Strapped to the chair, his eyes are forced to remain open, fixed on the erotically charged dance of his mistress's feet. She slips off her heels, revealing her bare soles, and begins to paint his body with her feet, marking him as her property. She grinds her heels into his muscles, leaving deep, satisfying indentations. He moans, his cock straining against the restraints, as she finally, mercifully, presses her feet against his pulsating cock, giving him the friction he craves, bringing him to the brink of ecstasy.
