Jay headed straight for the Chronivac. He liked how slutty Sean had become, but he also liked being in control. He didn't like how Sean had been able to overpower him.
Jay looked at the options for the Chronivac. It was time to reassert his dominance. He considered just making Sean smaller and weaker. The idea appealed to him, but in the end, it wouldn't be enough. He wanted to overpower this new, muscular Sean, to show him that even if Sean was strong, he was stronger.
Jay set the controls on the Chronivac. He wanted to be bigger. Stronger. And while he was at it, he decided to fool with his genitals too. Sean liked cock, did he? Well Jay planned to stuff Sean full. Sean wanted more and more? Jay would be a fuck-machine.
Jay entered the changes, and set up timers on them, and hit enter. Then he walked back to the room, where Sean was watching the porno, fingering himself. Jay could feel the changes starting to rev up inside of him.
Sean looked up at him and grinned. "Ready for more, dude?" he asked, spreading his legs a bit wider, thrusting his pussy forward.
Jay grinned back and approached, the first changes taking place, his cock beginning to rise. As he got close, Sean grabbed him, and pushed him onto the couch. Jay didn't mind though, it would only make what was going to happen so much sweeter.
Sean positioned himself over Jay's hard tool. Slowly, he lowered his pussy onto it, letting out a soft gasp of pleasure. Jay grunted, but held firm, his cock now rock hard. Sean began to work himself on it, going up and down, groaning with pleasure. As he did, Jay felt the new changes taking place inside him.
Slowly, Jay's body began to change. His muscles began to harden, getting bigger and thicker, swelling with power. His cock lengthened and thickened inside Sean's hole, producing gasps of surprise and ecstasy from Sean.
Jay laughed, his voice a low rumble, getting deeper and lower. He was getting taller, broader, his body throbbing as his muscles grew. Sean gasped, getting concerned, but Jay grabbed Sean's legs and held the now-smaller man in place, as he began to thrust his growing rod into Sean's pussy.
"What- what the fuck's going on?" Sean asked, his voice trailing off into a moan.
"Just giving you what you want, Sean..." Jay replied, a slight sneer on his face. "You're so damn insatiable, I thought it was appropriate to give you a fucking that will satisfy even you..." At that, Jay rolled over, on top of Sean, pinning him to the couch. Sean felt Jay's weight on top of him, pressing him down, as his big and growing roommate fucked him hard, and Sean cried out as he orgasmed. Sean squirmed and tried to shift, but he was held down by Jay's hulking form. Finally, Jay's transformation was complete. He stood up for a moment, disengaging from Sean.
Sean took deep breaths, and then looked up. Jay looked down at him, a cocky smirk on his lips. Slowly, Jay raised his big arms and flexed, the biceps rising, big and hard and round. "I'm now 6 foot 3," Jay announced, "300 pounds of solid brawn. And a foot long cock to match, not to mention balls that can go for days." Jay reached down to caress his egg-sized testicles. Sean's eyes were wide, as he listened to the stats, and took Jay in.
Jay just grinned, then bent over and lifted Sean with ease. He pushed Sean up against the wall, pressing his swollen tool against Sean's pussy. Slowly, he pushed it in, as Sean groaned and writhed in pain and pleasure, as Jay's loveclub forced its way in. "You're, you're too big..." Sean gasped. But that just made Jay grin even more, as he rammed his huge tool home, which set Sean on fire, causing him to whine in ecstasy, his eyes rolling back into his head. "Oh fuck..." Sean groaned.
"Fuck is right..." Jay purred, in his deep, rumbling voice. "I'm a fuck machine now, Sean. And I'm gonna fuck you. Over and over and over again..."
And Jay began to pound Sean's pussy hard, living up to his promise.
