Rubbers (gags) are specific deprivation erotic aids used in BDSM practices. The gag usually takes the form of a ball with a leather belt threaded through it with a buckle for tightening. This ball must be taken into the mouth of the submissive and the buckle is tightened behind the head by his dominant counterpart. The sub thus has difficulty breathing and is limited in his ability to verbally defend himself or respond to punishment.
Gags come in many forms, some are simple leather ones, combined with steel, which spread the mouth and allow even full penetration of, for example, a penis into an open and helpless mouth, … Others contain inflatable pins that uncomfortably stretch the submissive’s mouth and make breathing difficult, or make him or her swear heavily.
