Undercover agent Asahi infiltrates a human trafficking organization but is captured and sent to the "pig pen"—a facility known as Female Body Livestock PLANT, where women are broken down and transformed into livestock driven solely by cock hunger. Once a woman enters the pig pen, there's no return to the outside world. As her body is tormented and her mind gradually shattered, Asahi is swallowed by the desperate cries around her: "Cock... please, give me your cock, quickly, quickly!"
