Lady Stefanie told her slave what he had done and why she was pissed off at him. The mistress felt that he had to learn his lesson the hard way and she made sure that he knew what she was willing to do to him if he did not follow her instructions. Her instructions were for him to lick her feet as well as her soles. He did it all.
Lady Stefanie is a big flirt and she wanted to make sure that this guy was into her even though she did not want to do anything sexual with him. All she wanted to do was to make sure that she turned him on him as much as she was able to before she left him high and dry. And that is exactly what the mistress was able to do.
