"Okay, fine, I'll put on some pants," said Sean, trying to get up, but unable to with Dan still straddling him.
Dan looked down at him thoughtfully. "Tell you what. You don't have to wear any pants as long as I can get some more of this—" Dan forcefully grabbed Sean's crotch "—whenever I catch you with them down."
Sean's eyes widened and locked onto Dan's still half-hard, dripping cock. It had gotten bigger when Jay buffed him up; Jay would have to shrink it or make his own larger to stay ahead of the game like he'd planned.
Sean's only thoughts were how it had felt inside him. He didn't say anything but quietly nodded in agreement.
"All right then, it's a deal," Dan said, standing and helping Sean up. "Go get yourself cleaned up," Dan ordered, slapping Sean on the butt.
Sean meekly disappeared into the bathroom.
Dan picked the remains of his clothes off his bulging physique. "Man, I'm outgrowing everything these days. Guess I'm just too studly to contain." Dan struck a pose that would have made a fitness model jealous and stalked out of the room.
Jay just sat there, an amazed grin on his face. This was the best prank ever.
And it just didn't stop. Jay had to bite his tongue to keep from howling in laughter every time he caught them going at it—and he caught them going at it everywhere. Sean made it a point to shed his pants the moment he got in the door, and Dan was equally conscientious about fucking him every time their paths crossed.
Life got a bit surreal for Jay, living with these friends he'd turned into sex-crazed musclestuds, one of whom wasn't a stud at all. And as hilarious as it all was, it was making him really horny...
