This is pretty gross. I don't think you can get away with saying "... I doubt much rape would be going on..." because in this setting it's going to be a part of the backstory of pretty much *all the characters.* I feel uncomfortable just knowing that you want to do this. It really is quite obvious that you have a personal stake of some kind in the sexual slavery of at least some of the player characters, whom you also want to be catgirls and bunnygirls apparently - and I don't know whether that's because you want to feel like you're saving them, or because you like the idea of the suffering behind it, but it's really creepy.

RPG is not the place for this RP. If you want something like this, do it privately.
