As the sun dips below the horizon, casting a warm, amber glow over the city, a young Brazilian man decides to indulge in a little self-pleasure. A "soloboy," he's no stranger to the touch of his own hand, but tonight, he's especially horny. His cock, a "pau duro," is rock hard and aching for release. He strips off his clothes, the cool air of the room contrasting with the heat of his body. He strokes his cock, feeling the veins pulse with desire. His moans fill the room, echoing off the walls as he brings himself closer and closer to the edge. Just as he's about to come, he hears a noise at the door. He freezes, his heart pounding, as he sees the silhouette of someone watching him.
