Mistress Alina was bored and that was when she found use for this guy who had been stalking her. She let him come to her house and she turned him into her human pony. It helped that she was wearing a bikini so he thought she was interested in him. But he was turned into a pony and she rode him for hours and even whipped him when he strayed.
Mistress Jamie-Kate did not have anything better to do so she humiliated her slave for fun. She turned her slave into a human pony. She rode him and even pretended to feed him by making him smell her shoes. She tied his shoe on his neck and let it dangle to his nose and he had to smell it as she rode him like a pony. It was humiliating for him but fun for her.
