Fic rec: "Improbable Games" Humour and smut, all in one!
In "
Improbable Games", Sophie Richard has managed an unlikely scenario indeed--Snape agreeing to act out Harry's fantasies about Sirius. Part of what I love is the sheer love and communication that requires; although I generally don't care so much for "established relationship" stories, this one is wonderful because of all that Harry's request implies.
Oh, yes-- and the terribly snarky smut probably also contributes. :D
