Choose your poison

From my collection I call the Chronicles of "him".

I want to be your poison
I want to be your disease
Your addiction, your drug
the one thing you'll always need

I want to choke you and take your breath
Turn your lips a cool shade of blue
I want to be your poison
I want to be the death of you

So choose your poison, choose it well
please pick me to do you in
Your drug, your obsession
I can be your deadly sin
