After actually watching this work, I was impressed by the outstanding acting skills of Sawamura Reiko and Mori Nanako, making it a masterpiece. The story begins with Yuki (Sawamura), who married after an office romance, being stopped by her former junior Saki (Mori). While Yuki is happy about the reunion, Saki's heart is filled with hatred, and this contrast adds depth to the narrative. Sawamura Reiko has many scenes where she endures piston-like movements, and her desperate demeanor is portrayed realistically, especially the scene where she is bound, tormented, and climaxes wildly is overwhelming. The sensual sex with a red mask and the tension when the mask is removed are also not to be missed. Mori Nanako's revenge character has a shrewish feel, and her performance of controlling men to corner Yuki is excellent, with a striking gap from her beautiful appearance. The play involving attacks with a strap-on and the scene where she torments the husband with verbal abuse and handjob to make him climax are stimulating. Both actresses, with over a decade of experience, fully demonstrate their skills, and the realism of their acting is unparalleled. The plot where Yuki is kidnapped due to hatred and violated in front of her husband is tense, and her crying 'It's a lie, don't believe it' while dripping with lustful fluids draws the viewer in. However, some parts of the development feel a bit fast, and a bit more middle-ground depiction would have added more depth. While some voices prefer younger actresses, the experienced performances of these two are the core of this work. The rape scenes look so real that it seems like actual violation, and Sawamura Reiko's climaxing is intense, exciting even after multiple viewings. Throughout the film, the excitement of women tormenting women's expressions and the eroticism of shaking H-cup large breasts are packed, and the direction is also superior. It's a pity that there were fewer lesbian scenes than expected, but overall, it's a highly satisfying piece.
