The beast within unleashed, he grips his mammoth member, a steel rod veined with desire. He works it with skilled hands, spreading pre-cum to lubricate his strokes. His hips buck, fucking his fist, as he imagines the tight, wet heat he craves. The air is thick with his musk, the sound of his heavy breathing punctuated by the wet slapping of flesh against flesh. He's a man possessed, chasing his release with single-minded determination.
