It was exciting. Why was she doing this? Because the woman in grey with the greying hair was tired of living, and no one should be tired of living. Life is too short and it's all we have, so to want it to end... That was just criminal. And so the young redhead in the loud unmissable outfit was punishing the older woman for being miserable. She wanted the woman to suffer, to be torn between the embarrassment of causing a scene by doing something about it, and the humiliation of allowing her to continue. The woman chose humiliation as the train rocked and swayed its way into the city. The redhead was turning herself on. She wanted to go further, but... she was worried about breaking the spell she had the older woman under. Hubris and lust warred with caution and the desire to keep doing what she was already doing - the woman had tacitly consented to this by not objecting, not stopping her.<i>You could have turned around and said 'No' at any time... You haven't.</i>So she kept doing it, pressing her mound hard against the soft buttocks, rubbing up and down, side to side, feeling the heat and wetness between her thighs.<br/><br/>Her nipples poked hard through the cloth of her bra and shirt, and she rubbed them against the grey woman's back. And then they were slowing into the terminus. A journey over too soon, but a journey not wasted as so many were. She had brought herself some pleasure and hopefully brought some excitement into the woman's dull life. The train stopped and just before the doors opened, she released the woman's hips, lifted the grey-blonde hair from the back of the neck and pressed her lips to it, then her teeth, firm but not hard, she bit, to leave a noticeable mark that she dropped the hair back over, turned and skipped out of the door to vanish into the crowd heading for the exit.
