It was a hot summer day and I had come into central London for a day of window shopping and socialising. Because of the weather, I had decided to wear my favourite light summer dress. I am fortunate in that I can get away without wearing a bra if I want to, and today was one of those days where to be free of restraint was very appealing, however the material of my dress was quite thin and sheer and to go without anything underneath would have resulted in a lot of attention, so I elected to wear a lacy camisole underneath. That way I could enjoy the freedom of being braless without drawing undue attention to myself.
I had a lovely day with my friends but eventually it came to an end and we parted company after a lovely late lunch in the Tate Modern. I was heading towards Shepherd Bush as I wanted to carry on window shopping in the Westfield Shopping Centre. I decided to enjoy the weather a little more and walk over the river to St Pauls to catch the tube. As I walked I noticed a guy looking at me. He smiled but I blanked him and continued to walk. He was a reasonable looking guy, but I was just trying to enjoy the day, so I didn’t want to give him any encouragement.
I crossed the Millennium Bridge luxuriating in the feeling of the gentle river breeze caressing my skin and providing a welcome relief from the still hot sun. I stopped halfway across to admire the view and as I did so, I looked to my side and noticed the same man who had smiled at me, also stopped looking out over the Thames just a short distance from me. As I watched him, he turned to me and smiled again, this time with more than a hint of a leer on his face.
Suddenly, my mind was in turmoil. Was it just a coincidence or was he following me. It seemed unlikely that he had accidentally stopped at the same time as me. I didn’t feel scared -- just strangely excited but for reasons I couldn’t understand. I broke his gaze and resumed my walk, still at a walking pace but with a modicum more urgency.
I descended into the hot, sticky tube station of St Pauls and headed for the Westbound Central Line. It wasn’t quite rush-hour, but the weather must have driven a lot of the city workers home early because the station was packed with people. I do not suffer from claustrophobia, but I do like my personal space and it was clear from the number of people purposefully striding towards their platforms that personal space was something I may need to forego for a while.
The heat rose unbearably, only alleviated momentarily as the trains pushing through the tunnels blasted a jet of air out into the tunnel system. All around me was the smell of hot, sticky bodies. My light summer dress started to cling to me as my own perspiration started to take its toll. I waited patiently with my fellow travellers for the next train to arrive.
When it finally burst out of the tunnel, it was clear that this was not going to be a comfortable journey as most carriages were already heavily loaded. I managed to jostle and push my way into the nearest carriage and resigned myself to my fate. Anyone who uses the tube regularly knows what it is like -- just something you must put up with. In fact, I actually find it fascinating how civilised most commuters behave in very uncivilised circumstances. How we all unconsciously participate in this secret ballet of shifting weight around and trying to find your own comfortable spot within the mass of human bodies.
However good you are at this, on days such as this, you know that unexpected contact with strangers is unavoidable and nothing to worry about, so I was unconcerned when I felt a warm body pressed against my buttocks and lower back and my breasts crushed up against a lady in front of me.
The train left the station and as it lurched and rolled, our bodies followed its lead and bumped and grinded against each other as usual, but then something felt odd. The ill-defined, general pressure against my bum changed. It became more defined and specific and -- well - harder! Not only that, but the hard, sausage shape lump nestled between my bum cheeks was no longer moving purely in response to the train’s motion, there was a definite, rhythmic thrusting against me.
It was clear what was happening. I was surrounded by strangers and someone I couldn’t see was dry humping my bum. I tried to turn round but the crush of bodies prevented me from easily doing this, however I managed to crane my neck into a position where out of the corner of my eye I spotted the guy who had followed me. He still had a big smile on his face and being seen did not result in any change in his rhythm.
I probably should have screamed and made a fuss. There were plenty of people around me who could have helped me but instead of feeling outraged and scared, I discovered that my pussy was soaking wet. I was aroused -- REALLY aroused. A stranger who had slightly spooked me just a few minutes previously was using me for his own pleasure in public, seemingly with none of my fellow passengers being aware of what was happening literally inches from them.
I SHOULD have screamed. But I didn’t.
Instead I faced forward and enjoyed the attention.
We pulled into Tottenham Court Road and the carriage occupants reconfigured. Some got off, more got on. Same crush, different people, slightly different position. But still I could feel this strangers cock drilling into my backside. As the train left the station and the people around me busied themselves on not looking at anyone in particular, the grinding restarted, but this time I felt something different. This time I felt the material of my dress being lifted and a hand sliding down into my knickers.
Still no-one around me showed any sign of being aware of what was happening to me and still I felt inexplicably aroused by this invasion. I felt the hand sliding my knickers down to just below my buttocks and then a finger exploring the crevice between my cheeks. The finger tickled and stroked the entrance to my anus for a while and then was removed and replaced once more by the trouser covered erection, this time rubbing directly against my skin.
The newly freed hand however managed to find a route around my waist and before I knew it, the front hem of my dress was lifted, and the hand found itself inside the front of my knickers. I felt it moving downwards until it eventually parted my lips. At this point of course, my assailant would have felt how wet I was -- soaking wet. My underwear was soaking too. In this instant, he knew for certain that it was not fear that stopped me exposing his actions, but pleasure. His hand sought out my clitoris and started to stroke it. I wanted to cry out with pleasure, but I had to bite my tongue.
