LHTD-001 — Challenge! Timer Electric Massager Miori Yurina Sakura

What if you fixed a timer-programmed electric massager to a girl's vagina, and gradually increased the time with 1-2 minute intervals to give her continuous vibrations? At first, the stimulation felt unsatisfying... but as the vibration time increased, it became a dangerous threat. Five minutes, six minutes... 10 minutes... The girl, who had begun to feel cornered, began to long for the intervals, but the timer that had been set continued to give her strong vibrations mercilessly!
