In the dimly lit room, a young, athletic man, a gym fanatic, takes a long drag of his cigarette, the ember glowing in the semi-darkness. He's alone, but the sensation of the smoke filling his lungs and the nicotine coursing through his veins sparks a different kind of desire. He unzips his pants, his hard cock springing free, already leaking pre-cum. He strokes himself, his hand moving in rhythm with the drags he takes, the ash falling onto his abs, mingling with the sweat. The room fills with the scent of smoke and sex, the sound of his hand moving up and down his cock, the wet, sloppy sounds of his pleasure. He moans, his body tensing as he nears his peak, the cigarette hanging forgotten from his lips. With a final, shuddering breath, he comes, his cum mixing with the ash on his stomach, his body relaxing as he takes one last drag before putting out the cigarette.
