Education With Slaps

My slave will now learn about indignity. I tie him to a chair and make him expose his ugly face to me. I want his chin on the backrest - ideally placed to get his face slapped! One slap after another hits his face - but the slave cant stand it. With the power of my voice and slaps I train him brutally. He has to keep his chin on the backrest so I can continue to hit him!
