Madonna Ryouko, a popular figure in the shopping district, captivates everyone with her warm and sensual charm. One day, after being asked to participate in the neighborhood rivalry sports festival, she begins training. Following practice, she joins the committee chairman, Tabyuchi, and mechanic Tatsu for a celebratory drink. Drawn into a conversation about Tatsu's virginity, Ryouko surprisingly shows interest and, with Tabyuchi's encouragement, begins to unleash her own allure. Watching her secretly, Tabyuchi grows increasingly aroused, and as the days of practice continue, their relationship deepens. Ryouko is the perfect blend of warmth and sensuality, her appeal shining even brighter through the sports festival preparations.
