More for my use than anyone elses, but feel free to click the links if you want Battlestar smut.
Lee and Kara, Kara and Lee by Mnemosyne
Lee/Kara
At least ten pages of pure smut, with a pinch angst thrown in for bite and even a handful of plot for flavor. The best kinda recipe there is. ;)
Twelve by Rheanna. Lotsa plot. Not so much smut, but still a very good read. Also, is long and novely, which is just the way I like it.
ETA October 2009
The link for Twelve is broken. Lee and Kara still works, though.
July 2012 - as luck would have it, by pure chance when I was perusing through some rec sites looking for fresh stories, I ran across another link for Twelve. Hurrah!
