In a dimly lit room, a bound woman wriggles her bare feet, toes curling and uncurling as two unseen hands tease her soles with feather-light touches. Her giggles echo, turning into gasps of pleasure-pain as the tickling intensifies. Her feet squirm, trying to evade the relentless stimulation, but her bonds hold her in place. The tickler's skilled fingers dance over her ticklish spots, drawing out moans and laughter, a symphony of sensations that leaves her breathless.
