Dumb or smart, it's all good, as long as it's clear that the girl is in over her head, but soldiers on like a good whore. When you manage to capture those wonderful reactions, it's porn gold.

As uneven as the "Gag Factor" and "American Bukkake" series are, you occasionally get these scenes where the girl just had NO idea what she was in for. It's almost worth watching every release in both series to see this kind of scene.

Not that I don't enjoy seeing a girl go in the other direction, and revel in her own degradation - e.g. the Kylee King scene in GF20 where she laughs as she blow spit bubbles from her nose! I love that shit too.
