Don’t you love a bit of transformation? Like a human woman being turned into a sex crazed non human bimbo? Rejecting humanity to be better suited to sex is a truly amazing thing! Don’t you agree?
All joking aside, transformation is a decent kink, that's one of the reasons one of my OCs is a slime girl that can shift her body at will (and she enjoys men AND women, so lots of potential for shenanigans).
