A man, alone in his home, decides to experiment with a new masturbation technique. He positions himself on a chair, facing the ceiling, and begins to stroke his erect cock. The angle allows him to watch his own body, a unique perspective that heightens his arousal. As he picks up speed, his moans fill the room, echoing off the walls. His muscles tense, and with a final thrust, he reaches his climax, ejaculating upwards, the warm liquid coating his stomach and chest.
