This guy was too negative for this BBW mistress and she did not want to let him get away with it. She chose to use her weight to deal with him and his negativity. As he smothered him with her big ass, she made him shit his pants and he had no choice but to do what the mistress wanted. He promised her that he would never be negative again.
Lady Cathy wanted to punish this guy for making fun of her weight. She is a big girl who is not bothered about her size. And when guys try to make fun of her, she likes to use the same weight and size to punish them and show them that it is none of their business. For this guy, she trampled him with her ass and sat on him and almost choked him to death.
