There's a game where you can win a prize for walking around town with a beautiful girl, and they successfully got her to join a naughty game. The cute amateur girl, blushing, grips the penis for the prize money! The amount of sperm determines the prize amount, so they desperately try to get a lot out. They frantically search for the pleasurable spots within the time limit! From using her breasts, her sense of shame starts to get weird, and some girls even end up using their vaginas for insertion.
