Both Chris and Dom had grown massive from the ass reaming that they had just given Jeff.
Chris had made it so that Jeff's ass would snap shut just as if it had never been pounded by either he or Dom or any other man. This would seal the copious amounts of cum inside Jeff ready to be metabolized. Jeff wouldn't have to eat again.
As Jeff bloated up with the gallons of cum he spread the two muscle men like a wedge between them. His soft form squished into the spaces left between the two muscle monsters.
Chris stood Jeff up and saw Jeff throw his shoulders back to balance the belly he now had. This made his stomach look even larger than ever.
Chris disappeared for awhile and then screamed for Jeff to come to him.
Jeff waddled into his room making slow work of it with his new girth.
There he saw Chris pounding on the Chronivac trying to make changes but his fingers were too big to make any changes on the machine and wanted Jeff to change him and Dom back to their normal size.
Jeff of course agreed. Sat down and double both Dom's and Chris' size in every area including their balls.
Jeff had thought about dropping the weight that he had been forced to absorb but he liked the bear look on him. He did give his smooth soft belly a furry pelt. He hadn't liked back fur so only gave himself belly and pec fir. But damn did he like being fucked since his brother and Dom had fucked him but he didn't want them to fuck him any more. He found himself in lust with large dicks mostly from black men but any big dick would do for him now.
So as he made the changes he made both Dom and Chris repulsed by Jeff but gave their cum the ability to make changes to any man they fucked. Letting them bloat just like Jeff had and have their asses tighten up when they pulled out to hold the massive amounts that their beach ball sized balls now produced.
Their now massive balls gave them a sex drive that drove them minute by minute.
They didn't care if the men were gay or straight they needed an ass to fuck as long as it wasn't Jeff. And asses they found.
