Takigawa Hina goes to a locally famous all-girls school, and she's my girlfriend. We're both perverts, and our hearts are as one. ...at least that's what I think, but there's one thing she just won't show me. In front of my very eyes, for me and for me alone, I want her to pee!!! In order to take our relationship to the next level, I'm going to rise to the challenge...!!
