I actually watched the latest work by director Inugami Ryo, and it's truly a shocking masterpiece! Yuki Shiro Mio, who was just one of many subordinates and seemed plain and unnoticeable, unexpectedly transforms in a way I never imagined. Her fair, glossy, and voluptuous body, hidden under modest clothing, explodes with a gap in bust size the moment she undresses, captivating viewers instantly. Her looks and body are impeccable, and she skillfully uses a variety of sexual techniques to perfectly embody the character of a "sexually obsessed, mentally unstable, perverted plain office lady."

The film is filled with electrifying perverted preferences, and her appearance with an ecstatic expression while passionately devouring the penis leaves one breathless. This addictive charm is unforgettable once seen. However, the plot of sexual training leading to pet-like submission felt somewhat thin. If it had emphasized her transformation and seductive femme fatale vibe more, it could have been an even hotter production. Especially in the cowgirl position, when the man is about to climax, instead of holding his waist to stop the movement and avoid it, a bolder direction that lets him cum directly would have added more dramatic intensity.

Nonetheless, Yuki Shiro Mio's acting skills and body curves shine in this work, making it worth watching not just for AV fans but for anyone. The director's talent is evident, realistically portraying the metamorphosis from a plain OL to a perverted beauty, offering plenty of entertainment value. This is undoubtedly a hidden gem that raises high expectations for her future performances.
