This slave did not know his place and he had to learn how to do what she wanted him to do. She felt that she had to put him in his place and that is exactly what happened when she turned him into a foot slave and she degraded him as cruelly as she was able to. He never messed up again after what she did to him as he feared her.
Goddess Mia had a slave who did not seem to understand his place and so she had to remind him. She did not want to put him under any pain so she used her smelly feet to do it. He had to lick them and smell them as she had made them smelly specifically for him. And she threatened to use her cigarette on him if he did not lick the feet. He licked them.
