When I was in my early twenties I worked at a surveyors in an office with five other women.
I foolishly began a relationship with my boss and once or twice a week I would be called top his office on the top floor for work related matters primarily, but also for him 'to have his wicked way with me!'
This particular day was his birthday so I thought I'd treat him to something special, so I laid him on his back and...well, you can imagine the rest!
Usually it was all a bit rushed with me bent over the leather sofa which was on one side of the room. He didn't like to wear condoms and I wasn't on the pill so ordinarily he would pull out at the critical moment.
However today he was underneath me so he had less room and came a lot sooner than usual and as a result a sticky mess was left on me and the sofa.
I wiped it up and went down stairs flustered where a couple of the women gave me and each other strange looks. Ignoring them I went to the kitchen to make a drink (after all I had quite a work-out).
When I returned to my desk I found I had an e-mail from one of the other women it simply read

'I think the boss left his birthday present on your skirt, dear.'

I looked down and saw a huge globule of spunk I'd obviously missed stuck to the side of my skirt.

I was so embarrassed I almost passed out. As you can imagine I didn't stay at that job very much longer.
