Lovers of anal stimulation will swoon for the B Balls, the silicone anal plug that reacts to your motions. Rotating inner weights follow the movements of the user, adding an extra kick during sex. The narrow base is 100% safe and secure and does not block access to any erogenous zones. Suitable for any gender. You’ll also love B Balls for solo play, worn invisibly under clothes for all day subtle stimulation, or work them into your masturbation routine to take your private orgasms to a more intense release.
