Im looking for an AU or a Cannon fic (not too sure)...all that I can remember is that Kagome wakes up after making her wish on the complete Shikon to an entirely new future. Along with learning that she is the purest female in existance, she becomes Inuyasha and Sesshoumaru's mate. The specific scene that I remember is after a night of sleeping in Sesshoumaru's bed, she asks him to get her the same mattress...little does she know, its made out of Sesshoumaru's fur.
If you could help me find this fanfic, I would love you forever its one of my all-time favorites. Thank you.
