It might have been the train, or perhaps her sheer boredom riding the Red Line all the way out to Shady Grove. Close in to DC the stops came up quite often and she must have spent her idle time watching the passengers entering and exiting the train. After Tinleytown and Friendship Heights, the stops began to stretch out as the train ran the rail toward and then into Maryland. I was sitting at the back of the car, tucked in behind a small partition, but even though could see around it I didn't notice her right away. I had been riding about twenty minutes before I noticed her sitting in a seat facing my direction.
She wasn't what I'd call pretty, not ugly, a bit attractive, but not anyone I normally might notice on the street. I wouldn't have noticed her at all if it weren't for the way she was looking about the car, fidgeting as she looked. Obviously distracted by something, I noticed her noticed the different men in the car, looking them over from top to bottom, pausing uncomfortably long at their crotch and then glancing off to another man. If she did appear to make eye contact, she'd seductively toss her long black hair over her shoulder and then lean forward, as if to check her shoe, giving the man an excellent opportunity to look down her overcoat.
This continued over the next few stops as her prospects slowly disappeared off the train, obviously curious about the woman, but also caught up in their daily lives. With only three stops left before the end of the line, most of the people had exited the train leaving only her, another lady and myself. She hadn't noticed me before, but as soon as she did, I watched her black hair cascade back over her shoulder and then took advantage of the view she gave me, rubbing her hand over her boot.
When the train screeched to a stop and the other lady stepped off the car, and no one else got back on I watched her spring to life. As the doors closed and the train started moving, she immediately stood up, and carefully sliding her hand on the handrails overhead, she walked back to me. Without speaking a word, she stood facing me, her hands slowly unbuttoning her coat buttons, one after the other.
Pausing for a moment, she looked into my eyes and said, "What stop are you going to?"
"Ah... ugh, Shady Grove," I replied nervously.
"Okay, there's time then," she said, opening her coat. All she had on under the coat was a garter belt and some dark hose and I found myself staring at her erect nipples. Noticing me stare at the nipples she said, "Yes, I've been cold all day, and they've been just like that, in dire need of attention."
I quickly reached up to my belt and unfastened it, unzipped my pants and pulled them and my underwear down to my ankles. Smiling at my erection, she moved in front of me and while leaning her back on the partition, she put her knees on each side of me. All I could do is watch in fascination as she slowly lowered herself down onto my cock. She was very wet, so it slid in easily quickly moving deep into her pussy. I moved my hands to her breasts, and though they were small, I let my fingers play over her hard nipples as she arched her back, resting her head on the partition as she moved herself up and down.
