The house was dead quiet after midnight when Jake slipped into his older brother’s room. Mark was twenty-four, built like a linebacker, and already half-hard under the thin sheet. Jake was twenty-one, horny as hell, and done pretending he didn’t want exactly this.
“Lock the door,” Mark said, voice low and rough. Jake turned the lock, heart pounding. No more sneaking glances in the shower. No more jerking off to the memory of Mark’s thick cock swinging between his legs.
Tonight they were doing it for real.
Mark shoved the sheet down. His cock stood straight up, fat and veined, the head already shiny. “Get over here and suck it.”
Jake dropped to his knees at the edge of the bed. He wrapped both hands around his brother’s dick and licked the slit first, tasting the salt. Mark groaned and grabbed a fistful of Jake’s hair. “That’s it. Open wide.”
Jake took the head into his mouth and sucked hard. Mark’s hips pushed up, driving more of that heavy cock down his throat. Jake gagged once, spit running down the shaft, but he didn’t pull back. He wanted it all. Mark fucked his face in short, dirty thrusts, balls slapping Jake’s chin.
“Fuck, little brother, your mouth is so fucking good,” Mark growled. He pulled Jake off his cock with a wet pop and hauled him onto the bed. “Strip. Now.”
Clothes hit the floor. Jake’s own cock was leaking against his stomach. Mark shoved him onto his back, spread his legs, and spit on his hole. Two thick fingers pushed inside without warning. Jake hissed at the burn but pushed down onto them.
“Gonna open you up,” Mark said, scissoring his fingers. “Then I’m gonna fuck you raw. You want your big brother’s load in your ass?”
“Yes,” Jake panted. “Fuck me, Mark. Fill me up.”
Mark pulled his fingers out, lined up that fat cock, and pushed. The stretch was brutal. Jake’s hole burned and clenched, but Mark kept sinking in, inch after thick inch, until his balls rested against Jake’s ass. They both groaned at the same time.
Mark started fucking him hard from the first stroke. The bed creaked. Skin slapped. Jake reached down and jerked his own cock in time with the pounding. Every thrust dragged over his prostate and made his toes curl.
“Harder,” Jake begged. “Fuck me like you mean it.”
Mark flipped him onto his stomach, yanked his hips up, and slammed back in. One hand pressed Jake’s face into the mattress while the other gripped his hip hard enough to bruise. The angle was deeper now. Jake could feel every ridge of his brother’s cock stretching him open.
“Gonna cum in this tight hole,” Mark grunted. “Gonna breed my little brother.”
Jake came first, shooting across the sheets with a broken moan. His ass clamped down around Mark’s cock. Mark swore, buried himself to the hilt, and pumped hot, thick pulses of cum deep inside him. Jake felt every spurt, felt it leaking out around the shaft when Mark kept thrusting through the aftershocks.
They stayed locked together, breathing hard. Mark’s cock softened but stayed inside. He leaned down and bit the back of Jake’s neck.
“Round two in ten minutes,” he muttered. “This time I want you riding me.”
Jake pushed back against him, already getting hard again. “Door’s still locked. We’ve got all night.”
Mark’s low laugh vibrated through both of them. “Good. Because I’m not done using this ass until the sun comes up.”
