A Part of the Family

 It's been a few months since Sugar Belle married Big Mac, and one side of that was gaining a little sister. So she decided to treat Apple Bloom like a little sister. Today "little sis" learns that means when Bloom is naughty and disrespectful, she goes over Sugar Belle's lap.

 

Apple Bloom has never been spanked with a hairbrush before, and is horrified to learn that despite its common and even prissy appearance it's nearly as painful as Applejack's paddle.

And today she's at a double disadvantage. Those cutoff shorts mean her sit-spots get targeted, and she's determined not to get a three-peat wardrobe malfunction. Will she ever switch to a more conservative style of dress/stop getting into situations that result in her getting spanked?

...Not bloody likely.
