Kinky women in collars and bondage

It's all fun and games, even if sometimes pain is mixed with pleasure. Of course we're talking about consensual bondage and discipline, BDSM, ropes, collars, nipple clamps, spankings... sometimes discreetly indoors in a private setting or a club, on other occasions in a forest or a park setting. How many subby people looking at this gallery have been tied up or collared for a kinky sexual thrill? How many of you have done this to somebody else? Do some of you make domination or submission a regular activity?
