A married woman with two daughters, aged 6 and 2, Ayaka Mutou. She has been in a sexless relationship for two years. Based on her friend's experiences, she believes that sex enhances a woman's charm. In front of the camera, she gradually undresses and exposes herself masturbating. If an erect penis is jerked off in front of her, she might have sex with someone other than her husband for the first time in two years. Eventually, she even accepts her first threesome.
