This mistress loves wearing jeans. Besides looking good in jeans, she also wanted to use it to facesit on her slave. Her slave was forgetful and it pissed her off as he did not seem to be trying to change that or improve. So she had to facesit on him and teach him a lesson he had never been taught before. That is why she opted to facesit on him with her jeans so that he could feel the pain and choke a little too.
