I love women with curves. Give me a woman with nice, round curves, a little padding, and a waspishly thin waist over a thin woman with hard edges and angles any day. Tall or short, big-boned or extra padded, those women just send my pulse chugging. That’s why I knew I was doomed the minute I saw Christie.
Every morning I travel by train to work. It’s typically 45 dull minutes reading or listening to music, twice a day. It always amazes me that by the third stop, the train is usually full, and by the fifth, it’s usually packed so tight that people are molded closer together than some concert mosh pits.
People manage to cram themselves in until you expect to hear it pop like a champagne cork when the doors open at the next stop as people spill out. Luckily, since my home stop is the last on the line, I typically get a spot to sit in the morning, and my work stop is past a major transfer point, so I can usually get one on the way back, too.
One morning I was heading into work a little later than usual. The last few weeks we’d been crashing a project and pulling late nights in order to hit the deadline. We finally rolled it out the night before, and I decided to sleep in late to recover. When I got on the train, it was already more full than usual, so I had to find a spot away from the area that I usually sit at and pulled open my book to read.
My eyes were pretty tired still from the late nights, so I was having a tough time staying focused on my reading. I found myself looking up and around at the people more than usual. It was at that point that I saw her standing about six feet away, leaning against the wall by the door, and reading a book.
I had no idea where or when she got on, but now that I saw her, I couldn’t take my eyes off of her. She was young -- early twenties -- and wore a rather conservative style for her age. Instead of the skin-tight skirts that ended above the knee and baby-doll tees that most women her age are wearing, she wore a white, silky blouse buttoned up close to her throat and a navy blue skirt that went past her knees.
I couldn’t help myself and started looking up from her feet. It was obvious that she walked a lot or exercised, and the heels made her calf muscles tighten into firm lines. She leaned against the wall slightly, so I could see the outline of her wide hips and generous curves of her ass against the skirt.
I followed those curves to an impossibly thin waist and then past the tucked-in blouse on up. It looked like she must have had large breasts, but her bra was confining them tightly. She had short, black hair, a round face, and large, blue eyes. As I was checking her out, the old lady that sat near her was looking at me. Our eyes met, and the old lady smirked. I was embarrassed that I got caught staring, so I looked away. But I couldn’t do that for long.
I kept stealing glances over at her, watching her read. Occasionally, she would shift her weight to a different foot, and I would watch her hips shift and imagine what it would be like watching her walk. Suddenly, she started to laugh at something in the book. She must have been surprised that she laughed out loud in the quiet train car and started to look around to see whether anyone noticed. And that’s when she saw me looking at her.
She looked rather surprised, and we stared for a while before she smiled and looked back at her book. For the next couple of stops, we played “eye tag.” She would try to look when she thought I wasn’t looking and glance away when she saw I was, and I would do the same to her. As the car filled, my view of her body was blocked, but I could still see her face. When we got to her stop, I watched how her hips twitched as she walked slowly off and then caught her looking back at me.
I spent the next three stops trying to get my hard-on to go down before I had to stand up. I was absolutely worthless at work that day and couldn’t get her out of my head. When I left that night, I tried to spot her but didn’t see her. For the next couple of days, I went in late but didn’t see her. I gave up and kept kicking myself for not talking to her or saying something.
Finally, a few days later, I saw her again. It was pretty crowded, and I had just given my seat up to a pregnant woman and was standing by the door when she walked on. She remembered me as well and stopped for a moment, smiling shyly before getting on the train and standing just to the other side of the door--about three feet from me. She was wearing a similar outfit as before: a conservative blouse and skirt with heels.
I couldn’t stay focused on my book and started glancing at her again. As the train filled up, we started getting pushed closer together. More people got on, and she was right next to me, turned sideways. She was blushing slightly and staring hard at her book. I was thinking, “Say something to her, you idiot! She’s right there,” when the door opened, and more people got on. She turned her back to me to allow more people to cram in and was pushed up right against me.
In her heels, she fit perfectly against me. Her ass was pressed against my hips, and her head was just under my chin. She was too short to hang on to the handrails on the ceiling, so she stood with her legs wide apart to brace herself. Her right hand propped up her book, while her left hand rested against the wall to stabilize. As the train moved, she started to bump against me.
I quickly got hard, and while I’m not Johnny Holmes, I know it would be noticeable in my pants if anyone looked or if she pressed against me. I tried to move my hips away so she wouldn’t feel it, but as more people got on and jammed behind me, she was pressed against me. I was horrified when she finally bumped her ass against me. She could feel it. She shifted her hips slightly as if double-checking what she felt and then glanced slightly over her shoulder, blushing. But then she looked like she had made a decision and slowly pressed back into me.
I almost came right there. My cock was just above the crack of her ass, and she was bumping into me as the train rocked. It was then that I noticed that she hadn’t turned a page in her book, and her eyes were closed. She was breathing faster. At the next stop, people got on and off, but she didn’t move.
When the train started moving, she leaned forward slightly and bumped her ass against my cock. I finally took a gamble and moved my right hand to her hip as if to steady her. She pushed her elbow down, clamping my hand against her waist, and started to grind back on me.
Unfortunately, the next stop was hers. When the doors opened, she quickly left the train, looking first at my face and then at my hard-on before smiling. I quickly covered myself, holding my jacket in front of me. When I got to work, I ran straight for the bathroom and jack off.
It was another couple of days before I saw her again. This time I had been standing in the hope of running into her again. I noticed that she stood in the door looking around a bit before she saw me standing against the wall by the door. Had she been waiting for me? She got on and smiled shyly at me, but came over to stand pretty close to me. As more people got on, she quickly shifted so her back was to me and pressed back. I let one hand fall and it landed against her hip. She didn’t complain and actually started to grind into me right away, so I started to slowly roam across her hips.
It was then that I felt she was wearing a garter belt. I stopped and almost came on the spot. I kept moving my hands around and couldn’t feel any panties underneath, only curves. She arched her neck and glanced back at me, blushing.
Suddenly she dropped her book and leaned over at the waist to pick it up. The back of her skirt rode up and I could see the tops of suspendered thigh-high stockings. That’s when I knew she had planned this -- wanted this -- and I started to get bolder. No one was looking.
Everyone was quietly in their own worlds and I doubted anyone could see anything below shoulder height in the press of bodies. I slowly started to grip her hips, grabbing where the garter belt was. She was leaning forward to increase the contact between us. When the train would rock, I would pull her harder against me. It was a slow-motion imitation of fucking.
When her stop came, she was rubbing hard against me and biting her lip. She looked at the open door and then at me. Her eyes were wild and she was as desperate as I was. So she pulled my hand and dragged me off the train.
She was pulling me along, not saying anything. I was staring at her gorgeous ass in front of me, and she would look back at me. When she noticed I was staring at her, she’d pull me along faster. That’s when I saw an alcove off to the side that led to a janitor’s door. It was dark and hidden. I pulled her to the side and waited until the crowd had left the area. Then I pulled her in there and pressed her hard against the wall. We started kissing frantically.
Her hand went straight to my cock and grabbed it. She was moaning into my mouth as she started to jack it off through my pants. I had one hand around her neck, pulling her lips to mine. The other hand reached down under her skirt and ran up her thigh to the juncture. I was right--she wasn’t wearing panties.
She gasped when I made contact with her pussy, but then started ramming her crotch hard against my exploring hand. I pulled my hand away for a moment, and she made a small grunt. But I wanted to release my cock out of its confines before I made a mess of my pants. When I took her hand, she looked up at me questioningly. I then unzipped my pants and fished my cock out into the open and put her hand back on it. She made little moaning sounds as she stared at it, jacking it off.
I had to have her and pressed her against the wall, pushing up her skirt. I grabbed her ass and pressed my cock against her bush, kissing and biting her lips lightly. She never stopped jacking my cock, and I was about to explode. But I wanted to cum inside of her, so I pulled her hand away and started to crouch down so my cock would line up. As soon as she felt my cock touch her wet lips, she grunted and started to push on my chest.
“Wait ... hold on ... stop!” She stopped kissing me. My eyes must have bugged out, and it took everything I had, but I stopped. “The first time should be special. I don’t want to remember it in this dirty hallway. Let’s go across the street.”
I knew there was a hotel across the street, so I quickly pulled myself together and she did the same. We were giggling like little kids as we walked out of the hall into more people getting off the train that just arrived and practically jogged across the street to the Hilton.
