Mistress Tulip valued her man and her relationship. That is why she was pissed at this guy for wanting to make her cheat. She did not feel like it was worth it and the guy was also not worth it. She had no reason to do it and she had to avoid temptations such as those this guy was giving her. She had to punish the guy and she did so using her shit. The mistress had him eat her shit as punishment and he never tried that nonsense on her again.
