This is a story of one of the few occasions when I was spanked OTK at school. It happened while I was on schol camp at age 13.
We were playing around on the beach. A few of us were horsing around - disturbing others. The teacher supervising warned us a couple of times, and finally ran out of patience.
He called the two of us over. He told us we were naughty little boys, and he's have to whack us with his gym show. So, in front of the rest of the group on the beach. He tookoff a shoe, and pulled my mate Stu' over his knee. I watched fascinated as Stu's wet Speedoes stretched over his bum. I knew it would be me next.
We had all wondered what 'the shoe' would be like. Both Stu' and I had been whacked by this teacher before, but that was with rulers and canes. Anyway, he drew back his hand, and whached the heel of the shoe into Stu's backside, which quivered from the impact. He yelped in surprise and protesed 'Sir ... !'. The teacher just smiled and told him that this is what came from being a naughtly boy. I was getting worried - this obviously hurt, and I couldn't afford to lose my tough-guy image in front of everyone.
Anyway ,he whacked Stu' 10 times. My mate didn't yelp again, but obviously was in pain by the end. He stood rubbing his bum, and smied sheepishly.
Next I felt the Master's hand pull me over his knee. I was very aware of my bum, vulnerable in damp Speedo swimmers. The first WHACK was a surprise .... a sharp stinging, followed by a warming pain. I was prepared though and didn't cry out. I did squirm a little.
The 10 strokes followed rapidly. And, even with my experience with the cane, I was feeling it by the end, but I managed to keep my composure. Like Stu' when I was allowed up, I couldn't rubbing my bum. Rather embarraingly, my excitement was showing through the front of my Speedos.
After we were dismissed, and allowed to go back to the beach, some other guys came over and asked all about the punishment. They were rivals, and I was suspicious - rightly because they ambushed Stu' and me later that day, and gave us quite a follow-up spanking . But that's the next part of this story.
