Oh goodness, those are everywhere, not hard to find at all!
But I'll share a few of my favorites.
Insanity is Hereditary By Danyealle-sama, Rated MA
In yet another effort to get Tetsusaiga, Sesshomaru plans to hold Kagome hostage after coming across her while she’s alone. However, Mother Nature has other plans for the daiyoukai, ending up putting him in debt to the miko, much to his chagrin. From that twist of fate comes a very interesting ride for both of them that leads to an ending neither could have ever predicted.
Beyond Broken By Knight of Disorder, Rated MA
Six years since she first fell down the well, five since she wished Kikyou back to life. She craves touch and intimacy, she craves to hear her name on the lips of a man.
Seven Feudal Fairy Tales By ladybattousai, Rated MA
After reading a poetry scroll amongst the relics once belonging to Inuyasha's mother, Kagome traps herself and Sesshoumaru in another world, where they must journey through seven, different fairy tales and complete the poem if they wish to return home.
About this one... I can't remember if too much of the story takes place outside of the Fairy tales, but they are still their roles as you know them, Miko and Lord.
And I just read a story that was beyond amazing that I can't for the life of me remember the name or author of...
Maybe someone else will know it.
Kagome is returning from her era to the feudal era when something goes wrong with the well. It takes her back in time, but much farther than her usual Five Hundred years. When she climbs out of the well she meets a young boy who is nothing like she expects.
I just feel horrible that I can't remember.. But anyway, the others are really great stories. I hope I was helpful, and if I think of more I will be sure to let you know.
