Shiori, 18, has a hobby of street dancing. She comes from a family that is open about sex, and she usually watches adult videos with her father. She decided to appear in the film, saying, "I want to become an adult woman like an actress!" Although she is still a beginner with only two sexual partners, her physical abilities and motivation cultivated through dancing pass the mark! As soon as the filming started, an accident suddenly occurred. As soon as she was penetrated, bright red blood came out of her vagina. Thinking that it was "girl's day," she asked, "Actually, it's my first time. I'm sorry for lying." She revealed that she was still a virgin. The pain was greater than she had imagined, and it seemed inevitable that the filming would be stopped, but at her request to continue filming, we continued filming... This is a genuine documentary of a virgin's loss, with no setup or staging. A rite of passage for a girl to become an adult... Please witness that moment.
