Well let's start with general sites like FFN or even AO3. Hell, we even have some fics submitted in prior fanfic exchange programs Kirby already hosted. You can take a gander at the Rec list that's stickied and browse through stuff there that has what you're looking for. You can even go through the author tags for certain writers whose forte is yuri, like RadiantBeam- look I'm not gonna spoonfeed ya buddy.
