Lady Amy and lady Grace had approached this lawyer to represent them in a case but he lost it and they were mad at him as it seemed like a straightforward case. They had to make sure he appealed and he won and that was why they ball kicked him and nut tortured him. They knew the pain would be a powerful motivator for him and he would do what was necessary to win.
Lady Chrissy wanted to dominate this guy and she did it in a way he never expected. The mistress teased him, tied him up and then had him lick her tits. When he was done doing it, she kneed and kicked him in the balls and told him it was because he had not licked her boobs well. She also made him lick her feet and even gagged him with the same foot he licked.
