Frank laid there, gasping, covered in his own semen as he basked in his first orgasm. He was honestly impressed by the distance he got, as well as how much his body had changed.
He looked over his small muscles and new body hair, as he flexed various parts to get an idea of how much it changed, admiring the new musculature he had suddenly developed, when as he was feeling, it suddenly seemed to get bigger!
All over him, his muscles pulsed slightly bigger, as he felt himself grow about 3 inches in height. Apparently the virus was still in him, making him grow larger! He looked like fit, although not athletic. He must have been 15 by now.
Frank continued to flex as one hand drifted down, eager to please himself again, but as he reveled in his new penis' size, he was surprised as his hand suddenly was pushed open!
Mounds of flesh grew from his hardened penis, as 6 inches became 9, then a amazing 13 inches! He could barely close his hand around it, amazed at the size of his manhood. He wanted to go through that feeling again! He moaned as he began stroking up and down again, gradually moving faster and faster as he basked in his pleasure. Finally, as his hand was little more than a blur, he began feeling a tightness in his lower stomach as his muscles began involuntarily tensing.
He shouted as he climaxed, his cum shooting twice as fast out of his giant cannon this time, firing numerous times with no let up. Breathing heavily, he gently stroked his softening cock a few times before standing up, letting it hang three-quarters of the way to his knees. Just what exactly was he going to do for clothes now?
