Amateur girl challenges to turn off the electric massager exactly at 100 seconds while both feet are restrained and fixed, aiming for a high prize! Suddenly, her panties are fully visible, leading to inevitable embarrassment! But she wants the money! However, the vibrations from the electric massager are too stimulating, making it impossible to concentrate and resulting in repeated failures! With a 300-second setting, she tries again, but lewd pranks make it even harder to focus! Her clothes are pulled aside, her breasts are touched, and she feels it all over! As expected, the second attempt also fails, leading to an immediate penalty game of a full five-person fuck for all participants!
