Fanfiction 1:
I believe I found it fanfiction.net but I could be wrong. The story is Cannon Universe and starts off with Sesshoumaru killing Kagome but she comes back to life, it becomes a game where Sessh comes kills Kagome and she comes back to life right away.
I recall at one point he kills her and she does not come back to life right away, I think he uses Tensaiga and brings her back she is panicked because she knew she died and he is upset that she did not return to life immediately.
I know they do end up together at the end but this is the extent of what I remember of this fanfic.
Fanfiction 2:
This one I recall reading it on Adultfanficion and I think A single Spark. It was a 3 or 2 chapter story and also Cannon Universe. The premiss is for some reason Kagome is living with Sessh and he gets hurt I believe and she uses modern day pain killer to knock him out to help I believe and what actually occurs is due to the chemical reaction in a demon his beast comes out and well has sex with Kagome impregnates her. She carries the child, who is a girl, to term and during this time and after her and Sesshoumaru do not speak because I believe he blames her and she finds it stupid but since both stubron they do not work out it. I believe their child is 5 and they finally decide to talk to each other, I think it is after Kagome hears a conversation between Sessh and their daughter that she initiates conversation and they mend things up.
I would greatly appreciate any help with this!
