I don't remember the name of this story or what it's rated. I think I first read it on ff.net, and it was a complete story. I just read "Atonement" by: Miss Kagura and that story reminds me of it a great deal.

I remember Sesshomaru and Kagome building a relationship throughout the story. I don't remember how they ended up in each other's company, but I want to say it was a result of a betrayal. Either Inuyasha betraying Kagome to be with Kikyou or Kikyou betraying Inuyasha to get Kagome away from Inuyasha. There's a chance that Kikyou tried to kill Kagome.
I remember that there was some kind of destiny/prophecy going on where Sesshomaru and Kagome were supposed to be together and Inuyasha and Kikyou were supposed to be together. Somehow, somewhere near the middle to end of the story, Kikyou was brought back to life.
I remember Sesshomaru bringing Kagome to a place that was really nice and there was no one else there.
I also remember that Sesshomaru and Inuyasha were to rule over Japan, possibly creating a different future, a better one than what Kagome came from. Might be a part of that destiny deal.

I hope someone remembers this, because it's driving me crazy not to remember.

Could it be Children of the Gods? The story is rated MA so careful.

Unfortunately it's not Children of the Gods. Unless it's different from the one I have in my favorites. The one I have is by D4rkD4wn.

No it is the same story. Hmmmmm. perhaps it might be, To Taint A Pure Soul by TheFallenAngel its rated M

No. That's not it either.

I'll see if I can remember some more details and see if that helps.

I found it! After looking through someone's rediculously long favorites list on ff.net I managed to find it, and here it is.
