Corner time is a good time. For reflection on misdeeds (and schoolwork not done), and consideration of what Master will do about it. There’s a tawse in her near future, and she knows it. But there’s always comforting afterwards, so that’s not so bad.
It’s also not a bad time for Masters. Arethusa looks so sweetly obedient. And a Master can always walk past while she’s waiting, and check out her arse. Are Masters sleazebags? Well, sometimes, when we’re lucky, and we’ve been good, we get to be.
