Maki Hojo is a beautiful, slender married woman with a seductive figure, living a wealthy life as the wife of a major corporation's CEO. However, her husband has lost all interest in sex at night, leaving her in constant sexual frustration. One day, her husband leaves town for an extended business trip, and Maki begins indulging in self-pleasure from morning onward. She seduces a male delivery man who arrives at her door, giving him passionate blowjobs and teasing him with adult toys. A few days later, another delivery man visits, and she draws him in as well, enjoying a wild 3P sex session. Her husband eventually discovers her affairs and punishes her harshly—but to Maki, the discipline only heightens her pleasure. In the end, aroused by her infidelity, her husband regains his long-lost sexual desire, leading to a satisfying and happy resolution.
