One advantage back in the day of wearing our girdles at school was that we didn't feel it at all that much - you don't really feel anything when in a girdle!
I believe so, yes - but I can't speak from experience because I've never *yet* been spanked in mine. I'd certainly be game to find out: the tight material is said to intensify the spanking when you're girdled, holding in the heat more. It makes the experience quite erotic, apparently, though it also depends on what you're spanked with.
There's an APP for that
Ha! Imagine the reverberation. The spanker better wear a catchers mitt
