A mature nudist, basking in the sun at a secluded naturist beach, can't resist the temptation to tease himself in the open air. His uncut cock, already semi-erect, throbs as he gently strokes his foreskin, revealing the sensitive glans to the warm, salty breeze. He leans back, eyes closed, enjoying the sensation of his own touch, his body tensing as he edges closer to release.
