This work depicts the intense battle of undercover investigator Kotone, who single-handedly challenges a secret organization selling aphrodisiac oil, only to have her identity revealed and her limbs restrained, starting with a tense plot. Her extremely slender body glistens with oil, highlighting her beautiful skin and toned figure, as she endures extreme torment including double penetration, toy torture, massive squirting, and continuous creampie threesomes, which is breathtaking. Initially showing defiance with lines like 'Compared to training...', she gradually succumbs to pleasure, with a deep psychological portrayal of her pride crumbling, and the bridge orgasm scene is unmissable. Packed with highlights, details like erect nipples show meticulous care, and the transformation of an excellent investigator into 'just a woman' is captivating. Throughout, the blend of eros and tension is exquisite, making it highly watchable.
