Summary
Draco makes Hermione become his sex slave due to and unbreakable vow

Hermione reluctantly stepped up to Draco’s front door, he’d asked her to come round for some reason, she almost didn’t come but she was too curious for her own good. She hesitantly opened the door and was drawn into a dark, vast open hallway. “Draco?” She called out apprehensively.

“In here Hermione.” Replied Draco. The shy girl walked into a lavish living room with a blazing, lit fire and Draco sat in a green velvet chair, looking malicious and sly. He stood up and pointed his wand directly at her and hissed the word “Imperio!”. A blinding light had overwhelmed her vision; then everything went dark.

When she woke up, it all came back to her. Draco had cast the imperious spell on her, he’d got her to hold his hand and make an unbreakable vow with his father, Lucius, as a witness.

 

“Do you Hermione, take Draco to be your master and owner and do any task he requests no matter what it is?”

 

“I do” she said although her mind was screaming no.

 

“And do your Draco take Hermione to be your slave for both personal and sexual desire?”

 

“I do.” Said Draco with a wicked grin beneath his devilish eyes.

No no no, they had tricked her into making an unbreakable vow, her head was spinning as her eyes welled with tears. Draco entered the room, she must still be in his house, and he must have stripped her in the night. “Oh don’t cry Hermione, it won’t be that bad.”

 

“Fuck you.” Screamed Hermione through her tears, there was no way out of this, unbreakable vows were permanent until death. Her life was over.

 

“Don’t talk to me like that, bitch! I wouldn’t want to punish you so early now would I?”

 

“Punish me?”

 

“Yes, however I please, now you must always call me master from now on. You must be polite, obedient and do whatever I say, weather we’re with company or not, there is no need to be shy anymore, soon enough everyone at Hogwarts will have seen me fuck you; your’re mine now you slut.”

 

“I will never call you master!” Cried Hermione, “and I will never have sex with you.”

 

“Well, if it takes a bit of punishment to get you too obay, that will be fun, but we both know you can’t resist in the long term; after all you're too pretty to die.” Said Draco softly as he grabbed her by the hair and threw her over his lap with her ass raised in the air, before she could even process what was happening his hand came down hard against her ass, leaving a stinging red handprint. She tried to struggle and to get away but she was stopped by three hard spanks in quick succession. “A good spanking should put you in your place. You will count each one and say thank you master afterwards, if you refuse to count or thank me I’ll start over from one.” He snarled before spanking her left ass cheek.

But Hermione refused to speak, Draco did not like that. He went berserk, switching between her left and right cheek with constant spanks without hesitation. After what felt like an eternity of agony, Hermione burst into tears, Draco pulled her head up by her hair and whispered in her ear through gritted teeth, “Are you ready to be a good girl now?” Hermione nodded, trembling. Draco wiped the tears from her cheek. “Good, now let’s continue.”

He did one spank to her left cheek and paused waiting for Hermione to speak, which was hard due to the lump in her throat. “One, t-t-t-thank you.” Draco stared at Hermione with a stern look, “Aren’t you forgetting something?” muttered Draco, there was a long pause, “Master.” sobbed Hermione.

“That’s better.” Whispered Draco. In an instant, another hit struck down onto her right cheek, “Two, thank you master.” He continued switching between each cheek and waiting for her to thank him. Hermione noticed he liked how her ass jiggled after each hit due to his mesmerised expression. After the first ten spanks he rubbed her ass, it was painful and no doubt covered in red handprints- and would definitely bruise.

 

He then did ten to her left thigh, it was somehow more painful than her ass. Then he moved and did ten on her right thigh. Hermione was struggling to reply after each strike now. “Last ten baby” he whispered before spreading her legs and landing the hardest one yet right on her tight pussy.

 

“Forty, thank you master” she said as his hand slid down to her tired pussy, and massaged between her folds, “Ooh you're all wet, Granger, I bet you liked it you filthy little mud blood.” Draco snarled, He began to rub her clit to get her all riled up before sliding his finger into her sore pussy; he began to finger her slowly. Hermione tried to bite her lips and not moan, she didn’t want him to have the satisfaction, but she couldn't help but to let out a little moan as he plugged a second finger in and pumped harder. “Don’t try to stop the moans Granger, I want to hear them.” His thumb started rubbing her cliterous, and built her up right to the edge before stopping and pulling his fingers out so her only stimulation was the rubbing of her clit, she had been so close to cumming. “If you want to cum, Granger, all you have to do is ask me nicely.” He said as he smirked, rubbing harder so she was getting closer. She didn’t want to but after being built up for so long she was desperate. “Please! Let me orgasm?” She begged. The desperation in her voice showing

“Please who?” He added.

“Please, Master.” She whispered, full of shame.

 

He picked her up and threw her onto his silky bed sheets which were draped across the bed.

“Hands and knees. Now Mudblood!” With no choice, and tears staining her face, she got onto her hands and knees. Draco got up behind her and grabbed her waist before pulling down his trousers and plunging his dick into her wet hole. “Gosh you're nice and tight Granger, though I didn’t expect much from a mud blood like you.”

 

He continued to pump his throbbing dick in and out of her, he reached around and rubbed her clit until she came. But he wasn’t finished so he continued to harshly thrust in and out of her until he came right inside of her. Cum dribbles down Hermione’s leg and onto the bed sheets.

 

Exhausted they fell down onto the bed, panting. “You can take a potion in the morning, for now get some sleep, after all we have to catch the Hogwarts express in a week.” He said as he reached round to cuddle Hermione but she didn’t feel safe, she felt confined, trapped. It dawned on her what she had just done and she was filled with regret and shame. What would everyone at Hogwarts think of her, he wouldn’t really make her do things in public would he?
