Have you been focusing on pleasures below the belt line? M2M's sensuous silicone nipple suckers create a gentle vacuum to get your nips fully erect and sensitive to the touch. For stronger suction and an air tight seal, try lubricating them with a water-based personal lubricant before applying. (Keep in mind that body hair can reduce the seal.) Made from 100% silicone, these Nipple Suckers are phthalate and latex free.
