Increase sensitivity before play time with the pussy pump. pussy pumps work on a simple principle, suction increases blood flow into the vaginal area, which temporarily engorges the labia and clitoral area, making them much more sensitive to touch and stimulation. the pussy pump plus has a nice big 'cup' size to fully cover the whole pubic area, and the one handed operation makes it great for solo use, or enjoyment with your lover. the suction is nice and strong, and a very flexible hose gives you freedom of movement, and prevents kinking. a quick release valve lets you go as soon as you've had enough.
