After several hours of intense fucking Jay passes out covering Sean with his massive body, his cock oozing pre- cum in his sleep. Sean lays awake, he slowly prying himself out from underneath the behemoth. Jay slides out carefully after several minutes of work. He sneaks down the hall nude.
He reaches the computer with the program on it, he pulls up his profile.
“Okay lets play Jay.”
Jay quickly changes his profile…
“Weight: 600 lbs of solid muscle…. I will top every man. “He quickly scans down the list. “Change this to 7’ 3”.. A solid foot above him.” He goes down to a box and changes a slider. “Hmmm… Pecs form, I can change them to be more breast like.” He slides the slider to the 3 / 4 mark. “Good” He says as he feels himself getting turned on by the thought that was about to happen.
Sean walks very sexually back to the bedroom. Jay remains asleep as his dick points erect at the ceiling. “I think I should wake him up.” Sean smiles as he climbs ontop of Jay. As he grinds his pussy up and down Jays dick, Jay wakes up and flips him on his back. “You just woke up my monster! Now get ready for him to enter your cave.” Jay thrust into Sean causing him to begin to moan.
Sean feels Jay becoming lighter and Lighter as be begins growing. It isn’t long before Jay feels the difference. He looks down at Sean, a look of shock on his face. Sean smiles and flips him onto the bottom. The changes begin to become more evident as Sean swells bigger with each thrust. His pecs have to be the size of trucker tires if not bigger. His arms have grown bigger than a normal mans waist. Jay thrust himself onto Sean’s cock as his butt begins to grow into a PERFECT muscle bubble butt, too big and thick for a normal man to fuck. The changes start to halt as his pecs droop a little taking on a full, thick shape with half dollar sized nipples.
“I hope you really are a fuck machine Jay, because you are going to be fucking for the rest of your life.”
