Oh god! I have many! 

Ahuacatl by Occasionalcoffeethereturn has one of the hottest sex scene I’ve ever read. It stayed in my mind for days after I read it, and I still think about it sometimes, either I want it or not… 😀

Black Nail Polish by SJ (actually everything written by SJ) is also one of my favorite, for the same reasons as the above. 

If you want something longer, I suggest In The Beginning which tells the first meet up between David and Gillian and how everything started, and it’s exactly how it happened in my head. Sadly, but I also love London A.X.

Hope you love them (and haven’t read them all already!)
