Looking for Teen Wolf fic

I'm trying to find a fic where Peter seduces Stiles when Stiles is still in high school and they have a fucked up relationship in that they both kidnap each other, tie each other to beds, and then leave for hours. Finally they both have enough of this and start to have hot, dirty, wrong sex, at which point the story ends.

The next story takes place five years in the future and Peter has died and it's about Stile's grief and coming to terms with Peter not being in his life anymore.

For the life of me I cannot find this story! :(

I was hoping someone on my flist has read it and is willing to point me in the right direction.

I'd appreciate any and all help!

EDIT: Story Found!
