A Partial answer (not quite the same in every way to the story requested!!!) to DDM's Challenge: Constant In Every Universe.... This story is definitely inspired by some of the points-the details- of that request, yet I've changed some stuff/ignored a fraction of it.
An AU or Abrams-verse or Abrams-verse AU, in which: Jim details a previous mission that led to them meeting Edith Keeler, for a second time, even though he had to watch her get killed (the first time they met).
They meet Edith for a third time, now living on New Vulcan, and working to help the Vulcans.
Spock's Pon Farr is (not purposely) brought forward.
Jim and he do the T'hy'la, in love for FOREVER, thing!!! (Incredible love; Incredible sex!!)
