So I'm thinking Buffy is a Jedi fresh out of the Temple (prequel era) and Faith is a Twi'lek ex-Jedi who now smuggles shit on a Hutt world. They team up when Buffy stumbles across a Sith conspiracy. Sex scenes involve gratuitous lekku fondling, because a Star Wars AU isn't living up to its full potential if someone's lekku aren't getting fondled.
