Bryce flicked the switch to 14, set it to penis, and held his finger over the Start button for a brief second, before pressed it.
Matt's cock stiffened, erecting to its full 6 inches, then it grew. Stretching longer in the tube, it grew thicker. Blood vessels became more defined as it stretched past 10 inches hard. It passed a foot long and as thick as a beer can, finally settling at an engorged 14 inch bottle-thick cock. It stood rock hard against the tube.
Bryce lifted the InfiniPump off Matt's cock. It bobbed a bit in response.
Bryce then targeted Matt's balls. He wasn't sure what size to do. Half of him wanted to make him porportional, but half of him had a fetish for enormous balls. Well, what the heck, he thought, Matt's already getting an enormous cock, might as well go the whole way. Flicking the setting to 12, then testicles, Bryce placed the InfiniPump over Matt's balls (currently the size of grapes) and pressed start.
They began to swell up. First growing to the size of ping pong balls, they grew to baseball size before settling into softball size. When Bryce removed the InfiniPump, Matt's testicles looked heavy and huge, even compared to the 14 inch rod right next to them. Bryce was proud of his friend.
