Two girls tie a string to their panties and fix their hands with restraints. Ask her boyfriend about her private matters from her "embarrassing questionnaire", and if you answer 5 questions first, she will receive a prize of 1 million yen! If you make a mistake, a weight will be hung on the string, and the panties will bite! The game ends when you give up because you can't stand the pain of biting in on the way!
