Looking for Janus story.

Hi, can any one help me? I'm looking for a story which appeared in Janus many years ago, late70s/early80s. It was about a new headmistress at a private girls school. C.P. had officially been banned but she found out that the gym mistress could punish the girls if they didn't want to do detention. Long story short the gym mistress ended up whacking her and one thing led to another.
Does any one know if this story is in the library? Any help gratefully received, Fram.

Your description stirs a vague memory... If you can't find it here on LSF, try Dimitry's blog ( britishspankingmagazines.blogspot.com ). He scanned for years a lot of Janus and other old British magazines. Who knows...
