Lady Tanja does not like people who con others. This guy made the mistake of conning her and he regretted it as she punished him. She made sure he learned his lesson by ass fisting him. He was a straight guy and that was not only humiliating, but it was also very painful. And to cut a long story short, he never lived a dishonest life again because he did not want a repeat of that.
Lady Tanja is the kind of person who likes to get even. She feels like it is a waste of her time and energy for her to be mad at someone. She prefers to get even and then focus on other things. And when her enemy messed with her, he was shocked at what she did to him. The mistress tied him up and she fisted him as cruelly as she could.
