Serena: Today I flatten the slave face under my feet. Today I take my breath away with my beautiful feet. I sit on the body of the slave and flatten his lungs with my ass. It is already difficult for him to breathe. Then I press the two soles of my bare feet on his face, mouth and nose. After that he has the feeling that he can not breathe under my feet. I pinch his nose between my toes and let him wriggle under my weight. This game is fun for every mistress.
