They had just finished a long case, endless days followed by near sleepless nights, both of them bruised and a little scraped, but otherwise okay. When they'd gotten back to the bunker, they'd both stripped down and climbed into Dean's bed and stayed there for the next twelve hours, asleep as soon as the sheets cleared their hips.
After waking slowly, curled closer than when they'd fallen asleep, they had lain in bed for a while, simply enjoying the quiet restfulness of being home, Sam running his fingertips in gentle patterns over Dean's skin, Dean's hand curled possessively around Sam's hip. They had reluctantly gotten up to take care of basic necessities and grabbed something to eat, but had crawled back into bed not long after.
Sam propped himself up on one arm, enjoying the sight of Dean so relaxed, sprawled under the sheets, cheeks more freckled than usual from the extended sun exposure the last few days. He reached out and stroked Dean's cheekbone, leaning in slowly to capture his lips. Dean strained up to meet him and opened up for Sam's tongue, their mouths moving slow and easy.
Keeping the pace relaxed, Sam nibbled at Dean's bottom lip and over his cheek before easing back over his lips, sealing their mouths together and lapping at every corner of his pallet. Sam's lips were tingling, a combination of Dean's kisses and the stubble sprinkling his jaw, built up from a few days without shaving. Their tongues intertwined and Dean gasped into his mouth, his hand coming up to grip the back of Sam's neck, pulling him in harder against him, hips trying to meet Sam's across the few inches separating them.
Sam soothed a hand over Dean's waist, down over his hip, gentling his brother's movements. He sucked at Dean's tongue and trailed fingertips over Dean's ribs, smiling against his mouth when his brother choked a laugh and twitched against Sam's body. Spreading his hand out over Dean's back, he pressed him closer, plundering Dean's mouth in a slow domination.
Dean met him eagerly, accepted his tongue and lips in any way Sam would give them to him. Right then, Dean was open to anything Sam wanted and Sam knew it, relished it. As Sam kissed him, nibbled at his lips and the hard line of his jaw, Dean pressed his body closer, his chest arching to meet Sam, eyes bright and eager.
Sam cupped Dean's cheek, angling his mouth for better access, running his fingers back through Dean's hair. Dean preened under the touch, so accepting and, dare Sam say needy. He loved this side of his brother.
With a light touch, Sam grazed his fingers over Dean's skin, leaving trails of goose bumps behind. He caressed the muscles of Dean's chest and his stomach, bringing his fingers back up to skim a nipple. Sam sensed a light twitch and suppressing a grin, did it again, but harder, kissing the corner of Dean's mouth as his brother moaned, nipples perking at the attention.
Sam pressed his tongue back between Dean's lips and thumbed over the now hardened nipple again, circling it and dragging his nail lightly down its center, coaxing another moaned sigh from Dean. His head dropped back leaving Sam's lips to trail down his jaw, to suck at the skin of his neck.
Dean shivered in Sam's hold, still trying to get as close to Sam as possible. Sam cradled Dean against him, flicking his thumb over the nipple again, arranging his thigh to rest against Dean's groin, his brother's cock already getting hard. He was met with a slow roll of Dean's hips and pressed in lightly with his leg. With their hips still angled towards each other, Sam pressed on Dean's shoulder, pushing him back so Sam had better access to his brother's chest.
The position may not have been the most comfortable, but it gave Dean the opportunity to get some friction and allowed Sam the chance to explore the rest of his brother's body. Sam pinched Dean's nipple between two fingers, rolling it and overwhelming Dean with pinpricks of pleasure as he sucked kisses into Dean's collarbone, his chest, and finally sucked the other nipple between his lips.
The sensations drove Dean crazy, dragged a throaty groan from him as his chest arched against Sam, his fingers biting into Sam's side. After an extended moment of sucking, Sam pulled back and blew over the nub, watching Dean's face above him, lip caught between his teeth as his eyes rolled back. Sam blew cool air over the sensitive skin again and then took it back into his mouth. Dean whimpered and tunneled his fingers into Sam's hair, pressing him harder against his chest.
It always amazed Sam how sensitive Dean's nipples were, how quickly his brother's arousal heightened when Sam so much as pinched one. With all of the attention Sam was giving them now, Dean was riding a pleasure high and Sam couldn't help the desire to finally see this through – lavish Dean's nipples with so much attention that it would push his brother into an orgasm. Sam had wanted to see if it was possible for a long time, but their pressing need for each other always got in the way. Today, the slower, easy pace they'd set seemed the perfect opportunity to finally try.
Pulling back from Dean's chest, Sam relented in teasing Dean's other nipple with his fingers as well. Dean inhaled deeply and angled his head down, seeking Sam's mouth. Sam met him eagerly but gently, sealing his lips over Dean's. For a long minute, Sam simply kissed Dean, enjoying the sweet taste of his tongue and the easy exchange between their lips.
Sam held himself over Dean's torso, his mouth still guiding Dean's in an unhurried kiss. With his free hand, Sam gripped Dean's raised hip and pushed it so his brother now lay flat on the bed, adjusting his own legs to align himself to Dean's side, hip still dipping into the mattress.
Positioned as he was with his erection just out of range of Dean's own, Sam slid his hand from Dean's hip to his cock, thumb brushing over the underside until it found the pre-come dribbling from his slit. Sam scooped it up, and drawing away from Dean's mouth, he met Dean's eyes as he took his thumb between his lips, lids falling heavy over his eyes at the taste.
Sam felt Dean's breathy sigh gust over his lips and again leaned in to kiss him. Dean gladly accepted Sam into his mouth, hand scrabbling at Sam's shoulder to pull him closer. With Dean distracted by his tongue, Sam wormed a hand between their chests and again twisted at a peaked nipple, pinching and rolling the nub until his brother gasped into his mouth and turned his head into the pillow, chest lifting and hips jerking.
Sam's cock twitched at the sight and he nibbled at the exposed edge of Dean's jaw, urging Dean's mouth back to his. His brother was flushed with arousal, eyes glittering in the dim light of the room, his plump lips swollen in the aftermath of their kisses and Sam stifled a growl at how debauched he looked.
Dean licked his bottom lip and Sam, unable to resist, claimed his mouth once more. Their tongues battled for a long moment and then Sam slowed the kiss, his thumb rubbing in repeated circles around Dean's nipple. Trailing kisses down from Dean's lips to the curve of his neck and over his collar bone, Sam released Dean's left nipple and crossed his hand under his chin, pinching its twin to a hard peak as his mouth latched on to the one he'd abandoned.
Dean arched into the touch, a whine catching in his throat, his hand again curling into Sam's hair, pulling him more firmly against his chest. Sam gladly sucked harder, sweeping his tongue over the hardened nub, nipping it lightly as he pinched the other one. Dean whined again, his hips rolling, cock hard and bobbing against his stomach, pre-come leaking from his tip.
Sam laved over Dean's nipple, alternately sucking and darting his tongue over it, dragging his teeth over the sensitive tip when Dean least expected a change in the pattern. His thumb and middle finger tweaked Dean's other nipple, his pointer flicking in quick little motions that were driving Dean insane. A near constant stream of whimpers and moans fell from Dean's lips at the sensations, his cock twitching, hips jerking, trying to find the friction that would push him over.
Sam could tell Dean was close, the familiar blush spreading over his chest and the sounds he was making a clear signal. A quiet whimper of "Sam" reached his ears as Dean's hips lifted into the air, and he realized it was the first word spoken between them since climbing back into bed that day. Dean's noises didn't stop, the pitch of them ratcheting higher the quicker Sam moved his tongue and flicked his finger. It was slightly intoxicating to know that he had driven Dean to this point.
Sam's cock ached, sore with need, but he refused to give in and ruin his chances of seeing Dean come just like this. Instead, he rocked his hips against Dean's thigh, grinding his throbbing cock and swollen balls into the meat of Dean's leg, easing some of the pressure he was feeling. It helped somewhat and he was able to focus a little more easily on pushing his brother over the edge.
Another whimper, a whine cut off in Dean's throat, hand tightening painfully in Sam's hair, and Dean was coming. Sam pulled his face away so he could see and quickly replaced his mouth with his right hand, slipping his left back over to reach Dean's other nipple. He thumbed over them both simultaneously in firm motions and watched as his brother's body seized under him, head thrown back, hips lifting and twitching into the open air, cock jerking as come spurted from his tip and fell in wet sticky streaks over his belly.
Sam ground his hips harder against Dean's thigh, continuing the motion of his thumbs on Dean's chest. Dean thrashed under him and sobbed, overwhelmed at the sensations, tears leaking down his temples as his cock spewed another stream of come.
Finally relenting, Sam pushed his left forearm under Dean's shoulder, his right hand lifting to cup Dean's cheek, pulling his brother's mouth to meet his as he rocked his hips harder. Dean was panting, more breathing against Sam's mouth than anything, but Sam sucked and lapped at his lips as he increased the pace of his thrusts. A few more and Sam too fell over the edge, forehead dropping to Dean's collarbone as his body tensed and his cock jerked, sticky come smearing over Dean's leg and dripping towards the sheets.
Dean trembled beneath him, his hands clutching at Sam's back and sides, breath still coming in short bursts. Sam pressed a gentle kiss to the skin stretched over Dean's collarbone and kissed a trail back up to Dean's mouth. He kissed over Dean's lips and then his cheeks, moving to his tear-wet temples and finally his eyelids. Dean shivered, fingers biting into Sam's back, even still trying to pull him closer.
Sam obliged him and shifted so his body rested completely over Dean's, no space between them. Dean sighed and relaxed, body settling into the mattress, humming with contentment as Sam kissed his way back to Dean's lips.
Sam kissed Dean gently, almost chastely and pulled back, stroking his thumb over Dean's cheek. Dean blinked his eyes open and stared back at Sam. "Hey," Sam whispered.
"Hey," Dean rasped back.
Sam smiled softly. "How ya feeling?"
A blissed out smile graced Dean's lips. "M' good." He shifted his hips against Sam's. "Really good."
"Yeah? You ever think you'd come just from having your nipples played with?" Sam kept his voice at a whisper, not wanting to disrupt the peaceful calm in the room.
Dean moaned, lashes fluttering. "Not even once. But damn."
Sam smiled and claimed Dean's lips again, gently coaxing his mouth open for Sam's tongue. Dean still wasn't resisting the pace he set and Sam knew they both savored times like this more than they would admit aloud. They had all day. Maybe they'd make out for hours, maybe they'd take a nap, maybe Sam would just hold Dean while they laid there in silence. Whatever they did, it would be a break from hunting, and maybe, Sam smirked against Dean's lips, he'd try to do this all over again in a little bit.
