Fitch's exclusive busty idol Reina Momozono has shown off her masochistic tendencies in her first circle work! At the school she started attending as a teacher trainee, Reina was considered a masturbation symbol for young male students and teachers. One day, a male teacher takes advantage of Reina's weakness and calls her to a hotel to threaten her. Reina, who cannot resist, listens to what her teacher says, but her demands gradually increase.
