I live in a Chicago suburb and take the Metra from school back and forth to my home every day. A few weeks ago our English professor assigned us to see an evening lecture on campus which is on the north side of town. The guest lecture ended and I kind of had to pee but I knew that if I did I would miss my train. Even though I had consumed way too much coffee I ran directly to the Metra station which is right on our campus and hopped on. My commute home involves riding downtown and transferring to another train that goes to the western burbs.
Assuming that I could pee at the station before I transferred I sat uncomfortably on the train. Unfortunately we were delyed and by the time I arrived at my transfer point I only had a few minutes to run to my next train. I decided that I could hold out and changed to the next train.
After just a few stops I knew that I had made a huge mistake. The pressure in my bladder was growing and I was not going to make it. I moved to a seat where no one would be able to see and then used a trick from childhood. I pressed the heel of my hand into my crotch and applied pressure. The urge to pee was relieved but I knew that I could not hold on for too long like this. Two stops later, I unbuttoned the waist of my jeans and discreetly slid my hand inside my pants to increase the pressure. That seemed to be working for a few moments but then the feeling of arousal stated to overwhelm the urge to pee.
The vibrations form the train seemed to be following my legs directly into my vagina and by pressing against myself with my hand I was transmitting these sensations right into myself. It was the most aroused I had ever been and as I moved my fingers discreetly down and against my clitoris I made the feelings even more intense. I didn't have to move my fingers like I usually would if I was pleasuring myself, just let my hand and my fingers rest in the appropriate places.
Soon I was lost in the fog of pleasure with feelings of arousal radiating from my secret little spot to my tummy and my thighs. The feelings were unbelievable and I was lost in them until suddenly two stops from my final destination I had the most amazing orgasm. I had to fight not to convulse and moan out loud and alert the other people on the train as to what I was doing.
The last contractions of my climax had not ended when the urgency to pee returned but this time it was far too powerful to resist. I tried pressing with my hand again, but the result was a gusher of warm urine that suddenly spread through my panties and began to soak the crotch of my jeans. I pressed with my hand again trying to stop the stream of urine and as I did I had another climax. This was the first time that I had ever had more than one orgasm and the feelings were unbelievable.
I finally gave up and let myself empty. As I sat there urine ran down my legs and began to stream onto the floor of the train and that was when people began to notice what I was doing. There I was, approaching my own train stop with soaked jeans, my hand inside my pants and pee running onto the floor.
I hurried to my car in the parking lot and drove away after the train arrived hoping that no one had recognized me. In my driveway at home before I hurried inside to change clothing, I fingered myself to a third climax.
