A shy, uncircumcised teen explores his body, gently pulling back his foreskin to reveal the sensitive tip. His small penis, barely a few inches long, twitches with excitement as he begins to wank. He's tentative at first, but soon gains confidence, his strokes becoming more rhythmic and sure. His breath hitches, and his body tenses as he nears climax, a small bead of precum forming at his slit.
