Lady Nora needed to put this slave in his place and she did it with her female domination fetish. She used her smelly feet to do it and he was humiliated and tried to get her to stop but she did not. All she did was laugh at him and double down on what she was doing to him. He knew that she was never to mess with after that.
Lady Nora and her friend mistress Kim Judge wanted to humiliate their landlord and they felt that the best way to do it was to dominate him and to tie him while he was naked. He was wrapped in cling film and he was humiliated by the mistresses who did not want to let him get away with anything he did. That is how the guy changed for the better.
