The mix of pleasure and pain is H.O.T. And a simple way of giving Mistress pleasure through a bit of self-administered pain is a zipwire: pegs, clipped to flesh, connected by a rope. Then pulled off like a Band-Aid.
Sometimes across the nipples, or balls, cock or inner thigh. Clip and pull – and that lovely feeling that just makes you need to touch yourself. Just the eight this time. How many next time, ma’am?
