LHTD-007 — Challenge! Timer Electric Massager Riku Yuuna

What if you fixed a timer-programmed electric massager to a girl's vagina, gradually increasing the time with 1-2 minute intervals, and continued vibrating continuously? Five minutes... six minutes... ten minutes... As the vibration time gets longer, it becomes a dangerous threat. Two women are featured: Riku, a sensitive beauty with glasses, and Yuuna, who usually uses a vibrator to orgasm. The fixed camera is also a big hit, as it monitors the climaxing scenes of girls who come whether they want to or not!
