Kali's teeth bracelet

Named after the Hindu goddess Kali, the Kali's teeth bracelet is a form of chastity device (see chastity belts) for men. Consisting of a metal ring with blunt spikes on its inside surface, it is locked around the shaft of the flaccid penis. Made in size so that it is unable to come off even when a man is not aroused, should he become partially erect, the spikes will press into the soft tissue of the penis, thus causing pain without damage and preventing the male from becoming fully aroused.
