Mistress BlackDiamoond wanted to scare this loser because she knew that if and when he got afraid of her, he would always obey her and he would be scared of pissing her off. The mistress did not care about how he felt. All she was interested in was torturing him which she did with her pantyhose. He was humiliated and he tried to get her to forgive him but she continued with her punishment.
Mistress BlackDiamoond and lady Chanel felt that they had to deal decisively with their boss as he overworked and underpaid them yet their colleagues who did not work as hard as them and who depended on them were paid more. So the mistresses quit their jobs but before they did, they used their pantyhose to trample their boss and let him know that he would regret losing them and that their decision to quit was final.
