There is an extraordinary mythology about the Victorian--and in this book, contemporary--disciplining of young English women. The author, who was an English school mistress herself, celebrates it in an erotically charged novel of sensual delight.
I have actually owned this one since it was originally published so I went and found my own copy. I also scanned in the cover you now see displayed.
Essentially it is a series of short stories about various school girls in various situations. Although there are a couple of exceptions like the story of the young woman who sneaks into her cousin's class room and is caught by the Headmistress who demands that he punishes her. Or Lucy, who has an interesting time as the new biology teacher at an all-boys Boarding School. Or Jill, who has an interesting time with her boyfriend after she dresses up in her old school uniform.
But I have to admit that my favorite has always been "Awaiting Execution" where Lynne is forced to wait for her turn with the Headmaster - who seems to be getting more out of sorts with each of his victims.
