Put clamps on your inner lips and then attach string to the clamps and to your big toes, but make sure the string is long enough to reach your big toes, but not all the way if you straighten your legs. Wear them like that, under a short skirt, so your boyfriend can see the string pulling with every step as you walk around the house for a while. Then invite him back to the bedroom and spread your legs wide open for him.
