Lady Dominika was being seduced by her professor and she did not like it. She felt it was unprofessional of him but she did not want to report him to the school authorities. She felt that the best way to teach him a lesson was to make him eat her shit. She forced him to eat it and drink her pee. That is how he learned his lesson the hard way.
Lady Dominika does not like it when her interests are misrepresented. That is what this loser did today and the mistress had no choice but to punish him so that it was a lesson to others and so that he did not repeat the same mistake. The mistress fed him her shit and ensured that it was the only food he ate for a day. He also drank her pee.
