Okay I do not remember the plot all that much but I do remember a few things here and there.
It was a canon based story.
What I remember the most is there was a part in the story that Kagome was traveling (for what purpose not sure) she was escorted by soldiers of the West or something of the sorts.
I think the caravan was attacked (hazy on what happened) and somehow Sesshoumaru shows up in the forest that the attack happened.
I remember almost distinct dialogue of when Sesshoumaru was engaging in sex with Kagome in the forest and was going to begin anal sex for the first time with her. She said something like "no dirty" but did it anyway and enjoyed it.

I really would like to read the whole story again. I remember it had a compelling plot line as well as nicely written lemons.
It was on A Single Spark, that is where I read it.

Thanks for your time!

Huh, you know this one vaguely rings a bell...but I can't remember! If you figure it out could you please give me a holler? This one's gonna bug me now lol
