Mistress Amy is a strict person. Her slave knew that but he still messed up. She felt he had done it on purpose to test her and she gave him what he wanted. She whipped him and she turned him into her human pony as punishment. She rode him and she trained him to carry her all over the house. She did not care how heavy she was and how he was laboring to carry her.
Mistress Gaia had always wanted to have a pony but she lived in the city and in an apartment so she could not have one where she lived. But she could have a human one. She turned her slave into her human pony and she enjoyed training him to be her pony within the house. He was to transport her anywhere she wanted to go within the house and when he did not meet her expectations, she whipped him.
This slave was not meeting mistress Sheena's expectations of him and she was pissed. She had to teach him a lesson and she forced him to do as she wanted. To signal how serious she was, the mistress forced the loser to be her human pony and she rode him in the house. She even whipped him when he got tired and that got him going again. It was brutal.
