Jake slammed the door behind him, his cock already hard in his jeans as he spotted his younger brother Ryan sprawled on the couch in nothing but tight briefs. At 28 and 25 they knew exactly what they were doing, and tonight the heat between them burned hotter than ever. "Strip," Jake growled, voice low and rough. Ryan grinned and peeled off the briefs, his own thick dick springing free, already leaking.
They didn't waste time with talk. Jake shoved Ryan onto his hands and knees on the living room rug, spitting on his hole and working two fingers in deep. "Fuck, you're tight," he muttered, pumping them hard while his free hand stroked his own heavy cock. Ryan pushed back, moaning dirty encouragements. "Give it to me, big bro. Stretch that hole." Jake replaced his fingers with his cock in one thrust, burying himself to the balls. He fucked Ryan fast and mean, skin slapping, sweat dripping, the room filling with the wet sounds of raw pounding.
After the first load Jake stayed inside, grinding deep. His balls drew up again and he unloaded a second time, flooding Ryan's guts. Ryan gasped as the heat spread, his belly already feeling fuller. "More," he begged. Jake pulled out only to flip him onto his back, legs hooked over his shoulders. He slammed back in and kept going, third orgasm hitting harder, cum pumping in thick ropes that had nowhere to go but deeper. Ryan's stomach began to push outward, skin stretching tight and shiny.
Jake kept thrusting through it, feeding his brother load after load. Each climax made Ryan's belly swell further, rounding out like he was carrying a heavy meal. Cum leaked around Jake's shaft but most stayed trapped, inflating Ryan inch by inch. Ryan rubbed his own distended gut, fingers pressing into the firm swell. "Look at me," he panted. "You're pumping me so full, bro. My belly's getting huge." Jake grunted and came again, watching the skin stretch more, Ryan's navel popping out.
They moved to the bedroom. Jake laid Ryan on his side and spooned behind him, cock never leaving that cum-slick hole. He fucked slow and deep now, letting each new orgasm build pressure. Ryan's belly grew rounder, heavy, resting against the mattress. Every spurt added to the inflation, making him moan louder as the pressure mounted inside. "Can't stop cumming," Jake snarled, hand gripping Ryan's swollen middle.
"Gonna keep filling you till you can't take any more."
Ryan came untouched, his cock spurting across the sheets while his gut sloshed. Jake didn't let up. He rolled Ryan onto his back again, straddling and riding the swollen belly slightly as he fucked downward. The extra weight made every thrust hit deeper. Load after load pumped in, Ryan's abdomen now noticeably distended, tight as a drum, shiny with sweat. He looked pregnant, belly jutting up, sloshing with every movement. Jake pressed both hands on it, feeling his own cum shift inside his brother. "Fuck yeah, take it all," he said, voice raw.
They kept going for hours. Jake's stamina seemed endless, each orgasm feeding the next. Ryan's belly grew larger still, skin stretched thin, veins visible, the weight making him breathless and blissed out. He cradled it with both hands, rocking gently as Jake pumped yet another thick flood into him. Cum finally started forcing its way out in messy spurts around the base of Jake's cock, but most remained trapped, keeping Ryan massively inflated.
When Jake finally pulled out, a thick river of cum followed, but Ryan's belly stayed huge and round, heavy and warm. He lay there panting, stroking the massive swell. Jake knelt beside him, running his hands over the inflated gut, squeezing gently so it gurgled. "Look at you," he said, voice hoarse. "My little brother, all bloated with my cum." Ryan smiled, satisfied and sore in the best way. They stayed like that until the pressure eased naturally, the night ending with slow kisses and the shared knowledge they'd do it again soon.
