The boy, in the throes of puberty, discovers the pleasure of his own body. He tentatively wraps his hand around his erect cock, feeling the smooth skin and the pulsing vein beneath. His strokes are slow at first, exploratory, but as the pleasure mounts, he quickens his pace. His free hand wanders, tracing the contours of his lean body, pinching his nipples, and finally cupping his balls, adding a new dimension to his pleasure. His body tenses, his grip tightens, and with a low moan, he finds his release, his cock pulsing in his hand as he comes undone.
