A/N: I was not anticipating updating this so soon, but it seems this story needs to come out so badly it's practically writing itself. Let's hope I can keep it up :)

Once again unbeta'd so please forgive my mistakes. If you notice anything glaring please point it out to me!

Ever since she had returned to her dorm Wednesday evening Hermione's mind had been spinning. She had passed right by Ginny and Neville in the common room without a word.

"That bad, huh?" Ginny had called after her.

She had replayed the events of her 'detention' over and over while laying in bed that night. She had made herself come three more times before falling into a blissfully deep sleep. She dreamt of Professor Snape filling her with his cock over and over again, sneering at her that she was a dirty dirty girl. She'd woken up sweaty and tingling with aftershocks from an orgasm in her sleep. Thankfully the 'eighth' years had their own small private rooms to sleep in, though they had to use the communal bathrooms. It cut down a lot on any explanations she'd have to give to her fellow Gryffindors.

All day Thursday Hermione walked around in a fog. She couldn't concentrate on anything. Her mind was full of Snape's dark intense gaze and long calloused fingers. She had barely taken any notes in her classes, which was unheard of for her. Thank the Gods she hadn't had potions that day, she didn't think she'd be able to face him up close and personal in front of her classmates. She had snuck a peek at him during breakfast that morning and he had glared at her like she'd stomped on his favorite crup.

Did Snape even like dogs? She found herself wondering the most ridiculous and random things about him. She realized she knew next to nothing about the man, yet she was ready to jump into bed with him.

And so what if you are, Hermione? She scolded herself. It wasn't like he had proposed marriage to her. They clearly had similar sexual tastes, and he wasn't bound to tell anyone about her proclivities, considering he'd lose his job if their activities came to light. He had made her feel things she never had with any other man (or rather, boy). Hell, he'd taken her to a place she'd never even been able to reach on her own.

So why not see where things could go? He had given her the option of whether or not to continue, so there'd probably be no hard feelings if she changed her mind at some point. It seemed like he was just in it for the sex… Surely her Professor wasn't interested in a student romantically…

Like that makes it better! Hermione, you sound crazy.

She knew a student/teacher relationship wasn't morally sound. And if she heard that any of her female friends had slept with a Professor she'd probably be alarmed. But this felt different somehow. They'd fought in a war together (sort of). She had been of age for a few years now…

Hermione knew she was just coming up with any reason to justify it to herself. But, dammit, she didn't really care one way or the other. She had spent nearly her whole adolescence helping to bring down an evil megalomaniac. She had seen death and torture, and endured torture herself. She had used unforgivables on Death Eaters in the final battle. It was about time she let go and had some fun. And if she was completely honest with herself, the taboo of it all was part of the thrill.

Severus Snape was in a good mood. For the first time in as long as he could remember he had to force himself to scowl (so as to not arise suspicion. It wouldn't do for him to walk around smiling, someone might try to commit him to the Janus Thickey Ward.)

He hadn't felt this relaxed in, well, maybe ever. He was free of his bastard father, free of the infuriating marauders, free of the two masters who had ruled his life for nearly twenty years. He had a job that he could keep if he wanted, but didn't really need. He had enough potion patents under a pseudonym to pay his bills. And now he had a randy little witch desperate to please him. What more could a man want?

As it was, Minerva still noticed something was different about him at breakfast.

"My, Severus, are you feeling quite well? It's nine am and you haven't bitten anyone's head off yet!" She called to him from two seats down at the head table. The other Professors all leaned in to see his reaction.

Snape rolled his eyes and sneered at her, "Can't a man have his coffee in peace, or must I always be performing for your amusement Minerva? As if I haven't endured enough puppet masters in my life." He glared out at the great hall.

McGonagall huffed in feigned irritation, "Put your fears to rest everyone, Severus is just fine!" She announced. There was a quiet murmur of chuckles amongst the table.

Snape's good mood dwindled as the day went on. Unfortunately he was still a professor which meant he still had to teach classrooms full of dimwits. And the image of Hermione's little pink bum wiggling around on his desk kept him so distracted his second years nearly blew up the classroom. Twice. Gods, the memory of her on her knees in front of him, eagerly reaching for his cock was etched into his brain.

Which is why he had started to doubt whether the girl would return on Friday. He was fairly certain she would- she was positively gagging for it. And she'd seemed eager enough the night before. But, he had to leave himself open to the fact that she may change her mind, lest he be too disappointed. And if life had taught Severus anything, once he had a good thing going, it was snatched away from him in short order.

It would probably be wise on her part if she stayed far away from him. But he wasn't about to tell her that.

Friday after classes he made sure he was prepared for her visit, but kept his expectations low. Severus was hoping she would show up, but he had a nice vial of dreamless sleep as a back-up plan.

When Hermione arrived at the Potions classroom on Friday evening the door swung open at her first knock. But Snape was nowhere to be found. She hesitantly crossed into the room, and called out,

"Professor Snape?... It's Hermione Granger.. I'm here for my detention sir." The classroom door clicked shut behind her and she heard him faintly respond,

"Come in, Miss Granger." His voice seemed to be coming from an open door at the back of the classroom that she had never noticed before. Hermione tentatively made her way into what was obviously his private sitting room.

Snape was leaning back on a large black armchair by the lit fireplace. He was once again free of his robes and frock coat, and this time wore a dark gray dress shirt.

"Back for more, are we?" He drawled at her with a leer, raking over her from head to toe with dark eyes. She felt distinctly like a bug under a microscope. She had considered changing out of her school uniform but ultimately decided not to. He'd seemed to enjoy it last time.

"Yes, sir, but I…. Well.." Hermione sat down primly on the edge of the chair facing his, "I have a few questions first.. If that's okay, sir." She peered at him from under her lashes.

Snape rolled his eyes in feigned annoyance.

"Why am I not surprised? Fine, out with it girl. You may ask… However, I am free to decline to answer."

"Right. Of course." Hermione reached into her satchel and pulled out a small roll of parchment. Snape snorted softly.

"Firstly… Do you do this kind of thing often? Have you done it with a student before? Could we arrange regular meetings? Can we have sex?" She read down her short list, then lifted her eyes to meet his gaze, fingers nervously twisting in her lap.

Hermione thought she saw amusement in the potion master's eyes for a split second. Then he cleared his throat and steepled his fingers before his face, staring into the fire.

"No, I don't do 'this kind of thing' often, anymore… If you must know, I haven't had any kind of sexual partner in several years now. No, I don't make a habit of corrupting my students…. You happen to be the first," he smirked at her, "As for your last question, I'll require some information from you before I can answer... Are you a virgin, Miss Granger?"

"No, sir." She said quietly.

"Good. Are you seeing anyone?" Hermione's head snapped up at that.

"Of course not, Professor.. I wouldn't be here if I was!" Snape rolled his eyes at her and gestured for her to come closer. Hermione eyed him cautiously before setting her parchment down on the coffee table. Then she stood and walked forward until she was standing between his legs. He pulled her down onto his lap and she straddled his thighs.

Severus looked up into her face, and said, "Calm down Miss Granger… I wasn't accusing you of anything. I merely want to make it known that should you wish to see anyone in the future, you are to let me know, and our arrangement will come to an end. No hard feelings. I do not share."

Hermione was having a hard time keeping eye contact with him as he spoke. How was he always so bloody intense all the time? Snape slid his hands up the sides of her thighs and over her hips to hold onto her waist.

"A few more things before we can begin…" Hermione looked down at his chest, unable to keep looking into his unreadable black eyes. He grabbed her chin softly and tilted her face back up.

"Look at me when I'm speaking to you girl," He growled. Hermione whimpered and nodded as best as she could, with his hand still gripping her face. Gods, she was ready to start humping him already. Show some restraint, Hermione! Don't let him know how desperate you are.

Severus leered at her nastily. Her thoughts were leaking freely from her mind again. He reveled in the fact that he was making her cream herself just by talking to her. The power was intoxicating.

"I don't handle being told no well, Miss Granger. However, neither will I ask you to do something you truly don't want to do…. You'll need to trust me if this is going to work. Is that understood?" Hermione nodded quickly.

"Yes sir." She was starting to feel out of breath already.

"I am in charge of your pleasure now… and your pain…if there is something you need, just ask." He finally let go of her chin and slid his hand back down to her waist. She felt delightedly small in comparison to his hands, they nearly wrapped around her whole abdomen.

"Are you on a contraceptive potion?" He asked. Hermione nodded emphatically.

"I took one yesterday, sir, it'll last me six months" she smiled shyly at him, wanting to avert her eyes badly, but knowing better. He smirked.

"From the hospital wing?"

She nodded again.

"Good."

He had brewed the supply himself and knew it was trustworthy.

"Eager as always, aren't we Miss Granger?... Tell me what you want from me, girl."

He brought a hand up to her chest and began to tease her nipple through her shirt. Hermione sighed and wiggled her hips against him gently.

"I… I want your cock, sir, please" Her cheeks were starting to burn up again. Why did he insist on making her feel so awkward?

He leaned forward to speak in her ear, allowing her to escape his eye contact, for the time being.

"Hmmm…. I think you can do better than that, little girl."

"My p-pussy is so wet for you sir,"

Hermione started to grind against him in earnest, and felt him hardening underneath her. "I need you to fuck me… please."

She was breathless now, with arousal and shame. They twisted together inside her in perfect agony.

Severus chuckled softly in her ear, "Much better. Okay, up you go," he said with a small smack to her bottom. "Go through that door on the left into my bedroom. Remove your clothes, keep the socks… Lie on the bed on your stomach, bum facing the door. Wait for me there while I figure out what to do with you"

Hermione climbed off of his lap and headed towards his room. Snape stayed in his chair, staring into the fire.

She entered his bedroom and paused to look around for a moment. His large four poster bed was the same walnut as his desk and coffee table, and it was draped in dark greens and browns.

The far side of the room was lined with windows that looked into the Black Lake. He had a wardrobe, and a small dresser with a mirror above it. Two small end tables placed on either side of the bed. But not much else. There didn't seem to be any personal effects or framed photos on the walls. The man remained an enigma, as always.

Hermione hurried to strip down to her socks and then placed her folded clothes and her wand on the side table. She climbed up on his bed, presenting her bum to the door. Oh gods, I'm in a Professor's bedroom… I'm in Snape's bedroom! That thought alone made her squirmy. She rubbed her damp thighs together impatiently. It felt like she had been lying there for ages… What is he doing out there??

Severus sat in silence for several minutes, staring into the fireplace. He wanted to give her ample time alone to get inside her own head and get herself nice and worked up. He knew he needed to make this night memorable if he wanted her to stick around for a while. Either way, he was sure it would be short lived. She would do her experimenting, and then she'd find someone younger, kinder, and better looking to fulfill her needs. So, he needed to make what time he did have count. Who knew if he'd have another opportunity like this in his life? Probably not.

With his plans for the night firmly planted in his mind, Severus stalked over to his bedroom, slamming the door into the wall with a bang as he entered. Hermione startled on the bed, but kept her face pressed into the quilt.

Fuck, she looked fantastic like that. Her bum was back to its normal hue- clearly he hadn't left enough of an impression the other night.

"Miss Granger!" He demanded, making her startle again in confusion. "What do you think you're doing girl, nude in your Professor's private quarters… Do you know how many school rules you're breaking right now?" He stepped up behind her, close enough that she could feel his presence, but not close enough for him to touch her.

"What? Sir I…. What?" She mumbled out, confused.

"Don't play coy with me Miss Granger. You know what you're doing…" he purred, "Do you have any idea what kind of danger you have put yourself in, girl?... You must know that parading yourself around like that makes it extremely difficult for a man to… resist."

"Mmmmm" Hermione moaned into the mattress. She was dying for him to touch her. She could feel that he was right there, so close. Having caught on to his game, she was more than willing to play along. She turned her head to the side to reply,

"Maybe I don't want you to resist…. Sir." Snape suddenly lunged forward and grabbed the back of her neck, and growled into her ear,

"You know not what you ask of me, witch. Do you know what I do to naughty girls who break the rules?" He was pressing her face firmly into the quilt. Hermione's voice was muffled when she answered,

"No, sir… Please, sir" She circled her hips, desperately trying to rub against him.

"Foolish girl… Fine, but remember that you begged me for it." He grinned and let go of her neck, straightening up behind her.

"Arse in the air. Spread your legs apart. Perfect… Now, keep still. And I want you to count. We'll see if you still want Teacher's cock after this…"

Hermione got into position and whimpered into her arms. Oh Gods, what is he going to do?? She was suddenly terrified. She struggled to take several deep breaths through her nose, trying to calm down. He told you to trust him, remember Hermione? You asked for this. She knew his current anger was mostly an act, but it still frightened her. And exhilarated her all the same.

Hermione heard a clinking sound behind her, and then a swoosh of fabric, and she suddenly realized he was taking off his belt. Oh fuck oh fuck. The imagery of Professor Snape taking off his belt was beyond sexy. But she had a pretty good idea of what he planned to do with it, and that was decidedly horrifying.

Severus knew the second she figured out his intentions by her quickened panting and the squirming of her thighs. Gods, she looked delicious. He adjusted himself in his trousers and then folded the belt in half, readying himself.

"Are you ready Miss Granger?" He inquired, reaching one hand out to fondle her bum. She sighed and pushed back into his hand, slightly calmed by his caressing.

No, She thought to herself, but whispered "Yes, sir" to him. He removed his hand from her and took a small step back.

"Brace yourself." he warned, and brought the belt down with a loud crack on her left cheek.

Ow ow ow! Hermione gasped and tried to catch her breath. She had to force herself not to move or reach back and grab herself. It stung like a thousand bees. The slap of the belt was concentrated on a much smaller area than his hand had been. A few seconds later she remembered to count and gasped out a weak,

"One!"

"Good girl. Again." Snape immediately brought the belt down on her other cheek, making a matching welt on that side. Hermione gasped again. Her eyes watered. Fuck, that hurts.

But the sting quickly faded into an intense heat that went straight to her center. She could feel her pussy getting wetter. Her body was betraying her. She felt absolutely barmy.

"Just a few more Miss Granger. You're doing so well" He soothed, and she lapped up the praise. Yeah, definitely barmy. She was letting him beat her and then soaking up his approval. That could NOT be normal.

He gave her six more smacks in quick succession and she burst into tears, counting each one. Yes, there it is. He had been waiting for her to give in. Snape dropped the belt onto the bed and caressed her bum with both hands, rubbing softly over the marks.

"Let it all out. That's right." She had done remarkably well for her first time.

And her arse looked beautiful, four large red welts on each side. She was a work of art. Her shoulders shook silently into the mattress, face hidden by her mass of chestnut curls.

Severus sat down on the bed next to her, and gently pulled her up.

"Come on up here little girl," he pulled her up onto his lap and she threw her arms around his neck, still crying softly. He rubbed both his hands up and down her body from bum to shoulders, over and over.

Hermione felt slightly ridiculous- completely nude and crying into her fully clothed Professor's neck. But his hand's gentle path up and down her body was so soothing, and she felt a quiet calm settle over her. Her tears came to a stop and she sniffled quietly into him. The skin of his neck smelled amazing, and as he muttered to her softly, she could feel the rumble of his voice against her chest. She almost felt high, like she could fall asleep in a matter of minutes.

"You should see yourself right now," Snape rumbled gently against her hair, "you look exquisite." Hermione picked her head up and tried to look over her shoulder at herself. Severus flicked his hand and a full length mirror appeared at the end of the bed.

Gods. Hermione breathed in a small gasp. She had never seen herself like that before. The image in the mirror was positively erotic. Her nude form straddled her Professor, legs spread wide. Her arse was decorated in bright red marks. She had always felt that she was a rather plain looking girl, but right now, with him, she found herself stunning. She smiled shyly into the mirror, and her Professor's eyes burned into her with an intensity that brought her arousal right back up to ten.

Hermione rolled her hips against him and felt his hard length press against her center. Snape grunted softly and ground right back against her,

"Go on girl, tell me what you need," He growled and palmed her cheeks, spreading them apart as he rutted against her. Hermione hissed at the burn of his rough handling of her battered skin.

"Please sir.. I need your cock in my pussy" she whined into his ear, and nuzzled her nose in his neck.

"Hmmm" he hummed as if trying to make up his mind. "I don't think so. Not yet." Then he flipped her onto her back on the bed, and hovered over her face.

"But.." She protested beneath him. Snape grabbed her chin and pressed his nose into hers and spoke quietly but firmly,

"Who makes the rules here?"

"You do, sir" She panted into his mouth.

"And who is in control of your pleasure and pain?"

"You are!"

"That's right. You'll do well to remember that little girl.."

His voice was honey in her core. He let go of her chin and slowly slid down her body, stopping with his face just above her pussy. He spread her legs wide and breathed in deeply. Fuck, she smells divine.

"My my Miss Granger… Tell me, did you enjoy the belt?" He nuzzled his nose into the creases between her thighs and her labia, careful to avoid the most sensitive parts of her.

"Not really… Sir… It was painful.." she stuttered out, hardly able to concentrate with his teasing. She writhed around trying to find some friction but his hands kept her hips firmly against the mattress.

"Really… Your pussy tells a different story… You know, it's hardly a punishment if you enjoy it," he smirked up at her, and then without warning plunged his tongue straight into her core. He wiggled his tongue as deep as it could reach and nuzzled her clit with his nose.

Hermione's eyes rolled back in her head. "Oh gods…. Please sir.. fuck.." She clenched the bedclothes in her fists. No one had ever put their mouth on her like that, and it was fucking fantastic.

Snape pulled his tongue from her briefly and hissed "yeeeesss" he kept up the back and forth pace of his nose on her clit while he spoke,

"You love this don't you?... Hermione Granger, brightest witch of her age… Spread out in her Professor's bed.. with his tongue buried in her snatch…"

He scooped his hands under her bum and held her in place, plundering her depths with his tongue.

Hermione almost screamed. The combined burn of his hands squeezing her bum, and his soft wet tongue all over her pussy was almost too much. She was going to lose it. Her hips snapped up to meet his face with every thrust of his tongue.

The building pressure in her core was winding so tight it almost hurt, and when he latched his lips around her clit and sucked she finally fell over the edge. She grabbed his hair in her fists and pulled his head against her, riding his face hard with a sob of completion.

Severus kept up his suction on her little nub and held on for dear life. Her thighs squeezed his head so tight he could just barely hear her muffled cries. His cock strained hard against his zipper. He could've come in his pants right then and there if he had let himself. It had been a long time since he'd been suffocated by pussy. And gods if he didn't want to let her just squeeze the life out of him in that instant. It would be one hell of a way to go.

She rode out the shockwaves of pleasure until her hips stopped twitching, and then let go of Snape's head. Her thighs relaxed back down to the bed and Severus laid his face on her leg and panted for breath.

Hermione's face turned crimson. "Oh Gods Professor…" She gasped, still out of breath, "I'm so sorry! I got a bit carried away…"

Severus snorted and scooted up the bed to lie next to her, squeezing his cock through his trousers.

"Don't ever apologize for that, witch…You were magnificent."

His lips were swollen and pink, cheeks and nose shiny with her juices. Hermione smiled shyly, still blushing, and laid down in the crook of his arm, head on his chest. Her hand trailed slowly down his stomach, questioning.

"Sir?..."

Severus sighed, "spit it out, girl."

Hermione grinned and stopped her hand just above his placket. "May I touch your cock, sir?" She said sweetly.

"Thought you'd never ask," he smirked, unzipped his trousers and freed his member. Hermione gave him a squeeze and he grunted at her. "Make me come, little girl. I'm too close to fuck you right now."

"Mmmm yes sir."

She replied and began to stroke him slowly. Hermione slid down the bed, closer and closer till she was face to face with his weeping tip. She poked her tongue out to lap up the bead of precum. It was a bit salty, but not too bad. Snape grunted and thrust his hips towards her mouth.

She could take a hint. She tentatively wrapped her lips around the tip of his cock and sucked. That earned her another quiet groan. She took more of him into her mouth, getting down about one third of the way before her gag reflex triggered. How on earth do people deep throat? It must take a lot of practice... She thought, and then got to work, taking as much of him into her mouth as she could and then coming back up, over and over. Snape's hips were snapping up gently to meet her, but she could tell he was holding back.

She kept up her rhythm and grabbed at his sack, gently pulling down on his bollocks. "Fuck!" He grabbed her by her hair and pulled her off of his cock with a pop.

"Lie down on your side of the edge of the bed," he instructed through gritted teeth, holding himself at the base of his shaft. Hermione got into position and Snape got off the bed and stood up next to her, his cock level with her face.

"Open up," he leered, and lightly smacked her lips with his tip. Hermione opened up, and he pressed into her mouth slowly, one hand holding the back of her head.

Snape slowly pushed his cock deeper into her mouth, and when he got about halfway in her gag reflex triggered and she tried to pull away. He held her in place, but kept his cock still and didn't push farther.

"Relax…. Yessss.. You can take it." He crooned and slowly pulled in and out of her mouth, only pushing in halfway each time. Hermione did find this position was slightly easier on her jaw, and she could take him a bit deeper than before. The fact that she was held there helplessly while he fucked her face was exhilarating. His cock was hot and heavy on her tongue, and when he pushed even deeper, the sensation of her throat being filled shot straight to her core.

"Look at you… You love having your mouth stuffed full of cock, don't you?" His deep baritone was hindered slightly by his stuttered breathing, but was effective nonetheless. Hermione did her best to nod while he held her head still,

"Mmph hmmph."

She hummed around his cock, and the vibrations sent a shiver down his spine. He pumped faster into her mouth, trying to hold back from going too deep. She looked like a goddamn angel with her sweet lips stretched around him. She stared into his eyes as he used her mouth, perfectly willing to let him have his way with her.

Severus pushed just a little deeper, and a single tear rolled down her cheek from the strain. Fuck, he was going to lose it.

"Open your mouth wide girl, stick your tongue out." He panted as he pulled his cock free. She complied and he stroked his cock fast and furious, aiming for her soft pink tongue.

It was almost violent the way he handled himself, Hermione thought. His lip was twisted up in a sneer as he pumped his cock in her face. She held her mouth open in anticipation, eager to taste him. Yes, come in my mouth Professor, fuck. She tried to communicate this to him with just her eyes, and he must have gotten the message. His orgasm shot out of him in thick white ropes, some landing in her mouth, most on her cheeks and chin. His jaw turned slack as he milked out the last few drops onto her tongue.

He tasted bitter and salty, with a small undertone of sweetness. She swallowed what was on her tongue, and then scooped up what was left on her face and licked it off her fingers with a smile. Snape huffed at her in amusement,

"Good girl. You just can't get enough can you?"

Severus stepped out of his trousers and pulled his shirt off too, letting it drop to the floor. It was the first time she had seen him completely naked. His chest was trim but wiry, with a soft smattering of dark hair that made a trail all the way down to his cock. Even in the faint candlelight she could see he was littered with scars- some small and white, others thick and pink. She wanted to trace each one with her tongue.

Snape removed his socks and climbed into the bed behind Hermione, pulling her back against his chest.

"Did you tell your friends you're in detention tonight?" He asked, absently running his fingers through the triangle of hair on her mons.

"Yes," she replied, "but I said I'd go straight to Grimmauld Place from here. So they won't miss me tonight."

The eighth year students had been awarded some special privileges that year. They were allowed to leave the premises on weekends, as long as their scores didn't suffer and they weren't late to classes on Monday morning. Hermione had been visiting Harry and Ron at Grimmauld Place most weekends. It was strange not to be with them everyday at Hogwarts, and at least Grimmauld had a good library she could use for homework if need be.

"I see. I suppose we have some more time then. If you'd like to stay longer, that is."

Hermione smiled and rubbed her arse against him, "Yes please sir."

He grabbed her hip to still her movement and grumbled at her,

"Give me a minute witch. Some of us aren't teenagers anymore." She giggled quietly.

"Sorry"

"Just rest for a minute, we've got time." He closed his eyes. Within moments she started her wiggling again. Severus leaned back and pinched the bridge of his nose.

"Good gods girl, are you always like this?" He demanded.

No, she thought, you just drive me batty.

"No, sir" Hermione replied.

"Just for me, then?" Severus huffed and pinched her nipple.

"Yes sir" She smiled.

"Fine," he sighed, feigning annoyance, "Since I clearly won't get any rest until you've gone, sit up" Severus sat up in the bed and leaned back against the headboard, gesturing for her to lie in front of him.

"Touch yourself for me. I want you to be nice and slippery when I get my cock in you." Hermione laid on her back between his legs, head facing the foot of the bed. Severus propped his arms up behind his head and settled in to watch.

"Pretend I'm not here…. Show me how you touch yourself alone in your bed at night.."

Hermione blushed, hoping he hadn't seen some of the things she had been imagining at night. She started to touch her nipples softly, rolling them between her fingertips. Snape chuckled.

"Oh, I've seen them."

Hermione groaned and covered her face with her hands. Severus snapped up to his knees and grabbed her hands, pinning them on either side of her head. Leaning over her, he spoke in a quiet but hard tone.

"What have I told you about hiding your face from me?"

She flinched but didn't look away from him.

"As long as you are seeing me I will be responsible for you. No part of you, body or mind, is off limits to me. Do you understand?"

Hermione nodded emphatically.

"Now can I trust you to control yourself, or do I need to tie your hands to this bed?"

She shivered underneath him, hesitant to answer. Severus grinned at her.

"Oh? You do want to be tied up, don't you? I think that can be arranged…"

Severus leaned back and grabbed his wand from the side table.

"Lie in the center of the bed." Snape commanded.

Hermione crawled up the bed and laid flat on her back. He flicked his wand at her and her arms shot out to her sides and soft leather cuffs encircled her wrists, attached to the bed posts. There was enough slack that she could move her arms a bit, but she couldn't reach her own face or Severus. She squirmed and pulled against her bonds, testing them.

Snape kneeled over her and watched with dark glittering eyes. "I was planning on letting you come…. It's a pity only girls who follow the rules get to do that.." He brought his pointer finger down to her quim and ran it up and down her folds.

"I want you to tell me when you're about to orgasm, and I'll stop. Do not come little girl, or you'll regret it." He warned, and started to circle her clit.

At first it was nice, she settled back and enjoyed the stimulation. But he kept up the perfect pace of tight little circles, slowly lightening the pressure as he went. The fire inside her was starting to burn bright and hot, but she was still holding on. Until he started muttering to her.

"I've seen some of your little fantasies Miss Granger… you've got quite the dirty little mind, don't you?... Tell me, which one would you like to try first?...

The one where I come all over your uniform skirt and then send you to class with the stains?" Hermione shook her head frantically, hips gyrating and twitching.

"No, sir, please don't." Severus smirked and picked up the pace on her clit.

"Oh but the idea arouses you so much. You want everyone to know you're my little come slut, don't you?"

"Uhhhhh Gods," Hermione moaned. Her face was bright red and her hips were dancing at a frenzied pace.

"Don't you dare come, Hermione," he commanded, and it almost pushed her over the edge.

"Stop! Please sir, stop, I'm going to come." She begged, scrunching her face up in a grimace. Severus removed his finger from her and stuck it in her mouth. She sucked it clean.

"Good girl. This is the kind of behavior I want to see… Keep it up and maybe I'll let you come again tonight. You want to be my good girl, don't you?"

Hermione nodded eagerly, still sucking on his finger.

"Good. Again. Same rules, tell me when to stop." He pulled his finger free from her mouth and started on her clit again.

Gods, not yet! I need more time.

This time he took up his murmuring again right away,

"If not the come stain fantasy… Perhaps you'd like to be lent out to all of my friends?... Oh yes, I know you've pictured it.. I'll invite them for dinner and you can crawl around under the table, servicing us all in turn.." It was a fantasy he knew she didn't actually want to try- not to mention something he'd never be up for- but it was fun to tease her about.

Hermione shook her head emphatically, "No sir, I don't want that!" She was already getting so close, her hips were moving of their own accord. She was climbing towards her peak much faster this time.

"Oh, I think you do, Miss Granger… You'd do anything to please me…wouldn't you? Dirty girl. You'd suck a dozen cocks if I asked you to... Just to earn my approval.."

"Mmmmm oh my God, I can't, I can't!" she babbled, pulling at her restraints. She was shaking her head back and forth like a woman possessed. Her pussy made a slick clicking sound with every circle of his finger.

"Please!" She shouted, "Stop, sir, please!" Snape pulled his finger away, and brushed the damp hair back from her forehead.

"You're doing so well, Miss Granger." He soothed, and pushed her right knee up so he could grind his now hard cock against her thigh.

"You feel that princess?... You look utterly debauched and it's driving me mad…" Fuck. He had wanted to drive her to the edge a few more times, but he just couldn't wait anymore. Severus rubbed his glands against her folds, slicking his tip in her juices. They groaned in unison. Hermione was panting like she'd run a marathon, her eyes were wild with need.

"Fuck. I can't wait anymore.. I need to get inside this tight little cunt." He growled, rubbing his cock up and down her folds. "Tell me what you need girl, and I'll give it to you" He was holding her chin again, she could feel his hot breath on her face.

"Kiss me! Please sir," she moaned, bucking her hips up against his.

Severus paused. He hadn't been expecting her to say that. He'd be lying to himself if he said he didn't want to kiss her. No, he'd purely been following his old rule. No kissing helped keep people at arms length, where they belonged.

But, new life, new rules, right? Besides, now that he'd thought about doing it he wasn't sure he could stop himself even if he wanted to.

After a short hesitation he leaned down and practically devoured her mouth, while simultaneously sliding his cock as deep into her as it could go, in one smooth thrust. Hermione screamed into his mouth, and kissed him back in a frenzy, wrists pulling hard at her restraints.

Fuck. Her pussy felt like it was about 200 degrees, and squeezed around him like a vice. Even after having had one orgasm shortly before, he wasn't going to last long. She felt too good.

Hermione was seeing stars. Gods he was definitely bigger than Ron. And though she wasn't in pain, she was certainly being stretched to her limits. She was pretty sure he wasn't even fully inside of her yet. He could undoubtedly hurt her if he wanted to. She had never felt more full in her life.

And the way he was kissing her, fuck, she felt like he was going to eat her whole. He caressed her tongue with his the same way he ate her pussy, and it sent tingles all the way down to her toes.

Snape started fucking her in earnest, and kept his mouth latched to hers. Neither one had come up for air, though Hermione was keening and moaning into his mouth. She wrapped her legs around his waist and pulled him in even deeper.

Severus kept thrusting and thrusting, changing up the angle and experimenting with different speeds. He got so lost in the sensation of her clenching walls and sweet mouth he barely noticed her distress until she started to hum frantically and tried to move her head to the side, away from him. He pulled his mouth off of her abruptly, gasping for air, and slowed his hips down to a crawl.

"What is it Princess? Am I hurting you?" He realized with a start that he may have been going a little too hard on her for their first time together. Get a hold of yourself man, she's counting on you to take care of her.

"No!" She said, a bit too loudly. She blushed, "you aren't hurting me, sir. Please, sir, may I come? I'm so close."

He had forgotten he'd told her not to come. You dunderhead. He breathed out a sigh of relief and kissed the tip of her nose.

"Yes, you may come Hermione" He began to fuck her again in earnest, this time leaning back so he could fit a hand between them and flick his thumb over her hard little nub. Hermione keened and her eyes rolled back in her head.

"Ooooohh yesss. Please fuck me harder, Professor." She moaned, snapping her hips up to meet his thrusts. Severus picked up the pace, and flicked his thumb expertly over her clit. She was so drenched he was gliding in and out of her with ease, every thrust created a lewd smacking sound.

"Fuck, yes, your little pussy is so wet and tight. You feel amazing around my cock." Snape growled down at her, clenching his teeth. He just needed to make her come and then he could let go. Gods, her pussy had him in a choke hold.

Hermione held on for dear life as he fucked her into the mattress. He looked like some kind of dark avenging angel above her, nostrils flared and sweat on his brow. The pressure in her core was wound up so tight it was painful. She was so close to release. She just needed one last little nudge.

"Take my cock, little girl. Take it all. Come for me Hermione. Now."

"Uuhhhhhh Professor!" She shouted, hitting her peak.

"Say my name," Snape growled, snapping his hips into her relentlessly. Hermione's eyes popped open at this, and she threw her head back and called out,

"Severuuuuus! Yesss!" Everything that had built up during her edging was released at last. Her pussy spasmed and twitched hard around his cock, pushing him over the edge alongside her. He grunted into her neck as he filled her with his seed.

Snape's hips came to a stuttering stop and he waved one lazy hand, releasing Hermione's wrists from their cuffs. She immediately wrapped her arms around him and he rolled the two of them over onto their sides, tucking her in against him.

They laid there panting for a few moments till their heartbeats calmed to a normal rhythm, and their sweat cooled on their skin. Hermione wanted to stay there in his bed all night, but she knew she'd have to leave soon. Harry and Ron were expecting her. She huffed a small laugh when she pictured the looks they'd have on their faces if they saw her right now.

"What could possibly be amusing to you right now?" Severus grouched into her hair.

"Oh just thinking about what Harry and Ron would say if they knew what I had been up to tonight,"

"You aren't planning on telling them, I hope. I don't need tweedle dee and tweedle dum busting down my door.." he drawled tiredly.

"Gods no, I'm not going to tell them!... Not yet anyways…" She trailed off. He wasn't sure what she meant by that, but he was too exhausted to ask.

"It is getting late though, princess. Best you run off now before your friends start to wonder," Severus turned them slightly so he could lean over her face,

"Go on and get dressed," he gave a small smack to her bum and rolled over onto his back, closing his eyes.

Hermione sighed and crawled out of the bed, wincing at the stiffness in her limbs and the bruised feeling of her bum.

"Can I use your loo, sir?" Hermione asked. Snape blindly gestured with one hand,

"Door to the left"

Before she could go Severus suddenly reached out and grabbed her wrist, glancing at her through one squinted eye.

"Don't clean up. I want my come leaking out of you all night. You can wash tomorrow."

"Yes sir"

Snape let go of her wrist and she headed for the bathroom and closed the door gently. Hermione emptied her bladder and then carefully patted herself dry, trying not to wipe up their combined fluids. When she finished she stood up and peered at herself in the mirror.

She was a complete mess. Her hair was no longer a mass of curls but rather a jumble of frizz from rubbing against the bed. She looked tired and flushed, and she was bloody starving, not to mention parched.

She wet her hands with the tap and tried to smooth her hair down into something resembling tidy. That was not going to do it. Hermione cracked the door open and peaked out at Snape. He was lying on his back with his arms behind his head, eyes closed. The sheet was pulled up to his waist. She couldn't tell if he was sleeping or not.

She quietly summoned her wand from the side table and clicked the bathroom door shut once again. She conjured a scrunchy with her wand and got to work pulling her hair into a messy bun on top of her head. What she really needed was a proper shampoo and conditioner, but this would have to do for now. Hair taming spells had never worked well for her.

Hermione grabbed the tall drinking glass on the vanity and filled it up with a quick aguamenti and drained nearly the whole thing in quick gulps. She sighed and wiped her mouth before filling it up again and carrying it out to the bedroom. She gently set the glass down on the side table next to Snape and began to dress quietly.

"No knickers," Snape rumbled quietly, eyes still closed. Hermione startled slightly, she'd thought he was asleep. She huffed softly, ready to argue, when he interrupted her,

"You better not be about to tell me no, girl," he warned, his eyes open now and narrowed at her in challenge.

She did not want to show up at Grimmauld Place with semen dripping down her thighs. But she also didn't want to risk Snape's wrath.. He might not bother to invite her back. Fine, she thought, let's just hope the boys have already gone to bed by the time I arrive.

"Yes, sir" she conceded petulantly, arms crossed over her bare chest.

In one fluid motion Severus had whipped back the sheets, stood up and grabbed her arm, pinned it behind her back and pushed her onto the bed on her stomach. He held her down forcefully and barked in her ear,

"Watch your attitude young lady. Clearly you have gotten too comfortable and have forgotten who you're dealing with. I will not hesitate to beat your bum black and blue, and this time you will not enjoy it. The belt I gave you tonight was just fun and games. You'd do well to avoid a real punishment from me. Do I make myself clear?"

He took care to announce each syllable clearly and dangerously. Hermione trembled beneath him.

She wanted to cry. She had never handled disappointing the authority figures in her life very well. Even in muggle primary school the smallest comment from a teacher to 'pay attention' or 'quiet down' would make her tear up.

"I'm sorry, sir," Hermione whispered, chin wobbling with barely suppressed tears. Severus took a deep calming breath and eased up his pressure on her, but kept her pinned to the bed.

"You want to please me, don't you?" His voice was calmer and quieter now, and it pooled deep down in her core. "I know you do… I know you want to be my good girl." Snape nuzzled her cheek with his nose and she sighed.

Merlin, the man was impossible. His mind games had her on an emotional roller coaster. She couldn't keep up.

"Yes sir, I want to be your good girl," Hermione breathed.

Severus wondered if he had been too harsh with her. But he had warned her in advance that he didn't take kindly to being denied. She knew what kind of man he was, she knew he had a short temper.

Snape knew that deep down she loved the idea of walking around in public with the evidence of their coupling all over her. She enjoyed the humiliation. And a part of her wanted to show the world she was a desired sexual being. But she wasn't able to admit that to herself yet. That was something he'd have to train out of her.

Severus loosened his hold on her arm and stood up, pulling her to her feet and wrapping her up against his chest in an embrace.

"Don't lie to yourself Miss Granger," he rumbled into the top of her head, "You know you love the idea of facing your friends with my essence dripping down your thighs… You want the world to know you're a naughty girl… You're not the prissy little prude they think you are… There's a lot more than books and research inside that brain of yours…" Severus leaned back slightly and grabbed her chin, tilting her face up to look in her eyes.

"If only they could see you the way I have… They should be so lucky. I've never witnessed anything as captivating as your face in the throes of orgasm." Hermione flushed a deep shade of pink, and struggled not to break eye contact.

Gods, who was this man? It was almost absurd how much he sounded like a character straight out of a romance novel. But she wasn't about to pretend it didn't absolutely flood her knickers. Or at least it would, had she been wearing some.

Snape leaned down and kissed her deeply, hands sliding back to cradle the back of her head. Hermione wrapped her arms tighter around his waist and kissed him back breathlessly. His lips moved against hers with practiced ease, tongue slipping in and caressing hers with a gentleness that turned her knees to mush.

He pulled back after several moments and spoke against her lips,

"You really do need to get going now Miss Granger."

Severus reluctantly pulled away from her and flicked his hand, summoning a dark silk dressing gown. He slid it over his shoulders and led her over to her pile of clothes, motioning for her to finish dressing.

As Hermione pulled on the rest of her uniform- sans knickers- she questioned him,

"When can I come back, sir?"

Snape waved a hand at her, "I'll let you know this week." When she finished dressing he followed her out to his sitting room. She grabbed her satchel from the floor and gave him a small smile.

"Goodnight Professor."

"Goodnight Miss Granger… Oh, one more thing," he drawled with a small smirk on his face. "You might want to consider keeping your legs closed, lest your friends smell you and figure out what you've been up to…" He looked decidedly pleased with himself.

Hermione squeezed her already damp thighs together in embarrassment. Then with one last smile she exited his sitting room.

After she'd gone Severus noticed she had left her small scroll of parchment on the coffee table. He unraveled it with a small chuckle. It was titled 'Questions for Professor Snape' in her neat round script. Near the bottom of the scroll was another list; 'Pros and Cons' The pros column was quite full, and the cons only had one item, 'Forbidden/secret relationship' which was then crossed out with an arrow pointing it instead to the 'pros' list.

Severus rolled up the parchment with a small huff of laughter and took it to his bedroom, tucking it neatly inside his dresser. Only Hermione Granger would write a pros and cons list for sleeping with her Professor.

He would have to make sure to impart the importance of not writing their secrets on paper for anyone to find. It was only then Severus noticed the small pink knickers sitting on his pillow. He grabbed them and put them to his face, inhaling her sweet musky scent.

He slept that night with her knickers clenched in his fist.

A/N: I hope you caught me making fun of myself in this chapter, and kinda sorta breaking the 4th wall a bit :)
