Handjob vids (a.k.a. “overpaid babes phoning it in”) are hardly a major sub-genre that deliver a steady cash flow. Here's an example of why. The excitement factor never peaks; even when cheating is involved. To all but the most devoted tug fan, each segment looks like a tepid appetizer for a meal that never arrives. Even Trina Michaels (who could make the statue of Lenin cum) doesn't deliver a volcanic jerk job.
The cheating aspect occurs when the girls rub their beef curtains on upraised cock and also suck off the dudes. In fact there's so much oral action that the vid could be retitled Fantasy Blowjobs and it might perform better. Are we expecting too much, or is a clean jerk simply boring because it's the nature of the beast? We'll get back to you.
