The boy, left alone in the house, seizes the opportunity to satisfy his teenage urges. He locks the door, his heart pounding with anticipation. He pulls out his cock, already hard and eager, and begins to masturbate. He thinks about the girl next door, her laugh, her smile, her curves. His strokes become faster, more intense, until he can't hold back any longer. With a low moan, he comes undone, his body shuddering with pleasure.
