18-year old futanari schoolgirl Tomoe Akizuki, enthusiastic exhibitionist, goes on her first solo exhibitionist adventure, seeking to masturbate around the school grounds.
Just as she begins, she is caught by a male classmate, who has an interest in her.
The player chooses what happens next, with the scene either turning out to be a confession of love from the classmate and expression of that, or with the classmate exposing Tomoe's submissive nature, seeking to make her his willing sexual plaything and forge a D/s relationship.
The player also has control of how the ensuing sexual encounter plays out, choosing the foreplay, fun with sex toys and fucking scenes.
The choice of scenes gives the player one of four different endings.
