Glee Finders

I'm looking for a Kurtbastian fic. Kurt's at Dalton with Blaine and Sebastian. he has what he thinks is a mostly physical relationship with Sebastian because "Sebastian doesn't do feelings." at some point his teacher gets mad at him for some reason and makes him drink or otherwise ingest some unknown substance. This either turns him into a girl completely, or it gives him breasts. Kurt freaks out, Blaine sees him, and they try to stop other people from finding out while at the same time finding a cure. Blaine tries to get Kurt to tell Sebastian because he thinks he'll be fine with it, and also because he doesn't want Sebastian to think that Kurt is cheating with Blaine, due to the extra time spent together trying to find a cure and unfortunately misleading situations seen by others. At some point i think Santana, Kurt, and one other female (Brittany? Rachel? idk) either seduce their way or break in to the back part of the jail, where they're holding the teacher, to find out how to fix Kurt. i can't remember what the teacher says. meanwhile, Kurt feels he needs to distance himself from Sebastian in order to stop him from finding out and/or stop him from breaking up with him (because in Kurt's mind it's as simple as Sebastian is gay and Kurt's cismale anymore). there's a scene where Sebastian is trying to find out what's wrong, clearly he cares about Kurt but doesn't know how to/doesn't want to show it well. Kurt is missing Sebastian and about to tell him. Sebastian thinks Kurt must have gained weight and is self-conscious about it, so he makes some offhand comment about his body, and it strengthens Kurt's belief that Sebastian can't know. instead he breaks up with Sebastian, hoping that he can figure this whole thing out quickly and get back together with him before it's a huge issue (just say the break up was a misunderstanding or an in the moment cruelty that he didn't mean).

It's a WIP, or at least it was when I last read it, and hadn't been updated in a while. I think it was on LJ, if that helps anyone. Thank you so much for your help and I hope someone remembers what fic it is!

Hello,

I'm looking for a prompt that (to my knowledge) was never filled. I remember that the tags on pinboard are wrong, and so it always took me forever to find it, and then I never bothered to contact one of the GKM mods to let them know about the error. And this time I can't find it at all, so shame on me. What I remember is under a cut, for trigger purposes.
