Naked under the cloak part.2

As Hermione walked between the bookshelves, she stopped to be cautious.
Not as if she exposed herself willingly, but she felt more safe here, so she didn't try to adjust the cloak that much.
Still carrying the book, most of her body was covered.
If she met someone, they would see only her legs and bare feet.
Thinking about it, she didn't pay attention to where she was going.
And when she turned around the corner she collided with someone.
She heard books falling on the ground.
Reflex caused her to hold her book tighter which caused the book to move slightly higher.
As a result her pussy was now uncovered. She could feel it.
“Sorry I didn't see where I was going,” said the boy she collided with.
“Are you all right?” He asked.
Hermione looked at him based on his uniform; he was from Hufflepuff.
Hermione nodded.
The boy started to collect his books.
To do it he must kneel in front of her.
Which will put him in direct eye level with her bare pussy.
When she realized it she froze, incapable of moving or running.
She was waiting on his reaction.
“I just collect these,” he started saying then he stopped.
Hermione felt his breath on her exposed lower lips.
The boy froze in shock, before him was a beautiful glistening pussy. He could only stare at it.
His breath started to have an effect on Hermione.
Goosbump run over her spine, not waiting any longer, Hermione started running.
In proces she toppled the boy and he falls on his back again.
Last thing he saw, ware pair of naked buttcheeks running away from him.
Hermione didn't look back, she just ran between the shelfs.
As far from the boy as possible.
The cloak was gliding after her. Exposing her butt.
She didn't care, right now she needed a place to hide.
Her subconscious led her into the private study room in back of the library.
Hermione collapsed into the comfy chair, the book slipped from her hand. With loud thud it landed on the flore.
The cloak opened itself as she sat, revealing her boobs, flat stomach and her glistening crotch.
Hermione was breathing heavily, after the run.
Catching her breath she sat there several minutes. Not covering herself.
If some student would enter the study room now.
First thing they would see would be one aroused and flushed witch, exposing her bare private parts.
As she was sitting there exposed. Her hand found its way to her crotch.
Hermione gasped when her fingers touched her wet lips.
She didn't realize how damp she was down there.
She must have enjoyed this way more than she was willing to admit.
Slowly massaging her pussy and with one finger she penetrated herself.
“Mmm, yes.” Hermione moaned.
She started gently fingering herself. Moaning as waves of pleasure washed over her.
For beter access she put one leg over the chair armrest.
Opening her pussy slightly more, her finger moved deeper.
“How about this one?” a sudden voice behind the door asked.
Hermione opened eyes and froze in movement.
With fear mixed with arousal shecwas watching as the door handle moved.
“Not this one.” Second voice answered.
Door handle stopped moving and the sound of footsteps vanished in the distance.
Hemrione exhaled, and put her finger out her pussy.
“That was too close.”
She colected herself and took the book. Still needing to put it back, she uses it as an excuse to delay her exhibitionist adventure.
