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 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 Swell incredible for solo or partner play. Kink by Doc Johnson is an exciting collaboration with Kink.com to create a collection of high-quality authentic fetish items suitable for long-term practitioners and new initiates alike.Colour: ClearFlexibility: SlightFor Who: BothFeatures: Phthalate FreeMaterial: Skin Safe RubberBrand: Doc JohnsonPower: 2 x AA (Included)
