The Prickly Edge

There is a tang of saline and
It runs in the gutters of my mouth
Reminding me that I am thirsty
And although fresh water is nearby
I do not drink,
Choosing rather the prickly edge of desire
Over momentary satisfaction 
Choosing to abstain
With its yearnings and keening
Because it fills a different void
Elementally separate and distinct

That no simple sip of water can quench.
