Mistress Zora makes her slave pony run arouind her in circles. She examines the quality of his movement and realizes how ridiculously fat he is. That must change! She gives him a fat-burning training session. But enough of the warm-up! She now increases the level of difficulty and even sits down on his back with her denim ass. The little slave pony now has a lot to do because he's carrying around his riding mistress while continuing to follow the instructions of his dominatrix, Mistress Zora.
