I remember this fic had to do with Sesshoumaru's beast claiming Kagome, but Sesshoumaru doesn't understand it. I remember a couple of things very well.

1. His beast comes out and Kagome isn't sure how to deal with him. He says that if she kisses him, he will let Sesshoumaru come back out.

2. IIRC, Inuyasha tries to rape Kagome, and Sesshoumaru rescues her. He tends to her wounds in a small hut I think by licking them.

Definitely not one for the kiddies.

When he says he will let Sesshoumaru back out for a kiss, weren't they in a cave and she woke up wondering why Sesshoumaru was holding her? And I think the only way she could tell that she was dealing with his beast instead of him was by seeing if his eyes were red.
I'm pretty sure this is still a work in progress. Though I'll be darned if I can remember the name.

Yeah, I remember that as well.
