The Chinese-origin Contract of Subjugation finally reaches its conclusion! Aoi Yumi, a pure and innocent weather girl talent affiliated with the talent agency "Saint Star," falls victim to the lewd schemes of her perverted boss, Kohmi Shimohira. One day, Yumi begins visiting an esthetic salon, and her experiences there become the turning point that drastically changes her life. Under the guidance of the female manager Kaori, her untouched body is gradually awakened and manipulated in various ways. Her nipples are sucked by a breast pump, foreign objects are inserted into her anus—scene after scene of intense stimulation unfolds relentlessly. Her story intertwines with that of Midorikawa Saki, resulting in a masterpiece featuring ten erotic segments including anal sex, lesbian encounters, and orgies.
