Summary
     Sam is a tease, dean never stood a chance.
Notes
     Sam is 15! Dean 19!
***** Chapter 1 *****
It's hard to pin point the exact moment when Dean's feelings toward his brother
turned and twisted into something other than brotherly. In his defense, Sam's
like a walking and talking wet dream. Miles of tanned skin just begging to be
marked up, long shaggy chestnut hair that's almost always falling in his eyes,
broad shoulders and god! don't even get him started on Sam's stomach. His abs
are just starting to form but Dean can already see the potential there. His
slender waist just begging for Dean's hands, for his mouth, for his tongue.
Okay so, maybe he's got it really bad for his kid brother but damn, like he
said, walking and talking wet dream.
It's so much more than that though. Sam is, well, he's Dean's everything. He's
so damn smart, and he's all heart, that kid. Always understanding and
compassionate. He's gonna save the world one day with all that love, Dean's
sure of it. From the moment their dad placed his tiny body in Dean's arms he
knew without a doubt that no one would ever come close to meaning what Sam
meant to him. That someone had carved a Sam size hole inside his heart leaving
no room for anyone or anything else. It was just that simple.
Somewhere along the way the lines got blurred. Blurred enough that they
stumbled over them and into each other's arms. The next morning brought with it
guilt that ate at Dean's conscience like a hungry cancer and words of "never
again Sammy," that shattered his little brother's heart. But Little brother's
with broken hearts are dangerous. They put on a show by licking their sticky,
ice-cream covered fingers. Their gaze never leaving yours because of course
you're watching, dick painfully hard in your pants, finger's aching to grab and
show him exactly what he should be sucking on. You try to be good, to do the
right thing but Sam's not playing fair.
So yeah, If Dean's being honest with himself, he would admit that this is all
his fault. That he's successfully and single handedly created a monster, one
who looks at him with innocent kaleidoscope eyes but let's be clear... There's
nothing innocent about his 15 year old brother. He's gonna be Dean's undoing.
Destroy him in the most beautiful way possible.
They're stuck in the impala headed towards Grand Haven Michigan with their dad
snoring loudly in the passenger seat and his brother moping in the back. Dean
hates to see Sam unhappy but damn, at least this way he'll get a small break.
It's getting harder to ignore, those reasons he tells himself why it's wrong no
longer sounding as logical. His resolve is wearing dangerously thin.
Little brother's are also sneaky and brave and there's no way Dean could have
prepared himself for the living, breathing temptation all but fondling himself
in the back seat. Those long fingers rubbing over his basketball shorts to
tease his hard prick that's now clearly outlined and dean can't help but glance
into the rear view mirror to sneak a peak. He's breathing hard trying to ignore
his own swollen member now pressing painfully against his zipper and he turns
the radio up to try and cover the half-broken little moans floating their way
up to the front seat.
Classic rock spills into the car, the lyrics a perfect soundtrack to this
perverted little peep show.
 
Burn out the day
Burn out the night
I can't see no reason
To put up a fight
I'm living for givin' the devil his due,
I'm burnin', I'm burnin', I'm burnin', for you
I'm burnin', I'm burnin', I'm burnin' for you!
 
There's a light sheen of sweat on Dean's forehead and he licks his lips and
peeks at his father still asleep and thankfully oblivious to what's going on.
His fucking heart is hammering inside his chest, throat dry and knuckles white
from the death grip he's got on the steering wheel.
Sam arches his back hands flirting with the waistband of his shorts. Slowly,
pulling them down until his dick pops free and slaps angrily against his
stomach smearing pre-come that's now dripping from the tip.
Dean swallows hard against the knot in his throat, tries not to whine because
Goddamn! Sam's trying to kill him.
Sam's hand has a deadly rhythm going, striping his dick fast, endgame in sight.
Dean sucks in a breath because he knows what's coming. And he tries to swallow
down the growl trying to crawl it's way up his throat as Sam shoots his load,
wet and oozing down his fingers.
"Dean", he hears a familiar voice say pulling his attention to the gruff and
grouchy man staring at him questioningly in the passenger seat.
" You wanna explain to me why you're doing 90 in a 70 mph zone? You got a fire
in your pants or something boy?"
"I - uh," he stammers glancing one more quick peek at his brother that's now
wrapped in a blanket, head laying against the window, "sound asleep". That
little shit!
" Sorry sir," he continues. "I'm just getting tired and there's no body else
out. Haven't passed another car in 20 miles. "
"You only got another 20 or 30 minutes till we get there son. You think you can
handle that?" His dad asks
"Yes sir" he replies and keeps his eyes on the road.
He's done with these games. If Sam wants it then that's exactly what he's gonna
get. Big brothers are dangerous too.
***** All of my love *****
Chapter Summary
     Sam has been naughty and it's Dean's turn to teach him a lesson.
     *sorry, I suck at summary's.
They stand in the gravel lot, nothing but silence between them, as they watch
the impala's tail lights disappear into the night. Dean turns to look at his
brother, trying hard not to get lost in how beautiful he looks in the pale
moonlight. He clears his throat and prays his voice won't betray how much of a
mess he is right now.
"I'm gonna give you twenty minutes to unpack and salt all the windows and doors
then we're gonna have a talk."
His brother looks up from under his shaggy bangs.
"About what?" He asks
"About us." Dean replies motioning his hand between the two of them.
"Us?" He answers, "what-um, what about us?"
"Twenty minutes Sammy." He says again as he walks away leaving his brother
standing there twisting the toe of one sneaker nervously into the dust.
When he gets out of the shower Sam's waiting for him on the couch, but he
stands quickly and takes a tentative step towards Dean.
"Look, I- I'm," but the rest of his words get stuck in his throat when he
realizes that Dean is standing there practically naked, except for the thin,
threadbare towel that's hanging dangerously low across his hips, little drops
of water still dripping from his body and now it's Sam's turn to suppress his
want, his need.
"I'm done playing games Sammy," Dean says getting straight to the point.
"So if this is what you really want, there's gonna be rules. You understand?"
But he doesn't give Sam time to answer. "This IS what you want right?" He asks
and his voice is taunting and rough and he can't help but notice the small
shiver his words invoke on his brother.
Sam's mouth has gone desert-dry all of a sudden but he nods his head, unable to
speak, unable to take his eyes off of his sex-god of a brother, and he's really
wishing that he would have stayed sitting because he's fairly certain
astronauts from space could see how hard he is right now.
"So, um rules?" He asks finally finding his voice.
"Just one really." Dean says and he's pretty proud of how steady his voice is,
impressed by how completely disheveled his brother is already and they haven't
even gotten to the good stuff yet.
"If we do this, we have to be careful. No more stunts like you pulled in the
car. You understand?" Sam nods so Dean continues.
"Speaking of that, there will be punishment." He says, taking a small step
towards Sam.
"What kind of punishment?" Sam asks, wet and leaking into this boxers at just
the promise of his big brother's words.
"You can't touch yourself and you can't come until I give you permission." Dean
says, a wicked smile playing at the corners of his mouth. He's gonna enjoy
this.
"Ok," Sam says, and he can't help the blush that rises on his cheeks and
spreads like wildfire, and he's surprised that he has any blood left to
circulate.
"So, you wanna go to the bedroom?" Sam suggest, more than ready to get this
thing started.
We'll make our way there." Dean smiles. "But first you're gonna suck me off.
Right here."
And he loosens his hold on the towel and let's it fall to the floor. Sam falls
to his knees and practically crawls to Dean, mouth no longer dry, tongue
dancing behind his lips cause he's dying to get a taste.
He kitten-licks the tip of his big brother's cock and circles his tongue around
the ruddy head before he closes his lips around him and sucks. Dean runs one
hand through his brothers chestnut hair and slightly rolls his hips forward,
just enough to make Sam gag a little, then pulls him off, and back down again.
Sam might be new at this but he's a quick study. It's sloppy, Sam's spit
running down his balls and trickling down his legs but Jesus Christ! It's the
best damn blowjob Dean's ever had.
His little brother is still gagging on his cock and tears are collecting at the
corners of Sam's eyes as he stares up at him, but he's taking it like a fucking
champ and Dean is so close to losing it his legs are starting to shake. When he
comes hot and salty down his brother's throat, he nearly blacks out from the
sheer intensity of it. Sam moans as he swallows him down, not spilling a single
drop.
It takes Dean a minute to gain his composure before he leans over and kisses
his brother, licking into his mouth, tasting the remnants of himself on Sam's
tongue. It's not a tender kiss, more of a brutish brushing of lips, a bruising
and aching need to close the small distance between them. It's hungry and both
of them are starving.
"Bedroom now!" Dean all but growls and Sam doesn't waste any time following
suit, still aching and dripping in his pants.
Dean runs his callused hands across the smooth, round globes of Sam's pert ass
cheeks spreading him open and licks a stripe across his hole. Sam's back arches
and he can't help but push back against Dean's tongue as he dips inside to
steal another taste.
He gets him good and wet, pushing his tongue inside as far as it will go before
adding a finger and works on opening him up. His little brother is squirming as
a second finger joins the first one, sinking past the first ring of muscle.
"Fuck Dean, please." He begs after a few minutes, hands grabbing at the sheets,
but Dean just smiles, no way is he letting Sam off that easy.
A third finger joins the other two and Dean scissors them, stretching his
brother's tight hole to make room for him. Sam sounds like he's crying, he's
grinding back against Dean's hand, trying his best to get it deeper, trying to
reach that sweet spot inside him and when he finally brushes it the moan that
leaves Sam's throat sends a chill down Dean's spine that has him scrambling for
the lube he keeps tucked away inside his bag.
He coats his dick and pushes inside the tight, wet heat of his brother's ass
not stopping until he's buried all the way inside. He gives Sam a moment to
adjust to the feeling of being so full before he slides out and thrust back in.
It doesn't take long before his hips have worked up a good rhythm, slamming
inside and back out only to plunge in again, each time desperately trying to
get deeper even though there's no more room , the slick-slap sound of their
bodies smacking together and the sound of their labored breaths a soundtrack of
their sin. Its so dirty and wrong but in that way that's so damn right it
hurts. Dean never wants be anywhere else, wants to live inside the tight, hot
space Sam's created for him forever.
His hands dig their way into the sharp jut of Sam's hipbones as he fucks his
brother at a punishing pace and Sam's clawing at the mattress, the sheet now
hanging halfway off the bed, the headboard banging loud against the wall and
it's a damn good thing they don't have any neighbors.
"Dean fuck, please. I wanna come, oh god! Let me come." His brother cries out.
And dean could really get used to the sound of his brother begging.
He's nailing Sam's prostate at almost every thrust now and the filthy moans
that fill the room are only fueling his desire to keep going but he can feel
the start of his orgasm building at the base of his spine.
"Yeah, you wanna come Sammy?" He pants. You want big brother to fill you full?"
"Yes! Please Dean. Please!" He begs again so Dean takes pity on him, slides one
hand down between his brother's legs and wraps his hand around Sam's hard
length. It doesn't take many strokes before Sam's seizing up, his hole clamping
down on Dean's dick, coming hard, Dean spilling his seed not a few seconds
later.
They both collapse on the bed, sweaty and sated, their breathing still a little
erratic but their spines tingling with post-orgasm bliss.
Sam's quiet for a minute, trying to work up enough spit in his mouth to even be
able to talk but he let's out a broken sob in the form of his brother is name.
Dean is right there, his arms wrapping around his brother, pulling him close.
"What's wrong Sammy? Did I hurt you?" He asks
"No," Sam assures him. "You didn't hurt me Dean. I was just thinking that, well
what if you freak out about this and decide you don't want me again?"
Dean tries hard to fight against the tears that are threatening to break free
and pulls Sam even closer so that his head is laying against his chest, right
over his heart; over Sam's home.
"It was never an issue of not wanting you Sammy." Just had to get past the
dirty, bad, wrong that my conscience keep screaming at me."
"There'll never come a day that I won't want you ok?" He promises.
"I love you Sam."
"Promise?" He hears his brother whisper, his hot breath washing across his a
still overheated skin.
"Promise." Dean whispers and places a soft kiss to Sam's forehead.
"Hey Dean?," Sam sighs, "sleep now threatening to claim him.
"Yeah Sammy? He asks
" I love you too." He says and Dean's smile is so big in that moment it could
light up the night.
Yeah, Little brother's are most definitely dangerous, and brave but their also
light and love, a brilliantly beautiful cacophony of adoration and devotion.
The only thing that makes this horrible life worth living, each breath worth
taking. Little brother's are forever.
