Rock hard, ultra sensitive nipples and heightened arousal are just a touch away. With the push of a button, the suckers adhere perfectly to the skin with a strong automatic suction seal for hands free fun, just place the transparent cups over each nipple, power on, and watch them grow. Powerful multi-function vibrations with separate controls for each cup raise the intensity even higher, while simple controls make them incredible for solo or partner play. Requires 2 AA batteries, not included. Measures 2.25 inches wide.
