Junko Sakagami, 51 years old. She holds a remarkably positive attitude toward sex, so much that her family even watches adult videos together as part of their children's emotional education. Her open and proactive mindset reflects her serious approach to sexuality, and she believes regular gym workouts are essential to maintaining both her feminine beauty and libido. Meanwhile, her husband feels somewhat overwhelmed by her energetic nature. Recently preoccupied with work, he's neglected his fitness, resulting in declining bedroom performance. Amid this situation, he confesses, "I'm the one left with pent-up desire now. When I see the young male trainer at the gym, I get turned on uncontrollably," revealing how he's being driven to the edge by his wife's passionate energy.
