Sounds like a great idea, as I often have new ideas on things that could work, but don't necessarily want to try them on my slave if there are some unseen pitfalls.

One thing I can think of off the top of my head is Vicks vaborub, some people have never heard of it, but it's this menthol oil you rub on your chest when you're congested/ have a flu. But I never hear about it as a dare or punishment, to put vaborub on or in the anus. I'm assuming it would give quite a sting, but more hygienic then toothpaste. Any volunteers for testing this out? I would also want to know how long the effect lasts and how it is compared to other substances in the ass. Thanks in advance!
