Summary
     Jeans still around his ankles, sitting on the motel bed not even five
     minutes after he’d come in the door and told Sam that Dad wasn’t with
     him, stopped to see a friend on the way back, and there are still
     school books scattered open on the table. But Sam’s throat is open,
     too, right here, just for Dean right now. Not always just for Dean.
“Jesus Christ Sammy, you’re such a fucking slut.”
Spit trickling down his chin, eyes dilated wide and shaggy brown hair all
mussed up, with a wet pull Sam popped off his cock and smirked, “Yep.”
He made sure to pop that ‘P’, smacking his lips together before swirling his
tongue messy around the head of Dean’s cock.
“Fuck, and you just… gave him a blow job to get a ride home cause it was
rainin’?”
Sam’s bony narrow shoulders shake with a laugh, “No, Dean,” licking all over
his dick drooling like a dog, Sam nuzzles between his legs, “I sucked his dick
cause I wanted to, he gave me a ride home cause he thought I needed it.”
“Fuck…”
“That’s not even the best part,” rubbing his smooth cheek against Dean’s cock,
nimble little hands rolling his balls gently, Sam looked so good down there,
“he wasn’t that thick, not like you, but he was long and he pushed right up
against my gag reflex, I choked on it and started crying, an’ I think it made
him excited…”
Grabbing into Sam’s long hair, Dean shoved his cock past those bit swollen lips
and into the silken heat of Sam’s mouth, shoving back far enough to hit his
throat, feel that body jerk reaction as Sam’s hands went to his thighs and
squeezed. Yeah, he always cried a little when you hit him there just right,
eyes shiny wet and begging, Dean just never knows for what but he knows Sam’ll
curse him out if he pulls back or goes easy.
Jeans still around his ankles, sitting on the motel bed not even five minutes
after he’d come in the door and told Sam that Dad wasn’t with him, stopped to
see a friend on the way back, and there are still school books scattered open
on the table. But Sam’s throat is open, too, right here, just for Dean right
now. Not always just for Dean.
Pulling Sam off when his body starts shaking too bad, hoarse coughing and his
spit’s thick as it trails down his chin, Dean flings him on the bed.
“So that was just the first night huh?”
“Yeah.”
Tearing Sam’s clothes off roughly as Sam tries to shimmy out of them even
faster, flipping onto his belly and pushing up on his hands and knees, Dean
kicks off his jeans and rips his shirt over his head.
“Who else?”
“You remember that pretty waitress, Minnie, from the Starlight Diner few
streets over?”
Dean pauses, oh he remembers Minnie, but really? Sam? Sure he looks older than
sixteen for as tall as he’s shot up but he’s a scrawny twig. He has got the
floppy hair and puppy dog eyes that girls love though. But Minnie, she’s a
woman.
“Minnie? Really?”
Sam’s smirking over his shoulder as he pushes his ass back and Dean palms the
firm little cheeks of his ass to squeeze and pull them aside, diving down. Sam
gasps but he keeps on talking, “I went to the diner and pulled some crumpled
ones out of my pocket, asked what I could get for it and looked at her just
right and Minnie asked me where my parents were…”
Pulling back, and Dean really doesn’t want to, “Jesus, Sam you gotta be careful
what you tell people –“
“- I am. You should of heard her Dean, she took me back to her place, I got her
nice and wet on my tongue first before fucking her into the mattress, god she
was so wet.”
Dean loves listening to his brother’s filthy mouth, hearing talk about this
dirty shit while he’s got his tongue on Sam’s ass, spit shiny and so easy to
take him in. Fingers rubbing that sweet soft crease between Sam’s legs as he
gets his tongue worked inside, just a little downy hair Dean barely notices.
“… you would have loved eating her out Dean, her pussy had that perfect tang to
it, just dripping, I came on her tits and licked it off -“
Groaning, Dean made room for his spit wet fingers inside of Sam, pushing past
the tight muscle and twisting down, making Sam scream for it. One broad hand on
his bony hip, Dean pulled Sam back and bit at the clenching muscle of his hole,
at the inside of his ass cheeks leaving teeth prints dented there as he spit
loudly and squirmed another finger inside.
“Hitch hiking the first day, Minnie the next, you find someone every night Sam?
Didn’t you want to stay behind cause you’re busy at school?”
Sam pushes up on his hands and glares over his shoulder at Dean, “I’ve been
doing fine at school. You want to hear about the guys I sucked off for money at
the pool hall?”
“Shit. You. How many?”
“I don’t even know, I think it was like, seven of them? A few of them fucked me
too.”
Six days, Sam hadn’t even been left alone a full week. At least the job was
easy enough that Dean and Dad could cover and he’d convinced Dad to leave Sam
on his own, always such a fucking stubborn kid and so angry it takes twice as
long to do anything with Dad and Sam in the same room. Well Sam was sure living
it up. Dean wasn’t mad at him, not really. Wasn’t even jealous, maybe a little.
Mostly, he was kind of proud.
Pulling Sam back and standing on shaky legs to take the few steps to his duffle
in the corner, digging out a tacky bottle of lube, Dean sprawled on the bed on
his back and patted his lap. Sam, cock bobbing in front of him and belly shiny
with pre come and sweat, ridges of muscle starting to show on his lanky frame,
hip bones pushing out all knobby knees and elbows - Sam’s a mix of awkward and
young, too experienced and eager.
Dean slicks his cock up and he’s still got a hand on it when Sam’s sitting down
on him, one wide palm splayed on Dean’s chest as he hunches forward and takes
it all with a stuttering groan.
“Yeah, come on Sammy, tell me about it.”
There’s a couple fighting in the motel several doors down shouting to raise the
dead, traffic passing loud on the freeway in front of the cracked asphalt, a
dumpster being slammed somewhere, all Dean can hear is the way Sam breathes
roughly, how he exhales with a little whine when he sinks down, how he groans
when he pulls up and Dean chases him with a snap of his hips, the bed creaking
under them.
“I uh – I wanted to play some pool, see if I could shark as…. As good as you
but uh, I – shit Dean – “
Fingers digging into his hips Dean pushes his feet flat against the bed and
bends his knees to fuck up into Sam’s tight little body, his cock slapping up
against his belly and his balls draw up so tight Dean can watch himself sink up
into that smooth hole, not even sure where it all goes.
“- I did, pretty good – at the pool – but I lost, they told me if I uh, if I
wanted to make it back I could, so, ssoohhhhh…”
Curling one hand around Sam’s cock and balls, squashing them up against his
belly and dipping the fingers of his other hand between Sam’s legs, Dean loves
to feel the stretched hot muscle dragging over his cock, feel it with the pads
of his fingers pushing, always pushing for more.
“They took me to a back room and they didn’t – ungh, didn’t even have to tell
me, I just, just sank to my knees, it was so fucking dirty back there Dean,
someone dropped a twenty in my lap and I just opened my mouth –“
Crying out, Sam arches his back and leans backward, reaching behind him, and
Dean pushes his knees up high enough Sam can brace himself on them and ride
Dean with a deep roll of his hips. And he’s still so fucking skinny Dean can
see his cock pushing against Sam’s belly just under the navel, pushed so deep
inside, smooth flat belly tight between bony hips.
“ – the first one took the longest, he came on my face, laughed and smeared it
around with his cock until someone pushed him aside, dropped another twenty on
my lap, shoved in, they took turns back and forth, some held my head from
behind, shoved their fingers in my mouth to pull my lips open wider, I don’t
remember how many there were, they just – just kept, kept on coming –“
Sam’s whole body snaps taut and quivers when Dean gets a finger in past his
rim, sliding up into crushing heat alongside his dick tugging at the rim
pulling Sam even wider, wider. Slapping the vivid purple bruises marring the
inside of Sam’s thighs – that Dean definitely did not leave there – Dean tugs
on his hole.
“Yeah, Sammy, they the ones that left you these?”
“N-n-nooo, De, no. Someone, ungh, pulled my jeans down and I made sure they
wearing a condom and I spread my legs for it, god, it was so good, it hurt, but
they didn’t, didn’t leave hickeys –“
Humming, Dean stroked Sam’s cock in loose, slow pulls as he fucked his little
brother on his cock and his fingers – two now. “So who left these?”
“That wasss, ungh, was, this girl from school, I went over to do homework,
after school.”
Sam takes a deep shuddering breath and Dean can see his whole body start to
shake when he lifts up on his knees and starts fucking down onto Dean’s cock
and fingers now, determined, thigh muscles flexing and he’s got such nice
slender legs still so downy soft, mottled with purple bruises up towards the
crease of his hips.
“This girl, A-amanda, we study together, her father wasn’t home and we, she let
me eat her out, fuck her on my fingers, and after she went down on me, liked –
uh – to, liked biting, I didn’t realize she was marking me –“
“She taste as good as Minnie?”
“N-n-no, wasn’t too good giving head, too much teeth, but uh – her dad offered
to give me a ride home, after dinner –“
“Really? Her dad too?”
“He wanted to suck me off, parked in an empty lot, he was better than his
daughter, I told him he could - he could, fuck me in the back seat, folded me
up like a pretzel … didn’t even ask about the bruises on my thighs – “
“Christ –“
“He was balding, had a beer gut, but his cock was so thick, and he was mean,
liked to – to pinch my nipples –“
“Sammy – “
Bouncing on the bed, jostling Sam up one hand holding steady on his hip while
Dean fucked him three fingers and a cock deep, didn’t even take a flick to his
dick and he was shooting off, sticky wet all up Dean’s chest even hit him on
the cheek. Body clenching vice tight around Dean, he let Sam coax it out of
him, greedy little whimpers and needy shoves of his hips, fingers still
clutched to Dean’s knees, body bowed back and cock pushing out underneath his
stomach.
Pulling his fingers out first, wet messy squelch of Sam’s loose hole dribbling
down on him, Dean heaved Sam up and over onto his back. Sweaty and flushed
blotchy pink, Sam was boneless and giggling when Dean shoved between his legs.
Hole gaping with a pink flutter Dean could see the red red inside of Sam’s body
where who knows how many fucking people got into him this week, dripping white
now, thighs spread wide.
Dean bit over every purple hickey on Sam’s thighs and made them darker, made
him squirm and whimper before licking up in between Sam’s legs, tongue sliding
easy into his fucked out body. Lapping at his fever hot skin, Dean hadn’t been
with anyone else but his brother for months now. Hands stroking Sam’s quivering
belly, kissing and rubbing every dirty not so secret part of his body, Dean
languished in the warm after glow.
“Such a fucking slut Sammy, none of them ever enough, not what you want, huh?”
Sam smiled loopy at him, reaching down to scratch through his hair. “No.
Because they’re not you.”
