Notes Thank you @luminousgloom and @nachodiablo for helping me!! This is the most smut I have ever written, I don’t know how it happened. Actually, I do know. It’s thanks to the anonymous prompter! Thanks to you too! :) I hope I delivered, since this is a kink that could be written in a few different ways, and I’m not sure what was on your mind. Also, there's some art at the very end! ;) The first time Sirius notices Regulus look the Marauders’ way and let his eyes linger, Sirius doesn’t think anything of it. In fact, he doesn’t even realize he’s counting the times it happens until he catches Regulus look a fourth time. This time they’re out by the lake, and James is flying over it in his boxers while the rest of them are laughing along. Almost everybody’s looking at James, save for a few students blushing and coyly looking away. And of course the Slytherins frowning and muttering amongst each other about their annoyance. And then… And then there’s Regulus. He’s not joining in the conversation with the Slytherin crowd, and he’s not looking at James. He’s looking at Sirius, Remus and Peter. Staring, even. Sirius tries to read Regulus’ expression but his younger brother’s too far, and Sirius doesn’t want to spare him more than sideways glances. It’s been weeks since they’ve even owled, he’s not about to be the one to break the silence. It keeps happening so frequently, that Sirius gives up on counting, even subconsciously. He’s used to people staring at them - of course he is, they’re Sirius Black and James Potter - but something about his own brother doing it unsettles him. There’s also the tiny detail that’s been bothering him from the beginning: Why, after five years of barely acknowledging their popularity, would Regulus suddenly care? He’s not one of their fans, and he’s obviously not one of the students lusting after Sirius. So what’s his angle, Sirius wonders, Why’s he being like this? Is it because we talk even less now? He didn’t seem to care, earlier. Weeks go on with more of the same, and every time Sirius is about to forget about Regulus’ whole existence, including his newfound interest with the Marauders, Regulus seems to appear out of nowhere. He’s even there in class sometimes, after October, when Kerenhappuch had instructed for Regulus to join the seventh years’ DADA classes as he was too advanced for the sixths’.   ===============================================================================     Given that he had caught Regulus so many times - not that it could be called catching, when Regulus wasn’t hiding it in the least - he should’ve put the pieces together much, much earlier than he had. “Smartest wizards of their age,” Dumbledore had called them once, and McGonagall had huffed and told him “cleverness will only get them so far.” But Sirius doesn’t feel smart, or clever. He feels like an imbecile. He’d spent as long as he could watching James snog Evans on the common room couch, but there’s only so much a man could take. So he’d gone to the library, hoping to lure Remus away from his dusty books. He’d been ready for an argument to get the werewolf away from the library, maybe some seduction, or making Remus’ books float away from him… He certainly had not expected to see this. The corner of Remus’ mouth is curled in amusement, but his eyes are on the parchment as he writes slowly, his left hand spread over a book. He has such nice, large hands,Sirius can’t help but think, even at a moment like this. The werewolf has a slight blush on his cheeks, as if he’s heard a particularly dirty joke, or gotten reprimanded by a professor. The most interesting - and infuriating - part of this scene though, is the person next to him. Regulus is sat next to Remus, a mostly-blank piece of parchment in front of him, and he’s grinning slyly at Remus as he watches the werewolf write. “Remus?” Sirius spits out, not bothering to acknowledge his brother. His voice has enough venom in it that Remus’ head immediately snaps up. He doesn’t look scared, but Sirius can hear the gears turning in his head as he does a quick calculation. “Hey Sirius,” Remus says lightly, not looking at Regulus. “Prongs bore you already?” He’s speaking as if he doesn’t have a snake right next to him. “Why, need more time to waste on snakes?” Sirius asks dangerously, taking another step towards their table. “He’s your brother,” Remus says, voice calm but firm. Sirius loves that about Remus: even when he knowshow furious Sirius is, even when he knowsSirius is about to blow, he doesn’t hold back. Sirius never, ever feels like he has any real power, or like he can strike any blow to Remus that won’t be met with the same ferocity. Remus does like to keep his friends happy, and is open to compromise, but he doesn’t let them get away with things, not when they matter. “Yes, well,” Sirius drawls, watching Remus pack to leave. “He’d be smart to remember that.” He turns slowly towards Regulus who, to Sirius’ surprise, is looking back at him coldly, but without fear. “What I’m like.” The words ‘I don’t share’ go unspoken, but he knows Regulus has heard them.   ===============================================================================   Sirius and Remus have never talked about exclusivity the way one of the boys he was seeing had tried to, once. They’d never put a name on what they were doing either - Sirius didn’t even think it needed a name, not until he’d had the urge to tell his brother to lay off his boyfriend. Is that what they are? Boyfriends? Seems like a juvenile word. Unnecessary categorization. Sirius watches Regulus smile and nod at Remus as he walks into the DADA classroom and feels like going over and snapping Regulus’ wand in half. He listens to Remus talk about how it wouldn’t be a bad thing, really, if he spoke to his brother again. They’re family, apparently. Sirius doesn’t bother answering him. He stomps down the anger that burns in his chest when Regulus gets a question right in class and Remus smiles at him, Regulus grinning right back. They’re not flirting, not really. Regulus just has a crush on Remus. Nothing to be worried about. Except… Except now Sirius is thinking about it. About them. He knows they haven’t done anything — he’s made sure never ever to let them be alone again. But the images play behind his eyelids anyway, when he closes his eyes, in the privacy of his own bed. He sees Regulus kissing Remus’ lips, gliding a hand over on his side, squeezing right under his ribs the way Sirius likes to. He sees Remus beaming at him, eyes looking all over Regulus’ naked body hungrily. And when his devious mind supplies an image of Remus sliding his tongue behind Regulus’ balls, Sirius comes harder than he ever had before while wanking. He breathes heavily and stares at the ceiling of his four-poster, wondering what the fuck that was about, for several minutes. Then the stickiness starts bothering him, and he gets up to get clean.   ===============================================================================   He can’t help himself. At first, he tells himself it was because Regulus looks almost exactly like Sirius, and the fantasies are in fact of Sirius and Remus, but he knows it’s not true. He’s started wanking at least twice a day and even for an eighteen year old it’s getting sort of ridiculous, considering the fact that he’s getting consistent sex with Remus on top. Not one DADA class ends without Sirius rushing off to the loo to wank to the thought of Regulus bending Remus over and fucking him, in whatever he was wearing under his robes that day. The more details he adds, the more real it feels, and the harder he gets. It takes a month for him to gather up the courage to mention it to Remus, and he does it in a moment of passion, rather than a conscious effort at having a Talk. Not that they have those. He’s thrusting into Remus, who’s on all fours, with all his strength when he finds the words. “Fuck,” he breathes out, “You love cock, don’t you?” And it’s true. Remus loves getting fucked. Sure, he likes fucking Sirius too, but not the way he loves having Sirius’ cock in him. There’s a reason they end up like this more than the other way around. Sirius doesn’t have a preference either way, but he’s not going to complain. Remus feels amazing around him, opening up, just for Sirius. They do dirty talk sometimes, and Remus doesn’t skip a beat. “Yes, yes,” he replies hurriedly, voice stilted a bit, as they grind together. “Love your cock.” “Not just mine,” Sirius hisses as he finishes a particularly forceful thrust, and tightens his grip on Remus to hold him in place a bit better. This time Sirius’ sentence does give Remus a pause, but not a long one. “No, any cock,” he says in the end. “Fuck— Remus— I—” Before either of them can talk any more, Sirius comes with a few jerky, short thrusts. He shifts slightly, trying to catch his breath, and starts jerking Remus off, still buried deep in him. It takes him almost a full minute before he thinks to continue to talk to help bring Remus over the edge. “Slag,” he says, and apparently doesn’t need to elaborate because Remus comes all over his hand and sheets right after.   ===============================================================================   They still have what Sirius calls “regular” sex, but as the days go on, more and more often, they get into scenes where Sirius tells Remus about what a whore he is. Whether Sirius is the one fucking Remus or the other way around, the humiliation part of the roleplay always goes towards Remus’ way, and they both seem to enjoy that well enough. Sirius still feels like it’s far, far from enough. It’s like scratching right next to an itch. It’s not hitting the right spot, he can’t get any real relief, and by Merlin, he can’t stop imagining Regulus fucking Remus. Often, even while he’s in the middle of sex with Remus, he’ll think of Regulus in his place, and come to the thought of Remus using Regulus. It doesn’t hit him that he’s drawn the wrong conclusion about his own desire, until he’s slapped in the face with it. Almost literally. Remus is on his knees on the bed, and Sirius is kneeling on the floor next to it, one of their favored positions for blowies. Remus holds his cock in his right hand, steady, then smacks him across the face with it instead of leading it towards Sirius’ mouth. Sirius gasps, half in shock of the act itself, and half because his half-stiffy is now at full attention. “You know it doesn’t matter who you are,” Remus says, voice eerily calm, and lifts his cock, drawing Sirius in towards his balls with his other hand. “Maybe this time I’ll let you be the one to prepare me,” he continues, spreading his legs apart a bit more, “But let someone else fuck me.” Sirius moans, licking Remus’ balls and the base of his cock sloppily. It’s not Remus that Sirius gets off on seeing humiliated. It’s himself. He wants to serve Remus on a silver platter - for the lack of a better term - for his brother to enjoy. And calling Remus a slag isn’t to demean him,it’s to show that Sirius doesn’t matter. He’s just a cock, something to serve Remus. And Remus could get that somewhere else, if he wanted to. Remus is spread across the bed now, legs open wide, and Sirius laps at his entrance and perineum, drawing delicious, husky groans from the other boy. He fumbles around the bed until he finds the vial of lube, then pours some on his left hand generously. Remus holds up his legs wantonly, as if he can’t wait to have Sirius in him. Or anybody else. He just wants sex.Sirius shivers as he thinks it. A very small part of him still able to function despite the lack of blood going to his brain tries to be jealous, to want to fight off anybody else who might get close to Remus. But his cock loves the idea of somebody else fucking Remus, and merely twitches happily in response to the thought. If anything, his jealousy adds to the hotness of it. Maybe he’d be tied somewhere, unable to stop Regulus from having his way with Remus. Have to watch them. Watch them flirt and smile and fuck. He shuffles and finds a rather uncomfortable position that lets him get off Remus and himself at the same time. His ass is raised up and his face is buried in Remus’ crotch. ‘Come for me, Lupin,’ Regulus is saying in his mind. ‘Come on my cock. Show my arrogant brother how much you want me.’ Sirius comes before Remus does.   ===============================================================================   It’s spring by the time either of them truly voice what they’re doing out loud and, unsurprisingly, it’s Remus. “So, Padfoot,” he says casually, stroking Sirius’ shoulder idly. They’ve just had sex, and Sirius is curled up with his head on Remus’ chest. “Is that something you want?” “What?” “Don’t play ignorant, Pads. Doesn’t suit you,” Remus chuckles. When Sirius still doesn’t answer, he elaborates: “Have another bloke with us, in bed?” Sirius draws a large breath. “Not really,” he says. That’s not a lie. He doesn’t want just another bloke. He wants Regulus. His spent cock attempts a twitch at the thought. As usual, Remus sees right through him. “You sure? You sound as if you’re imagining something rather specific, whenever we…” He searches for the right word. “Play.” Sirius stays quiet. He can hear his heart beating, the way he does when he runs too far too fast. Remus shrugs his shoulder, making Sirius’ body move with it. “Oi, I’m talking to you.” “I…” For the first time in his life that he can remember, Sirius honestly doesn’t know what to say. How does he put what he wants into words? ‘I want to watch my brother fuck you’ comes to mind, but somehow he doubts Remus would like that, even if he believed Sirius. Thankfully, Remus doesn’t push it, and Sirius assumes that’s that. They clean up and go to the Great Hall to meet up with the rest for lunch.   ===============================================================================   “Is it the fact that you look so much alike?” Remus asks, and Sirius’ breath catches. He tells his body to keep breathing, but it doesn’t not until all his held up breath comes out in one big shuddering sigh. “What?” Sirius looks up at Remus, but his friend - boyfriend?- is staring right below Sirius’ chin, avoiding his eyes. He doesn’t look embarrassed, but Sirius can tell that it’s not easy to get the words out. As if Sirius will flee at a moment’s notice. Sirius Black doesn’t run. “I’ve seen you look,” Remus continues quietly, “At him, then at me.” He looks up at Sirius now, and must see something in Sirius’ eyes that gives him courage because the next words are as frank and straight-forward as Sirius has ever seen him utter. “D’you want me to fuck Regulus?” Of course he’s noticed,Sirius thinks, Moony always knows what we’re up to. Sirius hesitates only for a moment before finding his Gryffindor courage and yes, the fact that there isn’t much blood up north at the moment is helping him along. “No,” he breathes out, putting his hands up to squeeze Remus on his sides. “I want him to fuck you.” “Fuck,” Remus breathes out, eyes widening, and Sirius feels Remus’ cock move on his stomach. He likes that idea too. A flash of jealousy runs through Sirius, and he growls, flipping them over. Remus is complacent, but it seems mostly due to his mind being elsewhere than actual surrender. And when Sirius is licking and sucking his way down Remus’ throat, all the werewolf does is let out soft whimpers and short breaths. Sirius considers getting up for more lube, but decides against it. He lines their cocks up and the lube they had rather generously poured on Remus’ cock earlier allows for slick, comfortable rubbing. He draws it out, enjoying both of their bodies jerking and moving in sync. They kiss lazily, and neither of them talk for a long time, not until Sirius’ abs start to complain about the work-out. “Sirius,” Remus says finally. His voice isn’t loud, but after the minutes filled with only grunts and moans, it startles Sirius. “Y-yeah?” he groans out, reaching his hand between them to help them along before he gets a cramp. He squeezes their cocks and his eyes flutter closed, but he forces them back open to look at Remus. His gorgeous boyfriend, writhing and thrusting his hips below him. For a few seconds, Remus says nothing, and only looks at Sirius, his eyes dark and intense. He gives his lips a quick lick, a gesture Sirius has seen him do sometimes when he’s stalling for time when answering someone. When he starts speaking again, his expression is almost devilish, as if he’s about to tell Sirius about a particularly cruel prank idea. “Are you not allowed to fuck me, anymore?” the devil says, “Is it only Regulus that gets to do that?” Sirius’ throat goes dry, and he feels frozen on the spot by the words, except his left hand doesn’t seem to care, and keeps steadily moving on top of their cocks. His right arm, shaking with his weight now, doesn’t seem to mind the situation either, because fuck it feels so good. Flashes of Regulus fucking Remus fast and hard come to his mind, of the two lost in pleasure. He can’t even force his eyes open this time, because what he’s seeing in his mind is hypnotizing. Remus would look gorgeous, as he always does, moving easily with Regulus. “That why you’re rutting against me like a bitch, instead of fucking the hole you’ve prepared?” Fuck. That shouldn’t be so hot. Sirius’ right arm finally gives in, and he falls down towards Remus, his weight now on his forearm on the bed, with only an inch between their bodies. He’s already coming with such force that his mind is almost blank by the time Remus continues “Prepared me for Regulus, haven’t you?” He wrenches his left hand out from between them, and breathes heavily for a little while, before crawling down Remus’ body wordlessly, and putting his head on his right thigh. He looks up, expecting to see Remus smiling down at him fondly as he usually does, but Remus looks hungry and demanding, nothing gentle about the way he props himself up on his elbows and gazes down at Sirius. He starts to move one hand to bring himself off, but Sirius beats him to it, and starts working Remus’ cock as if it’s the only thing that matters. And it is. So he puts two fingers into Remus, fucking him with them, and keeps jerking his cock until Remus comes with a barely-audible groan, giving Sirius no warning to either bring his face away or grab a flannel to catch the come. By the time Remus is done and Sirius looks up, there’s come running down his cheek, and he can feel some on his hair and right eyebrow too. Some of it even managed to splatter into his mouth. Now, now Remus is looking down at him with the kind smile that Sirius is used to. “Gorgeous,” Remus says with conviction, and as much as Sirius would like to contradict him, tell him he’sthe gorgeous one, his mind’s too occupied thinking about just how bloody fucked up this all is. He just came thinking about his brother fucking Remus - and yes, he’d done that before, but this time Remus had known.He’d added to the fantasy, talking Sirius through it. Loving it. After a quick cleansing spell, Sirius settles on the bed next to Remus, who’s looking at him with a mixture of amusement and wariness. “You OK?” Remus asks. “I want to do it,” Sirius says, and only realizes what he’s saying after the words are already out. Funny how that keeps happening to him, both in and out of bed. Usually not with consequences as fucked up and embarrassing as this time, though… “Alright.”   ===============================================================================   The problem is, he doesn’t have much time to get himself ready. Remus J. Lupin, the annoyingly crafty and efficient bugger, has set it all up in less than two days. He tells Sirius casually over breakfast the next Wednesday: “We have a date with the Room of Requirement this afternoon.” James rolls his eyes, and Peter pretends not to hear. It’s not until Remus glances at the Slytherin table, then at Sirius, that the sickle drops. “Oh,” Sirius says, then stuffs his face with potatoes to avoid having to say anything more articulate. At first he tries to hold off on wanking, but then decides that it would actually be beneficial to come as many times as he can before the actual event, so make sure he can take his time and enjoy it. By the time the last class rolls around, he’s come three times, and it’s started to hurt to touch his cock. He wonders if he’s going to have trouble when— Fuck. Are we actually going to go through with this? He gives Remus a glance, but his friend is innocently listening to Flitwick and taking notes, as if they’re not less than two hours away from doing the most debauched thing Sirius can think of. Well, almost. Sirius wants to ask what time exactly Remus has agreed to, for the— With— He can’t even think it in full sentences, and is glad he’s not a blusher. James gives him a curious look anyway, and Sirius wonders what his face looks like, if even James noticed. He stares intently at Flitwick, willing his face to look neutral. James passes a note across from him and to Remus. Sirius glances at it for a second as Remus returns it.   ‘Will you be at dinner?’James has written in his neat scrawl. ‘No. Plans right after this.’Remus’ cursive replies.   Sirius gulps, passing the note along. Right after this. They’d talked about this at length, the day before. When it had all still been hypothetical. Hot. They’d even talked about rules and restrictions, going through scenarios as if preparing for a NEWT exam. And just like exam preparation, Sirius had ignored most of it, just humming and agreeing with Remus. All hypothetical, after all. What if Regulus doesn’t want to? Not bloody likely, I’ve seen the way he looks at Remus.What if he tells his friends? Nobody would believe him. Sirius Black doesn’t share.What if what if what if. The only question that had given Sirius pause had been the one about what Remus should do if Regulus wanted to be rimmed. After a moment’s consideration, Sirius had told resolutely that anything he and Remus hadn’t already done, was off limits. Remus had simply nodded. But now… Now it was all too real. They were about to— Regulus was going to— Bloody hell. As they’re leaving the class room, Remus nods his head towards James, giving Sirius a look. When Sirius looks back at him puzzled, Remus rolls his eyes and mimes putting on a hood. Oh, right. “Hey Prongs,” Sirius says, remembering the task he’d been given earlier by Remus. “Mind if I borrow the cloak?” James looks at Sirius suspiciously, but doesn’t slow down his walk. “What d’you need it for? Don’t you have plans with Remus tonight?” When in doubt, tell the truth,Sirius thinks. He wiggles his eyebrows at James, and grins. “We’re kinky buggers, what can I say?” At that, James does stop walking. “Padfoot, if you so much as think about having sex in my dad’s cloak, Merlin help me, I—” “Oh, keep your hair on,” Sirius says, rolling his eyes. He starts walking again slowly, and James follows suit, Remus and Peter trailing behind them as usual. “Just need it to get where we need to go, is all.” “U-huh,” James says disbelievingly, but doesn’t press. “Fine.” Sirius barks out a laugh and claps James on his shoulder, looking as relaxed as he possibly can while his heart is beating so loud he’s pretty sure his chest is moving right along with it. He glances at Remus who’s smiling serenely down at the book he’s reading while walking. Merlin help me,Sirius thinks.   ===============================================================================   They’ve decided that the first time this happens - The only time,Sirius thinks, finding the prospect of going through with this a second time too unlikely - that Sirius would be under the invisibility cloak. He’d be under a silencing spell, but of his own casting, mostly to try to keep random outbursts at bay, while still giving him control to come out and stop everything if he wanted. They’d tried it a few times, to see if Sirius could take off the spell wordlessly, and it had worked. Now all Sirius had to do was go to the Room of Requirement with Remus before Regulus got there, get under the invisibility cloak, and watch. And sit still. Not make any noise, or jump out to give Regulus boils all over his stupid face. It’s surprisingly easy to stomp down the jealous thoughts, though, as long as he focuses on what Remus will look like. Beautiful, gorgeous Remus, with his head thrown back, swollen lips parted, panting and enjoying himself. Riding someone - Regulus -someone just like Sirius, but not quite. The thought of Remus getting off without him makes Sirius so hard he’s afraid he’s going to hurt his dick irrevocably by the time this whole ordeal’s over. Especially if he’s meant to keep quiet, he can’t wank himself off, even under the invisibility cloak. They’d hear him. And besides, he’s not eager to go against James’ wishes and soil his cloak. Afterwards… Afterwards, he’ll have Remus suck him off and won’t that be the perfect conclusion to the evening? While his mind’s been wandering, they’ve already arrived at the Room of Requirement, and Remus gives him a quick but passionate kiss before shooing him away to the armchair in the corner. To Sirius’ surprise, Remus walks out of the room, saying he’ll be back. By the time Regulus and he enter the room again, Sirius is antsy and has to consciously stop his leg from tapping. Regulus looks wary, surveying the room, but he doesn’t look afraid. “Sure it’s not a prank, Lupin?” he asks, slowly unbuttoning his robes regardless. “I don’t think you understand how pranks work, Reggie,” Remus drawls, and Sirius wonders when Remus started talking to strangers the way he talks to his friends. He thought only the Marauders got that confident attitude from the werewolf. Not that Regulus is a stranger… “Oh, don’t call me that,” Regulus says, and despite the irritated, sneering tone he’s going for, he sounds a bit like a whining kid. Sirius tries not to think about doing this with his little brother. He’s of age,he reminds himself, shaking his head side to side a bit, like he does as Padfoot when he smells something vile. “You’ll remind me of my dear brother.” And just like that, Regulus is back to being the snake that he is. Not a minute in, and he’s looking for a way to get one over Remus. But Remus is unperturbed, and merely raises his eyebrows. “Sirius calls you that?” he asks innocently. “And where is he tonight?” Regulus asks. His confident stance is ruined by his nervous glance around the room. He’s expecting to be pranked, or hurt, probably. “Doesn’t matter,” Remus responds easily, and takes off his own robes, and makes a show of looking at Regulus appreciatively. “Got sick of you, has he?” Regulus takes off his tie as gracelessly as a Black can, and grins. “No.” Regulus’ eyes widen and shine so brightly that Sirius can see his whole face light up from five feet away. Cunt,he thinks unkindly. The fact that Regulus would get off on this hadn’t exactly occurred to Sirius. Yes, sure, he’d be there, and do things, but… Regulus thought he was actually hurting Sirius somehow, taking his toy, when this wasn’t about Regulus at all. Sirius wills himself to calm down, for once in his life, so he can live out his fantasy. He closes his eyes and thinks up images of them having sex for a little while, before opening his eyes again because damned if he’s going to miss a second of this that he doesn’t have to. As if sensing Sirius’ impatience, Remus takes off his clothes so quickly, down to his pants, that Regulus is left staring. “Don’t beat around the bush, do you?” he asks breathlessly, and looks Remus up and down, eyes wide in interest and, if the bulge in his crotch is anything to go by, lust. “Lost interest?” Remus drawls, pretending nonchalance, but Sirius knows better. Remus has never been one to show off his body, and being on the spot like this can’t be comfortable for him. Not that you’d know that by the sight of him. He’s looking at Regulus the way a cat might look at a cornered rat. Calm, and in control. “’Course not,” Regulus huffs, and takes off his own clothes, which take longer. He even has an undershirt. Mum’s perfect little angel,Sirius thinks sarcastically. Remus has that same serene smile on his face that he gets whenever his mind’s wandering off. When Regulus is finally down to his pants, Remus makes a move as if to get on the bed, but decides against it. Instead, he cups Regulus’ jaw, and kisses him. It’s a chaste kiss, but it makes Sirius hold the arms of the armchair so tight that he’s sure his knuckles must be white with the pressure. The short kiss is over swiftly, thank Merlin, and Remus leads Regulus onto the bed. As Sirius’ little brother settles down, Remus shoots a quick glance at the empty-looking armchair. Not asking permission, really, but reminding Sirius that he knows that he’s there. Sirius is positioned perfectly in the room - or maybe the bed is. Either way, the important thing is that he can see everything. Remus takes his time taking his brother’s clothes off, touching and massaging Regulus slowly as he goes. They’re both silent, which seems odd to Sirius. He and Remus always talk or at least make more noise than just breathing.Sirius feels cheated, as if he’s not experiencing it in full. Yes, he can see Remus kiss Regulus’ jaw and rut against him but… It’s just not complete. It feels hollow, sort of. What’s missing doesn’t become clear until Remus utters, breathlessly: “Yeah, that feels good” into Regulus’ neck as the dark-haired boy starts wanking Remus off. He needs them to talk. Unfortunately, he can’t communicate this to Remus, and the next five minutes are more of the same, quiet sex. Remus and Regulus are wanking each other off, and fuck yes it does look hot but it’s just not hitting the right spot, it’s not— “Want to fuck you,” Regulus growls, thrusting up into Remus’ hand in a way that makes it clear that he won’t last long at all, let alone long enough to fuck anyone. But he’d like to. To fuck what belongs to Sirius. Sirius’ cock twitches and pushes against his boxers uncomfortably. Remus bites and sucks on Regulus’ shoulder, suckling on it as if he has all the time in the world, and they’re playing a game, not having sex. But his voice is shaking a little when he talks from the exertion, giving his real state away. “Next time,” he promises, and isn’t that the best of promises? “You’d do that, to him?” Regulus says, eyes shut closed, left hand groping helplessly at Remus’ back. Sirius can almost hear him say ‘so close, so close’. “None of his business.” Sirius wonders if he can come without touching himself. He doesn’t get to find out, because Regulus comes, and Remus takes over on his own cock, quickly making himself come as well. Sirius can only see a bit of it, but he’s sure Regulus’ whole stomach is covered in come. He shudders at the thought. He doesn’t know what’s hotter. That Remus has used Regulus, or that Remus uses Sirius, gets pleasure from wherever. Sirius isn’t special at all, and Merlin and Circe that thought is so incredibly hot that he feels like throwing off the cloak and telling Regulus to get lost because he hasto wank right now he hasto come. Thankfully, Regulus doesn’t take long to catch his breath and cast the cleaning spells. “Same time next week, then?” he jokes, putting on his undershirt. “We’ll see,” Remus replies cryptically, with a lopsided grin. He’s lying on the bed now, propped up on his elbows. To Regulus it needs to seem as if Remus will call him if he damn well feels like it, but Sirius knows deep down that Remus will ask what Sirius thought of it, first. What Sirius thought of all this is incredibly clear because the click of the door closing hasn’t even stopped when Sirius throws off the cloak and jumps onto the bed, making a startled Remus laugh. “Hey,” Remus chuckles. “Hey yourself,” Sirius says, eyes half-lidded and voice low. He’s too randy to even pretend to be coy about this. He straddles Remus and stands up on his knees, pushing his robes and trousers away and pulling his cock out from his pants. He doesn’t care if his jeans are rubbing against his cock he needs to come now now now. Remus seems to cotton on, squeezing one of Sirius’ thighs, as he starts speaking while Sirius wanks on top of him. “Liked that, did you?” Sirius only grunts in response, looking at Remus to see any traces of come. Somebody else’s come. Regulus’ come.There’s so much precome on his cock now that, as his hand moves, every downward thrust sounds like slapping water. “Me and Regulus? Or is it me and anybody that you like?” Remus teases, voice husky. “Love that I’ll have anyone, and all you can do is watch?” Sirius whines, nodding, and tries to keep his eyes open. “Good that you know that,” Remus says, and Sirius’ eyebrows furrow in confusion before he elaborates. “That I’ll fuck anyone, not just you. Have a thing for dark hair and high cheekbones though, so good thing Reggie’s around. And he’s so very willing to be used, just like his brother.” Sirius leans down now, putting half of his weight on his right arm, kissing Remus’ chest, which is the only spot his mouth can reach. “Why should I settle for one, when I can have both?” Remus continues, and Sirius can’t see his face anymore but can hear the mocking smile on his face. “Or maybe I should just trade you in. Keep Regulus. He’s younger. More willing to please. No backtalk.” “I’ll— I’ll be good,” Sirius groans, hand tight on his cock. Almost there. Almost. Almost. “I don’t know, Sirius,” Remus sighs. “You’ve been trying, but it’s just not enough. His cock was bigger, too. Bet it’d feel better than yours ever did.” Sirius comes so hard he hits Remus on the chest with his head with enough strength to make Remus cry out “ow!” in pain.   ===============================================================================   Before the second rendezvous is set, Sirius asks Remus, as openly as he can, about something like this, to take it up a notch. “You should… Should talk more.” Sirius is scratching his stubble, all pretend casualty, as Remus glances at the clock. “Talk more?” “While you two— You know—” Sirius gestures with his hands, making Remus chuckle. “What do you want me to say?” he asks with such fake-honest openness that Sirius glares. “Well, you need to tell me,” Remus insists. “What you say when it’s us two,” Sirius says slowly, as if each word is painful to get out. “That I want to shag Regulus?” Remus asks, eyes wide with the same insincere honesty. Sirius doesn’t deign him with a response, but does watch with interest as Remus walks over to him with slow, sure steps. “That his cock’s bigger than yours? That I’m done playing with you, I’ll play with him from now on?” By the end of the last question, his voice is somewhere between a growl and a hiss. He’s looking at Sirius with lust, and a dash of challenge. “That what you want to hear, Sirius? That your little brother’s better than you?” Sirius doesn’t answer, but he doesn’t have to. He’d gone down to his boxers this time, and there’s a big wet spot right in the middle. Remus glances down and laughs evilly. “I thought so,” he huffs condescendingly, and looks at the clock again. “Almost time,” he says, voice back to its normal tone, “Go on. The cloak.” Sirius, who hates orders, obeys without question. He reaches for the cloak to put it over himself when Remus stops him. “On second thought, hold on.” Remus worries his bottom lip for a few seconds. “Maybe this time you’ll need a little help. If we’ll do what you want.” The animagus nods, unquestioning. Remus is in charge now. “Come sit on the edge,” Remus instructs, nudging the chair with his right knee. Sirius complies, and as soon as his feet touch the ground, Remus drops to his knees. He runs his hands over Sirius’ thighs for a few moments before looking up. There’s the soft beginnings of a flush across Remus’ cheeks, and his lips are parted a little. Gorgeous,Sirius thinks, as always, and his cock pulses in agreement. He might have his weird fantasies about Remus wanting other people, but that doesn’t mean he doesn’t love seeing Remus on his knees. He’s thinking about how complicated his queer fantasies are, when he feels something against his left ankle. “Wh—” he starts, then looks down. Remus is tying his leg to the chair with what looks like a belt, but it’s coming out of the chair itself, and is the exact length to tie an ankle up. “Oh,” he lets out, breathless. Remus looks down and ties both his ankles to the chair quietly. He tests the bounds a little with one finger, then sits back on his feet, and looks at Sirius. “I’ll need your wand,” he says casually. Sirius hands it to him without a word. He feels powerless as soon as he - reluctantly - lets Remus take his wand. His body feels conflicted about this new development; part of him wants to grab the wand back, and the other part of him - mostly his prick - wants this to never end. “I’ll need to tie your hands too, of course,” Remus continues, then gently tugs at Sirius’ arms until they’re behind him. Sirius can’t see, but he feels a similar leather to the one touching his ankles wrap around his wrists. He doesn’t have time to wonder, or ask Remus about it, because Remus quickly pours the cloak over him and turns around, just in time to greet Regulus. “Hello, Regulus,” Remus says cheerfully, all casual politeness and smiles. “Lupin,” Regulus says with a nod. “Come now,” Remus chuckles, walking towards Regulus, then leading him by the hand to the bed. “You can call me Remus by now, surely.” “Mm,” Regulus hums in disagreement. Whatever his thoughts are on the subject, he doesn’t reveal them. Soon, it doesn’t matter, because they’re both naked on the bed. This time Remus is on his back, with his legs spread wide to accommodate - to welcome- Regulus in between them. Regulus leans over to reach his trousers, but Remus holds his arm. “What is it?” Remus asks, with all the innocence of a student revising in the library on a quiet Sunday afternoon, not one about to fuck another - barely- legal - student. “Lubrication, Lupin. Surely you’ve heard of it? Don’t try and pretend you and my brother have never…” Remus grins devilishly, giving both Sirius and Regulus pause. “Oh, don’t worry,” Remus says lightly, “Your dear brother has taken care of that.” “He has?” Regulus asks, not understanding. “Yeah,” Remus says, and pulls Regulus’ arm back onto his chest. “He’s prepared me. Sucked my cock dry while fingering me.” What? Thank Merlin he was too stunned to say anything out loud, because they haven’t cast any silencing charms this time. What’s Remus talking about? “What?” Regulus gasps, echoing Sirius’ thoughts. “Just a little while ago, he sucked on this cock that he loves so much, and opened me up wide.” Fuck,Sirius thinks. We should’ve done that.Although just hearing about is hot enough right now. “You mean— He—” Regulus stutters, arching back. He looks both aroused and confused. “You and he’ve just…” Remus blinks up at him a few times, feigning confusion to mirror Regulus’, then pretend-comprehension dawns on his face. “Oh, you mean… No, no.” He chuckles. “I didn’t let him fuck me. Just suck me off.” Regulus looks as if Christmas and his birthday have both come at once. “Yeah?” he asks, smiling slyly. “No, I don’t let him fuck me anymore,” Remus explains, then leans up for a quick nibble of Regulus’ neck, pulling the other boy down at the same time to get to his target. “I’ve moved on.” “Fuck,” Regulus breathes out, then puts a hand between Remus’ legs. Sirius can’t see it all from his point of view, but he can guess where Regulus’ fingers are prodding. Regulus gasps, loudly. “You really— Fuck, Lupin…” He laughs, incredulously, down at Remus. “I knew you had to be twisted to be friends with Sirius, but…” “Go on,” Remus urges him on, sounding bored. “Get to it.” Regulus, happy to comply, raises Remus’ legs by the knees, and positions his cock at his crack. “Ready?” he asks, and Remus sighs, frustrated. Regulus’ expression becomes annoyed, and determined, and he pushes forward with more force than he probably needed to, leading his cock with his right hand at the same time. “Mmmm, that’s good,” Remus praises him. “More.” Regulus’ motions are still cautious and slow, until Remus’ eyes snap open, and he demands: “Fuck me like you mean it, Black, unless I’m wasting my time again. Don’t make me lose hope in your whole family, now.” Grunting, Regulus pulls one of Remus’ legs from his ass cheek to get leverage, and pushes in further and further, until he’s buried balls-deep. Both boys sigh in contentment after that, and stay still for a few moments. Sirius thinks he might die on the spot. Or has he already died? “Yeah, that’s it,” Remus breathes, and Regulus starts rocking. “So big. Feels so good.” If Regulus is confused by Remus’ newfound chattiness, he doesn’t comment. He seems too lost in the sensations to comment, and Sirius can’t blame him. He can almost feel Remus, wrapped tight and warm around his cock. In a way he won’t let you anymore,his mind supplies, He has Regulus for that now. I won’t get to fuck him. Only serve him, and suck him off, nothing more.A groan almost escapes his mouth, but he stifles it just in time. Regulus has got into a rhythm now, and from the looks of it, is hitting the right spot, because the look of pleasure on Remus’ face is no longer faked. Sirius has seen Remus in ecstasy too many times not to recognize it. His stomach twists into a knot as his unattended cock bounces in excitement. It’s the perfect mixture of mental anguish and desire. He’s getting exactly what he wanted. It goes on for almost ten minutes, and Sirius feels as though he’s in a daze, staring at Regulus’ and Remus’ bodies moving in tandem, sweating and kissing and moaning. Remus’ uttered humiliating phrases are making him go crazy. Every now and again, the werewolf will let out something along the lines of “So much better than Sirius” or “Fuck yes, he’s never hit that spot before, you’re so good.” It’s odd to hear Remus singing praises of somebody else, especially in this context, but Sirius knows that it’s all about him, really, in the end. This time, to come, he doesn’t even need Remus’ verbal encouragement. Once Regulus leaves, and Remus puts his mouth around Sirius’ cock, Sirius is gone. Even Remus seems surprised at how quickly Sirius comes down his throat, coughing a bit as some of it goes down the wrong pipe. “Merlin, Sirius…” he chuckles, after. “Guess I know what to do next time.”   ===============================================================================   The next time doesn’t come around for almost three weeks, and Sirius is about to lose his mind. Before, it had been easy to ignore Remus’ glances at Regulus, or the parchments sent his younger brother’s way during class, every now and again. Because Remus had been setting things up, readying Regulus for their games. But now that it’s been weeks since they’d last been in the Room of Requirement, and the notes and looks haven’t stopped, Sirius is getting irritated. Absences he’d thought nothing of before start feeling like they might mean something. Every time Remus is not with him, he wonders if he’s with Regulus, if they’re having secret assignations when Sirius is at Quidditch practice, or not around for whatever reason. Thankfully, before his patience runs out and his jealousy rises to the level where he puts a stop to the whole affair altogether, Remus tells him that he’s arranged another meeting. “Saturday,” he says casually to Sirius, as he enters the dormitory. They’ve been together - as friends and partners - too long for Sirius not to immediately grasp his meaning. “In two days, then?” “Yes, Padfoot, indeed,” Remus says, smiling through his sarcastic comment, and moves closer to Sirius until they’re close enough to kiss. “Wanna practice?” Sirius throws him over the bed, and Remus lets out a yelp of surprise. “Wanker!” he calls out, laughing as they both settle under the sheets. They share a short but wet kiss, and Remus’ hands are already well on their way between Sirius’ ass cheeks by the time they stop. “Off,” he instructs, pushing Sirius’ pants away with the hand that’s already in them. “Demanding wolf,” Sirius responds, but complies. And when Remus’ body is flush against Sirius’, his cock buried deep within, Remus rewards Sirius’ compliance in spades. “You feel almost as good as Regulus,” he hisses, pounding into him, and Sirius barely gets three strokes in before he’s spilling all over Remus’ sheets.   ===============================================================================   Despite Remus’ claims of them practicing for tonight by Remus being on top, the werewolf is about to let Regulus fuck him again, and Sirius finds himself grateful. Not that he doesn’t love the thought of Remus fucking Regulus - because he does - but something about the way they’re doing it now feels better. Regulus has Remus on the bed, on his stomach, and with his legs spread wide. He’s massaging Remus’ ass cheeks and licking his balls. He’d tried to do more - to lick Remus there- but Remus had stopped him. On one hand, it had felt good that Remus had respected Sirius’ wishes to not try new things with Regulus. On the other hand, Sirius would’ve loved to have seen that. Both because it was such a debauched act, and because Remus going rogue was a deadly sexy thought all on its own. “Such a talented mouth,” Remus gasps out. From Regulus’ head movements Sirius guesses that Regulus has just sucked a ball in and let it go slowly, but it’s tough to tell. He can’t bloody seeanything, which is getting really frustrating in more ways than one. Soon, it becomes less of an issue, because Regulus moves on to preparing Remus with his long fingers that, as Remus has mentioned many times, resemble Sirius’ own. “More than my brother’s?” Regulus asks, chuckling smugly. “Mmm,” Remus agrees. “I’m here, aren’t I?” “You are,” Regulus says, and the look he gives the back of Remus’ head is too smug for Sirius’ liking. Sirius’ cock’s opinion is the polar opposite of Sirius’ own, and it pulses, letting some precome out. When Regulus starts sliding two fingers easily in and out of Remus, the werewolf murmurs something that Sirius can’t hear, because he’d been too lost staring at Regulus dark hair moving against Remus’ skin, bobbing up and down. “Ok,” Regulus answers, voice husky, and sits up on his knees. He puts his hands back on Remus’ ass, and spreads his cheeks. He lets out a pleased sound, and Sirius bites his lip to stop himself from doing the same. Not having the silencing charm is making him have to control himself which is hot, but at the same time excruciating. Then again, that’s why it’s hot. Remus turns his head to the side to speak, eyes half-closed in pleasure, panting lightly. “Not here,” he says. “What d’you mean?” Regulus asks, frowning, and doesn’t let go of Remus’ ass. “Floor,” Remus pants, pulling his legs in to get up. Regulus watches him get up, looking after him, puzzled. Remus is still breathing heavily, but his posture is calm and composed as he walks over to the corner, almost touching Sirius. Then he drops to his hands and knees, right in front of the armchair Sirius is sitting invisibly on. They’re so close that as Remus turns his head around the gesture for Regulus to come over, his hair tickles Sirius’ leg. Oh fuck,Sirius thinks, eyes widening. I’m going to come on Jamie’s cloak. Because really, he can’t see how he won’t. Not when Remus is so close. Not when Remus’ face is flushed, lips swollen and parted, and Regulus is settling in to— Fuck fuck fuck,Sirius thinks again, and tries to calm down his breathing to not make too much noise. He can’t move either, despite his erection getting really uncomfortable, because Regulus will surely hear. They’re so close. “Fuck me,” Remus says quietly, half-demand, half-plea. Regulus promptly positions himself behind Remus, and pauses just as he’s about to go in. “How long has it been?” Remus gives him a look before turning back towards the armchair. “We met… Three weeks ago, right?” Regulus swallows visibly, and closes his eyes for a few seconds. When he opens them back up, his whole face is painted with hunger and satisfaction. “You haven’t let him…?” Remus huffs. “‘Course not. I told you, he doesn’t get to fuck me anymore. He’s had his chance, and didn’t measure up.” It seems enough of an explanation for Regulus, who doesn’t prod further. It almost seems as if Regulus needs to know that Sirius is powerless, that Sirius’ beloved boyfriend is being taken away from him by force, the same way that Sirius does. As Regulus pushes in - slowly, but none too gently, from the looks of it - Remus throws his head back and lets his jaw drop. His eyes are half-open, and glazed over. Sirius watches Remus’ wanton face for a few moments before lowering his gaze to see the action. Regulus has one hand spread across Remus’ back, scratching it lightly, and the other hand is holding Remus’ hip steady as Regulus thrusts in again and again. Sirius almost feels proud at how steady and (from the sounds Remus is making) enjoyably rough Regulus’ strokes are. The pride part of it is ruined by the fact that his little brother’s fucking his boyfriend, though. Well, ‘ruined’ might not be the word for it. ‘Elevated’, perhaps. Oblivious to Sirius’ inner musings about his younger brother’s betrayal, Regulus angles himself to try and find the perfect spot, and doesn’t stop rearranging his legs until Remus lets out a loud “Ah yes!” After that, Regulus starts rutting with newfound energy and Remus is completely gone, if his expression’s anything to go by. Sirius doesn’t know where to look. Watching Regulus slide in and out is mesmerizing, but so is Remus’ flushed face, lost in lust and pleasure. Remus is blushing even more now than ever before, though Sirius isn’t sure why. He’s red down to his chest. When Regulus’ rhythm finally starts to stutter, Sirius looks down to see— Yes, Regulus is stroking Remus now. It looks too rough to be enjoyable without any lube or even precome, but Remus doesn’t seem to mind, and keeps moaning out incoherent sentences. “Fu— Reg— Yes— Mmh! All I need— Aah—!” Sirius is trying to commit all this to memory as best he can, and making plans to immediately make a Pensieve memory out of this encounter, the second Regulus walks out the door, when Remus looks at him. Well, not exactly at his eyes, Remus’ stare is falling a bit more towards Sirius’ chest, but Sirius gets the idea. His heart skips a beat and he forgets what he was trying to do. Remus keeps looking at him as Regulus’ thrusts rock him back and forth. “Take it off,” Remus breathes out. Sirius stops breathing, as if that could make him disappear completely. “Take it off, Sirius,” Remus repeats. Sirius’ head snaps up, and he looks to see Regulus’ reaction. Regulus doesn’t even pause. If anything, he starts thrusting with more force. Slowly, a lecherous grin spreads across his face, and now Regulus is looking at the armchair as well. A thousand thoughts go through Sirius’ head, and he can’t decide which is worse. Regulus knows.He’s maybe known for a while. There isn’t even a smidgen of surprise in his eyes. Sirius Black is rarely truly speechless, rarely rendered immobile, but here he is, frozen, embarrassed, and fuck,turned on beyond belief. His cock hurts. Regulus knows that Sirius is there. That Sirius and Remus are still together and that Sirius has known, all this time, just how Regulus has been using Remus. “Don’t— Ah! Don’t make me get up,” Remus chides. Sirius still doesn’t move, not until Remus speaks again. “I really want a cock in my mouth.” Remus whines. “Please,” he gasps out, still rocking like a rag doll as Regulus’ cock pushes him back and forth. If there was ever any fight in Sirius to not join this - twisted, perverted, he’s yourbrother - it leaves him. He throws off the cloak and Remus clamps Sirius’ right ankle as soon as he can see it. Remus moves his head forward, mouth wide open and tongue lolling out, but he can’t reach Sirius’ cock. He looks at Sirius’ cock as if it’s all that matters. The fact that it’s attached to Sirius is irrelevant. Remus just needs more cock, and Sirius happens to have one. Just thinking about that is keeping Sirius occupied, and he doesn’t make a move to try and put his cock in Remus’ mouth right away. “Go on then,” Regulus chuckles, breathless. “Do I need to take care of that, too? Bring another friend along?” Sirius’ head snaps up, and he stares at Regulus, aghast. He can’t believe little, shy Regulus is talking like this to anyone, let alone Sirius. “I don’t have any other dark-haired friends - and your friend here is clearly partial to it - but at this point…” Regulus looks down at Remus and laughs. Actually laughs.“I think any cock would do, don’t you?” Remus is slobbering at this point, and keeps trying to stretch his neck to get to Sirius’ cock. “No wonder he ended up with you,” Regulus muses, sounding as matter-of-fact as he can, fucking Remus relentlessly and panting with exertion. “The closest cock he could get to, what with Potter and Pettigrew not being available.” Suddenly Sirius sees flashes of James or Peter doing this with Remus, and he inches forward, needing to feel Remus’ lips on his cock. “There you go,” Regulus praises him, and Sirius would punch his mouth if he didn’t have muchmore immediate concerns. He’s embarrassed and the third person being his brother is making everything worse and so much better. When his cock finally slides into Remus’ mouth, Regulus hisses and starts short, jerky thrusts instead of his earlier steady ones. “Yeah, go ahead. Give him what he needs,” he says. “While you still can. You know he’ll find someone else, soon as you leave Hogwarts.” Sirius stares up at his little brother again, eyes wide. “He’s just using you. Same as he’s using me. Why do you think he chose me?The most perverted person you could be in bed with?” Sirius wants to point out that they’re not in a bed but his mouth isn’t working at all and fuck, how is Regulus so eloquent throughout all this? “Though I have to admit,” Regulus says softly, leaning over Remus now, so that Sirius can’t see his face. “I love filling him with my come, knowing he used to be yours.” Remus continues suck and licking Sirius’ cock, going at it with all the enthusiasm of a dehydrated traveler finding water at last. His mouth keeps sucking Sirius in, and his tongue never stops moving, sliding across the bottom of Sirius’ cock. It feels like heaven. After a few seconds of catching his breath, Regulus shuffles back, and gives Remus’ ass a single - but hard - slap. Then he spreads Remus’ ass cheeks, and looks at Remus’ hole appreciatively. “Fucking brilliant.” He lazily tilts his head up until he’s looking into Sirius’ eyes. “I think you’ll have some cleaning up to do, after. Heard that’s all he lets you do now. Clean up, after.” As if on cue - or maybe because he can feel Sirius’ cock get even harder - Remus takes his head back a little, and keeps sucking half of Sirius’ cock, while working the bottom half with his hand. Quick, efficient strokes that leave Sirius completely incoherent. It feels like he’s coming forever, as he clutches Remus’ hair and twitches again and again, filling Remus’ mouth. After he comes, he lets his head drop to the side, eyes closed, body covered in sweat, and doesn’t move. Remus lets go of his spent cock, and puts his head on Sirius’ thigh. Only then does Sirius think about the fact that yeah, Remus probably hasn’t got off yet, what with his hand being too busy to bring himself off, and that lazy tit of a brother of his hasn’t bothered to finish the job he started. Remus lets out a groan, and Sirius opens his eyes at the sound. Remus’ debauched face - lips puffed, panting like a dog, eyes glazed over with pleasure - is rubbing against Sirius’ thigh as Remus’ arm moves. He’s just been fucked thoroughly by Regulus, and has Sirius’ come in his mouth and stomach. He’s gotten all the Black brothers can give him. Sirius thinks about getting up to help, but Remus apparently doesn’t need it, because with another soft grunt and a twitch of the face, Remus is spilling all over the floor. As Remus catches his breath, Sirius watches his gorgeous body heave and relax, then lets his eyes fall closed again. He feels sticky, and he definitely needs a shower. Remus will, too. Sirius feels Remus move away and get up, but keeps his eyes firmly closed. He knows that soon he’ll have to open his eyes again, and face what they’ve just done in this room, and talk. It could go horribly, with Regulus making fun of him and ending up with broken - or non-existent - bones, or it could go well and Regulus could ask to do this again. Little Reggie has definitely given a good enough performance to earn an encore. Sirius hears some rustling of fabric, then some whispers that he can’t make out. For now, Sirius lets his body slouch, and his mind stay mostly blissful, enjoying the afterglow. Until he opens his eyes, he can keep enjoying this.   Maybe even after.     [threesomecol.png] Please drop_by_the_archive_and_comment to let the author know if you enjoyed their work!
