Despite her silent protests, her efforts to stop him were futile. She resigned herself to clutching desperately at his wrists while he did as he wished and hoping desperately for her stop to arrive. When the train pulled into the next platform she seized the opportunity to get away when a group of passengers exited. She couldn't get off but with any luck she could find a spot further away, but unbelievably the space was replaced almost immediately by more people, as ignorant and unhelpful as the last. Regardless of her best efforts she was pushed back towards him, the cramped space in the carriage suddenly more oppressive than ever.
He had really only been toying with her before, but as the stations between hers ticked steadily away, her resistance crumbled. It was impossible to defend all possible fronts, for when his fingers had found the slight parting of her thighs where they have way to her buttocks, and forced themselves between her tightly clamped legs, her reflex at pushing away his arms left her front completely unguarded. In an instant he adapted to the situation, whipping his arms round her and grasping roughly at the soft mound between her legs. Once more she grabbed his wrists but his fingers clawed at her, an index digging beneath the elastic of her underwear, the nail pinching her clit painfully.
When she finally succeeding in dragging his hands from her pants, he merely forced her against the vertical handhold and ground himself against her.
Then she felt it. Somehow, at some point, he must have taken 'it' out, for she felt it's heavy weight almost 'thwack' against the back of her thigh, and hold there, hard against her. She felt too how, when first slapping against her, a strange sensation was left on her skin, that now it cooled she understood to be a wet 'something'.
All of a sudden, the cry of some completely unknown emotions, that which had built in her for so long burst from her in a startling 'nnnuuhnn' sound, which wasn't completely covered by the bell of the doors opening at her station. As people immediately made for the door, glancing back with minimal interest at the strange girl who just screamed 'nnnuuhnn', she tugged to be free and suddenly found that he was no longer holding her. Not caring to look back to see if he had casually assumed a vacant expression like the rest of the passengers, nor even considering to turn and scream her accusations, she tore from the carriage, not caring about the disgruntled cries from the people she had barged.
