I set up my Zoom call and make sure you can see me clearly before I launch into my tirade. You're staying with your auntie, and she's informed me of your trouble at school TERRIBLE GRADES! I know I'm only your stepmother but I care about the reputation of this family just as much as people who were born into it, and I'm determined that you won't be allowed to let the side down. I'm delighted to hear that the headmistress dealt with you appropriately with a spanking, and that your auntie did the same when you got back to her house. But I can assure you, it's nothing to what I'll do with you once you're back home in a few days. You'll be the recipient of a long, hard, thorough bare-bottom spanking followed by bare-bottom cornertime. But that's just for the D grades. The E grade will have earned you a severe hairbrushing after your cornertime, which will be followed by more cornertime. And finally, your F grade will learn you a bottom-blistering slippering, after which you'll be a very, very sore and sorry young man indeed!
