A high school girl challenges the Shake-Shake Pussy Game with the aim of winning a large amount of money! If you shake your body within the time limit and increase the pedometer count to the target number of times, you clear the game! The difficulty level increases with each of the three rounds, and the lewdness also increases! High school girls in uniforms move desperately, giving off a series of panty shots! They try wearing them directly on their bras and panties!? Their cute butts shake as their bras flash! Their panties get stuck in their pussy! If you fail, you'll have to play a lewd punishment game of intense pistoning until the pedometer count is cleared!
