in…well, ever. And even though he’d never admit it out loud, Sam knew that being with Dean like that was just as much responsible for how incredible he felt as his orgasm was. Just knowing that it was Dean’s cock inside him, Dean’s hands on his body, was practically enough to make Sam come untouched, so he’d known the real thing had to be fucking spectacular.
And as it turned out, he wasn’t wrong.
“You okay, kid?” Dean asked, shaking Sam from his thoughts as he crawled up onto the mattress, draping himself over the younger boy’s back.
“M’great.”
“Psh, you’re still high.”
“Doesn’t matter, that was amazing,” Sam sighed contently, closing his eyes and snuggling down.
He could feel Dean running his fingers through his hair, the older boy’s warm, naked body pressed firmly against his back, weighing him down like an anchor.
“You know this bullshit’s gotta stop, right? You’re headed down a dangerous path, Sammy, and I can’t sit back and watch you fuck up your life cause you’re mad at dad or me or whoever.”
“I’m not mad at you, De. Never at you. It’s the rest of the population I have an issue with.”
“You ever gonna talk to me about it?”
“Yeah,” Sam mumbled, his shaky voice betraying his calm demeanor. “…but can we please save it for in the morning? I promise we can talk then…about everything.”
Dean let out a frustrated huff in response but leaned down to kiss Sam’s flushed cheek all the same. He wasn’t looking for to discussing what they’d just done, but he knew it was a necessity. Just like it was prudent for Sam to tell Dean what was going on in that big, dumb head of his.
“Fine, but we are going to talk, Sam. Even if I have to beat it out of you.”
“Mm, I’d rather you fuck it out of me.”
“Oh my God, shut up, bitch.”
“Bite me, jerk.”
Chuckling, Dean nosed at the side of Sam’s neck, chest aching with love and devotion as his little brother’s body went lax beneath him, breathing becoming shallower.
They were going to be okay. Sam was going to be okay. He just needed time.
“Good night, Sammy,” Dean whispered, pressing one last kiss to his Sam’s soft, pink cheek.
“G’night, De.”
