Summary
     Sam's in heat and Dean is there to make it all better
Notes
     Written for Cindy because yes.
It's hot. Almost unbearably so inside the motel room which doesn't help the
fact Sam's gone into heat. Windows are open, curtain fluttering in the humid
air, and no fucks were given to anybody whom decided to pass by their room
because there was no way in hell Dean was stopping. He's got his baby brother
under him, face pressed into the mattress beneath them as his fists grip the
blankets tightly. Sam's begging Dean, begging him so needily to stuff him
already and Dean's half tempted to skip the foreplay and do it already.
But he doesn't. He's got his right hand pressed firmly against the middle of
Sam's back to keep him from squirming so much as he licks up the back of his
Omega's left thigh. Dean licks up the trail of slick threatening to drip onto
the bed, growls at the offending mess as his other hand busies itself with
rubbing a thumb over Sam's puffy red hole. The Omega keens loudly, voice high
and rough with use as he tries arching his back more at the first touch of
Dean's tongue against his hole after licking up slick. Dean growls again, a
deep note inside his chest that sends a visible shiver down Sam's spine as his
asshole winks at Dean nicely.
“Needy little bitch Sammy.” Dean purrs seductively as he dives in and licks
around Sam's leaking little pucker, making the Omega spurt a fresh dollop of
slick right against his Alpha's tongue. “Yes, yes yes-,” Sam moans, voice
chanting just one word as he licks his lips, tongue catching on the sheets
under him. “/My/ needy little bitch.” Dean says against Sam's ass, sucking at
his tail bone as he listens to his brother. “Yours, all yours Dea.” the Omega
squirms against Dean's hold, trying to get that mouth to go back down; which
seems to work because Dean moves his head back down to press his tongue swiftly
into his hole, muscles clenching tightly around the much needed intruder.
“Dea, fuck...yes! More.” Sam blurts out as his fists grip harder at the sheets,
tugging them closer to his body as he feels his brother's face still pressed
firmly to his ass. The Alpha grants Sam more with a wiggle of his tongue and
works in a finger alongside his tongue into Sam's hot, tight heat. Dean groans
against Sam's ass and pulls his face away, but keeps his finger inside. He
quickly adds two more fingers when he's sitting back on his haunches, watching
Sam panting heavily, knows his Omega's so close to release and moans softly.
“Gonna fuck you with my dick soon Sammy. Stuff you like some Thanksgiving
turkey.” he grunts out at the repeated clenching of Sam's ass, feels the slick
pushing out despite the fingers doing their best to plug him up.
“Come, come on. Can't wait. Don' wanna.” Sam mumbles into the sheets as he
tilts his head a bit more to glance back at his brother, pupils blown wide with
lust. There's a wet spot on the blankets that tells Dean his Omega was drooling
and that plus the sight makes his dick twitch hard. “Fuck, yeah...yeah Sammy.
Shit,” Dean groans out as he pulls his fingers free from Sam's ass and quickly
shuffles in close to let his dick take their place. He's lining himself up, wet
hand slicking up his length quickly with Sam's own natural lube as his head
bumps against Sam's waiting hole. It makes them both groan with anticipation as
he presses inside with as much care as he can despite his dick demanding him to
just slam in already.
The Omega's groan shifts into a long needy moan as he feels his Alpha's dick
finally pushing home. “Jesus shit, you're so fucking slick!” Dean moans out as
his cock slips nice and deep, hips pressing firmly against Sam's ass. “I's all
for you. For Alpha.” Sam moans breathily as he feels Dean's fingers curling
around his hip bones and pulling him back, feeling Dean trying to push in
deeper if possible. “Your first heat wasn't even this wet!” Dean blurts out as
he looks down at where they're connected and whines. “I's cause Omega's don't
leak...nnugh fuck-, we don' produce...our full amount.” Sam stutters and moans
again when Dean decided to pull out of his ass and slam back in quickly.
“Tha's not what I meant. Was sayin' you're...” Dean breaks off into a sudden
moan when Sam decides to do the same thing back to him. He pulls forward only
to slam his hips back against his brother suddenly, knocking the Alpha onto his
ass on the bed. It takes Dean a moment to realize what happened, but it's just
a wee bit slow when he's suddenly got a lap full of demanding Omega. He manages
to get his hands back on Sam's hips when he feels little fingers wrap around
his cock only to push him quickly back into that oh so sweet heat once more.
“Through with talkin'. Jus' fuck me already.” it's Sam's turn to growl roughly,
hands slapping against Dean's chest to hold Dean down on the bed as he gives
his hips a practice roll.
Both give twin moans of pleasure as Dean's legs curl up, knees bent and heals
pressed into the bed to give himself better grip. Sam gives another curious
thrust as his eye lids drop shut at the feeling, jaws seeming to stay parted as
Dean gathers himself. He gives Sam a few more moments to play before he clamps
his hands down hard on Sam's hips and starts thrusting up into the Omega
quickly. It's a fast pace that leaves Sam bouncing on top of Dean, trying his
best not to topple off as his dick slaps against Dean's belly, skin smacking
against skin nicely. “Mm, nngh, yes yes Dea, fuck!” Sam moans out as Dean
continues to fuck up into his brother, sweat sliding down his forehead and into
his hair.
It doesn't take much for Dean's knot to start swelling, catching every few
thrusts on Sam's asshole and causing the Omega's breath to hitch at the sudden
tug. Not much longer before it's harder to continue the pounding and he slows
down once his knot pops back inside Sam, letting his hips to press back down
onto the bed. They're both panting heavily, Dean more so as the Omega grinds
his ass down on Dean's dick, moaning sweetly. “Fuck yourself on my dick baby.
So close to knotting you already.” Dean groans softly as he feels Sam shifting,
hands getting a better place as he pulls himself up and gently off Dean's knot
before dropping himself back down suddenly, filling himself back up. He does
this a few more times before he's suddenly tensing up and coming hard, come
splattering across Dean's stomach as he continues to keep himself from dropping
down on Dean's knot.
“Holy...fuck, shit baby!” Dean watches his brother come undone, cock twitching
with each pulse, asshole clenching around his shaft till he's empty. Dean let's
his hands drift up Sam's sides, but he doesn't get too far when the Omega
suddenly drops himself down on his knot, feels only the slightest pressure
before he's being enveloped in that delicious heat and moans rather loudly when
his orgasm gets ripped out of him. It's too soon, his knot wasn't even fully
swollen, or it was and he just wasn't aware of it. His head is pressed back
into the bed as he feels his dick squirting come deep inside his Omega's ass,
feels Sam still shivering and twitching with the end of his orgasm. Dean's mind
is blank for what feels like the rest of the night as he comes around from his
orgasm to see Sam looking down at him with the biggest shit eating grin on his
face.
“What's got you smilin' like that?” Dean asks with a smile as he pulls his
hands away from Sam to arch his back in a sudden content stretch that makes his
toes curl. “You looking so hot when you came.” Sam admits with a shrug of his
shoulders and Dean actually blushes a bit. “Shut up bitch.” he mumbles out, but
there's no heat in his words as he can't hold back the smile that forms on his
lips. “Make me.” Sam teases softly as he leans forward and smiles when Dean
just grunts before pulling him in for a deep content kiss. They're still tied
together and will be for a good hour or so, but that's quite alright when you
got an in heat Omega squirming in your lap and knows that by the end of said
heat there's no way Sam's /not/ going to be pregnant.
