I was thinking that this could take place in a heavily stratified society with a caste system of some kind. I'm a member of the lowest class in this system, and you're a member of the highly privileged upper class. I'm your slave, and you continuously humiliate me, beat me, etc. for years. However, one drunken night you forget to lock me in the cage that you keep me in, and I decide to break out and take my revenge. I threaten you with a weapon, and humiliate you, rape you, torture you the same way you've done to me for years. I realize this is dark, but it could be interesting. As for characters, anthros are adored, but I also enjoy hentai/anime style characters, and females and femboys with big, fat asses will take priority over others. If interested, please send me a pm to let me know.
