These nipple suckers can be used on any body part you want suction and to increase sensation after removed. Just squeeze the air out and apply it to the skin so they can suck the tissue into them as they open back to full size. Some people like to add lube or saliva at the base to help them seal. The smaller suckers mean a lighter suction than larger models. Made of PVC.
