What's your favorite story-focused porn feature?
You can combine the prettiest faces with the hardest bodies and the most mammoth of dicks, but without a good plot, I'm likely to start fast-forwarding the scene about three minutes in. A good story (or even a pathetic, hackneyed plot) makes the sex so much more intense--so much hotter.
This was especially true for Out of Athens, The Crush, and Buckleroos (where many of the guys even repulsed me). If only those Bel Ami models could speak English!
