Flashback
Broom Closet
Hermione stared up at Lucifer, slightly breathless from being startled and dragged to a new location, instead of the Great Hall for breakfast.
His hair fell in a curtain around his face as he leaned over her.
Only the inky shine of his eyes could be seen in his wand light, telling how dark it was being here, even in the morning.
"Turn around," Lucifer growled. "Hands on the wall." Pushing her robes to the side with one arm, he slid his hands up the backs of her legs and under her skirt.
Smoothing his hands over her injured bum, Lucifer let out a ragged breath in her ear. "Granger, where are your knickers?"
Hermione shivered. "Thought they'd just get in the way," she whispered.
"How very practical of you." Getting down on one knee behind her, he lifted her skirt and held up his wand so he could see.
Her bum looked sore and red. Deep maroon lines criss-crossed her pale skin.
"Did you hit yourself in the bathroom?"
The dragon's head glinted out at him from between her cheeks.
Lucifer smirked. "You don't get extra-credit, you know."
"I like being hit," she said simply.
'I know you do, pet."
Lucifer bent closer and kissed the curve of her arse, his lips running over the ridges left by her wooden scale.
Hermione gasped at the feel of his mouth on her sore flesh.
Pressing one finger against the jewel, Lucifer wiggled it inside her, stirring it between her abused globes.
The stone wall absorbed her hiss. "Did you touch yourself like I told you to?"
"Y-Yes, sir."
His finger slid lower, past her entrance. "Then why aren't you wetter?" 'She's barely damp.'
"You said to touch myself when I put it in, sir. That's what I did including beating my arse raw."
Lucifer understood. She'd done as little as possible, taking his words literally.
"You didn't disobey me, pet. But I think you know very well that's not what I wanted. From now on, you are to play with your clit until you are on the edge. And I mean one second away from coming. Is that clear?"
"Yes, sir."
"Good. Turn around."
Pressing her back to the wall, Hermione panted down at his kneeling body.
Lucifer looked her up and down, quirking one eyebrow. "What have you done to your clothes?"
She gave his wicked leer a smile of her own. "Just thought you deserved a nice memorable view in so many classes we have."
Lip twitching, Lucifer rubbed his chin to hide the grin that threatened to emerge.
He knew what she was trying to do. If she wanted to be a prick-tease, he'd just have to show her the consequences.
Holding his eye, she slid up her skirt until her pussy was revealed.
Lucifer kept his face blank but raised his eyebrow critically. "Is there something you'd like, Hermione?"
Licking her lips, she squirmed against the wall. "Yes, sir."
"What could it possibly be?"
"Please eat my pussy, sir," she whispered.
He smirked. "As you wish, pet."
Shocked that he'd agreed so quickly, Hermione fought to keep quiet as his tongue plundered her Galleon.
He held her upright while her hands scrabbled along the wall, searching for a hold.
Trying to stay silent, she panted at the feel of his wet, hot tongue circling and nuzzling her clit.
Small little whines kept sneaking out of her mouth, and she pursed her lips to muzzle herself.
He went on and on, teasing her with rhythmic licks until her head spun.
Her hands tangled in his hair, rubbing his scalp.
Lucifer waited for her to start humping his face then he sucked her clit between his lips.
Her strangled moan cut off mid-"unh."
Letting go of her hip, he put one finger up her slick passage, pumping in and out.
"Is this what you wanted?" he purred against her.
"Yes, sir!" she breathed back.
"Good, because it's all you're getting." He abruptly pulled away.
Hermione looked down at him with an indignant glare.
"But," she sputtered, "you . . . you just . . ."
Lucifer stood and leaned over her. "Yes. Did you not enjoy it?"
Looking furious and needy, Hermione hissed back, "Yes, of course I enjoyed it."
His middle finger slid through her folds, lightly teasing.
Fuming inwardly, Hermione's eyes went towards his neck, and she launched a feral attack.
Chomp! Duh!

Present
Empty Classroom
"Hurry up, we have Muggle Studies to go to, right?" Lucifer drawled, with quite an annoyed expression on his face.
Opening his trousers, Hermione found herself getting excited by the sight of his hard cock springing free.
'Damn.' She wanted to bite him—lull him into an orgasm and then bite him right as he came.
Lucifer saw her perverted intentions, he narrowed his eyes at her, "I am not in the mood for this right now, can you please hurry up?"
Letting the thoughts of doing him bodily harm fade away, Hermione reached out and wrapped her fingers around his shaft.
It practically burned her hand.
She leaned forward, sucking him between her lips, then proceeded to give him the most lackluster blowjob she could.
Payback for both the early morning, and damaging pillar in the class, he shouldn't have done that.
Eyes fuming, Lucifer leaned over her, resting his hands against the wall.
'Still so headstrong. When will she learn?' "I know you can do better than that, Granger."
Hermione glared up at him, at least she was doing her job of calming him down like a nice girlfriend should.
Lucifer warned her a final time, if she didn't even try doing it correctly, then what's the reason for not just using Time-tuner and going back,"You'll be sorry if you don't start putting some effort in this right now, girl."
In response, her tongue weakly flicked him a few times as she bobbed her head.
"You were warned," he rumbled darkly.
He grabbed her head and started pumping into her mouth.
Hermione tried to jerk away, but he held her firmly in place. Huffing in indignation, she gave up and let him fuck her face.
His dick now hit so deep back of her throat every few thrusts, Hermione's neck almost bulging, Lucifer could even see his dick moving inside her.
She swallowed his cock to the root like her mouth is just a black hole, burying her nose in his pubic hair.
"GLURCK! GLURCK! GLURCK!"
Hermione had long since trained her gag reflex away, but the exaggerated sounds she made when she deepthroated him turned, Lucifer on more than he cared to admit.
He slightly wondered if her anatomy is left different after the incident of Polyjuice.
Tears welled in her eyes. He'd turned her into just another hole to fuck.
That wasn't what she wanted. She wanted to make him come.
"Are you ready to suck me for real now?" Lucifer asked after a minute.
"MmmMm," she affirmed around him, jaw slightly pained from how thick his dick was.
"Show me what you can do."
Her lips were raw, and Hermione sat back for a second to catch her breath.
"You'd better make this good, young lady, because right now I'm planning on paddling your bum black and blue at night."
He didn't have to threaten her, she already felt she had let him down.
Hermione wanted him to want her, not use her.
Angry at herself for wanting to please him despite his rough handling, her brain argued with itself.
She had a sick need to prove she was the best, that he could never just dismiss her as another mouth to fill.
Lucifer watched her stare at the floor as she tried to pull herself together.
Hermione took a deep breath and looked up at him; her eyes shone on the verge of tears.
He remained stoic but felt his heart lurch when she spoke.
"I'm sorry, sir. I want to make you happy. I was just upset, you didn't listen to me in the class. I'll do better now."
She maintained eye contact so he could easily look into her head.
Lucifer found her repentance genuine and nodded at her, his own anger now subsiding.
