Mistress Valeria had a new slave and she did not want to let him get away with messing with her. He needed to know that she was his boss and so he could not do whatever he wanted or say whatever he wanted to her. She taught him a painful lesson as she trampled him and then kicked him in the nuts. He regretted his mistakes and he never repeated them.
Mistress Valeria had given this slave some time for him to come to his senses and stop being rude to her. She wanted him to realize that he was the slave in the relationship and he had to act accordingly. But he never came to his senses and so she had to make him understand his position and so she used her leather gloves to gag him and to choke him until he understood.
