This mistress knows how to use her big tits to get what she wants. She used them to lure this guy. He wanted to play with them and he was turned on as she used them to bait him. And after he had taken the bait, she used the same big breasts to choke and smother him. He could not believe that the thing that he loved and wanted was the same one used to dominate and humiliate him.
This mistress needed an overdue debt paid. It had been long since he was supposed to pay it back and she felt that she had given him more than enough time to pay back. When he did not, it was up to her to teach him a lesson that no one had ever taught him. That is why she cruelly used her smothering femdom to do it. He paid her that same day.
