office sex!

So a coworker and I were studying for an exam that's next week and it was late in the evening and a trainer had locked the door and told us to just shut the door when we leave and well we had sex on the desk. It was exhilarating and nerve racking at the same time. And it was also just a one time thing. I can check that off my bucket list. 
Has anyone else ever had office sex?
