Before and After but surely not During.

It's always been "before." The immediate anticipation ( if not known in advance of the spanking) as well as the humiliation immediately before placing oneself across her thighs, which was always bare. The feeling of your skin, ( if being spanked in the nude) on her bare thighs. The actual pain is forgotten except that you tend to want the actual spanking to end since the actual pain was terrible. You hope that the spanking will end shortly but the spanking continues. To remember that time when total resistance is lost and the continuation of the spanking, at that point. For me, the "after" did not exist.
