Serendipity

chapter six

no use of y/n, but your general nickname is Meadow. all characters are aged up to be over 18.

pairings: mattheo riddle x fem!ravenclaw reader; platonic!slytherins x fem!reader; platonic!golden trio x fem!reader

warning(s): 18+ content, light smut, oral (fem receiving), fingering, mentions of curses and dark magic

series masterlist; previous part; next part

You both silently stared at eachother, surrounded by the knickknacks in the Room of Requirement.

"You look like you're thinking awfully hard." you say in a teasing whisper.

"I'm trying to figure out if that really just happened, or if the weed has fogged up my brain." he replies in with a huffed laugh. You laugh and step a little closer to him so that you're chest to chest and you stare up into his eyes as you smile. Gods, he was so fucking tall.

I can assure you, it was very real.

He smirked.

So you wouldn't mind if I did it again?

He kissed you with fervour. You felt insatiable; you felt like an addict, longing for more of his touch.

Mattheo. He groaned when you mentally whined his name.

You sound so pretty, sweetheart.

His hands trailed from your hips to your shoulders, until they cradled your face, bringing you even closer so he could deepen the kiss. Then, almost as if he didn't know where to settle them, his hands trailed back down, past your hips to the curve of your bum, cupping the underside of your thighs.

"Jump for me." he mumbles as his grip tightens. You do as he says and he brings your face to his level, causing your arms to briefly squeeze at his shoulders before you loosen them and bring your palms to cradle his face, angling your's to a better position. He groans, moving his lips to the long column of your neck; you tilt your head to the side to give him more access.

You drive me mad, sweetheart. Gods I don't think I'll ever be able to stop.

Then don't. You whimper as his teeth graze a particularly sensitive spot on your neck.

"Tell me you want this." he mumbles, licking and sucking at your sensitive skin.

"I want this- Gods I want you so badly." your reply is delayed as you lose yourself in the euphoric feeling of him. Suddenly you're spun around and dropped, rather unceremoniously, on the plush velvet cushions of the chaise lounge that Mattheo was utilising before you came in; he was towering over you, leaning on his strong forearms that were positioned on either side of your head.

He presses forward and kisses your lips softly, gently trailing them down your chin, to your neck, his body moving to hover over your's so that his hands could toy with the fabric of your blue and bronze tie. Silently asking if he can remove the obstacle in the form of your school uniform and you happily oblige, shoving away at your robe sleeves as he meticulously undoes the knot of your tie. You repeat the same motion with the emerald and silver tie donning his collar and fight to remove the buttons from the holes of his shirt which leaves an open view of his stunningly sculpted abdominals that ripple against supple, tanned skin.

Patience, sweetheart. He says, his voice echoing in every crevice of your mind. Smooth and silky like honey.

He kisses you again before his mouth travels south, his fingers deftly removing your arms from the sleeves of your shirt once he got the buttons undone.

"Gods. You're a criminal for hiding all of this from me, sweetheart." He mumbles into the skin of your collarbone, onyx eyes staring up at you under his long lashes, desire deepening steadily.

You furrow your brows. "What?"

He sucks a deep mark into your skin before soothing it with his tongue.

"Your body is divine, Meadow." he groans as he kisses along the strap of your bra, one hand travelling behind your back and lifting your body up, with your help, so that he can unclip it, with unsurprisingly accurate precision.

Mattheo moves even further down your body, hands beginning to massage the sensitive skin of your thighs as he spreads them apart, flipping the fabric of your skirt up. He's pressing kisses at your naval now, following a path from the bottom of your belly button to the edge of your panties. He huffs a laugh at the fact that you had coincidentally decided on wearing a lacy dark green pair that day.

Piss off. Your voice is a low grumble in the forefront of his mind, which only makes him laugh more. But he sobers quickly, pressing a kiss to where your clit sits under the cover of your panties. He teases you like that for a long minute: presses kisses to and massages the sensitive area, watching you with hawk-like eyes as you squirm under his hold.

Your whines and moans spurred him on, so he continued until you were practically begging for him to do something...anything more.

"What's the magic word, sweetheart?" he teases, his voice a low, taunting rasp.

"Please." you mumble with a whimper. Matt-"

That's seemingly all it takes for his resolve to crack and he practically tears the underwear from your body, throwing up somewhere behind him. Immediately, he buries his face in your core, using his tongue to lap up the wetness that had begun to pool there, thumb brushing sensually against your clit.

Gods. You're so wet. 'S this all for me? You can't see his expression from where he's devouring you whole, but you can feel and hear the smirk in his voice.

"Yes!" He was so good. So effortlessly good that you didn't know if you'd exclaimed out loud or in your head. It was so overwhelmingly good.

He lapped at your centre like you were the first meal he'd had in days, and when you felt a familiar tightening in your core, he seemed to become more feral, transcending from a man starved, to something entirely more alluring.

When he used two of his fingers to scissor you open while his thumb nimbly rubbed fast circles on your clit, you came with a shout, curling over his body, and yanking at the mop of unruly black curls atop his head. He groaned and you keened from the overstimulation as he carried on, speed increasing in fervour as he kissed, sucked and licked at your most sensitive parts.

"Matt- Théo, please! T-too much! Ah!" you were reduced to a babbling and whining mess as he took his fill from you, hands tracing soothing circles against your thighs as he brought you through your climax.

When he finally relented, you were panting from exhaustion, eyes glazed with lust and skin shiny with sweat. When you looked at him, you all but melted into a puddle of desire: his mouth and chin was slick with your cum and he was slowly sucking the fingers he'd had inside you, not thirty seconds ago. Gods he was so fucking attractive.

You weren't even ashamed to be openly oggling him as he used his discarded wand to summon a couple flannels to clean you both up.

"You taste heavenly, sweetheart." he mumbles as he presses another kiss to your lips. You moan when you taste yourself on his tongue. You want more. You want him.

"No. The first time I fuck you will be in a bed, sweetheart. Not some old chaise lounge in the middle of a room that anyone can walk into." he says with a smirk as you narrow your eyes at him, but your face only holds a sort of satiated amusement.

"Get out of my head, you dick." you let out an airy giggle as he flicks your forehead lightly.

It all feels so...domestic. Completely flipping what you thought you knew about him. But you suppose you'd learnt more about him in the weeks you'd spent in his presence than you had in the entire almost six years you'd been at Hogwarts.

You'd never seen this side of him before, however.

"If you tell a soul, I'll have to do unspeakable things to you." he says, smirking as he unapologetically rifles through your recent thoughts, but you find that you really don't care.

"What sort of unspeakable things?" you ask, a teasing lilt to your tone.

He only chuckles, that wicked smirk gracing his features.

"One day, you'll find out, but not today. We need to talk." The serious tone of his voice washes away any of the warm, bubbly feelings you had garnered at his response to a possible repeat of whatever had just transpired. Sobering you up from your lust-driven state immediately.

~∞~

As you both go through the motions of sorting yourselves out properly, you're relieved that the atmosphere, at the very least, isn't an awkward one. Once you're in your uniform once again, creases smoothed out, tie neat and pristine, arms folded across your chest, Mattheo guides you through the meandering trails that littered the Room of Requirement, until you come across something akin to a library – towering bookshelves and a cosy looking sofa, complete with an old mahogany coffee table.

"Sit down, Princess." he says softly, and you do as he says, watching as he walks to the nearest bookshelf and reaches for a book on a particularly high shelf, titled A History of Curses and Dark Magic, Volume Three.

"What are we going to read eachother post-coital stories now too?" you scoff with an unsatisfied scowl on your face.

"Not quite." he chuckles at your put-out expression. "I've spent the last week researching different curses and forms of detecting dark magic." He sits beside you, thigh brushing against your's. "And I think I've found out what's happening to you."

Curiously you take the book from his hand. It was old, heavy. The pages were beginning to brown and tear at the edges, the spine cracked insurmountably.

"What did you find out?" you ask, turning to look at him, to find him staring at the column of your neck, where he'd left a mirage of love bites and hickeys. You smirk as he mumbles a basic healing charm, watching the way his face sours when the marks magically fade away.

"Can you show me what happened when Dumbledore gave you the ring you told me about?" he questions, bumping his thigh to your's. "Open your your mind to that memory, like I taught you."

You do as he says, closing your eyes and allowing the vivid memory to take ahold in your mind, your own voice a distorted echo as you feel Mattheo's presence permeating the memory.

"Interesting." Dumbledore says as he pulls an old signet ring from his deep robe pocket, holding it out for you to take. You watch imperceptibly as Mattheo narrows his eyes on the ring, his ring.

"Can you tell me what you feel when you touch this, please?" Dumbledore's voice echoes in your mind. You do as he says and take the ring into your hands. Twisting it around your fingers, allowing your magic to swirl around it before it burns your fingers. You drop it in an instant. That same cold, tingling feeling you felt when Blaise rotated the necklace washed over you right afterward.

"It's cursed?" you asked, looking up at the Headmaster for confirmation, who is staring at you with knowing, inquisitive eyes.

"Something like that, yes." he says, his decaying hand twitches in response. You watch as the ring seems to vibrate in your lap, something that was amiss to you in the original moment.

You suck in a breathe when you're both forced from the memory. Mattheo is looking between you and the book curiously.

"The way your magic surrounded the ring. It's beautiful." he says. "It's one of seven, you know. I have one and the other five are in the manor."

The signet ring on his hand, that you never seemed to notice before, glints in the dim light of the room, the insignia is identical to the one in Dumbledore's possession.

"Seven rings?"

"No, seven heirlooms. Two rings and five other things that I've never been allowed to touch. They're all quite ugly actually, never had any use for them."

"I don't think the ring is ugly." you say, taking ahold of his hand to bring the ring closer to your face. "It's weird. I felt the energy in the one Dumbledore gave me the second he walked into the room, as well as in the memory itself. This one feels....lifeless."

"The book says it has something to do with different magical cores." Mattheo explains and you nod in understanding.

"You can do wandless magic just as well as you can do non-verbal magic." a statement, not a question. as if he already knows the answer and just wants to hear proof. "But wandless magic takes even the greatest witch or wizard years to master." he continues. "I've seen your development. It took you mere months to master that skill."

"Stalking me now, Riddle?" you tease, but when he doesn't entertain your jokes, your smirk drops. "What are you insinuating?"

"Where do you draw your magic from when you perform wandless magic?"

It's a bit of a taboo in the wizarding world. If you told your friends about the source of power you use, you'd surely be looked at like you were insane, specifically by Hermione who would've surely come across this sort of thing in her mountains of extracurricular reading. But you had grown frustrated when the only progress you'd made upon teaching yourself the throes of wandless magic, was lifting a quill an inch into the air for less than a second. The magic you utilised instead is highly unstable when used incorrectly, and it's borderline illegal in the minds of few people, namely those in the Ministry who specialised in Magical Cores. It teetered on the edge of unassailable power – something most people wouldn't dare mess with.

"I draw it from the air." you mumble, turning away from him, ashamed. "I know it's unconventional. I tried using my own magical core, but it never seemed to work. I did it on accident the first time, but I was successful. Then when I tried again the conventional way, it didn't work. I don't abuse the power, only borrow."

He tilts his head as realisation seems to seep into his features.

"Show me?" he asks, squeezes softly your hand with his large one that you're still holding, unconsciously.

You nod, hesitantly shifting your gaze to the book in his lap. You focus on drawing from the energy surrounding the old hardback, watching as the swirls of your magic, invisible to the boy beside you, intertwined with with potent magic supplied by the Room's core. You felt a rush of power surge through you as the book begin to levitate from Mattheo's lap, only to fly into your awaiting palm. You inhaled sharply at the prickly feeling the magic left coarsing through your veins.

"Incredible." he mumbles as he stares between his lap and the book that you now had in your grip. "And you did that using the magic in the air, not your own?"

You nod. "It always leaves a minute lasting effect afterwards, sort of like a consequence of using another magical source. There has to be a balance. If I do it too much I begin to feel a little dizzy, but I've never fainted like I did in the Wing last week."

"I was right." he mutters to himself, nodding his head, his lips quirking. You raise a brow at him.

"Care to share with the rest of the class?" you question, sarcastically.

"You're a syphon, love."

You sit there for a moment, silently contemplating his words. A syphon. A rare ability among few witches over the centuries; even rarer than a seer.

"How'd you come to that conclusion?"

"I wasn't sure until you showed me how you draw power from the air around you."

When your face drops to a confused frown he draws your body into his, lifting you so that you're sat on his lap, facing him.

"Listen. This isn't a bad thing. It's far from a bad thing. Trust me, sweetheart." he reassures. It's obvious to you that he knows something that you don't.

"What aren't you telling me?" you mumble, hands reaching to mess with the curls at the nape of his neck.

"When its safe for you to know, I'll tell you I promise. But for the sake of saving my friends-"

"And you." you interrupt, but he only shakes his head.

"For the sake of my friends, I can't tell you until the time is right."

"And when will that be? After you ghost me for another week? A month?" you sigh. "Is that what you're going to do when we walk out of here?"

He sighs deeply, his hold on your hips tightening ever so slightly as he brings you closer to him.

"That was a mistake on my part, sweetheart. You make me feel things that I was certain I wouldn't ever feel. I'm truely sorry."

He seals the apology with a long, breathtaking kiss, which momentarily leaves you unable to speak.

~∞~

Some hours later, you're sat beside Hermione at the Gryffindor table for dinner, Harry sat opposite you both. Ron was further down the table with Lavender Brown practically in his lap, the former of your friends sending poorly hidden glares his way.

"How's befriending Professor Slughorn going, Harold?" you ask, taking a sip out of your bronze goblet. After Dumbledore's visit last week, you sought out your three friends and demanded answers regarding Slughorn and Harry. But much like you, Dumbledore wasn't being as straightforward with the Chosen One as he thought he would be, especially after the miscommunication of last year, which inadvertently got Harry's Godfather killed.

"Not brilliantly." Harry mumbled as he stabbed his fork into his chicken.

Hermione scoffed.

"He's completely understating." she said. "It's going abysmally."

"Well, what methods have you used to get the information?" you ask, incredulously. How difficult was it to get information out of a man who spent his free time in the pub drinking away his sobriety?

Harry stammered as he tried to think of a reply and you balked at him.

"You didn't just outright ask him did you? Harry are you an idiot?" He gaped at you as Hermione snickered behind her goblet.

"Dumbledore showed me the half-memory that Slughorn gave him. There's a vital piece of information missing." he cringed as your face morphed into further disbelief. He knew that you knew he'd done the complete opposite of the logical thing to do.

"Don't tell me you tried to play out the memory with him, when Voldemort's own son could have been eavesdropping from fifty feet away?" you snapped, feeling entirely not guilty for dragging Mattheo's name into it. What does that say about the person you've began transitioning into?

"I'm not an idiot." he ignored your deadpan look, shaking his head he rambled on. "I sought him out after our last potions lesson, when everyone had left."

He stopped abruptly, turning to Hermione who, in turn, swivelled to face you.

"Speaking of Riddle," she started. "You weren't in the library earlier when I went to find you. Actually, I haven't seen you since after Ancient Runes after lunch."

"You're name wasn't on the map." Harry accused, eyes narrowing behind his thin wire glasses. "Riddle's wasn't either."

"Why were you in the Room of Requirement with him?" Hermione asked gently, as if she were trying to coax a misbehaving child to fess up information.

Internally, you were beginning to panic; the lies and excuses you'd been sporting for Mattheo's sake fizzling out by the seams. Your heart was irratic and you would've confessed there and then, had it not been for the calming presence of Mattheo's magical core in your mind.

What's wrong sweetheart, you look like you're going to pop a blood vessell.

Charming, Matt truly. You snark and he chuckles in your mind before his presence washes a feeling of seriousness over you.

What's wrong? He's insistent.

They're suspicious of us. Of why we were in the Come and Go room together.

How did they know about that?

That isn't important. You weren't stupid enough to give away one of Harry's best assets. What do I tell them without having to lie. I can't bare to lie again.

He's silent for a moment and you internally curse him as Harry and Hermione seem to be berating you, but you hear none of it, focusing on the pulsing of Mattheo's magic as he takes his sweet time to respond.

Tell them what you were doing. Say that you were annoyed by my avoidance; that it interrupted your schedule; that I was taking advantage of your time.

Harry was in the middle of a they-are-all-Death-Eaters spiel when you interrupted him to finally answer after what had only been a few moments.

"I don't know what you want me to say, Harry. I've been tutoring him since the start of the year. Which you both already knew." you send a look towards Hermione, who shrinks away. "He's been avoiding me all week – Rowena knows why – so I made Theo tell me where he was."

You stifled a laugh when Theo dropped his fork under the deathly glare that Mattheo sent his way.

Behave. You mentally slap him.

He smirked wickedly at you.

"He was probably doing his father's bidding." Harry spat.

"Maybe. But he needs a stellar Ancient Runes grade if he wants Theo to keep him on the Quidditch team. I'm doing Teddy a favour, nothing more." you reassure, and while it was only a half-lie, the guilt ate away at you all the same.

The pair seemed to sigh in tandem before Hermione turned to you, apology written all over her face. The guilt seemed to intensify.

"Just–" she paused, glancing over at the Slytherin table momentarily. "Just be careful will you? I don't want you to get hurt."

"I am being careful Mione, don't worry about me." you smile, but your pretty sure that, and judging by her unconvincing glance shared with your friend, she doesn't believe a word you say.

And after what happened in the Room that could grant you whatever you wished for, you weren't so believing in your resolve either.
