Ok so this fic is WAAAAYYYYYY old and I think I first read it on FF.net...

It starts out...I think...Kagome and the son she had with Sess (at some point in time) are running from an enemy that wants to kill her and the kid. She goes to Sesshomaru for help (although he's the last one she wants to run to) and he's not terribly happy to see her. I think the last chapter ends with her giving him a back massage in the hot springs!?

I don't know if anyone might know of this fic, it's SEVERAL years old, but any help would be much appreciated!
