Occasionally I get angry and not in any mood to be told what to do. this happened the other day with my mentor, He told me I was going to get a spanking for something that I felt did not deserve one. It was silly and I felt he was just being mean. so instead of preparing myself to be spanked, I decided to argue and fight him over it. I became so defiant in the last thing I wanted to do was submit for a spanking. It escalated to the point where he forced me over the back of the sofa and whipped me so hard with a belt it ended up cutting in some places, and he ended up leaving me alone for the rest of the night.
It was not for some hours later that I started to realize why it got out of hand. it was through my actions and willful behavior that I defied him. I may not have felt that I deserved to be spanked and certainly not as severely as I was, but through my actions I turned a somewhat hard hand spanking into a beating. I brought it on myself by allowing my emotions to override my duty. In the end I received the spanking that I deserved.
