Only her anus

My boss is so attractive and sexy. I'm her assistant and she's pleased with my work but she's a very strict and professional business woman. She's aware that I like her but she's only into men that are as or more successful than her. She admits that I'm handsome but she can't be with me. The only thing she can do for me is let me eat her anus when she's in the mood. She has such a clean beautiful asshole. I eat her anus with so much pleasure. Occasionally she'll masturbate as I'm doing it. Her vibrations and moans as she orgasms feel good all over my face as I am sucking on her anus.
