I desperately need help finding a story. Please help me! The story is rated M and is a Sesshomaru/Kagome pairing. This is what I can remember of the story:
Kagome returns to the Feudal Era and saves Inuyasha, Shippo, and a bunch of other prisoners from a dungeon. One of the prisoners, a young demon, is badly injured. In order to save him, Kagome channels her healing powers through the young demon's father. All of the prisoners escape and return to Sesshomaru's castle.
Kagome is reunited with all her old friends. Eventually, Kagome has a fight with an ox (or bear) demon that doesn't like her. Kagome defeats the demon and makes him her personal companion, making him follow her everywhere. An evil is brewing and several events occur as a result of this threat.
A female demon desires for Sesshomaru to mate her and in a fight releases a lust potion. Sesshomaru succumbs to the potion and must be confined to a cave. Kagome willing sacrifices herself to save Sesshomaru. She barely lives and makes a slow recovery. Finally, Sesshomaru and Kagome acknowledge their feelings for one another. The evil that has been threatening the lands arrives at the Western castle, and the reader finds out that the evil is actually Kagome's grandfather (or something like that). The battle between good and evil is about to begin.
I implore you to help me find this story; I have been looking for it for months. Thank you for any assistance that you can give me.
