The key to bukkake is variety. If you're clever, you can re-use the cum (the cum-catcher technique, or her rarer and messier cousin the cum-puker technique.) It's important to use varied methods to get the most out of it, but you won't outdo Moodyz anytime soon, and personally I think that bukkake isn't really bukkake unless it's Japanese. Like bourbon isn't really bourbon unless it's from Kentucky, or champagne isn't really champagne unless it's from Champagne. Nothing wrong with sparkling white wine; some of it's really good, but, well, you were talking about the importance of positions...
