Mistress Dula had to torture this guy and she did it in a way that caught him by surprise. That is because she made the poor guy eat her shit as well as drink her shit and by the time she was done with him, she had made sure that he learned his lesson the hard way. It worked out well in the end and the poor guy had to make amends.
Mistress Dula wanted to scuttle the plans that this guy had and she made sure that she did so in a way the guy would never forget as long as he lived. That is why the mistress chose to shit on the guy and to make him forget what he had planned to do. As he ate her shit, he knew she was serious and he stopped what he was doing.
Mistress Dula wanted this guy to give her results after he had done the work. He did not do it and he thought she would never notice. When she asked for the results, he cooked them and then gave her. She tried to analyze them and she realized that some things did not add up. She was so pissed that she had him eat her shit as punishment for it.
This guy was envious of mistress Dula and she felt that his envy was misplaced as she was not competing with him or anyone else for that matter. The mistress had to dominate as well as humiliate him which she did without caring about what he did. The mistress made sure that the guy ate her shit after he had refused to do what the mistress wanted him to do.
