Jake slammed the door behind him, his cock already half-hard from the texts his little brother had been sending all day. At twenty-four, Ryan was still the same needy slut who'd started climbing into Jake's bed years ago, but now he was carrying Jake's kid and it made everything filthier.
"Get in here," Jake growled, finding Ryan sprawled on the couch in nothing but an old T-shirt that barely covered his swollen belly. Six months along and Ryan's gut was round and tight, the skin stretched shiny. His dick hung heavy between his spread thighs, already leaking.
Ryan grinned, dirty and eager. "Took you long enough. Been fingering myself thinking about your load."
Jake didn't waste time with talk. He yanked his pants down, thick cock slapping out, and shoved Ryan's legs wider. The belly got in the way but that only made it hotter. Jake rubbed the head of his dick against Ryan's slick hole, already wet and open from earlier play.
"Fuck, you're dripping," Jake muttered, pushing in slow at first then slamming home. Ryan's ass clenched around him, hot and greedy. The mpreg had made Ryan's body even more sensitive, his prostate swollen and easy to hit. Every thrust made the pregnant belly jiggle, and Jake grabbed it with both hands, feeling the life inside while he pounded his brother's hole.
Ryan moaned loud and filthy, "Yeah, breed me again, big bro. Knock this pussy up while it's already full." He reached down to stroke his own cock, precum stringing from the tip. Jake fucked harder, balls slapping against Ryan's ass, the wet sounds filling the room.
He pulled out just long enough to flip Ryan onto his hands and knees, belly hanging low and heavy. Jake drove back in, gripping Ryan's hips and watching his cock disappear into that tight, incestuous hole. "Gonna fill you till it leaks out your pregnant cunt," Jake snarled, pounding deep. Ryan pushed back, begging for more, his belly swaying with every thrust.
Jake reached around to rub the stretched skin of Ryan's belly while he fucked him, feeling the kid move inside as he railed his brother. It pushed him over the edge fast. He buried himself balls-deep and unloaded, thick ropes of cum pumping straight into Ryan's guts. Ryan came right after, shooting across the couch cushions with a broken moan, his hole milking every drop from Jake's cock.
They stayed locked together, Jake's softening dick still twitching inside. Ryan panted, "Don't pull out yet. Feels too good with your load in me."
Jake smirked and started moving again, slower this time but just as dirty, already planning the next round. The family secret was safe, and the breeding wasn't over.
