« My (bitter)sweet Granger,

I would like to thank you for your help last night. I owe you one. Could you come down to the Slytherin common room tonight?

Can't wait.

Pansy »

Hermione read the message one more time, took a deep breath, and knocked on the stone wall she knew was the entrance to the Slytherin common room.

« They cannot hear you » she heard behind her.

It was Scarlett, again.

The Slytherin smiled, in a strangely warm fashion, and walked to her. There, she grabbed her by the neck and softly pressed her mouth on Hermione's.

Hermione was caught off guard, but was surprised to find out that she was pleased. She only realized at that moment that none of the Slytherin girls had ever actually kissed her. She pressed her body against Scarlett's.

The Slytherin's tongue snaked inside Hermione's mouth.

The two girls moaned, and then suddenly the stone wall moved and Bella's figure appeared behind it.

« There you are, Granger! Getting groped, as usual! Please come in, be our guest »

Hermione came back to her senses. She knew Bella had seen her in way more compromising positions, yet this kiss with Scarlett had felt so private she was embarrassed.

She stepped inside the gloomy room.

Pansy was sitting on a big armchair by the fireplace.

« Hello, Hermione» she simply said. « I see you have come for your reward. »

« For her treat » added Scarlett.

Pansy and Bella laughed.

« Considering what I know of your tastes, I am sure you are going to love it » smiled Pansy.

Hermione felt herself cream. She had accepted the fact that she liked to be used as a toy by these girls, and she had been excited all evening to discover what they had planned.

« I'm sure I will take it with great pleasure » she said.

« Good lord, Granger! You are almost turning me on! Is that the kind of talk you used on Snape yesterday? He got back reaaally late » Pansy said, laughing.

« Oh yes, tell us about it, Granger, tell us what he did to you » asked Bella eagerly.

« Well, we kind of talked… » started Hermione.

« You didn't have sex with him, did you? » asked Scarlett uncomfortably.

« No, no, I didn't. He just looked and… »

Pansy didn't say anything, but Hermione could tell that she was a little disappointed.

« Did he look at your pussy? » asked Bella.

« I… I guess »

« Oh, were you shy, Granger? You are always so willing to show us your little cunt. »

Scarlett walked behind her and wrapped her in her arms, caressing her lower belly down to her pussy.

« She is, isn't she? You are a good girl, Hermione, I am glad Snape didn't spoil you for us »

« Is that it? Nothing else happened ? » asked Bella.

« He just… he just wanted my panties » blushed the Gryffindor.

The three Slytherin burst out laughing.

« I am sure he doesn't regret that, she was all wet and ready last night » said Scarlett.

« Did you make her squirm like a little dog, Scarlett? » inquired Pansy.

« I did »

Scarlett moaned at the memory as her hands roamed everywhere on Hermione's body, whose eyes were now closed.

« I'm doing it right now »

« Speaking of dog… what about the treat?! » exclaimed Bella.

« You're right, the treat… » Pansy smiled. « Look at me, Granger! »

Pansy got up from her chair and walked to Hermione, who was now caught between Scarlett and her.

She whispered to her.

« Are you wet, Granger?»

She kissed the Gryffindor's neck softly.

« Yes.. » breathed out Hermione.

« Would you show me how wet you are? »

The Gryffindor pulled her wand out of her robes and flicked it. Her clothes disappeared. She dropped her wand on the floor and spread her legs a little.

Hermione could hear Scarlett breathing hard behind her.

« Look. »

Pansy slapped her bare pussy. Hermione gasped.

« Do you expect me to get down on my knees, slut? »

The Gryffindor went to the armchair and sat on it, her legs wide open, exposing her burning pussy.

« Always so leaky, that one » commented Bella.

The three girls surrounded Hermione. They all looked eagerly at her cunt pulsating and dripping on the carpeted armchair. She loved it, she loved watching the horniness and desire of those three girls devour them from inside as they were about to make their move and fuck her.

« Treat me » she said.

They all smiled.

« You helped the Slytherin house pull a great stunt last night, Hermione. We want to thank you. »

Hermione heard footsteps coming from the stairs. Straps appeared from nowhere and circled her wrists, tying her to the armchair.

« We all want to thank you »
