Mark rubs his hand across his stomach as he thinks. The feeling of his stomach thickening, the blond hairs growing under his fingers is too much, he likes it, there is no way he is going to stop it.
Mark climbs on top of Simon's thick hairy thighs, rubbing the outline of his cock in the now tight boxers, running his hand up Simon's thick and hairy stomach, squeezing his strong pec as it gets hairy.
Mark lays forward onto Simon, pushing his nose against Simon's upturned one, pushing his tongue inside Simon's mouth, running it across his growing tusks as they kiss. Mark's ass is in the air as he kisses, his cheeks thickening with muscle and fat, the strap of his jock moving deeper into his crack as blond hairs flourish across the glutes.
All around the room the other men are rubbing their stomachs, doubling and tripling up as they start to grunt and explore each other, heads turning to mush as their brains below their belts take over.
