Hey I don't remember much about it but here is the beginning.
It takes place in the feudal era and inuyasha and the group are convinced by kikyo( I think) that kagome is useless and they tie her up just before the fight with naraku. When naraku shows up he says that he raped kagome and sesshomaru later takes her in. Sesshomaru needs help with a broken kagome so he calls in some inus from Scotland or Ireland.
Hope someone knows this fic if you don't thank you for trying anyway!

Lucky you, as I was sorting through this one this week! You're looking for A Question About Honor by KogasAngel. It's rated MA/R, no YIMs!

Thank you so much Fye! This is just what I was looking for.
