The thrill of jacking over the urinal
One day I was in the restroom at work pissing in the urinal and I noticed that the chest-high partition that is placed between the urinal and the sinks (and door) was all that was between the urinal and the door. I had availed myself of the toilet stalls on more than one occasion to jack off when the urge was too hard to resist, but this was different. What if I were to jack off in the urinal where anyone that came in would see nearly my entire body except the waist hidden behind the partition.
The thought wouldn't go away and one day the little man was pestering me to take him out and play. I went into the restroom with the intention I would just see again if it was possible. It was and on the spot I decided to try it out.
The restroom is shared by about 25 men and any one of them could walk in at any minute, but that was the fun of it. I pulled up in front of the urinal and started jacking. It was enormously exciting and it was only a handful of strokes before I was fully hard. I didn't want to tempt fate too much and drag it out mainly for fear that I would have to stop jacking if someone came in.
The excitement was tremendous and a minute or two later I was shooting ropy streams into the urinal and if someone were to stop in then, they would see a happy, serene face and hear a few light grunts. I then wrung out the remainder and went back to my desk, the automatic flush took care of the evidence.
Funny thing is, I tried it again today. There was little risk as most people were out on holiday, but it was fun nonetheless.
