Fic Rec: How The Dead Celebrate Birthdays (PG-13; Severus, Sirius & Remus) by eeyore9990
I'm not certain if anyone's read this before, or even rec'd it, but I have and am!
Rating: PG-13 Warning(s): Canon characters who are dead through no fault of mine (or theirs, for that matter). Also, disembodied mammaries and clowns. Eventual threesome. Word Count: +/- 1700 Summary: Severus has a very firm opinion on the dead celebrating birthdays: They don't.
Why you should read it: It's great fun! Severus' is a snarky bastard, oblivious to what's going on for quite a while, but Sirius and Remus wear him down...with something very, very sweet.
