Butt goddess Tristan Taormino melds thorough, accurate information and hot, authentic sex better than anyone else in porn today. Tristan built her anal empire teaching how-to workshops all over the world, and this must-have video captures her thorough presentation on anatomy, preparation, relaxation and more, all simultaneously demonstrated by her two comely assistants Lorelei and Ariel. After the workshop, male/female couples put the techniques into explosively orgasmic play, using toys and lots of different positions. The DVD offers on-screen graphs, along with the option of watching with or without instruction narration, and a bonus enema how-to scene.
