Lady Nicole is not your average mistress. She is a sadist and loves it when others are in pain. She also loves to inflict that pain herself and that is what she was doing today. She did not want to inflict emotional pain today. She wanted the emotional one by degrading her slave. So she made him lick her spit and endure her smoking before she used him as her human ashtray.
Lady Alice had given her slave instructions on what to do. But her slave did not heed them and did not do as she wanted. She was pissed off and had to make sure he never repeated it. She made him lie down on the floor as he explained why he did not do what she told him. She trampled his face with her sweaty feet and used him as her human ashtray.
