When this mistress looked for a way to torture, she had to find a way that the guy would not forget. So she chose to invite her friends to go to her place and help her torture the guy. Her punishment of choice was pee fetish so all the mistresses took turns to pee on the poor guy and when they were done peeing on him, they trampled him.
Mistress Gaia had a score to settle with this guy and she had to make sure she was done with him today. She did not want to postpone it so she used her pee to settle the score. She dominated him with her urine by making him drink it. The mistress had several bottles that he had to drink and he had no choice but to drink it as she promised worse things if he did not.
