Meditation on the Letter 'S'

Shhhh! Sometimes swans seek serenity, sailing slowly seaword so silently. See? Subtle sorcery still smothers slugging sentiments. Sadly, sundown sinks solar safaris, sending suckers southward. Sin surrounds sex, so simpletons say. Sick! Such santimoniuous seasons seem senseless, sequestered sans syrup. Since September, seven Samurai shiver simultaneously, shaking swords supurbly. Snakes sound silly, swishing sangria; some swill Singapore Slings! Symbolic smooching? Simulated sympathy? Sucks!
