The teen's massive cock tenting his shorts is impossible to ignore. He teases the outline with his fingers, biting his lip. Slowly, he frees his length, letting it spring up, hard and ready. He runs his thumb over the sensitive head, collecting the bead of precum. His hand wraps around his shaft, starting a steady rhythm. He leans back, eyes closed, lost in sensation. His hips buck, fucking his fist as he builds towards release. His body tenses, and with a stifled moan, he comes, dick pulsing, painting his chest with white streaks.
