A sinister organization plots to overthrow the nation and begins developing biological weapons. Female detective Rina infiltrates the criminal group lurking in the shadows, but a single misstep leads to her capture and use as a human experiment subject. With aphrodisiacs injected into her anus, her mind and body are overwhelmed by intense pleasure. As her pussy and anus are touched and a thick cock is forced into her mouth, Rina gradually loses her sanity, driven toward ultimate ecstasy. This path to climax is more than just a crime scene—it challenges the limits of human desire and rationality.
