I read one a few months back and for some reason did not add it to my favorites. I do not remember everything about it, but I do remember it starts off with Kagome being severely depressed. her mother calls Sesshomaru to come over and Kagome winds up asking him if she can be more than just pack. He agrees and it gets very descriptive and mature in content and then she winds up facing challengers for the right to mate with Sesshomaru. During the mating there are four new youkai souls created. Please help as I would really love to read this one again.
