Jake slammed the door behind him, his cock already throbbing in his jeans as he spotted his younger brother Ryan sprawled on the couch in nothing but boxers. "Get your ass in the bedroom, now," Jake growled, voice rough and low. Ryan looked up, eyes dark with the same hunger they'd been feeding for months. He stood without a word, dropping the boxers as he walked, his smooth ass flexing with each step. Jake followed, yanking his shirt off and freeing his thick nine-inch cock, already leaking.
Ryan bent over the bed the second he reached it, spreading his cheeks. "Fuck me raw, big brother. Fill me till I can't take it." Jake didn't hesitate. He spat on Ryan's hole, rubbed his cockhead against the tight ring, then shoved in balls-deep in one thrust. Ryan grunted, pushing back. "Yeah, stretch that brother hole." Jake pounded him hard, hips slapping skin, balls swinging and smacking Ryan's taint. Sweat dripped down Jake's chest as he gripped Ryan's hips, driving deeper with every stroke.
"Take it, you filthy fuck," Jake snarled, pulling almost all the way out before slamming back in. Ryan moaned loud, his own cock dripping onto the sheets. Jake's pace turned brutal, the bed creaking under them. He reached around and jerked Ryan's cock in time with his thrusts. "Gonna pump you full, little bro. Gonna make that gut swell with my cum." The dirty talk pushed them both closer. Ryan clenched around him, begging. "Do it, Jake. Flood me. Make me your cumdump."
Jake's balls tightened. He buried himself to the hilt and unloaded. Thick ropes of cum blasted deep into Ryan's guts, pulse after heavy pulse. Ryan gasped as the heat flooded him, his belly starting to push outward. "Fuck, it's so much… keep cumming." Jake didn't stop. He kept thrusting through the orgasm, forcing more and more thick spunk inside. Ryan's stomach rounded visibly, skin stretching tight over the growing load. The inflation built fast, his midsection swelling like a balloon filling under pressure.
Jake pulled out only to flip Ryan onto his back, pushing his legs up. Cum leaked from the gaping hole, but Jake shoved back in and kept pumping. "Not done yet. Gonna double that load." He fucked harder, sweat flying, the wet squelch of cum and cock filling the room. Ryan's belly grew heavier, round and firm, pressing against his own chest as Jake leaned in. "Look at you, all bloated on brother cum." Ryan stroked his distended gut, moaning at the pressure inside. His cock erupted untouched, shooting across his swollen belly while Jake kept breeding him.
Another orgasm hit Jake. He roared, flooding Ryan again. The cum inflation intensified, Ryan's abdomen pushing out further, tight and shiny, sloshing with every thrust. Jake pressed his hand against the taut skin, feeling his own load shift under the pressure. "Fuck yeah, take every drop." Ryan panted, overwhelmed, his hole fluttering around Jake's still-hard cock. They stayed locked like that, Jake grinding slow and deep, milking out the last spurts until Ryan's belly looked six months pregnant, heavy and full.
Jake finally eased out, watching thick cum ooze from the wrecked hole. Ryan lay there panting, hands rubbing his inflated gut. "Best load yet, big brother." Jake grinned, already stroking himself hard again. "Round three. Gonna make you pop." He climbed back on top, pushing in slow this time, savoring the hot, cum-slick tightness. Ryan's swollen belly pressed between them as they rocked together, the sensation of the trapped load making every thrust filthier. Jake built up speed once more, chasing another massive orgasm to push the inflation even further.
By the time Jake finished the third round, Ryan's belly was drum-tight, rounded out obscenely, every inch of skin stretched and sensitive. Cum leaked steadily from his hole, but most of it stayed trapped deep, sloshing heavily inside him. They collapsed together, Jake's hand resting on the massive swell. Ryan smiled through the haze.
"Can't wait to do it again tomorrow." Jake kissed his neck, already planning how much bigger he could make his brother next time. The room smelled of sweat, sex, and fresh cum, the perfect ending to another forbidden session.
