Mistress Tiffany wanted info from this loser and she knew the best way to get it was to instill fear into this guy. As he worried about what would happen to him, she would get the chance to do what she wanted. And that is how she came to dominate as well as to humiliate him. She used her boots to crush his head and she also used her cigarette to add on to the pain. Humiliation came in the form of being spat on and being made to lick the spit and when she asked for the info she wanted, he readily gave it to her.
