Mistress Carla was broke and she needed to make more money than she was currently because she had a lot of needs and responsibilities. So she devised a way to make that happen and the best way for her was to tease her boss and to have him give her a raise. That was easy for her as she is super hot and has an ass to die for and her boss had a thing for her. So she made it work.
This guy was attracted to mistress Carla's hot ass and she used it to bait him. He could not help but get turned on as she put on a show for him. He checked out what she did with her ass and with her asshole and he wished he could slide his rock hard dick into her tight asshole. But instead of doing that, she teased him and denied him besides farting on him.
