They say confession is good for the soul so cleanse yourself of past indiscretions and share your nasty histories with the rest of us non-judgemental souls.
I was at work once in an office and had some particularly good sex the night before involving some rather hot role playing. I found I couldn't hep thinking about it and that lead to an erection which just wouldnt go away. So I took myself off to the toilet and slid my pants down to free it up. It felt kinda strange but I was so horny that I was beyond caring about the niceties. I grabbed my hard on and closed my eyes reliving the sex from the previous night as I stroked myself to orgasm. It wasn't easy because I was half listening for anyne else who might come in but it was kinda hot too. In the end I returned to my desk and my work with the knowledge of what I had just gone and done but no-one else would have suspected. It made me smile....
