An erotic story depicting the desires of a middle-aged wife. A 45-year-old woman from Kanagawa, working as an esthetician, recounts her 18-year affair. Mother to a 16-year-old daughter and a 13-year-old son, she hasn't had sex with her husband, who is approaching fifty, for nearly ten years. Despite raising her children, her libido remains strong—she frequently masturbates and enjoys sexual encounters with male clients at work. One day, she meets a male door-to-door sales representative. Drawn to his kindness and rugged charm, she yearns to continue their relationship. Desperate to remain special to him, she keeps buying his products, piling up debt, yet her desire to stay with him grows stronger. Every day, she looks forward to being with him again.
