Harry fixes Hermione, and then 'fixes' her some more

Whatever he did, he had to undo his mistakes first.

"Hermione, you're a brunette, not blonde, and you hate Rita Skeeter." He said. The familiar look spread across Hermione's face, while her hair shifted back to its normal brown.

Harry was about to leave it there, when a thought occurred to him. Sure, he could leave Hermione how she was, but with these powers, he could improve her life in so many ways. Nothing big, just small changes. Besides, he rationalised, it would be a good way to test his powers.

He didn't, however, want to do this in front of other people. While it didn't seem like anyone else noticed the changes he was making, he wasn't sure yet, and he didn't want to get into any trouble, especially when one careless sentence could do any number of things that he might not actually mean.

"Hermione, you'll follow me to the Room of Requirement, and you won't think there's anything strange happening." Hermione nodded.

"Of course Harry, why would there be anything strange happening?" Harry couldn't help but grin at that reply. He had never been someone who enjoyed being in control, but something about this level of control, of power, it did make him a bit giddy.

He and Hermione stood, and made their way out of the Common Room. As they made their way to the seventh floor, he and Hermione made small talk, and she didn't see a single thing odd about what she was doing.

With his knowledge of the castle and all of its shortcuts, it didn't take them long to reach the Room of Requirement. Pacing up and down in the corridor, thinking over and over, 'I need a room to speak with Hermione privately.' After a few seconds, the door seemed to melt onto the wall, the Room revealing itself.

He stepped through, with Hermione following. The door disappeared behind them, vanishing until it was needed again. The room they were in was fairly simple, and looked quite similar to the Gryffindor Common Room. There was a fireplace at the back of the room, surrounded by couches, and tables in the corner, some with books stacked atop them.

"Stand right there Hermione, and don't say anything." Harry said, pointing at the centre of the room. Hermione nodded, and walked over. Now, Harry needed to concentrate. He had to choose his words carefully, he knew that. One wrong word and he could make Hermione a muggle by accident. He could probably fix anything he messed up, but he didn't want to take chances.

Okay, he should start small.

"Hermione, not only are you the smartest witch of your age, but you also always find time to relax so you don't over-stress yourself." There. That was good. Not only had he fixed his friend's stress problem, he may have just given her an intelligence boost. Harry was fairly confident that Hermione already had been the smartest witch of her age, but she certainly was now.

Now, what to change next? He could seemingly do anything with these powers, there were so many options available to him. As he thought, he couldn't help certain thoughts from entering his head, about how to use his powers in less... selfless ways.

He closed his eyes, trying to will those thoughts away, unsuccessfully. It was true that anything he changed, he could change back. And was it really taking advantage of anyone if they wanted it to happen, which he could make sure of? He found that no matter how hard he tried, he couldn't escape one conclusion.

He wanted to do it. He had the power to do it.

Harry was in control. Undoubtedly. Whatever the limits of his power, he definitely had complete control over Hermione. He could mould her into anything he wanted. And he knew he was a good person. He wasn't going to hurt her in any way. He would never do that. So, how bad could it be?

Opening his eyes again, Harry saw Hermione standing in front of him, waiting for his next command. She hadn't moved an inch, following Harry's command without question. Harry felt something harden in his trousers at that realisation. She was his, to do whatever he wanted with.

"Hermione," he began...
