In the dimly lit, private sanctum of his room, a young man, unseen and unheard, gives in to his primal urges. He strips naked, his cock already hard and throbbing. Sprawled on his bed, he grips his thick shaft, stroking it slowly, feeling every vein, every pulse. His other hand wanders, caressing his balls, teasing his ass, as he imagines the touch of another. His pace quickens, his breath hitches, and with a low groan, he releases, painting his chest with hot, sticky cum.
