How many days had she spent trying to perfect this outfit? First came the shopping in Diagon Alley, but the bows and skirts they had there weren’t quite what she was after. Despite the winter chill, she wanted something that was short enough to tease Professor Potter to his last wit.

It’d become the favourite game of Narcissa Black. Her dear, darling, favourite professor always tried to maintain his impartiality within class, but whenever she shot him those seductive looks that she spent hours practising in the mirror, he practically became putty in her hands. From that moment forward, his every focus was upon her. No matter how she moved, whether it was the most casual yawn or a little squirm to hike up her skirt just that extra little bit, Professor Potter’s eyes were upon her every second.

Standing in front of a mirror just within view of the windows of Magnifique, Narcissa knew that she’d struck gold with her outfit. The French witches and wizards on the street kept glancing her way as they passed, as though she were some perfect mannequin displaying the most chic outfit of the year upon her flawless body.

“It’s beautiful,” Narcissa murmured to herself.

Hogwarts’ dress code wouldn’t let her get away with this during classes, but the weekends would offer the perfect excuse to wear these clothes. The professors rarely enforced the dress code on the weekends or after classes were done for the day. Even if this skirt was dangerously short, she doubted that she’d receive more than the slightest rebuke over it.

The seamstress swept with a perfect smile upon her lips. Narcissa could tell that this wasn’t just a smile of convenience—the type that was offered to anyone buying her wares—this was something genuine that reflected the model who made the outfit truly shine.

“I’ll take it,” Narcissa told the middle-aged witch.

“Would you like it packaged up?” The woman asked, gesturing to the rows of paper that could enrobe the clothes and form the perfect package within a gift bag.

“No,” Narcissa shook her head with a bright smile. “I’ll wear it out.”

After a brief transaction, Narcissa strutted out of the shop with a confidence that she rarely felt. While she wasn’t one to be shy, she knew that she looked obscenely gorgeous in this outfit. If Harry were here…

No, she had to temper such thoughts. If she got too carried away, she’d have to come up with an excuse to retreat back to her family’s vacation home so that she could find a moment of privacy to sate that desperate heat between her thighs.

Shaking her head, Narcissa jostled out of the desperate thoughts as best she could.

In just a couple of weeks, she’d be back at Hogwarts, and then she could put her plan into action.

PAGE BREAK

The first day back from the holidays came easy to Narcissa. Many men in her year noticed her fancy dress, but only the bold dared to comment upon it. She disarmed each potential suitor with a chaste smile and a soft reply. Few chose to continue the conversation, and those that did quickly understood that she was not interested in them. Those that didn’t get the hint received more than a simple stinging hex.

By the next day, everyone was fully aware that Narcissa Black was not to be their object-of-interest for the term. They could find anyone else—Narcissa didn’t care in the slightest—all that mattered was that Professor Potter lusted over her.

She saw him during meals within the Great Hall. He sat up high with the other professors, but she knew that he only offered them a tertiary focus. His eyes kept scanning the hall until he finally spotted her perfect blond hair. From that moment forward, Narcissa couldn’t spend more than five seconds without feeling Professor Potter’s eyes upon her.

When it came time to leave, Narcissa left with her classmates without a single glance back to Professor Potter. Even though she was eighteen and ripe for marriage, such things were rarely discussed until after a witch had graduated from Hogwarts. None of her classmates suspected in the slightest that she had some type of affair going on with Professor Potter. The aloofness she presented aided in that.

Their first class together went by plainly. Narcissa did her utmost to ignore Professor Potter at every turn. He used to be so perplexing to her; she hadn’t been able to understand why he didn’t ogle her body like so many others did, and he also didn’t pick up on her subtle hints that it was him and his wonderful body that distracted her from performing at her best. It wasn’t until he made a move on him that he finally seemed to truly understand just how turned on she got around him.

Now, it was his turn to make the move.

Anytime he crossed by her desk, Narcissa deliberately ignored him.

Whenever she stared up at him when he was sitting at his desk and he finally chose to return her gaze, she twisted away quickly.

She could see how it was annoying him. By the end of their class together, he seemed overwhelmingly frustrated. No one had done anything to embarrass themselves today, so Narcissa could only conclude that this victory belonged to her.

Returning to her common room, Narcissa treated herself with a sly smile.

In time, Professor Potter would be hers forever.

Although they’d already coupled together, that wasn’t enough for Narcissa. Her nervousness in his classroom had faded thanks to their many nights together, but she hoped for greater results. She wasn’t destined to be a mere housewife. One day, Narcissa knew that she’d achieve something greater than that.

But before then, she still needed to sort out the need for a husband. Her family wouldn’t tolerate her remaining unattached even if she delved in deeper, more complicated magical topics.

If she was being honest with herself though, those career aspirations paled in comparison to the life-long goals she dreamt of in becoming Professor Potter’s wife.

But she didn’t intend on compromising upon either goal. She would reach both, and that would be her crowning achievement.

She only needed Professor Potter to agree to as much.

In the moments between classes, Narcissa ensured that she was seen by Professor Potter without lingering within his gaze for too long. She teased him by playing with the hem of her skirt and letting the top buttons of her top become undone. The familiar signals that he sent towards her went unanswered on her part; she wanted more from him than just the casual hook up.

If he pursued her as she wished, then she’d become his forever.

Days passed, and Narcissa did all she could to avoid Professor Potter. In the late nights she spent awake craving his touch, it became almost unbearably difficult. Her fingers ended up soaked with her juices as she eked out a fraction of the pleasure that she could find with Professor Potter, but she knew that it’d be worth it when he finally came after her.

Eventually, she became aware of his gaze in the corridors. Something within her could sense his heated looks that sent sparks down in between her thighs, but she never looked back at him. Every moment that she ignored him compounded upon the lust in his gaze, and that only added to the shivers that were sent down her spine.

During their second class together, Narcissa finally sensed a feeling of hurt within Professor Potter’s eyes. It was the only time that she finally gave in and stared back at him with the same longing that he stared at her with. At that moment, he understood, and then her little game dissolved completely.

Professor Potter was after her, regardless of what deceptions she sent his way.

Still, Narcissa ducked away from him in the corridors and tried her best to avoid his attention, but he always seemed to find her. The thrill of the chase excited Narcissa unlike anything else.

Once, she’d been the one in pursuit of Professor Potter and his unbelievable body. Now, she was the one being chased. The feeling made the hairs on her arms stand up straight and her entire body tremble with delight the second that she felt Professor Potter’s gaze rest upon her. His lust mirrored hers, and it was only a matter of time before he tracked her down.

That night came only two evenings later when Narcissa ended up in the restricted section of the library. She had a pass that allowed her to access some of the more questionable tomes that delved into the deep research of how dark wards interfered with good-natured charms.

The books often screamed at her as she pulled them from the stacks. It was as though they sensed her intentions on writing an essay that explored the counters to dark wards which led them to their utter terror. It was almost comical if not for the annoying screeches that kept ringing out.

Had she not shuttered a couple of tomes at that moment, she wouldn’t have noticed Professor Potter creeping up behind her in the distant shelves on the far side of the clearing.

In every free moment that she had, Narcissa wore that seductive outfit she’d found in France those weeks ago.

The top had long sleeves but opened up around her collarbone. It didn’t go so far as to reveal much of her cleavage, but she knew that it would be enough to draw Professor Potter’s gaze. The same came with the skirt that clung to her thighs; he was a fiend for staring upon any bare bit of skin she had to reveal to him, and with how high her skirt climbed up her legs, she knew that he’d spend his days trying to recall a perfect image of what lay between there.

Sitting down, Narcissa let every inch of her creamy skin be displayed to Professor Potter as he crept up behind her. He didn’t seem aware that she knew exactly where he was, which suited Narcissa perfectly.

She didn’t startle when his hands landed upon her shoulders.

“You’ve been a naughty witch,” he whispered into her ear with the heat of a thousand suns.

Narcissa couldn’t help the shiver that ran down her spine. It was all too much to finally have him close to her.

“I’m sorry,” she apologised meekly. “I wanted your attention on me.”

“You already had it,” Harry replied as he leaned in even closer to her. Narcissa could smell his aftershave and feel the warmth emanating off of his cheek upon the back of her neck. “I saw you teasing me every day.”

“And?” Narcissa asked aloud. “Are you going to torture me over it?”

“In a sense,” Harry chuckled loudly. He pulled away from her, and Narcissa fought the urge to look back at him. “I’m going to make you wish that you hadn’t spent so long teasing me.”

His strong arms wrapped around her waist, and despite Narcissa’s struggles, he refused to let go. Her perfect fringe remained in place, as did her wavy blond hair that collected over her shoulders. Professor Potter clung to her like a man without a life vest. Her meagre efforts ended quickly as she relaxed into her lover’s arms.

“You’d better have a good plan for dealing with a naughty witch like me,” Narcissa teased him as she rubbed her arse against his crotch. She could feel his cock growing with his trousers as she rubbed back and forth, despite his efforts to stop her.

“I have millions of ideas of what I want to do to you, but none of them can overwhelm how badly I want to fuck you against the bookshelves right now,” Harry groaned in her ear. He bucked his hips against her, and the heat that was pooling in her core nearly exploded.

“As long as you don’t ruin my cute outfit, I don’t care what you do to me,” Narcissa told him.

“I should rip it off of your body for teasing me so much with it,” he said as he reached down and grabbed the hem of her skirt. He teased it all the way up until the pale skin of her arse was exposed. A silk green thong rode up in between her cheeks, just the way Harry liked.

“If you do that, I’d never forgive you,” Narcissa replied as she pushed her arse back against his crotch.

“Don’t be so sure about that,” Harry chuckled as he unzipped his trousers. The moment Narcissa felt his burning-hot cock prod against her arse, she wanted to grab onto it and stick it right up her pussy so that he could start fucking her already. “I seem to recall a few nights where you absolutely begged for my cock. You seemed to be willing to do anything for it. I think forgiveness might be included in that.”

“You do have a truly magnificent cock,” Narcissa moaned. “But my outfit is almost just as nice.”

Harry snorted and pulled her thong aside. The cool air brushed across her swollen pussy and made her shiver with anticipation. “I’ll let you keep it intact for now, but if you ever dare tease me again like you have been…”

“You’ll what?” Narcissa asked, desperate to hear whatever he had in mind.

He narrowed his eyes on her and brought one hand up around her throat. He didn’t squeeze her hard; the pressure merely added to the excitement of it all.

“I’ll rip it off piece by piece and then fuck you until you can’t walk anymore.”

Narcissa hummed happily at the thought. “That sounds like more of a reward than a punishment.”

“Maybe I’ll just tease you instead,” Harry said as his cock slid down and nestled itself in between Narcissa’s thighs. The shaft ran right along her labia, and her juices were already spilling out onto it. “I’ll leave you begging to cum but never letting you until I feel like you’ve learnt your lesson.”

“Sounds hot to me,” Narcissa laughed.

Harry shook his head at her. “You horny little witch. Fine then; I’ll just ignore you like you’ve been doing to me.”

“Will you be able to last though?” Narcissa asked him with a wicked grin. “I can be very persuasive.”

From the annoyed look on his face, Harry had quickly realised that there was no winning this argument. No matter what he tried to suggest, Narcissa was always going to find a way to counter it.

“You can be such a brat,” he told her.

“Comes from growing up as a pure-blood princess like me,” she teased him. “But you know what brats need?”

“Punishment,” Harry finished for her.

“No,” Narcissa shook her head. “A good, thick cock up their tight pussies to put them in their place. They need to be fucked over and over again until they run out of breath to be defiant in any way. You’ve got to—”

Her words cut off as she let out a guttural moan. Harry’s perfect cock still stretched her out better than her fingers or any toy ever could. He speared all the way into her depths, filling her with an intense warmth that made her toes curl. Nothing else could be as good as this, she knew.

Those painful weeks of missing Harry’s cock were utterly made up for at this moment. She was shameless as she pushed her arse back to meet his eager thrusts into her pussy. Her walls greedily tried to cling to his thick, pulsing shaft to keep him locked inside of her, but Harry wasn’t going to let her take control at all.

As Harry’s hips slammed against her plump arse, Narcissa staggered forward and ended up falling against a bookshelf. Harry followed her, keeping his cock in her sweet pussy, and slammed his weight against her to keep her on her own two feet. Her face was mashed up against a couple of books that shrieked at being disturbed, and that gave her the confidence to let out a loud moan, knowing that anyone who happened to overhear it would merely assume her voice to be coming from another book.

“Fuck, you’re splitting me open,” Narcissa cried out as she grabbed onto the bookcase to help take some pressure off of her buckling knees. She and Harry certainly weren’t strangers to rough sex, but there was something primal about tonight. It had to be how long it’d been since they’d last touched each other. Harry was pounding into her pussy like a man possessed, and she loved it too damn much to be able to stop herself from announcing it.

“You’re so naughty for a princess,” he groaned, throwing her own words back at her. He reached up and groped her breasts roughly, squeezing them through her dress. He kept pulling his hips back until just the tip of his perfect cock was left inside of her before he slammed all the way forward, making her arse sting in a mixture of pleasure and pain from the force of his thrusts. “I love your tight pussy so much. It feels incredible.”

A burst of pride shot through Narcissa. These were the words she wanted to hear from him. Everything he ever said about her made her feel like she was being worshipped. It made the heat in her core flare up with excitement.

“I love how sweet your voice sounds when you cum,” Harry continued. “I can’t wait to hear it.”

The pleasure is almost blinding. His cock felt like it was hammering her lungs, forcing her moans out of her with every thrust. The books on the shelf kept crying out in protest as her body was battered against them.

Narcissa’s walls began to squeeze and contract around Harry’s cock. She knew that she was so desperately close. All of this teasing that she’d been doing had gotten her quite worked up as well, and now that she was finally experiencing sex again, her orgasm was building up so quickly.

“That’s it,” Harry groans. “Milk my fucking cock.”

Narcissa’s pussy clamped down hard around Harry’s cock, pulsing in time with the rapid beating of her heart, as her orgasm crashed over her. The bookshelf trembled under the forcefulness of Harry’s final thrusts as he rammed his cock as deep inside of her pussy as it could go and then—

There was an incredible rumble as Harry roared aloud in pleasure. His hot seed began to shoot out inside of her just as the bookshelf collapsed backwards.

Narcissa was too caught up in the throes of her orgasm to realise what was happening until it was too late. She barely managed to get her hands up in time to catch herself as she fell forward with the bookshelf, but Harry’s weight on her back crushed her down onto the toppled bookshelf. He didn’t seem to care about what happened either as he kept bucking his hips against her ass, spewing out the last drops of cum into her womb.

It was only when the two of them finally came back to reality and began to catch their breaths that they realised what had just happened.

“Shit,” Harry cursed in frustration. “Madam Pince will be here soon. Even she must’ve heard this.”

“That is if no one else shows up first,” Narcissa pointed out.

And yet, neither of them moved right away. The post-orgasmic bliss of simply being connected was too much to throw away so easily. It wasn’t until the sound of rapid footfalls approaching their position that Harry finally climbed off of Narcissa and helped her to her feet.

Narcissa quickly pulled her thong back over herself and smoothed out her skirt back to its normal length. She could feel Harry’s seed dripping out of her pussy and staining the delicate fabric of her thong. Some of it even escaped and began to drip down her legs.

Harry collected the books she’d been looking at and stuffed them into her bag. He’d stowed his cock back in his trousers as well and tried to make himself look somewhat presentable, but it would be abundantly clear to anyone who saw them that they were a little dishevelled.

Just when they were about to leave, Madam Pince rounded the corner with a fury unlike anything that Narcissa had ever seen before.

“You two—!” She began in a cold rage, but Harry held up his hands and interrupted her.

“I found Miss Black here after the bookshelf fell over,” Harry quickly said, slipping back into his professorial tone. “Apparently, someone came running past and shoved her aside when she turned to look at them. I believe we may have a student here who isn’t meant to be in the restricted section.”

Instantly, Madam Pince bought his fictional tale. It probably helped that Narcissa was a strong, respectable student who’d never caused her any grief in the past.

“We must find them,” Madam Pince said seriously.

“I was planning to begin a search, but I needed to make sure that Miss Black was alright first,” Harry told her. “Do you recall which way the student ran?”

Narcissa pointed deeper into the restricted section. “I heard them go that way.”

“That’s most helpful,” Madam Pince told her. She was too furious to offer up even a small smile in thanks, but Narcissa didn’t expect anything less from the woman.

“I will see Miss Black out and ensure that the student doesn’t leave the library,” Harry told Madam Pince.

“An excellent suggestion,” Madam Pince replied. “Be sure to check their passes for the restricted section as they leave. I can at least confirm that Miss Black’s is genuine.”

“As can I as I was the one to give it to her,” Harry said. Narcissa glared at him. He nearly chuckled at his double entendre as he said it. “Good luck finding the person responsible for this mess. If you’d like any help cleaning it up, I’d be more than willing to assist.

“No,” Madam Pince shook her head furiously. “They’re my books. I’ll take care of them.”

“Of course,” Harry nodded in understanding. “Well then, Miss Black.” He gestured down the path that would take them out of the restricted section.

They walked together in relative silence towards the exit out of the library. There were quite a few students about who were curious about the chaotic sounds they’d heard, and a few were even claiming to have heard a real woman’s moans mixed in with the cries from the books in the restricted section. Narcissa had to do all she could not to smirk in self satisfaction that they’d gotten away with this.

As they reached the exit, Harry stopped Narcissa and pulled her into a small alcove.

“I’m not done with you tonight,” he whispered huskily into her ears. “Be in my chambers before curfew. We have a lot to catch up on.”

Narcissa shivered in delight. “Yes, professor,” she purred.
