Summary
     Sam's wanted to fuck his big brother for the longest goddamned time;
     just before he turns fifteen, he finally gets there and things move
     pretty fast.
 
"What was her name?" Dean is still whispering though his brother has long ago
given up on quieting himself.
"I don't even   know   it just sort of happened." Sam's slim frame bounces
lightly on their cot, so excited about his first groping session at school that
day that Dean is having a hard time controlling him; they're supposed to be
hiding, tucked into a nearly secret room in the back of one of their father's
safe houses. Their dad is out front on the ancient, worm eaten porch in a
sentinel silence with a shotgun cocked over his arm. Dean's on Sam duty,
sitting beside his fourteen year old brother on a cot barely big enough for two
that's been jammed into the space of a large closet.
"It was  so  awesome, Dean." Sam beams, distracted in memory, but Dean
concentrates on the vampires his father fears are after their already
diminished family. "I don't want to wait for more." Sam adds, leaning heavily
into Dean's left side. When Dean stiffens his back, closing off his body
language, Sam sighs but remains shoved against him.
"I'm sure it won't be long, you're only fourteen anyway." Sam snorts in
answering frustration, kicking one of his legs restlessly against the wall
until Dean stops him with a touch to his knee.
"Few days to fifteen--I'm ready."
He probably is, but Dean isn't going to dwell on that thought.
Dean may be insensitive but he sure as hell hasn't missed the fact that Sam
wants to have sex with him. He's been trying for over a year in ways that are
growing so crafty and intelligent that Dean's already out of his league and Sam
is getting sharper daily; it's terrifying.
They   are   brothers and that should probably make him feel a   lot  more
wrong about this than he does but he won't dwell on that, either. After all, he
and Sam have something altogether different than your average family so why
should this new dilemma break pattern?
Sam is tense on the bed, Dean suddenly realizes, watching him with an eye that
leaves little behind for the imagination. He's reckless with it, staring
brazenly at Dean in what used to be adoration but over the last six or so
months has turned truly hungry. When Dean glances away first his blurry
periferal vision notes Sam's cocksure smirk.
After a long beat Sam asks, "Dean, can we have some whiskey?" Probably not a
good idea but he'd love to get some actual sleep tonight.
"Sure." Ok, so he gives Sam drinks here and there, big deal. It's only a shot
and usually he falls asleep before he's done nursing it. Dean busies his damp
hands with the small glasses he keeps tucked into his backpack, lining them up
and pouring two shots out carefully. "Then bed." He adds, handing Sam his
drink. Sam plucks it from Dean's larger hand and downs half of it in a swallow.
Dean simply holds his and stares.
"Not tired." Sam answers flatly, as if he were the one deciding. "  Whoa  ." he
sighs a second later, already giggling at the booze warming him.
"Go slow, Sam." Dean warns, scooting nearer to Sam's side of the cot and
immediately regretting it. His brother's focus narrows as the mirth evaporates.
"Boring." Sam answers firmly as Dean grits his teeth and peeks sideways at him,
taking his shot down in one toss of his head. Yes, he knows how much Sam loves
to watch him do it and he can hardly bear to disapoint the kid. Welcome threads
of alcoholic heat slither through his chest as Sam sips his shot and Dean
stares a smoking hole in the floor trying to ignore his brother.
"I'm bored too, but dad said-" Sam shoves at his side and effectively quiets
Dean's mumbling, sucking down another gulp of whiskey before speaking.
"Shut up about our orders, dude." The alcohol is really hitting him, Dean would
be laughing but before he can try Sam puts his hot palm on Dean's mid-thigh
with all the certainty of a full grown man. It's decidedly unbrotherly but so
is the burgeoning erection Dean is trying desperately not to have. "We never
have   any   fun." Sam says, quietier now and nearly to himself as his hand
gently kneads Dean's leg. Well, that much is true. Dean nods and tries to look
away from Sam's grip on him; he fails.
"Let's get ready for bed." he quickly mutters, hoping he can distract Sam long
enough that he will forget tempting his older brother; Dean can't say no
forever and then it's straight to hell on the underage incest express.
When all of this started he was certain it was a phase. Sam idolized him and
was overly hormonal in his teens. But months went by and Sam's desire was now
only more clear to Dean; leering looks when he's just out of the shower,
lingering touches that go beyond their previously clear personal boundaries and
as of last month trying to cuddle into Dean whenever they were forced to share
a bed - which happens often. Half a year is a painfully long time for this kind
of temptation, he didn't view Sam sexually before this but now   everything
has changed and he's fifteen; Dean lost his virginity at the same age.
Straight to hell.
Sam's hand retreats from Dean's leg to remove his own t-shirt and jeans, never
looking away as Dean starts to undo his buttons. His fucking traitorous
eyeballs want to gape at the bulge in Sam's underwear so he keeps them glued to
his flannel as he shucks it and turns down their lantern. The shadows make it
much easier for him to smuggle his half hard dick out of his pants and hide it
under the blankets.
That's of course until Sam bumps his hip into it while rolling over, which
seems nothing remotely like an accident to Dean who can only grunt and pulse
harder still.
"Did you bring your gun to bed, Dean?" The little smartass is tipsy from the
whiskey, so he will simply ignore the teasing. Most nights it's just the press
of Sam's body into his while he thinks about mass murder to stave off caving in
but tonight he's more challenging and   maybe   Jim Beam wasn't a great
addition to horny Sam.
"  Sam  ." Dean warns when his brother shifts again, flipping onto his back.
"  Dean  ." he responds in kind, imitating his brother's deeper voice.
"  Please   just go to sleep." The moment it leaves his lips he knows his
desparate, strained tone gave too much away. Sam lays quiet and motionless,
which means his nimble mind is working and Dean doesn't commonly emerge on the
winning side of that.
"I don't think so." Sam answers at length, shuffling beneath the blanket in the
closely pressed dimness. "Not   yet  , anyway."
Dean's retort snags in his throat because even in this poor light and under
their blanket there can be no mistaking the ladder of his brother's fingers in
a slowly moving fist around his dick, Dean can just barely see it bobbing in
Sam's lap.
"Are you   serious  ?" he hisses, trying to sound more angry than he finds
himself. He hasn't been able to look away as Sam tugs and this is fast becoming
too much for him to resist, Sam sighs on half a gasp and Dean is nearly done in
right then.
"I think you know I am." Sam answers, his voice raspy with breath.
"Sam..." he'd find the words and strength to let Sam down quicker if he could
stop being so turned on; why is he so turned on? Because Sam is beautiful and
scary smart and everything he cares about, maybe. He keeps waiting to feel more
perverse about indulging them both but the more thought he gives it the more he
does not. Sam is young but quite mature and Dean is sure he's ready for sex but
he's also pretty emotionally intimidated by what this would mean to both of
them. He tries another tact. "We shouldn't--"
"You   want   to." Sam's voice is soft but no less definitive for it. "I knew
you wanted to before you did."
"...Even if that's true we shouldnt do it." Sam doesn't miss a beat with his
stroking and for fuck's sakes he can't stop watching; it's invalidating any
argument he's feebly attempting.
"Why not?" Sam's free hand regrips on Dean's thigh and squeezes. "Doesn't have
to change anything else about us." Or, you know,  everything  .
"There are   so many  reasons why not."
But none of them matter at all when Sam's palm sides up to the bottom of Dean's
balls and stays there, the index finger curiously turning circles though his
boxers. His cock lurches and he doesn't know who just made that pathetic noise
but he's not owning up to it. A question that's been stomping around his head
for months comes barging out.
"Why, Sam?"
The gentle motions on his skin become a hot grip as Sam tries to cup both of
Dean's balls in one hand, they don't quite fit and it's so  good  that Dean can
feel himself leaking. Sam is staring full at Dean's face but he can't even look
up.
"Just feels right," Sam smiles genuinely in the near darkness and adds, "has
for a long time." His fingers are gently kneading Dean's balls now and he just
wants to let his eyes roll back and moan but he fights manfully.
"But... I'll be taking your virginity." Dean can barely get the words out and
when he does Sam pushes his hips up to hump his own fist and lets a tiny groan
eek out. Clearly the idea is turning his brother on; Dean's own cock thumps
desperately in time with his pounding heart.
"I'm giving it to you, Dean. I've been trying to for like a   year  ." He
doesn't know how Sam finds his lips so perfectly but Dean doesn't get to make
his point about them regretting this later because he's busy kissing Sam and
suddenly realizes he could   never   regret   that.
"This is not a good idea." he blathers when they break for air only to press
together again, Sam's lips eagerly mashing into Dean's. It's clear even Dean
has stopped listening to himself as he pushes harder into Sam's mouth and
groans. Sam laughs back against him and slides his hand up, finally, to Dean's
hard on. They both breathe loudly, heads jammed into one another, before Sam
wraps his fingers and squeezes. "  Fuck  ." Dean swears through his teeth.
"God, you're  big,  Dean. I kinda knew but, wow." He's going to remember
hearing that compliment forever. Dean is fast losing any will to do the safe,
sane thing here and instead allows his lustful hands to finally decend on his
brother, down his side and over his ass, which is insanely smooth. "  Yeah  ,
Dean." Sam breathes out, his groping ignited by the break in Dean's self
control; in answer both of Sam's hands wrap Dean's cock after angrily yanking
his shorts down and regripping the bare skin.
"  Shit  , Sammy." He's used to Sam's heedless behavior but tonight he feels
something more intense than he's experienced from his brother before. Sam is
enthralled with jerking Dean off, concentrating fully on his steady tugs, so
Dean ignores the reasons he shouldn't and slides his hand from Sam's hip to cup
him through his underwear; his cock is hard as hell and longer than he
expected. Sam groans and thrusts instinctively into Dean's pressing hand. "  Oh
." Dean sighs out a desirous noise while rubbing the gentle curve of Sam's
dick; he can already tell it's as gorgeous as the rest of him.
"Thanks." Sam quips breathlessly, now drunk on whiskey   and   victory, god
help Dean. They separate for a few miserable seconds as they both kick off
their underwear and quickly re-collide. When Sam scoots closer to press them
together Dean gasps into his mouth, their searing cocks now slotted side by
side as their legs tangle. "You feel   amazing  ." Sam soothes as he grabs
Dean's hip and starts to rut against him, their leakings smearing together with
each push of his hips. Dean's hindbrain starts moving his body in time without
a thought and just like that he's having sex with his brother.
It really can't be that easy but it sure feels terrific to have Sam's hot,
tight body writhing into his and he hasn't been struck down yet.
"Your ass is so hot, Dean." Sam's hands knead and squeeze him roughly as he
pants. "I remember when I first noticed." Dean's body is overheated with lust
and he's had enough of dry humping and grabs right for Sam's cock; when he
pulls it Sam tips his head back up and his voice breaks on a moan.
"  Shhh  ." Dean hisses, slowing his stroke. "Not too loud."
"I can't help it, wanted you to touch me for   so long  ." Dean wishes he could
take back the strained noise he groans out at Sam's reminder and in answer Sam
quickly wraps both of his hands around Dean's hard on and tugs. "This good?"
"  Yeah  , Sammy. Fuckin' great." his whispered but honest words encourage his
brother and he arches his back when Sam thumbs the wet head of his cock. "
Shit.  " Dean swears again, thrusting himself at Sam's jerking hands. His own
fist works between Sam's legs and he can feel Sam's cock get even harder as he
speaks. After a few fumbles they get a rhythm going together and some making
out inbetween gasps and moans.
"God,   Dean  , slow down a little." Sam whines and Dean's past caring about
anyone's pride here; he wants to make Sam come in two minutes. His cock is
burning in Dean's hand and dribbling down his wrist but he jacks just a tiny
bit easier, gasping sharply when Sam rubs the underside of his cock again, both
hands still curled around Dean's twitching hard on.
"Ah,  fuck  , Sam."
"You sound   great  , Dean, but you just told   me   to be quiet." Sam warns,
jerking Dean too fast half a dozen times. Sam grunts as he works his hand and
Dean very nearly comes but instead smothers his face into his pillow and moans
too loudly.
"Whoa,   whoa   stop a second-" Dean fights Sam's double fisted grip but he
isn't letting go, only pausing for a few breathless moments and then diving
back in. His cock is flaring in Dean's hand so he's sure Sam is about to come
too.
"Don't wanna stop." Sam says roughly, pushing up on his elbow and rolling
himself over on top of Dean, who is in way too deep to deny Sam anything and
submits easily. "...That's what I thought." Sam smugly says of Dean's passive
move onto his back and Dean would start bitching but his nuts are ready to
burst and his brother is milking him fantastically. He's keeping pace with his
pulls over Sam's cock, now very near to his own as Sam kneels between Dean's
open thighs.
Dean has a sudden idea and wraps the hand jerking Sam around both of them,
rubbing their slick heads togther. They both moan and Sam squirts some precome
when Dean's free hand slips under to feel his balls.
"  Shit!   De,   yes  ." It's the only warning Dean gets before Sam shoots a
streak of hot come across his stomach, gasping and groaning as the following
pulses land in drops and globs on Dean. He wrings Sam's cock gently, his other
hand cupped around his nuts, until he comes back around enough to resume
tugging Dean again. "  Damn  ." Sam exhales in awe, speeding up and making Dean
moan. "I came so hard  all over  you."
That's more than Dean needs and after a handful of strokes he gasps loudly as
he's slammed by his own orgasm, rising out of him forcefully as Sam gapes down
watching; he quickly covers Dean's mouth as he shoots warm and sticky between
them. Thank goodness for his swift thinking because Dean is making   way   too
much noise into the meat of Sam's palm.
When Dean is done shaking and humping Sam's fists his brother lets go
reluctantly, turning to fall into the cot beside Dean, who lay heaving for
breath and bonelessly contemplating how coated in come and fucked up he is.
Giving in to his brother and his body felt far less wrong and harmful to Sam
than he might have previously considered it. He silently prays Sam doesn't feel
the need to talk about it and they can go directly to sleep after he cleans the
mess on himself with a discarded t shirt.
No such luck.
"Dean, this is..." Sam grabs for his hand in the darkness, it's still damp from
their come and when Dean chances a glance to his left Sam is licking his other
hand clean. Dean cannot react fast enough to stop a needy noise from sneaking
out and he knows he's blushing but Sam is sated and beaming - it's fucking
beautiful.
"We can talk later." Dean blocks, hoping they won't. They fall asleep jumbled
together, Sam refusing to allow Dean his hand back.
 
===============================================================================
 
They don't talk about it for a week, and by then when they finally get a
private moment they don't waste it with words but yanking dicks frantically in
the back of the Impala; their tongues down each other's throats. Dean has never
heard Sam say half of those swear words, it was so fucking hot he lasted about
three minutes; at least Sam was just as eager. Afterwards they flop loosely
into the front seat, heading home from yet another new first day of school for
Sam.
"  God  ," Sam pants, pushing his sweaty hair out of his mottled and color-
changing eyes, currently greenish. "That was   really   good." His left hand is
firm on Dean's right thigh as Dean wipes their come off, tucks himself away and
after starting the car maneuvers them back onto the pavement. Nothing like a
dirt road hook up but he can't fucking believe he just did it with his brother.
It's still such a new and shocking reality that it constantly startles Dean.
"I'm gunna do   so much  more with you." Sam says in a rush, preening his sex
rumpled clothing with exacting motions of his hands; watch the fucking road,
Dean.
"Like what?" Dean asks quietly a moment later, wishing he could at leastactless
desperate. Sam slides to his brother across the bench seat and sits up straight
to lean his mouth over Dean's ear.
"You're sleeping in   my   bed tonight." Sam states, quiet but decisive and he
just came like crazy yet his dick still flexes in his pants in excitement.
"Since we have our own room in this new motel." He's whispering right into
Dean's head and it's doing powerful things to him; Sam's left hand moves from
Dean's leg to the back of his neck, rubbing gently. "I can't   wait  to get my
dick in your pretty mouth."
"  Fuck  , Sam..." he won't deny he's been thinking about it a rather perverse
amount. That and about a hundred other things two guys can do together that
he's had only occasional reason to consider before now. He did   not   want to
ask Sam if he could suck his cock but somehow his brother knew to ask, well,
tell  Dean they're going to do it.
"Fuck,  what  ? Dean. You want to suck my cock or not?"
"  Yes  , yeah, I do." The words come tumbling out too much like begging and
not how he planned but it doesn't matter; one of Sam's hands is curled around
his neck and his other slides up Dean's thigh and stays there.
"Maybe I'll put my balls in there too." Fuck, how can the kid already talk like
this? Sam clearly knows this is working for Dean and if he doesn't stop he's
going to drive off the road; when he whines in desperation Sam pinches his
inner thigh   somewhat  gently.
"  Yeah  , Sammy." he sighs out, so happy to finally see the motel lights in
the distance; fresh blood rushes to his cock at the thought of the spending the
night submitting to Sam completely. "Whatever you want, just don't make me kill
us both on the way there."
Half an hour later both Sam and Dean are showered, Dean needed a cold one, and
anxiously waiting for their father to go out. While they do have their own room
his is adjacent and Dean is far too paranoid to touch Sam until he knows
they're alone or their dad is asleep.
Sam has no such scruples and so sits beside Dean on the bed whispering in his
ear, much as he was in the car, while Dean's cock finds new levels of hardness
to achieve inside the sweatpants he tugged on; arching in blatant want against
the soft fabric.
"Dude, your dick looks awesome; I wanna grab it." Sam huddles into Dean, hands
way too close to his hard on.
"Wait a minute, Sammy, dad is about to leave." Sam doesn't listen, hands
sliding up Dean's thigh as their father slams his door on the way out. Dean
jumps nervously but sighs in relief when he hears him pull out of the motel.
Sam is already rolling his balls in one authoritative hand.
"God, I've been dying to get you alone in a bed." he mutters, pushing Dean back
before pulling his own shirt and shorts off. Dean lies down and opens his legs
to watch his naked brother crawl up between his spread knees and dive onto him
with a firm kiss, tongue out from the start.
"Get these pants   off  ." Sam orders, helping Dean shove them down his legs.
"Mmm, damn your cock is   nice  ." Sam hums when Dean's hard, leaking dick
stands up and twitches. Dean can't help but touch it, wring it out with one
slow stroke that squeezes up another glob of precome. "Always so wet, I don't
leak as much." Sam grumbles, voice low with lust, licking his lips and panting.
Dean reaches up between them and fists Sam's hot, red dick; Sam's back arches
and he hisses.
"You're always sohard." Dean responds before groaning as Sam flexes his cock in
his grip. He's had his share of wondering curiosity about other men but he
never imagined he would want to suck a dick this much, so fucking bad that his
damn mouth is watering and he can't even wait. "Sam, roll over and lemme suck
it, please,I'm drooling here." He wipes his lips with the back of a hand to
punctuate.
"  Fuck  ." Sam swears, turning over quickly and thumbing his dick toward Dean.
"Open up." he tells him, threading his fingers into his hair to hold him as
Dean ducks to lay between his legs and slide the head of Sam's cock into his
mouth. "Oh, shit-  Dean  ."
It isn't too difficult to get past the salty bitterness, to fold his lips over
his teeth and then it's just the fleshy taste of his brother's pretty cock,
hard as hell and still a few years shy of full grown; the thought makes Dean
feel shame and sharp arousal at once and he moans, sinking halfway down Sam's
length easily. Sam cries out and humps up into him, pushing both his hands into
Dean's hair and gripping hard. After a few bobs of his head Dean realizes he
can fit all of Sam in his mouth if he uses his throat and he pushes his head
down until his nose touches Sam's belly; he gags but calms himself while his
brother swears in a stream of words above him.
"  Ohmygod  , Dean,   yes  ." Sam has enough impressive control to fuck Dean's
virginal mouth gently at first with slow, prodding thrusts, though it doesn't
stay that way long. When Dean starts moving faster than Sam's guiding hands Sam
grabs Dean's hair, regrips, and starts fucking him in earnest. "You want more,
huh?" he pants out, huffs turning to gasps as he bottoms out in Dean's throat
with each push; Dean can only moan.
"  Mmmph  ."
"Feels   so  good when you groan around it." Dean hums again in answer, one of
his groping hands palming both of Sam's balls. He cries out when Dean takes him
deep and keeps him there, bending at the waist to slide a hand up and down what
he can reach of Dean's back. "Do you like my cock in your throat, De?" Dean
moans again in answer; Sam thrusts and continues. "I'm gunna put it up your
ass, too." He isn't sure quite how he feels about   that   but it still makes
him hump the bed and gurgle against Sam's dick, he pulls back and licks at the
head while Sam stares hotly down at him.
"I don't know if I'd like that, Sammy." Dean answers honestly, without saying
he doesn't want to because he  kinda  does but he'd be lying if he didn't say
he's intimidated.
"I'll make sure you like it." Sam wipes his leaking cock on Dean's lips and
guides it back in, eyes rolling up when he gets the last inch stuffed in Dean's
burning mouth; Dean's cock throbs heavy and ready to blow just from sucking his
little brother and rubbing on the bed.
"  Fuck  , that feels  so good  , you want my come in your mouth?" Dean nods,
hums and slides up and down quickly with Sam's urging, sucking up the precome
dripping out of his brother as his own dick screams for attention against the
mattress. Sam's fists tighten painfully in his hair and Dean lets him use his
face how he needs, rubbing his own desperate cock against the growing wet spot
he's left on the covers.
When Sam's hips stutter and his dick surges in Dean's mouth he drops to swallow
him completely while he comes; a salty burn shot into the back of his throat.
Sam's wide open mouth cries loudy before his pulses slow to weak spurts and
Dean pulls back so he can taste them.
"  Fuck  , I thought I was gunna scream, that was the best thing I've   ever
felt." Dean soars with a sense of accomplishment before he pops the head of
Sam's cock out of his mouth and gets a full look at his scarlet red and
sweating face, his ridiculous hair now damp and clinging to him. "You're   good
at that, we're going to do it a lot." Dean turns and groans, droping his face
to Sam's inner thigh in an attempt to be bashful. "Lick my nuts and keep
jerking off." Sam lifts his still firm cock and pushes Dean's head down to rub
his face on his balls.
"Jesus, Sammy." he complains while none the less leaning in to lap at Sam's
sack; his head falls back and he sighs happily. "You don't normally order   me
around." Dean's statement is muffled by loose skin but Sam hears him, of
course.
"You don't normally   want  me to." He's watching Dean now, the same fire in
his eyes that Dean remembers from combat training; he's always loved seeing it
but didn't know why until this moment. Dean's been pulling his own dick
steadily but when Sam's leg drops its foot into Dean's lap he thrusts his hips
forward and speeds up. "But here..." Sam starts rubbing him wherever he can
reach with his surprisingly dexterous toes as he takes his own cock in hand and
jerks it towards the side of Dean's face. "Here you  like  to obey when I tell
you what to do, don't you? Makes you hard and needy."
His ego wants to take offense but it's such a relief to trust Sam with the
control he's always maintained; to see his brother as something other than a
child in need of protection. He stares up at him without pausing in his licking
or stroking and simply moans around his busy mouth, hoping lots of tongue will
suffice for everything he cannot verbalize.
"Yeah, I know you don't wanna admit it." Sam teases, banging his unceasingly
hard dick against the side of Dean's face. Dean grunts and licks up the base of
it; he already wants it back in his mouth. "But even if it wasn't already
obvious, I've been around you having sex before."
That never occured to him. Too many memories come suddenly flooding back; the
late nights he would sneak girls into his room, the things he asked for, the
noises and that one time he got a chick to spank him. He assumed Sam was asleep
but in hindsight that was rather stupid, who knows how much his brother heard.
Dean's blushing furiously but still working over his own dick and Sam's balls,
pausing to hold still when Sam wants to rub his dick on his face.
"I heard you doing all   sorts   of things, Dean." Sam angles his cock and
slides it back into Dean's mouth, they both moan and Dean is so thankful for
both the dick and the excuse not to talk. "I know a girl spanked you, did she
tie you up too? Because I saw rope the next day."
Well, so much for  that  secret, Dean sighs and nods around Sam's prick,
sucking it up and into his throat because he's already in love with the
feeling. "Oh,   fuck  , Dean. You're gunna get more come in your mouth soon."
The thought makes Dean's cock flex and leak, and when Sam gives a sharp thrust
deeper than he's been and bumps far back in his throat Dean explodes hot come
over his jerking fist, shocking both himself and Sam. Even with something in
his mouth he's loud, groaning around Sam's dick and finally resuming bobbing
his head when he gets his faculties back.
"Mmm, you shot all over my leg." Sam pants out, hand resting on the top of
Dean's head as he licks and sucks the length of him. Through his mind's
pleasure haze Dean remembers a blow job trick that's been done to him and
repeats it on Sam; holding the end of Sam's cock in his mouth against his
flattened tongue he circles it under the head. Sam gasps the first time and
humps at his face for the next few so Dean speeds up until his brother is
whining and thrusting at him.
"I wanna spank your ass too, Dean." Sam pants for air through his open mouth
but still keeps on talking. "Would you like that?" Dean makes the most pathetic
noise in answer and the embarrassment sends a sexual thrill down his guts right
into his cock. "You sounded   great   when she hit you, fucking whining and
begging. I came  so  hard listening through the wall." The image of his little
brother jacking off with his ear to the wall is a hot one; Dean keens and Sam
gives a few ruts before crying out as his cock starts to jump and shoot. Dean
gets the first hot blast in his mouth before Sam pulls back and lays the rest
of it up his cheek and chin, gripping his head by a tight fistful of hair.
"  God,  Dean you look so good like that." He wipes the head of his dick over
Dean's now puffy lips and works the last few drops out into his mouth. "Gunna
come on your face all the fucking time."
"  Shit  , Sam, where do you pick this stuff up?" he's trying to sound angry
but he's winded and still licking Sam's insatiable cock.
"I'm online." Sam replies easily, laying his dick across Dean's cheek and
rubbing it against him with rolling hips while his controlling hand, still
wrapped in Dean's hair, keeps Dean's head still. "Want to see if you can make
me come again?" his brother asks, stroking his half hard dick until, god help
Dean, it starts to fatten up.
They have little problem getting another load out of Sam and this one gets
striped up the other side of Dean's face. Afterwards he takes his second shower
of the day with his brother, who washes him gently in the steaming spray of
water.
 
===============================================================================
 
If Dean could tell his past self that he'd be waiting to pick up his brother
from school with a butt plug in his ass, he'd probably smack himself in the
face. Yet here he is and he cannot for the life of him stop shifting against
the damn thing. A few days ago when he started putting things larger than a
finger back there for the first time it didn't feel  this  good. Clearly
something that gets better with practice so he bought some plugs to get himself
ready for Sam's cock; the thought and the toy have made his hard on throb
swollen and demanding in his pants, and when he glances down his jeans are just
starting to soak through over his leaking dick.
While Dean is contemplating the different ways they could have sex in the car
Sam stalks out of the school building, his bright eyes narrowed at the Impala
and Dean already knows his brother did not appreciate the note he snuck in his
lunch. His erection jumps excitedly at the thought of Sam worked up and
incensed about Dean's surprise.
"Happy birthday!" Dean exclaims through a grin when Sam bends to fold himself
into the passenger's seat and throw an icy look his way the second he sits
down.
"I just went through most of my classes with a huge, annoying hard on thanks to
you."
"I'm sure everyone was impressed." Dean retorts, holding his knowing smile
because it's going to annoy his brother. "What makes you think this birthday
surprise is sexual? I didn't say anything of the sort." Sam stares at Dean's
pants and the obvious state of his cock, glancing up to glare at him a second
later.
"Well, let's see, besides that monster you've been sporting since this
morning  you said you had a special surprise for me and I was going to need to
sleep for a week so... I kinda figured I was getting laid." Dean's grin falters
when Sam reaches for his leg and grabs it tightly. "You better get this car
somewhere no one can hear you screaming my name."
"  Fuck  . Yes,  sir  ." Sam's eyes blow open wide and stare at Dean as he
charges the Impala towards the nearest rural road, thrilling in following Sam's
directions without hesitation.
"Keep calling me that." He orders Dean, who didn't think before he said it but
loves the idea immediately. His hips shift against the toy in his ass forcing a
small noise up out of his throat; of course Sam doesnt miss it. "What's going
on, Dean? So horny you can't sit still?" Dean nods as he skids through the turn
onto an unpopulated stretch of country road and pulls the car behind a tall
clump of bushes.
"Clothes off." Sam instructs the second Dean cuts the engine and he struggles
to obey quickly, his cock thumping back to his belly when he lifts off the seat
and slides his pants down his thighs. Sam sucks in a breath and grabs right for
Dean's ass before he sits back down on it, swearing loudly when his finger dips
and runs into the toy Dean has wedged in him.
"  That's   your present." Dean can hear how desperate he sounds already but he
doesn't fucking care, Sam's mouth is parted and his eyes are wild as he rubs
the part sticking out of Dean. "I'm ready for you to fuck me, sir."
"  Oooh  ,   yes  , Dean." Sam moans, pushing his finger against the toy and
swiveling it inside Dean, who gasps and watches his cock flex and drip in front
of him. "I'm pulling this out so I can get in there   right now  ." With that
he grips and slowly retracts the plug, making Dean tip his head back and swear.
He used plently of lube so the thickest part pops out of him easily and he
groans, missing the fullness already. "I'm gunna fuck you so deep." Sam growls,
yanking his own pants down his slim legs. "Get on my lap."
Dean hurries to kick his pants off and comply, throwing a leg over Sam then
tucking his knees beside his brother's hips. Sam takes Dean's hip in his left
hand and sneaks his right underneath to slide his finger around Dean's slick
hole. He gasps but Sam soon replaces his hand with his nudging cock and rubs
the head against Dean.
"You like that toy up your ass?" It's obvious he did but Sam never tires of
making him blush and admit to things no one else knows about him. It's become
alarmingly cathartic and the more Dean gets the more he needs.
"  Yes  , can you get in me already?" Sam holds his dick poised to enter but
still doesn't and Dean whines in frustration.
"You weren't sure a few days ago and now you want my dick real bad. Beg a
little and I'll let you sit on it." Son of a bitch his brother is way too young
to be this kinky but Dean can't cater to his own pride in this obediant
position; he leans into Sam and pleads.
"Please, sir,   please  fuck me, I'm all wet for you and I wanna be sore when
you're done."
"  Fuck  , De." With that Sam pushes Dean down by the hip, bringing his other
hand up to rest on the opposite side. He feels the firm pressure of Sam's dick
and tries to relax for him, grunting in surprise and pleasure as he slicks past
his muscles to get inside. "Soooo   warm  , Dean.   Ooooh  ,   god  ." Sam
slides up into him halfway, pausing to let them both adjust, which Dean has no
time for.
"Don't stop, Sammy,   please   can I have the rest?" Dean doesn't even wait for
an answer he just sinks on Sam's cock, pulling groans from both of them as Dean
settles into his lap with a gasp. "You feel   huge  ." He's not comfortable
with this much inside him yet but he doesn't care about the stretch when Sam
moans loudly and tosses his head, because Dean will never forget the sight.
"  Don't move  ." Sam's grip on his sides is merciless and his mouth hangs open
as he pants, unruly strands of hair sweat-sticking to his forehead. "It's too
good." Dean wants this to last so he fights the near overwhemling instinct to
grind on Sam's dick, which is burning and throbbing deep in his ass; he had no
idea how powerfully intimate it would feel.
"Are you gunna come already?" he breathlessly teases, knowing if he makes Sam
feel challenged he'll be rougher. "  Please  , sir, I want to move so bad."
Dean squeezes around Sam and he growls, bumping his hips up into Dean, who is
already fully seated on his cock and when it shoves deeper in he nearly shouts.
"  God  , so   much  ."
"You couldn't   wait   to sit on all of it though, huh?" Sam drawls, somehow
remaining cocky while balls deep in his brother for the first time; he never
ceases to amaze Dean, who nods and murmurs into Sam's neck in shy answer while
he shifts his ass back and forth on his dick. "Can't help grinding on it
either, I   knew   you'd love a cock in you." Sam guides Dean up nearly halfway
and then back down again a few times, groaning brokenly each time they push
together. His prodding soon fades away from offensive and heats into a thumping
pleasure that is working gasps and moans up out of Dean directly into Sam's ear
as he pulls him up and down. Dean brings his head back from Sam's shoulder to
mash their lips together while Sam directs his body and the car starts to rock
on her suspension with their increasing motions; the small squeaks are one of
Dean's favorite sounds in the world.
"Holy   shit  ." Dean spits out some minutes later when Sam changes his angle
searchingly, tilting his hips so he nudges Dean in a spot he didn't know
existed.   Prostate  , his general knowledge of anatomy comes up with a few
seconds later while he clings to Sam and makes the most embarrassing noises
because he's never felt anything like   this  . "Siiiiir,   fuck  ,   yes  .”
"  Yeah  , there it is.” Sam huffs out, keeping Dean from speeding up with firm
hands on his hips. “Have you hit this spot before, Dean?”
“No, sir.” Sam holds his angle and fucks into Dean steadily until he’s letting
out little sobs with each thrust and he feels like he might come from rubbing
his cock on Sam's stomach; he hasn't even touched himself yet. "Fuck." Sam
groans and kisses Dean brutally hard, rocking his dick into him until they both
moan in tandem.
“Feels so good, Dean, and it’s makin' you all drippy.” Dean has always leaked
more than the average guy but when he looks down he sees he’s made a sticky
mess of his cock, balls and Sam’s abs, a drool of it hangs from his bobbing
hard on. “You wanna come, don't you?”
“God yes, please Sammy.”
“I can feel how close you are but I wanna keep fucking your virgin ass, best
present you ever got me.” Sam lands a sharp smack on Dean’s butt and he jumps
in surprise, squeezing vicelike around Sam, who cries out when he thrusts up
hard. “Oh my godyou just got so tight." He spanks Dean again even harder and
hauls him down into his lap, grinding his cock deep into his brother.
“Fuck, Sam, you’re so far in.”
“That’s where I’m gunna shoot it, so you can keep it up there." Dean can't even
find words to reply to that and so simply whines in his ear as he continues.
"You wanna ride me like a girl? Make me come real hard in you?" Another loud
smack on his ass and Dean whimpers, his tense body making Sam moan again.
"Fuck   yes  , sir, can I?" Sam grunts and nods rapidly, releasing Dean's hips
at last as he winds his arms around Sam's neck to get purchase; now he can
alternate bouncing or grinding while keeping Sam's cock almost fully in him. It
keeps tapping that sensitive spot and either Dean is coming or dying - he can't
decide. A minute later Sam suddenly takes control back, gripping Dean's hips
and speeding him up.
"You're so fuckinghotinside, Dean, I'm gunna come in you." Sam's hips bounce
counter to Dean's for a few coordinated seconds and that's all it takes for him
to snap up and squeeze Dean's sides painfully as he opens his mouth and
bellows, squirting warm and deep inside him as his cock pumps and twitches.
"Oooooh, fuck yeah." he moans breathlessly as Dean tries to keep riding him;
when he lifts up Sam stops him firmly. "Don't move, I'm still coming." Sam
starts jerking Dean's weeping hard on quickly, and when he feels his brother's
come leaking out of him and his pulse through his cock inside him his own load
pushes up, out and onto Sam's shirt and hand while he howls in his ear.
"  Fuck  ." Dean sighs out, still impaled on Sam's cock and leaning most of his
weight onto him.
"That was   amazing  ... keep my come inside." Sam instructs, lifting Dean
slowly off of his lap; when his dick drops free a few drips follow but Dean
clenches up on the rest. "Good boy." Sam praises, Dean collaspses to lay on his
back across the seat beside him and glows in the approval. Sam could   never
call him that in the heat of a hunt or combat but here the endearment makes
Dean's chest feel full and his body sated.
Sam's legs are spread and his half hard cock lays moist over his thigh; he's
grinning down at Dean with sated hazel eyes that look him over like a meal.
"What?" Dean asks softly, his brain struggling with post fucking haziness and
the empty, tender feeling inside himself. Sam takes either one of Dean's legs,
which were bent against him as Dean sprawled across into the driver's seat, and
lifts them up and out, opening Dean up and putting him into a missionary
position on his back.
"I wanna see." Sam explains simply, taking one hand off Dean's ankle to slide
back to his sore hole. Dean grumbles a little and shys away from Sam's face
when he dips it down and close to Dean's ass. "I'm gunna lick you everywhere."
Sam swipes his tongue across the inside of his ass cheek and Dean jumps but his
cock twitches with intrest. "Maybe try to suck your big dick, would you like
that?"
"Hell   yes  , sir." His little brother's eyes narrow with purpose and he lays
one of his hands across Dean's stomach possesively. Dean hasn't felt more owned
in his life, it's surprisingly pleasant.
"  Good   boy."
