Use this automatic, rechargeable pump to increase blood flow to your most sensitive regions and heighten arousal. Choose between the two included cup sizes, position it over your vulva or breast, and apply a bit of water-based lubricant to help create the secure seal needed for effective suction. Once in place, the pump's suction modes draw blood into the area, enhancing fullness, sensitivity, and temporary swell. You'll feel gentle pulling sensations as the integrated tongue stimulator adds rhythmic flicking for intensified pleasure. Designed for easy, hands-free enjoyment with consistent, reliable power.
