I really enjoyed this one fiction... now I can't remember the name.
Kagome encounters Sess in heat. He takes her, impregnates her, she runs off with Shippo, lives and trains with a demon, a minor Lord takes her and marries her by force, she looses the baby, somewhere in all this she is forced to train with some warrior monks who are protecting a god that comes to earth, he lives blind and only speaks in people's head, he's the one that insisted Kag be trained with the warrior monks to prepare for the final battle with Naraku. After her training, she gets a dot on her forehead.
I know that the description really bounces all over the place, but I was just typing as I was remembering parts of the story that I thought could help locate it.
I hope you can help... it's driving me a bit nuts.
