Severus and Rose parted ways for the afternoon, allowing Rose time to recover from the onset of her hangover.
Rose checked in with her friends at dinner that evening, all of whom seemed to be doing poorly, after which she promptly collapsed into bed.
The next day, Rose overslept, throwing on a tried-and-true outfit and skipping breakfast to rush out the door. She arrived in the potions classroom at eight thirty, her latest morning yet.
She found the classroom candles cold and snuffed out. She moseyed to Severus' office, thinking he might have assumed she was skipping work again.
She knocked on the heavy wood door, and it immediately swung open for her. Severus was reading The Daily Prophet with a steaming mug of black coffee.
"You're late," he chided, still obscured by the newspaper.
The door swung shut behind Rose as she stepped into the office and perched on Severus' desk.
He halved the newspaper, peering at her over it and smirking. "I'll have to punish you."
Rose ignored him, taking his coffee mug and drinking a few sips from it. Severus frowned at her, letting the newspaper fall flat onto his desk. "Please, by all means."
"Do you have any biscuits? I missed breakfast."
His evident discontent remained; however, he waved his wand, summoning a box of dark chocolate-dipped biscuits.
"Ooh, this is the good stuff." Rose said excitedly.
"Only the best for you," Severus said.
Rose eyed him warily, expecting a sardonic look, but he just watched her evenly.
Rose set the mug and biscuits aside, leaning forward to kiss him briefly. "Thank you," she told him.
He grimaced.
"What?"
"Too much, too soon." He responded, turning back to his newspaper.
Rose pursed her lips. "So, your cock in me isn't too much? But kissing you is?"
Severus was reading the newspaper again. "I can't do that here." He responded stubbornly.
Rose, for some reason, interpreted this as a challenge. She took a bite of a biscuit. "Shame, really. I had plans." She crossed her legs, bobbing her foot.
Severus shifted in his chair, but didn't move the newspaper. "Plans?"
"Oh, well." Rose said, finishing the biscuit and licking her fingers languidly.
The newspaper was on the desk now. "Go on," Severus said, an eyebrow arched.
Rose folded the newspaper neatly, setting it aside with the mug of coffee and biscuits, then moved so that she was directly in front of Severus. She pulled him by his collar to her, kissing him slowly. Severus moaned lowly into her mouth, beginning to kiss her more hungrily and sloppily.
He stood up suddenly, pushing her onto her back roughly and spreading her legs. He pressed his body onto her, roughly casting her underwear aside from underneath her skirt and fingering her with three fingers as they kissed. He paused, panting, beginning to unbuckle his belt and unbutton his trousers. Rose stopped him, gently holding his wrists.
"Wait. Sit down," she told him.
He obeyed, and Rose kneeled before him, slowly unbuttoning his trousers.
She paused again, holding up a finger, then disappeared into the storeroom.
She returned in a moment, and shrugged, smiling mischievously.
Severus shook his head, but grinned.
Rose knelt before him again, pulling his cock out from his trousers. She licked it slowly from the base to the tip, pausing at the tip and slowly wrapping her lips around it.
She sunk his cock deep into her throat, the effects of the numbing herb she had swallowed helping. Severus moaned as she took in his length, holding her head with one of his large palms.
Rose began to suck his cock rhythmically, moving her lips up and down his shaft, all the while running her tongue up and down his shaft. At intervals, when she reached the head, she would take it tightly in her lips, paying special attention to it and sucking it.
Rose didn't waste any time, wanting it to feel overwhelming. She kept a quick pace, and it wasn't long before she could feel Severus' leg begin to jerk and heard his breath quicken.
When he came, he moaned deeply, but not loudly, attempting to keep it somewhat quiet (though no one ever frequented the Dungeons, regardless). Rose leaned back on her heels, swallowing his cum and washing it down with a sip of coffee.
She stood, perching on the desk once more, biting into another biscuit.
Severus' hair has somehow become slightly rumpled and a bead of sweat lingered on his temple. He stared at her, mouth agape.
She widened her eyes, blinking repeatedly. "Too much, too soon?" She asked innocently.
He swore under his breath, buttoning his trousers and buckling his belt without responding. He leaned back in the plush armchair, kicking his feet up on the desk. He folded his hands on his chest.
"You have too much power over me," he told her.
Rose wasn't sure if he was joking or not, since he was now very relaxed.
"Not enough, I think," Rose said, leaning on her palm, letting her hair fall in waves across her shoulder.
Severus shook his head somberly. "You have no idea."
-o-o-o-
Rose and Severus spent the rest of the day reading and working in his office in relative peaceful silence, save for a few moments of Rose chatting, Severus nodding patiently.
The next day, Rose arrived at the potions classroom to find Severus busying himself collecting a few vials and jars from the cabinets. He had his sunhat on and seemed like he was readying himself to leave.
"Where are we going?" Rose asked, her pink cloak and dress swirling about her. She had chosen a pink corseted dress, layered with a Victorian-style white blouse underneath.
Severus turned quickly, his eyes slowly scanning her outfit. "You look like a rose."
Rose was caught off guard by this, looking at her skirt self-consciously and brushing it with her hands. "It's fitting, then?"
Severus smirked. "Quite the confection."
He approached her, pausing so that he was even with her. He spoke to her over his shoulder. "We are not going anywhere. I'm going to town for a few things. You'll be sorting and storing the ingredients we collected."
He began to stride off, but halted at the door when Rose responded.
"If I'm not going, then why are you leaving when I'm supposed to start work? You could have easily left a note telling me what to do."
Severus sighed audibly. "Fine. Just walk quickly."
The road from Hogwarts to Hogsmeade was stunning, now that summer was fully blooming. Everything was lush, the remnants of winter finally shrugged off. Dew sparkled on the flowers lining the path, a light breeze moving them.
Severus walked faster than usual; Rose wondered if it was to discourage her acting friendlier than a teaching assistant should be with their professor.
Regardless, she was glad for the fresh air and the outing.
First, they stopped at the market. Severus purchased a few groceries, as well as a pack of frozen mice for Onyx. He paused awkwardly at a display of biscuits and sweets.
"Do you … want anything?" He asked begrudgingly.
"Are you asking if I want a treat, Severus?" Rose whispered conspiratorial.
He scowled. "Never mind."
Rose nudged his arm. "Relax. I'll take a box of those biscuits you had the other day."
He nodded robotically, adding one to his cotton bag.
Rose was becoming ever more aware of how uncomfortable their strange relationship was making Severus. She had thought it was because of their professional relationship, but now she wasn't so sure.
The final stop was a visit to J. Pippin's Potions Shop. Severus and Rose separated without speaking, Rose to peruse the ingredient offerings and Severus to place an order of new supplies and difficult to acquire ingredients for the school season.
The shop had a decent selection of ingredients, with far more local ingredients than the shop she had worked at in London had had. But, there was no replacement for a city shop. Rose began to browse more quickly, looking for errors in spellings or identifications that she could crow over silently.
Meanwhile, Severus was haggling with J. Pippin's great-great-(who knew how many greats?) grandson. She hadn't seen him raise his voice in such an authoritative way before, and was distracted for a moment, watching his large hands gesture. A vein in the side of his neck was more pronounced. Rose wanted to bite it.
As the haggling wound down, she continued perusing, finding a particularly bad error: a complete misidentification of an aster that would greatly alter the effects of the ingredient in a potion.
Severus sidled up to her silently, a box of ingredients in his arms, raising an eyebrow at her inquisitively.
She silently showed him the jar with a smile. He rolled his eyes, smirking, and leaving the shop. Rose replaced the jar and followed suit.
Once back on the cobblestone road, he addressed her. "Well done. Better than most shop owners, it seems." He cast a sideways glance at her.
"Don't flatter me if you don't mean it," she teased.
"I wouldn't dare."
Severus paused as they passed the Three Broomsticks Inn, glancing over his shoulder at the Hogsmeade square clock.
"Lunch? Or maybe the Inn staff have seen too much of you." He grinned peevishly.
"Not at all. They're my good mates," she quipped, stepping ahead of him as he opened the door and slipping inside the Inn.
"I would be too if I saw you in that skirt yesterday," he murmured into her ear, following her closely before brushing past her to find a corner table near a large window.
"This isn't too much light for you?" She asked innocently, inclining her head.
Severus make a face, seating himself, hanging his sunhat on his chair, and running a hand through his dark hair.
Severus caught her studying him from her chair. He raised an eyebrow. "Thoughts?"
Rose smirked. "I don't think you want to know." She studied her nails.
Severus leaned forward onto his arms. "I'll trade you."
Rose considered this, then nodded. "You first."
"Wondering what you'd look like in just a corset, no dress."
Rose laughed, wishing she had worn something a little more lowcut to tease him. Severus leaned back and raised an eyebrow.
"Thinking about getting a ride again … in more ways than one," she said.
Severus shook his head, licking his lips absentmindedly.
"I think I know a place," he said without looking at her.
Rose leaned forward onto her arms. "There's a single-stall lavatory apart from the other lavatories here, you know."
Severus laughed, a rare organic laugh from him. "You're insatiable. Later, Rose. Not now."
She leaned back, exhaling loudly with an exasperated huff, just as the waiter approached to take their lunch order, ending the conversation prematurely.
-o-o-o-
Rose followed Severus into the Dungeons after returning to Hogwarts, but he unexpectedly continued past the potions classroom.
Rose paused. "Are you going to work in your office? Do you want to be alone?"
Severus halted, barely glancing over his shoulder and scoffing. "No, Rose. We're done with work for the day. Follow me."
He began to stalk off, but stopped once more. He turned to her this time, approaching her closely so that she had her back pressed to the cool stone wall. His face was inches from hers.
"Unless you have other plans," he murmured, eyeing her lips.
"You're my plan," she laughed, reaching to pull his face towards her, but he pushed past her, striding down the corridor.
Rose hurried to keep up with him, feeling as silly as she had while foraging for mushrooms in the Forbidden Forest with him.
Severus led her around several turns, so many that she lost track of their progress. Finally, they reached a rounded wooden door, not unlike Severus' office door. He tapped it with his wand, and it swung open quickly.
The room was dimly lit by a multitude of candles, placed in iron candleholders mounted on the walls. The room was dank and damp, and Rose was startled by a few puddles as she entered and closed the door.
There was nothing in the room except chains attached to the wall parallel to the door.
"What, are you going to murder me here or something?" Rose teased flatly.
Severus turned quickly, recoiling as if he'd been struck.
"Why would you —" He began, but stopped when he saw Rose's mischievous smile.
"Not all Slytherins are evil," he said calmly.
"I don't know, Severus," she said, approaching him quickly and gripping his collar. "I can think of some dastardly things you could do to me."
Severus smirked. "Precisely." He said, pulling away and waving his wand quickly. Suddenly, the room changed: moss carpeted the stone floor and ivy clung to the walls artfully. The candles lining the walls remained, but their numbers doubled, and their flames brightened, warming the cold room.
The chains on the opposite wall doubled and a small stone ledge marked the center of their configuration.
Rose was awestruck. "You … planned this?" She approached the chain cuffs, their metal carefully lined with a plush velvet now.
Severus watched her carefully. "What do you think?"
Rose laughed nervously. "I'm not sure if I know this Severus."
"Don't toy with me," Severus growled from behind her, shadows obscuring his face.
Rose turned, smirking. "Would I ever do such a thing?" She approached him slowly, touching his face lightly. "To Professor Severus Snape?" She whispered, emphasizing each part of his name slowly.
Severus moved backwards as she approached him, matching her steps. She stopped when his back was pushed against a wall, a curl of ivy falling across his shoulder.
His hair had fallen across half his face, but he watched her evenly, his head inclined.
She pushed her body against his, letting her lips hover over his neck. His breath quickened, but he didn't move. She kissed lightly on his neck, before biting, hard, and sucking. He moaned loudly, taking her waist in his large hands.
Then, as if he had reached his limit, he lifted her over his shoulder in a fluid motion, walking her to the stone platform surrounded by chains and setting her onto it.
He paused, running his hands up and down her thighs slowly, and gazing at her.
Rose laughed. "What?"
"Do you want this?" He asked softly.
Rose licked her lips languidly. "I think I need a little punishment, don't you?"
Severus gave her a strange look that she couldn't decipher. "Or worshipping."
Rose started to respond but was cut off as Severus lifted her off the platform once more, spun her around, and began to quickly untie her corset. He removed her corset, then unzipped her dress, lifting it gently over her head. He lifted her onto the platform once more and paused, taking in her undergarments.
He raised an eyebrow. "Emerald lace?"
Rose offered a gartered leg out to him. "For you," she said.
He took her leg in his hands, kissing from her knee to her thigh.
He looked up slowly, resting his cheek on her thigh, his hair splashed across her.
"I prefer you in pink," he murmured, her undergarments suddenly shifting to a pastel pink. Her bra, panties, and garters now had small, bright pink bows on them, with small pearls woven into the fabric.
"How did —" Rose stuttered. "What charm is that?"
Severus smiled sleepily. "One only for you."
He turned his head back to her thigh, kissing gently, then begrudgingly pulling away from her.
He held out his hands.
"Wrists," he commanded, gazing at her gravely.
"Yes, Severus," she whispered.
He smirked. "Good girl," he said, latching her wrists into cuffs attached to the wall. Rose giggled, but stopped when Severus cast a serious look at her.
"Knees?" He paused. "But first …" He slowly slid the panties from her hips, tucking them into his belt. He resumed his work, taking her knees and locking her lower thighs into another pair of cuffs.
Goosebumps appeared on Rose's skin at the feeling of cool air now touching her core. Severus tapped the platform with his wand so it held no extra space, and so that a stone lip wouldn't stand between them.
Severus moved closer to her, and Rose felt her pulse quicken, her chest beginning to rise and fall rapidly. Severus noticed, running his hands along her waist and to her breasts, unclasping her bra and tucking it into his belt.
He held her waist tightly. He surveyed her, his eyes rolling slowly from her core to her face.
He swore under his breath, shaking his head, then began to kiss her breasts. He took her nipples in his mouth, lapping them with his tongue, then biting them gently. Rose gasped, shocked at this sudden intense touch. His fingers found her core, thrusting slowly.
Rose began to moan, and Severus moved towards her cunt, kissing her body. He continued to finger her, now licking quickly at her clit. Rose began to shake, convulsing with pleasure and moaning Severus' name as she orgasmed.
Severus pulled away, his hair sticky with sweat. He licked his fingers, then unzipped his trousers, removing his member.
"Holy fuck," Rose swore.
Severus smirked. "Problem?"
"I've never seen a targeted enlargement potion do … that." Severus' member was longer and thicker, even his balls chunkier.
"Can you take it?" He asked, eyeing her carefully.
"Let's see," Rose taunted. "I'm yours to play with."
Severus emitted a low moan, entering her slowly. He paused, halfway inside of her.
"More," she begged.
"All of it?"
"Yes," she groaned.
Severus thrust deep into her, starting slowly, but picking up pace as Rose began to moan louder and louder, begging him to pump harder. His right thumb found her clit while he thrusted, idly tracing circles.
Sweat dripped from his forehead down his large nose. He felt Rose began to shudder beneath him, her knees shaking the chains. He felt her shake then stiffen as she came. He came quickly after, thrusting deep into her and filling her.
They panted silently, until Severus finally removed his cock from her. He collapsed onto the floor, leaning against the stone wall. Rose's cuffs unlocked, and she hopped down from the platform, sitting beside Severus.
He cast her a sidelong glance. "Shall we go again?"
Rose blinked. "Again?"
"That enlargement potion has more than one effect."
