Her deepest heart's desire

Hermione dropped the broom to her side as looked in horror as she saw herself, dressed as she was. There was the magical lead coming from her collar, but the person holding it was out of sight, hidden amongst the silhouettes of dozens of people surrounding her. She saw her magical vibrator was in her pussy at the same time, and even though she showed embarrassment on her face, she was flaunting everything she had.

"No... NO!" She fell to the ground on her hands and knees. She didn't feel a longing for what was in the mirror... At least when Harry and Dumbledore had looked into the mirror, they saw things that were not possible, but this? It could very well be reality. It was a very likely possibility that it could be reality! And yet she knew that what she saw was something she wanted greatly...

As she looked at her humiliation in the mirror, she couldn't help but be turned on. Her head got fuzzy and couldn't think straight. She knew of only one way to clear her mind at this moment with what she had on hand. She positioned herself in front of the mirror, sitting with her legs spread. With one hand behind her back to support herself, she began to play with her pussy.

She looked on as the version of herself in the mirror was getting orgasm after orgasm, absolutely loving the attention even if she was absolutely humiliated by it. The very idea of this reality turned Hermione on, thrilling her to a point where her juices were oozing onto the stone floor.

She increased the pace of her masturbation as her reflection kept moving her hands, ostensibly not knowing which way to cover herself, but in reality, it was to grope her breasts, pet her pussy, and play with her arse.

After a short while, both her and her reflection came at the same time. Hermione's juices splattered onto the bottom of the mirror. She fell to the floor, looking at the high ceiling of the chamber.

What could she do? This was what she wanted, wasn't it? Deepest in her heart? Does that mean that Ginny wouldn't bring her the robes? What could she do? Was there a way to make sure that this would work?

Then, Hermione had an idea. An idea to make sure this would work, but she had to ask Dumbledore a question first about the spell of protection...

After she had used the broom to fly through the chambers and out of the trap door, she decided to take a shortcut this time to get to the quidditch pitch by flying through an open window that would be out of view from the Hospital wing. After returning the broom to its cupboard, she sprinted back to the castle, the excitement of streaking across the grounds filling her once more.

She was panting by the time she made it to Dumbledore's portrait. "P-professor!" Hermione panted.

Dumbledore came back into view. "Hermione, you look exhausted. I take it you saw the Mirror of Erised? And what did you see?"

"I didn't see what I'd hoped... But-"

"I figured as much..." Dumbledore nodded solemnly. "It is very easy to see what we want, even things that are very possible... There was a time I saw something else in the mirror, you know, something I could have had, but I fought against it. I know you can too, Hermione."

Hermione, somewhat annoyed at Dumbledore's interruption, carried on. "I'm trying to fight against what I saw, Professor! I'll wait for Ginny's response before doing anything, but I have to know. The protection lasted when I left Hogwarts grounds and entered the village proper, right?"

Dumbledore looked taken aback. "The protection would not work outside the grounds, but it would resume once you returned, yes."

"Can I apparate if need be?"

Dumbledore was even more nonplussed. "You would leave the grounds and the school as you are, to return later?"

"Yes!" Hermione pressed. "If my message to Ginny was messed up, I might be able to try to talk to her alo-"

"There you are, mudblood!"

Hermione spun around to see Millicent, angry. "We told you to be with us at all meals! You're late for lunch! You're going to be sorry for this, you little slag!"

As Millicent reached with her ring hand to summon the lead, Hermione looked to Dumbledore's painting, but he had already gone, evidently not wanting the Slytherins to know that he was helping her.

Millicent then yanked on the lead, practically dragging the nude Hermione to the great hall.
