Akari Shibukawa is 54 years old. A mother of one child who will celebrate her 30th wedding anniversary next year. She gave birth the year after her marriage and devoted herself to raising her child for the next 10 years. In these 30 years, the couple's activities have changed greatly, and now she feels like she is helping her husband with his sexual urges... Somehow wanting to bloom as a woman again, she started a part-time job outside, but she couldn't find a good encounter and was just frustrated... She's reached the limit of her patience. With the single thought of "I want to shine as a woman again," the chaste wife opens the sanctuary that she hadn't allowed anyone other than her husband to enter for over 30 years.
