Shark Fin Sandwich

My need to enhance my virility 
The fin warns fish of fatal doom
My penis punishes my pants
It siphons the steaming ooze
Proverbial primordial pulp
Consumed with a hefty gulp
Its' shark 
Our portion
My potion
The potency of ill gotten gains
Tasting of happiness and euphoria 
Somethings are never fair
Never equal 
Always burning my tongue
