This is a Sess/Kag story, set in modern times. Where Sess goes to meet Kagura in the ladies room but she's going on about how she doesn't like that Sess gets 'fuzzy' when they do it, and he hears them. However, as he's sitting in the bathroom 'mope-ing' ('cause this Sesshoumaru does not mope...') Kagome comes in and then somehow they end up doing the dirty... and he goes 'fuzzy' and she loves it...
I haven't read this story in forever, and I know it's not '
Sesshoumaru's Fuzzy Problem' by Speedy Tomato...
So if anyone can help me out that would be fantaboulous!
