Lady Krasaviza wanted to teach her slave to be a human pony for her. She had even gone ahead and bought riding boots which she wore when she taught him. But he did not learn what she wanted him to learn so the mistress trampled him with the same riding boots. In addition to that, she also kicked him to send a message that what she was asking him was an order not a request.
Lady Krasaviza likes to experiment with different punishment methods. Today she chose to cage her slave when he messed up. She even made him wear a diaper so that he would disturb her with calls to go to the toilet. After she felt he had stayed in the cage long enough, she got him out of it and she turned him into a boot slave. He licked her boots and got spat on before she felt it was enough.
