Okay, guys. This question I have goes out to all of you 'facesittng experts'.
It's pretty simple: What's the best way to endure a facesitting?
I mean, we all know the videos (especially those brazilian ones), where the woman sits on the victim's face for like 10 minutes without giving the poor dude a break.
Personally I cannot endure that longer than 30 seconds or so. So what's the best...'technique'? Is it better to hold your breath completely, when the woman engulfs your face in her pussy or do you try to still breathe through it somehow?
I want to know that, because I plan on having one of those brazlian-type face fuck sessions with a local escort myself here and it's not that much fun, when she has to give breaks every few seconds.

Any tips you could give me?
