Kanhata Ichika is a lone special agent whose existence is known only to the highest echelons of the special investigation unit. Standing at 172cm tall, Ichika fights on equal terms with the men of criminal organizations, but is captured when Murakami Ryoko, who taught her the basics of being an investigator, is taken hostage. Ichika is subjected to a vulgar physical examination that ignores her human rights and is given sexual substances, leaving her in a daze, where she is thoroughly trained to experience the pleasure of restraint. Even so, Ichika refuses to talk, so she is subjected to high-voltage electric current torture and extremely thick penis sex! She screams and cums over and over again, and then a humiliating raw creampie fuck ensues inside her vagina!
