This time, our target is college students with high academic backgrounds! A senior guy and a junior girl are challenged to a Rock-Paper-Scissors game! Since she says she doesn't see him as a romantic interest and they're just friends, he'll get a cash prize if he doesn't get aroused! ...But as expected, just seeing the cute junior's underwear makes him lean forward, and if he sees her naked, he gets a full erection! The penalty game is raw sex! The two of them are getting fired up, promising to keep it a secret from their other friends!
