The slave girl is trained to get horny by being whipped. Either when she is crudely bent over, given a ruthless, cruel and deep round with a cane from a position of absolute authority, and where her pain is unbearable and her body marked. Or by a long, soft, gradually growing well aimed caning/whipping where the right body parts are warmed up as we go along. In time this, too, gets a bit hard on her. Today, she was forced to cum close to orgasm with the wand, and then trained to stay close during a round of semi-soft whipping. Back and forth between wand-whipping-wand…. 1, 2, 3, 4 times and more….her owner was not satisfied until she kept her state of arousal right on the edge all through the whipping. she was a good girl with a reddened ass and was eventually allowed to cum twice.
