With a pounding heart and flushed cheeks, the boy locks his bedroom door, eager to indulge in his secret pleasure. He pulls down his pants, his cock already semi-erect, throbbing with anticipation. He wraps his hand around it, feeling the smooth skin, the pulsing vein. He starts to move his hand, slowly at first, then faster, his breath coming in short gasps. He imagines a beautiful girl from school, her smile, her laugh, her body. His hand moves faster, his grip tighter, until he feels the familiar tingle at the base of his spine. With a groan, he comes, his semen spilling over his hand, a satisfied smile on his face.
