Harry heads to the Great Hall

With a start, Harry felt his stomach rumbling. His recent... workout had left him hungry, and a quick glance at his watch revealed that it was still early enough for him to grab breakfast.

"Come on Hermione," he said, "We're going to the Great Hall."

"Okay," she replied, "I just need to get dressed." Harry watched with a smirk as she strapped on her bra, pulled her panties on, brushed down her strawberry blonde hair, and checked her make-up in the mirror. She was a completely different person now than she had been only about an hour ago.

Harry took her hand, and they walked out of the Room of Requirement, into the corridor, Harry still naked.

As they made their way down to the Great Hall, they passed several people, none of whom even glanced at his dick or Hermione's tits. They seemed to think it was fine for him to be naked and for her to be in lingerie.

When they entered the Great Hall they got more of the same. Disinterested looks all around.

The professors were all there, sitting at the head table, but there were only a smattering of students sitting at each of the house tables. Harry headed straight for the Gryffindor table, sitting between Neville and Ginny. Hermione made to sit opposite him, but he kept his grip on her hand and pulled her onto his lap. Ginny and Neville looked startled at this. Harry frowned at that, before he remembered. While his and Hermione's state of undress was normal, their relationship wasn't. Well, he could soon fix that.

"Everyone knows that Hermione is my girlfriend." He said, and Ginny and Neville's startled looks quickly turned into ones of mild amusement, as if it was an everyday occurrence that Hermione sat in his lap while he was naked.

That fact, and Hermione very intentionally grinding slightly in his lap, made Harry realise something that hadn't quite settled in yet. He could do anything. Absolutely anything. Everyone and everything was his to do with what he pleased. He deserved a bit of happiness in his life, and now, he could take it. The world was his oyster.

With that realisation, Harry turned to Ginny. Why settle for one woman, when he could have two?

"Ginny?" Ginny turned to look at him.

"Yeah Harry?" she asked.

"You're my girlfriend as well, and both you and Hermione are completely okay with sharing, right?"

"Of course I am, Harry," Ginny said, while Harry pulled her closer towards him. She snuggled into him, resting her head on his shoulder. "And what sort of woman would I be if I wasn't okay with sharing you?"

Harry grinned. He reached his arm around Ginny, grabbing one of her tits. She tried to pull away, confused.

"You love it when I do this." Harry quickly said, and Ginny stopped pulling away, instead turning to give Harry better access. "Oh, and you have the same uniform as Hermione," Ginny's uniform fell away, leaving only black lace lingerie in it's place. Harry nudged Hermione off of his lap, and stood up, gesturing for Hermione and Ginny to do the same. They did, both of them smiling at their boyfriend.

Harry couldn't help but laugh. Professor Dumbledore was sitting at the head table, laughing at his own joke, not even caring that a dozen metres away one of his students stood naked, staring at two others wearing nothing but lingerie.

He looked at his girlfriends. Ginny was beautiful, no doubt, but Hermione was perfect. Of course, Ginny would be perfect soon too, exactly like Hermione. Staring at her, he pondered what changes to make, when an idea came to him. Why not try something a little bigger with Ginny? With Hermione, he had made her love him, made her fuck him, and then changed her appearance. What if he changed Ginny's entire life? Made her completely different, in almost every way? Could he do that?

There was only one way to find out. All he had to decide was how he was going to change Ginny's entire life.

It didn't take him long to decide. He was going to change everything about Ginny, make her perfect, exactly like Hermione was now.

"Ginny, you are Hermione's identical twin, in every way. You look like her, talk like her, think like her. You have never been a Weasley, you have always been Emilia Granger." As the words came out of Harry's mouth, he could hardly believe what he was saying. He was taking Ginny's entire life, and completely transforming it into something else. Everything about her was going to become identical to Hermione. It had already started.

Ginny, completely unaware of the changes, had just grown about three inches, as tall as Hermione was. Her body was shifting and shaping, slowly changing bit by bit. Her breasts grew considerably, and her ass did the same. Her hips got wider while her waist got thinner, adopting Hermione's more hourglass shape.

Harry couldn't help but get aroused as the changes played out in front of him. He watched as Ginny's hair grew longer and longer, until it reached down to her collarbone. Its colour shimmered, changing to the exact same shade of strawberry blonde as Hermione's. Finally, all that remained of Ginny was her face, which had already started to change. Her nose shrunk slightly, while her cheekbones became more prominent. Her eyes changed colour, shifting from blue to Hermione's beautiful brown. Finally, Ginny coughed slightly as her voice altered itself from her slightly deeper tones to Hermione's higher ones.

While all this was going on, inside Ginny's head a whole different set of changes were happening. Her memories of growing up in the Burrow with her brothers were fading, changing to ones of growing up just outside of London with her sister, Hermione. She forgot about her love of Quidditch, replaced with a love of books. She didn't remember meeting Harry for the first time just outside of Platform 9 3/4, instead she met him on the train, with her sister, while they were helping Neville look for his toad. She remembered falling head over heels for Harry after he had saved her and her sister from the troll. She remembered when she found out that Hermione loved Harry too, how conflicted she had been. She remembered resolving with her sister, that if they ever told Harry about their feelings, they would share him. She remembered only half an hour ago, both of them telling Harry how they felt, and the joy when he had returned their feelings. She remembered the glorious sex they had shared.

Finally, she shook her head, feeling a little dizzy. She looked to her left, and saw her sister looking at her.

"Are you okay Emilia?" she asked, concern for her twin evident in her voice.

"Of course I am," Emilia Granger replied. "Why wouldn't I be?"

Harry had the biggest smile on his face. He had just erased someone from existence. He had completely destroyed Ginny Weasley, and created Emilia Granger in her place. Lives, history, time itself had been altered with a few words from him. Now, two twin sisters looked at him lovingly, identical in every way. In thought, in feeling, in body, they were the same. They were his.

"What are you thinking about?" They both said, in unison.

"I was thinking that we are going to have a threesome, right here, and that everyone else will think that is normal."

"A threesome?" Hermione asked. "I mean, we're okay with sharing you, but we don't think of each other in... that way."

"Yes you do." Harry said. Hermione and Emilia blinked, and then looked at each other with a hint of lust in their identical eyes.

"You're right." They said at the same time, moving closer to each other, while Harry conjured a mattress between the Gryffindor and Ravenclaw house tables. The two sisters were inches from each other now, and in less than a second, their lips had met, and their hands were all over each other. Harry grinned, and guided the two to the mattress. He lay down first, and the sisters separated themselves long enough to lie on either side of him. He couldn't tell which was which anymore, which made him harder. The left one went down to his crotch, and started to give him a blowjob, her painted lips circling his dick. The right one began to kiss him, her strawberry blonde hair brushing against his face. Harry just enjoyed himself whilst the two woman attended to him.

After a few minutes of pure bliss, Harry decided to change things up a little. He pulled away from the one who was kissing him, and grabbed the hair of the other one, pulling her off of his dick. Spinning her around, Harry pushed her down on the mattress, and quickly shoved his cock into her pussy. She moaned loudly as he pounded her. The other one grabbed her sister's tits and started to fondle them, switching between that and rubbing her breasts on Harry. Harry felt the pussy twitch and spasm around his cock, whilst the sister is belonged to screamed in pleasure.

All around them, no one cared about the threesome happening metres away from them.

Harry continued this for a while, switching between sisters occasionally. After some time, he felt his cock tense, and he came right into whichever one he was fucking. As soon as he removed his dick, the sister he was fucking got up, letting Harry lie down on the mattress, while the other one started to give him a blowjob. The first sister began to kiss him up and down his body, as though she was worshipping him.

After a while Harry sat up, and the two sisters sat on either side of him, one playing with his cock whilst the other stroked his chest. Looking around, everyone else had left the Great Hall to go to their classes. They were completely alone now.
