Chapter Text

Remus’ skin was crawling. 

The full moon was just days away and Remus could feel the gut wrenching pull becoming stronger the closer the date got— the closer Moony got to the surface. 

This wasn’t a new experience— it’s one that he’s dealt with for nearly twenty years since he was attacked by Greyback when he was four. 

The short fuse. 

The aggression. 

The need to take. 

Honestly, Remus wasn’t even sure how Regulus dealt with him every month. 

It’s been a rule since they got together— don’t tempt Moony before the full, and it’s a rule that Regulus has adhered to religiously since they began dating nearly five years ago. 

Sweet, lovely, patient Regulus who doted on Remus in his own soft and quiet way— making his tea in the mornings and drawing a bath at night to help the ache in Remus’ hip as the moon crept closer to reaching its peak. 

Remus already had a ring picked out, just waiting for the right moment to ask. 

That goes to say— the moon this month was making Moony more restless. 

Closer to the surface. 

Remus, to his credit, was keeping Moony in check for the most part. He wasn’t snapping at anyone, and despite the October chill that promised stiff joints as well as aching muscles, he was managing quite well. 

Until this point at least. 

Remus glanced up from where he was reclining in the armchair of the living room in the flat he and Regulus shared, the cold air creeping in briefly as Regulus quickly shut the front door. In his hands was a brown paper bag, crinkled from where Regulus had been holding it with the logo of a costume shop printed on the front. 

“Find a costume for Sirius and James’ party on Halloween?” Remus asked, taking in Regulus’ bright eyes and soft smile as his gaze met Remus’, cheeks still pink from the cold. 

“I did. Evans helped me pick it out, actually,” Regulus said matter of factly. 

Remus raised a questioning brow, glancing once more at the brown bag. “Did she? You know it’s alright to call her Lily now, right?” Remus teased lightly. 

“I know— but would you like to see it?” Regulus waved off, shifting his feet like he always did when he was up to something. 

Remus was immediately suspicious. 

Remus’ gaze narrowed slightly. “Sure, darling. Why don’t you show me what you got,” he encouraged, folding the corner of the page in his book and closing it. 

Regulus glanced at the dog eared page and wrinkled his nose, but didn’t comment on it. 

Remus now knew Regulus was planning something. 

“Why don’t I try it on for you instead?” Regulus said sweetly, twisting his hands on the bag and making the paper crinkle further. 

“Regulus—” Remus began, tone laced with warning and feeling as if he were being set up. He felt Moony in the back of his mind, awake and watching through his human counterpart with intrigue.

“It’s just a costume,” Regulus said innocently before disappearing down the hall to the bedroom. 

The thing is, around this time of the month, Remus’ patience was very, very thin. He could hear the bag being opened from where he sat in his chair, the soft rustle of fabric and zippers as Regulus changed into whatever he bought. 

Remus couldn’t wait any longer despite it being only two minutes since Regulus disappeared into the bedroom. 

He stood, curiosity getting the best of him, as he strode down the hallway, the aches in his joints far from being in the forefront of his mind. His hand hovered over the doorknob, listening to Regulus moving around the bedroom before he turned it, pushing the door open. 

Remus practically heard the growl Moony emitted in his mind, unsure if he made the noise himself. 

Regulus turned around, tying two little red ribbons together at his throat. He glanced up at Remus and performed a little spin as if he weren’t intentionally provoking the wolf that was simmering below Remus’ skin. He could practically feel Moony prowling in the back of his mind as he took in his boyfriend's costume. 

Remus wanted to tear the fabric to shreds as a primal need rose in his gut. 

The need to take. 

And Regulus knew what he was doing— Lily knew what she was doing when she steered Regulus into the direction of Little Red fucking Ridinghood. 

Regulus had a soft looking white blouse on that had billowing sleeves and an opening in the front that was laced and loosely tied, exposing the pale skin of Regulus’ sternum. The blouse was tucked into a short black skirt that ended just above the middle of Regulus’ thighs, over the knee black socks covering the rest of his lower legs. He had on a short red cloak that ended where the skirt did, crimson fabric loose and the hood pulled over Regulus’ black curls— but what did Remus in was the waist-cinched corset. 

Regulus already had a soft dip in his waist— Remus loved grabbing it while he and Regulus had sex. He loved the way it flared into his hips and the soft curve of his thigh, but truly, Regulus was a tiny little thing compared to Remus. 

However, his waist in the corset was sinful and it flared the carnal desire to devour Regulus whole.

“What do you think?” Regulus asked softly, twisting his rings anxiously he had plated in fake silver so he could hold Remus’ hand. 

Moony was gnashing his teeth, wanting to take a bite and Remus couldn’t exactly blame him. 

“I think you’re playing a dangerous game, Regulus,” Remus said slowly, trying to keep himself and Moony in line as the primal urge to fuck Regulus senseless was slowly overtaking him. 

“Lily told me all about the muggle fairytale it came from— I thought it was perfect since you could be the big bad wolf,” Regulus drawled, lashes fluttering as if he wasn’t disregarding the number one rule they established when they began dating. 

Regulus’ confidence from watching Remus’ reactions was growing, and Remus wasn’t sure if he could stop himself if it continued.

Remus took a step forward. 

“And what was the number one rule about the wolf that we agreed on, little red?” Remus asked in a low voice, forcing himself to take measured breaths as Regulus stepped forward as well. 

The scent of tea and mint leaves flooded Remus’ senses and it took everything in him to not devour. 

“Don’t provoke the wolf,” Regulus hummed, glancing down before back up to meet Remus’ intense gaze as he inched closer. 

“So what do you think you’re doing, Reg?” Remus grit out, the closer the younger man got the harder it became to ignore the wolf gnashing in his mind. 

“Provoking the wolf,” He murmured, reaching up and dragging a slender finger down Remus’ jumper clad chest. 

Remus grabbed Regulus’ wrist in a bruising grip, yanking him flush against him before using his free hand to tilt Regulus’ chin up as he leaned down to look into silver eyes. 

“I don’t think you know what you’re asking for, pretty boy,” Remus growled low in his throat, Moony clawing to break free— the tension between them palpable. 

“I know what I’m asking for, Rem,” Regulus breathed, attempting to lean up to kiss Remus, but Remus adjusted his fingers to grip Regulus’ chin so he could hold him still. 

“You can’t handle Moony, Regulus,” Remus said firmly out, every thread of control he had fraying as he pressed his thumb to the center of Regulus’ bottom lip. 

“I can handle him,” Regulus whispered, voice steady. 

“You can’t—”

“I read werewolves have a knot when the moon is close to being full,” Regulus interrupted, his voice dripping with sin. “Do you have one?” 

Remus was momentarily thrown by the question, furrowing his brow slightly. 

The thing is, Remus was very firm that for the week leading up to the full they didn’t have sex due to Moony creeping closer and closer to the surface, so the conversation of Remus even having a knot never came up once. 

He was too afraid he might accidentally hurt Regulus to even think about it.

“Of course I do,” Remus said warily, eyes searching Regulus’ face as he silently asked for clarification on why Regulus wanted to know this bit of information.

Regulus hummed, pressing closer to Remus as his eyes drooped to only being half lidded as he glanced up, lashes fluttering as he ran his hands up Remus’ chest only to tangle in Remus’ sandy locks. 

“I want your knot,” Regulus whispered sultrily. 

Remus let out a low noise, forcing himself to do the responsible thing before his composure fell apart. 

“Colour?”

“Green.”

Remus’ control snapped. 

He grabbed Regulus by the waist, lifting him and walked the few steps to the bed before tossing him down in the middle. Regulus made a soft, surprised noise as he propped himself up on his elbows, watching as Remus moved with predatory intent. 

Regulus shivered, taking small controlled breaths as he saw the dangerous glint in Remus’ eyes. 

Remus crawled onto the bed, movements slow as he hovered over Regulus, untying the red cloak and pushing it off Regulus’ shoulders before tearing open the shirt. 

A soft gasp left Regulus’ lips as Remus’ hands slid up his chest, one staying to roll Regulus’ nipple between his thumb and forefinger as the other hand tangled in Regulus’ hair and yanked his head back.

“There is no huntsman to save you this time, little red,” Remus mused darkly before kissing Regulus harshly, biting his lips until they parted for Remus to slip his tongue into Regulus’ mouth. 

His hand slid down, the other still in Regulus’ hair, and ran along Regulus’ thigh, pushing up the skirt as a soft whimper left the younger man’s lips. 

Remus kept pushing the fabric up until his fingers brushed lace, pulling back to glance down. 

“Knickers, little red? How long have you been plotting your nefarious intentions, hm?” Remus murmured, sliding a hand up to cup Regulus’ cock and squeezing. 

“S-Since the summer— I just didn’t know how to bring it up,” Regulus whined softly, bucking into Remus’ hand. Remus tutted, squeezing a bit harder just to hear Regulus whimper, Moony howling in delight in his head. 

“Naughty little thing. You wanted the wolf, you’ll get the wolf,” Remus growled out before replacing his hand with his knee, leaning back slightly. “But first I want you to rut like the needy little bitch you are and show me how much you want it.”

A breathy moan fell from Regulus’ lips from the degradation and pressure, cheeks pinking as his eyes fluttered, steadying himself before grinding his cock against Remus’ thigh. 

Remus smacked Regulus’ thigh hard, heat rising to the surface of the skin as it began to redden. 

“You can do better than that,” Remus taunted Regulus who made a small desperate noise as he began to hump Remus’ thigh. 

The lace provided an additional layer of friction to Regulus’ already leaking cock. Remus looked down with dark satisfaction as he pushed the skirt the rest of the way up, hands settling on Regulus’ hips. 

“Look at your needy little prick making such a mess. I haven’t even touched you properly yet, little love. All this from just rutting on my leg like the slut you are— just a bitch in heat,” Remus murmured, spurring Regulus’ movements as they became more frantic. 

Regulus was truly normal sized and Remus looked down to admire the way the tip of Regulus’ cock was leaking profusely against the hipbone it was pressed against due to the elastic of the underwear.

Remus was just bigger. 

“Sir—” Regulus whined, chest heaving. 

“Can’t even speak properly already?” Remus chuckled with dark amusement. “Is your little cock sore and aching? Does it need attention?” 

Regulus could only make a strangled noise, Remus leaning to the side ever so slightly to pull his wand from the bedside table.

Remus murmured under his breath an intricate little spell he found just Regulus’ movements turned sloppy the closer he got to release, causing Regulus to cry out sharply. 

A familiar, but invisible, pressure circled the base of Regulus’ cock, restricting his ability to cum as Remus stilled Regulus’ hips. 

“Remus— please— I was so close— s’il te plaît—” Regulus sobbed, breath hitching as tears gathered and spilled down his cheeks. 

The sight made Moony purr with delight as Remus took in the spit slicked lips and heaving chest of the man beneath him. Regulus’ black curls were splayed around his head, eyes big and slightly glassy.

Remus always thought how Regulus’ eyes glittered like stars when he saw the light reflecting them, especially when he cried, but all he could think was how tonight they resembled the moon that was pulling at his skin. 

Regulus was pure submission.

And now Remus was about to be Regulus’ ruin and Regulus was glad to surrender to it. 

The silence hung in the air, the only noise being Regulus’ little whimpers as he slowly came back down from the edge due to the magic keeping his orgasm at bay. 

“Colour?” Remus whispered. 

“V-vert,” Regulus whimpered brokenly, already wrecked. 

“Pathetic,” Remus scoffed as Regulus’ cheeks flamed red.

“Sir—” Regulus began with a needy whine, but he wasn’t given an opportunity to finish his sentence as Remus gripped Regulus’ waist roughly, flipping him over and yanking his hips up to force him onto his knees. Remus pressed a hand to Regulus’ upper back to force his chest into the bed and face into the pillows before flipping the skirt up and admiring the way the black lace covered Regulus’ fluttering hole. 

Remus needed more. 

Moony needed to claim. 

Remus barely remembered to cast cleaning charms before he gave in. 

In one motion, Remus tore apart the flimsy lace of the knickers, fabric dropping to Regulus’ knees as Remus spread Regulus’ arse cheeks only to lean down and press his tongue flat against his hole and gather a taste for himself. 

Moony practically howled in delight at the heady flavour of just Regulus. 

Remus and Regulus both moaned— Remus in content and Regulus in pleasure as Remus circled the ring of muscles with his tongue. Drool already began to gather and pool down his chin as animalistic need to taste— no, to consume overtook him. 

Regulus was practically clawing the sheets, pushing his hips back yet writhing under the assault of Remus’ tongue.

Remus’ hands went to Regulus’ hips, stilling him as he curled his tongue, pressing the tip ever so slightly just to create some pressure against Regulus’ entrance. 

Regulus turned his head with a whine, thighs trembling as Remus finally dipped his tongue in for a better taste. A deep rumble of satisfaction emitted from his chest as the tight muscle gave in and allowed him entry. 

“Rem— Remus— I need to cum,” Regulus begged, voice cracking on the last word as Remus ignored him, his own cock throbbing in his trousers against the zip. 

Regulus let out a small sob, little whimpers leaving his lips as Remus had his fill. 

He pulled away just as he felt Regulus begin to tense, not even allowing a dry orgasm as Regulus made a noise of frustration. 

Remus looked down as Regulus gripped the sheets, barely able to glance back as he shook with need. 

Desperate.

Regulus was useless, only being able to watch as pathetic needy noises fell from his lips as Remus pulled his jumper over his head, and murmured under his breath as he pressed a finger inside Regulus. 

“Fuck—” Regulus gasped, his knees widening just a fraction despite his legs having turned useless ages ago. 

“I’m going to fuck you,” Remus said darkly, watching how Regulus keened softly and tried to regulate his breathing, “I’m going to fuck you are you’re going to take it and only then decide if I’ll give you my knot.” 

“Oui, s’il te plaît,” Regulus groaned softly, pressing back as Remus pressed another finger into him, his mind blank as he babbled. “Je veux ton nœud. Je veux que tu me remplisses,” he whined. (I want your knot. I want you to breed me.) 

Remus paused as Moony thrashed in his mind, wanting to take control. 

“You want me to breed you, little red?” Remus confirmed, positive he heard the plea correctly as he leaned down over Regulus’ back, lips brushing the shell of Regulus’ ear. 

“Oui—”

“Want me to stuff you full of my pups?” Remus growled out, beginning to thrust his fingers again, rougher than before as he curled them slightly to press against Regulus’ prostate. 

Regulus cried out, nodding frantically as he rocked his hips back against Remus’ hand. 

“Please,” Regulus choked out. 

Remus raised his other hand, chest still against Regulus’ back and landed a sharp smack to the side of his arse, eliciting another keening noise from Regulus. 

Remus added a third finger, continuing to press against Regulus’ prostate with each thrust as he came apart beneath him, the blouse barely covering his shoulders anymore, untucked and slipping out from beneath the loosening corset. 

“Beg,” Remus whispered against Regulus’ ear.

“Please, please— Remus, please give me your cock. I need it—”

Remus smacked Regulus’ thigh again. 

A red hand print painted the milky white skin before Remus ran his hand along the inside of his thigh down to the knee high socks and back up to his arse, massaging the soft flesh briefly, as he nipped at Regulus’ neck. 

He needed to feel the warmth of Regulus’ skin heat under his touch as he continued to work his fingers inside Regulus with his other hand, unrelenting and needing more.

“You can do better than that. Otherwise, I’m keeping your pathetic little prick locked and throbbing all night,” Remus murmured as Regulus made a wounded noise. 

“Please breed me. P-Please, I’ll be so so good. I’ll be a good boy. I’ll take y-your knot— a-and I’ll be a good slut and you can use me,” Regulus pleaded, voice pitching a bit high with desperation as Remus pressed once more into Regulus’ prostate before withdrawing his fingers as Regulus tensed.

Regulus was a mess of tears, precum leaking on the sheets below him and hair mused— the perfect image of debauchery and submission as he trembled having been denied yet another orgasm. 

Regulus was the sacrifice while Remus was the wolf in sheep’s clothing, ready to reap his reward for being patient enough to break Regulus down to nothing but need and whimpers.

It was beautiful and intoxicating, Remus leaning down to drag his tongue from Regulus’ chin to his cheek to taste the salt of falling stars that couldn’t bring light to the depravity thrumming under the surface of his skin. 

Take. 

Remus sat back up behind Regulus, eyes fixated on the way Regulus’ hole clenched around nothing, waiting to be filled as he unbuttoned his trousers and pulled down the zip. Remus pulled his cock from his pants, already throbbing and slightly curved, veins outlined along the shaft as he gave himself a brief stroke to smear the precum along his length.

He barely got his pants around his thighs with his trousers as he mumbled the lubrication charm and pressed the tip against Regulus’ fluttering hole.

If he hadn’t been with Regulus for so long, Remus would have been terrified he’d break him.

He knew better than to second guess what Regulus could handle despite his earlier reservations. 

“Mine,” Remus snarled before pressing in, Regulus’ back arching as he let out a gasping, pitched moan— fingers curling in the sheets and the muscles in his shoulders flexing as Remus bottomed out in one motion. 

The feral beast inside Remus’ head took over as he gripped Regulus’ waist, fingers brushing the fake, costume leather of the corset and digging in just to feel the cheap material tear from his nails.

Remus barely waited to draw back and begin pounding into Regulus at a deep, but brutal pace. 

“So fucking tight for me, darling. Take every inch of me,” Remus groaned, grip tightening enough to surely leave bruises. 

Regulus did gladly— happy to choke or beg for it. 

Each breath that left Regulus sounded like the air was being punched out of him as Remus roughly fucked into him, jerking his body back each time he thrust forward. 

Regulus tried to form words, lips trembling as Remus seemed to lose part of himself as Moony took over. 

“So— fucking pretty like this, little red. Such a pretty little thing— taking my fucking cock like a good. fucking. slut,” Remus ground out, accenting his words with each piston of his hips. 

“R-Rem,” Regulus managed, Remus’ name choked out high pitched and needy as his brain tried to formulate words. He was overwhelmed in the best way possible. Each stroke inside ignited his skin, burning him from the inside out as it consumed him as his hole tried to pull Remus in further. 

Remus growled, hand tangling in Regulus’ hair and yanking him up off the bed and against Remus’ chest, a broken noise leaving Regulus’ lips. Remus slid his free hand up, lips pressed against Regulus’ ear as he slipped two digits into Regulus’ mouth and his thighs shook as he was held up. 

“Just take it,” Remus whispered hotly against Regulus’ ear, breath labored. “Take it like the good boy you are and let me breed you full.”

Regulus moaned around the fingers, the new angle pressing into his prostate with each thrust as his cock leaked messily against his thighs— swollen, red, and desperate for release. 

He was light headed from it all, dizzy with the pleasure as he drooled on Remus’ fingers, tongue trying to swirl around them and suck. His eyes were half lidded as Remus continued to snap his hips up into Regulus. 

All he could do was take it, Regulus completely blissed out and pliant, getting exactly what he wanted while there were no more coherent thoughts in his head. 

The only thing he could focus on was Remus’ cock and the burning need that was making stars burst behind his eyes. 

The hand from Regulus’ hair drifted down, ghosting over his throat and pressing there. Remus didn’t squeeze, but simply displayed the act of dominance before sliding down to grasp Regulus’ hip to pull Regulus back against Remus’ cock in a bruising grip. 

Regulus vaguely registered that his skirt was bunched up above the hand holding it up, but he also knew that the skirt wouldn’t survive this.

“Gonna fill you, little red. Show you what it means to take the wolf,” Remus snarled, but Regulus didn’t fully acknowledge it as he went cock drunk. 

Regulus moaned, drool dripping down his chin and Remus’ hand as he felt himself begin to stretch further as Remus’ thrusts became more merciless— more erratic. 

The knot.

Regulus’ head fell back against Remus’ shoulder as Remus’ cock began to swell, his knot forming and stimulating Regulus’ prostate each time Remus drove up into him. 

“Tell me you’re mine,” Remus muttered darkly, each time Remus’ cock brushed his prostate making Regulus practically see stars.

“Y-yours—”

“Who owns you?”

“You— youyouyou—” Regulus choked out, slurring around the fingers in his mouth as a couple of tears slipped down his face. Remus moaned in his ear at the slight, tongue darting out just to taste Regulus’ tears again and savor the sweet, salty taste of them.

“Such a pretty boy— fucked out from my cock and crying for it,” Remus breathed, voice becoming airy as he gets closer to his own climax. “Fuck— cum, Reg. Cum on my cock while I breed you full of my pups,” Remus groaned, waving his hand and the pressure around Regulus’ cock releasing. 

Regulus could feel himself being stretched wide as Remus’ knot caught on his rim with each thrust now, threatening to lock as he let out a sob— his abdomen tightening as he felt himself clench around Remus. 

Regulus saw white, every cell lighting up as he burst into what felt like stardust as he finally came messily not only on the hiked up skirt, but his thighs and the wrinkled sheets below him. Remus growled and bit down on his shoulder hard enough to break the skin as Regulus let out a broken sob from the force of it all, going limp.

Remus’ knot finally locked in place, stilling inside Regulus as warmth spread inside him, Remus’ cock pulsing as he came inside Regulus. 

“Take it, take it all, Reg. So good for me,” Remus murmured, nuzzling Regulus’ neck as Regulus slumped back into Remus, chest heaving and his vision returning as he blinked rapidly despite the euphoric cloud he was currently floating on. 

He could barely register that the fingers had left his mouth, connecting his lips to the digits by a thin string of saliva. 

Remus felt the satisfied rumble Moony emitted as the need to claim and breed was satisfied. 

Regulus could feel the couple drops of cum that escaped around the knot dripping down his thighs as Remus gently laid them both down after managing to get his trousers and pants off the rest of the way.

Regulus wasn’t much better, blouse torn and the corset somehow falling apart a bit, skirt ruined and the knickers shredded around his ankle as he flicked them the rest of the way off. 

The only thing possibly salvageable would be the red cloak and the knee high socks. 

Regulus whimpered as Remus’ cock twitched inside him, lashes fluttering as Remus shushed him gently and stroked his stomach. 

“I can feel myself,” Remus murmured, gently tilting Regulus’ head down to see the small bulge in his stomach. Regulus made a soft noise and Remus just stroked his hair lovingly, twisting the dark curls around his fingers. 

“You did so good, darling. You handled Moony so well,” Remus praised, peppering Regulus’ neck and shoulder with kisses, mindful of the bitemark he left. “So beautiful,” Remus murmured, tilting Regulus’ head back slightly to give him a gentle kiss to the red, glossy, bitten lips, only to pull away and admire the glassy look in Regulus’ eyes— the lashes clumped together by tears, and flushed cheeks that made his soft freckles stand out against the skin.  

Absolute ruin.

Remus could feel Moony retreat slightly in his mind, less volatile now than previous moons. 

Regulus was nearly nonverbal, finally catching his breath as he began to come back down a bit, sinking back into Remus’ chest. 

“I love you,” Regulus finally managed, eyes threatening to shut as exhaustion began to take over. 

Remus pressed a tender kiss to the side of Regulus’ head. “I love you too, love. Rest now, I’ll wake you when my knot goes down so we can get you cleaned up and properly taken care of,” Remus said softly, his demeanor gentle as he gently stroked Regulus’ side. 

“Truffles?” Regulus perked up slightly through the fog that threatened to overtake him. 

“You’ve definitely earned truffles,” Remus chuckled, chest vibrating against Regulus’ back. 

“I’m going to need a new costume,” Regulus mumbled sleepily, beginning to drift off, “Don’t think I could wear this one again without getting hard… torn or not.”

“We’ll worry about that later, pretty boy,” Remus said softly, slightly amused as he continued his gentle touches. 

Regulus made a content sound, finally closing his eyes fully as he drifted off in Remus’ arms despite the knot inside him. 

He loved the feeling of being so full of Remus. 

But Remus didn’t know Regulus was already scheming for the next full moon, figuring out how to take Remus’ knot again and provoke the wolf further. 

And Remus would gladly let him.
