Andrealphus,
I'm curious why there is not an option to end a bondage relationship? The cheat menu allows you to undo a pregnancy, and of course, you can break up with a girlfriend, you can even remove piercings. So I'm wondering how hard it would be on the backend for you to enable the termination of a BDSM status.
I understand the game design of wanting replay value, but there's not a lot of value in having to do the same route twice. It would be in excess of 44 save slots to do that, and that isn't even counting slave slots for harem combinations.
