This mistress likes to dominate people and doing it for fun. That is why she chose to dominate as well as degrade this loser. She did it because she did not care what he felt. All that mattered to her was that whatever she wanted was done. That is why she had the loser drink her pee and also endure the punches she threw at him. It was painful and humiliating.
Princess Nikki felt that she had to try pee fetish and she did it. She had always wanted to try it but she had not managed to do so. Today, however, she managed to do it and she had fun. She turned these two losers into her pee slaves. She had lied to them that she would fuck both of them. The lure of a threesome was too strong for them and that is how she turned them into pee slaves.
