A sex video owned by an adult production company has leaked, sparking widespread attention. This company conducts interviews with women seeking to appear in adult videos while they are completely naked. From these sessions, only those deemed suitable for actual intercourse (penetration) are selected for production. The woman featured this time is a 20-year-old attending university in Tokyo, with only her ex-boyfriend as her prior sexual experience. She appears shy and reserved at first glance, but masturbates about four times a week. She also has a deeply masochistic side, becoming aroused when her neck is choked. This extremely unique filming situation produces rare footage that is otherwise impossible to see under normal circumstances.
