Summary
     The first time Sirius notices Regulus look the Marauders’ way and let
     his eyes linger, Sirius doesn’t think anything of it.
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.
