If not inside then I like to do the porn money shot and do it all over the boobs. Nothing hotter than a girl panting after hot sex with your load dripping off of her chest.
^^ I'm with Pony, but any where it goes is fine with me. The best is when I have a hand full of hair and she can't move her head, then blow all over her face from about a foot away. It covers her eyes, mouth and goes up her nose, that's hittin' it!
She'll just get diarrhea. Happens with my gf everytime the next morning. Then they swear it's the last time and next thing you know, she's begging for anal... lol
