My roommate and I are played one social game and I bet with her if I win, her feet must be tied and tickled. She was convinced that she would win but she lost at the end and she accepts my condition but asked me to do not to use evil tools, but I can not promise to I not use my favorite tool. She lies on the bed with face down and her legs are tied with a belt and her toes are tied too. I seat on her legs and her feet are totally under my control. I start with my fingers but I can not avoid electric toothbrush, electric flosser, comb and hairbrush when her bare feet are so helpless.
