Akane Niimura is bored with her high school experience. In search of some extra stimulation, she decides to join the Futa Club as a “service member.” The club is made up of futanari - hermaphrodites - who spend their club time thoroughly enjoying each other. Despite wanting to be a part of the Futa Club, Akane is actually an ordinary girl. Thanks to that, her “service” duties are restricted to letting the other members of the club have their way with her. Akane is more than willing, but will she be able to pass the entrance exam?
