Interstellar spanking: What Emily is up to

I'm having a really fun time with this one. The set-up is so cool (if I do say so myself) that I don't want to spoil it, so you'll just have to figure out what you can from the tease…

Kayla screamed and screamed, and Joe just kept whipping her with the strap: in the middle, on each cheek, on her thighs, methodically and quickly, up and down. 

"All I wish you to remember, girls, is that this is what happens when young women decide they want to try to bring change too quickly. Conduct unbecoming a young woman is what we call it. It's not a crime, but, as you can see, your guardians, who are responsible for you, will not take kindly to it." Marjorie's voice was hardly audible now, to Kayla, over Melanie's cries of agony, and her own. 

All Kayla could see was the door, and Fergus standing next to it, his back against the wall, not taking his eyes from the spectacle, but clearly not enjoying it. Kayla wanted to cry, "Help me, Fergus!" but she knew it would only do harm. 

"I'm done," Joe said. 

"Me, too," said Bill. 

It was over. Or that part was, at least. Kayla had never imagined anything could feel this bad, that was supposed to be for her own good.
