This mistress needed to dominate this loser and she had her do that as cruelly as she was able to. The girl did not want to do anything she was told but the mistress made it very clear that if she did not do it, she would get a worse punishment so she had no choice but to do what the mistress wanted him to do. It was a lot of fun for her as she degraded her.
This mistress noticed that she had a slave who loved being dominated and she felt that she could do it to him often because she also loved to dominate. They had found something they could bond over and it did not have to involve a punishment. So the mistress facesat the guy and she had him smell her butt and he loved the smell and was turned on but he knew sex was off limits for him as he was not in her league. So he rubbed one out.
