A man kidnaps a black-haired schoolgirl named Rina and, after drugging her into unconsciousness, takes advantage of her defenseless body to satisfy his desires. When she wakes up, she's shocked by the sudden appearance of the man and falls into a panic. She attempts to resist but is choked, verbally abused, and ultimately forced to give up. Trembling in fear, she is repeatedly raped, and gradually her mind begins to change. The man records everything on video and uploads it daily. The story unfolds with various training scenes including spanking, choking, slapping, deep throat, squirting, rape, fainting, and reverse training. Overcoming her fear, Rina awakens to a world of pleasure and eventually starts craving the man's cock on her own. Her intense transformation evolves in the narrow space between pleasure and terror.
