Yes, as quick as she can

Hermione clasped her hands over her privates as she made her way through the corridors of Hogwarts.

She was lucky that most of the portraits in the castle had been taken to Filch's office for cleaning. "Hang on..." Hermione thought to herself. "If Filch is out of commission, then the paintings won't be back up until he's feeling better..."

Hermione looked around. The only noises heard was that of the wind outside. She slowly lowered her arms to her sides, exposing herself entirely, throwing caution to the wind. She looked down at her body and softly giggled.

She may not have wanted the Slytherin girls to be the ones to make her expose herself, but she was actually enjoying herself. She, former head girl, top of the class, rule-following Hermione, was utterly naked where she shouldn't be.

Hermione felt incredibly naughty as her hand drifted to her snatch...

But she caught herself. This wasn't the place to be caught, even if the only ones roaming the castle now were the Slytherins, Peeves, and McGonagall. Even Hagrid was still at the castle, though she didn't know how often he'd come in if he was worried about catching scrofungulus. There really was nobody to see, or help her, out of her predicament.

Fluid steadily dripped down her thighs as she walked, not bothering to cover herself, to her dormitory.

Since Hermione wasn't holding them, she could feel her B cup breasts slightly jiggle with each step. Cold drafts flowed around her and between her legs. Her nipples perked up, as hard as they could go. The wetness made her pussy feel even colder. This heightened feeling of exposure turned her on more and more as she made her way through the quiet castle.

When she saw the portrait in front of Gryffindor tower, she froze. The Fat Lady was gone!

The frame was still there, but it looked like the Fat Lady had left!

Hermione looked around, but there were no other portraits. She thought about calling out to her, but then she realized something. In all her years at Hogwarts... She had never learned the Fat Lady's name. Hermione didn't want to just yell out 'Hey, Fat Lady, can you come back?'

"I may be nude," Hermione thought to herself, "but I shall not be rude!"

There was no point waiting here for the Fat Lady to come back. Hermione made her way to a nearby classroom. Since classes were out, she thought, there wouldn't be anyone to stumble upon her while she was naked.

Hermione recognized this room as the arithmancy classroom, where she had spent a good portion of her time studying. In fact...

Hermione made her way to a bookshelf and saw all the necessary information was on it. She could spend a while in here writing her Arithmancy essay. "At least this wasn't a complete waste of time," Hermione thought.

Hermione grabbed some parchment and quills, as well as the books she'd need, and as down to write, but even doing homework was more pleasurable than it had ever been before.

She felt the polished wood of her seat cold against her bum slowly warm up from her own body heat. As she wrote, she felt what little fat there was on her arms jiggle, her elbows knocking into her jest.

Every movement she made as she did her homework only served to arouse her more and more. When she was about three-quarters through her essay, she couldn't take it anymore.

Hermione got up and went to the teacher's desk. She sat on it, spreading her legs wide so that her feet were touching the corners of the desk. As she touched herself, she began to imagine the room, filled with students, all looking at her. Some admiring her, some jeering at her.

Hermione picked up the pace, fingers going in and out of her pussy as she thumbed her clitoris. She imagined a faceless teacher advising students on how to use magic for pleasure, using Hermione as an example.

In a matter of minutes, she came, her juices squirting so far that they even touched the edges of the desks in the front!

After Hermione caught her breath, she grabbed some old, scrap parchment and used it to sop up the mess before throwing the parchment into a nearby fire.

She returned to her essay. Once she was satisfied, she put everything back where she found it, grabbed her homework, and went to see if the Fat Lady was back.
