My mother used to spank me with a wooden spoon. "Get over here you little shit!" she screamed after I had done something abominable. And each time she spanked me on my bum, through laughing tears I would cry "it doesn't hurt!" when really it did and I was just playing tough. To rehash my precocious youth, I thought I might attempt to upset people (call them names, bump into them on purpose, insult their general appearance, etc.) then ask them to spank me for punishment's sake.
Who knows, perhaps I'll discover a new fetish for myself.
