Strap-On Fuck Toy

My slave has been enduring my ministrations all day and is quite worn out, but I want to make him my strap-on toy. I restrain him throughly and begin to pentrate his ass. Slowly at first, then increasing in speed and severity until he is crying beneath his rubber hood. I almost knock him over from fucking him so hard, but grab him and pull him back onto my cock for even more vicious pounding. All slaves must learn to endure for me.
