I may have seen as much of this stuff as you, but you have no doubt written about it far more than me, and in a manner tantamount to obsession. So I find it odd that you didn't remark on the "Guh!... Guh!...Guh!" section. And inevitably this leads me to the conclusion that my fixation on these details is bizarre and perhaps unhealthy. I experienced this same thing after viewing the A. Snow GF5 scene for the first time. I read everything I could find on it and was astonished I found no mention of her sounds anywhere. I'm ashamed to say I may have gotten the ball rolling on it.
The AS quahs and the Georgian Belle GUHs are for me like the "I renounce Satan" sequence in 'The Godfather' or the Club Silencio scene in 'Mulholland Dr.' They are ground zero crystalizations of what the pornography is about, its meaning, its reason for being.
