Maho decides to start working at a soapland, replacing her husband who is unreliable both financially and sexually. It's a win-win situation—she can satisfy her own desires while earning income. Determined to become a top attraction with her stunning body, she sets her sights on becoming the number one soapland girl. However, having long relied solely on her relationship with her husband, her body has grown unaccustomed to erotic experiences after years of sexual inactivity. On top of that, her lack of experience in the sex industry presents an additional challenge, making her path far from easy. To achieve her goal of becoming the top soapland worker, she turns to her son as her practice partner, desperately honing her skills through relentless training.
