I like it very much to raise the tension with my slaves and I can do this literally. By attaching live wires to clamps or sticking pads which I have placed on your nipples, cock and balls or labia I can tingle you properly.
Slowly I raise the current further and I enjoy seeing you writhe in agony and pleasure. Pleasure? Yes indeed, because by the electrical stimulation of your genitals I can give you an explosive orgasm. If I do so is another matter. You have to earn this of course!
