A Teacher x Student: I believe you know how this works. Teacher catches student alone or has blackmail, that kinda thing. Then Teach proceeds to mind break the student into a personal slut. Fem on Fem/futa/shemale A Heroine x Villainess: Heroine(possibly a new one) tries to foil a villaness' plot. vilaness proceeds to defeat and the though sexual acts corrupts heroine into a lacky or plain old sex slave. same as above. Yeah those are my two. hit me up if you wanna do either.
