I'm trying to find a story, and I'm hoping someone here remembers the title. It's about a pair of identical twin sisters: one makes a wish on a fortune cookie for her twin to gain weight, and once she's around 300 pounds the she makes a wish that they'd be identical again (only it backfires and the first twin finds herself gorging herself and magically fattening up, too). I want to say it was unfinished but in 6 parts. Does anyone know the name of the story or the author?
