Had gone out drinking and woke up late. Put on headphones and cranke a little music and started reading stories from this site mixed in with a little you porn. Completely forgot it was the day for the cleaning girl to come.
I don't know if she forgot to ring like she normally does or if I just didn't hear bell over music. First I saw was a little motion out of corner of eye. Was right at point of climax and turned toward movement just a bit. She had headphones on too and must not have realized I was home. So there I was stroking like a mad man turning toward her to see her covering her mouth in shock. Was too late for me. I had passed point of no return. I'm sure I had fucked up expression on my face as I tried not to cum. Cock was pulsing and I clamped down. But had to release cause it hurt so bad. So there I was cumming all over my stomach and hand as she watched saying "oh my god!" Then giggling in nervous amusement. She then was saying "I sorry" in broken English.

I cleaned up with the tissue I had on the desk I'm sure blushing in total embarrassment.
