Loved the way this started out, with the "Who is it?" discussion, followed by such a passionate display of ownership and their need to be owned by each other. An excellent ending!
I've looked forward to every chapter of this story - it was always intensely emotional, dramatic (but not overly), with a wonderful (and In-Character!) progression of their relationship to something that they can't live without. I don't know how I'll live without it either =) Thank goodness you've talked about a sequel.
