Skin Diamond fucking in the desk with her small tits

As Professor Lawrence is offering an extra credit assignment days before his class's midterm, he becomes distracted: one of his students is playing with herself under her desk. He keeps her after class to discuss it, and she admits that she was looking at a porno mag instead of the 18th century literature material. Jack doesn't want to go to the administration about it '? and his sexy-ass student persuades him to keep it that way by letting him fuck her with his giant cock!
