There is a beautiful woman with a good posture and a dignified presence. Kasumi Morikawa, 26, is a married woman hoping to appear in an adult video. She has been learning piano since she was a child and has over 10 years of experience, so why did she end up appearing in an adult video? Her husband, whom she married at a young age, has a cuckold fetish and has a vulgar sexual fetish of making Kasumi play the piano without a bra or panties, or completely naked, and filming the videos to upload to the internet. She has been filming obscene videos to satisfy her husband's sexual desires, but she has also awakened to the joy of being watched, and as the couple's desires escalate, she has applied to do as she is told. This is the first time that her embarrassing and vulgar sex life has been made public, despite her having lived in a world far removed from the adult video genre.
