Taku has a strong libido and has been asking for Reiko every night, but one day, when a man moves into the next room, Reiko is ashamed of leaking her voice and refuses. And when Reiko says, “I’ll do anything” to appease Taku, who is furious about it, Taku forces him to do obscene acts… Reiko hesitantly obeys Taku’s abnormal orders that escalate day by day. However, the act gradually gives Reiko pleasure.
