The Asp at My Chest

Serpent friend of mine, your venom sweet as wine
Still I don’t believe you
Possess my hopes and then, don’t know what came of them
Still I just don’t leave you
Perhaps the fault is mine, and this the final time
You set yourself upon me
The fall will not be far, can still see what we were
And won’t be anymore
When the venom comes I’ll shut my eyes
As my body numbs and life unties
I will feel your pull one last time
Then will I escape you?
