Summary
     Puberty hits Sam hard
Notes
     Just porn, no explanation necessary.
The first time it happened it really was an accident. Sam had been having a
good dream and must have rolled over into Dean during the night. Without
warning, the dream went from good to downright awesome. He woke suddenly,
gasping slightly with pleasure, wondering why the front of his pyjamas were
warm and wet.
“Sammy?” came a sleepy question from Dean, waking slightly to look at his
little brother.
“Sorry I-I don't...” Sam's face burned as he looked down at his pelvis pressed
against Dean's hip. He pushed himself away slightly. “What-” Sam choked back a
cry.
“'S'ok Sammy. You had a wet dream. Go clean up and change your pants.” Dean's
voice was tender.
Sam just looked at Dean for a moment, not knowing what to ask.
That's when Dean remembered how they hadn't stayed in one place long enough for
Sam to have the sex ed classes in school. And really, Dean had hit puberty a
little late for his age, but Sam was early so Dad probably hadn't thought of
having 'the talk' yet. “Do you know what a wet dream is?” Dean asked quietly so
as not to wake their dad. Sam shook his head, pulling away from Dean and
plucking at the front of his pants. Dean took a breath to try to sort out his
sleepy thoughts. “You know what puberty is?” Again Sam shook his head. “Ok, you
notice any new hair on you?”
Sam had noticed the supreme itch of new hair growing between his legs. He was
going to ask dad or Dean about it but didn't know how to bring it up. “Yeah,”
he said quietly.
“Yeah,” Dean repeated. “Armpits, between your legs, thicker on your legs, chest
maybe. Freaking everywhere.” Dean felt Sam sag with relief beside him. “You
notice how grown men look different than children?” Sam nodded. “Puberty
changes your body so you will look like a man too. And have wet dreams. Your
balls are making spunk now. Be careful because you can get a girl pregnant with
it. I'll explain that later.” Dean paused to assess his brother. He looked less
freaked out, so that was good. “You ever...touch your..” Dean waved to Sam's
crotch.
Sam nodded shyly. He liked touching it. A lot. Every chance he could get. He
noticed that Dad and Dean didn't touch themselves so Sam had tried to keep it
secret. Under the blankets in the back seat, or at night when he fell asleep,
or in the mornings when he was awake first. Realization dawned on Sam, Dean
touched himself too. All those times the bed they shared would shake oddly at
night. Sam always thought Dean was having a nightmare with his heavy breathing,
but no, Dean liked it too.
“Now when you jerk off you'll come like you did in your wet dream.”
Sam shifted slightly. He could feel it hard again. He desperately wanted to put
his hands in his pants but Dean kept looking. So he just pressed his palm on
the outside a little. “Ok. Dean...do you...how do....” Sam paused, partly to
make sure he wasn't moving too much or breathing too hard.
“How do I what Sammy? You can ask anything, I won't laugh.” Dean was trying
very hard not to notice the tiny hip motions of his brother beside him. He
already had a hand splayed out on top of his erection so it wouldn't tent in
the sheets. The problem was that it was starting to feel really good...and
wrong. Sam was his brother.
Sam took a deep breath. “How do I make sure I don't make a mess,” he rushed,
squeezing himself slightly.
Dean pressed down on his own problem when he heard a tiny gasp at the end of
Sam's sentence. “You will always make a mess when you come. That's the way it
is. You can't help the wet dreams, but if you jerk off in the shower or
bathroom it's easier to clean up.” Dean bit his lip hard to avoid moaning as
his hand started rhythmically pushing down on himself.
The snoring suddenly stopped from the next bed. Sam and Dean both froze until
the snoring resumed.
Sam felt such relief that Dad hadn't woken up that he allowed himself a sigh of
pleasure. “So...it's ok to touch it?” he asked in a breathy voice, moving his
leg so he could cup his balls.
Sam's voice almost did Dean in. He lifted the knee closest to Sam so he could
get his hand in his pants without Sam noticing. The feeling of his palm on his
bare cock made him moan. He cleared his throat to cover the sound, sneaking a
look at Sam. Dean felt his cock harden impossibly at the sight. Sam's eyes were
closed, his breathing slightly ragged, his arm moving in time with his narrow
hips. “Yes,” Dean hoped Sam couldn't hear the gasp in his voice. “It's normal
to touch it, and it's normal to feel good.” Dean couldn't help what his hand
was doing. Sliding around his balls, cupping them, forcing his shaft through
his fist, gathering the precome from the tip, slicking it down as far as he
could before sliding his hand back up.
Sam wanted to stop. He did. But his hand had a mind of its own. While Dean was
talking Sam got his hand down his pants and was bucking his hips into his palm.
The wetness of the dream made his cock slip around on his hand in a way Sam
never knew could feel so good. He wanted this feeling to last forever, every
nerve singing with pleasure, his cock begging him to move faster and faster.
Sam stopped trying to hide it, he couldn't remember why he was trying to be
secret, it felt too amazingly good to stop. Suddenly it was the best feeling in
the entire world. A gasp punched out of him as he splashed on his palm, body
going rigid for a second.
Oh my god he came, was all Dean could think. Barely able to control his voice
he told Sam to go to the bathroom and clean up. Please hurry, go, please go, he
thought. The second Sam was out of bed and heading to the washroom Dean flailed
around on the floor beside the bed, grabbing the first shirt he laid his hand
on. The door barely snicked shut when Dean flung the covers off, shoved his
pants down, covered himself with his shirt, and jerked furiously. It didn't
take long for him to shoot into the shirt, hard. He wanted to stroke himself
slowly to come down but he knew there was no time. Instead he stroked as much
of the orgasm out of himself as he could, cleaned up any splatters with the
shirt, and had himself put back together mere seconds before Sam returned to
bed.

The second time was not an accident. Not at all. Sam was horny. Hornier than
he'd ever been in all of his years on the planet. The weather was hot and muggy
lately so Dean had been walking around in just jeans or jeans and an
undershirt. Sam couldn't help but let his eyes roam around Dean's body,
watching his muscles bunching. Today was the kicker. Dean and Dad were doing
some basic maintenance to the Impala before they all head home. There was Dean,
tanned and sweaty, slightly dirty from engine grease and dust that the wind
kept kicking up. Even his short hair looked mussed up, Sam kept pretending it
was his long fingers that gripped Dean's short hair, making it look the way it
did. It took everything Sam had not to grind his pelvis against every surface
he could find. He knew he should go to the bathroom and touch himself...but he
didn't want to give up the tingling sensations between his legs. He wanted it
to last as long as possible.
Dean knew that Sam was watching, and he was absolutely certain that there is a
reservation in Hell for him as he preened for his little brother. The way he
bent over on purpose for Sam, the way he tensed his abs so his baby brother
could see how cut he was, the way his arms worked as he tinkered with the car,
all of these moments and more were going to pave the way to his special corner
table in Hell.
Sam was practically jumping out of his skin when their dad announced he was
going to the bar that night. It took forever for Dad to shower and get dressed.
While Dad was in the shower Sam let himself go while watching Dean move around
the motel room. He cupped himself through his jeans as Dean put his tools away.
He bucked into his palm as Dean washed his hands in the kitchenette sink. He
squeezed his own bulge when Dean bent over to take off his boots and socks. By
the time Dad was done his shower Sam was flushed and restless, hiding his boner
with a school book while sitting upright on the bed. Sam heard Dad telling Dean
to watch him, make sure he was safe and to not wait up. Dean nodded throughout
the speech, peppering 'yes sir' when needed. Sam couldn't rip his eyes away
from the bulge in Dean's pants.
Neither of them spoke until they'd counted to sixty after the last sound of the
Impala's tires. In the meantime Sam let his hand creep down between his legs,
outlining his erection, staring Dean down the whole time.
“Sammy,” Dean croaked. He knew his next words should be stop, no, we're
brothers, don't, wrong. Instead “come here” fell out of his mouth.
Sam whimpered, unsure if he could walk. All the blood in his body was currently
in the iron rod in his pants. “Dean,” he breathed. Unable to stop, he plunged a
hand into his jeans, trying to stroke slowly and drag it out. He was lost as
soon as he saw Dean unbuttoned his own jeans. Dean standing there all sweaty
and dirty with his pants open made Sam slam his hips up and release the orgasm
he'd been chasing all day.
Dean was mesmerized by the sight of his brother coming. God, how his eyes shone
with lust, his face flushing and lax, his lithe body writhing on the bed with
want. He made the prettiest sound when the dark spot appeared on the front of
his pants. Knowing Sam could get it up pretty much right away fuelled Dean's
walk to the bed. “Sammy,” he managed, pressing his palm on the bulge in his
pants. He'd spent the day without underwear, relishing in every drag of the
fabric on his cock.
“Oh...Dean,” Sam whined. “Wanna see you come. Wanna see you. Dean. Let me see
it. I wanna see.” Sam whimpered, already thrusting into his sticky pants, his
hand working furiously trapped in the denim. Sam had spread his legs out and
was using his bare heels as anchors to force his hips up. Dean could see the
lump of his hand through the jeans moving down, behind his balls, and back up
on his shaft. “Please Dean, please,” Sam begged.
Desire overrode Dean's brain. “You wanna see? I saw you looking at me all day,”
Dean pushed his pants down slightly, his cock springing up when freed. Sam made
sinfully dirty noises at the sight of Dean wrapping his hand around his cock.
“You wanna touch it? You wanna make your brother feel good?” Dean watched as
Sam arched up on the bed, crying out while staring at Dean's now weeping cock.
“You coming little brother? You come in your pants? Dirty dirty baby brother,”
Dean chanted, not having any idea where these thoughts were coming from.
Sam was electrified. Fresh come leaking through his fingers he panted loudly.
“Dean, you're so big! I can make you feel good...I can, let me try, Dean let me
touch it!” Sam was not even aware that he'd started rutting into his hand
again. Slippery and sticky at the same time his fingers roamed all over his
privates. “Take my pants off Dean, take them off so I don't have to stop,” Sam
begged, rolling his hips in Dean's direction.
Dean thrust his own pants down all the way, ripped off his top, and was on the
bed in a flash. He grabbed Sam's pants and yanked hard, tearing them from his
body while Sam whimpered and writhed beneath him. He took a second to watch his
brother's hand moving in the soaked boxers before groaning loudly and whipping
them off. Dean barely registered grabbing Sam's shirt and getting it off his
skinny chest. Dean paused there, bracing himself on the headboard behind Sam,
straddling him without touching him.
As soon as Sam saw they were both naked he looked at Dean's face, watching as
Dean's features soften when Sam let his wet pink tongue drag across his lips.
He left his mouth hanging open slightly, noticing how his big brother couldn't
take his eyes off Sam's parted lips. “You want me to kiss it?” Sam asked
softly, stroking come on himself, bucking gently.
Dean just about blew his load at that. “Sammy,” he tried. Dean felt a drop of
precome ooze out and drip down, landing on his little brother. Sam took that as
an invitation and shimmied himself down on the bed between his big brother's
legs. He stopped when his face was inches from Dean's cock. “Sammy,” Dean tried
again.
“So big,” Sam moaned just as he placed his pursed lips on the tip of Dean's
cock. Dean let out a guttural cry at the sight of his pretty little brother's
lips slip-sliding all over the crown of his dick. Sam didn't stop there, he
dragged his lips all around Dean's shaft, tasting him, feeling him, fluttering
his eyes and moaning the whole time.
“Sammy!” Dean yelled. He was way too close. Out of nowhere he felt his
brother's slim fingers slide up and grip his trembling thighs. One hand was
still slick with his spunk, that's the hand that dragged up Dean's thigh until
it met the base of his throbbing cock. “Sammy!” he screamed.
Sam could not get enough of the feeling of Dean over top of him like that –
straining hard to keep from thrusting too hard. He wanted to keep this feeling,
making his tough big brother beg and scream his name. But he also desperately
wanted more friction. “Dean...wanna rub myself on you...let me do it, please,
let me rub on you, Dean, please,” Sam begged around licks to his brother's
cock. Sam pulled away and gave Dean a little push.
Dean immediately flipped himself onto his back. “Sammy, Sam, come here, get on
me, Sam now, Sammy,” Dean babbled, rutting his hips into the air. Sam obliged.
He bounded up and landed on top of Dean, his come slicked cock pressing down on
Dean's spit slicked rod. Sam slid his legs down so he was laying prone on top
of his big, sweaty, still dirty brother.
“Oh Dean, wanna have you touch me all the time,” Sam writhed around on Dean.
“Want you to touch me at night, want your big hands on my cock, want you to
make me come, thinking of you all day,” Sam dragged his hips down, changing the
pace just before Dean burst. “All day, watching you, I wanted to rub on you,”
Sam stopped to stutter his hips as Dean thrust up. “You feel...so....good,” Sam
breathed.
Dean was losing his mind. His little brother was doing things with his hips he
didn't know were possible. Dean reached up and grabbed Sam's ass eliciting a
cry that made Dean's balls curl up tight against him.
“Gonna come again Dean, gonna come on you, can't wait,” Sam grabbed at Dean's
shoulders, pushing himself up as he let his orgasm take over. The sight of
Sam's cock pulsing drove Dean over the edge. Grinding his brother's slim hips
down on himself he finally let himself explode all over them. Rope after rope
painted their chests as Dean writhed and moaned his brother's name. Sam
suddenly moved his legs to straddle Dean while thrusting his hips forward then
back, forcing Dean's cock to slide in between his baby brother's cheeks, the
last of his come slicking his crack. “Oh Deeeaan,” Sam groaned, fucking his
brother's cock over his sensitive hole.
Dean did not know it was possible for him to stay hard. Breathing heavily he
let Sam masturbate on the tip of his cock. No way was he going to gain entry,
he'd be way too tight, but goddamn the way Sam swirled his opening on Dean's
cock was downright amazing. Looking at his fucked out little brother covered in
come rotating his hips made Dean insane with lust. He let out a long, low whine
as Sam's puckered hole pushed on his sensitive cock.
“Touch me Dean, touch me please, make me come Dean,” Sam begged, head lolling
side to side while he tried to force his hips down on Dean.
How is he even still hard, Dean marvelled. He watched Sam's face collapse in
ecstasy as he closed his fist around Sam's cock. Not believing it was possible,
he was sure he felt Sam's hole open just a tiny bit. It took a tremendous force
of will not to thrust up into his brother. Grunting with the knowledge that he
was a twisted person for doing any of this, he scooped up some come with his
free hand. He lifted himself slightly to reach behind Sam where he smeared the
come on as much of his cock and Sam's ass as he could before falling back
again, grabbing the sheet to stop himself from forcing Sam's hips down. The
sliding sensation was making him see stars. Each time Sam rolled his hips it
was like he was opening himself up just a tiny bit more. Whenever Dean could
remember he stroked his brother's ridiculously hard cock.
“Dean,” Sam whispered, “do you think we can get it in? Can we?” Sam thrust his
hips down harder. “I want you in me, want to feel your come drip out of me, can
we do it?” Sam was intent on grinding, getting a little more forceful with
every rotation of his hips. “Feels so good, Dean you feel so good, so big,
hhhnnngg,want you,” Sam moaned.
Dean could feel Sam's cock growing harder in his hand. “Sam, I won't fit, Sam
don't wanna hurt you,” Dean panted. God he wanted it though. He desperately
wanted to be gripped tight by his brother's ass. It wasn't even a thought in
his head ten minutes ago and now it was the single and only thing he wanted out
of life. What he couldn't believe was that his brother wanted it too.
“I can feel it already, getting you in, just gotta relax more,” Sam let his
eyes fall on Dean's. “Kiss me,” he demanded breathlessly, cheeks flushed, eyes
shining, messy hair falling around his face, lips open and wet.
Dean didn't hesitate when Sam bent down for his kiss. It was clumsy and messy
and sloppy and inexperienced and the hottest kiss Dean had ever received.
Dean's hand worked furiously between them, stroking Sam as best he could. The
sounds coming from Sam were nothing short of filthy. Those sinful noises
ignited the bonfire inside Dean's pelvis, driving his orgasm to the point of no
return. “Coming...Sammy....co-” was all he managed to say against Sam's mouth
while he tried not to thrust too hard up into his little brother.
Sam kept chanting, “in me, in me, in me,” while he positioned himself so the
tip of Dean was breaching Sam's tight ring before Dean's orgasm began. Dean
barely had the presence of mind to stop himself from seriously hurting his
young brother as he shot his load.
“Oh Deeeaaan,” Sammy moaned, his whole crack dripping with come. Dean felt
Sam's impossible fourth orgasm pulse through his hand, splashing onto his belly
between them.
Dean let Sam ride his cock until he was too sensitive. If Sam kept going this
way he was going to get Dean hard again, but Dean knew from experience that it
would hurt too much. “Ok, enough, enough, stop,” Dean pleaded breathlessly.
“Dean?” came a small voice above him. Dean didn't know he had his eyes closed
until he opened them to see a worried, dishevelled brother above him.
“'S'ok, just too tender, gotta stop for now.” Dean used the remainder of his
strength to pull Sam down on top of him, kissing him slowly when his face was
close. “You ok? Did I hurt you?” Dean asked in between kisses.
“No not hurt. So good. Tired.” Sam's mouth was getting lazy on Dean's. He
pulled away and snuggled his head into Dean's neck, letting his full weight
rest on Dean's body.
“Oh no, not sleeping, we have to shower.” When Sam made no move to get up Dean
changed reasoning. “Do you want Dad to see this?”
Sam grunted but moved. Dean led him to the shower where he took the opportunity
to slide his hands all over his slim brother. The soapy water coursing down Sam
made Dean's cock twitch with interest, but he ignored it. Once they were clean
and dry Dean tucked them both into the bed, letting Sam curl up against his
side. “We can't do anything in front of Dad,” Dean murmured into Sam's damp
hair.
“Mmmmmkay,” Sam agreed.
“Hey Sammy...” Dean's voice tentative, “where'd you learn to do those things?”
“Porn channel you watched yesterday...pretended to be sleeping while you
touched yourself,” Sam mumbled just before his breathing deepened into sleep.
Yep. Hell. I'm going to Hell, was Dean's final thought before letting sleep
claim him.
