What I wouldn't give to have had just one college professor that looked like Nina Hartley! Not only does she look better than all of my college professors, she lectures better than many of them also. Nina's Advanced Guide to Oral Sex is broke down into three sections: anatomy, practice, and fantasy scene. The anatomy is pretty basic, but provides a good understanding of the technical terms she uses. She also keeps it very short (around five to ten minutes). The best thing about the entire anatomy lesson was the vaginal puppet she had. It was all I could do to stay in my chair . I kept waiting for it to talk! The practical section goes through many of the techniques for oral sex and is about 45 minutes long. She does a good job of going through basic oral sex, but it is anything but advanced. She goes through vaginal massage, cunnilingous (eating at the Y), felatio (blowjob), and a few other things. The most advanced thing she does is go through a double blow job. The best part of this seemed to be unintentional. Nina was corrected quite often by the girls (and even the guys) on what they liked. It really emphasied the communication between partners.
