Chris remained stock still in his crouched position as he watched the next events unfold. Jason stood there, unmoving. His chest and face had a thick layer of cum which was flowing down his body. Jason had let his towel drop, and he stood there naked as the warm liquid reached his crotch.
Suddenly, Jason's dick sprang to attention and began to grow, the rest of his body soon following. He was growing taller, hairier and more muscular, just as Chris had. When he finally stopped, he was as tall as Chris, but because of his genetics, he had become hairier than Chris was, and he hadn't gotten as big, but his muscles were much more defined. Not to mention his cock and balls had also enjoyed a sizable increase. And, somehow, all the cum had disappeared.
Chris stood up and was now able to look Jason in the eye. But when he did, he noticed Jason was very pale and caught him as Jason began to collapse. Chris rested his friend's unconscious body against the bathroom wall and stared at him with concern. What should he do? And then, he had no question.
