The story begins with Akihiko, who quit his job at a major insurance company to work at his father's factory, becoming attracted to his stepmother, Maiko. After secretly filming her talking to a stranger on the street with his smartphone and threatening her, only to be firmly rejected, he holds a grudge and uses aphrodisiacs to gradually train her into a sex slave—a plot development that is truly shocking.

Particularly noteworthy is the performance of Maiko Kashiwagi. She fully embodies the role with her sagging breasts, lack of waistline, and loose, large buttocks—typical of an older woman's physique—and her repeated climaxes with eyes rolled back are breathtaking. While some critics call it overacting, I believe this realistic portrayal actually heightens the excitement and doubles the work's appeal.

Despite being in the aphrodisiac genre, the actress's acting skills shine through in Maiko's transformative journey, making this arguably her best work to date. The constant ecstatic expressions draw viewers in irresistibly, and many fans are eagerly hoping for a sequel featuring her return. I myself became hooked on this piece, watching it repeatedly.

Overall, it's a masterpiece that skillfully depicts the psychological descent from everyday life and the physical changes involved. As a standout in Maiko Kashiwagi's career, it will undoubtedly be remembered and discussed for years to come.
