There is a dark site where high school students take secret videos (bathing, masturbating, and even sexual activity) of familiar adults (teachers and parents) for the purpose of earning pocket money and buy them at a high price. The sneaky student reaches out to the visiting female tutor (active female college student). Aphrodisiacs and diuretics are mixed in the tea served to them, and sex toys appear at the right time when the medicine starts to flow, the sexual desire that was suppressed explodes, and the devil's hand extends to the pubic area. A female tutor who is taken a secret picture of the situation, shakes the video to the story, and finally is made to masturbate in front of the student with a mouth-stopping fee. The effect of the aphrodisiac that had been taken in advance was not cut off, and the body sensitively reached the climax, contrary to the psychology of resisting.
