Summary
     Dean thought that maybe under the coy little smile of the local high
     school's swimming captain he'd find a stammering virgin. If only.
     [Cas is 17, Dean's in his early 20's]
Notes
     Found this_prompt in the kink meme and decided to take a shot at it:
     I would really like to read about Dean as a lifeguard and Cas as a
     boy on the schools dive team. Dean (early 20s) can't stop watching
     Cas (mid to late teens) in his little speed-os and starts "pulling
     pigtails." Calling Cas 'pretty boy', pushing him in the pool,
     slapping his cute little ass with a towel, and trying to make Cas
     blush. All of this leading to really aggressive locker room sex with
     Cas egging Dean on and teasing that Dean isn't fucking him hard
     enough. Cas topping from the bottom, dirty talk, slight humiliation,
     any other kinks except scat are welcomed and encouraged!
     I hope the OP likes it as well as subbycas over on tumblr, who
     happens to be the reason I found the prompt in the first place.
     Written and edited quickly because I was really excited to see the
     prompt. Hope you enjoy it.
It all started with the speed-o, really. Well, maybe it actually started with
Cas' laugh and the sly little smile he sent Dean's way. In the end it didn't
matter, Dean still found himself watching the little piece of jail bait swim
team captain more than the actual pool the team was practicing in. That was
just downright dangerous. So Dean was doing everyone a favor, honestly,
relieving them both of the tension. He'd told Cas to meet him in the lockers
after the pool closed. He was right there and right on time, in nothing but a
loose-fitting pair of swim trunks and a threadbare t-shirt. That much Dean had
counted on. What he hadn't counted on was the way Cas' eyes turned downright
predatory, throwing him onto the floor and mounting him. The ass he'd admired
for weeks ran over the length of his cock as it filled, fabric dragging against
the shaft and head roughly.
Dean smirked and pushed up into it. “What you lookin' for, pretty boy?”
Cas growled yanked Dean's t-shirt off. Literal yanking that had Dean flailing
around for a moment under the force. It was almost cute, all that enthusiasm.
Dean shot up and pulled Cas' shirt up by the bottom hem, dragging it over his
head and down his back, trapping his arms in the sleeves. Power flowed over to
his side, Cas' eyes wide as Dean leaned in for a kiss.
That tongue, Jesus Dean needed that tongue other places. Cas flicked it around,
curling it and flattening it out alongside Dean's. Of course it was a show,
just made to rile him up and fuck if it wasn't doing the job. Not like Cas
needed to know that, though. Dean wasn't going to let a seventeen year old get
the better of him. Well, not again.
Kissing slowed them down, the urgency turning to something a little more
manageable. Cas freed his arms and put his hands on Dean's back, feeling the
muscles under the tanned skin before the blunt edges of his nails dug in and
drew welts across Dean's shoulder blades. Dean reeled back from the kiss and
shouted, panting while Cas chuckled.
“What the fuck?” The glint in Cas' eyes was dangerous, challenging him. It
seemed like he knew Dean was always the one in charge, the one leading where
everything went. The edges of his teeth when he smiled told Dean that if he
stayed, Cas was going to turn him inside out and snap him around worse than any
beach towel.
“C'mon, Dean, don't tell me you can't handle me now that I'm here.” Cas cupped
his jaw with one hand, the other drifting down to grip his cock and squeeze.
Dean's eyelids fluttered, the entire front of him nothing but heat where Cas
straddled his thighs. Lips were on the shell of his ear, another chuckle
worming itself into his head and teasing the raw edges of his pride. “I won't
tell anyone you're all bark and no bite, Dean. Promise.”
Dean growled and threw Cas away, standing so fast he was almost dizzy before
grabbing one of Cas' arms and snatching the boy up as roughly as he'd divested
Dean of his shirt minutes earlier. A sharp yelp echoed off the tile and metal,
the sound distorted and hollow. He hooked his fingers into the waistband of
Cas' trunks and shoved them down, smiling when he heard Cas hiss as his nails
dug into the soft skin under the fabric.
He slung one arm around Cas' upper back and brought their chests flush
together, his other hand flew around and landed sharply on the plump meat of
Cas' cheeks. Cas squirmed when Dean spanked him, clutching to Dean's shoulders
frantically. Seven slaps in quick succession rang out and bounced around the
bare walls, combining beautifully with Cas' little cries.
Dean ran his hand over the blooming redness on Cas' ass, moaning softly as Cas
gasped. He turned his head and spoke into Cas' ear much the same way the teen
had spoken to him. “That enough bite for you, Cas?”
A shaky chuckle shook the chest pressed to his. Cas' head lolled back, face
dazed enough to look almost drunk or drugged. “Fuck me and we'll find out.”
Dean shoved Cas against the cold tile wall and grabbed his cock, squeezing hard
enough that Cas grimaced even as he pushed into it. “Stay, pretty boy.”
“Not your fucking pretty boy.” The words were spat back in his face, but Dean
just laughed and patted Cas' cheek, a smudge of precome left behind.
The office in the back of the locker room had what he needed stashed in one of
the lower drawers. He pulled it open and grinned, the condom and lube just
where he'd left it. Cas had stayed where Dean told him, cock hard and flushed a
pretty shade of pink. Dean handed him the supplies and grabbed a couple towels
from the rack by the showers, throwing them onto the floor hastily. He took the
lube and condom back and gestured to the towels with his head.
“All fours.” Cas smirked and did as he was told, going to his knees and elbows,
legs spread almost wider than the white cotton beneath him. He cast a look back
at Dean that spelled trouble.
Dean shoved his own trunks off and kicked them away, both of them finally
completely naked. He knelt behind Cas and kneaded the flesh of his ass, hand
fitting perfectly onto a bright red print. Cas tilted his hips back, cheeks
spreading with the motion. His pretty hole was on display, ready for Dean to
open wide and fuck raw. A couple drops of lube slid off his fingers and onto
the towel, another hit the edge of Cas' hole and Dean swirled it around with
the pad of his finger.
A little sigh left Cas' mouth when Dean pushed his finger just inside and
twirled it. “You like havin' stuff in this tight little hole, don't you?”
Cas groaned as Dean slid his finger further in, obviously used to relaxing into
similar touches. “Not as much as you'll like being in it.”
Dean wanted to fuck the smug tone right out of Cas' voice. His finger was
swallowed up, pulled in and taken greedily. And yeah, Cas was right, he wanted
in. Two fingers slid in next, and Cas started moving his hips with it, tilting
and swiveling until Dean hit the right spot. A little bump under his fingers,
Cas' prostate. Dean pushed down on it and rubbed it, smiling when the front
half of Cas' body dropped further and he whimpered at the sensation.
Thirty solid seconds of it and Dean reached down for Cas' cock with his other
hand, stroking slowly and palming the head as he eased a third finger in. Cas
tore at the towel beneath him, hips swaying into both of Dean's touches. Then
his spine bowed, mouth opening on a rough shout as he came, cock pulsing and
hole clamping down on Dean's fingers. Dean pulled them out, chucking at Cas'
keening. He rubbed up and down Cas' thighs, calming the trembling.
“Not a big deal, Cas, you're only seventeen. Happens to kids your age all the
time.” The teen stopped and took a deep breath, pushing himself up to his hands
and turning his head to look back.
There was a hard edge to his gaze that made Dean freeze, remembering the way it
seemed Cas silently promised he wasn't really in charge here. “Wrap your cock
up and get it in me now, Dean.”
He didn't need to be told twice. Cas went back to his elbows and Dean's fingers
were shaking as he tore the foil open and slipped the condom on. His head was
spinning with how quickly power had flipped again, Cas literally ordering him
to get inside. More lube was applied and Dean made sure he could slip three
fingers in easily. He would have done more, but Cas growled and glared at him.
Cas' hole pulled him in just like his fingers, the heat a slick glide that
squeezed him and claimed him. When he was fully seated he waited for a moment,
breathing deeply while Cas did the same.
After a moment Cas shifted back, grinding his hips in a slow circle that made
them both moan. Dean splayed his hands wide over Cas' hips and pulled out,
hauling Cas back in as he snapped forward roughly. It was dirty and fast, skin
slapping skin and irritating the marks already left by his hands. He thought
maybe Cas would break, that the hard face he'd put on would crumble and power
would shift back. But no. Cas gave as good as he got and demanded more.
“Dean, you've smacked my ass harder than you're fucking it.” The towels slid
forward, tiles digging into their knees. Dean grabbed Cas' shoulder and pulled
him back up, using it for added leverage. The new angle seemed to work for Cas,
his dark head of hair falling forward as he groaned and kept egging Dean on.
“Mm, more, Dean. To where I can feel it, come on.”
Dean grunted and thrust forward as he pulled Cas back, keeping them there as he
rolled his hips and pushed as deep as he could go. Cas groaned deeply and
reached back at Dean, flailing for a moment until he found Dean's thigh. A
second later Cas pulled himself free of Dean's hands and cock and Dean had a
split second to panic before Cas laid down on his back, drawing his legs to his
chest.
He smirked up at Dean, his cock starting to fill out once more. “Looks like
I'll have to lay on my back like a girl for you to fuck me like a man.”
Dean ground his jaw and squirted more lube into Cas' hole, hauling the boy in
by his hips until his knees were hooked over Dean's shoulders. “Do you ever
shut up?”
Cas smiled at him, eyes fluttering as Dean slid back home. “Not if I'm enjoying
myself.”
Dean huffed and nipped at the inside of Cas' left knee, looking at him
sidelong. His tone dripped with sarcasm, voice rougher than usual. “What a
relief.”
A scathing response was at the ready, but Dean cut it off by starting up again.
Cas moved into every thrust, one hand reaching down to grab Dean's ass. Thin
fingers dug into him, groped him as he pitched forward and almost bent Cas in
half. A broken noise punched its way out of Cas' throat, his free hand wrapping
around his cock.
“Fuck, Dean, finally.” Dean kept his hold on Cas' thighs, his already jarring
rhythm only getting harder.
The chlorine chill of the locker room was a sharp contrast to the heavy heat
building up at the bottom of Dean's spine. It fanned out and filled him as his
hands wandered up higher, nails biting in just above Cas' knees. Cas' eyes were
closed, his mouth open as he panted and groaned. His grip on Dean's ass was
getting tighter, the hand on his cock moving faster. It gave Dean a sick
satisfaction to know that even if Cas somehow tore power and control away from
him, making him enjoy the sharp tongue and tight ass, that Dean was going to
make him come twice just like the horny little slut of a teen he was.
“I'm, I'm—fuck, Dean!” Cas' pretty blue eyes shot open, face shifting into
something almost helpless and innocent looking before he came again. His ass
clamped down hard, squeezing Dean's cock as he painted his stomach in sticky
white.
That was all Dean could take, tension snapping out and pouring from him into
the condom as he came with a low moan. Their hips were flush, rolling together
because neither could get enough. Dean turned his head and sucked a dark bruise
to the inside of Cas' knee, grinning and digging his teeth in when Cas whined
and squirmed.
Cas' legs fell open and Dean fell forward, forearms bracketing the teen's
shoulders. They smiled and kissed, Dean's cock slipping free of Cas' body. The
air made them both shiver lightly as they came down.
“We should do this again.” Dean's voice was a murmur, mouth a lewd grin that
Cas mirrored.
“I told you you'd like being inside me.” Maybe next time Dean would actually
succeed in fucking the smugness out of him. Or maybe not. Either way he didn't
really mind.
