Many wondrous things can be achieved through the incremental gains technique. Blonde babe Whitney Fears uses it as her guide to achieving monster-dildo masturbation. First she uses regular sized toys which make her pussy sing with pleasure and get her nice and wet. That sets the stage for the next increase and she brings out a huge plastic dong.
Whitney brings out the over-sized dildo and caresses its massive girth while putting lots of lube on it. She lays back and slowly works the monster into her pussy, stretching herself to a new size. The sensation makes her moan uncontrollably, and her movements become more frenzied as she increases the depth of her strokes.
