Hibiki Otsuki, a star who can change, is finally appearing in the JOI series! [What is JOI?] It is a video that instructs and orders the viewer on the speed and frequency of masturbation, the time until ejaculation, and whether or not to allow ejaculation. - In the world where you are alone with a dirty talk, you are instructed to masturbate, and please follow the order and clear what you are told. - Please experience the overwhelming agony pleasure of being educated by metamorphosis with a impatient countdown that kills M man alive!
