36-year-old taxi driver and married woman Nagisa Ayase. She's not good at being affectionate and is the type who constantly gives to others. She married a salaryman six years her senior at just 19, then remarried at age 32 to a 9-years-older comedian she met through work. Juggling child-rearing and her job, she realizes it's been nearly two years since she last had sex with her husband. She rarely expresses her sexual desires, relieving daily stress through masturbation four times a week. However, as she grows older, she's starting to feel anxious about her lack of sexual fulfillment. To satisfy her hidden desires, we closely follow her daily life and delve into the passionate depths of her inner self.
