Early Bare Bottom Spanking
When young I went to school we had nuns. They would spank you themselves. Older nuns who still taught, or tutors would be assisted in this duty by younger nuns who volunteered for the extra duty and if you did something to upset the old nuns you would really get it.
Normally you would be brought into the cloak room. The nun would sit down and you would stand in front of her. She would pull your pants down. You would lift your shirt and undershirt " over your belly button" and then they would pull your underpants down.
Then she would put you over her lap and spank you. Some would talk to you before, during, or afterward.
Very rare was the spanking done in front of the class. Maybe once a year and only happened to me once.
