I've tried various postions over the years. The whole cock over lips is really uncomfortable...not to mention you can break your neck doing that. I prefer just laying down on back and going for a good long wank and when you feel like coming, do it and not care about where the come flies. Or squirts.
The best wank i ever had, I blew every ounce of jizz into my mouth and every powerful squirt into my mouth just sent me way over the edge. I'm pretty sure that I broke my own rules, but it was nice, and I didn't mind gargling my own cum. I was my own Queeny Love

.
Now I just slip on a few pairs of pantyhose and stockings, lay on my bed and let the cock blast wherever when I want to taste cum. It may not feel as good as getting your tonsils blown out by cumshots, but it still feels nice.
I still soak myself pretty well, even if most of the cum goes everywhere but my mouth. :O
