Feel the stimulation of these clitoral and nipple pumps. Use the pump to enhance sensations on your clitoris or even on your nipples, increasing pleasure. Place the practical cylinder over your favorite erogenous zone and press the pump to draw blood to that area. You will feel the suction as your clitoris temporarily becomes larger and more sensitive. You can quickly release the pressure in the cylinder by operating the release valve on the pump. The cylinder can also be removed from the pump thanks to a simple closure system, allowing your clitoris to remain suctioned inside the cylinder. Enjoy the unique sensations from the suction power of this easy pump system. Compatible with all types of lubricants. Do not use for longer than 20 to 30 minutes per breast. The set comes with 3 cups, 1 hose, and 1 hand pump. Waterproof and phthalate-free.
