Gator Got Her

Paula Decker is a feisty young NYC diner waitress. An accidental
misstep on the way home one night lands her chained to a wall in the
watery sewer lair of the Gator Man! He cannot speak but communicates
his lust-filled desires in other ways, forcing Paula to overcome her
fear and revulsion of the creature as she submits to his unexpectedly
tender and arousing advances.
