With a hunger in his eyes, the solo explorer stands naked, his thick, veiny cock standing at attention. He runs a teasing hand up and down his length, feeling the pre-cum beading at the tip. He cups his balls, feeling their weight, before giving them a gentle squeeze. His other hand grips his shaft, stroking it with increasing urgency. He leans back, his body tensing as he nears his climax, his cock pulsing as he releases, his hot cum spilling over his hand and onto his body.
