A well-built unknown man discovers me pleasuring myself in public and assists me in reaching climax

I was out for a stroll when I stumbled upon a car that seemed to be parked in the middle of nowhere. As I got curious, I peered through the tinted windows and what I saw made my heart race. A well-built unknown man, completely naked, was pleasuring himself. His big, firm hands were caressing his big, firm cock, each stroke bringing him closer and closer to the edge. I couldn't help but watch as he reached down and started to touch his pussy, his fingers exploring every inch of it. The sight was too much to resist and I found myself joining in, my own fingers dancing over my own pussy. It wasn't long before he came, his hot cum splattering all over his naked body. The experience was intense, a perfect mix of public exposure and masturbation that left me breathless.
