The heavy silence is broken only by the soft, rhythmic sound of flesh against flesh as the uncle guides his nephew's hand, showing him how to pleasure a man. The nephew's inexperience is evident, but his enthusiasm is infectious, his breaths coming in short gasps as he takes in the sight and feel of his uncle's cock. The uncle, his voice barely a whisper, instructs his nephew to use his other hand, to cup his heavy balls, to feel their weight and fullness. The nephew complies, his small hands working in tandem, bringing his uncle closer and closer to the edge. As the uncle's body tenses, he warns his nephew, but the young man, eager to learn, keeps going, his hands working feverishly until the uncle's hot cum spills over, coating his nephew's hands and staining his innocent sheets.
