Established Threesome

[gwenhvier.livejournal.com]

I've read a lot of PWP fics that have threesomes, but I would like to read fics with actual plots that have an established relationship of three people, or the build up of the relationship. A requirement is that the fic ends with all three people still together and everyone happy. I'd prefer it if it were slash and that John and/or Rodney be one of the people in the threesome, but I'll really take any combination of people. Thank you.
