"Please Vin, faster do it faster." Carlos is moaning and yearning for his domination.
"If I go any faster, you'll ending up melding into me." Vin pumps faster and pleasure flushes over. You never felt such ecstasy before the experiment that enabled you such desires.
"Then do it,do it, let me meld with you, let my body become part of you, there would be no greater pleasure than to give these muscles over to make Vin ever more a god!" Carlos pulls his arm around Vin's head to draw him in for a passionate kiss, his muscles aching to fuse with Diesel.
"I'll gladly except your offer. Now, become one with me!" Vin fucks Carlos faster, and his eyes roll to the back of his head.
Carlos loses consciousness and his body looks like a helpless rag doll, limbs flailing while penetration continues. Vin and Carlos' bodies become muck-like and their union commences. More and more Carlos mass combines with Vin.
"Mmm... the muscle this guy had, ahh... it feeds mine well, Ohh!" His from coming back, his biceps bulge even further, his backs fills up across as his muscles become bigger and more defined, his calves swell as well as his quads pushing his pelvis to open more."
"Carlos...you were unbelievable, I have become stronger because of you, but don't worry," Vin looks at his muscles," you are going to help me dominate more of your fellow bodybuilders to transform me into the god you want me to be."
Vin gets up and caresses his muscles into which he shape shifts into Carlos, with some bigger muscles and adapting some of Diesels charm and rough sexy voice.
Collecting Carlos' clothes you dress yourself and admire your new skin and the muscles that strain the limits of his clothes. Just for fun you look in the mirror and in Diesel's actual voice "I'm going to enjoy being a wolf in sheep's clothing." You leave the room and quickly your hunger for muscle swells again.
