Marquinhos, in the throes of self-pleasure, grasps his hard cock, pumping it feverishly. His hand, slick with pre-cum, glides along his shaft, his eyes rolling back in ecstasy. He lets out a throaty groan, his body tensing as he reaches the point of no return. His cum splashes onto his hand, coating it in his warm, sticky release, a satisfied smile playing on his lips.
