This mistress wanted to make sure her husband was never tempted to cheat again. She forgave him the first time but had to make sure he had an incentive never to cheat again. And that was whenever he did something fishy, she would trample him and make sure he was in lots of pain. She would even trample his cock and make him cry and beg her for mercy. That taught him the straight and narrow.
Mistress Sarah was mad at her slave for telling her secrets. She could not let it slide like that. She had to do something. She had forgiven him one too many times and this time, he had to pay for all those other times. She made him lie down and she used her high heels to trample him and make sure he was in the kind of pain she wanted him to be in.
Mistress Angelique wanted to show this slave what price he would pay if he ever snitched on her or wronged her. She wanted to do it in advance so that he would not be tempted to do it and that if he ever did it, he would know what exactly he was getting himself into. She trampled him with her high heels and made him cry like a baby at the pain she inflicted on him.
Madame Marissa wanted to exercise her legs. She did not want to go to the treadmill or ride a stationary bike. She wanted to move her legs around but she did not want to take a walk. So she thought about it and realized she can achieve the same by trampling and jumping on her slave. She called him and made him lie down and she had fun exercising on his body.
