Dogging. (A bit ruff)

Fornicaters unconcealed
Ignoble in their carnal lust
To wanton yearning , willing yield
In pastures green they writhe and thrust!
 
Voyeurisms gift to you
Whomsoever, wants to view
Daytime fayre or woods at night
All laid bare, in pale moonlight

But soft, what beams
afore me there
the law in teams
PERVERTS BEWARE!

though not illegal
to some it's odd.
But you're all nicked
Says P C plod

Now stop with the sex
Pull up your kex
By these rubber necks
You've been fingered

The tools have nothing more to do
Than hold their nuts and watch you screw
The fools all disappeared from view
But the shrewd and cunning lingered
