Alone and horny, this solo explorer kicks back, his hand already working his stiffening cock through his jeans. With a hungry growl, he frees his erection, the cool air a stark contrast to the heat radiating from his body. He spits into his palm, lubricating his grip as he begins to stroke, his wrist twisting in a practiced motion. His other hand cups his balls, gently rolling them as his pleasure intensifies. His breath comes in ragged gasps, his body tense as he races towards climax. With a final, desperate pump, he comes undone, his cock pulsing as he paints his chest with his own hot, sticky desire.
