Scooby gang under the "Spin the Bottle" spell

[moscow-watcher.livejournal.com]

Copy-pasting Drizzlydaze's inquiry from BuffyBoards:

Does anyone know a fic which has the whole Scooby gang under the "Spin the Bottle" spell from Angel? Like a Spin the Bottle version of Tabula Rasa. Spuffy.

I vaguely remember that story -- I remember that Anya starts to speak Swedish and Spike turns into William, while Dawn is the only person inaffected by the spell. But I can't remember neither the title nor the author.

Thanks in advance!
