I’m a trainer at a bank (I won’t mention which one in case one of you work out who I am) and yesterday was the last day of a two day session I was holding on the new e-mail and internet rules. I always like to dress very smart for work and yesterday I was wearing a suit which has a pencil skirt. The skirt isn’t particularly short (a couple of inches above my knee) but it is made of very thin fabric and is very tight. As usual, I didn’t wear knickers with it, just tights. Well this morning I managed to badly ladder my tights on the way to the training room. Usually, I have a spare pair with me, but yesterday I didn’t. As I couldn’t stand in front of everyone with holes in my tights and there was no time for me to go and buy a new pair, I had no option but to take them off. So I ended up delivering my training sessions to about 200 people in 6 separate groups wearing a very tight skirt and no knickers. Obviously I didn’t tell anyone, but I felt very self-conscious about it and I just couldn’t get the thought of it out of my head. All through the first session I couldn’t stop thinking about that fact that I had no knickers on and I became fixated on it and couldn’t help wonder if anyone could tell. By the end of the first session, I was feeling massively horny and had become very wet. I didn’t want to sit down because I was really worried that I would end up staining my skirt and then everyone would defiantly have guessed my state of undress. This meant that I was constantly standing up right in front of everyone. So during the break I just had to go to the loo and relieve some of the tension I was feeling. I locked myself in the cubicle and waited for the place to become empty before I hitched my skirt up; which was a major feat in itself because the skirt is so tight. I then, opening my legs slightly, started to rub myself until I had a wonderful orgasm. Because I was so worked up it took me no longer than a few seconds and was such a deep, powerful orgasm I had to stand for a few minutes while I calmed down a little. My fanny was still feeling very twitchy and sensitive and I could hardly touch it without setting myself off again. I thought that there was no way I could go back in this state so I decided to bring myself off again. This time I came just as quickly and the orgasm was even more powerful than the first. My legs were shaking and I was finding it very difficult to keep quiet. Then, just as I’m getting to the climax of my third orgasm, the door opened and at least 2 people came in to the toilets and entered the cubicles either side of me. I was frozen with a combination of fear and excitement. There I was in work with my skirt hoisted up round my waist with no knickers on masturbating like fury and right on the point of what was making for an amazingly strong orgasm. I just couldn’t stop and pummelled myself to third and most leg trembling orgasm I’d ever had. I can’t believe that I was silent and I’m sure that the girls on either side (whoever they were) must have heard something from me. I’m convinced that they’d have been able to at least hear my heavy breathing. After waiting until they’d left the toilet, I sorted my skirt out and collected myself together before going back to the training room. Still commando in my tight skirt I was still a little preoccupied by it but at least I was feeling less frustrated by being without knickers. What a day it was!
