Mistress BlackDiamoond was tired of how her sister let imbeciles walk over her and take advantage of her. She had to teach her sister how to stand up for herself and how to punish them when they messed with her. So she asked her sister to bring one of them and she showed her how to use muddy boots to dominate him. She waded in mud and made the loser lick the boots clean before asking her sister to try it.
