Mistress Natasha was not fat but her boyfriend called her fat to piss her off knowing that she would be hurt by that remark. She was clever enough to know the real intention of what he was doing and that is why she chose to trample him and make sure he never did such a thing again to her or to anyone else for that matter. He learned the hard way.
Mistress Natasha did not want a clueless guy anywhere near her. Not only was this guy clueless, but he also had the balls to go to her hotel room wanting to hang out. She was pissed by his audacity and she had to deal with him so that it never happened again. The mistress did this by trampling him with her high heels and he never thought to do such a thing again.
Mistress Natalia does not like her slave going to her bedroom. She was pissed when she found him there. She had to make sure he never did that again. So the punishment had to be severe but before she punished him, she first of all told him of his mistake and what he should do next time to avoid being punished. She then trampled him using her shoes and with her bare feet before she let him go.
Mistress Natasha asked her slave to play the piano for her. But he played horrendously and she was pissed off that he was so terrible at it. She decided to give him an incentive to learn to play the piano. Instead of sitting and playing the piano, she played while standing on him. She crushed him rhythmically as she played and made him endure all the pain that her shoes and weight put on his bare upper body.
