There was a story that i don't remember but it this is what i remember.

It was set in the modern era and Kagome is the part of Inuyasha's pack taking care of finances and other things. She finds out that Inuyasha is cheating with Sango so she decides to leave. After talking to Sesshomaru about it he takes her into his pack with his two other brothers and his sons. Eventually Inuyasha's pack is falling apart without Kagome and demands her back but Sesshomaru already mated her so he pretty much gets his butt kicked.

Thats about all i remember

Please Help Me.

Wow, this looks interesting. I'll see if I can find it for you.

Sounds like you're looking for Pack Dynamics by sesshou_lover. Rated MA. Part two is in the next chapter. Enjoy!

I know this one but I can't think of the name. It's one that has been looked for before and I think it's part of a collection.
Edit: Nicole posted the right one

I knew that I had heard of it! I've read that a bunch of times.

Oh... Nicole has answered it. I love the story... and would love to strangle Inuyasha and Sango at that. Even Naraku and Kikyou are much better than them

Yes thank you so much. This is definitely the one. THANK YOU THANK YOU THANK YOU NICOLE.

You're welcome! This is one of my favourite collections

Is it chapter 12 of trapped by sesshou_lover?

EDIT BY WICCAN: This story is rated MA, NO YIMs!

Nope. Pack Dynamics is chapters 10 and 11. Chapter 12 is All My Children - Kagome finds Sesshomaru's youngest pup at the park and becomes their new caregiver.
