I think "storyline" porn is largely a thing of the past. Sure, some porn scenes still have a theme or setting (although many don't), they don't have the old dramatic scenarios of the VHS tape porn I saw when I was much younger. With most porn being accessed via download now, people just want and get the sex, no time or patience for anything else. The technology is just following our tastes. I generally fast forwarded through "drama" anyways. Sometimes I do miss the buildup, though. All payoff makes it more intense and less rewarding at the same time.
