Human Punching Bag

I have my slave strapped from the ceiling using him as my human punching bag for my workout. I wear a pair of skintight black leather pants an a sexy black bustier. I have a lot of joy hitting my slave again and again so not long til he is gasping for air in agony. He starts sweating and looks like loosing his mind or consciousness, but I am not done with him yet. I grab one of my fav whips and whip his fat arse not holding back until he is completly fatigued.
