Vinicius, a man of insatiable lust, finds himself alone in his apartment, his cock throbbing with untamed desire. He strips naked, his thick, veiny member standing erect and proud, a testament to his pent-up sexual energy. With a groan, he wraps his large hand around his shaft, starting a steady rhythm, his hips bucking in time. His other hand cups his heavy balls, rolling them gently, imagining the warm, wet mouth of a lover. His strokes quicken, his breath coming in ragged gasps, his body tensing as he nears the edge. Suddenly, he freezes, his eyes wide, as he hears footsteps outside. Quickly, he pulls up his pants, hiding his still-hard cock, just as the door opens.
