The train rattled and jolted through a junction, the same as it always did. The girl held tight to the nice soft boobies in her hands, almost pulling the older woman off balance. It was exciting, holding this not unattractive woman like this, making her excited, forcing her to live, rather than just exist in the dull grey world that everyone else on the train inhabited. She felt the need to turn the woman around, but... But that would break the spell. No. Anonymity was key, knowing that the woman was pretending it wasn't happening just the same as everyone else on the train, those who were standing facing them, had pretended not to notice. The woman was pressing against her now, moving her hips, rubbing her buttocks against the redhead's belly. A quick glance out of the window by twisting her head around showed that there were only a few more minutes before the train slowed into the terminus. She'd travelled this route often enough to know more or less where they were. She began kissing the back of the grey lady's neck, alternating between soft, tender pecks and hard sucking or biting.<i>I'm marking you as mine!<br/>
</i><br/>As the train began to slow and rattle through the switches outside the station that would determine which platform it stopped at - always the same one, she released the woman's right breast, her hand travelling slowly and deliberately down the front of her captive. She timed it perfectly, dipping a finger into the belly button through a gap between two buttons on the front of the blouse. She felt the reaction and resisted the urg to giggle as she withdrew her finger. Her hand continued its progress down, even as the back part of the platform slid into view outside the window and the train's air brakes hissed.<br/><br/>She slid her hand past the woman's waistband, feeling the grey material of the slacks under her palm. She wanted her hand inside them, but didn't dare. But what she did dare was, just as the train slid to a halt, to cup her right hand over the woman's crotch, giving a nice firm squeeze. As she did so, she bit again, on the same spot as yesterday. The previous bites had just been playful nips with her teeth, compared to this. This time she left a very clear indentation from her teeth.<br/><br/>"Tomorrow..." She whispered the word in the woman's left ear, as the door behind her opened, and she was gone. Vanishing into the crowd, a brief flash of colour dancing away in a sea of grey, a single clownfish in a shoal of grey mullet.
