I know, this is an old entry, but i think, it is still of interest.
'Keep it simple' is my guideline.
You want supervision for corner time?
- Balance a book on your head and confess if you couldn't keep it there.
- Hold a coin with your nose!
- Hold a book between your open hands behind you.
- Keep a pencil upright between your feet.
- Hold a book between your knees.
- ...
With a bit scripting, you can even add an apropriaaaate control question to the code; if you fail, it's another corner time!
But if you do, keep in mind that thes corner times will be REAL corner times, hard to perform and demanding.
Also, a spanking isn't really controllable by a microphone or other electronic means.
What does it to you?
1. It inflicts pain
2. It will redden your skin (or even give bluish marks)
How can pain be gauged?
Maybe if it's so severe, that it will force you to suffer anoter pain just to stop it?
How can a red skin be gauged?
Maybe by taking a picture together with a color card?
You could use a color picker (Like in Gimp or paint) to see if the marks are sufficiently red or blue. Maybe you even get a bonis if you didmore then necessary?
But maybe a simple way will do: Cover your butt with a newspaper and hit it until the paper is torn? That should make sure that you put enough effort in it.
