I had a very…elaborate dream some nights ago and I decided to draw it out. From what I can stitch together:
Pinkie Pie is the Spank-Master General of Equestria. When the sun goes down, she suits up, quite literally, and dishes out discipline. And her latest victim tonight is Princess Celestia, who was patiently waiting for Pinkie to come. Waiting around in a pair of silk bloomers and frilly top; old fashioned but comfortable.
Because comfortable was the last thing she was going to be when Pinkie dragged her across her lap, roasting her rump good and proper. It was 'overdue' Celestia claimed. After all, her last spanking was so long ago she couldn't remember how it felt.
When it was finally over, Celestia would be sleeping soundly that night. Sore and on her belly, but soundly.
But for Pinkie Pie, it was going to be a very long night…
At least, that's the abridged version of my dream, lol.
