Mistress Valeria wanted to control this guy and that is why she chose to pee on him. She felt that it was important for her to do it and she did not hesitate to do it. By the time she was done with the guy, she had forced him to drink her pee and she had him lick her pussy in addition to smelling her farts. He could not do anything about it.
Mistress Valeria did not like how disrespectful this guy was and she had to teach him a lesson that she felt that no one had ever taught him. That is why the mistress peed on a bowl and she forced the guy to drink the pee from the bowl. He was shocked at what she did to him and he realized that he had to stop being disrespectful to her if he was to avoid that humiliation.
Mistress Valeria was bored and she felt that peeing on this loser was a very good way for her to pass time and have fun. So she went full throttle at him and she made him do things the way she wanted. The mistress scared the shit out of him first before she ordered him to drink her pee knowing that he would not have the balls to disappoint her.
