Delayed reactions

Her (his?) dick suddenly got stiff sticking 9 inches straight out in front. And she starts to feel flushed and itchy. Looking in a mirror she notices a heavy 5 o'clock shadow starting high up on her cheeks, and quickly filling in and turning into a long bushy beard. Meanwhile the hair on her head starts to thin and fall out becoming bald, while thick hair sprouts on her chest and shoulders. Her breasts flatten slightly and become more masculine while a small firm beer belly grows out. Looking up her nose looks a lot stronger and wider. Her dick spurts out a massive load of semen just as a pair of huge balls seemingly flop down to her hairy theighs. Her orgasm is so intense, (s)he passes out right where (s)he was standing.
