Madam Mysteria wanted to make sure that this guy peed himself and that is why she chose to use her dominant tickling fetish to do it. He had told her that he did not mind what she did but when she tickled him, he could not hold on and he had to pee on himself. He was more embarrassed than he had ever been in his life. But she had recorded it and he could not run away from that.
Madam Mysteria was bored and she needed to do some stuff for fun. She had just learned about dominant tickling and she wanted to give it a try. She felt that she could make this guy pee himself as she tickled him and that would be fun to do and to watch. And she proceeded to make the guy do that. He never wanted to go anywhere near her again.
