Desires—A Harry Potter Fanfiction
A/N: Happens after book 7, not all of Deathly Hallows is relevant (i.e. some people didn’t die in the final battle that did in the book/movie). EWE. Harry/Hermione. AB/DL
Harry and Hermione were in Number 12 Grimmauld Place getting ready to return to Hogwarts for their delayed final year. Ron and Ginny were at the Burrow with the other Weasleys. The final battle had been won the previous May, but with heavy losses, including Lupin, Tonks, and both of the Creevey Brothers.
Hermione and Harry had gone to Australia to find her parents, and had brought them back to England with restored memories. The majority of the rest of the holiday, Hermione had spent with her parents, only coming to Grimmauld Place on nights and weekends to be with her boyfriend, Harry Potter.
“Harry, what's that in your bag?” asked Hermione, as she spotted a white plastic object in his bag. “Harry, why do you have nappies?”
“Um...” said Harry.
“Honestly, Harry, I don't care,” she said. “I just want to be your friend.”
“I'm a freak, all right?” said Harry. “While you've been gone, I've wanted to let go of my life, forget what it is to be me. I like wearing nappies. Sometimes Dobby takes care of me.”
“You are not a freak, Harry” responded the witch. “It’s only natural to want to regress when someone has lived your life. Tell me more. What type of nappies do you wear? What other baby things do you use?”
“It really depends on my mood,” said Harry. “Sometimes, I want to go all the way, and wear actual nappies. Other times, I want to pretend that I am a potty-training toddler, and I wear Pull-Ups. I don’t really have any other items.”
“So, you want someone to take care of you?” she asked.
“Yes,” said Harry. “Dobby is really good at it.”
“I could take care of you,” suggested Hermione. “After all, we share a bedroom this year.”
“Hermione, you don’t have to,” whined Harry.
“Harry, you listen to me,” said Hermione. “I’ve wanted to be a mummy and have children ever since I was a child. I wouldn’t have offered if I didn’t want to do it. Now, you be a good boy, and finish packing your things, and mummy will be right back, okay?”
I’m getting into the caretaker role quicker than I would’ve thought , thought Hermione as she exited the room, heading to the front door. She got her Muggle money, and headed towards the closest Tescos.
When she got there, she headed towards the baby aisle, where she got a couple cases of nappies, training pants, and Drynites (pyjama pants for bedwetters), along with nappy rash cream, talcum powder, dummies, baby wipes and bottles. She knew that there was a spell that could resize the nappies so that they would fit Harry—the spell was even good enough that the enlarged item would have an enlarged capacity—in this case, a proportionate capacity scaled to Harry’s output.
After spending well over £100 on the items, she walked back to Grimmauld Place.
“What did you buy?” asked Harry.
“You don’t need to know,” said Hermione. “Now did you finish packing like a good boy?”
“Yes, Hermione,” he replied.
“Do you have to go potty?” asked Hermione.
“No, mummy,” responded Harry, getting into his role.
“Let me know if you do,” she said sternly. “Mummy will be very cross if you have an accident.”
I should test Hermione to see how far she’ll go, thought Harry.
Not a half-hour later, when Hermione and Harry were at the kitchen table, she noticed him squirming.
“Harry, do you have to go potty?” she asked again.
“No, mummy,” replied Harry with a straight face, as he released his bladder into his trousers.
“Harry, you just had an accident! Why didn’t you tell me you needed to go?” asked Hermione. “Go to your room. Mummy is very cross with you.”
After he left the room, Hermione got the box of nappies out of her bigger-on-the-inside bag, and enlarged one of them. She took one of the dummies and cast a spell on it to sanitise it. She then took the nappy, the wipes, and the dummy up to his room, hidden in a bag.
“Get on the bed,” she said sternly. “And take off those wet clothes.”
He started to take off his clothes, but was too slow, as Hermione decided to take the rest off him. She pulled him over her knee, and gave a couple quick swats to his wet behind.
“I guess that you aren’t ready for big-boy pants just yet, Harry,” she said. “Lie down on the bed.”
He did as she asked. He was unprepared when he found himself sucking an oversized dummy.
“Maybe I’ll start potty-training you again tomorrow,” she said. “But today, you are wearing nappies.”
She pulled his legs up, and put the nappy under his behind. She pulled it up in the front, and fastened the tapes. It was a perfect fit. Harry looked so cute with his nappy on.
“I just realised that you have no toys to play with when you’re little like this,” said Hermione. “I have to get you some trousers, and then we can go to the toy store. In the unlikely case that we meet someone we know, then we are shopping for Teddy.”
She noted the look on his face. “I’m not ashamed of you and your desires, Harry,” she said in response. “No, I just don’t want you to be embarrassed. We can also pick up some clothes for you and Teddy as well.”
“What about my nappy?” asked Harry.
“You’ve proven that you can’t go to the potty like a big boy, so you have to wear it,” she said, as she found a pair of jeans, and pulled them on over Harry’s nappy. She got Harry’s credit card, and they left for the local toy store, where they literally bought thousands of pounds worth of toys. They then headed to the clothing store down the street, where they bought another thousand pounds worth of baby clothes and accessories. As soon as they left a store, Hermione would put the shopping into her handbag (which, in addition to being Bigger-On-The-Inside, also had a mild Notice-Me-Not charm on it so that the Muggles wouldn’t see it).
After they were finished with their shopping, they stopped at a hamburger restaurant to have a bite to eat. Whilst they were there, Harry had quite a number of beverages, as he was hoping that the game would continue. When they got home, Harry had an announcement.
“Mummy,” he said as Hermione was trying to put the shopping away. “I had an accident.”
“Harry, that’s what your nappy is for,” said Hermione. “I’ll change your nappy in a little while.”
Meanwhile, Harry was experiencing a new sensation, one that he hadn’t felt during playtime before. He had to poo. When he was with Dobby, he would always go to the actual bathroom to do that. Since Hermione-Mummy bought all that stuff for us, I’ll try it, he thought. Mummy will hate it!
Not five minutes later, Hermione came into the room, and immediately noticed a certain stench coming from Harry.
“Did you go poopy in your nappy?” she asked him. “Lie down on the bed.”
She cleaned him up, and was about to put a new nappy on him, when she noticed the time. “Actually, I think that it’s time for little Harrykins to have a bath,” she said grinning, almost willing him to stay in character.
“No bath! No bath!” Harry shouted as Hermione dragged him to the bathroom, and shut the door.
After a quick bath, they went to bed until the next morning, 1 September.

“Harry, you have to wake up!” said Hermione.
“Mummy, I’m tired,” said Harry.
Hermione noticed Harry’s wet nappy, and got the supplies.
“Harry, you’ve got to wake up, and we’ve got to stop playing for now,” she said. “We can play nights after our homework is done.”
Harry woke up, and noticed what Hermione was holding. “Hermione!” he said. “It’s time to get up already?”
“Yes, Harry,” said Hermione. “We have to be on the train by 11. Now, I’m giving you a choice. Do you want to be full adult, and wear underpants, or mostly adult, wearing Pull-Ups?”
“I’ll wear the Pull-Ups, as long as you can charm them so nobody notices the difference,” he said.
“Of course,” said Hermione.
The game ended, and they started to get ready for their final year at Hogwarts as students.
