Mark takes the laptop again and makes more changes. He adjusts Bobby's cock to 7 feet (still can't have him bigger) and adjusts his height too 7’5”. He then adjusts his weight to 800 lbs.
It was before Mark hit enter that Bobby questioned what he kept doing on the laptop. Mark realized Bobby had no idea about the Chronivac. Rather than explain he just made it so that Bobby knew that they had always had the chronivac and knew what it did. Seemed to be the easiest way to go about it.
Then Mark pressed enter. Bobby shot up a foot in height and his cock sprang from 15 inches to 7 feet almost instantly. His gut sagged and jutted out again in a huge ball of glorious flab. Then his balls sagged to the floor and spread out forcing his legs to separate.
Mark then made a change to himself like he did to Bobby earlier. He made it so that no matter his cock size Bobby cock could not harm him and that he would always be able to take his cock. He also made it so that his ass was always naturally lubricated as well.
Mark then laid on his massive gut and Bobby came in behind, his balls dragging behind him. Mark felt the cock enter his ass and it was a glorious feeling. Mark could feel the 7 foot cock moving through his bowels, through his stomach, and into his throat. Bobby then began to fuck him vigourously. They both cum after hours of Bobby fucking Mark. Covering everything in the room with Marks cum while Bobby's cum adds an additional 200 lbs to Mark.
