Aya Hirahara is a voluptuous female college student who gets caught up in a sudden, unexpected incident. Captured by a man with abnormal desires, she is bound tightly with jute rope. Unable to move her body, she endures his torment as the deep-seated masochistic side within her slowly begins to awaken. Amidst feelings of disgust and resistance, her consciousness gradually shifts, guiding both her mind and body toward a new realm of sensation.
