“You were late returning this book, weren't you, you naughty pony?” Twilight said, scolding the shy yellow pegasus cowering before her.

“I'm sorry,” she said, stammering the words out. “Are you going to punish me?”

“I'm afraid I'm going to have to,” replied Twilight, putting a note of false sadness into her voice while levitating the book in her magical grasp and using it to swat the pegasus' flank several times until it was red. She didn't want to do this, but standards had to be maintained. “Have you learned your lesson now?”

“Yes, Twilight, I have,” said the pegasus, whimpering slightly.

“Good.”

“One of these days, we're going to have to have a talk about your weird sexual fantasies, dear,” said Princess Celestia, removing her Fluttershy costume.

“Like you're one to talk,” Vinyl Scratch said, removing her Twilight Sparkle costume.
