The feminizing water pump causes any human to become feminized, whether or not they were a girl or a guy who happened upon it. The water pump has a hose that will actively seek out people to feminize who are near it, but it can be controlled for the purpose of feminizing. a specific part of the body can be chosen to feminize depending in what orifice it is inserted to. for example, if it was inserted into the throat, it would feminize the head, but sticking it in someones butt would feminize their butt and legs, in a dick, would create a vagina, in nipples would affect breasts, and if put into a vagina long enough, would cause pregnancy. Sticking it in someones belly button would cause core body structure to feminize.
