She looks plain, but once she takes off her clothes, you'll see a close-up of the pussy of the supermarket cashier, Ryoko! After opening and closing her hairy pussy, she inserts a thermometer into her pussy to measure the temperature inside her vagina. After that, she uses a medical tool to widen the opening of her pussy, allowing us to take a closer look inside, and then she uses a vibrator on herself and masturbates vigorously until she cums! It's so erotic to watch the naughty juices slowly come out!
