Diving for Pearl

"If you touch it again
We'll no longer be friends"
She said, in the back of his car.

"Now don't be a tease
But do tell me please,
What direction to go and how far".

"Well you'll need both your hands
As we're stuck in the sand,
And I hope you can swim
As the tide's coming in!"

"Well how can that be?" and
As he looked out to sea,
She got out of the car,
Unhooked her bra and
Without thinking twice
Made a flotation device.
