The young '18 anos' is eager to explore his newfound liberties, starting with his own body. Alone and horny, he takes his time, touching himself tentatively at first, then with growing confidence. His cock stands at attention, ready for his touch. He grips it tightly, feeling the pulse of his own desire. His strokes become more urgent, more insistent, as he chases his release. His breath comes in short, sharp gasps, his body tensing as he gets closer. With a final, desperate cry, he comes, his cum spilling over his hand and onto the floor, marking his passage into adulthood.
