At the end of it, she gave me a hand job. While I was ejaculating, she blew cold air onto my penis from her mouth. The same thing happened on.
If it's in your mouth like you're playing an oboe? Or as if you're blowing on a forkful of hot food to cool it off? Either way, not much. Although the latter one might.
Well that definitely is different. I guess it could be dangerous. I've heard that if you blow into a woman's vagina during oral you could give her air bubbles in her.
