The young man, just a novinho, can't resist the urge to pleasure himself. He locks his door, ensuring no prying eyes will catch him in the act. His hands tremble slightly as he lowers his pants, his heart pounding in his chest. His cock, a generous 16cm, springs free, already hard and leaking pre-cum. He wraps his fingers around it, his grip firm and steady. He pumps his hips, fucking his fist, his moans filling the room. The sound of his hand slapping against his cock echoes, the scent of his musk heavy in the air. He comes undone, his cock pulsing as he coats his hand and stomach with his cum.
