Now that I know how to get all the achievements, I shall begin the journey of getting them all for the girls, since I cheated in a fuckton of money. If there is ANY reward at the end of it all, I will let you guys know.
EDIT: I am proud to say, that after pouring in more time than one should into this game, that once you get all the achievements... Nothing happens
Aside from the sense of accopmplishment you get from torturing a plethora of women with scat, piss, vomit, and many other things, of course.
