two ficlets for this prompt behind the cut

The sunscreen makes Sam’s hips slick underneath his fingers so Dean has to dig in with his fingertips a little deeper, a little harder, and when it doesn’t give him the purchase he needs he grips the back of Sam’s neck instead, holding him down as Sam makes punched-out breathy noises; his mouth is open as he gasps so Dean hooks a finger in past his lips and it has to taste like the lotion but Sam closes his mouth around it, anyway.  The concrete of the pool deck is rubbing his knees raw and it has to be doing the same to Sam’s but neither of them stop.

It’s been building up for at least a week, neither one of them giving in because it’s always been like this between them, pushing and pulling and seeing who admits defeat.  Sam had started it when they found the empty house, stripping down to his boxers because neither one of them owns a swimsuit and jumping straight into the pool, coming out with water dripping off his long limbs and the tips of his hair and grinning at Dean smug and sure, like Dean’s a sure thing, so Dean had gone and laid down on a pool chair and ignored him.

And it’s been like that for days, Sam showing off his slim body, rubbing suntan lotion he doesn’t need into the concave of his stomach and the long planes of his chest, wet boxers sticking to his slimly muscled thighs, while Dean lay on the pool chair and burned in blotchy patches over his shoulders and back and tried not to watch.

He’s not sure which one of them snapped first but he’s gonna count it as a win because it had been Sam who touched him first, Sam who came up behind him while he was sleeping and run a hand slick with sunscreen down his red back, murmuring, “You’re burned, you moron.”

Dean had stretched lazily, arms flung out over his head, half-hard cock pressed into the slats of the pool chair, and said, “Help me out, then.”

And it had gone from there like Dean knew it would ever since they found the empty house and the pool, Sam straddling his hips and rubbing the lotion gently into his sun-crisp shoulders, kneeling up to let Dean turn onto his back; the plastic slats of the chair had hurt digging into his burned skin but Sam had lowered himself back down so that his weight pressed against Dean’s hard cock and Dean had forgotten the pain immediately.  Sam had sucked in a little wounded breath when Dean slid his hand inside Sam’s boxers, gripping the tight hot flesh of Sam’s dick, rubbing the wetness around the head.  It’d been worth the sunburn to listen to the way Sam whined as he kneeled above Dean and pressed his fingers slick with the suntan lotion inside himself, hips twitching as he fucked himself on his fingers, Dean gripping his hips to steady him.

“Tease,” Dean had gritted out, watching the slick glide of Sam’ fingers, “you filthy fucking tease,” and he’d wanted to fuck Sam right there, watch Sam ride him with uncoordinated jerks of his hips, but the pool chair felt like it was going to collapse under their weight so he’d shoved at Sam’s shoulders.

So now he’s got Sam underneath him, smooth tanned skin pliant under his fingers as he fucks into Sam lazily, slowly.  “Faster,” Sam gasps but Dean ignores him, and on his next thrust he pushes in so slow that Sam’s breath explodes out of him and his arms start shaking; when Dean slams into him with sudden force he falls to his elbows and Dean follows him, plastering himself over Sam’s hot sweaty back and fucking him with short hard jerks of his hips. 

“Don’t,” Dean says, breathless, sneaking a hand underneath Sam’s body and finding his cock slick, jerking Sam fast and ruthless, “don’t fucking tease me, Sammy,” and Sam comes with a long bitten-off moan.  He’s loose and pliant, shivering, when Dean flips him over onto his back and fucks him so hard that he has to brace his palms on the ground for purchase.

Sam jumps in the pool naked afterward to wash off the come and the sweat and floats on his back, staring up at Dean where he stands on the edge of the pool.

“I like this place,” Sam says, and closes his eyes against the glare of the sun.  “Let’s stay here for a while.”

“Dean”, Sam pants, “Dean, please”.

“Teases get teased, Sammy. You should’ve known better.”

Dean speeds up his fingers anyway, determined to get back at his little brother. Not even a week has passed since Dad left them at this house, rationalizing the lack of A/C with the pool in the backyard, and already Sam has been driven him up the wall. The little shit has been taunting Dean all week, all his golden skin on display. Never bothering with a shirt, and wearing sinfully tight and too-small swim trunks out by the pool, skin tanning after just minutes in the sun. It wasn’t until he caught Sam staring at his naked torso that he realized what was happening. From there it was easy to corner Sam in his room, back him up against a wall and force him to admit what he wanted, kiss him breathless and toss him onto the bed.

“You still with me, bro?”

Dean shakes himself, Sam’s peering at him over his shoulder, hips working back onto his fingers. “Yeah, just thinking about how pretty you’re gonna look stretched out on my dick”. Sam flicks his leg up and kicks him in the back of the thigh with his heel, “Get in me already”.

He slicks himself quick and pushes in in one long thrust.

It’s tight. So tight.  Squeezing him impossibly good, he tilts his hips and watches his cock slide in further, Sam’s body parting for him easily, and god, he has to look away, the visual of his hard cock disappearing into Sam’s body too much for him to handle. He smoothes a hand along Sam’s spine, sunbronzed and still glistening with sweat. “Dean”, Sam shoves his hips back into Dean’s, “come on”. Dean fits himself around Sam’s frame and gives a tentative thrust. “‘M not gonna break.” Sam mumbles. “Give it to me.” And really, Dean can’t let that sort of challenge go un-met.

He slams forward, knocking Sam off his balance and tipping him onto his chest, face pressed into the sheets, and starts hammering. Sam lets out a choked-off moan and pushes back into it, hips meeting Dean’s with every thrust. “Gonna make you feel so good, little brother.” He twists his hips, trying different angles until Sam just about screams and jackknifes, and then pounds that spot. Their hips slam together and its perfect, burning hot, an inferno around his cock and he never wants this to end. But he can hear Sam’s moans getting higher, more and more distressed, and he fumbles a hand around to Sam’s dick, tugs, and immediately Sam seizes up, clenching around Dean’s cock, come spurting against the sheets.

Dean follows, his orgasm wrenching out of him in slow, sweet pulls, unable to withstand the pulsing clench of Sam’s hole; he feels like he’s shooting his brain out of his dick. He collapses against Sam’s back, knees wobbly and arms threatening to give. They rearrange themselves on the bed, laughing a little at the uncomfortableness that comes from being half in the wet spot, come squishing between them.

“Shoulda just said somethin’, Sammy. Coulda been doing this for ages.”

“Yeah, ok Dean, like ‘Hey brother I want you to fuck me senseless’ would’ve gone over well.”

Dean sticks his come-covered hand in Sam’s face just to hear him splutter and tells him to shut-up.
