Madame Marissa wanted her slave to learn his lesson the hard way so she forced him to lick and smell her sweaty and smelly socks. She did it on purpose so that she could choke him and teach him a cruel lesson. He was shocked as she had never been that cruel to him before. And that was why he had to change as he was not sure what she would do to him next.
Madame Marissa could not believe the fact that her slave had thrown away some of her valuable documents. He did not bother reading what they were and he had messed her up big time. She could not let him get away with it so she punished him using her feet and her shoes. She trampled him and choked him with her socks. He had to be careful next time and the punishment made sure of that.
