The boy, driven by primal urges, takes his engorged, prepuce-covered penis in hand, pulling the foreskin back and forth with increasing speed. His breath hitches as he feels the pleasure intensify, his balls tightening in response. He lets out a guttural groan as he reaches his peak, his cock pulsing as it releases a thick, milky load, dripping down his shaft and onto the floor, a testament to his intense solo indulgence.
