****** Sweating After P.E. ******
by Exaggerated_Specificity
Summary
     It's early in their sexual relationship. Sam is 15, Dean is 19. Dean
     waits for Sam after P.E. and they fuck between the temp buildings.
     Shameless PWP written for SaltandByrne based on a prompt by
     xsnappapplex on tumblr.
Sam still had his gym clothes on, sweat clinging to the creases of his thighs
and the small of his back. Dean thrust his jean covered thigh between Sam's
knees and pinned his scrawny arms over his head, Dean's tongue half way down
his throat, in the narrow, shady space between the temp buildings adjacent to
the football field. Dean had been waiting for Sam as he headed back to the
locker room after doing his mile run in P.E. Dean getting Sam's attention with
a whistle and pulling him to their secluded space quickly, before Sam's
classmates could notice.
Sam was already hard as a rock, breath vibrating in his lungs as Dean ravaged
his mouth. Dean's lips and tongue were heavenly, sending jolts of pleasure
straight to that tender place behind his balls. This aspect of their
relationship was still so new, so scaldingly hot. Every nerve in Sam's 15 year
old body was buzzing with the electricity of his brother's touch.
Dean pulled away, momentarily breaking their kiss, whispering with a lust
addled voice, "Fuck, Sammy. You gonna come for me already? I haven't even
touched you yet."
After a subtle smirk, Dean's lips and tongue were back on Sam's neck, lapping
up the droplets of sweat trickling down from his hairline. Dean released Sam's
arms and began palming Sam's ass, spreading him open beneath the thin fabric of
his gym shorts. Sam's breath hitched again. Just thinking about what was next
had Sam's teenage hormones hurtling him toward orgasm. Tilting his hips up,
desperate for more friction, a broken whimper escaped Sam's lips. Dean's lips
were at his ear again, "That's right baby boy, come for me. Give me something
to slick up that tight fucking hole before I make you ride my cock."
Sam groaned with animal intensity at Dean's words, the muscles in his abdomen
flexing, his head tilting back against the metal siding. Dean hooked his thumbs
into the elastic band of Sam's shorts and yanked them down quickly, eager not
to waste what was sure to be Sam's first load of the afternoon. "Yeah Sammy,
come for me."
Dean's deep voice shakes Sam to his core and he lets go, relishing in the
feeling of his balls tightening, muscles pumping his seed up and out, spilling
violently over his bare stomach and the fingers of Dean's right hand which
eagerly awaited his release.
Sam can hear Dean's other hand unzipping his jeans and freeing his sizeable
cock from the confines of his boxers. "Turn around for me baby." Dean groans.
Sam complies quickly, slipping one sneakered foot out of his shorts in the
process. Dean's come filled hand slid up between Sam's cheeks, slicking his ass
crack with his own rapidly cooling seed. Dean's fingers teased Sam's hole,
slipping in and depositing come as they worked their way deeper. Tip of one
finger, then two, back to one, then sliding further in, past the first knuckle,
and the second, joined by the second finger, both sliding in so, so deep and
beginning a smooth thrust, twist, thrust pattern. Dean's calloused knuckle
caught against Sam's prostate, slipping out and teasing his sensitive rim.
Sam knew he was groaning loudly, he couldn't help it. "Shhh baby brother, you
don't wanna get caught do ya?" Dean crooned into his ear, "Gotta let me fuck
that pretty hole first Sammy, gotta let me mess up that tight little asshole so
I can lick it clean..."
Dean's dirty mouth was having the opposite effect on Sam's volume and Sam had
to bite his lip, drawing a little blood, to keep from keening even more loudly.
Dean had three fingers inside him now, twisting and stretching him to
readiness. "I'm gonna fuck you now Sammy, you ready?"
"Fuck yes Dean please!" Sam groaned, again more loudly than appropriate given
their compromising and semi-public location. Dean slid his left hand up through
the thickened semen still clinging to Sam's stomach and used it to wet his
thick cock, sliding it over his head and shaft, mixing it with his own pre-
come.
Dean pulled his fingers out of Sam and lined up the hot purple head of his
prick with Sam's prepped channel. Applying slow, even pressure Dean pushed in,
breaching his brother's tight heat. "Oh fuck Sammy, you take it so good for me.
Look at you taking my big cock. Christ."
Sam had taken Dean before but despite his thorough prepping, the burn had Sam
grasping the siding in front of him and gasping for air. Dean's hands soothed
up and down Sam's sides, sliding delicately over the smooth skin of Sam's bare
ass. "Shhh Sammy, it's alright, I'm goin' slow, gonna make it so good for you.
Take it like a good boy for me baby and I'll kiss it and make it all better."
After the soft words and slow progression, Dean had entered Sam to the hilt.
Sam could feel Dean's balls press against his own as his thumb traced over the
stretched rim of Sam's asshole. Sam breathed deeply and felt the blood begin
rushing back into his cock, the feeling of extreme fullness and pulsing heat of
Dean inside him was too much. As if Dean could read Sam's mind, he began a slow
exit, only pulling out a few inches before slowly sinking in to the hilt again.
Sam's arousal had him quickly loosening around Dean's shallow thrusts, he began
pushing backwards into Dean's thrusts, signaling his brother he was ready for
more. Dean's pace accelerated, aided by Sam's eager thrusts back. "Fuck, I'm
not gonna last," Dean gasped breathlessly.
Sam was riding back on Dean in earnest now, determined to come again before
Dean was done. But Dean's hips began to stutter in their rhythm and he gripped
Sam's hips roughly, pounding harder into him. "Shit, Sam - I'm!! Unnngh!" and
with that Dean was unleashing hot and deep within Sam's body. Dean's thrusts
slowed and stopped and he held still, buried deep inside Sam. Dean feeling the
gentle pulse of Sam's still eager hole trembling around his softening cock.
Dean leaned down over Sam's back and kissed the droplets of sweat on his spine.
"Now I'm gonna clean you up like I promised baby boy," Dean whispered. Sam
shuddered with arousal as Dean slowly pulled out, his cock slipping free, still
heavy with the remains of arousal.
Dean knelt in the dirt, spreading Sam's cheeks open. Flattening his tongue,
Dean took one long lick up Sam's crack from his taint to his tailbone, scooping
up as much of their mixed seed as possible. Drinking it down with a guttural
groan, Dean sealed his lips around Sam's swollen hole, gently kissing and
suckling, drawing out more of his come. Dean keeps licking and sucking -
gently, reverently. Sam's breathing is again hitching in his chest as he savors
every swipe and suck. Dean pulls back, "Turn around Sammy, I want you to come
for me again."
Sam turned slowly, his limbs leaden with lust. He looked down at Dean and was
almost overcome by the sight of Dean's blown pupils and swollen, red lips.
Before Sam can even utter a moan, Dean's wet mouth is sliding over Sam's head
and down his shaft with a low groan. Sam gasped and threw his head back once
again, his fingers sliding up the back of Dean's neck, into his short, sandy
hair. Dean deepthroats Sam until his eyes water and then pulls back with
strong, even suction.
It's more than Sam can take. With a moan Sam is spilling over Dean's tongue,
Dean pulled back letting some of Sam's seed spill out onto his lips. He licks
them clean only after Sam looked down at him again a few moments later. Sam
sucked in a breath, shut his eyes and cursed under his breath. He's pretty sure
he's never seen anything hotter and feels his cock twitch again. Dean stood up,
putting his cock away and righting his clothes as he kissed Sam deeply. Sam
groaned happily at the musky, bitter taste of their shared loads on his
brother's tongue. Once Dean finally pulled away, Sam bent down and stepped back
into his shorts, pulling them up. "See you at home kiddo." Dean said softly,
planting one last moist kiss on Sam's lips.
Sam stayed in the shade as Dean crossed the field, toward the parking lot where
he left the impala. Sam swallowed hard and really hoped dad would still be gone
when he made it back to their rental home.
