I got on a Tube train a few years back and a girl was sitting on the opposite side of the carriage to me in one of those of four seater bays. The train wasn’t full so we had a clear view of each other. She used that to her advantage. She was filing her nails so suggestively, glancing up every so often to see if anyone was looking at her; I was, intently. She was Rubinesque, well rounded, nice breasts showing at the top of her blouse, ruby lips and shortish brown hair. She was so fucking sexy; not sure what it was about her but she was sex incarnate. She glanced back at me and smiled. I just sat and watched her sexily file her nails for about 20 minutes. She crossed and uncrossed her legs then glanced up at me every so often, then we locked eyes and her offer of sex filled my body down to my cock and back again. We exchanged glances and smiles and intense eye searches. She was hitting my soul with her sexual flirting, it felt so fucking great. It was such delicious cock teasing. She wanted me and no one else. Then after all that time flirting she stood up to get off the train. She put away her nail file and walked towards me holding my intense look. As she walked towards me she smiled, then brushed my face with the back of her hand and squeezed my shoulder and beckoned me to follow her. I looked at her standing by the doors looking back at me. She looked at me and smiled and nodded. I sat frozen to my seat. She got off the train and looked longingly back at me. There was an element of hurt in her eyes. That was the end of it. I’d love to have the courage to do that again and take up the offer and go back to hers and fuck her. She could scratch my back with her manicured nails.
