Princess Natalie felt that she needed to dominate this loser with her big ass and she did it because she could not because he had done anything to her. The mistress made it look like she was having fun with him but in fact all she was doing was having fun at his expense. He regretted why he had pissed her off but he learned his lesson the hard way.
Mistress Alexis wanted to find out whether ass smothering a guy's dick with her ass would be as painful as doing it with her feet or even with her hands. The mistress flirted with the guy and she made him think that she wanted to mess with him. Then she sat on his dick and his balls then watched for his reaction. It was slow to come as he tried to endure it but when it became too much, he had to ask her to move.
