Working the Daily Grind

Recently I've found myself doing something. The funny part is that I've BEEN doing it but I just caught myself. I'm a sales associate at a popular department store in a mall. During our shifts we have various 'chores' to do. I'm usually the one to dress the mannequins. I think nothing of it to sorta straddle a mannequin if I have to lay it down and put clothing on it. Another thing, my waist/crotch is about the level of the countertop. We have a counter that is low. I kinda press up against it if I'm standing there for a long time.

The mannequin thing was the one that got me. A co-worker commented that I looked like I was riding my lover. That's when it hit me that I've been bumping and grinding. Nothing obvious I don't think, just slow and submissive. I've discovered myself that if there is some sort of object around, my crotch finds a way to press up against it for about 10 seconds of pleasure. I haven't orgasmed from it but I do get a slight arousal. I've been told that my face looks flushed at times and I've noticed my nipples erect. When I was a little girl I used to grind on my stuffed animals. Maybe this is a subliminal continuation?
