This mistress was out to smash and smother this guy and so she did it with her big ass. She knew that she would be able to cover his entire face with her huge ass and that way, he would choke the way she wanted. The result was that the guy feared her and that way, she was able to achieve what she wanted to when she set out to punish him.
This mistress has a big ass and she does not like it when anyone tries to make fun of it. This guy did and he lived to regret it because she was so pissed at him that she used the same ass he was making fun of to punish him. He was ass smothered and made to choke and beg for mercy. The mistress did not care what he felt. He had to learn never to do that again.
