Daddy's Pet

I saw him first. I knew him first. I loved him first, but here he is being introduced to me as my new step-dad.

How could this happen? How could he end up married to my mother, the one person I can't possibly steal him from and yet...

Now that I'm no longer an eighteen year old child and he isn't my teacher, lines are beginning to cross.

What do I possibly do with this desire and guilt that keeps overlapping and why is it when I try my best to keep my distance he keeps pulling me in?

It feels so wrong and yet it feels so right, will I be able to ignore this longing or will I want him to hold me tight?
