Original sins

There’s a  fortunate fellow called Binns,
Who made love to identical twins,
So alike to each other
That even their mother
Just scratches her head, shrugs and grins.

It began, as it often begins,
With champagne and a couple of gins:
Inhibitions were shed,
And they jumped into bed,
In a tangle of tits, teeth and shins.

They exhibited bumps, grinds and spins.
They had semen from fannies to chins!
It was jolly confusing,
But later amusing,
Confessing at church to such sins!
