There is a black site where high school students secretly take sexual videos (bathing, masturbation, and even sexual acts) of adults (teachers and parents) close to them for the purpose of earning pocket money and buy them at a high price. The despicable student extends his evil hand to the visiting female tutor (active female college student). The tea served to them was mixed with aphrodisiacs and diuretics, and when the medicine began to circulate, an adult toy appeared at the right time, the suppressed libido exploded, and the devil's hand stretched to the pubic area. - A female tutor who is secretly filmed of the situation, extorted by the video, and at the end, is made to masturbate humiliating in front of the students with a gag fee. The effect of the aphrodisiac that was drunk in advance did not wear off, and contrary to the psychology of resisting, the body sensitively reached the climax.
