This guy was too unreliable for mistress Ambra to stomach. And she knew that if she did not do something about it, the guy would end up messing her up and so she punished him to make him stop that behavior. The mistress used her sneakers to trample him and after the head to toe sneaker trampling, the guy learned his lesson and he acted and behaved accordingly since he did not want a repeat of what he felt.
This guy thought it would be funny and naughty to trample mistress Ambra but she did not like it. Instead of the reaction he wanted, the mistress turned on him and she used her sneakers to trample his hands. She did this because she wanted him to never do that again to anyone else because it was not a welcome move and could be considered as assault. He learned his lesson.
Mistress Ambra wanted to test this guy's pain threshold but she did not know how to do it. She felt that the best way to do it was to use her sneakers to crush his chest and trample his dick as well. He was lucky she did not venture into his nuts as that would have been one hell of a painful experience for him. He was lucky she did not want him to cry in as much as she wanted to test his pain threshold.
Mistress Jocelyn was tricked by her friend but she found out. And since she is one of those who do not like jokes, she had to punish the friend for what he did. So she trampled him on the head and on his chest as he lay on the floor. The poor guy cried and begged her for mercy but she remained quiet as she went on trampling him painfully.
