Mark is ready to blow again but he doesn't want to blow from a blow job. So he takes the chronivac and makes it so Bobby will be able to accommodate his massive cock and presses enter. He then also notices that he can also adjust the size of his balls via slider. There's a note that says that an increase in size will also increase volume of semen. Mark slid the slider and watched the display of what appears to be testicles get larger and larger. Mark then pressed apply change and his balls sagged immediately all the way to the floor.
His balls had become cartoonishly massive. Massive enough that they made his dick look small. Couldn’t have that. So Mark adjusted the size of his cock to 48 inches. A 4 foot dick soon towered over him and Bobby. Knocking the laptop to the ground hitting some keys on the way down. Mark was to aroused to care to notice that his sex drive had just been increased 10x what it was. It also adjusted his weight to 900 lbs, bumped the slider for his balls even further, added another 4 feet to his cock, and increased his height to 8 ft 11in.Mark reached to grab the laptop and accidentally pressed enter.
It was then that he shot up 2 feet taller. Then his dick and gut jutted out and his balls once again sagged to the floor but this time much wider than before. Mark was leaking pre from his now 8 foot monstrosity of a cock onto the top of Bobbys head who was trying to catch the cum in his mouth like a child trying to catch rain with their tongue. Mark grabbed the laptop off the ground and made another change. He made it so that Bobby's ass was always wet and ready and well lubricated.
Then Mark picked Bobby and shoved his 8 foot rod up his ass. His cock actually came out of the top of Bobbys mouth. But since he made it so Bobby would be able to take his cock no matter what it was nothing but pure pleasure for the both of them. You could see the head of Mark's cock go from the bottom of Bobby's huge gut all through his throat and out his mouth with each thrust. When Mark was close to climax, he pulled his cock back down to Bobby's gut. He then erupted the entirety of his massive balls into Bobby's gut. Bobby's gut got bigger. To the point where it rivaled Marks
Bobbys gut sloshed with cum. But Bobby's cock still remained hard at 15 inches.
