The train was delayed. Emma sat and gazed out of the window. It was a fine clear day, far too nice to be on the train to work. She sighed and turned back to her magazine. As she did she caught sight of the man opposite her. He was checking out her legs. She was sitting with her legs crossed. They were long, slender legs, wearing stockings and high heeled shoes.
Emma pretended she hadn't noticed him looking but her heart began to speed up. He was apparently reading a newspaper but she knew he was secretly looking at her. He was an older man, late fifties or early sixties, cropped grey hair, smart expensive suit. Emma looked at the wedding ring on his third finger. A married man, probably frustrated, no longer getting the sex and attention he needed. She was aware that she was becoming warm and slightly damp. She liked him looking at her. Both of them pretending it wasn't happening.
She gave a tiny wriggle and re-crossed her legs. Her skirt slid up her thighs a little way and she watched from beneath her eyelids as he took a good look. She imagined him storing up her image for later when he was alone. She imagine a bulge in those expensive trousers, his hand surreptitiously rubbing. The thought made her wet and she wriggled again slightly. Her skirt slid up further, revealing a lacy stocking top and part of a black suspender. The man held his paper very still. His eyes didn't move from her exposed thighs. Emma felt incredibly aroused as he looked at her. She wanted to pull her skirt all the way up and show him her lacy black knickers, which were becoming very wet. She made herself look away, out of the window, while at the same time she slowly uncrossed her legs. For a minute she sat with her knees primly together, then she let them part a little. She knew that from where he was, he could see straight up her skirt. She wanted him to look. Her whole body wanted her to spread her legs wide and pull them up, high heels resting on the seat. She wanted to completely expose herself to him and watch as he masturbated over her...
