The first story-based story in the series, Mihina Hina, a pee-loving office lady, urinates from pleasure on her way to work, in the office, at a colleague's house... wherever she goes! Even though she has a sensitive body that is easily aroused, while she is holding in her pee, not only is Hina sensitivity doubled, but her masochistic side also doubles! Her boss's prank vibrator makes her pee, and when she makes him cum with a slutty handjob, she urinates all over him, and during raw creampie sex, she arches her back in ecstasy, squirts like a fountain, and is on the verge of fainting! Hina pussy has gone numb!
