I've mostly seen it as those stories including more sexual aspects, but that's mainly because...well...that's how it usually is.
Maybe we could leave the n-fic folder for that, and create a mature audience folder for those stories that are more than PG-13, but not "naughty". That way those that aren't registered in the nfic section because they don't want to read the "naughty" fics, can still see and read the fics that are more than PG-13 for some other reason.
