Caught naked at work

I decided to do another risky jerk off video at work.

I found a spot where the cctv couldn't see me then set up my phone to record.

Starting to rub my cock through my trousers taking off my shoes. I undid my shirt, then trousers, taking them both off followed by my socks and finally my underpants.

Just as I was getting into it an off duty work colleague came in! I tried to hide behind a door but she must have guessed something was going on... I hid behind a door and quickly said I ripped my trousers and was just checking them.....
