I fumble in my pockets to get the tickets to get through the turnstile, as we can hear a tube train arriving.
We've met up in London for the day and have had a couple of drinks or three and are trying to get across town to take you home.
'Come on, come on, we're going to miss it!' and you press up behind me and start going through my pockets.
'That's not helping!' as I squirm against your inquisitive fingers, 'Ta-da! Here they are! Come on then.'
We race down the steps and onto the platform, as the hiss of the doors starts, 'Hang on!' I shout and an obliging soul does and the door is held open for us to fall through.
'Phew! That was close and we've still got another tube before we get back! But at least there are some seats.' With that I fall into one and you take one directly opposite me, leaning back into it with your knees slightly apart.
The carriage is almost empty. Our saviour has got off at the next stop and everyone else is at the other end of the carriage - two other couples, one in their fifties and discussing some musical they've seen and the other an Asian looking couple who look like students.
'Awww, what'd you have to sit over there for? Come over here so I don't have to shout across at you.' And I patted the seat next to me and beckoned you over.
'Nope, I've got comfy and who says I want to talk?' And you rest your hands on your thighs just above your knees.
I sat back in my seat, 'OK, be like that then!' And I turned my face away to people watch the other passengers. The initial excitement of fumbling in my trousers starting to subside now as I thought about our next connection and the time we had left to get the train.
'Just because we're not talking, it doesn't mean that I shouldn't have your attention'. As I turned to face you again, I saw that your legs had moved further apart. Now you lowered yourself further into your seat so as to give me a view to the shadows that caressed your upper thighs below the edge of your skirt.
Your left hand was still on your thigh and rubbing the material of your knee length dark skirt, causing it to gather and crease. At the same time, your right hand was under your jacket and tracing the outline of your breasts.
'You have my complete attention. Talking of which, there's definite evidence of standing to attention down below!' And I cast my eyes down at the bulge in my trousers and copied your posture by pushing my legs out toward the centre and leaning back in the seat.
'Good, I was trying to feel him earlier at the ticket barrier. I'm feeling really naughty tonight. I wanted to take you into the toilets with me at the last bar but it was too busy! So instead, I had a little rub to get rid of the frustration!' At that you looked me straight in the eyes.
'O Honey, you are so sexy. Why didn't you say? The gents was empty and I had a big stiffy for you. Did you come?' As I spoke I adjusted my trousers to allow the swelling beneath to move around more freely.
'Mmm, big style. My thong got so wet, I had to take it off!' With that, you reached into your bag. 'Here, catch!' And you threw something over to me and when I looked in my lap, I saw your sexy black thong resting on top of my twitching trousers.
