Maybe im just weird but i love the idea of not being allowed to pee and then being forced to...one of my major turn ons is being made to drink loads of water and wait till i am desperate but being orderd not to go...hmmm.........
Hmmm, what you describe is similar to how I see a story of mine going... I've not decided yet if my female character will be 'punished' for peeing, or pleasured, or both! But she'll be holding it in, desperate to go, and when she does, it'll be because she cannot hold it in anymore...
