Chapter 4: Flashback – The Third Encounter

If she thought that, after their little escapade, Severus would be more forthcoming, she was sadly mistaken. Oh, she caught him looking at her from time to time, but he would never meet her eye. At times, during potions class, he would stand too close while inspecting her potion, but never did his hand stray to touch her, not once. It was driving her insane! It had been a month already! Halloween had come and gone!

Frustrated, she made her way from the Great Hall to the Ancient Runes classroom. Was she really going to have to initiate again? Did he want her? Or didn't he? Shouting up ahead made her put her worries aside and increase her speed. She hadn't been given the Head Girl position due to her 8th year status, but she still felt responsible.

The sight that greeted her when she rounded the corner made her roll her eyes. A group of Slytherins was facing off a group of Gryffindors, some things really didn't change. The groups were cheering on their 'champions', two boys, third years she guessed, as they were holding a shouting match.

"Enough!" she shouted.

The supporters seemed to have heard her, but the champions either hadn't, or were ignoring her. When the Slytherin drew his wand, Hermione shot a stinging hex at his wrist. The boy dropped his wand with a surprised yelp.

"Enough," she repeated. She was about to say more, but was interrupted.

"What is going on here?"

Hermione shuddered at the sound of his voice. It made the hairs on the back of her neck stand up, and it gave her goosebumps all over. Turning around, she was about to address him, as he spoke again.

"Did I just see you shoot a stinging hex at another student, Miss Granger?"

She frowned. "Yes sir, but it…"

"And are you not aware that magic in the corridors is forbidden, Miss Granger? Did the war addle your brain?"

"No, sir!" she replied in outrage. "It simply was…"

"Detention, Miss Granger," Severus interrupted. "Friday night, 8 o'clock."

Hermione gaped at him. "But sir…"

"Shall I make that two nights?"

Well, actually…, a little voice in her head said. She quickly clenched her teeth. Was he for real? Was this a ruse?

"No, sir," she answered demurely.

Some of the students around her chuckled. Severus whirled on them, invoking his wrath, and dismissing her in the process. Continuing her walk to her next class, her mind once more focussed on his lack of initiative. Or had that just changed? With an annoyed growl, she shook her head, trying to get him out of there, but as always, to no avail.

By the time it was Friday, she was filled with anticipation. Skimming through her trunk, she decided on a black, lacy bra and matching panties. Of course, she had to wear her school uniform, but nothing could stop her from wearing something sexy underneath.

At 8 o'clock sharp, she knocked on the door to the Potions classroom. The door swung open. As she walked into the dimly lit room, she could see him sitting behind his desk, grading papers. A cauldron was standing not far away.

"Miss Granger," he greeted without looking up. The door clicked shut behind her. "You'll be brewing the common coughing cure, the infirmary is running low. I hope you can manage that? Should I write down the recipe, or are you as smart as everybody keeps insisting, and know it by heart?"

Hermione was taken aback by his sour tone an behaviour. Apparently, she had been mistaken, and this was a simple detention. Disappointment seared through her.

"Yes sir, I can make it, and I know the recipe," she answered him, trying very hard not to let her feelings seep into her voice.

"Then what are you waiting for?" He vaguely waved at the waiting cauldron, and continued with his marking.

Hermione dropped her bag next to her working station, and went to the storage room for supplies. Once there, she took her time to breathe. What did he think of her? It had been nice (twice) but now his curiosity was sated? She blew out her breath, and steeled herself for a night of rejection.

However, when she walked out of the storage room and back to her cauldron, she noticed him gazing up at her through his eyelashes. Hope bubbled up inside her, but she squashed it, he might have simply been wondering what was taking her so long.

Organizing her work station, and starting on the potion, she quickly realized that he was, indeed, distracted by her. She let her hair fall in front of her face to hide her smile. So, he was keeping his distance from her? Still fighting the attraction? Hermione smirked, she would make that very, very hard for him.

Schooling her features, she bend to light the fire under the cauldron, keeping her legs straight in the process. For a while, she simply concentrated on the potion, not doing anything in particular to draw his attention. However, each and every time her hand brushed past her skirt, the skirt shortened just a little bit.

When the potion was on a high fire, she waved her hands at her face, faking being hot, and pulled off her jumper. At that moment she was happy for choosing the black bra, it gave her boobs a shadow under the white, cotton shirt. Once the jumper was off, she unbuttoned the top two buttons of her shirt, still waving her hands as if to cool down.

Daring a glance at Severus, she could see he was watching her, his quill hovering above the parchment. Smiling triumphantly, and doing her best to hide it, she set back to work. By the time her skirt was halfway up her thigh, she faked getting annoyed by her hair. She pulled a hairband out of her bag, and set about putting her hair into a bun, making sure to put some extra curve into her spine and make her breasts strain against her shirt.

Glancing once more at her potions professor, she almost laughed as she saw him glaring at her. Oh, she was most definitely enjoying this! Bending over, she took a sniff from the potion, well aware that the position gave him a good look at her cleavage, and the lace bra that covered her breasts. Standing again, she decided to add some more menthol for flavour. With one last sweep, her skirt ended at about a fourth of its original length.

Flicking her wand, she doused the fire under the cauldron. She turned towards Severus, demurely clasping her hands in front of her, slightly pushing her breasts together.

"The potion is ready, sir," she commented. "Shall I bottle it?"

"Yes," he replied, sounding strained.

She turned to get the bottles, wondering what more she could do to make him give in, when his arms wrapped around her, and she was pulled against his hard chest. His touch sent shivers down her spine, oh, how she had craved it in the last couple of weeks.

"You little minx," he breathed in her ear. "Do you really think I don't know what you were doing?"

Her breath hitched at the sound of his voice, so close to her ear. She clasped her hands over his arms, and pressed herself closer to him. His erection was pushing against her bum.

"Hmm, did you enjoy it?" she asked hoarsely.

"You will be the death of me," he whispered in her ear, before running his tongue along the shell of her ear and nipping at her neck, eliciting small whimpers from Hermione.

He gripped her shirt, and forcefully tore it open, causing the buttons to fly everywhere. His hands cupped her breasts, teasing her through the lace of her bra. Hermione arched her back to his touch, secretly loving the dominance he was suddenly showing. She squirmed against his cock, causing him to groan.

Abruptly, he turned her around. Grabbing her bun, he pulled at her hair, and claimed her mouth. His movements were sure, demanding. She moaned as he grabbed her ass and pulled her flush against him.

Suddenly he stepped back, causing Hermione to stumble. She pouted as he simply stood there, looking at her, holding her at an arm's length. Equally as sudden, he seemed to come to a decision. Grabbing her wrist, he started pulling her behind him, through the door to his office, and, to her utter surprise, through the door to his private quarters.

She only caught a glimpse of his living room, some comfortable chairs in front of the fire and a bookcase at the far end, before he dragged her through a hallway and into his bedroom. He practically threw her on the bed. Hermione looked at him in surprise.

Severus smirked, and slowly started undoing the buttons on his robes. The slow progress was driving her crazy with want. His eyes were burning a charcoal black. Inch by inch, his pale skin became visible. Hermione squirmed, wanting to touch him, wanting him to go faster, but instinctively knowing she was to stay put.

She moaned as that enticing line of hair from his bellybutton to his cock became visible. She forgot how to breathe as he unbuttoned his pants. His cock was more than ready. She almost became undone as he stroked himself a couple of times, before leisurely crawling on top of her.

Unable to help herself, she wrapped her arms around him, claiming a kiss, and trying to pull him flush against her. Before she even realised he had moved, he had her wrists in one hand, pinned above her head. The other hand was slowly stroking her side.

"Oh, no, Miss Granger," he whispered in her ear, making her shiver and moan. "You are mine to play with now."

"Oh, Gods!" she gasped, enraptured.

He rumbled in his chest. She could feel something snake around her wrists, and when he let them go, she noticed they were tied to the bed. Tugging at the restraints, she looked at him in surprise. Another smirk was playing around his lips, but she could see he was assessing her reaction. She let out a ragged breath, and mock-glared at him.

He hummed and kissed her. His kisses trailed down, while his nimble fingers pulled down the cups of her bra. Hermione hissed in a breath as he brushed past her nipples.

"Trying to drive me crazy, were you, Miss Granger?" he rumbled against her skin.

The effect of his voice was immediate. She moaned and squirmed, tugging at the restraints in an attempt to touch him. His tongue flicked over a nipple, causing her to cry out and arch into him.

"Trying to get me to lose control?" he murmured, while shifting his attention to her other breast.

Hermione realised she was mewling incoherent sounds, but she couldn't care less. His mouth was hot around her nipple, his flicking tongue sending white hot flames to her centre. His hands were mapping out her skin, drawing fiery lines across her body. She was completely lost in the exquisite sensations he was creating. His mouth travelled upwards again.

"Shall I repay the favour?"

She squirmed as his hot breath skimmed across her neck, making her moan loudly. He licked and nibbled his way between her breasts, down her belly. Hooking his fingers behind the waistband of her skirt, he pulled both the skirt and her panties down.

Slowly, he caressed and kissed his way up her legs, until his hands were on her upper thighs, his thumbs just shy from touching her where she wanted him most. Another cry escaped her as he blew on her wet core.

"So wet, so ready for me," he breathed.

"Please."

The word escaped her, and he chuckled.

"Patience, my dear, patience," he said.

Pinning her hips down with his strong hands, he leisurely started kissing the inside of her thighs, effectively driving Hermione crazy, making her curse and beg. She almost exploded when he finally led his tongue slide through her slit. With long, deliberate strokes, he lapped at her juices, humming as he did so.

"Oh Gods, Oh Merlin, please, Severus, please," Hermione begged.

Finally obliging, he clasped his mouth over her clit, sucking slightly. As he thrust a finger in her, curling it slightly to hit her G-spot, her world exploded into one of the strongest orgasms she had ever experienced. She cried out, arching her back high above the bed, seeing stars behind her eyes. Wave after wave of ecstasy hit her. When she finally collapsed back to the bed, she was panting, feeling slightly disoriented.

Severus wiped his face, and started kissing his way back up her body. She was breathing heavily, looking at him with slightly dazed eyes. He though she was the most beautiful creature he had ever seen.

He stroked her skin while he waited for her breath to calm down, vanishing her bra in the process. For so long he fought his desires for this woman, clinging to their age difference, to the fact that he was her teacher and she his student. Her little act, however, had made him cave. If she wanted him, then he would let her have him, no matter how unbelievable that was in the first place.

Hermione cupped his cheek, and smiled at him, humming under her breath. He kissed her, softly, until she moaned against his lips. He didn't care if it was only sex she was interested in, he would take whatever she offered him, and now, he would make love to her.

As he kissed her, he released the bonds on her wrists. Immediately, she buried her hands in his hair, running her finger through it and slightly pulling on the strands. He moved his kisses along her jawline, until he reached her ear.

"You are so incredibly beautiful," he murmured, before nibbling on her earlobe.

Hermione moaned at his words. One of her hands was now running up and down his back, his skin tingled at her touch. He nipped and licked his way down her neck, feeling triumphant as he hit a particular sensitive spot, and felt her nails dip into his shoulder. She scratched his back as he bit down a bit harder, only to sooth the skin with his tongue afterwards.

Suddenly, her hand found his length. He gasped as she let her fingers skim it lightly. Groaning, he again claimed her lips, more forcefully now. She met him in his passion, taking a firm grip on his cock, and slowly moving up and down.

He transferred his ministrations to her breasts, effectively forcing her to let go of him. He wouldn't last long if she kept that up. Teasingly, he started planting kisses all over her firm breast, deliberately avoiding her nipple. Hermione was writhing beneath him, trying to get him were she wanted him.

"Severus!" she complained, throwing him a frustrated look.

He chuckled, and gave in. As he sucked a nipple into his mouth, she cried out, arching her back, hands on his head. He grazed his teeth against her soft, pink flesh, and revelled in her erratic response.

Repeating it all on the other, equally as tantalizing, breast, his hand skimmed down her side, over her hip, and between her legs. He couldn't supress a groan as his fingers delved between her folds, noticing how hot and wet she was. Another cry escaped Hermione's lips as his thumb grazed her clit and he let a finger slide inside her.

"Severus," she heaved, "Severus, I want you, please, fuck me Severus, I want you now!"

Her words made the fire in his blood burn higher than ever before, and in one fluent motion he shifted his weight between her legs, and buried himself deep inside her. She scratched at his back, wrapping her legs around him and pulling him as close as possible.

"Yes!"

He shuddered out a breath. He could not believe how good she felt around him. Kissing her passionately, he slowly moved back, making her shiver and arch her back, exposing her neck for him to kiss and mark. He tried to keep a slow, even pace, but couldn't keep it up for long. It all just felt too magnificent, too good.

Hermione met his movements, panting with each of his powerful thrusts. The scratches she made on his back were spurring him on. It didn't take long before he was fighting for control, on the verge of falling apart.

"You have no idea how hot you are, woman, how good you feel," he whispered in her ear. "Come for me, come for me, Hermione."

She let out a strangled cry as her walls started trembling around him, pulling him in even deeper. With an equally as strangled grunt, he lost his control at the maddening sensation. He spilled his seed inside her, her name still on his lips.

They collapsed together in a tangled heap. Instinctively, he wrapped his arms around her, unwilling to let her go just yet. With a happy sigh, she buried herself against his side, her head on his shoulder. For a long time they simply lay there, not a word was spoken, there were only fingers tracing patterns on skin, and battering harts trying to slow down.

Severus could feel his eyelids grow heavy. It would be lovely to fall asleep like this, but he knew it was not possible. With the utmost regret he spoke.

"We should get up."

Hermione answered with some nondescript noises, tightening her hold on him. He chuckled at her antics, but insisted.

"We really should get up. Officially, you are still in detention, wouldn't your friends start wondering why you haven't returned yet?"

She grumbled. "I guess."

"Up," he insisted once more, nudging her slightly.

She flopped unto her back. He could feel her eyes on his back as he stood and started redressing. Turning to face her, he rose an eyebrow, and started buttoning his shirt.

"What?" she said innocently. "Can't a woman enjoy an offered treat?"

He glared at her, and she giggled. It sounded like soft summer rain on the roofs of the greenhouses, tinkling, fresh, joyful.

"I think it is only fair I'm offered the same treat, since you so eagerly took advantage of the situation."

Her blush spread from her neck, up to her cheeks, and down to the tops of her breasts. After all that had just transpired between them, he was surprised she would blush about something like this. However, he could see that Gryffindor courage light up her eyes, and slowly she got out of bed. With deliberately enticing movements, she gathered her clothes, and put them on.

She smirked at him, in her skirt and bra, her shirt and jumper still in the Potions classroom. He strode up to her, and kissed her fiercely. Her answer was equally fierce. Breaking apart, he looked into her eyes, before taking a step back.

"Come, Miss Granger," he said, knowing the use of her surname would end their intimacy. "We must find the rest of your clothes, and finish your detention."

He walked out of his living quarters and back into the Potions classroom. Once there he summoned some vials and a ladle.

"I'll portion this out, you go organize the storage room. There are some boxes with new supplies in the corner. You can tell your friends I made you organize by hand."

He watched as she fixed her shirt with an efficient flick of her wand. Amused, he watched several buttons zoom through the room to be reaffixed.

"Yes, sir," she answered, assessing her work and putting the shirt back on.

A pang of sadness shot through him at her formal address, but it was quickly healed by her smile. He didn't know what this exactly was, nor where it would lead, but he would take full advantage of it. He was a Slytherin after all.

Quickly, he portioned out the potion, and cleaned the cauldron and utensils. Hermione re-emerged from the storage room.

"All done."

Unable to resist, he smirked at her, and beckoned her closer. For the last time that evening, he kissed her.

"Don't forget to lengthen your skirt," he murmured against her lips, squeezing her delectable butt.

She glanced down, and blushed again. He realized he liked seeing her blush, it was quite endearing.

"Off you go," he said, after she fixed her attire.

"Bye Severus," she answered, and with a last smile over her shoulder, she left his classroom.
