Carissa has a particularly full bladder and the sensation often makes her horny. Today, she sits on a toilet naked, but instead of releasing she decides to hold it while she masturbates to make herself have an orgasm before she pees. She rubs her clitoris faster and faster, moaning as she brings herself up to a climax, then finally she allows herself to empty her bladder. Her expression shows both pleasure and relief as she squeezes the last drop of pee into the bowl.
