s Ok so I'm looking for a story, well two stories technically. And I think i know the name of the series, Chemistry and one of the stories I think is called Stoichiometry. However, I for the life of me cannot remember the author or find a link to it. The first story starts with Xander and Buffy sleeping together until Buffy gets a boyfriend named Austin who looks like Angel. The second story involves Xander being turned into a demon by a potion accident of Willow's. I thought I had these stories bookmarked, but apparently I didn't and i cant find them at Spander Files either so a link would be most helpful.
