Then it's agreed:

One more major screwup,
- and I take a cane to your ass.

Late again?

You know the deal we worked out last time.

Am I really to get 12 strokes of the cane?

Yes my dear, you've earned them.
Now remove your skirt and take your comeuppance.

I'm going to sit back and just watch you strip.

Over the desk with you,
- and I want your backside sticking well out

Right in front of her, I whistled the cane through the air a few times to get a feel for its springiness as she watched.

While I did not lay first stoke on too hard, it still brought a pleasant bounce and quiver.

Around the forth stroke her ass really started warming up to the task, squirming this way and that to ward off the sting.

No, that's only been four strokes.

Get back over the desk. You have eight more coming.

That's a nicely stripped bottom. I'm sure you'll think twice before being late.

Now put on your clothes and get back to work.
