So I was running late for work and grabbed some wind breaker pants, a t-shirt and ran towards the train station. As I was running up the stairs I can hear the train rumbling towards the station. I fumble my metro-card but managed to swipe and get by the turnstile. I thread my way pass the doors and find my way in a crowded train. As the train moves along to the next station, I noticed that there were more people waiting on the platform than usual. Upon slowing down a voice crawled over the P.A system about an accident on the following stop. The train pulls up and the people waiting on the platform force their way in. As the pushed in I bumped a woman in front of me and apologized for that and blamed it on the crowd. She said no problem and turned around. Upon turning around her ass grazed my hand and she looked over her shoulder quickly and faced front. I immediately noticed this and raised my hand to my chest so she can see it wasn’t on purpose. Soooo if anyone has ever been on a train, you wound know about the side to side motion it creates while moving. Her ass pressed up on my hip and I could feel the silky dress material through my wind breakers. This gave me an instant hard on. This all happened before the train even reached its first stop. So when the train stopped her ass slide across my hard on. She gave the save little gesture she gave before and face forward, only this time her ass crack was lined up with my throbbing cock head. So I stuck my ass back, so she won’t feel it but people were pushing there way in. I apologized again but she ignored me this time and just stared forward. By this time she can definitely feel my hard on that’s pressed up on her left butt cheek. The train takes off and she slides across my hard on again but this time I went across her whole ass. I mean left to crack to right cheek. She managed to stop herself in mid stride but it happened to be right on her crack. It was like my cock had a mind of its own it went straight in her crack I said nothing and held on to the nearest pole ass to show her it wasn’t my hand. The continues its side to side motions and by this time I’m practically dry humping her. The train stops again the people shift around but she manages to stay in front of me but not pressed up. The train takes off again and she grazes that nice soft ass across my cock again but by this time she stop exactly on my cock. I pushed up a bit and I’m not sure but I think she spread her legs a bit to let me in. This time I was ready, I adjusted my cock through the boxer hole so the only thing separating us was her silk dress and my wind breaker pants. Again we continued the train motion dry hump for the next couple stops. Every stop it got more intense. I know she could feel the mushroom head squeezing through those cheeks, only for her to move from side to side to let me in a little deeper. As for me I would thrust with the train’s sway so as not to draw attention. But alas all good things come to an end because the next stop is on of those stop we’re everyone gets off (lol). The train stops and everyone scrabbles, she turns around and I apologized, she said it’s ok with a fresh little smirk and runs off. I adjust my hard on and try to chase after but she lost me in the crowd.
