I masturbate in the train after a night out because I feel horny

First public video :) Filmed this back from a night out where I was horny as a dog. There were sleeping people scattered around but not paying attention so I decided to bust a fat nut before I arrived. It was kinda risky because you never know who might come (pun intended), you can see I wasn't very hard and didn't come a river but it was worth it. As I was climaxing we passed a major station at full speed but I could see people waiting and I hope they could see the moist tip of my pulsating dick ready to overflow. Would do it again.
