Mistresses don't have to have a particular reason to want to whip their slave. If anything I think it should be done regular to jeep them in their place. There's nothing worse than a slave turning cocky and disobedient and in My experience a good whipping, corporal punishment or some form of discomfort always helps them know who their Superior is. This slave hasn't been misbehaving but when I feel the urge I know I've always got slaves to hand. I warm his back up nicely with a leather flogger then continue on by using my ultimate favourite toy - The Weltinizer. You do not need any effort at all while using this as its so sharp and makes the kind of contact with the skin I love
