Ich masturbiere im büro, während kollegen nicht bei der arbeit sind

I often go to the office without panties. This makes me very excited and I wait for my colleagues to go out for lunch for a while. At this time I manage to quickly have an orgasm. I'm not afraid of being caught, since I won't get dirty with sperm, and the lubricant from my fingers is easy to wipe off or even lick off if I am in the mood
