Could it also be The Perfect Mate by Beloved Stranger?

RATED MA

The first part of what you describe sounds like "Vying for Dominance" by ShadowsWeaver1. You can find it here: http://www.dokuga.com/spark/story/6918/1. This story is rated VERY MA, NO YIMs!!

Not sure if the rest of your description goes along with the rest of that story, but the beginning is very definitely this one!

Enjoy!

Hello Everyone!

I have literally been looking for this fic for years. It is a fic that I think starts with Kagome accidently walking through a barrier when she senses something. This barrier puts her smack dab in the middle of a fight between two female yokai for the right to mate with Sesshomaru (she doesn't know that at this time). Kagome wins and ends up going back to Sesshomaru's castle with him. Now this first half, I am not sure if it goes with the story, but I also want to find this one if it is not the same story.

While at the castle Kagome is attacked by a concubine of Sesshomaru's that thinks she will be the one to marry Sesshomaru. I think she was a red headed vixen or kitsune. She was actually servicing a lot of the quest and people for Sesshomaru and she somehow thought that meant he really valued and like her so he would marry her. After attacking Kagome, Sesshomaru kicks her out to be a gift for another kingdom. She eventually ends up in a brothel.

This story was very much rated M or above because it had a lot of spicy scenes. I really hope someone can help me find this story or its name.
