Tie a rope or string to the back of the panties through the leg holes. Run the sting up over your shoulders and pull a tight wedgie. Then fasten the string to your nipple clamps. Hopefully this is along the likes of what you are looking for. If you have extra string you could tie it to your wrist so you have to keep your hands near your nipples or risk pulling the clamps and the wedgie.
