I found this picture on Panty744:
After judicious consideration, I think a martinet would be just about the perfect toy for this situation. Or some sort of multi-tailed whip, anyway, something with a lot of tails and some bite. This would do nicely.
I concur, SpankBoss. I also think a pair of safety shears to snip the crotches of those panties would come in handy as well.
