Twisted Knife

(Found this that I started ages ago so thought I'd finish it)

The knife punctures through
A heart that was pure and true
It stabs right in there
Piercing without a care

Then someone comes along
With a grip so strong
They twist with all their might
A tortured soul is in their sight

Weakness consumes
The fight is over they presume
One strong wrench
A heart left on the bench

But what is really left
When escaped is the last breath
A successful murderess
A desperate man wanting any caress

A body with no heart
As two others tore it apart
