Device used in BDSM play, specifically in cock and ball torture, that restricts the submissive movement.
Used in BDSM role playing, this is a specific device used to restrict the submissive.
Usually this includes a testicle cuff, which clamps around the base of the scrotum. A bar in the middle passes between the thighs, around the buttocks, which forces the submissive to have his legs bended in a forward motion.
Moving to straighten the legs will cause the bar to pull the cuff, and scrotum, causing extreme discomfort.
There are medical considerations when using this device, for prolonged periods, or even short term.
Permanent physical harm can be done.
