The cold and arrogant elite agent Yuna Shiina goes undercover as a doctor to expose a sinister human experiment, only to become the prey herself. Forced to endure the raw, unrefined lust of the lowlifes she despises most, her high-class body is defiled and filled with their seed, leading to her ultimate, humiliating downfall.










This work fully satisfies the dangerous fantasy of 'restraining a capable, beautiful woman and tormenting her to your heart's content.' Watching the strong-willed Yuna get ravished by men and repeatedly reach climax is simply magnificent. The contrast between her glossy black suit and pale skin is beautiful, and her moans are music to the ears. I was thoroughly satisfied.
I usually don't like this series, so I hadn't watched it, but since I like this actress, I gave it a try and the content was incredibly erotic and great.
I decided to buy this because it features my favorite, Yuna Shiina, and it's a female investigator theme. Her sexiness was top-tier.
Yuna Shiina's performance while being violated is truly superb and exciting. I personally love this series, and this installment was great too!
Yuna Shiina's performance as the victim is simply outstanding. Watching a strong, intelligent, beautiful investigator struggle in vain against scumbag men before being violated is incredibly stimulating. The final scene with Mr. Sugiura is the highlight of this production. Seeing her restrained on the table while her beautiful body is toyed with was truly excellent. Her inner thoughts are interspersed throughout the act, which adds a great touch. 'It's touching...', 'What am I... thinking...', 'I'm... losing... myself...', the conflict between her reason and the waves of pleasure is well-portrayed, acting as a perfect spice to enhance the quality of the scenes. Without a doubt, this is the best in the series. It was a fantastic purchase that I don't regret at all.
