An eventful journey

A couple of months ago I was on my way to a friends house, travelling by train. It was rush hour and very crowded. By the time I got on it was standing room only, so I squeezed my way into the carriage and stood crammed together with the rest of the passengers. After a few stops I was aware of a hardness poking into my buttocks. 'Oh my God' I thought, 'The man behind me has got an erection'! As the train swayed on and our bodies rubbed against each other, it became obvious he did! I found that instead of trying to move away, I was deliberately pressing myself to him and allowing the movement of the train to slide my buttocks over his cock. Suddenly I felt his hand caressing my bottom before it slipped up my skirt and between my thighs. I leaned forward and opened my legs slightly to allow his easier access to my pussy,which by now was very moist. I felt his fingers move up and down my slit through my knickers then slide them under the material to my naked pussy lips. He parted my lips with his fingers and found my pussy hole. A finger slipped inside and then another. The movement of the train was allowing his fingers to slide in and out of my pussy hole. Then he took them out and moved them up my inner lips to my clit and began to rub it. I was so turned on I came right there on his hand, trying not to cry out. He then held my hips tight to him and rubbed his cock against me, I could feel how hard he was and rolled my hips against him. I could hear him breathing heavily in my ear as he came too. When we pulled into the next station some passengers got on, some got off and we got shuffled around. I dont have any idea whether he got off the train or whether he was there until I got off, I never even saw his face, but I was a sticky mess by the time I got to my friends and Im pretty sure he was too when he reached his destination!
