Hidden camera footage shot at a high-end massage parlor in Aoyama. The first woman is a local clothing store clerk. Responding to the therapist's suggestion, she inserts fingers into her vagina to feel internal pressure. Stimulated by a vibrating device, she involuntarily urinates. The second is a uniformed schoolgirl nearing graduation. With oil applied inside her genitals, she writhes in pleasure, screaming "It's bad!" as she experiences consecutive orgasms. Under stimulation from a sonic machine, she shrieks in a legs-up position as she climaxes. The third is a stunning 32-year-old with a perfect figure and big tits. She moans in pleasure during breast care, but writhes and cums during genital treatment. Overcome by the machine's sensations, she lifts her hips and twists her body in ecstasy.
