Masques, I believe. I may have written stories longer or as long for other fandoms, previously, but it's hard to tell because they were pre-internet and published in paper zines, so I have no k count for them.
I wrote the second half of it 'live' - as soon as I posted one part here on the mbs, I'd be writing the next and sending it off to my beta to get it ready for posting within a couple of days, often incorporating ideas brought up by readers as I went, which would sometimes double the page count.
I'd never written like that before - and as the Queen of the Rewrites who normally has to go over the same paragraph 20 times until it is just right before I can move on to the next, it was the most exhilarating and frightening thing I've ever done.
Scary, but ultimately wonderful.
