Occasionally I would spend the weekend in London and I would head off to Hastings on the South Coast of Sussex where there was a nudist beach I had heard about. On my first visit I took the train from London, it was a Saturday morning and I took a small rucksack with me for essentials such as cash, G-string, towel, sandwiches, beer and a map etc, I wore a skimpy running vest and a very tiny pair of loose fitting white nylon shorts which were almost completely see through leaving very little to the imagination.
When I boarded the train in South London, I felt maybe that I had gone a little too far with the shorts, my penis kept flopping out through the leg and they were almost see through so everything was visible if anyone cared to look. At first I felt a little uncomfortable but after a while I decided what the hell just go for it. I got a couple of dirty looks from a few people but otherwise no-one seemed to notice so I settled down on the train for the short journey to the coast. The trip was pretty uneventful apart from two girls who joined my carriage at Sevenoaks, the carriage was quite full and when they sat down opposite me I had to quickly try and rearrange my shorts to try and cover myself. The problem was that the vibration of the train was causing my penis to become erect and this was becoming evident through the thin white nylon of the shorts, my singlet was too short to pull down to cover me so I just had to sit there hoping my shorts could contain me.
The girls quickly noticed my predicament and were giggling and staring at my bulging crotch and the clear outline of my erect penis. To make things worse the precum on the tip of my penis was making a little wet patch and this was making the nylon transparent at that point. Throughout the journey my penis stayed erect and as the train arrive at my destination I realised I had another problem, I was going to have to get up to get off the train and the two girls opposite knew this and were watching me with anticipation.
If I stood up there was no way I could hide my penis and it would protrude from under the brief piece of nylon currently covering it. Furthermore the back of my shorts during the journey had pulled up and I could feel that my buttocks were almost completely exposed. I decided that the best thing to do was just stay seated after the train arrived and wait until everyone else had alighted. The train pulled into the station and as this was the end of the line there was no hurry to get off, so I sat and waited for all the other passengers to depart. I still had a raging erection and by now the tip of my penis had pushed the foreskin back making me even harder as the wet patch of precum spread across the front of my shorts.
All the passengers had alighted but the two girls opposite me were still there, they were smiling at me and obviously waiting for me to move, so I thought Ok here goes. I stood up to get my rucksack from the overhead baggage shelf and as I did I felt my penis pushing back the nylon of my shorts, and as I reached up I felt it burst out from the constraint of the thin nylon material. I was now completely exposed to the two girls who just stared in silence at my erect penis and balls (they too had flopped out and were fully exposed). I stood facing the girls; they continued to stare and said nothing.
"What are you going to do about that?" asked one of them without taking her eyes from my penis.
My penis was only inches away from her face, I didn't reply but nervously looked around, there was no-one nearby so taking a firm grip of my erection I started to masturbate as they both watched, their eyes completely focussed on the exposed tip of my penis. I was so excited that in a very short time I could feel the familiar sensation as my penis started to throb and pulsate, I clenched his buttocks tightly and with one final stroke thick hot white cum erupted from the tip and spurted all over the clothes of my audience. The girls were too mesmerised to say anything, and just stared open mouthed as I squeezed the last drops of cum from my still erect penis.
The two girls just sat and stared at me in silence as I quickly rearranged myself and did my best to make the shorts decent again; I held the rucksack in front of me as I got off the train to hide my still very obvious erection. The girls were still sitting there as I got out of the carriage and as I gave them a little wave, they responded back with big grins and made wanking motions with their hands, I grinned back at them and made a rapid exit.
Back in the carriage the girls looked at each other, they were stunned at what had just happened, and as they each noticed the cum splashes on their clothes, they burst out laughing.
"I wonder what it tastes like," said one to the other as she scooped up cum from the leg of her friend's jeans.
Outside the station I decided to go to a nearby pub and study the map in order to work out how to get to the nudist beach. There was a pub next to the station so I went in got a pint and stood at the bar and studied my map. There were a couple of other people in the pub and after a while one of them, an attractive woman in her 30's came up to the bar and sat down next to me. At first she said nothing but I could sense that she was looking at me, I took a swig from my pint and briefly looked in her direction.
"They don't leave much to the imagination do they," she said with a big grin.
I looked at her quizzically, she grinned and pointed to my shorts and as I realised what she meant I made a lame attempt to rearrange them but only succeeded in exposing more of my bum.
"Oops," I said, "I didn't realise they were so small," she grinned back at me, then looked over at my map.
"Where are you planning to go?" she asked. When I told her I was going to the beach at Fairlight Glen, she smiled knowingly and stared again at my shorts.
