When mistress Annalise realized that her perverted cousin wanted to sleep with her, she had to make sure that he changed. And to do that, she had to use her shit to make him know that she meant everything she said. He had no choice but to do what she had instructed him to do. And since he was afraid of her after being made to eat shit, he changed.
Mistress Annalise does not tolerate any nonsense. Her boyfriend pissed her off and she had to punish him. She had noticed he took a lot for granted and that did not sit well with her. She had to ensure he learned his lesson and that he learned it the hard way. So she made him eat her shit and swallow it. That would stay with him forever and he would not repeat his mistake.
Mistress Annalise orders her slave to the floor and tells him to lick her soles clean. Once he's done with that, it's time for him to accept her massive load of shit. She squats right over his face and tells him to open his mouth. Once he does, she lets the creamy shit flow out of her and fill his mouth. She then tells him that he has to lie there with it in his mouth until he swallows it all and leaves the room.
