It was an autumn evening and Katya walked along the train platform to the end; Mark was waiting for her. She smiled when she saw him and kissed his lips softly, looking into his eyes. He wrapped his arms around her waist clothed in a white silk shirt as she ran her hands round, inside his suit jacket.
"How was your day gorgeous?"
"Better for seeing you! I've been thinking about you all day..."
"Oh really? What about me?"
"What I'm going to do to you when we get home," Katya responded with a wicked glint in her eye.
It was true; Katya had spent most of the day at her desk daydreaming about that evening. For some inexplicable reason she had been very horny recently and intended to make the most of it. She'd been sending Mark provocative texts all day, to which he'd responded with just as much vigour.
Five minutes late, the train finally rolled into the station. It was rush hour and Katya and Mark managed to find a wall to squeeze themselves into amongst the rest of the commuters. Mark turned around so that he was face-to-face with Katya and kissed his lips. He gazed at her long dark hair, falling into natural waves around her soft face with those full lips he loved kissing so much. He felt himself become aroused as he looked at her top, suddenly realising that it was completely translucent. He could see the outline of the flimsy white lace that made up her bra and did a very poor job of supporting her breasts because they looked, to him, as though they were about to burst out of her top. His eyes scanned down the rest of her body to the flowing black skirt that ended at her knees and her nylon tights, down to her feet clad in entirely impractical shoes that seemed to be all 'tiny little heel'. He moved a little closer, unnecessarily, so that Katya could feel his growing cock against her thigh. She looked up, catching his eye and grinned. She rested her hand against his chest and felt for his nipple, giving it a little tweak. Mark moved his hand against her crotch area and applied pressure. Katya opened her eyes wide in protest, but as Mark pushed harder she melted into his touch, angling her body so she could feel the tips of his fingers more intensely. Slowly he began to rub her clit through the material of her skirt as Katya did her best to act normal. Fortunately they packed in like sardines and no one noticed their illicit movements.
Katya could feel Mark's cock growing harder and brushed the palm of her hand over his trousers. He responded with a light groan and pushed up against her thigh harder. Katya was becoming wetter and she was longing for the train ride to end so she could hurry home with Mark. As the journey wore on, more and more people got off until they were the last people in the carriage. Katya and Mark lived at the last stop on the line, and not many people who lived near them bothered to commute to the city. Mark glanced around and said,
"I think we're alone... with at least 20 minutes left of this journey..." Katya scanned the carriage and couldn't see anyone. But she still looked at Mark with a shocked expression,
