Lady Tassia had told this guy what her expectations were from him. But the guy did not do anything about it and she was very disappointed in him. The mistress had to degrade him and she did so using her ass by choking him. When she was done choking him with her ass, the mistress made him lick her again and this time he did not disappoint the mistress as he did everything as per expectations.
Lady Tassia did not have much to do and she needed a way to pass time. So she chose to use her ass worship fetish to pass time. She had this guy who had a fetish for asses to come and lick her ass as well as endure her facesitting. He also smelled her ass as well as her farts and the mistress had a great time at his expense.
