It hurt quite a bit, but I was sure that it must hurt much more if administered by someone else. To compensate, I decided to steel myself and administer many whacks in quick succession – with my trousers down.
I would decide on a number and be determined that they must all be delivered no matter how much it hurt. More often than not I bottled out before receiving the full complement. I got really cross with myself as I knew that if it was for real, the teacher wouldn’t. I was puzzled that invariably by the end of the session, my willie had a bone in it and I had trouble pulling up my pants and trousers. I had no idea why this happened and I remember being a bit worried about it. It always went floppy again soon afterwards so all was well.
