Controlling my slave's breath with facesitting

Description: "do you feel like the luckiest slave in the world?" my slave is treated to some intense facesitting and queening, provided he keeps his mouth closed at all times. he is not to move a muscle - he is to do exactly the opposite of what a man would want to do in his position. he is teased with my lingerie and ff nylon stockings and has his breathing regulated by my ass. a forgotten clip from 2020.
