It was late in the afternoon and Dean was contentedly sprawled on the couch in the den with Sam, a beer in hand, their shoulders pressed together, and their feet knocking against each other on the coffee table as some ridiculous crime drama played on the TV.
With all of the experience they had dealing with law enforcement and everything else on their hunts, they often spent evenings watching and critiquing various crime shows. As the episode worked up to the inevitable reveal, Dean grew more comfortable in his slouched position on the couch and gradually sank low enough that his head was even with Sam's shoulder. He rested it there, his brother's warmth seeping into his skin, and closed his eyes.
He must have dozed for a little while because Dean blinked his eyes open at feeling Sam adjust next to him, his brother pressing a tender kiss to the top of his head. Secretly, Dean smiled.
"You awake?" Sam murmured into Dean's hair.
"Mmm, yeah," Dean said through a yawn, arching his back to stretch out the tight feeling in his muscles.
"Yeah?" Dean could feel the smirk through his hair. Rather than pursue the question, Sam again kissed Dean's head and then trailed a series of kisses over his temple, his cheek, working his way to Dean's mouth. Eagerly, Dean accepted Sam's mouth against his, turning so their lips could connect more fully, a soft sound escaping his throat.
He loved kissing Sam, the heat of it, the spark that always ignited between them. He couldn't get enough and Sam knew it, took advantage of every opportunity he could get. Dean wasn't complaining and trying to ignore another of the soft happy sounds that made it out of his mouth, Dean angled his body towards Sam's, heat tingling through him as Sam's hands roamed, clutching at his back and pulling him up against him.
It was honestly insane how hot Sam got him, embarrassingly so. Dean turned with the pressure of Sam's hands against his back, settling his knees on either side of Sam's thighs, his cheeks flushing with arousal. Sam gripped Dean's hips and pulled them snugly together. Pressed as he was against Sam's chest, Dean was a full head taller than his brother and he relished the rare moment, cupping his jaw and sucking on Sam's tongue as he rocked his hips, half-hard cock caught between Sam's stomach and Dean's own.
It was like liquid fire flowing through his veins, desire and contentment and want racing through him, consuming him. Dean groaned into Sam's mouth, sucking kisses into Sam's jaw as his brother tightened his grasp on Dean's hips and pulled him in a back and forth motion against his body.
"God, Dean," Sam groaned, leaning up into Dean's kiss, thumbs circling over Dean's hipbones.
Dean shivered in Sam's hold and found Sam's mouth again, their lips connecting hot and wet and so, so good. It was electrifying feeling Sam's hands and mouth on him, feeling Sam's fingers mapping out his skin, tweaking his nipple, rocking his hips up into Dean's.
Dean broke away from Sam panting, leaning their foreheads together. He fucking loved being in Sam's lap like this. And suddenly it occurred to him. "How is it that in all the time's we've fucked, I've never ridden your cock?"
Sam reared back, startled, hazel eyes staring at Dean intently under furrowed eyebrows. "Uh–"
"No really," Dean rocked his hips, "We've switched off, we've fucked in who the fuck knows how many places, we've even done some pretty kinky shit recently. How the fuck haven't we done it like this before?"
Sam's pupils blew wide as he listened to Dean. He growled, lifting his hips clear off the couch to grind against Dean's ass, fingers digging into Dean's sides to hold him in place.
"Get to your room, now," Sam ordered, jaw rasping with stubble against Dean's cheek.
Dean sucked in a breath and stifled a groan. "Why?" All he wanted right now was more of Sam, to have Sam inside him, to ride him right here, just like this.
Sam nipped at Dean's collarbone. "No lube in here."
"Should fucking fix that," Dean managed to get out around the moan fighting to leave him.
"S' more space on the bed anyway." Dean nodded, fingers biting into Sam's shoulders, knees clutching at his hips. "C'mon," Sam urged, nudging Dean up.
Reluctantly Dean moved, getting his feet under him and pulling Sam up with him. As Dean tugged at Sam, trying to kiss him even as he stepped backwards, his brother smirked and dug his fingertips into Dean's sides, forcing a surprised huff of laughter out of him. "Dude!" He shouted, aiming a punch at Sam's ribs.
Sam curled his lips into his mouth to hide the grin threatening to spread across his face. Dean scowled, but it was more playful than angry and he again tugged at Sam to get him to move. "Move it, asshole."
Sam full on grinned at that and followed Dean as he led them to his bedroom. Having made it across the bunker and into Dean's room, Sam plastered himself to Dean's back, sucking a kiss into the side of Dean's neck. Dean groaned and dropped his head to the side, hands curled over Sam's on his hips.
"Get undressed," Sam directed, voice thick and husky, setting Dean's hair on end and shivers down his spine.
Quickly, Dean stepped out of Sam's hold and shucked his shirts, dropping them in piles across the floor as he approached the bed, belt jingling as his pants dropped too. Sam followed behind, his clothes disappearing just as hastily, and then Dean turned to face him, shoving him back on the bed and climbing on top of him.
With his hands pinning Sam's shoulders to the bed, knees on either side, Dean hovered above his brother, wicked grin quirking his lips. Swiping his tongue over his bottom lip, Dean leaned a little closer, teasing Sam by being just out of reach. "You ready to fuck me, Sammy? Ready for me to slide down on you and ride your cock?"
Sam threw his head back on the bed, hair fanning out around him, jaw tight as a groan vibrated through him. Getting Sam worked up was one of Dean's favorite things and he felt his cock twitch just watching his brother. His throat was tight with arousal and he rasped his next words. "You know I fingered myself thinking about you in the shower earlier? I'm already so open and ready for you. Fuck, Sammy."
A snarl filled the room and Sam surged under Dean's hold, forcing Dean back as he sat up. He dug his teeth into Dean's neck, reaching for the lube even as he wrapped his other arm around Dean and split his cheeks with one hand.
Dean gasped, caught off guard, and clutched at Sam's shoulders, the sudden movement offsetting his balance. It was seconds before Sam's slicked fingers dragged over his crease and Dean cupped a hand around Sam's neck, dragging him closer, his mouth harder against Dean's neck. The feeling of Sam's stubble on his skin, his teeth pressing down and the thought of Sam's mark being left on him had Dean flying high. He relished these moments of Sam's passion. His cock was throbbing, leaking between them.
As Sam distracted Dean with his sucking, biting kisses, slicked fingers approached Dean's hole and slid inside. Dean choked on a moan and pushed his hips back, startled but appreciative of the abrupt fullness.
"You weren't kidding, Dean," Sam murmured into Dean's neck, fingers sliding deeper and spreading. "You're hot and so open already, sucking me deep."
Dean clenched at the words, his hole closing eagerly around Sam's fingers.
"Fuck," Sam grunted, teeth nipping again at Deans' jugular. Without warning, he added a third digit, simply gliding it in with the others on the next thrust, twisting and scissoring and meeting hardly any resistance. "So open for me."
Dean whined at the stretch, couldn't help how his hips jerked down against Sam's hand. "M' ready, Sammy. Please, fuck, I'm ready."
Sam gave one more wide stretch to Dean's hole before retracting his fingers, soothing a hand over Dean's flank and kissing him deeply. When Dean sighed into Sam's mouth, Sam broke the kiss and leaned back on his hands.
The sight of Sam so casual, simply lying in wait for Dean to act set Dean's heart racing. His teeth sunk into his bottom lip, thighs shaking in anticipation. Getting his feet under him, Dean put a supporting hand on Sam's chest for balance and crouched over his brother's lap. Honestly, it was a bit intimidating to be completely in charge of sitting himself down on his brother's monster cock.
It was no secret between them that Dean favored bottoming, enjoyed the fullness and the stretch, so much he did it almost exclusively. This was the first time however that Sam wasn't directing his cock to Dean's hole, wasn't lining them up, wasn't the one pushing inside.
This time, it was Dean who had to do it all and it was more than he'd thought it would be. Steeling himself with a deep breath, Dean lowered his hips until he felt Sam's cockhead grazing his cheeks. Dean's tongue poked out between his teeth and fuck that was embarrassing, but he concentrated on lining Sam up with his hole and fought to keep his balance as he sank down.
Sam groaned loudly as his cockhead disappeared inside Dean's body and Dean darted a glance to Sam's face before focusing back on adjusting to the girth filling him and the awkward movement he had to make so this would work.
It felt like his knees were up by his ears, but Dean ignored the weird position and inhaled deeply. This was a new angle and already it felt a little different. Putting both hands on Sam's chest, Dean steadied himself and slowly pressed his hips down, breath hitching when Sam was balls deep inside him. Fuck, he did it.
He shot a shy smile at his brother and was pleased to see Sam biting into his bottom lip. Dean could tell Sam was fighting the urge to move. Lifting up in a small movement, Dean dropped himself back down, doing it again to adjust to the motion and Sam's girth. When he felt ready, Dean eased himself up more of Sam's length and slowly glided back down, hands gripping at Sam's shoulders for balance.
Just when Dean was starting to get a rhythm, Sam slammed his hips up as Dean was moving down. A startled groan punched out of Dean's lungs and his head dropped back, hips grinding into Sam's before he pushed himself up again.
Sam fucked up into Dean through the next few pulses of Dean's hips and when Dean asked for "harder, god, fuck – please", whipped his hips up into Dean with record speed.
It wasn't long before Sam's hips slowed and Dean was able to loosen his grip on his brother's shoulders. "Can only keep that up for so long, Dean." He explained, growling his next words. "Take what you need."
Dean whined at the directive and nodded, his eyes glassy. Already he was having trouble keeping his balance so Dean leaned back, settling his hands on Sam's thighs just above the knee. The new position sent tingles up his spine and Dean groaned.
With every intention of fucking himself silly and riding Sam as planned, he lifted his hips and drove himself down, small groans and grunts tearing out of his throat as the position drove Sam's cock deep into his body and grazed his prostate. He couldn't get enough and it was clear Sam couldn't either. His brother's hips twitched up as Dean dropped down onto his cock, his stomach muscles rippling with the small movements.
After a few minutes of unrestrained fucking, Dean's thighs ached with the strain of constant motion, calves burning. The burn was becoming too much and he wouldn't be able to finish if he stayed like that. "Gotta move," he mumbled, leveraging himself to crouch over Sam on the bed.
Sam simply gazed up at him, eyes blown with lust and cock bobbing for Dean's attention. Swallowing heavily, Dean settled onto his knees and felt Sam's wet tip graze his ass. Dean reached behind him and lined Sam up again with his hole.
Dean sank down and sucked in a breath as he was filled once more. He couldn't quite get the same leverage, the movement less fluid having to push up from his knees, but it worked well enough. He dropped down and lifted himself up Sam's length a few times, the stretch so good Dean shook with it.
It wasn't enough though, the motion too different to give him what he needed. Without the speed he was able to get before bouncing on Sam's cock, Dean needed to try something different. Huffing air through his nose, Dean gripped Sam's shoulders and pressed himself down, sinking until Sam was fully inside him. He breathed deeply.
Teeth denting his bottom lip, Dean rotated his hips, breath hitching and escaping in a stifled whimper. He continued the motion, grinding himself onto Sam's cock, lashes fluttering over his cheeks at the feeling of pure bliss, his hole now constantly full, just the pressure changing to drive him insane. Sam's cock was hitting his prostate on every rotation, so deep inside him, thick and pressing an imprint into Dean's body.
The pleasure was so intense Dean had to back off slightly, instead rocking his hips forward and back to change the angle, Sam's cock gliding only partway out before Dean's body engulfed it again.
The intensity eased some and Dean didn't feel like he was seconds away from coming. Even still, the sensations were overwhelming and he choked off a whine.
Dean panted and tucked his face into Sam's neck, one arm thrown over Sam's shoulder, the other clutching at his nape. He couldn't get Sam close enough, would never get enough of feeling this good.
Sam kept one arm extended behind him, supporting the weight of their bodies, the other coming up around Dean's hip. The sensations were making Dean crazy and he was losing his rhythm, but Sam used the hold to come to the rescue and helped guide his movements.
With Sam taking some of the control, easing Dean into a smoother rhythm, Dean could feel the pleasure mounting, heat simmering in his belly and building to a boiling point. Dean dropped one hand between their bodies to cup his cock, pressing it against his belly before finally taking it in hand and giving it a jerk.
He sighed at the increase in pleasure, breath hitching and tumbling from his lips in keening bursts. Pre-come dribbled down his shaft, his slit bubbling with it and his balls so full, Dean knew it wouldn't be long before he came.
The heat steadily built and when Dean couldn't take anymore, he gasped, "Sammy!"
"That's it, Dean," Sam crooned, still guiding Dean's hips, fingers rubbing soothing circles into the skin beneath them. Dean whined a high-pitched needy sound, and unable to hold off any longer, tumbled over the edge, body trembling in Sam's hold, hips jerking uncontrollably as his cock spattered his and Sam's abs. His hand fell to Sam's waist and he simply held on as he fell apart.
Sam shuddered and shoved his hips up, tensing as he too came, spilling deep inside Dean's body. Dean growled at the burst of heat and collapsed against Sam's chest, pressing slow wet kisses to Sam's shoulder and the skin of his neck.
As they both came down, Sam curled his arm tighter around Dean's hips and simply held him close. Dean squirmed lightly in Sam's lap, his brother's cock still splitting him open, now with the addition of hot come painting his insides. It was a strange feeling, though not unfamiliar; he simply never got used to it.
He winced as Sam softened enough to slip free, his hole feeling suddenly too open and empty, a trickle of Sam's come leaking out making him feel vaguely dirty. As their breathing evened, Sam dropped flat to the bed, pulling Dean down on top of him.
Dean settled into Sam's chest, content to lay with him and just feel the effects of having ridden his brother's cock. His thighs were still burning, his hips achy from the new movements, but he felt so satisfied, it was all worth it. Dean hummed a sigh and closed his eyes.
The rumble of Sam's voice made his eyes slit open. "Feel better now that you got to ride me?"
"Mmmm," Dean murmured, lips turning up tiredly at the corners, "was good."
"Yeah, it was." Sam rubbed a hand over Dean's back. "You gonna want to do it again?"
"Fuck yes," Dean confirmed, rocking his hips down against Sam's. "Just – not now. My thighs are fucking burning, man."
Dean felt Sam's chest vibrate with the laughter that echoed into the room. Dean grinned.
