A useless employee like me who gawks at a beautiful office worker's buttocks in the office

I am a useless employee who has been making mistake after mistake at work since this morning! I'm so bad that I could be fired at any time. While I was picking up the papers I dropped, my beautiful boss was giving me a lecture, but I could see her underpants! I get carried away and get a closer peek at her pants later, but I'm easily caught and get a big eyeful...but then she starts having a fit and we have sex in the office! I've decided, I'm not going to quit my job until I've cum inside her pussy.
