Madame Marissa did not want to deal with someone who could not remember what he was supposed to be doing. That was not a good thing for her and she had to make sure that he would never forget it. That is why she did what she had to do and she tortured the poor guy as cruelly as she was able to do. She also had her friend help her to punish him.
Madame Marissa was fed up with this guy and she set out to punish him. She settled on doing it in the bathroom and it was a lot of fun for her as she did it. The poor guy did not expect that from her as she had never done it to him before. She chose to spit on him and to ensure that he learned not to offend her anymore.
Madame Marissa needed to crush this slave because she was bored. She felt that he was her source of entertainment and she had to make sure that she did it as well as she could. He was forced to lick her feet and to do other things the way she wanted. He was choked and he was forced to beg her for mercy but it did not help him at all.
