Braving the cold, our solo explorer steps into the open-air shower, his hard cock already at attention. He grips it firmly, the soap providing slick friction as he pumps his hips, his balls slapping against his hand. The cool air contrasts with the heat of his body, his skin prickling with goosebumps. His moans mingle with the sound of the water as he nears his peak, his cock pulsing in his hand. With a final thrust, he spills his load, the white streams contrasting against the dark stone floor, leaving him breathless and satisfied.
