Fun at work

I used to work security in a warehouse years ago. One particular evening I dropped off something in this girl's cubicle. As I turned to leave I see this plastic rain jacket hanging from a hook. It was what they called a "jelly jacket" that had pinstripes in a few colors but was predominantly clear. I went back to the lobby, closed the blinds, made sure the door was locked and went back to the cube. I was expecting a visit from one of the supervisors so I didn't want to be surprised. It felt so soft. With shaking hands I tried the jacket on. It was a little small on me but it fit. I went into the restroom and checked myself out in the mirror. For the first time I was able to wear something I'd only dreamt about. I knew I didn't have much time but when would an opportunity like this present itself again? I pretended I was a sexy girl teasing some guy. I posed, winked and teased myself in the mirror until I couldn't take it anymore. I went to the urinal and spanked it. After I finished I put the jacket back on the hook and ten minutes later I was talking to the supervisor as if nothing happened.
