Jake slammed the door behind him, the summer heat still clinging to his skin. At nineteen he was home from his first year of college, and the house felt too quiet with just him and his little brother. Mike was eighteen now, tall and lean from the gym, sprawled on the couch in nothing but gray boxers that left nothing to the imagination.
“Mom and Dad are gone till Tuesday,” Mike said, not looking up from his phone. “We got the place.”
Jake dropped his bag and stared. He had spent the whole semester trying not to think about his brother’s body, the way Mike’s ass looked when he bent over, the thick outline of his cock when he got hard in the mornings. Now they were alone.
Mike finally glanced up. “You keep staring at my dick like you want to suck it.”
The words hit like a slap. Jake’s own cock twitched hard in his jeans. “Shut the fuck up.”
Mike grinned, slow and dirty. “Make me.”
Jake crossed the room in three steps. He grabbed Mike by the hair and yanked his head back. “You been wanting this, little brother?”
Mike’s boxers tented instantly. “Yeah. Since I was old enough to jerk off thinking about you.”
Jake shoved his tongue down Mike’s throat, kissing him rough and wet. Mike moaned into it, hands already yanking at Jake’s belt. The second Jake’s cock sprang free, Mike wrapped his fist around it and stroked hard.
“Fuck, it’s bigger than I remember,” Mike growled. He dropped to his knees right there on the living room floor and swallowed Jake to the root.
Jake’s head fell back. “Goddamn, take it all, you nasty little fuck.”
Mike gagged but didn’t pull off, throat working, spit dripping down Jake’s balls. He sucked like he’d been practicing, noisy and sloppy, one hand jerking the base while his tongue swirled under the head.
Jake fucked his face for a minute, then hauled him up and bent him over the couch arm. He ripped the boxers down, spread Mike’s cheeks, and spit on his hole.
“Gonna wreck this ass,” Jake said, lining up. “You ready for your big brother’s cock?”
“Do it,” Mike panted. “Fuck me raw.”
Jake pushed in slow, letting Mike feel every thick inch stretch him open. Mike’s hole clenched and fluttered, taking it like he was made for it. Once Jake bottomed out he started pounding, hips slapping loud and filthy.
“Fuck, fuck, fuck,” Mike chanted, pushing back to meet every thrust. “Harder, Jake. Breed your little brother.”
Jake reached around and fisted Mike’s leaking cock, jerking him in time with the brutal thrusts. The couch creaked. Sweat slicked their skin. Jake leaned down and bit the back of Mike’s neck, marking him.
They switched positions twice—Mike riding him on the floor, then Jake pinning him face-down on the carpet, drilling him deep until Mike’s hole was puffy and red. When Jake finally unloaded, he stayed buried, pumping pulse after pulse of thick cum into his brother’s guts.
Mike came untouched, shooting ropes across the rug with a broken moan.
They lay there breathing hard, Jake still inside him. Mike reached back and pulled Jake’s hand to his mouth, sucking the fingers clean.
“Round two in the shower?” Mike asked, voice hoarse.
Jake’s cock gave a tired twitch. “Yeah. Then I’m putting another load down your throat.”
Mike grinned against the floor. “Good. We got all weekend, big brother.”
