Mistress X and mistress Dynamo are strict people. They had a new slave and he was not the sharpest they have ever had so they were a bit frustrated with him. But they do not give up so they had to beat him up and trample him to teach him how they wanted things to be done. So anytime he messed up, he was trampled by both of them and he was made to learn from the pain and try to do and to become better.
