One time I was alone in the ladies' room where I work and the light was off. There is a window so I had enough light so I didn't bother to turn the light on. I was in the end stall. A woman came in and used another stall and must have thought the place was empty because I heard her pee but then she didn't get up, and I was wondering what she was doing in there. I found out soon--squishy sounds and fast breathing and then a long moan while she came. This was very exciting. I waited until she left and then I did what she'd just done.
I work for a company that has 200 women on the phone all day. They are supposed to use the ladies' room during scheduled breaks but if someone really has to go, she can. I'm in IT and I have a looser schedule so I can go in there whenever I want. If I go in there between breaks there usually won't be anyone there, but someone comes in every now and then. After that wonderful moment I started spending long periods in there hoping that it would happen again. I would resting my feet on the inside of the door of the stall so that it would look like no one was in my stall, if someone bothered to look under the door, even though it was shut. For four days the people who came in just used the toilets for what they are supposed to be used for but finally someone came in to masturbate. I knew what she was doing when I heard the squishy noises. This time I decided to come along with her. I pushed my pants and panties down to my ankles very quietly---my feet were still pressed against the door and took them off one leg so that I could spread my legs wide. Then I rubbed softly and quietly around and sometimes over my clit. I tried to keep my breathing quiet. As she built up I thought I could relax a little since she wouldn't be listening hard. This one was noisier than the other one. She took kind of a long time to come and I finished first---it was so exciting and naughty. After she came she still didn't get up. Then I heard her breathing get short again and she came again. That one didn't take so long. Then she waited only a few seconds before starting up again. I was still excited and came a second time myself. Her third orgasm was really loud and she sat there panting for minutes afterward. Finally she got up and I heard her clothes rustling and she left. I went back five times over the next two days but no luck. I know I should stop doing this but this is just about the most exciting thing in my life right now and I think about it before I come to work and all day after. It doesn't help that I spend a lot of my time in my office there reading this site or looking at dirty pictures on the net.
