In a certain location in Tokyo, the "Pussy Torture" group has captured a new target. This time, it's schoolgirl Riku Shiina. Pure and innocent, she is restrained and stripped of freedom, gradually lured into a hell of pleasure. The torture begins with brushes and straws, escalating with aphrodisiacs and countless vibrators. Suspended from the ceiling, she's driven into an ultimate vibrator hell. Her face and vagina twist in ecstasy as she's pushed to the peak of orgasm. Each step of torment tightens its grip on her body and mind.
