When I was in 3rd grade, a nun made me put my hands, palm up on the desk. Then she smacked each one of them with a ruler. Although I was too young to equate it to kink, the feeling was powerful. I sat there looking back and forth between the red marks on my hands and her face. She was very pretty or it may not have had such a euphoric impact. On recess my classmates comforted me. It was my first lesson in aftercare. LOL.
