Out of the three, Monica, Phoebe and Rachel, one should kidnap the other two for an afternoon - maybe the other has stlen a dress or something?
But which one would be the domme? Obviously Rachel would be the most submissive (maybe she could turn the tables in the end?), so it would be between Monica and Phoebe to fight for top dog.
Don't want any major multi chapter epic, can just be a few simple ideas and i'll let my imagination do the rest

Best story idea wins a prize (that ties into the story theme but i don't want to give any secrets away) if they give me their email address at the end.
