Again in the library

Hermione needed something to focus on.
Something to distract her from all that talking about her streaking.
She couldn't believe that even after two weeks people still occasionally mention it.
Not like they knew it was her.
But it still took her by surprise when she was walking next to someone and they would describe what they would do to that naughty streaker.
Some descriptions were mundane, however some of her fellow students have really exotic ideas.
Some of them make her even blush.
To avoid people as múch as possible, she spent lots of time in the library, trying to find some information about magical tattoos.
So she could remove that one of her butt.
So far, she hasn't been successful.
Partially because of Emily.
It was difficult to focus on the books. When she constantly tried to play with Hermione's body.
Or took her cloak and hid it, so Hermione would be **** to spend time in the library naked.
Which led to several close calls with other students.
Which makes her extremely horny.
And Emily of course took advantage of the situation.
It was evening, shortly after the library closed and Madam Pince checked if some students didn't stay behind.
Hermione and Emily were hiding in one of the smaller study rooms.
Behind the privacy charm.
During their study session, Emily spent her time mercilessly teasing Hermione.
Starting with gentle kisses on her neck, and as she moved down Emily started removing Hermione's clothes.
Which wasn't difficult at all, because she was wearing only a cloak.
Usually buttoned to the top.
But when they were alone she kept it open.
Showing her cleavage, flat stomach and her shawed crotch.
With every step she did the cloak opened more and more.
Showing her legs.
As Emily continued disrobing Hermione, the Gryffindor girl tried to read some old book.
The table before her was covered with books and scrolls.
In one moment, Hermione reached for one particular scroll on the opposite site of the table.
To better reach it, Hermione kneeled on the chair and leaned over the table.
As she did it, Emily took the opportunity to take Hermione's cloak off completely.
Hermione froze for a second, kneeling on her chair and reaching over the table.
She gave Emily an incredible view at her butt.
“Are you done?” Hermione asked, annoyed, looking over her shoulder.
But she didn't move to cover herself.
Emily smiled and dropped Hermione's cloak on the floor.
“I am only starting.” She said and put her hands on Hermione's hips.
“I love striping you, shame you are wearing so little these days.”
Hermione arched her back.
“Do you want me to start wearing clothes again?”
Emily playfully patted Hermione's butt.
“Don't you dare, I love you like this even more. I thought, maybe some accessories.” She said and started fondling Hermione's buttcheeks.
Especially the place where that magical tattoo appeared.
“Accessories??” asked Hermione and pushed her butt into Emily's hands.
“Something to match your slutier site.”
Emily explained and slapped Hermione's left buttcheek this time stronger.
Hermione yelped and Emily watched with glee as a tattoo appeared on Hermione's buttcheek.
Clear sign that the Gryffindor girl is enjoying the situation.
“You are incredible.” Emily said and spanked her again.
This time stronger in an attempt to add red palm print over the SLUT tattoo.
Hermione bit her lips and whimpered.
Still leaned over the table she was in a perfect position for a spanking.
“Continue, please." Hermione pleaded.
“Does my naughty girl want spanking?” Asked Emily and delivered another slap on Hermione's butt.
“Or does she want the accessories?”
Hermione thinked about it for a moment, wiggling her butt and arching her back.
Hoping she could bait Emily to do both.
However it seems as if Emily was reading her mind because she said.
“You need to choose or you don't get either.”
“Accessories, “ gasped Hermione,” I want Accessories.”
Emily leaned over her and kissed her on the back and then on the neck.
Hermione enjoyed the kisses, until she felt something enveloping her neck.
The feeling reminded her of her night adventure with the mistress.
She didn't need to check Hermione was sure Emily just put a collar on her.
Then she noticed leather on her wrist and when she looked at her feet similar leather ware on her ankles too.
“Stand up!” Emily commanded.
When she did the leather cuffs on her wrist were pulled to the collar.
Hermione tried to pull her hands down but she couldn't.
She tried to take a step forward but she almost fell.
Her ankles were bound to.
The invisible chain allowed her very small steps.
Emily watched as Hermione tried her bonds trying to understand how restricted she was.
“What now?” Hermione asked quietly. Looking at Emily.
“Just a few things. First.” Emily said and waved her wand.
Blindfolded appeared around Hermione's eyes.
Surprised, she took a step back and almost fell again.
Forgetting about her shackled feet.
But Emily was able to catch her.
“Carefully.” She cooed into Hermione's ear.
Hermione nodded, she realized the blindfold was partially see through.
It was like looking through a net with really small holes.
She could still see basic shapes but details were blurred.
She saw the library shelf in front of her but she couldn't recognize any book on the shelves.
“What are you planning with me?”
“Just a game.” Emily said, still really close to Hermione's ear.
“But first we need to add one more thing.”
Hermione wanted to ask what, but before she had a chance, Emily touched her pussy with her wand.
Hermione freezes as the wooden tip gently glides over her slit.
“Done.” Emily said and took a step away.
She must cast it nonverbally though Hermione.
“What did you do?” she asked but instead of Emily answering Hermione felt it.
Someon, no something started to play with her wet pussy.
She moaned when the spell gently started to bring her to orgasm.
But before she could climax it stopped.
“Pleas.” She beged.
“We are gonna play a game.” Emily's voice echoed from a far.
Hermione turned her head trying to see through the blindfold.
All she could recognize was a silhouette of Emily standing in the door of the study room.
“Game?”
“I am going to leave," Emily started to explain. “With your cloak and wand, of course.”
“You can't leave me here like this.” Hermione protested with a hint of a fear in her voice.
She tried to take a step to the door.
Immediately the spell started to finger her.
“Gods.” She gasped as her legs trembled.
“I can and I will,” Emily continued.
“I will wait for you outside. Don't worry my spell will guide you. Every time you take a step in the right direction it will stimulate that lovely pussy of yours.”
“Please, what if someone sees me?”
“In that case they will see one naughty witch enjoying some kinky game.”
“Butt..” Hermione wanted to object, however, Emily had enough.
And with the wave of the wand, gag appeared in Hermione's mouth.
“Emhy..plahe”
Hermione tried to speak.
“Don't let me wait too long. Or...” Emily didn't finish, Hermione quickly started to walk to the door.
Hoping to see where Emily goes.
But when the bound Gryffindor reached the hallway.
It was empty, as far as Hermione could see through the blindfold.
She continued to take small steps, and immediately she felt a gentle vibration in her wet pussy.
“Hmmmh..” she moaned through the gag.
At least she chose the right direction.
The spell brought her closer to the climax with every step she did.
When suddenly it stopped.
Hermione stopped too, she was breathing heavily.
As she was almost over the edge.
She turned around and the spell started again.
She didn't notice the corridor on the left.
Hermione started to approach it, the spell intensity increased as she did.
Sing that she is on the right path.
As she approached the corner she was again almost on the edge.
One more step and she will have a orgasme.
Hermione whimpered and prepared for the next step.
But before she could do it someone came from behind the corner.
She stood so close that the person bumped into her.
Her hands bound to her collar came into contact with someone's chest and she instinctively grabbed the person's clothes.
She felt strong hands on her shoulder as the person instinctively grabbed her too.
“Whoa!!” A surprised male voice filled the air.
She recognized that voice immediately.
In an attempt to hide her identity she pressed her face into his chest.
But it was pointless.
The boy recognized her and with his hands still holding her naked shoulders Neville gasped.
“Hermione!?”
