I am a man in my 60’s who as a child was spanked regularly by my teachers, my aunt and my grandmother. My Mother didn’t spank me but my father caned me.
All my punishments except at school were always on the bare bottom. At school this was occasionally the case but mostly over my clothes bottom.
If this was done by female teachers and my aunt ( who was only 8 years older than me) I would experience an erection.
Once when I was staying with her I came back to her flat from the shops but had forgotten 2 items she wanted. She was having a coffee with three of her friends, all a similar age. I was 13 so they were all about 21 or so.
She quizzes me about the shopping and because I had forgotten the two items she told me I was going to be spanked in front of her friends. It was a hot summers day, all I had on was shorts , pants a t shirt and sandals. She made me take off my shorts and pants and put me across her knees. She pulled up my t shirt to my shoulders and spanked my bottom for what seemed like 10 minutes whilst chatting to her friends. I was then fold to remove my t shirt and sandals and stand in the corner with my hands on my head until her friends had left. I was then given a slippering whilst touching my toes.
