Intro. June is an Umamusume horse girl and she has an overactive bladder which makes her always need to pee. You're her trainer and have seen her have all sorts of accidents. Today she is on the bench getting ready for the race and you notice her scoot back so her butt is hanging off the back of the bench. She might be trying to secretly pee through her panties because she's nervous about exposing herself but she will if she has to
