Shoujoai ni Bouken: Adventures of Yuriko
A series I ran into a couple years ago (and forgot all about until now) -- I'm not sure how to classify it. The folks who host the site it is on call this kind of story Yuri. Not something I would typically read. (Mainly because I'm not the kind of audience it is aimed at so I don't run into this kind of story very often where I 'hang out'.) If it were fan fiction it would be called femslash (which I do read, as anyone who comes here should know by now.) -- though this story barely deserves a PG-13 rating.
It isn't fan fiction but has the same sort of breezy, light style a lot of fan fiction does.
This particular story is set in Japan - the main character is an "idol" - a Japanese specific celebrity type (They sing, they dance, they act - like Madonna or Britney Spears with a shorter shelf life?) who happens to be a lesbian. The story covers her romantic/work life over the course of several months while she works on a "Reality TV" style television show set in a Japanese high school.
(If you aren't into Japanese pop culture, lesbian characters, or romance... you might want to skip this. It isn't short. There are over 90 parts in the first story. And the second story is currently 42 parts long...)
