There’s no satisfaction purer than gagging a bratty sub, or forcing a partner into submission with kinky restraints. A mouth bit or ball gag is utterly dehumanising; it removes a sub’s ability to communicate. A collar signifies subservience and obedience, a blindfold heightens all the other senses and increases the anticipation and sensations of spanking, nipple clamps are sadistic restraints are totally immobilising.
