No knocking necessary.
If I'm sucking your cock, I'm doing so with the intention of milking every last drop from it. It's unnecessary to warn me that you're going to cum though I won't say it isn't always unwelcome. Sometimes, if someone has been saving up and about to shoot a really big load or they cum with a lot of force, a quick warning allows me to ready myself for my reward. Nothing worse than getting caught off guard and losing any of that delicious nectar.
I also say that if you've sucked more than a few cocks, you usually can tell when a guy is about to unload without his having to say a word.
