Asami Nemoto. A mother of one child celebrating her 22nd wedding anniversary. She looks like she's in her 30s with her firm skin and a bodyline with a perfect waist, but she's actually 50 years old. "The secret to youth... is sex (laughs)." The hormones secreted during marital relations are the best anti-aging treatment. But in recent years, as her husband's physical strength has declined, their relations have become quite bland. When she starts to feel a lack of pleasure and hormones, the word "cheating" begins to flicker in Asami's mind. "I'm like a woman who can't live without sex." Please see the challenge of a 50-year-old wife who has realized that she is a perverted woman.
