Hermione was furious with Malfoy. He was always being a little brat, but he had gone too far this time. Slapping Malfoy after he was being mean about Buckbeak had made her feel better. However, Hermione thought that he needed a more lasting lesson, and she had the perfect idea that would put him in his place.
The teen witch hid behind a suit of armor in the dungeons, waiting for a Malfoy to come. After checking the Marauder's Map, she knew he was coming from detention with McGonagall. Hermione only had to wait a minute or so before footsteps echoed down the corridor. Just as Malfoy appeared, she pointed her wand and uttered the spell Reducio.
Malfoy did not know what hit him as he was blinded by light. The teen suddenly felt like he was falling down a hole. A moment later, the sensation passed, though he was still disoriented. Nothing looked right anymore. It took Malfoy a second to realize that everything around him was now huge. A booming noise like a cannon startled him. In the distance, Malfoy could see the giant figure of Hermione Granger coming toward him. Each of her footfalls was loud to the tiny boy. Huge, house-sized sneakers stopped just short of him.
Hermione looked down at the shrunken Malfoy. He was still too shocked to do anything. It was tempting just to squash him like a bug. However, there would be no fun in it, so she bent down and scooped him up. "Hello, Malfoy," she said with a smug smile, examining him in the palm of her hand. She poked him with her finger, enjoying it when he lost his balance.
It took him a second to get his voice. "What the hell did you do to me, you filthy mudblood." Malfoy tried to sound intimidating, but he was still pretty shaken. Plus, his voice was tiny compared to Hermione's.
She laughed. "Well, I would have thought it was obvious, but you can be a little dense, so I will fill you in. I shrunk you down to size. It is time someone taught you that you can't always act like a spoiled brat."
"You...you can't do this," retorted Malfoy. He reached into his pocket and pulled out his shrunken wand. Before he could do anything, Hermione flicked it to the ground and crushed it beneath her shoe. "Wait until my fa..."
"Your father hears about this," interrupted Hermione. "You are so predictable. The moment things get tough, you go crying to daddy. Well, not this time." She closed her fist around the tiny boy to show her dominance over him. Malfoy tried to squirm free, but it was to no avail. His giantess captor made her way out of the dungeons.
At that exact moment, Snape appeared. Hermione quickly put her hand behind her back. The last thing she wanted was to get caught for what she had done, especially by Snape. "What are you doing down here?" he asked suspiciously. The teen knew she needed to better hid the shrunken Malfoy to avoid getting caught. Unfortunately for him, there was only one option. Hermione discreetly pulled the back of her skirt forward and dropped the tiny boy in her underwear.
"Well...I...I.. misplaced my notes and thought I might have left them in the potions classroom," she lied. Meanwhile, Malfoy was in disbelief that the which had trapped him against her squishy butt. Her skin smelled like roses and was warm.
Snape's eyes narrowed, "What do you have in your hands?"
"Nothing," she replied, showing the hooked-nosed teacher. "May I please leave now? I have homework." In response, Snape just turned and walked away. Hermione let out a sigh of relief before climbing the stairs. Each step she took jostled the tiny boy around. Hermione could feel him sliding further into her underwear and was worried he might fall out. There were too many people around to risk exposing what she had done to Malfoy.
Getting an idea, Hermione sat down on a bench. Malfoy could feel the entire weight of the giant girl but miraculously was not crushed. She wiggled around until he was more firmly secured between her butt cheeks. As she stood up, Hermione smiled to herself. It seemed like a fitting first punishment for the school bully. Admittedly, it also felt good having him trapped up her butt. She decided…
