This may sound crazy and like I've been reading too much Road Dahl but this is what I came up with when she asked what she could do to make up for the fact she cheated on me.

My Ideal Person The idea isn't for her to enjoy this so I'm not exactly looking for a special type, if anything the worse the better.
