Andi skipped ahead of me to get on the train. Wherever her body went, my eyes just seemed to follow: the legs, the butt, the boobs, the face. They were all like a drug to me, I just couldn’t get enough. I didn’t know how I was going to survive the next three hours on the train being next to her but not be able to “have” her. Andi turned around, flicking her fire red hair in my direction, as she reached the steps of the train and smiled back at me. I just looked at those lips of hers and remembered they had been locked around my cock only an hour ago,  those brown eyes staring up at me as I pumped her mouth full of cum.

“C’mon” she shouted at me and, purposefully wiggled her tits at me. It was one of the things that I had first noticed about Andi (and to be quite frank still find awesome) - her boobs. She was a deliciously curvy creature, but those 34F’s of hers were to die for. I’d spent many a happy morning, afternoon, evening (well any time I could get) with those boobs. Now they were off limits for at least the train journey. I don’t know if she had chosen her attire on purpose to tease me (or perhaps other passengers as well). She was wearing a summer dress which wrapped around her boobs with a plunging V line to highlight her cleavage, the bottom of the dress just resting above her knees; flowing but thin fabric which if the light was shining in the right direction would leave little to the imagination. I knew she wasn’t wearing a bra under the dress and just knew I was going to be teased and turned on by the sight of her tits for the whole journey.

I got on the train behind Andi and gave her bum a playful grope. She pushed back against my roving hand as I slipped it under her dress and reached around to give her pussy a touch. I heard her give a little groan and then she moved back into the train. I followed behind her with my cock growing in my pants. Thankfully we were still in an empty carriage, so found some empty seats with a table. Andi sat by the window and I took the aisle seat. I turned around to her and asked

“Well, are you going to help me out here or am I going to be left in agony?” while grabbing hold of now erect cock.

Grinning at me she said “I thought I’d taken care of that earlier?” but used her hand to remove mine and start massaging me through my jeans.

I looked quickly around the train and saw that it was still empty, so quickly popped the buttons on my jeans and my cock popped out.

Andi let out a laugh, “I can’t believe you!” but she soon dipped her head and started to lick the top of my dick, feeling her tongue twirling around my helmet. She was an absolute killer cock-sucker and always seemed to know what I loved. Her lips pushed themselves over the head of my cock and I could feel her tongue going to work on the underside. I groaned in lust, but at the same time heard a noise from the other end of the carriage. I tapped Andi on the head and pushed my cock back into my jeans as a couple lurched into the train with their luggage. I wasn’t sure if that little lick actually helped at all or just made things worse for me!

The train started to fill up and Andi spent the time just teasing me further. Pushing her finger into her mouth and seductively sucking it, grasping her tits and running a finger over a nipple when no one was looking. Anything she could think of to make my cock feel trapped and uncomfortable, wanting to be free and taste the delights of her mouth, hand or body! All too soon the train had filled up and was on it’s way.

Andi was staring out the window while I was trying to distract myself with a book I’d bought. We  were just pulling away from the first station when she turned to me and said, “I’ve got an idea, come with me.”

I wasn’t going to argue, thinking we were probably going to start some daytime drinking or something, so hopped out of my seat and followed Andi down the carriage. We went out of our carriage and passed down into next. I was trying to think if I wanted to have a beer or just crack on with the wine when I got pulled to the side. I’d been walking in a bit of a daydream and didn’t notice we had come across one of the large toilets on the train. The door was shut and locked behind and Andi was grinning at me.

“I’m sorry for teasing you. It was just so much fun to see your frustration rise along with your dick. I thought it wasn’t fair though, so here we are to help fix that!”

She immediately dropped down to her knees and started opening up my belt and jeans. I couldn’t believe my luck, I had been thinking I was going to be stuck on the train with blue balls and now she had my dick in her mouth.

Andi picked up where she had left off earlier, easing her lips around the head of my cock and letting her tongue swirl around. Her hand went to my balls as she started to massage them in time to the movement of her tongue. She was soon slurping up and down my length, licking the underside of my shaft as she move around it.

My cock seemed to be getting harder and harder under her attention as she stopped to look at the my cock while wanking it, before spitting on the head and continuing to stroke it. She then moved her mouth over the tip of of cock before moving it up and down in time with the hand moving over my shaft. She began to build up speed over my cock and began twisting her hand around my cock on each upward stroke in combination with swirling her tongue of the top of my cock at the end of the stroke. I was soon in heaven and moaning in response. I open my eyes to see that Andi had moved her knickers to the side and was stroking her pussy in time to my cock.

“Enough, I need it inside me,” she breathed. She stood up and was just about to guide her cock inside me when there was a banging on the door.

“Is there anyone in there? The door is locked but it’s been quite some time. I REALLY need to go. Urgently.”

“Not. NOW.” I managed to grunt as the head of my cock eased apart Andi’s pussy lips.

This just encouraged the person to try again with more banging on the door “Please open up now. I. Need. The. Toilet.”

Andi just looked at me and backed away, leaving me standing there with my cock pointing to the sky and my jeans around my ankles.

“This isn’t going to work is it,” she said.

I just groaned in frustration and picked up my pants and jeans as I tried to stick my stiff cock within them. We unlocked the door and let it swing open to find a man standing there with his legs crossed and sweating. He looked at us and then realisation seemed to dawn on him as he looked down in embarrassment. We shuffled past and just made our way back to our seats. So close and yet so far.

I settled myself back into the seat and just glared at my book. I think I would have just preferred to have just sat here the whole journey and not have been worked up like this. I’m sure Andi must have been feeling the same, she was just getting ready to ride me and it was rudely interrupted. I felt her hand seek out my hand that was laying in my lap. Well, any physical contact was better than none.

I moved to put my hand in hers but she pulled both mine and her hand away towards herself. I looked over to see what she was doing and then saw where she was taking my hand. She moved it underneath her dress and pressed it against her pussy, her uncovered pussy. Andi hadn’t put her knickers back on before we left the toilet, and now I could feel how wet she’d become.

I looked up at Andi to see that she was just staring nonchalantly out of the window but gently moved her pussy against my hand. I took the hint and traced my fingers across her lips.

Taking a cue from Andi, I pretended to read the book in front of me as my fingers went to work. I kept moving my fingers up and down her pussy, getting them slick with her juices, every now and then pausing to flick the tips of my fingers across her clit. With each flick I could feel a shudder go through Andi, not enough for anyone else to notice but I knew.

I scanned around the carriage to see if anyone knew what we were up to; people were reading books, listening to music staring into space, working on their laptops, looking at their phones. No one was paying us any attention, but I was making sure Andi’s pussy was getting plenty of attention.

In combination with irregular flicks of her clit, every now and then I would work a couple of fingers inside her and pump them in and out. Just a short, slow movement of my fingers inside her. Curling them up to stroke the roof of her, seeking out that rough little patch of her g-spot. Andi’s shudders we’re getting more frequent but what was impressive was the lack of noise; she’s normally quite vocal and good at issuing direction and encouragement. However, she was silent and her face was fixated on what was outside the window, though I doubt she could have told you what was out there. Her whole mind was focused on her pussy and my fingers.

I started to pick up the pace a little bit as my fingers moved back to her clit. Circling around and around with the occasional swirl across, slowly building up speed as her clit become engorged in tandem. I wish I could have used my other hand on her, but I had to keep up appearances.

So I went back to pushing my fingers inside her and began to pump them in and out, feeling Andi’s hips move in time. She started to try and hump my fingers as the feeling began to build up inside her. I could hear small squelching sounds coming from underneath the table as my fingers were getting more and more frenzied. When I could feel Andi getting closer and closer and moved back to her clit and started rubbing and caressing it as if my life depended on it. I could feel her moving in time to my fingers, yet still not a sound had escaped her mouth.

I moved to the tips of my fingers and begin to circle away at her clit to try and bring her over the edge when suddenly her legs clamped shut on my hand and locked it in place. I could feel Andi shaking in the seat next to me and her breathing was coming in short sharp intakes. He head was down and her beautiful red hair was cascading over the table. We sat like this for about 30 seconds before Andi began to move her legs apart and release my hand.

I moved my hand away from underneath her skirt and looked back around the carriage to check our privacy had been maintained. If anyone had noticed or been watching they were doing a good impression of not caring. I look back to Andi and noticed that her boobs were still shaking slightly and her face was flush.

She just grinned that beautiful grin and me and said “Thank you” before planting a kiss on my cheeks. “Now, if you’ll excuse me I need to go freshen up.”

I was still being plagued by a massive erection but managed to shuffle myself half crouching out of my seat and into the aisle so Andi could get past. She went back dow to the toilet while I sat back down again and contemplated going to the toilet after her and having a wank to relieve some of the frustration.

Still, I couldn’t quite believe I’d just brought my girlfriend to orgasm on a packed train and nobody seemed to have noticed. As recompense, I slowly sucked the fingers of my hand so I could taste the juices that had come from her pussy. I was going to suggest that Andi only ever travelled in a dress from now in as I think I had just found my new fun travel activity.

It wasn’t long before Andi come back but instead of waiting for me to get up she bent down and whispered in my ear “Follow me now.”

I wasn’t sure what was going on, yet again, but found myself following her down the train again. This time we went past the toilet and started to find the number of passengers thinning out, until we came to section where instead of seats in rows there was bench seating. Andi pushed me down on the seat and then sat on my lap facing away from me.

I was about to say something when she started talking: “I’ve been having fun on his train. I’ve enjoyed sucking your cock. I’ve enjoyed you fingering me just now. However, what I’ve been needing since I woke up this morning is for your cock to be deep inside of me. I thought we were going to fuck in the toilet, but that was killed. I can’t really have you slipping me your length as we are sat in our seats back there. However, here there isn’t really anyone and I can sit on your lap quite easily.”

As she said this she started squirming on top of my cock.

“So what we are going to do is, you will fuck me here. My dress is long enough that nobody can see anything when I’m sitting on you and nobody is really around to notice what we are doing anyway. What I need to you do to get that beautiful cock of yours out of your pants and put in in my pussy. I’ll do the rest.”

I couldn’t believe my ears and quickly fumbled underneath her dress to unbutton myself and release my cock. Once it was out it was lodged against her ass cheeks and to be honest I could have just worked it up and down between them and cummed  fairly easily. However Andi had said she wanted, no sorry, needed my cock inside her, it wouldn’t do to disappoint her. So I held my cock as Andi lifted herself off my lap slightly, allowing me to push it forward and find her pussy lips. I let my cock rub gently against the outside a few times before I pushed the tip inside her.

Andi stayed like that for a moment, relishing the feeling of my cock as it was just beginning to open her up. Then slowly, imperceptibly, she started to push down on top of my cock as I held her hips as if to guide her. Slowly, slowly she began to engulf every inch of me until she was sat down on my lap again. However this time she had my cock deep inside of her. She just sighed in enjoyment and sat there feeling her pussy beginning to accommodate my dick inside of it.

We both looked around again and couldn’t see anyone near us, so Andi started to gently rock backwards and forwards on my lap in time to the train vibrations. I was just focusing on keeping my cock inside her and not cumming too soon.

While she was doing this my hands began to wander away from her hips and began to reach up to her tits. I have always enjoyed tweaking her nipples whenever she rode me cowgirl, so my natural instinct took over as my hands roved over her chest.

A sound down the corridor made us sit still and upright. A passenger was making his way down the train and towards us. I felt Andi start to flex her pussy muscles around my cock as we both watched the person getting closer and closer to us. Was he going to notice, was it actually noticeable? If anything, Andi’s flush face and erect nipples should have been a giveaway. However he just stumbled past without saying a word or even acknowledging us.

We both breathed a sigh of relief that we hadn’t been observed, only to draw that breath back in when we heard, “Tickets please.”

My heart reached into my mouth, only to feel Andi grind down on my cock. I didn’t know what to do. Should I just sit here, should I push her off and button myself up? I was procrastinating for far too long as pretty soon the train conductor had come to where we were sitting. I was like a rabbit in headlights, but Andi was just taking it all in her stride, as well as her pussy.

“Morning!” she cheerfully trilled to the conductor, at the same time as she was squeezing her pussy around my cock. “Tickets are just in my purse if you can wait a moment?”

“Of course,” the conductor replied and then proceeded to sit down opposite us. He then started to make small talk as Andi started to reach down to her purse that was on the floor beside us. I could feel her pussy moving along the length of my cock as she bent down further and further, half expecting it to pop out at any moment. Before that happened I could feel her start to push back along my cock as she sat back down on my lap.

Andi started delving around in her purse, all the while grinding away on my cock. To me she was making quite obvious movements back and forth, seeming to enjoy fucking me right in front of a completely oblivious person. This time around it was my turn at having to avoid making any obvious noises as she rode me. Thankfully, she found our tickets and handed them over to the conductor. He stamped them and handed them back, replying, “Enjoy your ride.”

I was still trying to figure out if he was actually aware of what we were doing, when he disappeared down the train looking for more tickets.

Thankfully, my mind was quickly diverted to what my cock was doing as Andi soon found her rhythm again. This time she was starting to rise and fall in my lap, working on my cock, plunging it deeper a deeper inside herself. After everything that had been going on I could feel my own orgasm beginning to rise. My cock was getting harder and I could feel my balls beginning to tighten.

I whispered to Andi “I’m going to cum!”

All I got back by way of reply was, “Not yet. Not yet.”

I could feel her trying to increase the speed of her movement and she was getting bolder and bolder with the rising up and down on my lap.

She slammed herself up and down in my lap a couple more times before grunting through clenched teeth, “Yeeeesssss”.

I could feel her pussy muscles tighten around my cock, which just seem to set off a chain reaction. My cock started spurting deep into her pussy. I felt myself convulse three, four, then five times as my balls finally emptied and Andi’s pussy milked them for all they were worth.

She remained sat on my lap while my cock began to soften. She turned her face around to kiss me and said, “We should take the train more often.”
