Rock-hard, ultra-sensitive nipples and heightened arousal are just a touch away. With the push of a button, Swell adheres perfectly to the skin and provides hands-free pleasure with its powerful automatic suction function. The transparent cups are simply placed over the nipples, turned on, and left to grow. Powerful multifunction vibrations with separate controls for each cup further enhance the intensity, while simple controls make Swell an incredible choice for solo or partner play.
