Headmistress Wood is showing a new foreign exchange teacher around the school and eventually she gets to the detention and punishment room. She makes him aware if pupils are naughty they get punished. Then she informs him he's to have an induction spanking to make sure he'll know what to do and also in case he does anything wrong, he'll get punishments too! So he goes over her knee and she starts spanking his bottom with her hand. After a little while she also uses the plimsoll on his bottom. He is now very clear how things work at this school.
