Lady Scarlet had observed this girl for some time and she did not like what the girl did. She felt that the girl was trying to mess with her man and she had to put an end to it. Her man was not giving in to her as well. So she cornered her, tied her up, trampled and choked her with her smelly socks to teach her a lesson she will never forget.
Lady Scarlet knew what she wanted from this loser and she had to get it. The mistress used her socks which she made sure were smelly and dirty and she used them to dominate the loser. He learned the hard way that he could not piss her off and get away with it. So he did what she wanted as he did not want to continue being degraded using smelly socks.
