A high school girl who moved alone from the Kansai region is captured by her neighbor in the same apartment building. Pretending to coincidentally meet her in the elevator, Rima presses a suspicious cloth against her face, knocking her out and carrying her into his room. There, he rapes her and performs creampie after creampie, then forces her to masturbate. He corners her with lewd photos, turns her into a sex slave, trains her using toys until she convulses and climaxes violently. He deep-throats her until he cums at the back of her throat. Her reason shattered, the girl goes mad, frantically mounting him and thrusting her hips to reach consecutive orgasms. What will become of her in the end...?
