Violent eyes, violent mind

Warning: Graphic depictions of violence towards others

I lay my eyes on you, and my inner beast awakens. 
Gently it rises, stretching and wrapping itself around me like a second skin.
There, it purrs into my ear. Isn't that a nice target? 

As you talk, it sinks its fangs into my adrenal glands,
releasing epinephrine into my blood system, making my fingers shake
and sharpening my thoughts into silver-glittering blades.

Go for it, it growls. Shut them up and break their arrogance.
Apply fist to face, shattering their ugly glasses directly into their eye sockets.
Let them feel their mistake of disrespecting you.

Ram the shards home with my own forehead,
sending them to the ground whilst revelling in the fresh pain of cuts
getting them acquainted with the sole of my boot.

It sings stories of violence to me whilst you yap
and I am beginning to enjoy it, finding it harder to withstand
agreeing more and more with its assessment.

Finally, a particular image comes to mind:
you begging for mercy through broken teeth, swallowing blood
and me granting it by marking you.

Your ears. They're mine now. One will be cut
by slowly pushing my blade crosswise through the cartilage 
whilst feeling the saliva pooling in my throat.

Finally, the beast will be sated by biting off the other
rejoicing in the carnal pleasure of cutting through it with my teeth
howling my triumph and rage into your ruined face.

I chain the beast before it can act.
I lock it again into my depths, ignoring its screams and pleas
leaving it where it is under control.

I leave you with my face calm
my fingers still, my voice low and my words clear
but my heart still racing.

And deep in its cage, the beast looks up at me
and grins with teeth full of sadism and whiskers washed by blood
Just you wait, it says. My time will come.

One day, you will let me loose.
And you will enjoy the carnage more than me.
For I am you. And you are me.
