The room is filled with the rhythmic sound of flesh against flesh as a solo explorer indulges in his private passion. His strong hand works his rigid cock with practiced ease, the lubrication from his leaking tip aiding his movement. His eyes are closed, lost in his fantasy, his body tense with desire. The air grows thick with the scent of his arousal, and the taste of his pre-cum on his fingers only serves to heighten his senses. Finally, with a guttural moan, he finds his climax, his cock pulsing as he coats his hand and stomach with his hot, white cum.
