A mature gentleman, his body a canvas of time and experience, lies naked and vulnerable, yet eager on the cold stone slab. His weathered cock lies heavy and thick against his thigh, throbbing with anticipation. A pinwheel, its teeth wicked and precise, is his tool today, a dance of discipline and desire. He rolls it over his skin, gasping at the sharp, sweet pain, before bringing it to his cock. The metal bites, drawing a bead of pre-cum, as he loses himself in the exquisite torment of his solo session.
