This mistress could tell that her slave had messed up. Even though she did not know what he had done wrong, her instincts told her that he had. And she punished him as a result. The mistress did not tell him why he was being punished, but she did it all the same. She got him to lick her sweaty nylon stockings and to do the same to her shoes.
Madame Marissa had expensive nylon stockings which she found missing. She did not ask her slave because she knew she had a hand in the disappearance of her stockings. So she went and looked for them and she found them in her slave's room. She trampled him painfully and cruelly to teach her not to steal anything of hers again. She even choked him as she trampled him in the neck.
