This calls for punishment! This stupid slave hasn't correctly understood his task. He was supposed to lick all of Princess Serena's shoes completely clean. There shouldn't be a stain on her boots afterwards, but it seems he has overlooked something. Princess Serena has noticed, of course, because she notices everything. Her boots are still dirty! The slave will now have to be punished. She strikes his back and ass firmly with a crop, landint it with a loud crack! That's the way it should be because a useless slave deserves nothing else!
