Every now and then BBW Lady Cathy uses her slave's face as a stool. She sits on it, while watching TV or reading a book, and smothers his face with her glorious ass that he worships. And if the little loser starts wiggling, she gives him a good smack or two, he must realize that he will breathe only when she says and he must show his appreciation that she even lets him come to such close contact with her Goddess' body!
