2metaldog wrote me a gift fic as part of the same Secret Santa exchange... and she gave me her two original characters in what is technically a Ai no Kusabi fanfic, but she's written it so well, you don't have to know the source to enjoy the story. I just fell in love with her characters.
It's called By the Waters and comes with its own sound track as well. I really enjoyed it, it's very sweet and mildly R-rated yaoi. *grins*
I really loved it. *happy sigh*
