The boy's heart races as he hears the faint sound of his neighbor's window sliding open. He's been caught, but instead of being embarrassed, he feels a thrill. He's been craving this moment, masturbating to the thought of her watching him. He turns slightly, giving her a better view, and begins to touch himself. His hand wraps around his cock, feeling its hardness, and he starts to stroke, his hips moving in rhythm. He can almost feel her gaze on him, her breath hitching as she watches. He picks up the pace, his body tensing, and with a final, loud groan, he comes, his cum shooting out, painting the wall with his desire.
