A grizzled, experienced hand guides a younger, smooth one, teaching him the art of cock-to-cock rubbing. Their balls press together, the older man's heavy and pendulous, the younger's tight and firm. They grind, their feet entwined, the radio voice in the background narrating their every move. The friction is intense, their cocks leaking precum, the air thick with the scent of their arousal. They cum together, their asses clenching, the room filled with their grunts and the sound of their slick, satisfied moans.
