"Plot What Plot?" Stories necessarily have plot, the series of causal relationships connecting what happened before and after. So to get technical, PWP would be a narrative.

Don't get me wrong, there's nothing wrong with narratives. It's irritating, though, when an author tries to pass off porn-in-text as a story. When fiction only serves to titillate, it no longer cares who the characters are or what motivates them.

To quote Forrest Gump, "And that's all I have to say about that."
