When Sirius had first asked him to move in with him after school Remus was initially reluctant. 

He had brushed him off more than once over the course of their seventh year, having a sinking feeling in his gut that despite his high N.E.W.T. scores the odds of him finding and keeping a decent job were slim to none, and not only did he not have more than a handful of coins to his name but he really didn’t want to ask his parents for money, so with a bitter sense of resolve he’d packed up his trunk and moved back into his childhood bedroom once school had finally finished.

Which didn’t quite go the way he wanted it to.

Living with his parents was stressful and difficult, butting heads with his tad constantly and tearing his hair out over the total lack of privacy despite the fact that he was now a grown man, making the commute to London on a near daily basis to look for employment and see his friends, watching as they made strides to become functioning adults all while he slept in a twin size bed with little circus animals on the sheets. 

Every single time that he met up with Sirius he would ask him to move into his Camden flat with him, the one that Remus had absolutely no way of paying his share for, bringing it up again and again at every available opportunity. After a year of dealing with his parents overwhelming-yet-loving hovering Remus had finally reached his breaking point, which led to him suggesting a little arrangement.

“Moony,” Sirius says from the sofa, and Remus finishes writing the passage that he’s transcribing for a freelance job that he picked up off an owl board before he sets his quill aside and looks over at him. Remus sucks in a little gasp when he sees that he has his joggers pushed down around his thighs, one hand wrapped around his cock as he slowly strokes it, already fully hard and flushed red at the head. “I want you.”

“Yeah, of course,” he says, rising from the table tucked into the corner of their small kitchen at once, taking off his reading glasses and leaving them on the sideboard as he crosses the room. “How do you want me?”

Sirius hums beneath his breath, tilting his head to the side in consideration before he nods, kicking his joggers all the way off. “I want your arse.”

“Okay,” Remus says, licking his lips as he quickly strips out of his clothing, leaving them in a neat little pile next to Sirius’ joggers. “Do you want me to ride you?”

“Yeah, for now,” Sirius says with a shrug, giving his thigh a pat as if offering him a seat. “I want to keep watching my show, but I might rearrange you later depending on how long this takes.”

He nods, putting his knee on the cushion on one side of Sirius’ lap and swinging the other over so that he’s straddling him, reaching behind himself and hooking his fingers around the base of the silicone plug he wears to keep himself stretched and ready. He makes a little noise in the back of his throat as he pulls it free, lube and come dripping out of him as he sets it on the table next to the sofa. He reaches down and grips the base of Sirius’ cock, muttering a lubrication charm and slicking him up before sinking down on it in one smooth move, moaning a little at the stretch and burn despite the fact that he’s already been fucked once today. 

“Alright?” Sirius asks, hands sliding up his thighs and coming to rest on his hips, giving him a little squeeze as his eyes move from the television screen to his face.

“Yeah, fine,” Remus responds, giving him a small smile before he adjusts himself more comfortably, resting his forehead against Sirius’ shoulder as he starts rolling his hips, starting out slow because he’s well aware that this is a marathon and not a race. 

The thing about Sirius is that he has a ridiculously high libido. 

The man always wants to get off, spending most of his days walking around in a constant state of arousal, and it’s a perfectly normal occurrence to walk into the kitchen to find him making dinner with the front of his joggers tented out obscenely in front of him from his hard-on, or to catch him wanking while doing something perfectly average like watching telly or reading a book. Remus is used to it by this point, he did share a dorm room with him for seven years after all, and due to the nature of their arrangement he’s more than happy to lend a helping hand, mouth, or hole whenever needed.

The other thing about Sirius is that it takes him forever to come. 

It’s part of what led to their arrangement in the first place, Sirius had once confided in him towards the end of seventh year that he’d wanked himself raw trying to get off and still hadn’t managed to come, as well as being unable to find a bed partner due to his frankly absurd stamina. That conversation kept playing on a loop in his mind over the next year, through watching Sirius have a string of unsatisfying hookups while constantly requesting that they become flatmates, and when he’d finally given in to saying yes he had offered him a proposition. 

Remus would move in with him, and in lieu of rent payments his body was free to use at any time, in any way that Sirius wanted, with a one week trial run to make sure that they were sexually compatible. 

It turns out that they are. 

They’ve been living together for three months now and some days Remus spends more time with a cock in his throat or up his arse than he does anything else. Sirius is insatiable, sometimes fucking him for so long that he passes out from exhaustion, still hammering away at him when he eventually wakes up again, the evidence of his unconscious orgasms spread across his chest. Other times he simply wants to be inside of him, having Remus kneel between his legs or perched on top of his lap, alternating between fucking into him and simply letting him keep his cock warm, playing with his hair or stroking his back as he does. Occasionally Sirius wants to bottom, which is considerably more work, and Remus will spend what feels like the entire day switching between fucking him and fingering him, his hand or his mouth wrapped around his cock as he does, swapping between the two whenever his fingers and jaw start to cramp. 

Remus loves it all regardless. 

When he’d suggested the arrangement it was simply a means to an end, a way to get out from beneath his parents roof and getting to move in with one of his best friends instead, but he didn’t know how much he would love it when Sirius would ask to use his body to get off with no explanation or preamble. He loves being used, and he thinks that he might love Sirius too, though they’ve never discussed how feelings might play into this dynamic that they’ve formed and he sincerely doubts that Sirius returns them, so he keeps that little thought tucked away in the back of his head and prays that Sirius never finds a partner that will put an end to the entire thing. 

“Fuck, just like that Moons,” Sirius groans, gripping his hips and pulling him down onto his cock, tipping his head back against the sofa with his eyes focused on the telly, and Remus hums in acknowledgement as he moves the way Sirius wants him to, rising and falling with each roll of his hips. “How much more work do you have to do today?”

“Not much,” he answers, sounding far more affected than the other man, his voice coming out high and breathy. “It’s not due until Monday and I’m nearly done with the entire project.”

“Good,” Sirius hums, one of his hands sliding down between Remus’ cheeks, feeling where he’s stretched open around him before he smoothes his palm up the length of his spine, curling it loosely around the back of his neck. “You work too hard.”

Remus snorts quietly, he’s had this job for less than a month and he was unemployed for nine weeks before that, by no means is he working too hard, mouthing idly at the skin of Sirius’ shoulder as he keeps riding him. Sirius thankfully takes over when his thighs start to ache and his stomach muscles are quivering, gripping his hips and lifting him slightly before he starts thrusting up into him. 

Remus doesn’t even bother warning him before he comes, just like he’s used to Sirius’ sexual proclivities he is well aware by this point that he’s a bit of a hair trigger sometimes, and can come completely untouched, something that Sirius takes advantage of quite often. He moans quietly and whines as each and every thrust drags over his prostate, his cock kicking between his legs before he starts to spill all over Sirius’ bare chest and stomach in long spurts. Sirius hums beneath his breath but doesn’t stop, gripping Remus tightly when he starts to squirm, thrusting up into him and fucking him through the overstimulation until it starts to feel good again, his cock never going fully soft. 

“Let’s rearrange,” Sirius murmurs an indeterminate amount of time later, pulling him down onto his lap and grinding up into him for a moment before he stills and taps his side. “Your hips are probably getting sore, yeah?”

“Mhm,” Remus mumbles, sliding sideways off his lap and collapsing onto the cushions, his legs remaining draped over Sirius’ lap until he gives his arse a playful slap and stands, watching as he starts shoving at the end of the sofa until the arm is facing the television. “How should I-”

“Whichever way is comfortable for you,” Sirius says, casting another lubrication charm and stroking himself as he peers down at him. “I just want to be able to see the screen.”

Remus hums and thinks about it, stretching out the cramp in his left leg before he rolls over onto his stomach, pulling one of the cushions from the back of his sofa beneath his hips so that he’s draped over it, his chest pressed to the sofa with his arms stretched out in front of him and his arse propped up in the air. “Is this alright?”

“Yeah, perfect.” Sirius climbs up behind him and slides all the way into him with a low groan, bending over him to press a kiss between his shoulder blades before he starts to thrust, hands digging into the soft flesh of his hips as he sets a fast pace. “You’re so perfect for me, Moons.”

He moans quietly, feeling his cheeks flush pink before he presses his face into the sofa, closing his eyes as he lets the waves of pleasure roll through him, each slap of Sirius’ hips against his arse making his sensitive cock grind against the cushion beneath him. He tries to keep himself relatively quiet, he doesn’t want to interrupt Sirius’ show, but he always seems rather appreciative of the noises he makes. 

Sirius groans when a little ungh starts falling from Remus’ lips with every thrust, hands tightening around his hips as his thumbs sweep over his lower back. Sirius hikes him up a little, hammering into him and reaching beneath his body to wrap a hand around his cock, grunting happily when he tightens down around him and spills all over the sofa cushion with a trembling whine. 

Sirius slows, but does not stop, as he comes down from his orgasm, letting him melt over the cushion again as he rubs his come covered hand over his lower back. He traces patterns on his skin as he just keeps fucking him, leaving him stick and covered in his own spend, making an offhand comment about the show that he’s watching. Remus makes a little noise of acknowledgment, his body heavy and his limbs tingling as he lets himself be used, folding his arms beneath his head to cushion it as his body rocks gently from the force of Sirius’ thrusts. 

He dozes through his next orgasm, it’s going to happen whether he’s an active participant in the moment or not, the sound of the telly and their bodies slapping together washing over him distantly as Sirius slowly starts to get louder, his pace picking up as he begins groaning and cursing beneath his breath. Remus slits his eyes open to glance over his shoulder at him, finding him with his head thrown back and a flush spreading down his chest as he fucks into him with abandon, Sirius biting out a curse before his hips stutter and warm wetness starts spreading inside him. 

Sirius slows and then stills, staying inside of him for a few moments while he catches his breath, and Remus winces slightly when he finally pulls out of him, arse aching. Sirius shushes him quietly, petting the outside of his thigh as he leans back to grab the plug, working it into him and pressing down on the base of it to watch him twitch before he conjures a damp cloth to clean him up with. He gently wipes between his arsecheeks and his thighs, dragging it over the expanse of his back before he lifts him and cradles him in his lap, distractedly casting a cleaning charm at the soiled cushion before he cleans his softening cock. 

“Alright?” Sirius asks, tossing the cloth to the side before he brushes his lips over his forehead, wrapping his arms around him and hugging him to his chest. 

“Mhm, I’m good,” Remus answers tiredly, tilting his chin up when Sirius noses at the side of his face and sighing as he presses their mouths together, melting into the kiss as Sirius runs a soothing hand up and down his side. Sirius rarely kisses him before or during the sex, but he always kisses him afterwards, and he almost enjoys the aimless snogging and soft cuddles as much as he does getting railed within an inch of his life. 

“Here,” Sirius says after a little while, pulling away from his lips and holding up a glass of water that Remus didn’t even notice him summoning in front of his face, keeping one hand on the glass to hold it steady as he drinks. Sirius murmurs beneath his breath, the burning soreness fading from his arse as the healing charm takes effect, a cleaning charm erasing the lingering sticky feeling from his skin only seconds later. “How are you feeling, Moony baby?”

“Tired,” he answers honestly, smiling weakly as Sirius chuckles and leans down to kiss him again, his tongue dipping into his mouth before he pulls away. 

“Take a little nap, Moons, you probably need it.” Sirius grabs the throw blanket from the back of the sofa and pulls it around him, tucking Remus in tightly before he guides his head down to rest on his shoulder, kissing the top of his head as he cradles him in his arms. “I’m going to order takeaway so that we can eat when you wake up. Chinese alright?”

“Mhm, perfect,” he hums, snuggling down against Sirius’ chest and letting himself begin to doze again. “Remind me to finish my work after dinner.”

Sirius just huffs and kisses the top of his head again, holding him tightly as he falls asleep. 

Remus has decided, stupidly, that he’s going to try to make bread. The stuff that he buys from the shops just isn’t the same as the kind he grew up eating from the little bakery in his village, and while he might have more money now than he’s used to having he isn’t quite ready to start shelling out the coin to buy nicer bread. 

He’s been carefully tending the jar of sourdough starter on the counter over the last ten days, discarding half of it and stirring more flour into it each morning, and according to the recipe book he brought home from the charity shop it should finally be ready to use. 

He followed the instructions in the book carefully, combining the starter with the rest of the ingredients before leaving it to rise, and he’s just gotten to the point where he’s dumping the gloopy mess out onto the floured counter top to be kneaded when Sirius wanders into the room with his hair still dripping from his shower and a towel tied around his waist. 

“What are you up to, Moonbeam?” he asks, opening the fridge and peering inside it before he grabs the orange juice, drinking straight out of the carton.

“I’m making bread,” Remus answers confidently, even if his dough doesn’t quite match the ones in the picture, dusting his hands in the flour before he starts trying to knead it. 

“Huh.” The fridge door slams before Sirius steps up behind him, hands landing on his hips as his chin hooks over his shoulder. “Well, it smells good.”

“Yeah that’s the-” 

Remus’ throat goes dry and his knees weak as Sirius hooks his thumbs into the waistband of his pajama pants and pulls them down below his arse, fingers slipping between his cheeks and pressing down on the base of the plug before he starts twisting it out of him. Remus moans quietly and spreads his legs a little, shivering when the plug finally pops free, the rubber hitting the floor at the same time as the towel before Sirius is pushing into him in one long, burning thrust, lube dripping out of him and sliding down the backs of his thighs.  

“Well?” Sirius asks, drawing his hips back and snapping them forward again, and Remus nearly falls until he braces his hands against the counter, arching his back slightly as he thrusts into him with short, fast strokes. “What makes it smell so good, Professor Moony?”

“It’s, ah, it’s the fermentation process.”

“Hm.” Sirius grabs his hips and jerks him backwards a little, one hand sliding up his chest to hold him steady as he fucks him, their skin slapping together loudly. “Go on, then. Make your bread.”

Remus takes a deep breath and slowly lets go of the counter, trying to maintain his balance as he’s repeatedly shoved forwards, and digs his hands into the goopy mess as he starts to knead it. It’s impossibly difficult, his entire body being jostled with each roll of Sirius’ hips, glancing over at the book to check the instructions and moaning loudly when Sirius gives him a particularly hard thrust.

Remus ends up on his knees with his cheek against the kitchen floor, wailing as Sirius fucks into him like a man possessed, dried dough flaking off his hands as he scrabbles uselessly at the tiles, his come splattering against his stomach as Sirius fucks him through yet another orgasm.

The bread turns out like shit. 

Afterwards Sirius cuddles him on the couch for hours, gently running his hands through his hair and down the length of his back, reading out loud to him as he dozes on his chest before he slides into him once again. The next morning Remus finds a box from the fancy bakery down the street waiting on the counter for him after Sirius has fucked him and left for work, filled with two loaves of sourdough bread and an assortment of pastries. 

Remus is down on his hands and knees, sweeping the dust bunnies out from beneath the sofa with the little brush and dustpan his mam sent home with him the last time he visited, when he hears the floo crackle to life behind him before there’s a deeply appreciative groan. 

“I don’t know what you’re up to, Moons, but I am loving the view right now.”

Remus smirks and gives his arse a little wiggle before he sits back on his heels, when he’d decided that he was going to spend his day off cleaning the flat he’d thrown on his tiniest pair of shorts- the ones he’s had since before he started Hogwarts and has more than outgrown since then- and one of Sirius’ t-shirts, looking over his shoulder at the man in question whose head is hovering within the green flames of their fireplace. 

“Cleaning,” he says, giving the brush a little wave before he sets it aside, frowning at the tension around Sirius’ eyes and jawline. “Is everything alright?”

“Not really,” Sirius sighs, closing his eyes as he stretches out his neck. “We just wrapped up that potions trafficking case that I’ve been telling you about and I’m essentially chained to my desk until I slog through the mountain of paperwork that it has produced, but I’m so fucking horny that I can barely think straight.”

“Oh,” Remus breathes out, sitting up straight as he presses the heel of his hand against his suddenly straining cock. “Do you- Do you want me to come to your office?”

“Would you mind? I know that you’re not a fan of coming here,” Sirius says with a grimace, which is a bit of an understatement truth be told, the idea of walking into the auror department as an unregistered werewolf just seems like an invitation for trouble.Remus doesn’t want to refuse him nearly as much as he doesn’t want to go there, wondering what he should do when Sirius’ gaze flashes down to where his shorts are riding up the crack of his arse, his jaw tensing and his eyes filling with enough heat that it steals Remus’ breath and leaves him dizzy.

“Y-yeah,” he stammers, heart racing as he clambers to his feet, tugging at the hem of Sirius’ oversized t-shirt to make sure that it hides his erection. “Can I come right through or should I put on proper trousers?”

“I will be incredibly upset with you if you change,” Sirius says, giving him a grin and a wink even as his sheer gratefulness seeps into his tone. “Thank you, Moons, I can’t tell you how much I appreciate this. You can floo directly into my office, the password is moonbeam.” 

Remus blinks in surprise as his head vanishes from the fireplace, the flames petering out within seconds, taking a moment to wonder why Sirius would choose one of his nicknames for his floo password. He shakes his head as he summons his wand and takes a pinch of powder from the jar on the mantle, calling out Sirius’ address and the password before he steps barefoot into the green flames. 

Sirius’ office is just as messy as he remembers it being from the one and only time that he’s been here, random auror gear piled in the corners and paperwork stacked on every flat surface, the small sofa in the corner covered in crimson robes and a few jumpers that he recognizes as his own. 

Sirius looks up from his desk and gives him a soft smile when their eyes meet. “Hey, Moons.”

“Hey, Pads,” he says, glancing over at the door as he brushes ash off of his legs, thankfully closed and locked, before he gingerly picks his way through the room and rounds the corner of Sirius’ desk, smiling as he turns his chair and takes him by the hips to bring him between his spread legs. “How do you want me?”

“Hm.” Sirius’ hands slip around to his arse, giving it a firm squeeze before his fingers slip beneath the hem of his shorts, pushing down on the base of the plug and tugging at it, making him shiver before they skim upwards, over his sides and his chest, tweaking his nipples before he takes his face between his hands, thumbing at the corner of his lips. “I think I want your mouth for now. Maybe your arse later, depending on how this goes, but I thought I could fuck your throat while I try to get some work done.”

Remus shudders as a breathy sigh slips through his lips, turning to lick over the pad of Sirius’ thumb before he nods. “Yeah, alright. Do you want me under your desk?”

“Yes, please.” Sirius pushes away from his desk to give him room, grabbing his wand and conjuring a large cushion beneath it before he pushes his robes aside and starts undoing his trousers, shoving them down around his ankles as Remus crawls beneath the desk and settles on his knees, leaning back against the wood panel that goes all the way down to the floor. “Comfortable? Do you have enough room?”

“Mhm,” he answers, licking his lips as Sirius scoots in again and blocks out the light, his thick cock bobbing in front of his face. Remus leans in and runs his tongue over the tip, moaning quietly at the taste of his pre-come, lapping at it a few times before he takes him into his mouth. 

Sirius lets out a relieved sigh above him, some of the tension immediately leeching from his muscles, one hand reaching beneath the desk and tangling in his hair to guide him down, his cock brushing against the back of his throat before he slowly drags him up again. “Do you think you could just do it like that for a little while? Merlin, you feel so fucking good.”

Remus hums his agreement, flushing at the praise, slowly moving his mouth up and down the length of Sirius’ cock as his hand runs through his hair a few times before it returns to the desk. The quiet scratching of a quill and the rustle of parchment fill the room a few moments later, just barely covering the wet slurping noises Remus’ mouth is making. He entertains himself with making Sirius feel good, hollowing his cheeks on each upstroke and suckling at the head before he traces his tongue down the vein on the underside of his cock as he sinks down again, reaching up to wrap one hand around the base of his cock, stroking lightly as the other massages his bollocks, rolling them in his palm and tugging softly as Sirius groans above him. 

It doesn’t take very long before Remus is so turned on that he can barely stand it, panting through his nose and squirming as he squeezes his thighs together, carefully keeping himself at the pace Sirius set as he shivers at the feeling of the plug shifting around inside of him. The dull, barely there sensation isn’t quite enough to get him off, but that doesn’t mean he won’t try his hardest anyway. He thinks for a second about touching himself, but both of his hands are occupied, and his own pleasure doesn’t matter at the moment because he’s here for Sirius to use. 

This goes on for a little while before Sirius reaches beneath the desk and tangles a hand in his hair. “Getting all worked up down there, Moons?”

“Mhm,” he mumbles around the cock in his mouth, squeezing his thighs together and shifting around, the hand in his hair tightening and pulling at his roots before Sirius chuckles and murmurs something that he doesn’t quite catch, and Remus gasps as several things happen at once; the plug in his arse starts vibrating, Sirius uses the hand in his hair to yank him down until his nose is pressed against his pelvis and his cock is throbbing inside his throat, and the tip of a smooth dragonhide leather boot presses against where he’s leaking inside his shorts. 

“Do you like that spell?” Sirius grits out, taking his head in both hands and holding him still as he starts thrusting up into his mouth, letting out a low noise as he moans around him and starts grinding himself against the boot between his legs. “I just picked that one up recently and have been waiting for the perfect time to use it. That’s it, does that feel good baby? I want you to get yourself off and then you can go back to sucking me, okay?”

Remus moans again, squirming around as the plug presses and vibrates against his prostate, his head spinning as he tries to take in tiny breaths through his nose every time Sirius pulls back, barely getting any air before he plunges into his throat again. He gives into his arousal and lets himself fully hump the top of Sirius’ boot, crying out as he comes only a handful of moments later, wetness spreading across the inside of his shorts. 

“Fuck, that’s it, you’re so fucking good for me Moons,” Sirius grunts, the praise sending tingles shooting down Remus’ spine, thrusting into his mouth a few more times before he pulls him down and keeps him there, twitching in his throat as he cancels the spell on the plug and makes it go still once again. Sirius slowly pulls him up until only the head of his cock is resting inside his mouth, stroking tender hands through his hair as he tries to catch his breath. “There we go, do you feel better now?”

Remus hums happily, sucking gently on the head and tonguing at his slit as he leans into the pressure of his hands, melting beneath Sirius’ gentle touch as he catches his breath and comes down, making a little noise in the back of his throat before he resumes the sedate pace he had previously set. Sirius runs his hands through his hair one more time and strokes his thumbs through the wetness on Remus’ cheeks before he returns to his work, the quill once again scratching at the parchment as he bobs his head. 

They repeat this process a few more times over the course of the afternoon, Sirius taking a break to fuck his throat whenever Remus gets turned on enough that he starts squirming again, the plug vibrating inside his arse as he works himself against his boot, giving him affection and praise after every orgasm before he returns to his paperwork. Remus uses his hands throughout, letting his jaw take a break before it can get too sore, resting his cheek against Sirius’ thigh as his hands twist and slide around his length, the front of his shirt clinging to his skin where drool and pre-come have dripped over his chin and down his throat. 

Remus is barely paying attention by the time he hears Sirius sigh above him, his mind hazy and drifting, listening to the sound parchment rustling and the snap of the ink vial closing before he scoots away from the desk. When he peels his eyes open Sirius is smiling down at him, thumbing at the corner of his stretched lips as their eyes meet.

“My paperwork is all done,” Sirius says quietly, running his thumb along his slick lower lip before he pushes it into his mouth alongside his cock, groaning when he licks over the pad of it. “I’m getting close, do you want me to finish in your mouth or your arse?”

Remus thinks about it for a second and hums, sucking harder in lieu of answering, and Sirius grins at him before pulling his thumb free and stroking it along his cheekbone, leaving behind a trail of wetness. He takes his head in both hands, cradling it between his palms, and starts fucking his throat once more. 

Remus lets his mouth hang open, tongue drooping out over his lower lip, relaxed and tired enough that it’s no longer a struggle to keep his throat loose and open as Sirius forces his cock into it. It doesn’t take that much longer before Sirius mutters a warning and pulls him down, the tip of Remus’ nose resting in the neatly trimmed back hair at the base of his cock as it pulses and spills down his throat, and he does his best to swallow so that he doesn’t choke. 

Sirius pulls him off and reaches down beneath the desk to haul Remus up into his lap, kissing his forehead before his hand slips around to the inside of his thigh, fingers stroking over the soaked material at the front of his shorts. “Do you want to get off again, baby?”

“Maybe later,” Remus rasps, he’s hard but he’s not overly concerned about it right now, his throat raw and his voice scraping out like gravel. “Did you finish?”

“Obviously,” Sirius murmurs, nipping at the shell of his ear when he snorts, guiding Remus’ head up so that he can kiss him softly. “I’ve finished all my work, yes. Thank you for helping me focus. Would you like me to take you home now?”

“Please.”

Sirius gathers him up in his arms and stands, cradling him against his chest as he gathers his wand and cloak, striding across the room and tossing floo powder into the grate before he carries him through, the two of them spinning through space for a moment before they step out into their flat. Sirius carries him straight through to the bathroom, setting him on the edge of the sink before he waves his wand and turns to fit the plug into the drain, cranking on the taps.

“What are you doing?” Remus asks in confusion, squinting at Sirius with one eye as he turns and starts rummaging through the cabinet above the toilet. 

“I’m drawing a bath for us, Moonpie,” Sirius answers, pulling out a couple of fluffy towels and a variety of bath products, setting them to the side before he starts stripping out of his robes. “You let me use your mouth for two bloody hours, you deserve a reward after that.”

Remus rubs the back of his hand over his eye as he watches Sirius test the water temperature before dumping half the bag of epsom salts in, yawning quietly and automatically lifting his arms when Sirius turns towards him. Sirius lifts his shirt up and over his head, tossing it to the side before he helps him down from the sink, holding his hips when his knees wobble. Remus’ shorts are peeled down, the fabric sticking to him uncomfortably, and Sirius frees his feet before he reaches between his arse cheeks and gently works the plug out of him, tossing it in the sink to be cleaned later. 

Sirius picks him up again and carries him over to the tub, stepping over the side of it and carefully lowering them both into the water, arranging him so that Remus is sitting between his legs with his back pressed against his chest. “Warm enough?”

“Mhm, feels nice, thank you,” he mumbles, the water washing up over his stomach, sliding down a little so that he can rest his head against Sirius’ shoulder. He blinks slowly and watches as two steaming teacups and a plate with a slice of cake from the fridge come zooming into the room, settling themselves on the edge of the tub. Sirius picks up one of the cups and holds it out for him, kissing his temple as Remus reaches out with both hands to take it, the sweet taste of honey and a healing potion soothing his raw throat when he sips from it. “You’re going to spoil me.”

“That’s the whole point, Moons.” Sirius takes his chin and gently turns his head to the side, leaning down to kiss him, their lips moving against each other softly until he eventually pulls away and brushes his lips over the bridge of his nose. “Drink your tea, baby, it’ll help your throat.”

Remus grumbles but does what he’s told, drinking his tea and eating little bites of cake off the end of the fork that Sirius holds in front of his mouth, craning up to kiss him with chocolate still on his lips. He sighs happily when Sirius sets aside the empty plate and picks up a rag, lathering it with soap before he starts gently running it over his chest and down each of his arms, Remus’ eyes sliding closed as he washes him. 

When Sirius takes his cock in his soapy hand, fondling it and stroking it to hardness, Remus sighs again and turns his head to the side, brushing his lips over the corner of Sirius’ mouth. He turns and kisses him properly, tongue dipping into his mouth and tangling with his as he leisurely wanks him, and when Remus groans and spills into the water Sirius holds him for a few minutes as he dozes before he finishes washing him.

When Sirius is done he spells them both dry, forgoing the towels completely, before he picks him up and carries him into his bedroom. Remus half expects to be fucked now but Sirius just lays him out on his bed and carefully works the plug into him before he crawls in behind him, tucking one arm beneath his neck and throwing the other over his waist, kissing the back of his neck as he pulls the covers up over them and tells him to go to sleep. 

One night they go out for drinks with James, Lily, and Pete.

They end up in some muggle club, flashing lights and cheap drinks with a cloud of smoke that hovers above the dance floor, the five of them cramming into a booth at the back. 

“How’s work going?” James asks him, one arm wrapped around Lily’s waist to hold her in his lap, Pete scrunched in beside them.

“Really well, actually,” Remus answers, taking a sip of his beer as he feels a hand wrap around his right wrist beneath the table, pulling his hand over into Sirius’ lap where he finds him hard as a rock and straining against his trousers. He glances over at him from the corner of his eye and takes a quick look around before he refocuses on James, taking a moment to judge how drunk the three of them are. “The great thing about freelance work is I can plan it around the moons, so there hasn’t been any issue with me not working those days. The pay isn’t bad either.”

“That’s great,” Lily says with a beaming smile, leaning across the table to squeeze Remus’ hand, all while he takes advantage of the shadowy darkness to unzip Sirius’ trousers, fishing his cock out and wrapping his hand around it, shivering a little when it throbs within his grasp. “I’m so happy for you, Remus.”

“Thank you,” he responds, slowly dragging his hand up the length of Sirius’ cock and rubbing his palm over the head before he strokes down again. “How’s your healer training going?”

Lily lights up, her arms waving carelessly as she launches into a story about some mistake one of her fellow trainees made, and Remus nods occasionally as he works his hand up and down, trying to keep the movement contained to his wrist so that no one will notice his arm moving. Peter picks up the conversation after that, thankfully, the five of them talking for hours as Remus’ wrist grows terribly sore, and when it’s finally time for them to leave Sirius casts a notice-me-not and silencing charm before he apparates them home directly from the booth.

“Holy fuck, Moony,” he grits out, the two of them stumbling as they land in the middle of their living room, and Remus barely has a second to get his bearings before he’s shoved to his knees. “I want your mouth.”

It’s fast and hard, Sirius holding his head still as he fucks into his throat, surpising him by coming with a choked groan barely ten minutes later, though Remus supposes that he was wanking him for quite a while. When he’s done Sirius drops to his knees in front of him and kisses him deeply, licking into his mouth and tasting himself on Remus’ tongue, before he pushes him flat on the floor and yanks his trousers down to return the favor, which doesn’t take very long at all. 

When he spills inside his mouth Sirius crawls up his body and shares the taste with him, pushing Remus’ come into his mouth before licking it back out, laying in the cradle of his thighs as they pass it back and forth until they’re simply kissing. Sirius murmurs praise against his lips as he rakes his fingers through his curls, their lips growing split-slicked and swollen the longer they kiss, until he eventually pulls him up off the floor and casts a cursory cleaning charm over them both before Sirius leads him into his bedroom, the two of them curling up together beneath the sheets.

One afternoon he’s perched in Sirius’ lap, leaning back against his chest with his cock settled deeply inside his arse, the coffee table enlarged and pulled over the sofa so that Remus can continue to work while he keeps him warm, when Sirius brushes his lips over the back of his neck and asks, “do you ever think about dating?”

Remus freezes, a pool of ink spreading beneath his quill until he lifts it from the parchment, swallowing roughly before he answers with another question. “In what way?”

“I don’t know, the general sense I guess,” Sirius responds, lifting him up a little and adjusting his position before he settles him in his lap again, grinding up into him with shallow thrusts of his hips. “I feel bad that you’re always here with me, I just wanted to make sure I wasn’t holding you back from anything.”

Remus gnaws on his lower lip, setting his quill aside completely, wondering how to answer truthfully without giving himself away. His feelings for Sirius have grown exponentially over the last few months, finally allowing himself to admit that he’s in love with him, and the thought of dating someone else makes him sick. He wonders if Sirius is asking because he’s found someone that he wants to be with. 

“No,” he eventually rasps, shaking his head. “I like being here with you.”

“I like it too,” Sirius says with a little hum, squeezing his hips and reaching around to stroke his cock a few times before he slaps the outside of Remus’ thigh, chuckling as he jolts and clenches down around him. “Bend over the arm of the sofa? I want to fuck you for a little while.”

“Yeah, alright,” he says, taking off his glasses before he pushes the table aside and folds himself over the arm, bracing his hands against the floor as Sirius straddles his thighs and pushes into him again. The blood rushes to his head as a moan spills from his lips, the pace immediately fast and hard and brutal, one of Sirius’ hands pressing down on his lower back to hold him still as he writhes. 

Sirius doesn’t come, fucking him through two orgasms before he pulls Remus back into his lap, making him drink a glass of water and softly stroking his hands over his chest while he recovers and eventually returns to his work. Sirius grinds up into him gently as he works on his rune translations, his cock twitching angrily inside his arse, and when Remus is done for the day he turns around and rides him until Sirius is spilling inside of him with a shout. 

Sirius pulls him into a tender kiss as he comes down, both arms wrapping around his waist as Remus twines his around his shoulders, the two of them stealing the air from one another’s mouths until his softening cock eventually slips out. Sirius sighs and pulls back, gaze flicking between his eyes before he ducks in to kiss him again.

“Do you want to shower and go out to dinner with me? My treat.”

“Yeah, okay. That sounds nice,” Remus answers, letting himself kiss him one last time before Sirius reaches for his wand, vanishing the mess and casting a healing charm on him. Sirius helps him stand and keeps an arm around his waist when Remus’ legs shake, leading him into the bathroom and stepping into the shower behind him. “Can we go to that place that does the cheesy chips?”

Sirius takes his face between his hands, kissing his cheek and the bridge of his nose before he brushes their lips together, reaching for the shampoo and lathering it between his hands, massaging it into Remus’ soggy curls and scratching at his scalp in a way that his him going crosseyed. “Whatever you want, Moony baby.” 

Remus is once again in Sirius’ office, on his knees beneath his desk and giving him a rimjob as he jerks him off, when the door suddenly flies open and he freezes.

“Hey, Prongs,” Sirius says casually above him, one hand sneaking beneath his desk and fisting in the hair at the back of Remus’ head, tugging a little until he starts licking at his hole again, his hand sliding up and down his length. “What’s up?”

“Why was your door locked, you wanker?” James asks, dropping into the chair on the other side of the desk, his boots thumping against the wooden panel that Remus is hiding behind. 

“Because I’m still trying to work through all the paperwork caused by your partner casting a bunch of half-cocked spells in front of what seems like half of London. Do you know how long these obliviation reports take to fill out?” Sirius gives his hair another little tug, hips twitching as Remus pushes his tongue inside of him, fucking it in and out of him before he draws back to lick over his hole. “Please tell me that he’s cut from the force.”

“No, Scrimgeour said he was justified, unfortunately.” Remus licks his way inside again as James speaks, stifling a groan as Sirius squirms, pursing his lips against his rim and sucking before spearing him open with his tongue once more. “He was reprimanded and sent for additional training, though, so hopefully he learns a little bit about wand control. Are you alright, mate? You’re all slumped down and your eye keeps twitching.”

“I’m just tired,” Sirius answers, yanking at Remus’ hair and guiding his head up to his cock instead, which he greedily swallows down, wondering if James can hear the plug vibrating inside of him. He presses a finger against Sirius’ rim, massaging the outside of it before he pushes into the tight ring, smiling when his thighs tense. He really does love when Sirius wants his arse played with, even if it is more work for him. “It’s all this fucking paperwork, I swear.”

“Yeah, no shit.” James blows out a breath, his boots kicking against the desk again as Remus lowers his head, bringing Sirius’ cock into his throat and swallowing around it. “I’ve been so exhausted by the time I make it home I don’t even have the energy for a shag. Luckily Lily has been just as tired from healer training, so I’m not failing on my husband duties yet.”

Sirius chuckles, the noise covering Remus’ gasped inhale when he comes up for a breath, squeezing the back of his neck as he deep throats him again. “I’m not quite that tired yet.”

“Oh?” James asks curiously as Remus easily pushes a second finger into Sirius, hooking them and dragging his fingertips over his prostate, his cock jumping in his mouth as he does. “Who have you been shagging then?”

“None of your business,” Sirius answers, thrusting up into his mouth with little minute jerks of his hips. “I don’t know what you’ve heard Jamie boy, but I’m a gentleman, we don’t kiss and tell.”

“Oi, you can piss off with that,” James laughs, rising from his chair. “I’m going to go raid the cafeteria for some nibbles, coming with?”

“Nah, I need to finish this.” Sirius pushes him down and keeps him there, making a small noise beneath his breath as Remus presses against his prostate. “Do me a favor and lock the door on your way out, would you? It keeps Moody from coming in here and nagging at me about the state of my dark detectors.”

“Yeah, alright. Don’t work too hard in here, you look like your brain is going to start leaking out your ears,” James calls right before the door slams shut, the locks clicking into place again.

Sirius rolls away from the desk and leans down to look at him, groaning when Remus keeps circling his prostate, pulling him up so that he can kiss him deeply, tongue dipping into his mouth. “You taste like come, Moony baby.”

“Probably because someone had me fuck him over his desk before telling me to eat his arse,” he says teasingly, licking over the head of Sirius’ cock when he realeases him and straightens up again. 

“But you’re just so good at it,” Sirius sighs, tipping his head back against his chair and watching him with burning eyes as Remus closes his lips around his cock and starts bobbing his head, thrusting into his throat a few times before he speaks again. “Fuck, you feel so good. Alright, I need to get back to doing this paperwork, I really wasn’t joking about how much of it there is.”

“Do you want me to keep sucking you off?” he asks, letting Sirius’ cock slip from his mouth, leaning down to mouth at his bollocks, licking over the soft skin beneath them. “Or do you want me to eat you out again?”

“Whatever you want, Moons,” Sirius says, tracing his thumb along his lower lip before he gives him a sharp grin and pushes it into his mouth. “I want your arse when I’m ready to come though.”

Remus spends the rest of the morning like that, alternating between eating Sirius out and sucking him off while fingering him, coming so many times as he clenches around the plug and grinds himself against his boot that he completely loses count. Sirius eventually yanks him out from beneath his desk and turns him around, shoving him against his foe glass so hard that it rattles in its frame, yanking at his trousers so forcefully that a stitch pops free. Remus ends up with cheek resting against the smooth surface and his hands braced against it, one of Sirius’ hands clamped down over his mouth to keep his pleasured screams from escaping as he pounds into him relentlessly, his release splattering all over the shadowy figures in the glass long before finally finishes inside of him.

Sirius holds him for a bit, leaning against his back with arms wrapped around his waist, pressing gentle kisses along his shoulder blades and the back of Remus’ neck before he pulls his softening cock out and works the plug back into him, keeping him full of his come. He twists it around and pushes on it a few times as Remus whines before he lifts him up into his arms. 

“Do you have any plans for this afternoon?” Sirius asks, carrying him back to his desk and sitting with him cradled in his lap, wrapping his robes around him when Remus shivers. 

“Not really,” Remus answers honestly, snuggling down against Sirius’ chest as his magic washes over him, cleaning away the mess on the outside of his body as the tender soreness in his arse and throat fades. Most of his plans revolve around Sirius these days, whether it be hanging out with him or getting fucked by him, he’s at the center of them all. “Why?”

“I still have a little more paperwork to finish, but I was thinking we could maybe go to the museum afterwards,” Sirius says, conjuring a glass and filling it with water before he holds it against his mouth, brushing his lips against Remus’ temple as he drinks. “We haven’t been in a while, and I know how much you love looking at the bones.”

“The fossils,” Remus corrects automatically, turning his head up to look at Sirius before he gives him a bewildered smile and presses a kiss to the corner of his mouth. “That sounds great, yeah.”

“Alright,” Sirius says, smiling and kissing him again before he tucks Remus beneath his chin, one arm wrapped tightly around his waist as the other reaches for his quill. “This shouldn’t take me more than an hour to get done, so why don’t you take a little nap before we go.”

“Okay,” Remus mumbles, eyes already slipping shut, completely worn out from the hours that he spent making Sirius feel good. “Can we go to the gift shop while we’re there? I was looking at that book on paleobotany last time we went, and I have enough money to buy it now.”

“You should have said something, Moons, I would have bought you a book,” Sirius murmurs into his hair, kissing the top of his head. “But sure, baby, whatever you want.”

Remus is woken from sleep one night when he feels the bed dipping beside him, a hand running through his hair as he slits his eyes open and looks over to find Sirius perched on the edge, still in his uniform with a streak of something black along his cheekbone.

“Hey,” Remus rasps, voice deep and crackling, raising his head a little as he runs his eyes over him to check him for injuries. “How’d the raid go?”

“Fine. We got the bastards,” Sirius says, pushing his robes off his shoulders and yanking at the ties of his trousers, pulling his cock free and giving it a few strokes. “I want your mouth for a little while before I fuck you.”

Remus rolls over onto his back at once and scoots down so that he’s lying flat on the bed, mouth hanging open as Sirius climbs over him and straddles his chest, bracing his hands against the headboard before he slides into his mouth, hips rolling quickly as he groans. Remus’ hands slide up his thighs and over his firm, round arse, casting a wordless lubrication charm and petting at his hole until Sirius grunts in approval, working his fingers into him as he pushes into his throat.

When he’s had enough Sirius rolls him over and pulls the plug out of him so quickly that Remus keens as his hips are yanked up off the bed, a hand on the back of his head pressing his face into the mattress as he’s fucked so hard that the headboard slams against the wall with every slap of Sirius’ hips against his arse. Remus has never been quite so grateful of the silencing charms on their flat than he is in that moment, unable to keep himself from wailing.

When he finally finishes inside of him Sirius plugs him again and cleans him up, his healing charm racing through his body, before he curls around Remus and murmurs soft praise to him as he falls back asleep, bringing him breakfast in bed and a brand new book the next morning before he fucks him again.

Things come to a head on a random Thursday afternoon. 

Sirius has the day off of work and Remus has enough of his own work finished that he doesn’t feel bad about pushing the rest of it off for another day. He spends part of the morning sucking Sirius cock before they get dressed and head out, wandering around town and sharing an order of chips before they do the shopping, moving around each other in the kitchen as they put their groceries away and clean up their dinner mess from the night before.

“Want to watch a movie with me?” Sirius asks, turning to him with a little grin, and Remus just smiles at him as he nods.

He isn’t surprised in the least when Sirius pulls his trousers down and works the plug out of him, casting a lubrication charm before guiding Remus down over his lap and pressing the head of his cock against his hole until it slips inside as he gasps at the stretch, pulling him all the way down until he’s fully seated and leaning back against his chest. Sirius kisses the side of his head and pulls a blanket over them, one arm wrapped around Remus’ waist as he uses his wand to send the tape floating over to the VHS player he insisted on buying when they got the television, grinding up into him as he fiddles with the remote. 

“The muggle at the store said this one is really good,” Sirius murmurs in his ear, mouthing at the lobe as he fast forwards through the commercials, hitting play when yellow text starts rolling across the screen and turning up the volume before he tosses the remote aside. “It’s about a space war or something.”

Remus loses track of what's happening in the movie rather quickly, most of his focus on the way Sirius is shallowly thrusting up into him and nibbling at the crook of his neck, giving up on following the plot entirely when some blonde guy loses his robot. He folds his legs up beneath him until his knees are planted on either side of Sirius’ thighs, reaching back to wrap an arm around Sirius’ neck before he starts to roll his hips, a low moan slipping from Remus’ throat as his cock drags against his prostate. 

“Okay, wait, I can’t do this anymore,” Sirius says suddenly after he’s been riding him for a little while, grabbing his hips and lifting Remus off his lap completely before depositing him on the cushion beside him. Remus freezes, startled and confused, his stomach sinking at the upset look on Sirius’ face. “I’m sorry but I can’t.”

“You can’t do… what?” he asks hesitantly, tears pricking at the corners of his eyes when Sirius waves a hand between them. “You- You don’t want to have sex with me anymore? Did I do something wrong?”

“No, Remus,” Sirius groans, and that cuts deep, the tears in his eyes spilling over and streaming down his cheeks. He must have really fucked up if Sirius is calling him by his actual name, he can’t remember the last time he did that. “I just can’t keep having casual, meaningless sex with you. It’s not what I want anymore.”

“Oh,” Remus says, sniffling as he rubs his nose on the back of his hand, realizing all at once what’s happening here. “You want a real relationship and don’t want me standing in the way of that. That’s, um- That’s fine-” He winces as his voice cracks, curling in on himself as he wraps his arms around his knees. “I know that I’m not what you’re looking for in a partner, I understand. Do you want me to move out, then? Because I can, I don’t want to get in the way whenever you find a partner to-”

“Wait,” Sirius says, cupping his face in his hands and forcing him to look up, his face doing something complicated. “Moony, baby, what the fuck are you going on about?”

“You- You just said you don’t want to have sex with me anymore because you want to find a relationship.”

Sirius squeezes his eyes closed for a second, huffing out a breath before he shakes his head. “No, I said I don’t want to have casual, meaningless sex anymore, and yes, I do want a relationship… with you. But you’re just in it for the free rent, even though I’ve been telling you from the beginning that you don’t have to pay me anything to live here.”

“No you don’t,” Remus says incredulously, gaping up at him in shock before his brain catches up with the rest of his sentence. “No, I’m not. I fucking love having sex with you, not paying you rent is just a bonus on top of that.”

“You-” Sirius blinks a few times and groans, reaching up to rub at his eyes. “Okay, I think that both of us might have totally different ideas of what’s happening here.”

“I- I think you might be right, yeah,” Remus says, the two of them looking at each other for a long moment before his eyes drop to Sirius’ still hard cock. “So you do want to have sex with me.”

“Moons, I spend several hours a day inside of your body, do you really think I’d do that if I didn’t want to have sex with you?!”

“I mean, at a certain point a hole is a hole,” he says with a little shrug as Sirius glares at him, swinging a leg over his thighs and sliding back onto his lap, face-to-face this time. Remus reaches behind himself and guides Sirius’ cock into his arse, where it belongs, letting out a quiet moan as he sinks down onto it. Something explodes on the television as he hesitantly raises his arms, looping them around Sirius’ shoulders as his hands land on his hips. “I thought you just wanted to have sex with me. You agreed to this whole arrangement so quickly.”

“I’ve had a crush on you for a few years,” Sirius admits after a moment, his nose wrinkling when Remus makes a little noise of surprise. 

“But then I tried asking you out in seventh year and you brushed me off so completely that I assumed you didn’t feel that way about me. When you suggested this arrangement I thought… Well, I don’t really know what I thought. Part of me was just excited at the idea of getting off on a regular basis, but then the more time I spent with you the more those feelings grew until just sex wasn’t enough for me anymore. I want to date you, Moons, I want to take care of you, but the only time I can get away with it is after we have sex. I noticed that you didn’t put up a fuss about me doing things for you when I worked it into the aftercare, which is why I always try to take you out afterwards.”

“Pads, we have sex constantly, everything we do is after sex,” Remus says, staring at him in confusion and trying to figure out when he asked him out when it suddenly dawns on him, his lips curling into a scowl as he smacks his hand against his shoulder. “You didn’t ask me out, you fucking idiot, you were stoned off your arse and said ‘Hogsmeade?’ To which I replied yes, all four of us were going together the next day, and you never brought it up again. That was you trying to ask me on a date?”

“I- Yeah.” Sirius squeezes his hips, hands sliding around to his lower back and slipping between his arse cheeks to pet at where he’s stretched open around him, grinding up into him as he shrugs one shoulder. “I’d tried flirting with you countless times before that and you always brushed me off, so it was sort of a last ditch effort on my part.”

“Sirius Orion Black you flirt with everything that moves. For fucks sake, I watched you flirt with a postbox one night while you were pissed, why the fuck would I assume that you were flirting with me in earnest?”

“Oh.” Sirius looks genuinely thrown off by that, his eyes going distant for a moment before he snaps back to the present. “I never really thought about that before.”

“Yeah, obviously.” 

Sirius looks uncharacteristically nervous, raising a hand to his cheek and cupping it in his palm, eyes flicking between his. “Do you want to be with me?”

“Pads, cariad, I’ve wanted to be with you for fucking years. I didn’t think you wanted me,” Remus admits, watching as Sirius’ eyes light up and his face spreads in a beaming smile, letting himself be pulled in for a kiss and quickly losing himself in Sirius’ mouth until a thought occurs to him and he jerks backwards again. “I don’t want you to stop using me, though. I still want you to take me whenever, however, and wherever you want. I cannot explain to you how much I love it when you just use my body to get yourself off.”

“Merlin wept, you are so fucking perfect,” Sirius groans, grabbing a handful of his hair and yanking him in to smash their mouths together again, snapping his hips up as Remus cries out against his lips. “Yeah, Moony baby, I’ll keep using you. Sliding into your tight little arse whenever I want, pushing you to your knees and fucking your throat when you’re in the middle of work or trying to do something, using your holes to keep my cock warm, is that what you want?”

“Yes,” Remus gasps, whining in protest when Sirius suddenly lifts him and deposits him on the cushion beside him once again, the sound bleeding into a moan when he crawls on top of him. Sirius hooks his elbows beneath his legs and practically folds him in half, pinning Remus’ knees next to ears as he slides back into him and starts fucking him fast. “Yes, Pads, please-”

“So fucking perfect,” Sirius grits out, their skin slapping together as he drives into him, groaning quietly as Remus lets out wailed moan and arches up off the sofa. “Letting me use your body for hours, never complaining no matter how hard I fuck you, doing whatever the fuck I tell you to do, you are a goddamn dream, baby.”

Remus lets out a breathless shriek as he comes, his release splattering across his chest and the lower part of his face from the position he’s in, Sirius fucking him through that orgasm and straight into the next, pulling him up into his lap and letting him collapse against his chest as he attempts to catch his breath. 

He can feel the way his arse his still pulsing around Sirius’ cock, shuddering as the aftershocks roll through him, mouthing at Sirius’ collarbone and sinking his teeth into it lightly as he’s wanted to for ages now. Remus was always worried that it was something that would feel too personal for someone that Sirius was simply fucking, pulling off with a wet pop to see the mark he left behind before he tucks his face against Sirius’ throat, whimpering quietly as he grinds up into him.

“Does that mean that we’re dating now?” Remus asks shyly after a little while, raising his head when Sirius tucks a finger beneath his chin and sighing when he brushes their mouths together. 

“Yeah, Moons, we’re dating,” Sirius murmurs against his lips, licking between them and stealing his breath before he pulls away again. “Boyfriends, partners, whatever you want to call it.”

“I don’t care, as long as I’m yours,” he says, Sirius letting out a gritty groan before he grabs his waist and lifts him, bouncing him up and down on his cock as Remus’ eyes roll back in his head and a whine rattles around in his throat. “Fuck, cariad, please, feels so good-”

“Yeah, does it feel good when I use you, Moons?” Sirius growls, thrusting up into him, Remus’ head ragdolling back and forth as he’s lifted and dropped. “Just a little toy for me to get off into, right?”

His orgasm catches him completely by surprise, Remus screaming as his cock kicks and spills between them, his vision blacking out entirely from the force of it.

When Sirius finally comes what feels like hours later is Remus fucked out and draped limply over the back of the sofa with his boyfriend kneeling behind him, the telly playing static because the movie ended ages ago, he can’t help but to sigh happily as Sirius trails soft kisses across his shoulder blades and back. Sirius wraps his arms around his waist before he gingerly pulls out, kissing Remus’ cheek in apology when he whines at the loss, gathering him into his arms and pressing their lips together softly.

They talk things through later that night, after they’ve eaten dinner and showered before curling up in bed together, the tips of their noses brushing as they discuss the feelings they’ve apparently both been harboring for each each other and what they want from the relationship, kissing between words as Remus’ hand slides up and down Sirius’ straining cock. 

Remus once again stresses how much he enjoys being used before letting himself open up about his insecurities regarding himself and his money issues, Sirius soothing away his worries when he expresses not feeling like he’s good enough for him, blushing a little as he explains how deeply his feelings run without ever quite putting a name to them. Remus will tell him soon, and he’s pretty sure Sirius might already know from the way his eyes gleam in the darkness, but for now he’s happy to leave it at that. 

In return, Sirius tells him that he wants to take care of him and buy him things, that he loves their arrangement as much as Remus does and that the mere idea of fucking him whenever he wants gets him going like nothing else but that he wants more out of it. Sirius wants dates and hand holding and being able to pay him compliments, as well as handling all of the bills, and Remus reluctantly agrees to allow himself to be doted on more often without complaint. 

They both talk about the way they’ve tried to keep each other emotionally distant to prevent themselves from being hurt, Sirius by not kissing him during sex or by keeping his attention focused elsewhere and Remus by thinking about it all as temporary, that Sirius was simply using him until someone better came along, expecting himself to be tossed aside at any moment despite the fact that they’ve been best friends for years. They whisper reassurances to each other, making promises to each other that they’ll start communicating more, that they’ll speak up when something is bothering them. 

Sirius eventually rolls over and presses into the cradle of his thighs, kissing him as he pushes into him once again, Remus sighing into his mouth as he gently rocks their hips together. The sex is slow and sweet, the first time they’ve ever fucked like this, several orgasms washing over him as Sirius holds his face in his hands and tenderly licks into his mouth. Remus is so strung out and exhausted by the time Sirius finally comes that he falls asleep the moment he hears him grunt and feels him spilling inside of him. 

Remus is washing the dishes the next morning, scrubbing distractedly at a pan and staring off into space, worrying himself sick as he wonders if the fact that they’re together now will change the way Sirius treats him, even if just last night he had insisted that it wouldn’t. He loves their sex life, and his stomach clenches uncomfortably at the thought of all that changing now, wondering if Sirius will start treating him more gently or asking to have sex with him instead of demanding it, which is the absolute last thing that he wants. 

That is, of course, until Sirius wanders into the room.

“Morning, Moony baby,” he says, opening the fridge and drinking milk straight out of the carton before he takes the pan from Remus’ hands and drops it into the sink, splashing water everywhere as he looks at him with heated eyes. “I want your mouth.”

Sirius' words catch him off guard for a single second, a beaming smile spreading across Remus’ face as he ducks forward to press their lips together before he drops to his knees so quickly that pain shoots up his legs as he lands on the tiles with a crack. Sirius casts a belated cushioning charm as Remus yanks his pajamas down and swallows him up to the hilt, his boyfriend groaning and leaning back against the counter as he starts bobbing his head.

When his jaw is starting to get sore Sirius picks him up and bends him over the kitchen table, a pile parchment and books for his current freelance job getting shoved to the floor, and Remis moans as his pants are unceremoniously tugged down over his arse and the plug pulled out with little fanfare, the sensation of wetness spreading through his arse as Sirius mutters the lubrication charm. Sirius pushes into him with a low groan before he starts fucking him so hard that the entire table rattles, the legs screeching against the floor, yanking Remus back by the hips into each rough thrust.

“Want to go out to breakfast?” Sirius pants against the nape of his neck once he’s finally come, both arms wrapped tightly around Remus’ waist, mouthing at where his hair is clinging to his sweat soaked skin. “I thought we could check out that new place that opened up the road.”

“Yeah,” Remus rasps, shivering as Sirius pulls out of him, remaining bent over the table as he cleans the plug and pushes it back into him, twisting it around and playing with it for a few moments the way he seems to love doing before he flicks the base of it and laughs as he squeaks. Sirius’ magic washes over him, cleaning away the sticky fluids between his legs and all over his stomach, his arse and throat tingling as the healing charm races through him. “I have to get some work done at some point today, though.”

“That’s fine, I have a patrol shift this afternoon,” Sirius says, pulling him up and turning him around so that he can kiss him, cradling Remus’ head in his palm as he slides their lips together, the other looped around his waist to keep him upright when his legs refuse to hold his weight. “But maybe you can come to my office this evening? I’m behind on paperwork again.”

Remus smiles against his mouth and kisses him again.
