Designed to suck and pleasure, these nipple suckers from the BASICS range are strong and effective for incredible suction. Simply apply a little lube to your nipples, depress the bulbs and place over each nipple for the suckers to stay in place. To get going, simply squeeze each bulb and place them over a convenient (and consenting) nipple before releasing. As if by magic - or 'science' - they'll stay firmly attached to each nipple until you decide to remove them. When they're attached the wearer experiences thrilling sucking sensations that increase blood flow, sensitivity and size for subsequent sweater stretcher fun. To increase sensation and suction, just add a layer of water-based lube to the nipple and rim of the pump before use.
