Jack then wished for a virus to infect people. the virus will be random in the way its spreads. it will turn men and women into mythical monsters, always male. of course, to keep humanity alive he put in some safeguards. no matter the gender a pussy will form under their balls and will be completely hidden by their fur or balls. only to be found when the beast bends over to mate.
they will succumb to their instincts but keep their intelligence. they will become more sexually active. they will always be able to speak. there will be two types of myths. one will be the typical version of the creature. the other one will be an anthro one for example a Pegasus on two legs. each anthro will be muscular beyond belief. of course, the typical versions will include animals, a woman could turn into a bull.
with these safeguards in mind Jack finished his wish. the only question is who will be the first victim?
