Mario, a young, eager man, finds himself alone with his thoughts and a raging erection. He's always been curious about the power of his 20cm cock, and today, he decides to explore it fully. Pulling out his thick, veiny dick from his jeans, he begins to stroke it slowly, savoring the sensation of his hand against his sensitive skin. His breath quickens as he picks up the pace, his grip tightening around his shaft. Precum beads at the tip, and he uses it to lubricate his hand, allowing him to glide up and down his length with ease. His muscles tense as he approaches climax, his body convulsing as he spills his load onto the floor, a satisfied sigh escaping his lips.
