Humiliation in office [F20]

So I was doing my internship once in a local company in my city. I was not expecting this to happen here. Everything went well but one day I made a mistake that I thought was small ( error in the newsletter that they share with the client). My boss who also happens to be the owner of the company gets furious and calls me in his office where other chairmans ( also his family members including his son) were there and said they would either fire me or i take a punishment which remains inside the room only and everything continues normal. I was scared but did not want to leave the internship too, I was 20 at that time, pretty naive. I decided to go with taking the small punishment. He asked me to face the wall. And then he asked me to pull my jeans and panty down. I was shocked and froze. My mind was not working and I don't know why but I continued to follow his orders. Now my bare ass and pussy is visible to all. His son asks me to bend on the table and give me 20 spanks. I cant forget how fucking humiliating that experience was, in front of all the bosses. But yeah, this led to me being cautious and never committing any mistake ever again, so their purpose might have been fulfilled.
