Under the scorching sun, a lone man finds solace in his own company, a bottle of protein-packed water within reach. His hand strokes his thick, veiny cock, the sensation enhanced by the cool liquid on his skin. He takes his time, exploring every inch of his hard, throbbing length, pausing only to take a sip of his drink. The water dribbles down his chin, mingling with the pre-cum on his dick, creating a slick, slippery surface for his hand to glide on. His breathing grows ragged, his strokes more urgent, until he finally spills his load, the semen mixing with the water in his glass.
