You lead me to the lower carriage of the train and sit down on one of the backwards-facing chairs that has the four chairs facing each other. This was a surprise to me as I knew you were going to play with me, and I did not see how this was going to be subtle...
You pulled me to stand close between your legs. My skirt comes to just below your legs. I feel your hand under my skirt but you don't touch me; you grab my waist spinning me saying, "You can sit on my lap, Slut, to save on seats."
You pull me down into your lap and directly onto your cock. This surprises me as you have never fucked me somewhere so public before. I inhale sharply, and gasp as you pull me straight down, forcing your cock up into me; squeezing my waist and whispering, "Don't make a sound, or they will all know you are a slut."
I swallow hard...
You ask me out loud, "Comfy there?" as you pull me backwards to lean against you. My legs raise as I'm startled, which allows you to close your legs under me with ease. As I become calm, and my legs relax, they hang on the outside of your thighs and my feet can't touch the ground.
"Yes," I reply, a little breathless, as my weight bears me down on to you.
The train moves, and I startle again as I realise I have no way to counter the movements of the train with my feet in the air. I instinctively go to grab you, but you whisper, "No, relax your hands and enjoy the movements."
You feel more than hear me whimper, and I feel you chuckle a little in return. We sit for a few stops with you slightly holding my waist and tightening when required for balance, but at near each move the train makes I clench around you and I feel you throb in return.
I watch out the window, but from the corner of my eye notice when people sit opposite us. I try to relax into you and appear calm, even though I know you can feel me tense more just because someone is so close. I can feel that I'm dripping wet and know that you can feel it running down over you.
