I have a fart-in-my-mouth fetish, iin?

I love having women (usually prostitutes) fart in my mouth and letting the fart permeate through my sinuses and into my lungs. It is very hard to find someone willing to do this, who can actually deliver. Most prostitutes I've paid to do this weren't able to let out more than a squeak, or a little brown stuff, but still took my $50.
