Katherine's feet, clad in tiny bikini bottoms, are the focal point of her ticklish torment. Her captor's skilled fingers dance across her arches, tickling her toes, and teasing her heels. Katherine's laughter echoes as she tries to pull her feet away, but the rack holds her fast. The tickling moves to her calves, then her knees, each touch sending electric shocks of pleasure-pain through her, her bikini-clad body writhing in delightful agony.
