So I just got done reading a really good 3P romance fic for Mai Hime (Monsoon by Sombereyes, thanks for asking), but I've run into a bit of a problem at the end. That is, now that I've read such a great bit of ShizNatMai, I want more polyamorous lesbian romance. The problem is, there really isn't any to speak of.
So I'm looking for recommendations. Tag searching at AO3 and FF.net turns out to be a pretty futile endeavour, and often seems to involve some pretty extreme porn. Not the most efficient way to find stuff. I did find this page but you'll note how few entries there are.
I'm interested in fic, but it doesn't have to be fanfic. Short stories, original fic, published novels, all are fair game.
