Two fics that prove there's life in the old fandom yet:
The Slayer's Vampire Tryst by
snickfic, PG-13 Buffy/Spike. This is an absolute treat. Great Spike/Buffy character voices and wonderful humour from one of the best writers out there.
Wasteland, by
nomelon, R, Spike/Riley. This is just wonderful. Beautifully written and sexy as hell. And while you're about it, why not check out
nomelon's other Spike/Riley fics, particularly the utterly brilliant Domestic Bliss.
