Mistress Enola noticed that this guy was a loudmouth and she knew that it was up to her to deal with him. She had to slap the shit out of him and she did it after she had made him lick her feet. He cried as the mistress did her thing on him and he begged for mercy but the mistress was not interested in any of the things he wanted.
To better punish her slave, this mistress knew that she had to do what she had never done before to her slave. And that is why she made him sit on a chair and then she tied his hands behind his back leaving his face for her to slap like she wanted. He tried to cry but she did not care about his cries of the pain he was in.
This guy wanted to work with mistress Enola. She was not opposed to the idea until she learned that he was clearly incompetent. She was not going to jeopardize the success of her project by working with him so she slapped the crap out of him and she made him quit. That is because she did not want to have to fire him. He did not have an alternative but to quit.
