I was really late for work - I’d overslept, or rather I’d stayed in bed playing with myself far too long - and I’d dressed in a massive hurry. The office where I work is quite strict about appearances, since I have to do quite a bit of entertaining as part of my job. So its important that I look presentable, and in the rush of ironing my silk dress it seemed I had quite forgotten to put on any knickers! I realised this as I was walking to the station - my previous activities had left me in a bit of a creamy state, and I could feel myself becoming even more aroused as I joined the crowds in the ticket office, knowing that only a thin layer of silk lay between their eyes and my puffy wet pussy. The men around me were all looking, taking in the curves of my breasts and hips which were accentuated by the tight fabric. I could feel the heat of their glances, and to my shame my nipples hardened beneath my dress. The flimsy lace bra I’d picked up off my floor did nothing to disguise them, and they stood proud before me, outlined in pale pink silk. An oldish man with a stick caught my eye and licked his lips lasciviously, and I blushed - I felt like such a slut. I bought my ticket and hurried to the platform to catch my train. As usual, the carriage was ludicrously overcrowded, even before it pulled into the station. About twelve of us tried to get into a space big enough for two. I ended up with my face in some guys chest, and numerous elbow, knees and shoulders pushing into various parts of me. I tried not to breathe and waited for the train to leave. Almost as soon as it did, I became aware of a hand on my bum. I get groped on the train all the time - they are so overcrowded I’m sure its unintentional half the time, but you do get the odd guy who will take advantage and cop a proper feel. But at half seven in the morning, in the deadly silence of the commuter train, I don’t normally like to create a scene. I take the view that if it makes an old perv happy, then so be it (and I normally have a good wank later on imagining what could have happened). So I didn’t do anything at first about the hand. I analyzed it - it was moving very slowly across my left buttock. It felt hot through the silk, but gentle, and so I let it continue. Within seconds there were two hands, one on each of my buttocks, circling around them and finally cupping them. My face by this point must have been bright pink, and the guy whose chest I was facing had blatantly noticed my nipples poking into his midriff, as he had started to move slightly against me, rubbing them till they were swollen and so sensitive I could barely breathe. This double groping was a new experience for me, but I felt so horny there was no way I was going to say anything to make them both stop. Without any warning, the man behind me started to slowly edge up my dress, until I could feel his fingers on the underside of my bum, then under the dress and all over, slowly but deliberately taking in every inch of my flesh. I looked around me at the other passengers, wondering why no-one had noticed, and I realised that the eight or so round about us were all men, and despite the fact they all appeared to be looking the other way, I knew they were all watching. The hands on my bum withdrew for a moment, and the new danger in front of me suddenly realised itself in the form of a quick fumbling and then a large, hot, hard erection which pressed into my bare thigh. I couldn’t believe what was happening but my pussy was dripping with the dirtiness of it all, and I allowed him to manoevre me slightly so the thick base of his cock was right against my slick swollen clit, circling and spreading my juices all over my puffy pink shaved mound. Then I became aware that the man behind me had also been freeing himself up, and his hands returned to greedily clutching at my bum cheeks whilst his dick pointed straight into the crease and nestled there, his big bell-end probing gently at my oozing labia. I could feel his breath on my shoulder and the urge to push my hips back and get that cock inside me was almost more than I could bear but I stood perfectly still, with my clitoris and nipples on fire from the frontal massage I was getting, and the constant threat from the cock between my legs. By now my pussy was making little sucking noises as he pushed back and forwards against my hole, and I heard his breath quicken. I realised that if I didn’t get it up me soon, it would be too late, so I arched my back and let him enter me, his cock stretching my soaking wet hole wide. He thrust hard into me maybe seven or eight times before he grunted and I felt his meat spasm inside me, filling me with his cum. As he pulled himself out of me, I could feel dribbles of it on my thighs, and his fingers reached underneath and spread it all around my pussy, and along my crack to my asshole, where he ever so gently inserted his index finger. The guy in front had been rocking against me the whole time, his cock right on my clit driving me silently insane.Now he pulled me up onto my toes and onto his massive fat dick. He was so big that it was a very tight fit despite the fact I’d just had a load up me, and as he angled himself and stroked deep against my g-spot, the man behind me stroked his spunky finger in and out of my bum. I could barely hold back any longer, and when I heard a whisper in my ear “Come, you filthy bitch”, I did. My pussy exploded and at the same moment, the cock inside me bucked and throbbed and I felt a whoosh of semen filling me up. In a flash, my dress was pulled back down again, flies were zipped up, and the inscrutable commuter poses re-adopted. Several minutes later, the train stopped at my destination, and I got off, somewhat flustered. As I scrabbled about in my bag at the ticket gate, I noticed the old man with a stick walking up the platform, and as he passed me, he smelled his finger and licked his lips again like he had before. I felt physically sick, but it wouldn’t be the last I’d see of him.
