Hinano, a female investigator who doesn't want to forget human emotions, decides to retire from the organization. But her boss won't allow it, and she's suddenly put to sleep with a nerve-numbing drug. When she wakes, her body is being played with; despite her unwillingness, her sensitivity is heightened. Her vulva is exposed through a black rubber sheath, and she erupts in a volcanic eruption. Her vulva is compressed by a series of spikes, creating a piston-like motion, resulting in a humiliating orgasm. A massive dose of aphrodisiac causes her brain to leak out. Completely devoid of her former pride, she's reduced to a lowly sexual slave. "You think you can just quit? What an idiot."
