Word Challenge: Thirst

I can feel it, the sharp, parched cry at the back of the throat
The tongue swollen, dry, hopeless
As I feel the need from deep, deep, deeper still
Body forcing, forging ahead despite
The mind aching to stop
Negotiating, wheedling, demanding
Step after
Step after
Step
I plod on
Fists curled,
Nails dug into palms
The thought of water, of refreshment,
Of relief
Getting farther behind
Yet with every step
Closer ahead.
