USAG-096 For secretly perverted amateur girls only!! If you can keep your panties dry while being shown a man's fully erect cock for 10 minutes, you win a prize! However, if even a small stain appears, you'll be punished with a cum-in-her-pussy sex game!!

A masturbation viewing game where girls are forced to watch a man's fully erect penis up close for 10 minutes. The amateur girls confidently declare, "I won't get wet!", but when exposed to the pulsating heat and stringy, obscene flesh, their panties are stained with fluid by the end of the game. And the moment they get even slightly wet, a merciless cum-in-the-vagina sex punishment game is triggered!
