When this mistress noticed that she was dealing with someone who bullied her slave, she knew he had to learn his lesson so that she did not keep having a high turnover of slaves. She wanted her slave to settle down and that meant humiliating this guy and making him stop mistreating slaves. So she made him eat her shit as she had realized he was the one behind her high turnover of slaves.
Mistress Mia wanted to cuckold her boyfriend since he had cheated on her. But she knew she had to strike fear in him first and she did it with her shit. She had him eat her shit and once he believed that she was cruel and brutal, she then cuckolded him as he believed that she would not tolerate any dissent from him. She had paid him back for what he had done but hers was colder than his.
