The pic I'm looking for in particular is an FMA/HP crossover where Ed is looking into the mirror of Erised and seeing himself screwing Al. Ed is blushing, and Al is asking him what he sees.
If someone could give me a link to this pic, I'd really apreciate it. I liked it when I first saw it, and I tried to fav it, but my stupid computer wouldn't let me log in. I haven't been able to find it since.
