Rui, alone with his thoughts and desires, retreats to the privacy of his room. His hands, tentative at first, begin to explore the contours of his body, fingers tracing the lines of his muscles. His breath hitches as he grasps his hardening cock, stroking it slowly, building a rhythm. His moans fill the room, echoing off the walls, as he imagines unseen hands joining his own, pushing him closer to the edge.
