Lady Vampira and her friend chose to use foot domination to send a message and it had to be a cruel message. The mistresses trampled this guy and they did it as painfully and as cruelly as they were able to before they caged the guy. He was forced to feel pain and to experience humiliation before the mistresses were done with him. He never messed with them after what had happened.
Lady Vampira could tell what this guy was trying to do to her. He was a conman and was trying to con her but he did not know she could see through his scheme. The mistress was angered by his behavior and she played him. He thought he was succeeding in his scheme but she was luring him to her house where she turned him into a foot slave and got him to lick her feet and her shoes.
