Jake slammed the door behind him after a long day at the construction site, sweat still clinging to his broad chest. His younger brother Ryan was already home from college, sprawled on the couch in nothing but loose shorts. At 25 and 23, they had the house to themselves for the weekend while their parents were gone. Jake's eyes locked on Ryan's lean body, the way his shorts rode up to show the outline of his dick.
"Quit staring, asshole," Ryan said, but his voice had that teasing edge they both knew too well.
Jake didn't bother with small talk. He crossed the room, grabbed Ryan by the hair, and pulled him into a rough kiss. Tongues slid together hard and wet. "Been thinking about this all week," Jake growled against his brother's mouth. "Your tight ass needs my cock again."
Ryan shoved his hand down Jake's jeans, gripping the thick shaft already hard and leaking. "Then stop talking and fuck me like you mean it."
They stripped fast, clothes hitting the floor. Jake pushed Ryan onto his knees right there in the living room. Ryan opened wide and took his brother's fat cock to the back of his throat in one go. Jake fucked his face in short, dirty thrusts, balls slapping against Ryan's chin. Spit ran down Ryan's neck as he gagged and moaned around the meat stretching his mouth.
"Fuck yeah, suck that brother cock," Jake grunted. He pulled out and hauled Ryan up, bending him over the arm of the couch. Jake spat on his fingers and shoved two straight into Ryan's hole, working it open fast and rough. Ryan pushed back, begging for more. "Deeper, Jake. Stretch my fucking ass."
Jake lined up and drove in balls-deep with one thrust. Ryan yelled out, half pain, half pleasure, as his brother's thick dick filled him. Jake didn't wait. He pounded hard from the start, hips slapping against Ryan's ass with loud, wet smacks. Every stroke bottomed out, grinding against that spot that made Ryan's own cock drip onto the couch.
They switched positions on the floor. Ryan rode Jake reverse, slamming down on the cock while Jake reached around to jerk him off. "That's it, ride your big brother's dick," Jake ordered, slapping Ryan's ass red. Ryan bounced faster, hole clenching tight, until Jake flipped them again and fucked him missionary. He held Ryan's legs wide and hammered in, staring down at his brother's flushed face.
"Fill me up," Ryan demanded. "Shoot that load in my ass."
Jake came first with a low growl, pumping thick ropes deep inside Ryan's hole. He kept thrusting through it, pushing the cum deeper.

Ryan stroked himself fast and shot across his own stomach, hole pulsing around Jake's still-hard cock.
They stayed locked together on the floor, breathing heavy, sweat mixing. Jake pulled out slow and watched his cum leak from Ryan's used ass. Ryan grinned up at him. "Round two in the shower?"
Jake hauled him up by the arm. "Yeah. And this time I'm fucking your throat till you swallow every drop."
They moved to the bathroom, water running hot. Jake pressed Ryan against the tiles and fed him his cock again, already stiffening back up from the sight of his brother's cum-slick hole. Ryan sucked greedily, taking it all while Jake held his head and used his mouth. When Jake came down his throat, Ryan swallowed without spilling a drop, then stood and bent over the sink for another round.
Jake slid back inside the sloppy, cum-filled ass and fucked him steady and deep until Ryan came again, untouched, his load splattering the sink. They cleaned up just enough to stumble to the bedroom, where they crashed together, bodies still tangled. Jake's hand rested possessively on Ryan's ass as they drifted off, already planning the next morning's wake-up fuck.
The weekend stretched ahead with nothing but more raw, brother-on-brother action. No rules, just the dirty need they both shared.
