You wanted to be her cocaine

Weren't you the king of lust reign?
You always said: 'no pain, no gain!'
The man without any restrain
You wanted to be her cocaine
But you've been a stroke in her brain
Like poison injected into a vein
Now she has to break the chain
To step away from the pain
To shelter from the rain
She just needs to strain
To go to take a different train
Now she knows has loved you in vain.
