A Fisherman's Secret

There is a secret, known to very few
But to all the fishermen and their generations, through and through

Many will see by the lake, is the big docks
But in their pants, giant cocks

Throbbing, pulsating, yearning for more
Like a rainbow trout, washed up on shore

These fishermen make little money at work, only tens and fives
But when they come home, they bring a treat for their wives

These fishermen keep their secret hidden well
Few to see it, and even fewer who tell
