Cock and Ball Torture from Wikipedia, The Free Encyclopedia at en.wikipedia.org

Cock and Ball Torture (CBT) is a sexual activity involving the torture of the male genitals.

This may involve directly painful activities such as wax play, genital spanking, squeezing, ball-busting, genital flogging, urethral play, tickle torture, erotic electrostimulation or even kicking.

The recipient of such activities may receive direct physical pleasure via masochism, the knowledge that the play is pleasing to a sadistic dominant.

Section 1, IN PORNOGRAPHY:
In addition to its occasional role in B D S M pornography, Tamakeri (literary ball kicking) is a separate genre in Japan. One notable actress in tamakeri is Erika Nagai, who typically uses her martial arts skills to knee or kick men in the testicles

Section 2, BALL STRETCHER:
A ball stretcher is a sex toy that is fastened around a man in order to elongate the scrotum and provide a feeling of weight pulling the testicles away from the body. While leather stretchers are most common, other models are made of steel rings that are fastened with screws, causing the additional, mildly uncomfortable weight of the wearer. The length of the stretcher may vary from 1-4 inches and the steel models can weight as much as 5 pounds.

Section 3, PARACHUTE:
A parachute is a small collar, usually made from leather, which fastens around the scrotum, and from which weights can be hung. Conical in shape, with three or four short chains hanging beneath to which weights can be attached. Used as part of Cock and Ball Torture within a B D S M relationship, the parachute provides a constant drag and squeezing effect on a man's testicles, moderate weights of 3-5 kilograms can be suspended, especially during bondage. Smaller weights can be used when the man is free to move, when the swinging effect of the weight can restrict sudden movements, as well as providing visual stimulus for the dominant partner.

Section 4 HUMBLER:
A humbler is a B D S M physical restraint device, used to restrict the movement of a submissive male participant in a B D S M scene. The humbler consists of a physical cuff device that clamps around the base of the scrotum, mounted in the center of a bar that passes behind the tights at the base of the buttocks.
