Perverted college girl Miyuki was driven to the edge by jealousy and verbal abuse from those around her, becoming hypersensitive to the point where her body burned with arousal. One day, she was secretly filmed masturbating on a classroom desk, and soon found herself subjected to blackmail and bullying. Though initially terrified, she began to feel pleasure from the fear and coercion, surrendering herself to the control of a delinquent student circle. She was forced into deep throat, stimulated with vibrators, gang-raped... gradually losing herself completely as she drowned in pleasure. As she came to accept this abuse as part of her daily life, Miyuki fell entirely into depravity.
