Blackmail surrogacy

BLACKMAIL SURROGACY
Four million will be enough
Since the task is really tough;
I'll pay unless you agree
No effort will go for free

No amount persuasion will allure me
No amount of money will convince me ;
But we had a consensus that you signed
And I never want you to be detained

Then take anything that pertains you
My offspring won't be sold like an ewe;
I know you'll loose the gusts once jailed
And your plans will have failed

I'll be firm unless you divide him laterally
And the corpse will be shared mutually ;
We partition it and you breath your last
Or else you adhere to what we agreed first.
