Two girls have strings tied to their panties and their hands secured with restraints. From the 'embarrassing survey,' they ask their boyfriend private things about her, and if he answers five questions correctly first, he wins a prize of 1 million yen! If he gets one wrong, a weight is added to the string, causing the panties to dig in! If the pain of being dug into becomes unbearable midway, and they give up, the game ends!
