Not a rec, but you know I wrote a big ol' long parselsmut thing a year ago? in bits and pieces. In my memories. It's quite ridiculous; basically, anyone who hears Harry go off hissing goes instantly glassy-eyed screw-everything-else horny. Much with orgies, basically. I do not claim it is high art, BTW. Just porn.

:D

I didn't ever hear the term parselsmut before that, so it's possible marks and I invented it chatting about the thing, but I have no definitive data there.
