Chapter 3: Service

The bell rang, signalling the end of Potions. Una looked at Sabine and Meredith. Professor Slughorn was in a very pleasant mood after she’d performed well in class today but nerves still twisted in her stomach.

“You’ve got this,” said Sabine confidently and extended her pinky finger. Meredith leaned across the desk behind them and the three of them squeezed their pinkies together. “You know how to get what you want. So do it.”

Una nodded. “I’ll meet you in the Great Hall.”

She braced herself, getting ready to ask her favour of Professor Slughorn. Careful flattery of the people who mattered was right in her wheelhouse but when it came to her brother Graham, her fierce protectiveness made her feel like the stakes were incredibly high.

Cormac McLaggen, who usually ignored her in this particular lesson due to her proximity to the rest of the so-called ‘Vipers’, glanced at her suspiciously as he exited the classroom. Una didn’t acknowledge him. She didn’t need Cormac distracting her now as she hovered at her desk, waiting for the Potions room to vacate.

“Professor Slughorn, sir?” she asked when it was only she and the Potions Master left.

“Miss Montague, I’ve already told you that was an excellent Everlasting Elixir. I hope you’re not looking for more points?” he chuckled.

“No, sir.” She smiled modestly. “I hope it’s not too much to ask but I was hoping to ask you a favour.”

“A favour? Well, I certainly couldn’t refuse at least hearing our Head Girl out, could I?”

“Thank you, sir. It’s about my brother, Graham Montague. I don’t suppose you heard what happened to him last year?”

“I’ve heard rumours, of course. But I’m not, ah, familiar with the whole story, that is.”

Una launched into a dramatic retelling of what happened to her younger brother last year. She didn’t hold back on the horrific details - her eyes expertly welled up in all the right places while Slughorn ‘ooh’-ed and ‘ahh’-ed. By the end of the story, Slughorn had even conjured up an opulent satin handkerchief for her to dry her eyes on.

“And so you see, sir. He’s only sitting two N.E.W.Ts this year - he didn’t want to fall a year behind his classmates. But Potions is his favourite subject. It’s just that he barely scraped an ‘A’ because he missed so much.”

“I do see, m’dear,” said Slughorn sympathetically. “And your brother, is he half as clever as his older sister?”

Una sniffled into the handkerchief and gave him a watery smile. “Yes, sir.”

“Then it’s settled!” boomed Slughorn. “He’ll have some catching up to do - it’s three weeks into term, you know. But he can certainly join the other sixth-years.”

“Thank you, Professor.”

Slughorn smiled and walked her out of the classroom.

“Not at all! Not at all!” he said when they were in the corridor and Una had the distinct feeling that Slughorn very much enjoyed being asked for favours that only he could grant. Like a giant, walrus genie.

Slughorn waddled off into the direction of the Great Hall, as she fixed her mascara, quickly pulling herself together and stuffed the silk handkerchief into her bag. That couldn’t have gone any better if she had tried. She was excited to brag to Sabine and Meredith about how she had masterfully pulled Slughorn’s strings. But she was secretly even more excited that Graham would have another lesson to keep himself busy. Hopefully too busy to help Draco Malfoy with whatever schemes he had planned.

“Masterfully done,” said a voice behind Una as she pulled her gaze from Slughorn and turned to see Cormac McLaggen, leaning one of his broad shoulders against the wall and giving her a slow round of applause.

“I don’t know what you’re talking about,” said Una, fixing her hair by tucking it behind her ear.

“Sure,” said Cormac.

“What are you waiting out here for? Are you spying on me?” Una tossed her hair over her shoulder. “Feeling brave enough to push me up against the wall with all these witnesses?” she asked, looking at the sparse groups of students passing the dungeons on their way to dinner.

“Oh, come on. You loved that and you know it.”

Una pursed her lips not deigning to dignify his comment with a response, however true it was. “Why are you waiting out here, Cormac?”

“Well -” he took a deep breath. “Gryffindor Quidditch tryouts are tomorrow and I was wondering if you wanted to come along and watch?”

Una snorted. She hadn’t expected that.

“Don’t laugh,” he said, giving her an offended look.

“I’m sorry,” she said, regaining her composure. “No, honestly, I am. But how do I put this politely?” She looked at the high ceiling thoughtfully. “I simply couldn’t think of a worse way to spend a Saturday.” This was, at least, the truth. She’d spent enough of her childhood and time at Hogwarts watching her brother play and couldn’t think of anything more dull.

“I just wanted to make up for the other night in the library. Call a truce.”

“By asking me to watch you play Quidditch?”

He shrugged and gave her a cocky grin. “Some people say I look really good in my uniform.”

Una laughed again but this time it was in disbelief. He really was arrogant beyond belief.

“Well, thank you for the exceptionally generous offer but I’ll have to say ‘no’ on this occasion.”

“I just thought you might want an excuse to look at me from a safe distance.”

She couldn’t help her mouth twisting into a reluctant smile. He was nice to look at. And Merlin’s Beard, he was persistent. It was a very strange sort of peace offering.

“Please, Cormac,” she said sarcastically, rolling her eyes.

He took a sharp inhale of breath. “Oh, don’t say that. It’s giving me ideas.”

“What, ‘Cormac’?”

“‘Please’”, he corrected her. “You know if you just saw me play, I’d have you begging like that.”

“In your dreams,” said Una, turning to walk away, hiding how much she was enjoying his audacity.

“Wait, Una. Last chance,” he called to her.

“Are you giving me an ultimatum?” she turned back around and smirked.

“I’m just saying, plenty of other girls in here who are interested,” he lifted up his hands.

“Sure, Cormac. Go ahead and ask one of them to watch you play,” laughed Una, shaking her head at his very transparent attempt to make her jealous. “I’ll see you in Transfiguration next week.”

“Suit yourself.”

And with that, she made her way to the Great Hall, wondering if she might make up some excuse to go and watch. She actually would enjoy seeing what Cormac McLaggen’s shoulders would look like in the Gryffindor Quidditch robes.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A few days later, Cormac McLaggen sat in Professor McGonagall’s classroom, determinedly not looking back at the door in anticipation of his deskmate’s arrival.

“So, how did it go?” asked Una, as Cormac looked up to see her slipping into her usual seat as the buzz from the other students filled the classroom.

Cormac hesitated - he wasn’t sure what exactly had happened at the Gryffindor Quidditch tryouts. The memory was still hazy. It was probably all the adrenaline, he supposed.

“That bad?” she smirked.

He shrugged nonchalantly as if it didn’t bother him. “Reserve keeper,” he said. “Probably just as well you didn’t turn up.”

Cormac felt Una’s eyes on him, surveying him carefully.

“You know, Cormac, it would have looked weird if I’d have gone. It’s not like anyone else in Slytherin would have been there,” she said quietly.

“I get it.”

“Everyone knows I hate Quidditch too. It would have been sus-.”

“Honestly, it’s fine.” He looked at her apprehensively. “Look, I’ve been thinking it’s probably for the best anyway.”

Una grinned at him. “Oh no, are you breaking up with me?”

When tryouts were over, he had spent time thinking about this long and hard over the weekend as his thoughts recently so often turned to Una. “I just think - whatever it is we’re playing at - we should cut it out.”

Una gasped playfully. “Oh my god, you are breaking up with me.”

“Well, obviously not. We were never together. But yeah.” He cleared his throat, bracing himself for her reaction.

Una moved in closer to him. “You’re not slick, you know that, right? This is the oldest trick in the book.”

“Una, it’s not a trick. I’m serious,” he said, turning in his chair to face her. Cormac knew the more time he spent in her company, the more he was experiencing feelings for her. Mostly strong feelings of irritation - she really wasn’t an easy person to get along with. But he was starting to realise that maybe the best way to rid himself of those feelings perhaps wasn’t bending her over, and fucking her until she started saying nice things to him. Maybe.

“You can’t resist me, Cormac. You said you think about fucking me all the time,” she hushed as if reading his mind.

“We both know our friends would cut us off if we started dating each other.”

“Who said anything about dating each other?” Una rested her hand on his knee. Her touch felt like a jolt of lightning. Before Cormac could reply, she slinked off of her chair and crawled under the desk. His eyes widened as he looked down at her on the floor between his legs. Una’s hand travelled further up his thigh as she whispered, “Nobody needs to know.”

Cormac felt blood rushing towards his cock as he looked edgily from left to right to see if anyone else had noticed what was happening. They hadn’t. He looked back down at her on her knees with her lips parted.

He was done for.

“Una,” he murmured. “What are you -”

Her free hand rummaged in her bag and she got up to her seat again.

“Just getting my quill,” she said, putting it on the desk and smoothing her hair as she took her seat again.

“Books and quills away,” barked Professor McGonagall as she entered the classroom. “Today you’ll be turning toads into toadstools.”

Una made to slide off her chair to return her quill to her bag but Cormac gripped her arm and shook his head.

Una smirked at him. “What?”

“You know what.”

“Still getting ideas, Cormac?”

This was even more maddening than when Una was pretending she wasn’t interested in him. Cormac opened his mouth to respond but Professor McGonagall continued.

“Might I remind you that you should be working on these spells non-verbally so there will be no need for talking. That goes for you too, Mr McLaggen.”

Cormac turned in his chair abruptly to face the front but Una just smiled innocently at the stern look on McGonagall’s face.

They didn’t speak to one another as their toads were passed out. Una wrinkled her nose when a particularly fat, ugly toad was placed on her desk. As if merely keen to rid herself of its presence she tapped her wand lazily and it turned into a pretty, red toadstool.

Cormac knitted his eyebrows together and pointed his own wand at his toad, repeating the spell over and over again in his head. It did nothing.

“You know, I could help you,” said Una, brushing her hair from her shoulder and lolling back in her chair.

Cormac sighed. “Go on then.”

“Not so fast. What are you gonna do for me?”

“Are you sexually harassing me, Una?”

“Maybe…” She gave him a flirtatious smile that he almost returned until with a flicker of indignation he remembered why he had resolved to stop flirting back with her.

“Then what?” He whispered. “I admit I want to fuck you so you can pretend you’re not interested and then we start this whole thing again?” He raised an eyebrow. “Una, I can’t keep up. I’m not good with these games.”

“Really? I thought we were having fun.”

He looked at her with a pained expression. “I don’t need this kind of fun.”

Una narrowed her eyes. “Fine. Find someone else. You’d be bored out of your mind.”

“I wouldn’t,” he said.

“Prove it.”

“I will.”

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Almost a week later, Professor Slughorn had invited them to another one of his dinners, which Una still determinedly refused to refer to as ‘Slug Club’. After promising Sabine and Meredith that she’d find out what she could about the next potions lesson, Una and Blaise made their way to Slughorn’s office.

They entered the room to find Cormac McLaggen and Eddie Carmichael amongst the students already seated. Una ignored the empty seats beside Cormac and instead, she followed Blaise to the opposite side of the table beside Hermione Granger and Ginny Weasley.

Cormac frowned when she took her seat but she paid him no mind which only seemed to annoy him more. So much for not being interested in playing games.

An hour or so later, when desserts had magically appeared on the table, Una watched as Cormac tried to make eye contact with the girl on Una’s right as he sucked chocolate sauce from his finger. The girl he’d been eyeing up, Hermione Granger, caught his eye and Una had to stuff an entire profiterole in her mouth to stop herself laughing when she saw Hermione visibly recoil.

Cormac cleared his throat and pretended to find another conversation incredibly interesting as she watched his neck turn scarlet as he looked away. Maybe there weren’t ‘plenty of girls who were interested’ as he had claimed. Although, thought Una with satisfaction, if he was looking for a nice, boring girl then Slughorn’s club was probably the the right place

“You know, Miss Montague. I had been meaning to tell you that it’s been a pleasure having your brother, Graham, in Potions,” said Professor Slughorn once the dessert plates had been cleared and the older students’ wine glasses began filling up.

“Thank you, Sir,” beamed Una.

“I was worried about him keeping up after his incident last year but I needn’t have been!”

A few seats down Una heard a snort of laughter. She turned to see Ginny Weasley stifling a snicker with her hand.

“Think it’s funny, do you?” shot Una, glaring at her.

“I mean, sort of, yeah,” said Ginny, far too boldly in Una’s opinion. “He turned up alright in the end. In the U-Bend, mind.”

Una clenched her jaw. Ginny Weasley couldn’t have been the one who’d done it. She was much too small to have shoved Graham anywhere. But still, the little smirk on her face told her that she probably knew who had.

“He almost died. Thanks to someone in your stupid little club,” said Una bitterly.

“Well, let’s call it even after your Slytherin gang of snitches made sure we all got detention,” Ginny retorted.

“Even? You think that detention -“

“Ladies, ladies. Please. All water under the bridge now, surely?” implored Slughorn.

It certainly wasn’t. Not to her. Nonetheless, she quickly rearranged her face into a smile at Slughorn. She would prefer to have him as an ally, have her think she was the bigger person.

“Certainly, Sir.”

Cormac looked at her with a slightly guilty expression from across the table. She averted her gaze - she had temporarily forgotten he had been part of the D.A. too.

When dinner was finally over and Una had managed to procure information from Slughorn about the next Potions lesson, she and Blaise walked back towards the Slytherin common room together.

“That Ginny Weasley really is a piece of work,” sneered Una. Blaise looked over his shoulder. “She’s good-looking though,” Una added just to see his reaction.

“I wouldn’t touch that little Blood Traitor with a ten-foot broomstick.”

“Blaise, don’t use that kind of language around me or I’ll tell your sister.”

He scoffed. “Fine.”

“And I’ve seen the way you look at her. I know you’re just deflecting.”

“Oh yeah? Gonna tell my sister about that too?”

“No,” said Una carefully and they both came to a standstill. “I wouldn’t tell her... And I wouldn’t tell her if you wanted to use Slughorn’s club as an opportunity to get to know her either.”

Blaise eyed her suspiciously.

“I mean it. I don’t think we can help it if we’re attracted to someone - even if they’re in Gryffindor.”

“Montague!” called a voice from behind them. Cormac McLaggen was on his own, walking towards them.

“What do you want?” asked Una coolly.

“I was wondering if you had written down the Transfiguration homework?” he asked, giving her a meaningful look that Blaise didn’t fail to notice.

“I’m going to the common room,” said Blaise, walking away. “I’ll see you later.”

“Blaise, wait a minute.” Una caught up and stopped him. “This doesn’t have anything to do with what I was just saying.”

She stared at him for a second, trying to read his cool, dark eyes.

“Slughorn held you back because he wanted to ask you a question after the party,” he said quietly so Cormac couldn’t hear. “And maybe in future… he’ll have something he wants to ask me.” He raised his eyebrow pointedly.

Una nodded, not daring to say anything else. She wasn’t sure she trusted Blaise. Or he her. But the less either of them said, the more plausible deniability they both had.

She turned back to Cormac as she heard Blaise walk away.

“What do you want?” she asked.

“Look, it’s about your brother,” said Cormac in a hushed voice. “I just wanted you to know it wasn’t anything to do with me.”

She scanned his face carefully, looking for any signs of deceit. But there were none. “Do you know who it was?”

“I don’t think I can say… I mean, you know Marietta Edgecombe? When she told Umbridge about the D.A. she got horrible acne all over her face spelling the word ‘sneak’. There’s a curse to stop us from saying anything about what went on.”

Una rolled her eyes with all the derision she could muster. “Of course. I wouldn’t want you to ruin your good looks. Those are more important. See you later, Cormac.” She walked away but before she could reach the end of the corridor he called after her.

“It was Fred and George Weasley.” His voice rang out, echoing the names in the deserted hallway.

Una paused. Not quite believing what she had just heard, she turned around slowly to see Cormac squeezing his eyes tight shut, bracing himself for the curse to mark his face “Is it bad? Just tell me,” he said, not daring to open his eyes.

Una walked back towards him to look at his face. It was still stupidly handsome. Even in the dim torchlight of the corridor, she could see he had not been marred by whatever curse he was expecting.

She reached up and brushed her index finger across his cheekbone. Her face was so close to his neck that as she looked up at his face she could smell the expensive, clean scent of his aftershave.

“What does it say?” He said, opening one eye.

She traced letters across his face as she spelt out. “D… I… C…K-.”

“Oh, ha-ha.” He said opening his green eyes and looking down at her, standing in tiptoe to touch his face. “Is there anything there?”

She shook her head slowly. “You really thought you might get cursed if you told me?” He nodded. “That was very brave considering your looks are mostly all you’ve got going for you.”

“You know what? I just did a decent thing - you are so -”

“Kiss me,” she interrupted.

“You - what?”

She looked from his raised eyebrows to his lips. “I won’t bite.”

“Sure about that?” he asked sarcastically.

“Not this time, anyway,” she said, smoothing her hands along his jumper. “Unless you want me to.”

He studied her expectant face. For a second she thought he wasn’t going to kiss her. Until, with a resigned sigh, he tilted his head down and pressed his soft lips against hers tentatively. She pulled herself against his body and kissed him back, tasting dark chocolate and red wine on his lips. When her tongue swiped against his lower lip, he seemed to decide it was safe enough to slip his tongue into her mouth.

He ran his hand through her hair and tugged gently at the nape of her neck, tilting her head back so he could kiss her exposed throat shamelessly. She cupped his head as he did, feeling his dark blonde curls entwined through her fingers.

A door slammed shut in the distance and they broke apart abruptly when they heard footsteps at the other end of the corridor. Their eyes darted towards the door at the end of the corridor nearest them. They both bolted towards it. Cormac recklessly threw it open and they ran inside, shutting the door behind them and leaning against it catching their breath.

Una’s chest rose and fell rapidly in anticipation of being caught. They stayed deadly silent as the footsteps passed and breathed a sigh of relief as they went off into the distance.

Una took in her dark surroundings. It was a disused classroom with empty bookcases and some tables and chairs piled up in a corner. They remained quiet for a few seconds, neither of them daring to bring up what had just happened in the corridor. Una knew she had to get back before before Sabine and Meredith had time to be suspicious.

She turned to look up at him. “We should go. I appreciate you telling me about the Weasley twins. That was really useful information.”

“Useful information?”

“It doesn’t matter. But I mean it, thank you.”

“Happy to have been of service.” Cormac leaned against the door, looking down at her. He curled two fingers under her chin, tilting her head up towards him. “Call it a favour.”

“One I’m expected to return?” she raised her eyebrow. She was well versed enough in getting information to understand the quid-pro-quo involved. “What, you want me to help you with non-verbal spells after all?”

He smirked as his thumb skirted over her bottom lip. “No, the favour I was thinking of involved your mouth. Although you won’t need to be particularly verbal.”

Una’s breath hitched in her throat when she pictured herself sliding her hands down his body and she sank down to the floor and undid his belt. But she quickly turned it into a scornful scoff. “That is very presumptuous of you.”

He gave her an arrogant look that made it clear he had seen the flicker in her eyes as she had briefly considered it.

“Come on, I bet you’re good at it. You’re good at everything.”

She wasn’t sure how to respond. Honestly, she didn’t know if she’d be good at it. Sure, she’d had plenty of clumsy fumbles in deserted corners of the common room with boys, groping and rubbing each other under layers of clothing. But sucking Cormac McLaggen’s dick as some sort of subservient expression of gratitude?

“I don’t get on my knees for anyone,” she said, finally, pulling back from his touch and screwing up her face.

“Oh yeah, what were you doing on the floor in Transfiguration last week? Or maybe I’m not just anyone?”

“You wish. I was getting my quill out of my bag.”

“You little tease,” he grinned. And for some reason, the cocky way he said it made butterflies erupt in her stomach.

“You’re not going to provoke me into sucking your dick by calling me names. You really think I care if you call me a tease?”

“C’mon, I’ve seen the smirk on your face when everyone stares at you in these little skirts,” he said quietly, his fingers lightly touching the hem of her skirt, skating the front of her thighs.

“Not everyone,” Una said in a small voice, a little more honestly than she’d intended.

Cormac’s eyelashes lifted from the hem of her skirt to her face. “If I looked at you, I’d be walking around like this all the time.” He took her hand and placed it just below his belt. He was hard. Her instinct was to withdraw her hand and admonish him but she didn’t. Instead, she kept it there, looking up at him and daring him to continue. “You know, when you started dressing like that - way back at the beginning of our third year - I used to think about kissing you… right here.” He moved his hand under her skirt and dragged his finger across the front of her underwear, sending a pleasant shiver down her spine. “It was stupid. I hadn’t even kissed a girl before or anything yet. All I knew was that every time I saw you, I wanted to bury my head between your thighs and taste you.”

“You… you did?” Una took an unsteady breath, running her fingertips over his hard length from base to tip. She could feel him pulsing under her touch.

“I was hardly getting anything else done. So I just stopped looking at you altogether.” The pads of his fingertips rested just over her clit through the fabric. She felt like she was on fire - so hot and throbbing that she was surprised Cormac hadn’t been scalded just by touching her. “Like I said, stupid of me.”

He kissed her again as his fingers rubbed gentle circles over her underwear, barely touching her. Una let out an involuntary whimper against his lips. He kissed along the line of her jaw and pressed his mouth to her ear, the slightest bit of stubble tickled her face. “See? I can be a tease too,” he murmured, a low growl in her ear that made hairs on the back of her neck prickle.

Shit. He was right. And he was good at it. Una gulped, loud enough for him to hear. He drew back and looked her up and down. The way he toyed with her already had her desperate for him to put more pressure on her aching pussy.

“I didn’t know you even knew I existed,” she admitted, her muscles in her core twisting so tightly they were starting to hurt.

“Well, it was easy to pretend since you have such a terrible personality.”

She exhaled an amused laugh of relief when he made fun of her. This was more in her comfort zone - playful sniping, not confessions of secret pining that made her yearn for him in a way she wasn’t ready to admit. “Speaking of which, I thought you didn’t need this ‘kind of fun’?” Una asked, hoping to provoke him into arguing with her again.

“Who said anything about fun?” asked Cormac, his green eyes glittering darkly.

Without warning, he pressed her against the door with his body and pushed his hips between her open legs. Una winced in surprise. God, she’d been thinking about him doing that every night since he did it in the library. He scooped her up with ease, pinning her against the door as she held onto his shoulders, feeling the friction of his hard cock against her throbbing cunt. Una’s breath hitched in her throat when she felt his hips buck against her and he let out a grunt as his cock chased the pleasant stimulation.

Cormac leaned down and trailed wet, sloppy kisses down the side of her neck again, this time pausing to suck hard on her sensitive skin. Una breathed heavily, tilting her head back against the door and enjoying the feeling of his lips sucking on her neck. Her neck. With a start, her eyes flew open and she tugged his hair, pulling him back.

“Don’t give me a love bite,” she hissed. “Someone will see.” His grin faltered when he saw the serious look on her face. Una loosened her grip on his hair. “Cormac? Maybe this is a bad idea.”

Cormac heaved a sigh and gently let her down until her feet met the floor again. He pressed his forehead against the top of her head for a few moments. The only sound was their laboured breathing as the reasoning part of Una’s brain fought for the blood supply below her waist.

“Yeah… maybe,” he said solemnly. Una could practically hear her body crying in protest, desperate for his touch below her waist again. She had secretly hoped he’d disagree. Find a way to persuade her. “Can I just… do something? I need to get it out of my system.”

“What - oh.”

Cormac knelt in front of her. “I want to taste you. Just once,” he said and pushed her skirt up. Una felt her cheeks burning as he pressed his face against her underwear and inhaled deeply. Shit, what was he doing? She was so turned on, she knew it must be a hot, sticky mess down there. Cormac groaned as he breathed out, sending a ripple of warm vibration across her clit.

“Fuck, you smell good.”

“I smell good?” she blurted.

“What? Nobody ever told you that while they were eating you out?”

She shook her head. Una had never let anyone do this to her before. Not that she’d tell Cormac that.

“Well, they’re idiots,” he said. She was glad that he had misunderstood her meaning. He hooked his fingers over the hem of her underwear. “Can I take these off?”

Una bit her bottom lip. “...I thought it was me who owed you a favour?”

“This is more of a favour from present me to fourteen-year-old me.” He slipped her underwear off and down her legs. She stepped out of them shakily - her legs felt so weak she had to lean against the doorknob for support.

He traced two fingers between her folds, the flat of his fingers sliding against the slick of her hot, neglected slit. “You’re so fucking wet.” She couldn’t quite believe she was letting Cormac McLaggen do this to her. He sucked his fingers so he could taste her juices.

“Oh my god, Cormac…” Una said, feeling scandalised and blushing furiously as he closed his eyes in a blissful state of enjoyment. Her breathing felt stuttered as she watched him slowly withdraw his fingers from his mouth.

“That doesn’t count as tasting you,” he said firmly as if afraid she’d tell him to stop. Cormac pressed his lips against her and furnace-hot heat enveloped her clit as he started kissing her there like he was kissing her mouth. She could feel the texture of his tongue as he swirled it around her clit, making little circles as he did. His mouth was slick - she’d never experienced anything so warm and so heavenly on her skin before.

“Fuck, you taste so good…” He paused between kissing and nodded decisively, looking up into her eyes before turning his attention back to the task at hand. “Yep, I’m going to make you cum on my tongue.”

Una stifled a whine when his mouth met her cunt again. She couldn’t let him know how easily she was already coming undone. She could already imagine how triumphant he’d be, how smug that he’d managed to make her cum so quickly. She had to fight it.

But fuck, his mouth felt incredible on her. She could at least tell him that, right? That’s what people did during this type of thing, wasn’t it?

“Cormac?” she breathed. “That - that feels nice.”

He pulled back, his eyes flicking up from her wet pussy to her flushed face. “Yeah, you like that?” For a split second, she saw his smiling mouth glistening - whether wet with his saliva, her soaking wet arousal or a combination of both she wasn’t sure. God, he really would be insufferable if he made her cum quickly. He kept his eyes locked on her as he pressed the flat of his tongue against her clit.

Una swallowed against the dryness of her throat, unable to tear her eyes away from his wild, intense stare. She felt the pads of his fingers teasing her entrance. Una had been aching for him - any part of him - to be inside her for so long that she could practically hear how dripping wet she was. He raised his eyebrows and she nodded, feeling two large fingers slip inside her. Her leg muscles tensed when they began pressing intimately against a spot that only she had ever touched before, alone in the confines of her own bed.

“God, you’re so tight around my fingers,” he said, pausing his licking to watch his digits slide in and out of her. “You needed this, right? Been a while since you let someone take care of you like this?”

Fuck, he had no idea that nobody had ever taken care of her like this.

He pushed his body closer to her, encouraging her to hook her leg over his broad, muscular shoulder so he could push his fingers in even deeper. He curled his fingers inside her wet cunt, tapping against her G-spot. She wasn’t sure if it was the size of his own hands compared to hers or if it was the fact she was fixed on his green eyes as he touched her, but it felt better than when she did it on her own.

“Oh - fuck,” she whined, feeling his hand and mouth working in sync, pushing and swirling as her core tightened around his digits. The sight of him there made her brain feel like it was going into overdrive.

Every movement, pressing deep inside her brought her closer and closer to the brink. It was coming thick and fast. Faster than she had ever managed by herself. She threaded her fingers through his hair, just for something to hold onto as she trembled but he took it as a cue to pick up his pace.

“Mmh,” he moaned sloppily as his renewed pace made her squirm. Her hips moved as if by their own volition, grinding against his tongue and chasing the bliss that was ready to burst from her core. She in equal parts wanted it to happen quickly and for this moment to last forever. She imagined Sabine and Meredith waiting for her in the dormitory, wondering where she was. As soon as the thought crossed her mind, her pussy started contracting around his fingers as they drove mercilessly into her, pressing again and again and again on that sweet spot in her core without reprise. Fuck, it was wrong that she was enjoying this. So fucked up and so fucking wrong.

“Keep going,” begged Una as the wave pulled back, ready to crash over her. She arched her back and threw her head against the door, tugging on his hair. No wonder he was driven mad by the idea of her being on her knees for him, if this is what it felt like. She wanted him here all the fucking time now. The sound his mouth was making as he kept sucking and licking and fingerfucking her, ignited some deep, primal part of her brain that blocked out all the inner chatter about how they shouldn’t be doing this.

She breathed hard, open-mouthed as she looked down at him again, expecting to meet his gaze once more but instead found his eyes closed in pure, unencumbered pleasure as he devoured her like a starving man.

“Fuck, I’m - ah - fuck,” she sobbed as ecstasy surged through her core.

The dark room turned so blinding white she was sure for a second that someone must have burst through some unseen door and shone their wand light in their faces. But she didn’t care. All that mattered was the orgasm that was rippling through her entire body, so deep that it seemed to burst through all her extremities. His wet tongue continued its attack on her clit and his fingers kept drilling deep into her, guiding her through it until finally, her legs were twitching from the aftershock.

She let go of his hair and practically collapsed against the door, panting wildly as with a smug grin, Cormac disentangled himself from under her leg. “Maybe you were right about not getting on your knees,” he said, coming up to his feet with a groan.

Una pushed herself from the door and threw her arms around his neck, startling him. “No,” she said, between desperate kisses, tasting herself on his lips. “You were right,” she kissed his neck. “You were right. I want to -”

She slid down his body onto the floor, brushing her fingers along his cock. She panted as she looked up at him with wide eyes. It was more than just quid-pro-quo - she wanted to be of service - to make him see just how good she could make him feel.

“Oh, fuck,” he breathed, watching her fingers work his belt. Just as she had unfastened it, they heard footsteps coming along the corridor and both looked at each other in alarm. “Oh, fuck!” he said again, bitterly through gritted teeth.

They heard the footsteps pause outside the door and Una quickly scrambled to her feet as the doorknob turned. She took one look at Cormac’s panicked face, extracted her wand and pointed it at him, casting a silent disillusionment charm.

His body turned invisible, just as the door opened.

“Miss Montague?” asked Professor Slughorn’s voice. Una squinted into the light cast from the lit tip of his wand on her pink face. “Miss Montague, are you alright? I thought I heard-”

“Yes,” she said, quickly, pretending to wipe a tear from her eye. “Crying. I’m sorry, Professor. I just needed a moment alone after that conversation with Ginny Weasley.”

He pouted sympathetically. “Now, now. You mustn’t let these things bother you.”

“Yes, Sir.”

“Come on, then. You wouldn’t want any of the Prefects on corridor duty to catch their Head Girl out of bed after hours, would you?” he chuckled. “A poor example for them!”

Una nodded. Her eyes tried to find Cormac’s faint disillusioned outline but she was glad when she couldn’t see or hear him. She made to follow Professor Slughorn out of the classroom but paused, realising she wasn’t wearing any underwear. Her eyes scanned the floor in a frenzy, looking for them.

Slughorn paused at the door. “Everything alright, m’dear?”

“Yes, I just thought I’d dropped my… handkerchief,” she said pointedly into the darkness.

And so, she followed Professor Slughorn out of the classroom and they parted ways when they reached the end of the corridor so he could return to his office and she could go in the direction of the Slytherin common room. Una could distinctly feel the sensation of wet stickiness coating her inner thighs as she walked.

When she had sneaked back into the dormitory, she was relieved to find Sabine and Meredith already asleep. She crept into bed, sliding under the duvet and wondering whether Cormac had made it back to Gryffindor Tower undetected - but more importantly, whether he’d had the common sense to find her underwear so as not to leave any evidence of their encounter.
