I love jerking off on the train too! Especially on the way home, I'm so horny on the train. I pull out my fat cock and drop a juicy load of cum on the seat next to me!
I admire the control you showed in this video. If there weren't any people around, my pants would have been down, and I would have been shooting out a nice sperm load into a paper towel right there I would have been so aroused.
