Moaning, "I came... I came!!" while her body convulses and she orgasms repeatedly, the married woman Sumi finds herself trapped in an endless spiral of pleasure. Coming from a wealthy household, she made a grave mistake in a moment of weakness. Now, blackmailed by a rapist who holds her secret, she is forced into submission. Due to his delayed ejaculation, he keeps changing positions and pace, but each time, Sumi reaches climax first. Growing increasingly frustrated, the rapist continues assaulting her, his lack of control only heightening her pleasure, driving her to orgasm after orgasm. Her state appears as though she has completely lost all self-control.
