Mistress Natasha was angered by what her slave had done. He had taken a video of her taking a shower and was masturbating to it. She was so angry at him and she did not want such a pervert in her house. She smothered him with her ass and she made it as painful as she could so that he would never be tempted to do it again. He never did.
Lady Amy caught her slave handling food with dirty hands and she was angry. She did not want to fall sick on account of his negligence so she punished him. She did not want him to repeat his mistake so she sat on his face and she smothered him painfully. He cried and said he had learned his lesson but she only let him go when she believed he had truly learned his lesson.
Mistress Amanda had never punished her slave before and he did not know whether she was capable of doing that. So he took a lot for granted. She was pissed and she had to teach him a cruel and painful lesson. She used her ass to do it. She smothered his face with her ass and she choked him in the process. She also farted on him for good measure.
