Fireside: A Sirius Black Christmas Oneshot

Happy holidays, loves! Here is a gift for my Sirius Black friends. Tumblr exclusive for now, probably cross-posted to my AO3 and Wattpad eventually.

A few warnings— it’s EXPLICIT smut. 18+ interaction only, please.

It’s a Sirius x You (fem-reader) fic, but you have a House. It was necessary for the plot. Hopefully you are House-flexible or can be for the next 6k+ words.

Get warm and cozy and enjoy… and please let me know what you think… reblogs are much appreciated, as are likes and comments. I love chatting with readers and fellow Sirius lovers.

You stood at the doorway to Number Twelve with your heart beating wildly against your chest. Harry and the other students had left for second term just a few short hours ago, with the Weasleys close behind. They were giving Arthur the chance to continue his recovery at the Burrow, hoping to speed his efforts with the comforts of home rather than the sullen, dreary darkness of Grimmauld Place. At least that’s what you’d overheard in their whispers after last night’s dinner, which had followed the last meeting of the Order for the year.

The whispers, of course, were for the benefit of the one inhabitant of the house who wasn’t granted the choice of leaving. No matter how dark and dreary, no matter how much his spirits needed lifting. And they certainly seemed to need lifting last night. As soon as the meeting had adjourned, Sirius Black retreated upstairs with nary a goodbye. Harry had seemed disappointed at this. It was only natural he’d want to soak up every minute possible with his godfather before returning to Hogwarts. But Black had fallen prey to another “fit of the sullens,” as Molly liked to label them with a disapproving shake of her head.

You understood those types of fits all too well, having suffered your own tragedies throughout the Wizarding Wars, as well as typical adolescent heartaches and disappointments that seemed to continue into your early adult years too. Maybe you simply took things too seriously. Life just seemed to come easy to more carefree witches and the wizards that worshiped them. You’d heard stories that Sirius Black himself used to fall into that lighthearted, devil-may-care category many years ago. But he’d experienced unimaginable darkness, and you knew the last thing he needed was to hide away alone, even if he fought you tooth and nail over it.

With a sharp intake of breath, you broke through the warded door with charms meant only for official gatherings of the Order. You prayed to the gods that there wasn’t some terrible punishment for doing so. You sighed with relief when you were greeted only by the eerie silence of cold, dark air— which was a sound unto itself, strange as that seemed. The familiar dank smell filled your nostrils, but it didn’t bother you. It simply set the ambience of a home filled with magic and mystery and stories, dreaded though some of them may be. The walls were alive with history, and there was something intriguingly romantic about the place, if you were honest. You knew the man you were about to encounter would adamantly disagree and would probably throw you out on your arse for thinking so. You’d be sure to keep your strange admiration for the place to yourself for a while, at least until he warmed up to you a bit.

That could take awhile indeed, you thought grimly. Rather than start on such a task right away, you chose to descend to the kitchen and make yourself a calming cup of tea. Perhaps a drop or two of schnapps for some liquid courage were in order also. As the kettle warmed, you made your way to the flocked tree in the rear of the kitchen and smiled as you studied the ornaments there. Sirius himself had conjured and crafted most of them just days earlier, when he’d been noticeably more joyful. The anticipation of Christmas had lifted him out of his funk, and he’d been determined to replace his family’s fancy heirloom ornaments with much more colorful, animated, and exciting ones. You enjoyed examining them while you waited for the kettle to whistle. They were a glimpse into his true self— the fun, whimsical side you always heard about in tales from the older Order members.

You’d seen that side a bit in your interactions with him so far. He had a certain glint in his eye as he teased you for your lack of coordination, which coincidentally had landed you in his lap one evening when you’d hooked the toe of your boot unceremoniously under the crossbar of the wooden kitchen bench.

“I- I’m so sorry,” you had stammered, your face painfully hot. He’d caught you with an arm scooped under your back.

“I’m not,” he’d quipped back with a glimmer in his blue gray eyes. And he’d given your thigh a couple quick pats with his large palm, just fatherly enough that you weren’t quite sure if he saw you as a cute, clumsy, overgrown kid— or something a bit sexier, as that glimmer in his eye along with his comment might have suggested.

Subsequent meetings were difficult after that fateful fall. You couldn’t stop your eyes from straying in his direction. In spite of his scraggly, unkept stubble and perhaps accelerated aging from Azkaban, he was undoubtedly a beautiful man. The Black family genetics were famous for a reason. Their symmetry and grace, smooth skin, full and shiny hair, and silky, aristocratic voices were mesmerizing. It was no wonder they drifted toward the Dark Arts; with gifts like that, they could clearly coerce lesser mortals into doing anything.

Sirius was made only more handsome by the tattoos that covered the previews of skin he revealed— a sexy “fuck you” to the house, the Black family line, and anyone who may chide him for daring to be different. You admired the confidence his swaths of ink portrayed, and each passing meeting made you yearn to study them up close. For academic purposes, of course. Continuing education in Ancient Runes. Field work.

“Do you not take sugar in your tea?”

The voice was quite light and innocent, but it startled you so much you spilled said tea straight through the holes of your wool sweater.

“Fuck!” you hissed. “You scared me, Black.”

He smiled and strode behind you, reaching around your front to grasp a kitchen rag that hung from the lower cupboard handle. He spun you around with hands on your upper arms and promptly began absorbing the spill. Of course he could have taken care of it with a mere wand wave. Interesting that he chose the more manual route.

“I scared you?” Sirius mused. “And to think you’re the one breaking and entering and stealing my tea. Which, strangely, you’re sipping black at the moment. Is this because you don’t know where to find the proper accompaniments, or are you simply that odd?”

“Simply that odd, I’m afraid,” you admitted, leaning back against the wooden counter with legs outstretched. “I like it black. Enjoy the flavor.”

This was met with a slightly arched eyebrow, but he recovered quickly and reached around you again to grab his own mug.

“I prefer it quite sweet, and loaded with cream, personally,” Sirius commented, voice still maddeningly silky and light. It tickled over your eardrums like a melody. His tongue snaked out as he tilted the mug to his lips and slurped.

“Don’t you Blacks have to attend some finishing school before you’re sent to Hogwarts?” you teased him. “Don’t they teach you not to slurp there?”

Sirius didn't miss a beat. “You’ll find I’m a bit of a dog, darling. I’m rather noisy and messy with my mouth.”

That rush of heat filled your cheeks again, and you found yourself trembling a little with adrenaline at how quickly things had escalated. Or did they? The conversation was quite innocent, on a service level. Perhaps your building desire for him had you reading things that weren’t there. You decided to change the subject and try to calm your racing blood.

“You seem quite a bit… happier… than the other day,” you offered as he continued to enjoy his tea. “Did you have a nice day today?”

Sirius seemed to snort. “I had a fucking awful day. How could I have anything but in a place like this?”

“I’m sure it’s not so bad, with the right company,” you pointed out nervously, suddenly scared you might piss him off enough that he’d order you to leave.

“I’ve had nothing but company for weeks,” he replied. “It can help, I suppose. But I’m still trapped.”

You weren’t quite sure what to say to this, so you busied yourself with your own mug, roving the kitchen slowly to avoid eye contact while you plotted where to go next.

“Is that why you’re here?” Sirius continued softly. “Do you believe you’re the ‘right company?’” His expression seemed skeptical.

You shrugged shakily. “I— I dunno. I guess I just thought… you shouldn’t be alone. I… I like being alone occasionally. But you… you don’t really seem like that type.”

“Not a bit,” he agreed. “But it’s not just about the company. It’s about experiences. And I’ve experienced everything there is to do here. Millions of miserable times over.”

You bit your lip, knowing you could never be so bold as to suggest novel experiences he might try. You were pretty sure he hadn’t had many of those— if any— within these walls. Not with multitudes of pureblood portraits staring him down. Of course he very well could have fooled around with pureblood girls here growing up, right? Just because he wasn’t a supremacist like his forebears didn’t mean he couldn’t enjoy a dip in the pureblood pool from time to time.

“So,” he continued, addressing you by your name as he crept closer, step by step. “What experiences are you bringing with your company? How will you keep me from being bored?” His eyebrows arched and narrowed adorably with his words as he challenged you.

He stopped just short of invading your space, so you could still view him easily from head to toe. He wore a thick velvet robe in deep burgundy overtop a black and green pinstripe shirt that was honestly a bit… Slytherin-like, when taken in isolation. Perhaps he hadn’t invested in a new wardrobe upon his return and simply relied on the house’s contents. But it suited him nonetheless— this regal contrast of the two houses adorned with his double Albert chain and shiny brown dress shoes. Of course the colors were befitting the season as well, a reminder that Christmas joy still lingered in the air, if one looked for it. You imagined that the house once saw splendid Christmas feasts— glittering, elegant affairs filled with firelight and extravagance as the Wizarding World’s upper crust filled every floor. Personally you enjoyed picturing something more intimate, more cozy, within those old walls.

“Let’s light a fire,” you suggested, setting your teacup down and leading the way to the parlor.

Sirius scoffed behind you but followed nonetheless. “Why would we do that? The entirety of the house is under a warming charm, darling.”

“Hogwarts has fires in the common rooms, does it not? They were nice.”

“Nice, but obviously unnecessary,” he continued practically.

“You need some actual warmth in this place,” you insisted, setting to work lighting the floo. “The kind of warmth that feels good on the inside too. Comfort. A glow.”

“You’re a Hufflepuff, aren’t you?” Sirius asked with a snicker, reclining in a large, faded velvet armchair. He spread his legs in a wide slouch, and you couldn’t help but gaze downward at the movement. Thick, ribbed corduroy slacks hugged thin legs and tapered down to fine silk socks, above which you saw the faintest glimpse of pale skin and dark hair.

“What does my house matter?” you returned in a non-answer. The fire roared to life in the large black marble, and instead of joining him in the companion armchair, you chose to settle on the rug right in front of the flames. Your skin was already on fire, of course, from the turn-on of his earlier proximity and banter. But the added warmth felt nice, and you hugged your knees to your chest.

“Your house doesn’t matter,” he agreed. Just simply a guess. Now, what about that experience you’re going to offer me? Still waiting for an answer on that one.” Sirius rested an elbow on the chair arm, his fingers toying with the ends of his long mustache where it met the unruly stubble on his chin.

“Come down here with me. This is an experience,” you responded, patting the empty space next to you on the rug. It was thick and smooth, richly woven, and of course very expensive. You could feel thick loops of fine threads beneath your fingers as you traced its intricate pattern.

“Sitting by a fire?” Sirius asked incredulously. But he did make a move to join you, settling down in the spot you indicated and then shifting closer. His robe brushed the sleeve of your sweater, and he made no move to back away.

“Well, what kind of experience did you have in mind?” you shot back.

Sirius shrugged innocently, eyes twinkling in the dim light. “No idea, love. You’re the one who showed up on my doorstep, remember? Don’t you have a plan for these things? Or are they spontaneous? Maybe you’re a Gryffindor then?”

You gave a small smile, refusing to answer the question. Instead you studied the details of his face you’d never noticed from afar, features augmented by the dancing shadows of light. He had a very well defined facial muscle that gave an intermittent sexy twitch. And another defined crease on the underneath of his nose that made you curious if you had one; you had always just envisioned it to be smooth. But most magnificent was the way the firelight bounced off of every soft curl — a bountiful dark mahogany crown that would be the envy of any woman alive. You longed to run your hands through it, betting it was even more luxurious than the tapestry rug beneath your increasingly aroused bottom half.

“I’m beginning to feel rather exposed,” Sirius declared, amused. “I don’t think I’ve ever been examined in such detail before. Is this for ‘science,’ as the Muggles say?”

You cleared your throat nervously. “Uh, yes. Wizarding genetics, I guess. You’re just very… impressive.” You winced at the terrible recovery.

Sirius responded with a sweep of a tattooed hand over your cheek. “I’m flattered, coming from a witch as exquisite as yourself. Not to mention young. I believe I have quite a few years on you, yes?”

Your heartbeat was painfully audible as you tried to craft an answer. His fingers still explored your face, alternating with occasional twists of an adjacent lock of your hair. Each sweep of his skin over yours seemed to make your veins tremble.

You truly didn’t know how to respond. Your Muggle friend had once informed you that the term for your specific brand of fixation was “daddy kink,” but you weren’t sure admitting that would do you any favors. You liked how his touch was so self-assured, and the richness of his scent, and how he always knew what to say without hesitation. You liked how the hard lines of his face and hands denoted strength and experience. And you liked how he made you feel small and fragile and protected just by being near you. You wished you could tell him all that without sounding ridiculous. But you were fairly certain you were already communicating it with your parted lips, panting breath, and love-drunk eyes.

“You are going to make my night interesting after all, aren’t you, little one?” Sirius husked, and the bud between your legs danced frantically up and down in response. How did he know to call you that? Your eyes closed with the dizziness of your anticipation, and the hand that had drifted so gently over your cheek now rested fully on your throat. His scent became even more pronounced, alerting you to his closeness just before his mustache tickled your upper lip in the briefest of warnings.

The kiss he gave you was chaste and just enough for you to learn the shape of his lips before he pulled away.

“If you don’t want this, you need to tell me,” Sirius said, his voice low as it drifted directly across your ear. “I’ll stop if you ask me to— at any point. But this is the only asking I’ll be doing myself. Once I begin, you’ll find I’m far too busy to stop and check in.”

His forehead rested gently on yours, his deep blue eyes smoky in the dim light.

“Busy doing what?” you whispered— half teasingly, half desperate for the fire between your legs to be stoked by all the dirty things he would promise.

Sirius chuckled lowly. “You like dirty talk, little one?”

Your affirmative answer came as a whimper, which elicited another devilish chuckle from his lips.

“Very well,” he said silkily. He punctuated the words with another firm kiss on your lips, this time allowing the very tip of his tongue to trace the outline of the bottom one before planting light kisses along your jawline to your earlobe. He paused there, allowing a breath to tickle your ear before he spoke.

“I am going to make every part of your body come alive, as if I cast a spell. But there will be no wand— only my hands, my mouth, my voice. I will make your delicious cunt so wet it will be weeping for my cock. Then I will bury it in you so deep you scream… so loud you’ll wake every portrait in this house and make them curse your sweet, beautiful name. You will ride my cock for as many mind-numbing orgasms as your body can handle, then I will take my pleasure and fill you so full of my seed that it trickles down these soft, smooth thighs all day long tomorrow. You’ll feel it and remember me, and you’ll want it all over again.”

Sirius accompanied his filthy murmurings with firm strokes to your inner thigh, hand already buried inside your skirt. You let out an almost agonized groan in response— all intelligible communication now impossible. Your body literally shook just from his promises, and you knew the look you gave him as he came to a kneel on the rug was one of complete and utter submission.

His hands came beneath your head to cradle it, hands swept in the tangle of your hair as kisses became more insistent, open-mouthed, and allowed you taste the salt and firewhisky on his breath. His tongue explored in gentle licks followed by long sweeps of your mouth, as if it was truly a mission to discover inner parts of you and not just kissing.

You became eager for his hands to move elsewhere, but they still held your head still for his mouth to continue its wicked work. His kisses made your head spin, but the rest of your body felt in heat and neglected. You came to your knees yourself, hands introducing themselves to the sturdy velvet of his jacket, your legs making a move to straddle one of his trousered thighs. He let out a low laugh.

“So eager,” he chastised. “I’m the one who hasn’t shagged in fourteen years, yet I’m the one demonstrating all the patience.”

“I want you!” you defended yourself breathlessly, not even caring if you sounded desperate now. You just needed relief, and to have this wizard covering every inch of you.

“Ah, there it is. The answer I needed to my question,” he said with a wink. “You needed to give me permission, you know.”

“You have it,” you insisted, and as a visual aid to your words, you took the initiative to shrug out of your own sweater. Your breasts swelled over the cups of your lacy, favorite-colored bra. You noticed Sirius became strangely still at the sight, his mouth parting.

“Fucking beautiful,” he managed to mutter, and he cast his own robe aside to free his movement as he reclined you both onto the rug. His fingers gently slid one strap from your shoulder, replacing it with his mouth and soft whiskers. The detailed attention he paid to a spot as random as your shoulder reminded you of his promise to awaken every part of your body. Sirius planned to make every cell literally beg.

His kisses danced across your collarbone in a similar fashion, tended to the next shoulder, then came to center on your pulse point, where he began a gentle suction. You let out a cry at this and took the chance to enjoy his gorgeous, thick curls while he worked his mouth on your upper body’s most sensitive spot.

“I’m going to have wicked marks if you keep doing that,” you teased with a whisper. Sirius’s nose brushed your earlobe as he went for the other side, sucking the sensitive skin beneath like he was starving.

“Good,” he finally broke to whisper back. “And your neck’s not the only spot I plan to mark you.” He added teeth to the mix now, grazing lightly over your throbbing pulse. Would he bite? Would you even care if he did? But he only threatened such before moving lower, working your arms out of the dangling bra straps to reveal your breasts to him. His breath caught in his chest as he appreciated them with his eyes first before cupping them hard, one in each hand. His rough thumbs drove your nipples into peaks, watching each little bump emerge with fascination.

You observed him with a smile, arms leaned back behind you to prop you up for his amusement. You realized of course that it had been over a decade since he’d played with such toys, and though your body was humming for more, you granted him his boy-like fun. Sirius alternated between circling your nipples into painfully hard peaks and kneading your breasts like dough before finally suckling the left into his mouth. The action caused your eyes to roll back in your head. This wizard knew what he was doing. It was more than just taking the soft, pliable tissue into his mouth— he created a firm, merciless suction whose movements echoed between your thighs in violent waves. Your legs parted reflexively, and you grabbed his hand, encouraging it down to feel your burning heat.

“Please touch me,” you begged. “I’m so wet for you.”

Sirius responded to this with a hungry growl, releasing your breast to reveal brand new marks as promised. He gave the other another very rough squeeze before grabbing at your skirt, ripping it downward. He sent it hurling away, narrowly missing the fire. The rip of lace echoed through the air as your knickers followed.

“Am I supposed to walk home with no knickers tomorrow?” you mused above the noisy kisses he planted to the soft skin of your stomach.

“You’re not going home tomorrow,” he replied quickly. “And you’ll be naked all day. And you certainly won’t be walking by the time I’m finished with you.”

“Oh, so you— you like it rough then?” you asked between gasps, shuddering as his fingers traced the tops of your inner thighs, which opened to the hot breaths drifting over your sex.

“Not always,” he answered, grinning up at you from between your parted legs. “But the Black family genetics extend to other endowments as well. In both size and stamina. Even sweeter lovemaking can lend itself to the need for pain potions, love. Do you still consent?”

You licked your lips and lowered your eyes, feeling them burn with sultry want. “I thought you weren’t going to ask anymore?”

“Gryffindor chivalry,” he dismissed with an adorable pursing of his lips. “It’s a curse sometimes.”

“Yes, I consent,” you answered with a grin of your own. “But before you touch me like I asked, I want you out of those clothes. I need to see this endowment of which you speak.”

Sirius sat up and gave your thighs a swift tap before closing them. Your own wetness was dripping onto them at this point, and you could smell sex on the air already.

“You don’t believe me?” he inquired with raised brows.

“Well, you know, Gryffindors are fond of bragging…”

Sirius let out a deep laugh. “So I can assume you’re not a Gryffindor, then, with a comment like that.” He stood and began disrobing, his thumbs drifting over the buttons of the dark green shirt. Each tattoo he revealed made you salivate. He wore a thick, shiny belt buckle now displayed over a prominent bulge in his trousers, and you imagined he was growing quite uncomfortable in there.

“Still not telling you my house,” you replied, shifting your closed legs from one side to the other as you watched your strip show, offering him tantalizing glimpses of your cunt and arse but never separating your thighs for a full view. Sirius never took his eyes off of you, and when his trousers swiftly lowered, you were greeted by the surprise of no underwear— followed by the thick, glorious inches of a very hard, uncut, pureblood cock on display. Your jaw dropped open.

“Already opening up for me?” Sirius commented silkily. “Good girl.”

You nodded, ready to have your mouth fucked speechless if that’s what he wanted. But Sirius seemed to have other plans, pouncing back on you in under a second. He parted your legs almost violently, his face voracious as he plunged his nose into your soaking wetness to inhale before licking furiously.

“Oh, fucking gods!” you moaned, arching into his frenzied movements. He was truly very noisy and beast-like with his mouth, as he’d warned. His tongue alternated between flat, all-encompassing licks across your entire slit, and tiny, strong, targeted flicks around your bud. He approached your sensitive, nerve-filled opening with his tongue in a stiff point, swirling it around to beckon wetness from you in droves.

“I’m fucking drowning you down there,” you moaned, arching your back against the soft rug.

“I told you I like loads of sweet cream,” Sirius responded with a murmur. “Keep it coming, love. Soak my face.”

His tongue rammed your g-spot now, his whole stubbled face buried in your cunt. Your smell filled the hot air and was so sexy you wanted some yourself. Sirius seemed in tune with your needs because his fingers found your hole as his tongue drifted upward to concentrate on your swollen bud again.

“Let me taste your fingers,” you whispered.

“So you do like sugar and cream after all?” he chuckled before obliging with a rather rough shove of his soaked digits into your mouth. His wet stubble scratched your face as his words sought your ear. “Or maybe you’re just a very dirty girl.”

You sucked the delicious sweet-salty combo from Sirius’s fingers, offering kitten licks, strong suction, and previews of all the things he could expect once that glorious cock was in your mouth. His hand found its place within your slit again and began purposeful movements, the back of his palm massaging your clit as his fingers found the g-spot again, kneading the spongy, swollen tissue.

“Please fuck me,” you begged. “I need your cock.”

“Oh yeah?” he mused delicately, leveling his heady eyes to yours. “You don’t like what my fingers are doing to you, darling?”

“I love it,” you panted. “But I’m gonna come!”

“Then come, sweetheart. You can still come on my cock. Promise.” Sirius’s hand picked up its pace so any resistance was hopeless. His mouth returned to your neck to secure you in place as the waves took over your body, your whole frame convulsing in one giant shake after another with your beautiful release against his hand. Sirius’s wet mouth closed over yours, his tongue invading as he situated his warm, taut body between your legs. Your bud was still tingling with aftershocks when he touched the head of his cock to it, angling for pressure.

His girthy shaft sought its spot between your glistening lower lips, hips driving the thick tip up against the underside of your clit, and his hard, veiny surface sliding against your still swollen vulva. Sirius wasn’t going to let the pressure ease for even a minute, making sure to build another climax even stronger than the first for his cock to work you through.

“Inside me, please!” you breathed into his mouth.

“I think you can come just like this, darling,” he argued. “Don’t you?” The ridge of his cockhead massaged your clit furiously with his back and forth, and your body gushed messily all over his shaft. Your nails made deep half moons in his tattooed shoulders.

“Y— yes, I can come for you.” You arched up to grind into his impossibly hard length, seeking the rhythm and friction you needed to push over the edge. It required wild gyration and complete abandonment of any self consciousness. Your breasts bounced against his chest, and you clung so tightly to him to ground yourself that your nose was buried in his curls, smelling his animalic musk.

You screamed as you reached peak again, the tremors tinier this time but still exquisite. Exhausted, you fell limply to the rug and took him with you, giving grateful caresses to the smooth skin of his back. Of course you were still aware of his inches throbbing against your thigh, and you knew you had to summon more energy if you were going to give Sirius the satisfaction he needed. The man hadn’t lain with a woman in nearly a decade and a half, and you wanted his cock thoroughly and ecstatically drained. You’d be lying, though, if your twice-satisfied cunt wasn’t worried about such a massive invasion. Your gratitude for the blissful, explosive orgasms aside— you kind of wish he’d honored your request and fucked you when you were swollen, open, and on fire.

Sirius raised himself on his elbows, gazing down at you with a lazy smile.

“You’re really fucking beautiful, you know that, Slytherin girl?”

You blinked and jumped. “What?”

Sirius gnawed at his lip and continued to grin, deep blue eyes sparkling. “You heard me.”

“What makes you say that?” you demanded. “You haven’t even guessed Ravenclaw yet!”

“You let me fuck you way too dumb to be a ‘Claw, and I haven’t even fucked you yet,” he pointed out. “I’ve had my fair share of Ravenclaw witches, and they never quite know when to shut up, Merlin love them.”

“Hey, Slytherins are smart too,” you said with a narrowed brow before you could stop yourself.

Sirius gave a hard smack to your arse before pulling you onto your side, his erection buried in your stomach. You laid breasts to chest, feet and legs entangled, faces flush.

“Tell me,” he said with a slight scowl. “How did they let another Slytherin into the Order? Do they not have standards anymore?”

“Oh, fuck you, Black,” you muttered.

“You’re still doing that, darling, don’t worry. No slithering your way out of that one. You know I’m just trying to rile you up and get you going again so you can handle my cock. Maybe a hate-fuck would be a nice game, now that our alliances are on the table? Would you like that?” His fingers tickled down your ribs and hips before finding the triangle he sought, just his fingertips easing lower to scissor your bud.

“Our ‘alliances’ are the same, you prick,” you laughed, accepting his fingers with an approving arch of your hips.

“Yes, but this new tidbit makes it so much more fun,” he insisted. “You’ve delivered on that new experience I wanted. A fine Christmas present indeed.”

“So this is your first time with a Slytherin?” you asked, doing nothing to hide your pride at that possibility.

“Virgin,” Sirius confirmed with a nod. “As if twelve years in Azkaban didn’t revirginize me enough, this makes it official. Now, show me what I’ve been missing.” He collapsed rather dramatically on the rug, hand behind his head, curls strewn about the intricate paisley pattern. His body was breathtaking— glowing in the firelight, each turn of muscle accentuated by shadow, each tattoo taking turns in the spotlight with the maneuver of flames. And at the center of the beauty was that cock, which hadn’t lost a bit of wind with this latest reveal of information. A generous leak of precum glistened at the tip, and you lowered your mouth to drink it in, your hair tickling his thighs. The first taste left you craving more, and your mouth slid over his huge shaft like a sleeve, locking him in your throat. You heard a grunt of shock escape his mouth.

“Fuck, that was fast,” Sirius groaned.

You eased off of him teasingly, lips forming an up and down suction which you accompanied with twists of your hand. He tasted positively feral yet clean and refined, just as you would have imagined. His tip leaked loads into your mouth, feeling like it would burst at any second if it weren’t for his exceptional control.

“Mmm… you taste good, Black,” you moaned approvingly. “Almost good enough that I’d settle for your load in my mouth if I didn’t want you to fuck my pussy so badly.”

“On your knees, fucking snake cunt,” he ordered with a wink, the fact that it was a game unmistakable. You gave one long, final suck up his shaft and gave a squeeze to his balls, drawing another deep groan from him.

In an instant Sirius’s hands were in your hips, holding you in place while his dripping head found your center. He was right— the banter had you on fire again, and your swollen walls took every inch of him as he pushed inside without hesitation.

“Ahhhh!” you cried out, unable to help yourself. His hips were a frenzy, abandoning every bit of his previous control now that he was within your tightness. Your breasts bounced in mad circles with the force of his pounding, and sure enough, you could hear the portraits stirring down the hall from the primal noises the two of you made.

“Oh, Sirius, yes,” you breathed, enjoying the repeated raking of his tip, ridge, and underside along your spongy, swollen front wall. He knew just how much to drag back and surge forward, never breaking the rhythm you needed to build to another crest in a matter of minutes. His chest was sweaty when it made contact with your back, and he occasionally dropped open-mouthed kisses to the skin of your shoulder blades with his forward surges. Every so often he broke his rigid support on the rug to squeeze your breasts, kneading them so tightly you knew you’d have bruises for weeks.

“Feel good, love?” he husked, and you knew he knew full well you were beyond good. His ego just wanted to hear it.

“Yes, Sirius. Fuck yes. Please come inside me.”

And it was truly your foremost want in that moment — to fill his hot cum paint your insides and have the satisfaction of giving him what he’d needed for so long. He renewed his lock tight grip on your hips and granted your request, resuming the pounding of your g-spot but faster now, the friction very much for his benefit— with yours as a mere pleasant side effect.

“Fuck, yes, I’m gonna fill you so full,” he promised breathily. “And you better come for me again. You better scream.”

You reached around to toy with your clit and make sure you obeyed his command, but he swatted your hand away and replaced it with his own, his fingers taking on a rhythm to match his snapping hips. All you could do was let out a long stream of moans and buck furiously in return, knowing that chasing your own pleasure would only increase his. His escalated moans confirmed he was approaching release, and you grinned as you picked up the pace even more feverishly, wanting to torture it out of him.

“Fucking GODS!!!” Sirius yelled, and he emptied into you with one hot jet after another, so much it ran right back out over his trembling cock. You kept your pace even after his cock stilled, the added lubricant from his release making easy work of your movements. The thought of being filled with him made your orgasm deliciously hot and dirty as your walls burned with pain and need. Sirius recovered enough to resume the pace of his fingers on your clit, and you spilled over the edge, lurching forward in a series of shakes that wracked your entire body.

You fell forward onto your belly, a mess dripping from your insides, your muscles and bones useless, your skin bruised. It was every way you should feel after a proper fuck. Your brain positively hummed with endorphins, and you breathed in the deliciousness of your combined sex on the air. You could hear Sirius struggling to regain his breath behind you, and you knew he looked sexy as fuck back there. But you were too exhausted to lift yourself up and look.

You weren’t even sure how much time had passed when you felt his arms encircle you, along with the cold rush of air as he lifted you from the warmth of the rug. He wasn’t a huge man, though you’d heard from other Order members that he was considerably stronger now than when he’d escaped the sea prison two years ago. He carried you easily up multiple twists of stairs until you reached a Gryffindor red room on the very top level. Then Sirius nestled you gingerly into a brightly colored duvet.

“Will you be able to sleep with this much red, or should I move you to the green room next door?” he asked dryly, shuffling his naked body next to yours and leaving you little choice in the matter.

“Well, it is Christmastime,” you reminded him sleepily. “The two play rather nicely together right now.”

Sirius responded by nuzzling into your shoulder, his whiskers scratching tiny red prickles into your skin.
