Part 4

Sam breathed into the air between them, static with frustration and all the hard coils of want curling in their bodies, all of this for each other.

The silence was almost suffocating, Sam could feel the panic well up in him. The almost terror of what he just said hurtling towards him like a freight train. But Dean's eye's turned black, glassy and so dark with lust that Sam felt a moan rise in his throat.

Dean's hands pulled his hips forward and Dean's upper torso rushed upwards, nearly knocking Sam back, he could feel Dean's tongue thrust into his mouth, Sam moaned so hard he thought he could feel the vibrations in Dean's chest as he felt spit and tongue fuck his mouth.

Feeling Dean's hands spread his cheeks apart in his jeans, Sam could feel his body was on fire, cock hard and moist in Dean's boxers, sucking on his brothers tongue.

Pulling away with lungs desperate for oxygen but swollen lips glistening and cocks hard in their jeans for what Sam just asked for.

Dean peeled his hands out of Sam's jeans, palms hot and itching to wander over Sam, but if they're going to do this he'll be damned if their going to do it in the front room smelling like pizza grease and forgotten beer bottles on an abandoned sofa.

Sam protested with a certain pathetic whimper, breaking Dean into a soft smile his heart swelling so hard he thought if he looked to long at Sam there, flushed and lips wet with his spit he would explode.

"C'mon Sammy, thought you had more class then doin' it on a crappy sofa." Dean breathed softly against his lips, half kisses and intakes of oxygen against Sam's tingling bottom lip, but ever inch of his skin was tingling and thrumming with quick thought of what they were about to do.

Dean was the first to lean up, pushing his hands behind him to leaver the heavy weight of them both into a semi leaning position, the couch arm digging hard and dull into the middle of his back.

The both managed to climb onto the floor with uncomfortable grunts and hazy lust smiles, Dean just pulled Sam against him and kissed him, softer this time. Curling his tongue and sucking with a certain experience.

Feeling Sam melt into him, Sam had an inch on Dean but he could feel Sam try and blend into him, force his naked chest against him and wrap his long arms around Dean's wide shoulders trying not to let his knees fail him as they stood learning each others mouths.

But Sam soon collected himself, Dean's mouth chasing forward to continue their kiss but Sam just gripped his wrist, hot and tight in his slender fingers and lead him to their room, the house was dark and the walk seemed too long and silent except for their breathing filling the shadows that bent the empty rooms.

The shafts of moonlight that ghostly gray light, twisting the paper scattered desk Sam worked on and the pile of dirty clothes that lent against the cool colorless wall. The floor almost looking like a tar pool and the bed sheets straight and white in the slanting moonlight.

And Dean didn't notice when Sam lost his rucked shirt but it was gone and miles of what he knew was golden skin was stretched gray and rippling. He didn't even know how Sam had managed to crawl in to the middle of the bed, sat like he was bathing in the eerie light, just a shadow of his blush curving on his cheek bones and staining his filling out chest.

His hand was stretched out inviting Dean to bath with him, in him if Dean could manage not to be swept by what he thought was pure beauty, and the walk, the crawl onto their bed was nearly as painful against the clawing want to just melt into Sam.

The words they both wanted to say were stuck, but it didn't matter. They were here and they were going to do this and it made Dean smile softly, pressing butterfly kisses against Sam's craving lips.

He didn't want to rush any of this, finally sealing his lips to Sam's pushing into the warmth he knew so well as he pushed them down onto the cool sheets, so ruff against Sam's sensitized skin as he mewed into Dean's mouth.

But Sam was impatient, he couldn't take this, waiting he'd being doing for as long as he could remember. It had all started out as wanting to be Dean but it had shifted along the way, along the never ending roads and the faceless motel rooms, against the over starched sheets and the leather backseat to wanting Dean.

Dean could feel Sam's fingers, shaky and clumsy at the hem of his shirt, clawing at the soft skin of his stomach, bitten nails scrapping dull as he pulled it up, past his belly button and above Dean's nipples.

Dean broke the kiss, sitting with a difficult heave onto his haunches, tugging hard and fast, scrapping the hem against his lips and nose before he threw it into an unknown corner of the room, pressing himself down and flush against the hot skin of his brother.

Sam couldn't help as a moan broke in the wobbling silence, only punctured by their sharp gasps and soft groans, Dean tried to braise himself, it was a valiant effort but Sam's fingers skittered and mouth sucked against his hammering pulse, it's just to much and not enough.

Burying his face into the curve that connected the long curve of Sam's neck and wide shoulders as he felt Sam's fingertips trip over the brass of his jean button. Scrabbling and frustrated whimpers pressed into his cropped hair only drove Dean's hands to help.

Batting away Sam's hands with an experience Sam had to listen to the hiss of the zip fill the silence. Groaning despite himself, relishing the blissful release from the almost bondage of his jeans but Sam's bitten off moans of pure need knocked him back into the task at hand.

Sam was so uncoordinated, limbs slippery with sweat and hands clumsy with the need that burnt through his body.

"De-please-I can't!" Sam whined, panting and desperate for release as he pushed against his jeans frustratingly.

"Easy Sammy" Dean could only breathe as he cupped Sam's fidgeting fingertips in his hands, leaning down to Sam's hands in his own, placing kisses and sucking on his fingertips.

Sam's moans broke into the air as he stared down into Dean's eyes, glassy and black with need, when Dean pulled the button open and pulled down the button, seeing the damp clothe that outlined Sam's aching cock.

Hooking his thumbs into the waist band of the boxers, Sam lifted his hips, propping up onto his elbows, looking through wet bangs as the clothing slipped past his sweat gilded thighs.

Dean pulled hard and quick when he felt Sam's jeans and underwear hook at his ankles, throwing them away as he shimmed out of his own, feeling the cool air brush against the back of his thighs.

Dean balanced himself over Sam as he rummaged in the oaken bedside table, pulling the draw out with a frustrated tug, sweeping his hands through the debris of paper, pens and what he had to double take as a hair pin.

His smirk bloomed when his hand gripped round the half empty KY tube, tossing it onto Sam's chest, Sam yelped at the cool metal tube as Dean continued to fish round the draw.

The only part of his mind that wasn't goo was trying to concentrate on where a condom should have being. It wasn't that their relationship was exclusive. Sam and him were still into girls and on a number of occasions Sam had brought a little girlfriend or two round and Dean had still hit the bars when he could for some tail.

But the frustration was starting to boil over and as his fingers his the corners of the draw he lost it and pulled the whole thing out, spilling the contense with a thud onto the bedroom floor.

"What's wrong?" Sam asked with a small pant, propping himself onto his elbows as Dean crawled onto the floor. Spreading the crap int the draw across the floor.

"Fuck! I thought I put one in here" Dean huffed as he moved over to his discarded jeans, digging his hands into the pockets.

Something clicked in Sam's fogged mind as Dean began to pull out the other draws of the room, growling with a frustrated huff.

"You better be shitting me Dean, you're kidding me right?" Sam asked as he sat up straight and to attention.

"No, I can't fucking find it. You know we could-"

"No fucking way Dean! I love you but we are not doing this without protection!" Sam crossed his arms over his flushed chest.

"Fuck! Hey fucking hold on a second I think I know where there is a box! I'm so awesome." Dean said with a self satisfied smirk, swaggering over to Sam and pulling him into a deep, slow kiss.

It was awkward going as he pulled on a pair of boxers over his erection and left his very naked, very hard little brother in their bedroom.

The rooms were cold and the T.V was still on, Late night infomercials boasting shitty products, with bottle blonds leaning over with fake breasts at jewelry that would your skin green after a day.

Dean pulled open the duffel bags side pocket with a happy grin, noticing the battered black box of Trojans staring up at him, he managed to pull out another tube of lube when the door opened and the harsh wind blasted through the room.

"Dad!" Dean yelped as he dropped the box and lube onto the floor in front of him, hands shooting down to cover his erection as he stared wide eyed at his father in the doorway.

"Oh..Hey..Um..Did I catch you at a bad time?" John asked with a amused smirk as he stared at his oldest son, half naked and eyes wider then a dear caught in headlights.

John was sort of pleased, Dean never brought girls to the house and thought Dean had finally got a little serious with someone instead of the easies he had in bars and diners.

"Um..Yeah kinda Dad. You wouldn't mind you know-Being away for a night would you?" Dean tried to stop the panic hitting him like a ton of bricks as his heart jumped into his throat.

"No problem son, just ha make sure you clean the sheets." John joked as he clapped his Dean on the shoulder.

"Yeah course!" Dean played along, trying not to cringe as his Father's hand landed on his shoulder, cold and heavy.

"By the way, where's Sammy?" John asked before he turned to leave, the strong scent of whiskey on his breath and his body more relaxed then it always was.

"Oh he's um-he's at a buddy's house- studying and shit. You know what geek boys like!" Dean laughed nervously, trying is hardest not to freak or blurt "Would you fuck off old man!" His smile faltering a little with nerves.

"Yeah he's a good kid, I'll uh I'll be the Dew Drop Motel if ya need me." John said as he turned to leave.

"Dean! What the fuck is taking so lo- Oh my God-Dad!"
