Narcotics Division chief Ayanaka Seto has long taken pride in her unwavering beliefs and professional integrity. However, one day she falls victim to a cunning trap set by a drug trafficking syndicate and is helplessly captured. She is then injected with a vile aphrodisiac—the very substance she despises—triggering a horrifying transformation. The drug specifically targets the most intimate parts of her body, her anus and labia, heightening her sensitivity beyond control. Overwhelmed by humiliation and shame, her senses amplify rapidly, plunging her into relentless, overwhelming orgasms. One after another, these intense climaxes erode her will, turning her into a slave of pleasure. Under the torment of this sadistic criminal, Ayanaka descends into a depraved prison of lust and suffering.
