On the trains we used to have in Melbourne they had a seat right across the end of the carriage for 6 people and in front of that were as seat for 2 people and a seat for 3 people. There weren't many people in the train at night in those days.
I was catching the 11.15 train home at night after knocking off work.
I was sitting at one end of the carriage and at the other end there was a girl on the end seat, sitting behind the seat for 3 people and a bloke sitting on the seat for 2 people.
I was having a smoke and looking to wards the girl at the other end of the carriage, she had a light dress on.
Very soon after the train left Flinders street station the girl gave me a sort of backward nod of her head to beckoned me to go to her end of the carriage.
I gathered my bag up and headed down to her. Her first words were "Have you got a smoke" so i gave her a cigarette and lit it for her, she told me it was her 18th birthday.
I then put my left arm around her and she seemed quite happy with that and so I put my right hand on her knee and there was no objection so I slid it up to her pussy and pulled her panties aside and fingered her clit and put fingers in her pussy and she was back and forth fucking my fingers. She put the smoke out and then removed her panties and put them in her bag and then rubbed my cock through my trousers. This all seemed good and I was thinking maybe we should go somewhere else for a fuck so I said to her "Where will we get off" she replied "I get off anywhere I want" I said "What about we do it on the train". She got my cock out and she sat on it with her dress covering what we doing, except for the up and down movements as she held onto the rail at the top of the seat in front. I think we had disturbed the bloke sitting on the seat for 2 people as he kept glancing around from reading his paper to see what was happening. After she seemed to be done and I had cum, she hopped off me, I put my cock away and she sat next to me again (she didn't put panties back on). I said to her "can we get together again" she said "if you see me you see me, if you don't you don't" and got off at the next station.
Never saw her again, I wish i had, it was lovely.
