Your sister just got back from a party and really needs to POV. But you won't her get to the bathroom unless she gives you a JOI. You last too long, though and so she takes matters into her own hands... literally. Eventually, though she can't hold her pee any more and pees herself right on the bed and then is so turn on that she finishes the hand job!
