My first serious spanking occurred on my first day in Junior High School. Our Physical Education coach gave us 2 rules. We were to be in full dress (T-shirt, shorts, and jock strap) and were to shower after class. Well, I was a modest 12 year old and didn't want to expose my chubby pre-puberty body to the others. Well I got caught! While the other boys were showering, our coach came out in the locker room and told me to stip. I reluctantly did this, and I expected to merely have to shower, but to my horror, he told me to get in his office. Without saying a word, he pulled out a hard plastic paddle and instructed me to brace my hands at his desk. He then walked behind me and gave me 10 hard whacks with the paddle. The door was open, and all the other boys knew what was happening. Now with a red face and bottom, he brought me to the showers and made me shower while he watched. By now, the other boys were done, so they got to watch all of this also. Needless to say, I never skipped a shower again. After a couple weeks of school, one day he asked all of us to line up in the locker room, before we went upstairs to the gym. This was our first jock strap check. We all had to purchase a jock strap from him, and he wrote our last name across the back of the waistband. Well, we were all told to pull down our shorts and anyone without his supporter on was told to go to the other side of the room. Thankfully, I was wearing mine! About 5 boys were found wearing their briefs, and 2 of them had their jocks in their lockers. These 2 tried to beg their way out of their unavoidable fate. He went to his office and emerged with his plastic paddle, and had the 5 boys bare their bottoms and bend over, bracing themselves at the bench. They all got 10 good whacks, in front of the rest of us.
