Timeshift

Um. AU.



Adult!Dean was turned into Teen!Dean. He thinks he's in an alternate reality or something, where his whole family is dead. He doesn't know Sam is Sammy. Or maybe he does. I dunno, PWP, guys. :)

“Holy fuck.” Dean breathed, eyes wide.

 

Sam paused, hands wrapped in the towel he was using to dry his hair. He was so used to - to Dean - that he hadn't thought twice about walking out naked. Judging by his now 14 year old brother's fixed - and rapidly impressed - gaze, he probably should have.

 

“Dude!” Dean cheered. “I didn't think dicks could even get that big. I mean, I've seen a porno or two but.. I just figured it was all special effects, you know?”

 

Sam snorted a laugh, shaking his head at Dean's unabashed admiration even when he didn't know they were brothers, only to freeze when Dean's admiration turned decidedly anticipatory. Without a word, his little-older-brother started stripping off the soft pants and sweats he'd donned after his shower.

 

“Woah, wait, Dean!” Sam blurted. “What are you doing?”

 

Dean paused long enough to shoot him a look that questioned Sam's intelligence far more thoroughly than any adult version could, then kept stripping.

 

“I'm getting that monster cock in me, that's what I'm doing.” Dean asserted, head inside his shirt. “You think I'm passing that porno-worthy meat up? Fuck that, it's as thick as my fucking forearm and you're not even hard yet!”

 

Yeah, that wouldn't be a problem for long, Sam thought, as his eyes kept rebelliously flicking down to drink in Dean's so-smooth, toned, teenaged physique. Last time around, when Dean was fourteen, Sam had been ten and Dean had seemed big and strong and very, very platonically his brother.

 

Now he was so short, so slender. So tiny. So breakable. Sam could pick him up like a feather, would be able to fuck his brother on his cock using nothing but his own strength. Could split that probably-virgin ass hole open, could stuff his unknowing brother full of cum and make him take it. There would be no contest, no struggle, nothing that would register. The difference in their physique, in their strength, was too great.

 

Through sheer will, Sam turned away. His cock, as rebellious as the rest of him, was already half-hard and racing for full.

 

Dean saw it and smirked.

 

God how could that lecherous smirk look so innocent and so filthy at the same time. Maybe it had something to do with Dean's child-big green eyes, the freckles faintly painting his nose or simply his small stature.

 

“No, Dean.” Sam said as firmly as he could, though the effect was somewhat spoiled by the fact that he couldn't look over at Dean without his cock twitching and filling further. Christ, did his brother have to... kneel like that on the bed? Knees obscenely wide, his little cock stiffening rapidly, his entire body an invitation to fuck.

 

He closed his eyes. Swallowed. Reminded himself that he'd beaten Lucifer, so he could fucking keep himself from fucking his brother.

End of story.

 

“I said no. Now go to bed.”



So saying he flipped off the light and got into the nearest bed - his old one furtherst from the door by habit, not the one closer to the door that he'd started sleeping in once Dean woke up twenty years younger than he should have been.

 

Which also meant there was no pair of pajama pants waiting under the pillow for him. Fuck.

Resolute, he turned over and forced his brain to sleep. It wouldn't kill him to sleep naked. It would kill him if he went to the other bed to grab his PJs, only for his brother to proposition him again. There was only so much mental strength he had.

 

{}

 

An unknowable amount of time later, he woke up. Dean was lucky that Sam's subconscious still saw him as Dean because anyone else sneaking up on him whilst he was sleeping would be asking for a quick snapped neck.

 

Sam was on his back, his dick was stiff and Dean had somehow snuck under the blanket to hover over him like he was planning to ride Sam in his sleep.

 

“Dammit Dean!” Sam snapped, grabbing Dean's upper arms - hard. “No means no!”

“I know you want to!” Dean argued, a whining tone to his voice. “Look how fucking hard you are! You wanna tap this, Sam, and I swear my ass wants to be tapped!”

 

Sam swallowed, hard enough that Dean could hear it. Dean stretched a bit, snapping on the small bedside lamp with a smirk.

 

“Just because I...” Sam floundered, not wanting to bring up we're brothers to his fourteen year old partner who was currently trying his best to seduce him. Adult Dean had been okay with it - eventually - but young Dean? No chance. It had taken Hell for them both before Dean had been okay with sexing up his little brother.

 

“It's not right.” He said firmly. “I'm sorry, Dean. I just can't.”

 

“Fine.” Dean snapped. “Leggo 'o me.”



Sam sighed, half in relief at finally getting through to his horny little brother and half in cock-blocked frustration at himself. His dick certainly wasn't happy, standing flush and full and practically begging to sink inside his brother's tiny, tight little ass.

 

Dean shoved back, rising up on his knees to stand-

 

Then with hunter-quick movements grabbed instead for Sam's cock and shoved himself down onto it.

 

Sam cursed, bucking reflexively as his hands flew back to Dean's upper arms. Dean swore too, as his - thankfully pre-lubed, the cocky little shit - hole was abruptly impaled with three more inches of Winchester cock.

 

Sam might have reflexively yanked him off and thrown him across the room had Dean's “Fuck!” not turned into a groaned “yeeeeaaaaahhh...” as his head tilted back, his shoulders following as he clumsily sought out Sam's leg, the bedsheets, and tried to pull/push himself down further.

Sam felt Dean's hole stretch further, felt his tight channel opening up for his cock. Surrendering to him, flexing and fluttering around him as Dean groaned and whimpered in pleasure and pain both.

 

And there was still nine inches to go. Sam's name might not have been on record as the bearer of the biggest penis in the world, but he had the guy who was, beaten by a half-inch.

 

And he was thicker, too. It was something he'd used to enjoy knowing that Dean knew.

 

This Dean would probably be impressed too. Well, unless Sam chose to also share that, actually, he was his little brother Sammy as well. He didn't think this Dean would be very happy about that part.

 

As his fourteen year old brother grunted and grinded and tried to force himself down even more, Sam privately resolved not to ever breathe an incestual word.

 

And not just because he was pretty sure he'd die if Dean pulled off of him right now.

 

Noting Dean's expression was tipping towards a mixture of frustration and pain (and maybe a hint of embarrassment), Sam slid his hands from where they'd been mindlessly holding his arms, down his sides to span his ass, hands large enough for his thumb to rub in the V of Dean's abdomen.

 

Dean shuddered in pleasure and tightened up.

 

“Fuck, your fuckin' hands.” He muttered, almost slurring his words.

 

“Maybe later.” Sam parried automatically, earning a startled - then considering look from the teen on top of him. Shit, it was weird how... how fucking innocent his little brother was. Current riding of his cock notwithstanding.

 

“Here.” Sam gave up, steadying his brother with one hand whilst he used the other to push himself carefully up. Dean gasped and scrambled to hook onto his shoulders as Sam shifted himself - and Dean - carefully until Sam was standing and leaning against the back of one of the bolted-down chairs and Dean was sitting on his cock - and nothing else. With nothing else to take even a bit of his weight - Sam was just guiding his balance by this point - Dean sunk down another painful three inches.

 

Whatever lube he'd stuffed himself full of had almost certainly come from Sam's own duffel, he noted absently. In the past... well, it paid for something thick that spread well and didn't dry out easily. Still.

 

He lifted Dean up, muscles barely rippling as they hefted his brother's weight. He pulled a complaining brother up until his clenching hole released his cock and a gush of lube followed the suction.

 

“Rest your weight on my shoulders.” He ordered, Dean complying automatically as he twigged that Sam wasn't actually going to stop fucking him just yet. Sam was then able to free up one hand to carefully slide a finger into Dean's hole - to which his brother writhed and moaned like a well-paid whore - and confirm that it was still well slick inside.

 

“What did you do, give yourself an enema?” He muttered, half-amused as he carefully stroked the excess at the top of his cock down to cover the rest.

 

“Tried.” Dean grunted, his arms trembling a bit as they held all his weight on Sam's broad shoulders. He couldn't look to see what Sam was doing without unbalancing them. “I got our toothbrushes - you might want to get a new one, by the way - and stuck 'em in, the handles, used 'em to try and hold myself open. Then I just squeezed as much of that tube of lube up inside as I could. Used the handles to shove it up further, much as I could.”

 

Fuck that was hot. In the dead of night, his jail-bait little-big brother holding himself open and filling himself up with lube in preparation to take Sam's huge cock.

 

Without a word of warning, he grabbed Dean's hips and yanked him down into a brutally hard fuck up.

 

Dean screamed, burying the sound in Sam's shoulder after the first squeal. His legs hung open wide, instinctively trying to ease the pressure. Sam loved it, loved how slutty it made him look.

 

“That's it.” He said tightly. “You wanted my cock in you, Dean. You fuckin' wanted it. So take it.”

 

He rocked his hips, pulling out an inch and fucking back in two more. Slowly, steadily, he fucked the boy open. Determined not to come until Dean's pert little ass rested against his balls, he ignored Dean's whimpering discomfort and forced himself in, further and further, forced Dean to take him. It wasn't until he finally got there, had stuffed his cock deep inside his brother, that he paused.

 

His shoulder was wet with Dean's tears, he could feel the boy biting his lip - hard.

 

“How does it feel?” He asked, aiming for soft but not quite managing it. Not when Dean felt so good, so impossibly tight. He imagined that if he pushed the boy back, he would see the bulge of his cock pressing against the boy's abdomen.

“Still want this 'monster cock'?”

 

For a split second, he wanted his brother to say 'no'. Wanted him to ask him to pull out, eyes averted and wet with pain and shame. Wanted to see his face change, his eyes widen and lips tremble as Sam refused.

 

Proof that if he was any kind of good guy, he never would have shoved his cock into his brother in the first place, he supposed.

 

But Dean didn't back down. True to form he took a deep breath, shoved the pain back and put on the front Sam had come to know, hate and love.

At fourteen years of age, however, it was still a little shaky.

 

Split open on Sam's cock, it was cracked with pain and helplessness.

 

“Well?” Sam asked, injecting his voice with a little impatience. “If you think you can't handle it, say so.” When Dean hesitated, he added “I told you so.”

 

That did the trick. Dean's expression hardened and Sam waited.

 

“Fuck you.” Dean's voice cracked, but he cleared it and went on. “'s that all you got, grampa?”

 

Sam grinned, and it felt wolfish.

 

Dean barely had time to swallow - nerves widening his eyes - before Sam had Dean lying on his back on the table, Sam's hips pistoning his cock in and out of that tiny little hole. The tiny little hole now stretched obscenely wide around his red, blood-flushed cock. Fumbling with one hand, Sam found his phone and discretely switched on the recording function. Dean, from a time when video recorders looked like a silver brick and being fucked out of his mind to boot, didn't notice.

 

If the table hadn't been bolted down, it would have slammed into the wall. As it was, Sam had to keep one hand tightly wrapped around Dean's knee, using it to both keep the boy in place and yank him open and up, twisting the angle of penetration in an attempt to both unsettle and pleasure his brother. He knew exactly where Dean's spot was, but this was about stretching and fucking his brother more than it was about pleasuring him. At least, right now it was.

 

Sam's eyes flicked from cell screen to teen fuck-puppet, watching his own cock shove in and out, making sure the phone got it as well as Dean's stiff cock bouncing back and forth, his head tossing and turning with overwhelming sensations and his hands gripping the edge of the table behind him tightly - to keep Sam from fucking him over the edge of it as much as to fuck back into Sam.

 

Spying a rubbed band out of the corner of his eye, Sam gave a wicked grin. Propping the phone against the TV to continue recording, he snagged it and gave it an experimental stretch. This had to be carefully done. Too tight could damage his brother, after all.

 

It seemed right, though, so Sam quickly and dexterously snapped it tight around the base of Dean's cock, which had finally flushed hard enough that a climax seemed imminent. At the tight, unpleasant feeling, Dean arched up - eyes wide.

 

“You'll like it.” Sam promised, voice a good two octaves deeper. Dean visibly shuddered at the sound of it. Sam wondered if his brother realised how much he sounded like their Dad right now.

Still, with both hands free, he pulled Dean closer and lifted his hips up - arching the boy's back uncomfortably but giving himself the perfect angle to nail Dean right there.

 

“Ah! Ah fuckfuckfuck!” Dean gasped, moaned, in time to Sam's thrusts. “Fuck, I'm gunna... gunna..”



“No, you're not.” Sam smirked, sweat dripping from him as he hammered Dean's ass. “But I am.”

 

So saying he shoved himself in to the hilt and came explosively, shooting load after load into his brother's already crowded body. Dean cried out and flailed, frustrated and on the edge and too-full, hurting and horny and wanting more and wanting away all at the same time.

 

“Monster cocks come with monster loads.” Sam grunted, shoving a time or two more, hard, to milk himself with Dean's hole. In truth it was more like 'monster times without any fucking sex, followed by a cockslut little-big brother comes with monster loads' but that took longer to say.

 

“And if you think that's too much,” he added, knowing from Dean's pained shifting that it certainly was. “Then think again. I'm not going to let you come until you're fucking leaking with it, have sucked me hard again and are riding me - my monster cock shoving my cum deeper into you with every thrust.“

 

Dean fucking blushed, his fair skin turning red from his ears down to his bellybutton.

 

“Fuck you're so fucking gorgeous.” Sam groaned, bending down to suck Dean's pebbled nipples into his mouth, one at a time, rubbing them with his tongue and lightly chewing the skin around them.

 

“Shit!” Dean yelped, hands flying to Sam's hair. Judging by the way they clenched and didn't move, Sam figured Dean had no idea that being suckled could feel so good.

 

Sam had once joked that it was because Dean was a woman on the inside. After he woke up with breasts drawn on his face - with his eyes for nipples - and lines making his mouth look like a giant sideways vagina, he never joked about it again.

 

Sam was softening inside Dean but one of the perks of being naturally thick down there was that for probably-virgin boys like Dean, it still served perfectly well as a plug to keep most of his cum inside. Part of his brain started working on what he could use to plug Dean with whilst the boy sucked him hard again, because as much as he wanted Dean's little mouth stretched around his cock, a primitive part of him also wanted his seed to stay inside his hole.

 

He fantasized briefly about a magazine clip but... no.

 

As he licked and sucked and bit, Sam's hands stroked his brother all over. Up and down his thighs, trailing light fingers over the sensitive inner skin, pulling his legs wider, tugging the boy's body into him, using his sheer length of his cock - which was already twitching a bit - to make it feel like he was still fucking him. Dean groaned, his own hands falling away from Sam's hair to run over the muscles of his back and arms, his hands feeling so small and soft.

 

“Please, Sammy.” Dean moaned, still hard and on the edge and desperate. Sam almost almost froze, but Dean was lost in his own head - hadn't meant it like that.

 

Still, Sam pulled him closer and up, careful not to let his cock slip out of his brother as Dean wrapped his arms and legs around him and rutted painfully against his abs, mindlessly trying to come as Sam cast a quick look around for something... there!

 

He grabbed the cell phone and tossed it onto the bed, then picked up the complimentary motel phone and tugged the clip-in wire out of the base of the handle. It was old-fashioned but not actually old, meaning that it was fairly narrow and light despite having large rounded 'heads'. It would serve as a functional buttplug, as Dean's hole closed around the narrower bit and was handily curved to make playing with it easier.

 

He dropped Dean onto the bed on his back, tugging Dean's hips up high - he was a tall guy after all - to help keep the cum in as he slowly worked his cock out. Slow was key, to help prevent a flood from the change in pressure. Then, the second he could - with Dean catching only a glimpse of what Sam was about to shove inside of him - he forced the head of the phone in, licking his lips as Dean's abused hole stretched wide around it and cum slipped out through the gap, before sucking it abruptly in as the widest part passed the outer ring of muscles.

 

On the bed, Dean gasped. Sam watched him and gently but steadily pushed the phone further in, then out a bit, then in again, slowly fucking him with the hard and cold plastic. Dean practically cried, writhing on the bed, especially when Sam rotated the phone inside him and rubbed it firmly against his joy spot.

Dean arched, swearing.

 

Absently, Same checked his phone to make sure it was still recording - it was mostly catching the ceiling but at least he'd have these fucking wonderful sounds to jerk off to later - just as Dean started begging.

 

“Please, Sam, please! Fucking- lemme suck you, please! I need-I gotta-fuck, wanna fucking ride you already, wanna cum when you're splitting me open, please!”

 

Yeah, that was something he'd love hearing for the rest of his life, over and over, in Dean's thin, young, desperate voice.

 

He lowered Dean's hips, the curve of the phone making it press into Dean as his ass rested against the bed. Dean moaned and shifted, each movement just making it rub inside him some more. Sam paused for a second, watching the teen almost fuck himself on it, then straddled his chest. Like this, the differences in their size was even more obvious. Sam's thighs were heavily muscled and huge when supporting his weight like this. Dean's chest and whole fucking body just looked so thin and delicate.

 

As Dean blinked hazily up at him, Sam grabbed the pillows and quickly re-arranged them, then hauled Dean up onto them - Dean groaned as the new angle pressed the phone deeper and harder inside him. Thinking quickly, Sam stuffed another pillow - folded for firmness - against the phone so that when Sam began rocking the movement of the bed would have Dean be half-fucked by the phone.

 

The tease of sensation would drive him crazy.

 

Dean seemed to only just be twigging as to what Sam was planning when Sam pressed his cock against his lips, smearing lingering cum and lube against them.

 

“Open up.” Sam growled, voice deeper than it had ever been before. He wanted to grab Dean's face, thumb open his jaw and fuck his little mouth - but he wanted Dean to actively fellate him more.

 

“Get me hard.” He ordered. As Dean glanced nervously from Sam's half-hard cock up to Sam, through his lashes, Sam knew it wouldn't take much.

 

“Take my cock into your mouth.” He instructed, voice still commander-hard. “Wrap those slutty lips around it. Suck it, lick it, get it nice and wet so you can fuck yourself on it nice and easy.”

 

He nudged it against Dean's lips again and fuck it if his brother didn't obey, opening clearly-hesitant lips and leaning forward to engulf the head.

 

“That's it.” Sam grunted, shoving forward another inch or two. Dean choked a bit, hands lifting to Sam's hips, but he didn't pull away.

 

“Let's see how much you can take.” Sam needled. “See how tough you really are. Suck me until it fucking chokes you, until I can shove it down your throat and fuck the voice right out of you.

 

Dean groaned, flushing again but obviously turned on. His technique was almost non-existent and messy, but he was enthusiastic and seemed to have something of a natural talent for sucking cock. He rubbed Sam's cock with his tongue, suckled and sucked, licked and mouthed and hummed. He fucking worshiped the cock in his mouth, his pretty little lips stretched so obscenely around it, shy green eyes flicking up occasionally only to dart down again after meeting Sam's intent stare.

 

“Look at me.” Sam ordered, starting to rock his hips a little as his cock filled out. This wasn't the best angle to really fuck down Dean's throat, but he wasn't against making it seem like he would. The movement made the phone-plug in Dean's ass rock too and Dean practically inhaled more of his dick, desperate for it as his body was rocked with pleasure/pain/need to cum. He sucked and rubbed and swallowed like he could come himself if he did it hard enough.

 

Sam just enjoyed himself, rocking shallowly into Dean's mouth as the boy looked obediently up at him, his eyes blown with sex  as he let himself be used so degradingly.

 

“That's it.” Sam crooned. “There's my good little cockslut. Just gagging for it, aren't you? You'd suck me off right now, wouldn't you? Suck me off and swallow my cum and beg for more. You'd suck me hard again, just so you'd have another chance at riding it.”

 

Dean moaned - agreement or denial, it didn't matter. The vibration stiffened Sam even more, his cock really filling out now, meaning less could fit in Dean's mouth at once. He teased a bit at the back of Dean's throat, testing his gag reflex. Unfortunately, it was too strong at the moment to just go ahead and do what he'd suggested. Little spoiled the mood more than vomit on your cock.

 

“Almost there.” He murmured, keeping Dean's gaze locked in his own. Without looking he reached back with one long arm and started actively fucking his brother with it, brutally, feeling bits of lube and cum leak out as he did.

Dean choked, whimpered, struggled against him and sucked harder, actively bobbing his head now even as his eyes slipped closed - too lost to the feeling.

 

“Do you like it?” Sam asked, thrusting his cock back and forth, rocking into Dean's sinful little mouth. When he pulled out enough, Dean's tongue followed him, licking all around the head of his cock like the hungry whore he looked. Dean himself craned after him, mindless, maybe equating the sucking with the fucking.

 

Realising that if he went on much more, the boy would have to swallow his load, Sam pulled back and off, quickly yanked the boy up and over him, pulling the phone out with a wet squelch and a sharp cry from the teen just before he slammed him down onto his cock once more.

 

Dean cried out again, the sound unmistakably wanton. Sam imagined any neighbours were getting an earful.

 

“That's it, baby.” Sam muttered, yanking blindly at the pillows to make himself more comfortable, semi-reclined and snatching at the phone. “Just rock your hips a little. Push down against me. Feel that pressure? That's my cum still inside you, you're fucking my cum deeper inside your belly.”



Dean moaned louder at that, head tipped back and eyes still closed. Sam tugged the band away from the boy's cock and Dean came - hard and unexpectedly, judging from his yelp. Sam tilted the boy's penis so most of it spattered over Dean's own chest. He bit his lip as Dean clenched around him as he came, but having come so hard once already made it easier to resist.

 

“Good boy.” He murmured, as Dean wound down. He was counting on Dean's conditioning -and on his youthful stamina - to keep him following orders. He could have kept Dean bound up but he wanted the boy to really work for this, to fuck himself knowingly on Sam's cock, to hear and feel himself squelching and leaking with cum but still bounce himself up and down, to work Sam like a whore.

 

With his free hand, he gently massaged Dean's balls and cock, which had to be pretty sore. Under the cover of that obvious sensation, he pushed his hips up and down the slightest amount, rocking Dean on his cock so subtly he doubted the boy would consciously realise it.

 

Dean moaned and leaned forward, limp as a doll, but almost unconsciously rocking his own hips into Sam's hand and cock.

 

“Gonna ride me?” Sam pushed. “Ride me like you said you would? Like you said you wanted? Fuck yourself on my cock until you come?”

 

Dean groaned and shoved himself up. Muttering something that sounded a lot like 'dirty bastard', his rocking turned more purposeful and he groggily got his legs under him to help him rise up.

 

“That's it.” Sam approved. “Good boy.”

 

Dean's cock twitched, already filling again. Sam's lips twitched as Dean himself blushed a little, but obediently started bouncing on Sam's rock-hard cock.

 

“That's it?” Sam worked hard at drawling. “A little bounce is all you can manage? It's barely moving in you.”



Dean glared, but - true to expectation - got his feet and knees under him to really rise up off the cock - a good four-five inches - and slam down again. He winced - Sam's cock was still fucking huge and long and was punching not only into Dean's body but also shoving a hell of a lot of cum deeper into him - but grit his teeth and kept going.

 

Sam lay his head back and groaned himself.

 

“That's it.” He muttered. “That's my good little cockslut. Ride my cock, baby. Fuck yourself on my monster cock. 'S fucking splitting you open, isn't it?”

 

Dean ducked his head, fringe bouncing along with the rest of him.

 

“..yeah..” He answered, something Sam hadn't really expected but certainly welcomed.

 

“Speed it up, baby.” Sam crooned. “Roll your hips a little - yeah, like that. Feels good, doesn't it? My cock all up inside you.”

Dean moaned, his own cock filling again.

 

“Yeah.” he breathed more readily, as riding Sam's cock became less about pride and more about pleasure. “Fuck, Sam... you're so fucking huge. I can barely take it.”

 

“But you are.” Sam praised. “Taking it like a champ. A champion slut. I swear I can see the edge of my cock, pressing up against your insides.”

 

Dean groaned and rode him faster, eyes still tightly shut but obviously even more turned on.

 

“Gonna fill you up, baby.” Sam crooned. “Gonna fuck you full of cum and make you sleep with it - make you sleep with my cock inside you too. You'll wake up tomorrow with it already hard up inside your slutty hole. Maybe I'll just roll over and fuck you into the mattress, give you some fresh jizz for the day.”

 

Dean was panting now, rocking and rising and dropping, fucking himself on Sam's cock like a thing possessed.

 

“Or maybe I'll plug you up again.” Sam panted a bit himself, his body rocking with Dean's movements. “And order breakfast in. You can kneel under the table and keep my cock warm in your mouth whilst I eat, then you can swallow my cum for your own breakfast.”

 

Dean moaned, a desperate, gut-punched sound. The bed was squeaking non-stop as the fourteen year old put his hands on Sam's chest and fucked himself up and down for almost half Sam's full length. Every downward slam was accompanied by a bitten-off whimper as pleasure fought against too-much pressure and pain.

 

“Like that?” Sam asked. “Huh baby? Like the idea of being my cockwarmer? Letting me keep my cock in your hole, any hole I want, any time I want?”

 

The sound Dean made was pornographic beyond belief.

“Yeah-yes!” Dean gasped, eyes still shut tight. “Want you- in me. Fuck, always want you in me, Sammy. My mouth, my ass... ugh... uh... ah! Fuckin' yours... Love your cock... love having it inside me... love your cum all w-wet and w-warm... in-insiiiide... uhhhhhhh!”

 

With an all-body shudder that was almost a convulsion, Dean came. His dick spurted more ropes of cum, long and lasting compared to his last round. As his hole clenched around Sam, Sam grabbed his hips and fucked up into him, hard. Then, that not quite enough, he rolled them over and jackhammered into the boy, slamming his full length in and out as Dean gasped and moaned and hooked his legs around Sam's waist.

 

His eyes were open, blown wide and looking at Sam as though there was nothing else in the world.

 

“Uh! Sam!” The sounds were punched out of him. “Ugh... un... uhn....c'mon... need it... fuckin' fill me up, please!”

 

Despite the fact that he'd already come, Dean sounded beyond wanton. His tight little hole fluttered and clenched deliberately and Sam leant back - grabbed his knees - and stretched his legs wide. Dean just looked up at him, spread open and speared on Sam's cock, and begged for more.

 

“Please, please... Sam please, fuck yeah, fuck.. fuck...”



Sam slammed into him, shallower and faster, it had to be painful but Dean's eyes were almost rolling in his skull.

 

“Fuck your cockslut!” Dean gasped, mindless, and Sam came.

 

The world whited out for a bit, as pleasure beyond anything slammed into him.

 

He roused enough to shift Dean, the boy grumbling a bit as his own cock had already moved to half-hard from Sam's powerful automatic fucking of his prostrate, onto his side. He kept his cock - and cum - inside the boy, just like he'd promised, moving one of Dean's legs forward to accommodate his own but otherwise just pulling the boy snug against him - onto him - and drifting to sleep with his little-big brother still fucked open on his cock.

 

Dean rutted back against him a little before falling asleep as well. He dreamed of Sam driving them somewhere, Dean stretched out on the seat, his head in Sam's lap and Sam's flaccid cock being suckled lightly in his mouth and half down his throat. He dreamed of the end of a long day, lying sleepy against Sam's chest on the couch as the sports channel played quietly and Sam slowly rocked another load of cum deep inside him.

 

Dean knew he would find that being Sam's cockwarming cockslut was a million times better than hunting ever could be. It sure felt better.
