40-year-old Yoshiko Shiraishi. Married for 15 years, a housewife with a 10-year-old son. Since giving birth, she feels her husband no longer sees her as a woman. While she doesn't particularly desire sex with her husband, she dreams of a relationship with a younger man who can skillfully and gently lead her. To fulfill this fantasy, a young man was arranged as she wished, and she turned out to be surprisingly pent-up with sexual frustration. Despite her refined, gentle, and ladylike appearance, she revealed an utterly inexperienced nature and, deep down, a surprisingly erotic personality.
