A sadistic submission by an S man, titled "S Man." Utilizing night vision, this fetishistic production creates an intense, immersive atmosphere akin to a dark cruising booth. First, in total darkness, the submissive boy reveals himself through masturbation, building tension throughout. Then, it escalates beyond mere groping into full-on sex. This time, the spotlight is on Kazuaki, a full-body sensitive twink with a thick cock. In the pitch black, uncertainty and fear mount as lewd touches and sudden foreign objects are thrust into his anus, blending unbearable pain with overwhelming pleasure. His already wrecked hole is then invaded by the S man's huge dick, as his body is progressively defiled. In the darkness, the desperate moans of the violated twink echo alongside the S man's heavy, excited breathing.
