LHTD-002 — Challenge! Timer Electric Massager Yui, Koyuki, Hiro

What if you fixed a timer program vibrator to a girl's vagina, and gradually increased the time with 1-2 minute intervals to give her continuous vibrations!? 5 minutes, 6 minutes... 10 minutes... As the vibration time gets longer, it becomes a dangerous threat. Yui-chan with her G-cup breasts, Koyuki-chan, a seductive beauty with an extremely erotic pelvic dance, and Hiro-chan, a pure girl with outstanding clarity, experience their first ever SM-tic!
