****** Porn is for losers (and sam winchester) ******
by BuckyGotStucky
Summary
     Sam just really wanted to watch porn, okay?
     He's 16, after all.
Notes
     Fair warning: this sucks

Sam knew that he shouldn't have stolen his dad's laptop while he was out
hunting whatever the hell he was hunting. He knew that stealing was wrong, and
that he could have been doing anythingelse but opening a private tab on this
brand new, very expensive laptop, and typing in perhaps one of the most unholy
websites to have ever existed. With his older brother just across the room from
him, reading some newspaper that couldn't interest Sam in the slightest, he
knew just how wrong it was to be doing this, to make sure the sound was off on
his computer as he clicked on the first gay video he could find; if this was
sin, sin sure did give him quite the adrenaline rush.
"What game 're ya playing now, Sammy? Another one of your dumb wizard games or
some shit?" Sam, completely overwhelmed with lust from watching a two minute
video of some random guy getting fucked in the ass, just gulped and made sure
the laptop was covering his, well, lap. He'd decided to just nod in agreement,
not wanting to open his mouth, for fear that he would only moan; why was this
hotter than usual, now that Dean was with him? The thought of his big brother
walking past him at any moment, looking over his shoulder and seeing just how
naughty he was- no, this was wrong.
That thought didn't stop him from clicking on another video, one of a man
getting tied up and spanked, dominated so easily, as if he were nothing but a
sex toy. He cocked his head to the side at the thought, thinking of what it
would be like for him to be used like that, to feel the rope on his skin and
the sting on his ass, to feel so dirty and wrong. He took his bottom lip
between his teeth, trying to hold back a small whine as his untouched,
throbbing cock twitched in his jeans. It really didn't help that Dean was
staringat him, and Sam was quick to let a whine escape his lips.
"You alright, Sammy? You seem-" Sam nearly panicked, attempting to close out of
the tab as Dean stood up and began walking over to him. Of course, with Sam's
amazing luck, he had encountered a slew of pop up adds and, getting to the last
one, the screen froze just as Dean had gotten behind his chair, "oh, Sammy you
coulda asked me to leave the room or-" Sam slammed the laptop shut, tears
filling his eyes in pure embarrassment as he realized what had just happened.
He reached up to wipe at his own eyes with a sniffle, almost wincing at how hot
his cheeks felt. "Hey, baby boy, there's no need to cry. I'm not upset with
you," Deans hand now rested on Sam's shoulder, caressing it with the upmost
care.
"I-i wanted-" Sam looked up at his big brother with his usual puppy dog eyes,
"wanted you to catch me," and though Sam didn't know whether or not that was a
lie, Dean was happy to go along with it, though he didn't speak in the happiest
tone.
"Sam, that's- that's bad, you know that." Sam looked back down at his lap,
setting the computer back on the floor, "we'll fix that before dad gets back,
okay? He don't have to know what you've been watchin' on there. I've done it,
too, and he wasn't very happy." Seeing the outline of his cock in his jeans,
Sam just whined again, as it twitched and throbbed from being untouched. "Hey,
I know, I'll go-"
"No." Sam looked up at his big brother, biting down on his lips and trying not
to whine again. "No, Dean, p-please help." His voice came out in a mere
whisper, breathy and needier than he'd ever imagined it to be. He squirmed
where he sat, his breath catching in his throat at just how his cock rubbed
against the cotton of his boxers in just the right way.
"Sam, you  know how to jack off, I don't need to- oh," he  watched as Dean
pursed his lips, furrowing his brow in thought, and oh god he wanted to just
scream at Dean to tell him just to get on with it,"I, Sammy..." Sam gave Dean
his best puppy dog eyes possible, sticking his lower lip out in a pout.
"Just this once, Dean, please? I-i just need," Sam cleared his throat in a
failed attempt to sound less whiny, "need you." He watched Dean's eyes widen,
and his cheeks tint to an incredibly wondrous shade of pink. Sam really didn't
know what had gotten over him in that exact moment, basically beggingfor his
older brother to help him get off like a little slut, but somehow, he didn't
care. In fact, Sam really liked acting this way, even if he'd never admit that
in his life.
"Sammy, I dunno if-" with another whine, Dean sighed and let out a defeated
fine, "but if we're gonna do this, you can't tell anybody, got it? And you
can't be too loud, we're in a hotel. You don't want someone hearing us and
complainin' to dad, do you?" Sam, too surprised by the fact that this was
actually happening, couldn't even speak, so he just shook his head and gasped
as Dean ran his fingers through Sam's long, messy hair, sending an electric
shock down his spine as he tugged on it affirmatively. "Answer me." It took Sam
a few moments to gather up the puddle of slum that was his mind enough to
answer.
"N-no, I don't want anyone knowin' and I don't want," Sam was cut off  with his
own long, drawn out moan as Dean tugged at his hair again, "don't wan' anyone
complaining." His throat tightened as he was ordered to stand up, though he did
as he was told; his brother was in charge, after all.
"Now, Sammy, I want you to go strip for me and sit down on the bed, alright?
I'll be there in a minute. And don'ttouch yourself, got it?" With a nod, Sam
obeyed Dean's command, and in what seemed like the fastest time Sam had ever
gotten undressed, he was sitting on the edge his and Dean's shared bed and
licking his lips. He shouldn't have been impatient already, but there he was,
squirming and having to sit on his hands as he waited for his brother to
appear. A small rush of pure ecstasy ran through him for just a moment while he
pondered just what the two of them would do, just how Dean would handle all of
this. His cock throbbed even more as his mind raced through all the
possibilities, and Sam knew that if he had to wait much longer, there was no
way he'd be able to follow Dean's instructions.
When Dean walked into the room, shirtless and holding a bottle of lube, Sam
knew that he couldn't wait. He began to feel an even bigger sense of lust as he
watched his big brother walk over to him, half naked and oh god did he look
good without a shirt on, Sam could've come right then and there, just looking
at Dean. He let his gaze run over Dean's torso, biting his lip as he watched
the toned muscles there flex whenever Dean took a step. Sam could feel his cock
twitch again, though he  couldn't bring himself to care, because the sight in
front of him was quite the sight to see. 
"Mmh," he snapped from his trance when Dean had spoken, "you're so pretty,
baby- fuck, such a little whore, aren't ya?" Sam nodded as Dean took a final
step, spreading Sam's bare legs and standing in between them. The outline of
Dean's cock in his jeans was quite prevalent, and Sam had to restrain himself
from reaching over and unzipping his brother's pants. "Watchin' that stuff with
your big brother in the room- mm, just couldn't wait, could ya? You could've
asked me to leave or gone into the bathroom, y'know," Sam eyed Dean hungrily as
he unzipped his pants, "but ya just just couldn't, could ya? You just had to be
such a little whore.. had to watch that filth with your big brother in the
room, hm? Couldn't wait to get off, bet you wished you were being fucked like
that little slut on screen." It took all of Sam's willpower to keep from
touching himself. Dean's words sent shivers down his spine and made nearly his
entire body quiver with need.
"D-dean, please..." the air in his lungs seemed to escape him all at once,
leaving in a shaky, pleading whine. "Please, I-" He watched as Dean slid his
jeans down his legs, exposing his grey boxers and the outline of his cock
perfectly; damn, it was big. "Dean I can't wait any more," he was nearly
panting with arousal, his hands shaking more than they'd ever shook before with
a desire that he'd never thought he could feel.
"What's that, baby boy?" Sam watched as Dean stripped completely, licking his
lips as Dean, incredibly slowly, pulled his boxers down, "you can't wait, hm?"
Without another word, Sam just nodded, squirming where he sat. "I don't think I
can wait much longer either," for a moment, the two of them locked eyes.
It was in that moment that Sam felt a pang of guilt in knowing justhow wrong
what he was doing was. He began to overthink what was going on, as he always
did, but his thoughts soon went blank as he felt a pair of lips on his. In a
mess of tongues and teeth and lips that could hardly be considered a kiss, the
two of them embraced each other. As Sam laid down, Dean fell onto the bed on
top of him, though he caught himself before he could truly cause an impact.
They shared a brief moment of reality as the two of them erupted into fits of
giggles, before their lips connected once more, and their hips rutted against
each other in the most perfect fashion, leaving them both breathless and
mindless.
Sam could feel Dean's hand in his hair when the two of them pulled apart, and
he could feel himself completely overwhelmed with neediness as Dean's erection
pressed into his thigh. He closed his eyes to try to gather himself, to come
back down to earth enough to be able to pleasure Dean. It didn't take him wrong
to realize that he wasn't coming down, not for quite a long time. When he felt
Dean slip a finger into him, he let out a small gasp at the small burning
sensation there, but his stomach churned from the bit of pleasure it caused
him.
"You okay, baby boy? You gonna be alright?" the caring tone in Dean's voice
would be enough to make Sam swoon if he didn't now have a second digit of
Dean's pressing into his tight hole.
"Ah- mm, Dean 'm good." was the closest thing to a coherent sentence that Sam
could form at the moment, especially with how Dean's fingers felt moving inside
of him, incredibly close to brushing his sweet spot. Sam was close to
completely losing it as he felt a third finger press inside of him, rubbing
against a ring of muscles in the most sinful way, filling him up in a way that
he knew he shouldn't have loved, though at this point, the thought of how wrong
this was didn't even bother to cross his mind.
"Are you ready for my cock, Sammy? Ready to take it in the ass just like that
guy in the porno you were watching, huh?" It took all of Sam's willpower to
even muster a nod as Dean pressed his fingers even further inside of Sam with
that same mischievous smirk he'd held nearly every time he merely looked at
Sam. "Mm, so ready you can't even speak." Dean's fingers pulled out of Sam,
accompanied with a slow, tedious burn that somehow sent a rush of something to
Sam's cock.
The click of a bottle opening filled the room first, soon followed by a squelch
and a quiet grunt from Dean as he lubed up his cock. Sam, though he didn't dare
move his head to look at his brother, squirmed at the thought of what he was
doing. A quiet groan left Sam's lips as his legs were spread and pushed towards
his chest, though he moved his hands up to hold them there, anticipating Dean's
next move. He almost squeaked when he felt Dean against his entrance, barely
pressing against it but somehow still driving Sam wild.
"Dean, oh," Sam let out a quiet groan, feeling the head of Dean's cock press
into him. With a push of his hips, Dean slid into him half-way, slowly and
careful even though the whole ordeal was anything but. "Yes," though Dean was
only halfway inside of Sam, he felt so full, so amazing.
When Dean began to move inside of Sam, it felt as if the entire world around
the two of them tranformed into a blur, completely useless to them. Wave after
wave of pleasure rushed through his veins as Dean found his spot, rutting
against it with nearly everything he had, moving his hips in the least delicate
way, and forcing the bed underneath the two of them to move with him.
Sam's panting came to a halt, catching in the back of his throat and turning
into a string of moans as a sense of overwhelming pleasure rushed through him.
He could feel Dean's fingers wrap around his cock, stroking him off-rhythm with
his thrusts, and could hear the sound of their skin slapping together. As Dean
continued to pound into him, his back arched off the bed, something close to a
scream escaping his lips as he felt himself on the brink of orgasm- already.
A sense of pure pleasure rushed through Sam's body as hot come shot from his
cock, onto his own stomach. His entire body twitched as he rode out his orgasm,
feeling Dean's cum spilling inside of him somewhere along the way.
Sam's heart pounded in his chest as he felt Dean's arms wrap around him. His
eyelids felt as if they weighed a thousand pounds and his entire body was limp,
but he was in a pure bliss as he fell asleep, his face against Dean's chest.
It seemed as if the two of them had completely forgotten about the porn site
that was open on their father's computer.
