I quite probably recommended it to you :-p

No, I didn't find it on phanwank. I found it in my favourites, though I had no recollection of reading it before; I imagine I originally came across it when I was trying to track down a Carlotta-fic I vaguely remembered (and which eventually turned out not to be tagged for the character at all, possibly for good reason: https://www.fanfiction.net/r/2744161/ )
