Peeing in her ass urine enema
Piss enema - LBON.CLUB
Description: I just find it more strenuous. However if it lites your fire go for it. So just be close to the bathroom I suppose. My EXGF used to like thee feeling of hot pee filling up her ass and would hold it for a good time with no side effects. I don't cramp as much as I do from tap water.
