The core of Taormino's lessons is "Fellatio should not be a selfish, one-sided act. It should be mutually pleasurable."

The basics are covered in a workshop, with an audience of women watching Roxy DeVille, an enthusiastic, loving oralist, pleasure Christian. Tristan, at their side, gives tips on enhancing skills.

Three more couples demonstrate, in private, techniques that get increasingly more advanced.

Kaiya Lynn, with Alec Knight, shows how to tease: "As you build his anticipation, you fuel his arousal. … Eye contact is an important part of a good blowjob."

The instruction becomes more detailed. "Using your hand is not cheating. … Think of your hand as the extension of your mouth. You want to strive to get the two in synch."

Pretty Lindsey Meadows, a loving, committed cocksucker ("You gotta really, truly love it"), determines what Marcos Leon likes, then expertly gets him hard. Their scene is very erotic, both of them extremely turned on.

For still more advanced, porno-centric stuff, like deep throating, Taormino turns to Adrianna Nicole with Knight. This is the first time we see the man standing with the woman on her knees, a position that's standard in porn.

Each couple shows "what oral sex, or a combination of oral and manual stimulation lead to, which is ejaculation."

Bonus scenes in the extras cover more arcane subjects like uncut dicks and prostate stimulation.
