In the early 70s, bare bottom or even naked spanking was very common in our village. My last punishment took place when I was 14 (and in a few days would be 15).
During the hot summer, I planned to take a shower and I thought that there was nobody home. I stripped off all my clothes and went to the bathroom. I forgot that my cousin was staying in our home – she was 2 years older than me. Her parents were out of town.
