I have quite a collection of slippers. Synthetic soles and rubber ones. My rubber soled slippers are my favourites for a nasty sting. What a lovely noise they make when they land on a naughty bottom too! I love the fact they're such good implements that I can be wearing all the time inside the house for a spanking at any time.
Being a school Headmistress and having to punish naughty teachers and schoolboys with a good slipper spanking is something I highly enjoy, I especially like getting reprobates over my knee, with their trousers down and spanking them with my slipper for a lesson they won't forget.
Apart from slippers, I have school gym plimsolls, flip-flops and sandals to spank bottom with. Something for every naughty bottom!
