As the train pulled into the next station I sat there nervously hoping no one would enter my carriage. It halted at the platform and my heart stopped as I saw a group of about thirty passengers standing there, right by my carriage. I could hear the carriage door open and a large group of people boarded and the carriage filled up quickly. A woman and a girl who I guessed to be her daughter sat down in the seats opposite me. I felt very exposed and very uncomfortable with my vest pulled down tight over my penis; its outline clear through the thin material. The girl who was in the seat directly opposite me soon noticed this and after looking at my crotch for a few long seconds looked up at me and gave me a big grin, I smiled back at her rather lamely and my penis gave a twitch as the vibration of the train started to cause another erection. After a short while my erection under the vest was very obvious and the girl who appeared to be around seventeen years old or so was watching with great amusement and was obviously enjoying my predicament.
I cursed myself for not having got my rucksack back down off the luggage shelf when I had the chance. At least I could have placed it on my lap to save my embarrassment, but I hadn’t, and, as is usually the case, there was a side of me that was enjoying this exposure enormously and it was keeping my penis rock hard and on full display beneath my thin vest. The mother didn’t appear to notice me and appeared to be napping, at least I assumed she was as her eyes were shut. The girl, on the other hand, was obviously enjoying the view and kept grinning at me. The motion of the train was having a serious effect on my penis, and I could feel the inevitable starting to happen, slowly my precum began to ooze from my tip creating a damp patch on the vest and then I started to feel my penis start to pulse as orgasm approached. I couldn’t stop it from happening, and without any further warning my cum started to spurt under my vest creating a spreading wet patch all around my crotch and on my tummy. I looked toward the girl and she was staring transfixed, watching me cum. I was shuddering with orgasm and as it passed she looked me directly in the eyes and gave me a smile, then, looking toward her mother as if to make sure she wasn’t watching, she passed me some tissues from her bag indicating I might like to clean up. I accepted the tissues gratefully and as she watched I lifted my vest and started to clean my penis and tummy of my cum, and then finally wiping my balls. When I finished I looked up at her and her eyes were fixed on my penis which was still very large but softening as she watched. I smiled and looked around to see if anyone was looking. Her mother appeared to still be sleeping and none of the other passengers appeared to be taking any notice. I screwed up the tissue which was soaked in my cum and dropped it to the floor of the carriage. As I pulled my vest down to cover myself again she bent down and picked up the wet tissue and put it in her bag looking at me and smiling as she did so.
The train was now approaching my station; it was three stops from London Bridge which was the end of the line. As the train slowed down, the mother appeared to wake up and looked in my direction, the look on her face seemed to indicate she had only just noticed me sitting there and she stared at me for a few seconds appearing to take in my lack of clothes. She glanced at her daughter who was intently staring out of the carriage window and then stared back at me again; the look was one of disapproval and disgust. I wanted to get off the train here but there was no way I was going to be able to stand up without exposing nudity to the whole carriage, particularly when reaching up for my rucksack from the luggage shelf. On the other hand I could remain until the end of the line at London Bridge then get off when the carriage was empty but I how would I manage at such a busy station, I had no chance so making a quick decision decided to get off at my appointed station regardless of the consequences. My plan was to wait until the train had stopped at the platform then quickly get up grabbing my rucksack and dash off as quickly as possible.
The train stopped and nervously I jumped up from my seat. The mother and daughter looked at me in total surprise and as I reached up to the luggage shelf my vest exposed me completely nude from my navel downward. I could see the girl was grinning, but the mother started shouting at me and gave me a very hard slap across my bare buttocks. By this time everyone in the carriage had noticed me and grabbing my rucksack I ran as quickly as possible to the nearest door and on to the platform. I could hear shouting, hoots of laughter and wolf whistles behind me. I was on the platform now and many faces at the windows of the carriage I had just left were staring at me, I didn’t hang around and as the train started to pull off I dashed into the nearest gents toilet to try and work out a plan for getting from the station to my apartment, which was about a half mile walk. I hid in one of the cubicles and heard the train leave the station; what could I do now? I was completely naked from my belly button downward and no possible way of covering my nudity adequately.
I was trying to work out what to do when I decided to remove my running vest and see if I could in any way use it to cover my nudity. I slipped it off and holding it in front of me realized that if I pulled it over my head and put my arms and head through the neck space, I could pull it down to my waist and make a skirt of it. So, quickly, I did just that. Luckily it was tight around my waist and covered my bum and penis adequately. I slipped my rucksack on my shoulders and walked out onto the platform, there weren’t many people around and no one seemed to pay me much attention. I reached my apartment about ten minutes later, very relieved and feeling quite a buzz from the excitement of the last two days.
