Bigger, harder and more sensitive breasts are just the flick of a switch away with this vibrating breast pump. Sucking onto each nip, it creates a mini vacuum that pulls even the shyest nipple to attention, increasing sensitivity to touch. Pop these breast pumps on shortly before sex and wear them for a few minutes to increase sensitivity to touch. Using the pump for short periods for play and infrequently will not cause any permanent change to your breast, but it does feel fabulous. Enjoy the fun that this 7 speed vibrator brings along.
