Swan Queen AU: wherein a very damaged Regina and meets a very vulnerable Emma long before her 28th birthday, and they have ongoing sexual hook-ups throughout the years, both of them completely unaware that Regina has adopted Emma's son... until Henry brings Emma to Storybrooke, and they begin to realize that maybe meaningless sex wasn't as meaningless as they once thought.

What if Regina adopted a five year old Emma, never knowing the truth about the little girl who became her daughter? What if Emma and Regina lived together happily as mother and daughter for many years? And what would happen when Emma inevitably found out the truth about her adoptive mother?
