MMGH-179 - Yuka, a sister-like girl who desperately tries to hold back her voice, experiences restraint toys for the first time

Pick up female students under the title "1 million yen game in just 3 minutes"! We had them participate in a game where they had to measure their time for 3 minutes while their bodies were restrained and an electric massager was applied to them or a vibrator was inserted. It seems that the first restraint toy experience was a little too stimulating... She had convulsive sex while shaking her hips and shaking her legs!
