I found Akane's spanking in Dr.slump.
In this clip,Akane is spanked by her classroom teacher Midori with a roll book.
Because she had a whisky secretly in classroom (to drink with school meals?) and thanks to Arare her friend and Heroine in this story that came to light.
We can watch/see her spanking in new(second) version anime and in original Manga.
cf. In first anime,we can watch Arare's punishment only...
