The Hour game is indeed excellent fun, I’d highly recommend it to couples, especially those with a bit of extra free time during the coming holidays.
As for a treat if she wins, why don’t you give her a thorough inspection, and examine her thoroughly until she’s soaking wet?
And then read her a bedtime story, a spanking story, of course. Let her play with herself as she looses herself in your words. You might want to put her over your knee though, when the story requires some sound effects.
And then, when you’ve finished, I’m sure she’ll be craving a happy ending of your own invention…
