This guy admired this mistress' big ass and he wanted it all to himself. She could tell what he was on about and she had to dominate him. That is why she chose to use her big ass to dominate him. She turned him into an ass licker and he licked it all including her asshole. She did not care what he felt as she did what she did to him.
Madam Tulpan has never had her asshole licked. She has only heard that other people got theirs licked and she envied them. She wanted hers to be as well and she was so determined to have it licked that she had this guy do it. He was turned on and promised a good time but it never happened as the mistress was lying to him to get him to lick her asshole.
Madam Tulpan loved to get her asshole licked and she had this done weekly. It was not a punishment for her slave. It was just something she liked to be done to her and it was part of the job description for her slave. He was shocked when she first asked him but he got used to it and he knows he has to do it once a week. In fact he has become a pro.
