Treasure hunting

[mysid]

Please help me find a fic. At some point in the last few days, I read a fic in which: Remus, full of unrequited longing for Sirius is caught--by Sirius--watching him get dressed. Sirius is on his way to a double date (James, Lily, and a girl named Winnie Chan) and so leaves without saying anything. Remus has several hours to drive himself mad with worry before Sirius returns and confesses that he fancies Remus as well.

I can't remember the title, the author, or the site where I read it. I can remember the name of the beard but not the author; I'm pitiful. Help me?
