TRAIN - MF [short story about guy finding exhibitionist girl on train.] I'd just had lunch with my girlfriend in the city and was traveling home on the express train. There were not many people around and the part that I was in was empty. Just as the announcer said 'doors closing' a young girl jumped into the train and sat opposite me. I guessed she was about 18, with long black hair and a pretty face. She smiled at me as she looked around. She was wearing a typically young short top, with thin straps. It must have been made of very thin material coz I could see the outline of her perfectly formed tight young breasts. I could feel stirrings in my groin, especially when my eyes also moved lower. She had gorgeously long bare legs which she'd already crossed and her skirt, what there was of it, was so short that I could almost see right up to her underwear. After checking out the rest of the carriage, she looked back at me very directly, with a sweet inviting look on her face. By now my cock had erected fully and I had to shift to get comfortable. I noticed her eyes look down and open wide when she saw the now large bulge. She grinned again and I could see her nipples were now erect and sticking through the material of her top. She looked down, following my eyes and smiled, moving one hand to her left breast and caressing her nipple erotically. Now my cock throbbed painfully inside my clothes. She definitely knew what she was doing to me, especially when she now slowly uncrossed her legs. With her skirt already so far up her thighs I could clearly see the lovely triangle of her white panties. I had to move again to straighten up my cock which I could see was now curving right across my waist. Her eyes were wide open as she watched it grow to it's final huge size. She then got up and went through to the toilet at the far side of the carriage. I had calmed down somewhat by the time she returned and sat down on the seat again, immediately crossing her legs once more. What she did next made me instantly erect again. She put one hand down on the seat beside her, as a closed fist. Then after making sure I was watching her, she slowly opened her hand to show her white panties screwed up into a ball. I was so excited by this that I almost came in my shorts. I looked up at her face in disbelief but saw that her eyes were focused directly on my crotch, where my cock was trying to escape from its confines. I smiled at her and my cock jerked wildly. This made her giggle, but then she very slowly and seductively uncrossed her legs. I tried hard to see but she soon gave me full opportunity by leaving her legs slightly apart. In the darkness between her thighs there was no sign of underwear now and as she slowly parted her legs further I could clearly see her beautiful naked and cleanly shaven pussy. I then felt the familiar surge running through my groin and I really thought I was going to cum. But somehow I managed to hold back but even so a dribble of cum must have shot out because a wet stain appeared on my shorts. She mouthed at me "I'm wet too!" and opened her legs even further, pushing her hand down between her thighs. She briefly played with her clit and then quickly pushed a couple of fingers inside her pussy. This made a delicious squelching sound and when she brought them out again she showed me that they were covered in her young cream. I wanted to pull out my cock and stroke it so that I could cum properly but at that moment the train began to slow down for the first station on this express line. I knew that it was a further 15 minutes to the next stop, but it was clear that she was going to get off here. She gave me a further thrill by spreading open her pussy lips for a moment and then closed her legs and stood up. She waved goodbye and was gone before I had time to follow. Luckily no-one got into the same compartment so I was able to take out my throbbing cock and relieve the ache that had built up before I had to get off. I came deliciously into some tissues.
