God he was bored. And lonely. Being the only living thing on the planet (besides some potato sprouts) really sucked. Mark lay in a cot watching an episode of million dollar man for the… Eighth time? He kinda lost track. What was important was he had nothing to do but lay around and watch the same thing over and over. He turned over and sighed to himself. Might as well give himself something to do. His hand slipped down his pants as he mindlessly messed around with himself. He hummed as he firmly stroked his now erect length. I really miss the internet, he thought. His pace slowly but steadily quickened until he was rocking his hips into his hand, gasping and moaning quietly. The Martian set down the rerun as he now focused on his newest endeavor. "Fuck," the breathy moan slipped between his lips as he now bucked his hips. His small sighs turned to loud moans as he could feel his cock throb in his grip. Watney grunted as he came, watching the spunk spurt unexpectedly far before seeping into the dirt in the Hab. Gross, he thought as he resumed watching the episode.
