Votes are in and it seems pussy punishment, enema and suspension bondage have come out on top.
So I started work on a Shibari scene. I'm not sure if I can call this suspension - she's slightly raised off the floor but not completely suspended - but I think it's a nice pose and allows access to her holes.
I also noticed that a few people are not too keen on the enema option. Therefore I will make this entirely optional. As someone mentioned in the poll comments I could do a something like have the player insert a suppository that makes her breasts bigger, so you can have the option to do that instead.
Thanks for the comments by the way. Even if I don't have time to reply, I do read them all and they very much influence the game.
