They like the way you bleed,
They like the way you scream.
It's a service to you and them,
It's a service that they need.  
You are a device.
You are a tool.
A Swiss army knife of pleasure.
Even if it costs you an arm.
Sharing is caring you know,
We share my blood in an oath.
Sister and I by blood,
Is this ******?
Will I ever get enough?
I have scratches,
I have scars,
I got bite marks all over my arm.
Takin blood,
Takin pain.
Because darling I love your eyes when your insane.  
We are the true animals,
We both come alive as we sense blood.
Your sharp blades and euphoria,
Are what really tie me to the ground.

And I smile the whole time,
Knowing that,
My pain is your pleasure.
Then I fade away.

Only to stop you at your discretion.
