Mistress Celine wanted to ride a horse but she did not have one and she did not know how to do it. She was also scared of horses despite wanting to ride one. She settled on a compromise which was to turn her slave into a human pony and ride him instead. And that is what she did despite how painful and cruel it was to her slave who had never done it before.
Mistress Hailey loves to punish. She always looks forward to when her slave messes up so that she can dominate and punish him. That is what she did today. She was dying to try pony play fetish and she did so when her slave messed up. She had a great time riding him all over the house and she nearly broke his back. He begged for mercy but she ignored him.
