At Will

"... Well, anywhere."

"Actually, I need to explain a few things because this is odd. Your new reality will be such that peeing is entirely optional: you could never pee in your entire life; or you could pee every moment of your life, the choice is yours. It is worth noting that if you are your body will do whatever it was doing, but other than that it's entirely up to you. You can also pee pretty much anywhere you like, nobody will mind as it dries up without a trace soon enough anyway, and will not cause a problem. The only thing I'll warn you about is that going in the toilet can be seen as hogging it from people who need to poop but you can pretty much hold forever without problem so don't worry if you don't feel comfortable."

"But yeah, basically peeing is a matter of style and self presentation... or just a bit of fun, it's up to you."

"I'll stop talking now, I think you get the gist. Hope you have a nice day."
