I took the train home the other evening, the carriage was quiet, I was on the left side and a man on the right side, a seat or two ahead. I noticed, out of the corner of my eye that he seemed to be fidgeting so I glanced over at him to see what he was doing. His hand was stroking his bulging crotch, he was obviously horny and couldn't wait to pleasure himself. I couldn't take my eyes off his blatant masturbation, especially when he unzipped his fly and released his stiff cock. Surprisingly he never turned around to see if I was looking but hopefully he knew I was watching. He stroked his cock up and down, he tilted his head back as he thrust his cock in and out of his hand. I could tell he was imagining fucking someone as his thrusts became harder and faster. Just watching him had got my pussy so wet, I began humping and grinding my seat to excite my pussy even more
Suddenly I could hear him moan as he turned away slightly, I knew he was shooting his cum on the train. He put his cock away as the train stopped and he got up to get off at his stop. As he passed me I gave him a smile to let him know I had watched every moment. As I was the only one left in the carriage I went over and sat on the seat where he had masturbated. I was so turned on by the sight of his fresh cum in a pool on the seat, I looked to see if anyone was about. I started to finger my throbbing wet clit as I began to smell his cum. But it wasn't enough to just smell it so I began licking his cum up off the seat as I played with myself, it was still hot and so tasty, I couldn't believe I was licking a strangers cum off a train seat, but I loved it! I felt so dirty!
