I haven't been to the gym all week. A full week without the gym, and I get a whole lot of excess energy. Throw in the fact that I ovulated, and that normally makes me a bit stir crazy, and you get this scenario...
After work, Friday afternoon. Its hot. We've done most of our work, and are doing catch ups and paperwork. We're relaxed and in a good mood. I grab my clothes to head into the facility. Feeling silly, I drop my shirt on the top of my head and drape the pants around my neck, so that I have a leg dangling down each side of my chest.
I start dancing around the corridor. Saying 'I'm ready to go in now, I'm wearing my uniform'. I turn around and there is the guy I want to fuck, standing right behind me.
