Hermione bit her lip as she walked. She hated the fifth floor corridors at night, they were so dark and only a few sconce's were lit, sometimes you could be walking for minutes in darkness so profound it pressed in on your eyes, normally she would light her wand, but she couldn't manage to hold it along with all the books and equipment she was carrying.

She hurried along holding her books to her chest, her footsteps echoing through the deserted corridors. A flicker of movement past a window caught her eye, she stopped and held her breath listening with all her might, she heard nothing but quiet noise from outside and the odd creak and rustle, usual sounds to be heard at this time in Hogwarts.

She pressed on, walking a little faster now. She turned a corner and could see at the end of the corridor the Fat Lady's portrait, she breathed a sigh of relief and slowed down. Suddenly behind her she heard a deep crackling voice say.

"Obscuro".

A blindfold appeared and wrapped itself around Hermione's head, she shrieked and dropping everything she was carrying. She went for her wand, before she could reach it she heard.

"Incarcerous, Muffliato".

Hermione felt ropes tying her arms behind her back and her ankles causing her to topple forwards, hands grabbed her before she hit the floor and lowered her down.

"Scream all you want", said the voice, "no one will hear you".

Hermione's heart was beating fast, she couldn't see who her attacker was but she thought she recognised his voice.

"Whoever you are just leave me alone, I'll give you anything you want, just untie me, I won't tell anyone, I swear".

"I'm going to get exactly what I want if you like it or not, slut, and you still won't tell anyone".

The ropes around Hermione's wrists restricted and loosened, changing her position until she was kneeling her head tilted back.

"Diffindo".

Hermione's clothes fell off around her leaving her naked and cold on the floor. Her nipples stiffened from the change in temperature. The man grabbed her head roughly and stood before her with his hard cock directly in front of her mouth.

"Open wide whore".

"No...!"

Hermione tried to scream but as she opened her mouth he rammed his cock in, gagging and choking her as he forced it to the back of her throat. Tears streamed down Hermione's face as she stared up at where her assailants face should be, he must have been using a concealment charm because all she could she was a dark shadow.

The man's thrusting because faster, Hermione knew what was coming she looked up at her attacker with pleading eyes, hoping he would stop. Suddenly he pulled his cock out of her mouth and Hermione gasped, just as quickly thick streams of cum shot from the end of his cock landing on her face and in her mouth, he grabbed her chin and held her mouth shut.

"Swallow it you dirty slut".

With no other options Hermione did as she was ordered and swallowed the cum in her mouth, something which she normally enjoyed tasted bitter and wrong in her mouth and she felt it slide down her throat. The man flicked his wand and the ropes again restricted and loosened until her cum spattered face was on the floor and her ass was in the air, she whimpered knowing what he would do next.

"You have a fucking gorgeous ass, I'm going to fuck you now, whore, and you are going to love it".

He stroked up the inside of her thighs, over her ass and up her back then back down again, as he reached her ass he stroked and squeezed each of her cheeks, pulling her cheeks apart and letting them fall back again. A moan escaped her. she was shocked, she couldn't believe what she had just done.

"I told you, you would like it". The man sneered behind her.

His hand slipped under her and began to caress her wet pussy. She moaned again. She couldn't understand how this could be turning her on, she felt dirty and used, but at the same time she wanted him to fuck her, take her hard in any way he wanted while she lay helplessly covered in his cum on the floor.

"Just fucking do it you scum, you know you want it so just take it".

She gasped as he slid a finger into her.

"You're so wet". He said as he slid his finger in and out of her slowly, torturing her.

Hermione pushed her hips back as much as she could, moaning and biting her lips. She heard her assailant move behind her, he deftly pulled out his fingers and replaced them with his cock, pressing the tip tantalisingly into her entryway.

"Fuck me, please" she whispered.

"What was that slut?"

"I said, Fuck me please" she said again, louder this time.

"Not just yet", he cooed from behind her.

A smack seemed to echo through the halls as he slapped her hard on her ass, she gasped, enjoying the feeling of his fingers teasing her and the pain on her ass. He continued slapping her ass taking each cheek in turn getting gradually harder until she knew her ass must be practically glowing.

"Please stop and just fuck me!" she shouted at the top of her voice, not being able to take any more, her inner thighs were now wet and her pussy was practically dripping.

"Your wish is my command" he said as he rammed his cock into her not stopping until his groin smacked into her ass.

She yelped at the sudden feeling of being filled and her sore cheeks being hit, but as his rough thrusting continued she began to moan.

"Yes, that's it", she moaned, "fuck this dirty little slut".

As if goaded on by her, he began pulling out nearly fully then slamming back into her, over and over again, her yelps would have woken half the castle if it wasn't for the muffliato charm, he could do this to her all night and not a person in the castle would hear them.

After ten minutes of being roughly fucked Hermione could feel her orgasm building, filling her, she tried to hold it back but knew there was no stopping it now, the combination of the fucking and the her sore ass being continually smacked into was too much to bear, with one hard thrust her attacker brought her over the edge and she screamed with her orgasm rushing through her body.

"You dirty whore, I'm going to cum inside you".

She felt his thrusting pattern change to a more frenzied one, and with another hard thrust he slammed into her and held himself there, she could feel him cumming inside her, filling her and making her feel dirty.

After holding himself there for only a few moments he pulled himself out and stood over her.

"You are a dirty little whore whose only use is to pleasure better men".

He moved around behind her again.

"Flagarate".

She yelped as she felt a burning sensation on her already sore ass.

"That will remind you of our little encounter, it will fade, eventually, Dissendo".

The ropes fell from around Hermione and instantly she began to stand.

"Stop, if you stand I will tie you up again and leave you here for the next person to find".

She stopped half crouched.

"You will stay as you are for thirty seconds, then you may leave, do you understand".

"Yes", she said through gritted teeth.

"Good".

She heard him walking away.

"You never know, we may yet have another encounter, Miss Granger". He called back as he walked.

After waiting the thirty seconds Hermione stood and after finding her wand in the pile of rags that was her clothes she said.

"Reparo".

Her skirt and cardigan knitted themselves back together, the rest of her clothes her damaged beyond repair. She pulled on her skirt and buttoned up her cardigan as best she could to try hide her nudity and using a large scrap of what was her blouse she wiped the cum from her face, collecting her things she made her way back to her dorm.

Back in her room she changed out of her skirt and cardigan and looking in a mirror she could just see in the dim light of the dorm the letters 'C C' burnt into the right cheek of her ass. She clambered into bed trying not to wake her room mates and laid on her side. It would be quite a few days until she could lie on her back again, and classes tomorrow were going to be murder.
