Eternal Triangle | nosirrah

I can see no reason why
The three of us, you two and I
Cannot live in perfect harmony
We could live a perfect life
One of you could be my wife
I.e. take my name if you agree
And I see no reason for distress
If the other becomes my mistress

There would be no favours shown
Both of you I'd call my own
Although I cannot do it legally
But any children that you bear
Would profit from two mother's care
And share my name and fortune equally
I cannot see why the family unit
Should only have two parents in it

The advantages would be immense
Quite enough to recompense
For any drawbacks most successfully
For one we'd never have recourse
To institute a divorce
You could just change positionally
So neither one of you should feel despondent
At the thought of being named a correspondent

Think too of our peace of mind
Never having cause to find
Companionship and love illicitly
No accusations or confessions
Of extra-marital digressions
We could keep it in the family
Though I also make the supposition
You'd  find stimulus in friendly opposition

There is nothing wrong with it
In some places it's quite fit
And practiced by all religiously
Which will help in explanations
With your respective relations
Who may view the match distastefully
Wait a minute - I've just seen the flaw
Forget it! I'd have two mothers-in-law
