Trout fishing

Your line goes quite tight,
As they tug at your fly!
The nymph got a bite,
An involuntary cry!

You tickled illegally,
And landed a beauty!
Caressing it's length,
as befits your sworn duty.

The fishnets are full now,
The skin glistens within,
You know that's it wrong,
OH! This must be a sin?

Yet, the flesh seems so tempting,
The trout's coming with me,
And we'll honour it's memory,
There's fish on for tea!
