Mistress Gaia did not feel ok with the way her slave was behaving and she had to show him what she was willing to do to him if he did not change. So the mistress chose to use her cigarette to punish him. She added her ass to the mix of punishments and she used both her ass and her cigarette to choke him. He was scared and humiliated at the same time and he changed.
Mistress Gaia wanted her slave to change and be hardworking so the mistress used her strangling fetish to scare him and make him receptive to the idea of being hardworking. By the time she was done choking and dominating him, he was not only receptive to the idea, but he embraced it and promised to be the most hardworking person he knew. And he kept his word as he did not want any more choking.
