That last attribute is the one I love the most - feeling a pulsating load of fresh jizz hit the back of the mouth in a series of distinct spurts really gets me into orbit! I also love a cumslit big enough to get the tip of my tongue into. I should add that it helps if the guy gets really raging hard - some hardons can be disappointingly soft.

And very good luck to his horniness!!!

When I was young and supple I did it all the time - at least as often as jacking. Now I have to be content with someone else's cock erupting down my willing throat! Either source of cum is fine for me!
