Last night I stayed with a friend, and we watched an old spanking film. The girl in it was spanked over her knickers: white cotton, high-leg, snug but not too tight.

“That’s pretty much my perfect kind of knickers,” said my friend, sounding awfully content.

I saw what he meant, but I wasn’t sure I had the same love of a particular kind of knickers. White cotton is nice, but, say, polka-dot is also cute. Then there’s silk. Or lace. They’re all very spankable kinds of underwear.

Do you think a specific kind of knickers is particularly suitable for a spanking, or is the choice dictated by the occasion?
