Enveloped in Python

My pet, my pet-how fun you are
I trust you so much I even leave the cage door ajar
You'd never harm me, but just to be safe-I admire you from afar

The coiling is fast
This time it's your last
Your soul asphyxiated
Final chance for escape terminated

Enveloped in python
Constriction complete

So harmless-me the master-you the slave
I reach out to touch you-I'm getting so brave
You affect me but little-I still haven't changed
And to those who find me abrasive-it's you that's deranged

The coiling is fast
This time it's your last
Your soul asphyxiated
Final chance for escape terminated

Enveloped in python
Constriction complete

Where dreams become nightmares
Of total defeat

Not just a white line or addiction of some kind
But entanglement with anger or to bitterness bind
