There are lots of Bella/Edward stories on www.adultfanfiction.net. I really like “Polar Night” by belladonnacullen. I also enjoyed “La Tue Cantante” by Shigure-san although it isn’t straight a honeymoon story. I loved reading “Just a Tasteful Little Affair” by LadyExcalibur however she stoped after only a few chapters and I have no idea if she is planning to add more chapters. My favorite Bella/Edward honeymoon story is “Missing Dawn” by KariAnn at www.kariann1222.livejournal.com. She also has a terrific Jacob/Reneesme story called “In Pursuit of Normalicy”. I didn’t think I would like it but found it to be terrific. KariAnn is a great writer so everything she has posted is fun to read. I was team Edward all the way but in the story with Reneesme I find that I also like Jacob. Hopefully this gives you some ideas where to start. Enjoy, there is a lot of fanfiction out there with Twilight characters, some good some bad.
