There's nothing like disciplining, punishing, a weak pathetic little man.
I can wholeheartedly say that one of my favorite sounds the whoosh of my whips, canes and flogger, and the sound of it impacting on your bare skin.
Impact play/torture has a range of intensities. I measure it as light (leaving the skin pink/red, no bruising/welts), mild (leaving the skin red, with welts, slight bruising), moderate (leaving the skin red, welts, bruising, broken skin) and severe (leaving the skin red with welts, black and blue bruising, broken skin and bleeding.)
I have an extensive collection of disciplinary implements that are kept clean, always.
