Two girls tie a string to the panties and fix both hands with restraints. Ask your boyfriend about private matters about her from the "embarrassing questionnaire", and if you answer 5 questions correctly first, the prize money will be 1 million yen! If you make a mistake, a weight will be hung on the string and the panties will bite into it! I couldn't stand the pain of biting on the way, and when I gave up, the game was over!
