In nature sex is always intertwined with power, and there is usually a sexual aggressor and another on the receiving end. In bondage xxx, this relationship is pushed to the extreme as the submissive party is tied up with rope, handcuffed or hogtied in the nude and thus rendered completely powerless, helpless and defenceless. In xxx bondage sex the submissive and masochistic may be gagged, whipped or submitted to water bondage, as pain and humiliation become pleasure in this controlled environment, where that leather collar is a clear indication that the sub is a sexual pet, and ultimately a sex slave.
