This mistress has a thing for ponies but she stays in the city and she cannot have a pony. She lives in a tiny apartment that is barely enough for her stuff let alone a whole horse. But she did not give up her dream of having a horse completely. She turned a slave into her human horse and enjoyed riding him all over her house. She whipped him when she felt he was slacking off and did it while she was wearing her G-string so as to motivate him.
