Porn Without Plot

"Jesus: This film is very low-quality. There's no story. Buck: It's a fuck movie. I don't watch a fuck movie for the story. I watch a fuck movie to see fuckin'."

- From Dusk till Dawn 2: Texas Blood Money

As "PWP", a shorthand flag for stories whose sole purpose is to present a sexually-explicit situation (very often not very well-written); "stroke story" is another term for the same, especially in erotica. A PWP is almost always a short story, as going more than a few scenes runs the risk of accidentally discovering a plot which may well take over the story and shove the explicit sexual content off to the side. However there exist many multichapter PWP fanfics written with the intention of cramming as many explicit sex scenes in as possible.

PWPs are convenient for the writer who wants to produce smut, because they do not require justification, they simply happen with no explanation. PWP can also stand for "Person With Person", because of the frequent occurrence of... non-standard couplings, similarly without the need for justification.

Although classified here under Fanfic, PWP is by no means limited to fan fiction.

Unless you know of any Egregious examples and can keep the detail to a minimum, please stick to listing in-universe examples or references only.

Anime and Manga

 * Interestingly, this is where the word 'yaoi' comes from. It was originally used to refer to plotless gay erotica, and was an abbreviation of 'yama nashi, ochi nashi, imi nashi' (no plot, no point, no meaning), and rapidly spread in usage from there. Male/male romance in general is more properly referred to as the Boys Love Genre, for reasons that should be obvious.

Live-Action TV

 * Drew Carey lampshades this in one episode of Whose Line Is It Anyway?, comparing points to the plot in a porno.

Web Comics
"Rick: Porno could be so much more in the right hands... but it's mainly just, "Whoops, wrong door! Let's fuck!" Drew: How about we make our own porn? Want to lick this spoon clean, or lick it off of me? Rick: So, this would be a porn where I'm picking body hair out of my teeth for a half-hour? Yeah, there's a plot."
 * The webcomic Blur the Lines converses about this trope before moving into an in-universe discussion.
