Summary
     Weecest porn written because Isa and John's steamy cosplays are too
     good to pass up, and Frances inspired me with sweaty sex. It's
     summertime and Sam is sweating through his shirt and Dean knows it
     isn't right to want to bite his neck and run fingers over that sweat-
     slick skin but... well, it fucking happens. Enjoy the porn.
Notes
See the end of the work for notes
Dangerous things were an area of expertise for Dean. He knew it was dangerous
to be out on a full moon, knew it was dangerous to walk alone at night, knew it
was dangerous to hang around certain forests at certain times of the year, and
he especially knew it was dangerous to be anywhere near his little brother when
the weather was warm.
Sam turned into Dean’s personal tormentor, like a mirage that was constantly
out of reach.
Because Dean knew his feelings towards his brother were a little bit more than
fucked up. Knew it from the way he had the immediate urge to bite every time he
saw Sam’s exposed neck, knew it from the dreams that left him rutting against
the bed sheets with his little brother’s name spilling out of his mouth, knew
it from the time Sam had left the toilet door open whilst masturbating and
Dean’s first instinct was to stop breathing and treasure this moment.
And in summertime Dean didn’t just know these things, he lived them. It was
damn hard already, with Sam being all growing-up and developing-muscle and
stretching like a cat on the couch with the muscles of his back bunching and
then releasing, his plush ass pushing backwards, his shoulders rolling and his
neck stretching andJesusDean was hard.
But put that wet dream into cut off shorts and you had yourself a real life
pornography star, right there in the living room. Or worse, keep that wet dream
in his jeans and long sleeves and watch as the sweat beaded on his neck, and
Dean didn’t even have a namefor what kind of sexually explicit that was.
But Dean was a big brother, and there were certain duties associated with that
title that didn’t involve penises or asses (no matter how plush and delicious-
looking), so Dean didn’t stamp over there and pin Sam to the couch and thrust
his hard cock against his brother’s cheeks and bite into his neck and pull his
shirt up slowly.
Dean just walked over and sat down on him.
“Dean!” Sam squealed happily, kicking his legs and letting Dean fall onto him,
engaging in the wrestling that was second nature to them.
It was only a moment before Dean’s life went straight back to sucking again,
namely in the curve of Sam’s body against his, the gentle puff of air that was
suddenly close to his face, and Dean was breathing and his eyes were darting
from Sam’s dilated pupils back down to Sam’s parted lips and shit he just
wanted one taste.
He and Sam scrambled away from each other simultaneously, limbs flailing, arms
shoving until they were at opposite ends of the couch, awkwardly looking
anywhere but each other.
Sam looked… really fucking sad.
“M’sorry Sammy,” Dean said, because it was his job to make sure Sammy was okay.
“I don’t want you to be.” Sam replied, and it was so soft and so ambiguous that
it took Dean a moment to understand what he had said.
“Sam?”
“Shut up,” Sam said sadly, and he looked away and his face was blotchy and it
looked like he might cry, so Dean sat up, scooched towards him and tilted his
face.
Sam looked at his big brother through wet eyes, and Dean offered a second’s
reluctance before leaning in and pressing his mouth against Sam’s.
Sam gasped against his lips, mouth soft and pliant until he was kissing back
hungrily, tongue darting past his lips and claiming Dean like he wouldn’t get a
second chance, like maybe they didn’t have a second chance to do this, and the
very thought that this might be the only time made Dean crumple backwards
against the couch, dragging Sam with him, pulling that body against his and
thinkingmy little brother is on top of me and we are kissing on a couch and
life could not be more fucking perfect.
God, he tasted incredible as well, salty bitterness of tears and the sweetness
of his tongue and the plush lips that combined to make Sam some kind of living-
and-breathing Tequila Shot.
“De-” Sam breathed, pushing his hips downwards so Dean could feel the line of
his cock, snug against the inside of his thigh, their jeans pressing together.
The hair Dean pushed back from his forehead was damp with sweat, and Dean
trailed his hand over Sam’s shoulders and down towards his ass, pressing it
closer so their cocks were next to each other, hard flesh next to hard flesh,
and Sam whined at the contact.
With his mouth open, Sam started pressing kisses and licks to Dean’s jaw, new
stubble and forming muscle jumping under his little brother’s tongue, and
Dean’s lips were parting and words were coming out, words that didn’t make
sense until Dean realized it was just a litany of his little brother’s name.
The hand on Sam’s ass was moving to press against his lower back now, feeling
the sweat on his skin in a slick slide that was impossibly erotic, and Dean’s
hips pressed upwards and Sam pushed downwards and they formed an urgent kind of
rhythm, Sam’s open mouth resting on his shoulder as the muscles in the back of
his thighs flexed with each thrust.
“God, Sammy, Sam, fuck,” Dean told him, pleasure almost painful in constricting
denim, wondering if Sam was as close as he was, wondering how long Sam had
wanted this – if Sam wanted this. “Sammy please tell me you want this.” Dean
gasped out, clutching at his little brother’s ass again.
“That’s the stupidest thing you’ve ever said,” Sam informed him before biting
down against his neck, his voice high pitched and too-fast. “Wanted you
forever, want you all the fucking time, Dean never want anyone else ever god
Dean, fuck.” Sam spewed out, words a hot breath on Dean’s neck that pushed him
ever so closer to the edge.
“Gonna come, Sammy.” Dean warned.
“Want you to, want to feel it, please Dean.” Sam groaned, body spasming as his
little brother came, and Dean joined him, feeling come hitting the inside of
his briefs and soaking through, cock twitching, eyes open to watch the
expression on Sam’s face as he slowly rode out his orgasm.
Eventually they both crashed against each other, Sam’s sweaty face buried in
Dean’s sweaty neck, both of them puffing and winding arms around each other
even though they were both overheated.
“Love you, Dean.” Sam huffed, and Dean smiled, because keeping Sam happy was
his other area of expertise.
“I know. Love you too, Sammy.” Dean replied, and Sam already knew.
