Minori is a high school girl who was raped in silence because she was afraid of calling for help and being labeled as violent, so she suppressed her voice so that others wouldn't find out. Even if you hold back her voice, her sensitive body is honest, and her continuous orgasmic voice leaks out as a violent sigh, and the suppressed pleasure explodes at once! ! Surrounded by despicable men in a liminal space with no escape (toilet, infirmary, club room, classroom), convulsing.
