Work Text:
Of course, Ominis knew of Sirius Black. He was Slytherin’s Seeker, and the team’s captain. He was dreamy, said Imelda, and he was spoiled rotten, said Anne. He was the headmaster’s son.
He didn’t know Sirius Black. Sirius was two years younger, and exactly the type of Slytherin Ominis swore he’d never be. Gliding through the castle on feet lightened by bigoted superiority and ill-gained gold. Ominis hated the slick, charming voice he used whenever he spoke to the professors, like the day he waltzed into NEWT History class, despite being a fifth year, and asked Professor Binns for admittance to the Restricted Section.
“Binns?” Sebastian complained as they exited into the corridors after yet another tedious ghost lecture. “Why didn’t I ever think of that?”
“You enjoy sneaking around too much,” Ominis said. “The power. The thrill.”
“I’ll show you power and thrill,” Sebastian muttered, but as they were surrounded by students in a public space, he was unable to.
Ominis had entirely forgotten the conversation by the time Sebastian made good on his promise.
When it happened, Ominis was stretched out across his bed, comfy in his navy-striped pyjamas. He laid belly-down, head propped up on both hands as he listened to his notes from the Charms lecture the day before, when he felt a heavy weight against the whole of his back.
He barely managed to hiss in surprise before a warm, familiar mouth found the side of his neck. It traced its way from the corner of his jaw down to his collarbone, sliding deeper as Ominis leaned over to allow further access.
“Thrill,” Sebastian said into the bit of Ominis’ chest he could touch. Then he drew back, climbing onto the bed, settling with a leg on either side of Ominis’ hips, and pulled on the bed’s curtains. As they rustled to a close, Sebastian rolled his hips, rubbing his cock against Ominis’ ass. Ominis thrust his own hips back, meeting Sebastian’s erection with firm flesh.
“Is this still a thrill?” Ominis whispered, twisting his head further to the side so his words wouldn’t be muffled by his sheets. “How many times have we gotten off in this bed by now?”
“It’s always a thrill,” Sebastian said, the words a low growl from deep in his throat. Ominis felt a delicious shiver pass through him, working its way through his limbs and settling in the low of his belly. He thrust again, this time seeking friction for his own cock and finding it against his mattress. Sebastian curved a hand around Ominis’s shoulder and tucked it down the pyjama top, wiggling beneath their combined body weight until he could drag the heel of his palm across Ominis’ nipple.
Ominis gasped, but the sound was lost to Sebastian’s mouth as he kissed him. They both moved with increasing desperation, unheeding of the squeak of the mattress springs forged by each simultaneous grind.
It felt good—so good—Sebastian’s weight and touch was all Ominis would ever need—his hands and mouth, too, Merlin the things Sebastian could do with his mouth—
Ominis came with Sebastian’s hand on his chest, Sebastian’s lips open against his chin, Sebastian’s thighs clenched around Ominis’ hips. He cried out, and Sebastian’s weight fell fully on Ominis as he lifted the hand he’d been using to support himself and covered Ominis’ mouth with it.
“Be quiet,” he said, a little stern, mostly teasing. “And flip over.”
Ominis did as he was told—eagerly. He shifted, rolling slowly, allowing Sebastian time to adjust so he stayed up without toppling off the bed. Sebastian did not come as easily as Ominis, but Ominis was happy about that when it meant his hand on Sebastian’s cock.
“Stroke it,” Sebastian said, rolling his hips to rub his erection against Ominis’ palm. “Touch me, Ominis. You know how much I like it.”
He didn’t have to ask. Ominis did it because he loved it.
As he touched Sebastian, he trailed his other hand to Sebastian’s face, sliding over the smooth skin of his arm and the soft cloth of his shirt on the way up. He dragged his thumb along his lower lip, feeling the dry, slightly scratchy skin there before nudging deeper to the damp inside. The tip of his thumb bumped along Sebastian’s teeth, and Sebastian’s tongue lifted to swirl along the thumb pad, prickling goosebumps along Ominis’ forearm and sending a zap straight to his softened cock.
Ominis whined, a half-formed thought about unfairness flickering through his mind. He lost the thought entirely when Sebastian sucked, dragging his thumb down along his tongue.
All the while, Ominis’ other hand never stilled, holding Sebastian with practised firmness as he stroked.
Sebastian said something around Ominis’s thumb, but Ominis couldn’t make it out, and then a moment later something flicked across Ominis’ wrist. It landed warm, though cooled quickly in the dank air.
“You came for me,” Ominis said. Sebastian bit down on his thumb before pushing it out with his tongue.
“I came for me. And please explain how you are hard again already.”
Ominis wiggled his pyjama clad hips, pressing up into Sebastian’s weight, and said, hopefully, “I just showered.”
“Fine,” Sebastian said, pretending to be reluctant, though they both knew how much he loved sucking Ominis’ cock. “Clean yourself up first, though.”
That, too, Ominis didn’t need to be told. He licked his wrist clean eagerly, and by the time he dragged his sleeve across his mouth, drying it, his pyjama bottoms were pulled down, and Sebastian’s tongue was licking along the underside of his shaft.
Ominis arched up his hips at the pleasure, and whimpered when Sebastian tugged the head into his mouth. He’d come recently enough that the soft warmth of Sebastian’s mouth was nearly too much.
Sebastian knew it. He tongued slowly and carefully along Ominis’ cock, dragging the pleasure out of him unhurriedly, as if time was not passing outside their four-poster bed. As if a dormmate might not walk in at any moment. As if there was nothing else in the world he’d rather be doing than bringing Ominis to his second, gut-wrenching orgasm of the evening.
“I fucking love you,” Sebastian said when he was done, laying his body beside Ominis’. The bed was not made for two, and still they squeezed into it, a tangle of loose limbs and warmed flesh.
“Love you too,” Ominis mumbled. “But you didn’t live up to your promise. This was only thrill, no power.”
“Of course,” Sebastian said, petting the top of Ominis’s head. His hand felt steady and confident in its movements. “This was only part one.”
Ominis was half-asleep, and in the post-orgasm state of not caring much about sex anymore. He rubbed the soles of his feet against Sebastian’s calves, enjoying the soothing tickle of hair against smooth skin, and promptly forgot about the whole part one and two business, as he did the conversation when it originally occurred.
It wasn’t that Ominis had a bad memory. It was that he had so many memories with Sebastian, and for the two years since they got past the whole…unpleasant business of fifth year, their moments together had been mostly happy. Blissfully so, at times. Especially when the moments occurred within the hanging curtains of their beds.
There were other places, too, that held warm memories. The Sallow cabin in Feldcroft, the Undercroft, the back of the Groundskeeper’s hut, the tower by the thestral barn along the Hogwarts boundary…
They’d touched each other in nearly every way, in nearly every place, except—
“The library,” Sebastian whispered the next morning, nuzzling his forehead into Ominis’ hairline. “Can you meet me there tonight? Around ten?”
“After hours?” Ominis complained, even as his hand slid out and found Sebastian’s thigh, cupping it high enough that his knuckles brushed the seam of Sebastian’s trousers. “We only have three more months before we graduate, could you please manage ninety days without getting us both dragged into detention?”
Sebastian slid his head down along the side of Ominis’ face, pressed kisses along his jawline, and found his ear with his mouth.
“You didn’t complain last time,” Sebastian whispered, before biting gently down on the rim of his ear.
“Boys!” Professor Weasley’s outraged voice slapped across Ominis’ ears, instantly chilling all the warmth flooding his body from Sebastian’s attention. He gave Sebastian’s thigh a squeeze and then disentangled, scooting further along the bench to make some space between them, despite his strong desire to shift the opposite way and climb onto Sebastian’s lap. He’d grind down on his cock, and Sebastian’s hand would go around his hip to grab him—
“What on earth do you think you're doing?” Professor Weasley demanded, closer now, by the sound of it.
“Our apologies,” Sebastian said, light and innocent, as if his tainted reputation wasn’t well-spread around the school. The articles in the Daily Prophet for the entirety of their sixth year hadn’t helped. “Ominis got carried away. He thought we were alone, since he can’t see anyone else in the hall—”
“Shut up,” Ominis hissed. Now, when his ears burned, it was not out of desire for Sebastian’s touch. “Professor Weasley, I sincerely do apologise, and please forgive Sebastian, you know how he is.”
“Unfortunately,” Professor Weasley said, “I do. And you, Mr Gaunt, should be well aware that Mr Sallowis is under close watch from all staff as part of his plea to the Wizengamot. If you’re truly his friend, you should be helping him find a better path.”
“Yes, ma’am,” Ominis said, sounding carefully subdued.
As soon as Professor Weasley left, signified by the rustle of her robes and the soft clack of her heeled boots along the stone floors, Ominis grabbed Sebastian by the upper arm.
“Why did you have to say that? Do you think the idea that you could get sent to Azkaban at the snap of a professor’s fingers is funny?”
“Weasley isn’t going to send me to Azkaban,” Sebastian said, though the confidence in his voice sounded more like bravado. “But if you’re so worried about it, maybe you shouldn’t be touching me.”
Ominis threw Sebastian’s arm from him as quickly as he’d reached for it, and moved further along the bench. He bumped into something of medium firmness, which squeaked.
“Sorry!” said a tiny little voice, and then the pressure beside Ominis was gone.
“Look at Mr High and Mighty,” Sebastian said. “Mowing down first years.”
Ominis pulled out his wand as he stood from the bench, and turned his back resolutely on Sebastian as he navigated his way out of the hall.
He had about ten minutes to himself, walking through the corridors and down into the dungeons for NEWT Potions. He’d just assembled his ingredients for the day around his cauldron when he heard the thump of a body dropping into the seat beside him.
“You can be mad at me,” Sebastian said, “but come tonight. Please?”
Ominis was mad at Sebastian. But he was also in love with him, and Sebastian had never mastered the concept of leaving well enough alone. He spent all of Potions sneaking little touches: tracing Ominis’ wrist, sliding his fingertips along Ominis’ forearm, taking his hand and kissing each of his knuckles.
“Fine,” Ominis said grumpily, as they finished packing at the end of the lesson. “I’ll meet you.”
He couldn’t see Sebastian’s grin, but he was fairly sure it was there, especially once Sebastian slid their hands together as they exited the classroom.
They stayed together the whole day, as was their norm, though Ominis was very careful to avoid touching Sebastian within the Great Hall for lunch or dinner. After dinner was when they normally spent (more) time together, strolling the grounds (to find a private spot to fuck) or (lazily fucking) in the Undercroft or studying in the common room (often interrupted by sneaking away to fuck).
But Sebastian chastely kissed the bridge of Ominis’ nose and said, “I’ll see you at ten!”
Then he was gone, and Ominis was left to kill several hours alone. He had mountains of coursework, but who felt like studying when a secret rendezvous with your boyfriend was only hours away? So instead Ominis went out to the grounds for a bit, and entertained himself by convincing a group of third years that he’d gone blind after making eye contact with a Basilisk through a mirror.
Then he headed to the library, and hunkered down beneath a desk to wait out the closing rounds.
The things he did for Sebastian.
By the time he crawled out from under the desk, his knees were stiff, and the top of his head was sore from pressing up against wood. He forgot sometimes how much he’d grown even since the start of the school year. There was a particular door on the third floor which his head would always bump into if he forgot to stoop.
“A door for goblins,” Sebastian said once, though Ominis never heard him hit the frame.
“Ominis!”
As Ominis shook out the cramp in his calf, he caught his name hissed from across the library, and turned in that direction. The Restricted Section, of course. Where else would Sebastian be?
“Please tell me why we’re here,” Ominis said as he stepped through the gate.
“You’ll see,” was all Sebastian would say, with sing-song satisfaction stretching his words.
“I have a terrible feeling about this.”
He actually didn’t. Sebastian being odd and secretive had led to some of the best sex of their lives. Like the time—
“Sebastian Sallow.”
Ominis, instinctively, reached for Sebastian’s hand. His palm grazed Sebastian’s sleeve, but Sebastian shook him off, or unknowingly moved away. Either way, the touch missed, and Ominis was left standing alone, gripping his wand too tightly. He could navigate around the Restricted Section by memory, not even needing his echolocation spell, but the presence of an unknown person made movement feel unsafe.
“Sirius Black,” Sebastian said, his tone as mockingly polite as Sirius’ had been.
“What a surprise to see you here,” Sirius drawled, in a way that did not make him sound surprised at all.
“Is it? I thought we said ten?”
“Oh. Done playing already?” Sirius’ voice went suddenly normal, not that of a snooty Pureblood but of any other student. It was deeper, a little rougher, and a lot more pleasant to listen to.
“Done playing? No, Black. The game hasn’t even begun.”
Sirius laughed—genuine amusement, with an edge of…excitement?
“What’s going on?” Ominis demanded. He hated that he sounded so reedy and scared, but that was exactly how he felt. Sebastian hadn’t told him they were meeting anyone else, let alone the headmaster’s son. This all seemed like a bad decision on the cusp of being made.
“Power,” Sebastian said, and finally he took Ominis’ hand, steadying him among the disquieting stillness.
“Power?” Ominis repeated. “Power like…” He didn’t finish the sentence. He was too busy blushing, recalling the context in which he and Sebastian had last discussed this. It wasn’t like he was a prude, considering how handsy they got with each other in public, but it felt different to melt among the crowds compared to here, with a private audience of one.
“Power,” Sirius said, and Ominis flinched. He hadn’t heard the footsteps, but Sirius had moved closer. His voice sounded near enough that Ominis could reach out and touch him, if he wished. “Gaunt, how many times did your family throw that word at you growing up? I know mine said it a dozen times a day. The power of a Pureblood family, the power of magic, power earned, and power bestowed at birth. My father tried so hard to instill in me a desire to wield power over others.”
“My father,” Ominis said, and then stopped. It felt so strange to speak of this with Sirius, when they’d never exchanged a word before. His family was an intimate and personal pain. Dredging them up was reopening the cut they’d slashed straight through his middle.
Sebastian squeezed his hand, and the silence was suddenly not oppressive but respectful. Sirius was…listening. He was waiting.
“My father spoke much the same. A bit more violently than yours, I’d imagine. He would never work at Hogwarts, or the Ministry. He has no interest in the systems that uphold the weak ruling class.”
Sirius laughed, and Ominis flushed. It was a shockingly pleasant sound, warm and mellow. No wonder Imelda and so many others had a crush on him. Ominis would like to hear him laugh again.
Except then he remembered Sebastian beside him, holding his hand, and Sebastian hours earlier, kissing his neck, and Sebastian the night before, swallowing his cock. He felt a surge of guilt and shame at being so suddenly taken with Sirius.
“Merlin, what an argument. I’d love to hear your father and mine debate. Although, no offense to Phineas, I’m pretty sure yours would spank mine soundly.”
The word spank in Sirius’ voice, and the sudden warmth of the room, and the restrictive feeling of Ominis’ tie around his throat—why had he not removed his tie after dinner?—became suddenly overwhelming.
“Sebastian,” Ominis said, trying to speak quietly, as though Sirius wasn’t right there. “I’m tired. Can we go now?”
“Of course, we can leave whenever you want,” Sebastian said, steady and reassuring. “Will you just listen to the last thing Black has to say?”
Ominis’ exhale felt thick in his throat, and his head felt twice as heavy as usual when he nodded.
“Ominis,” Sirius said, and he moved even closer, and then his fingers were on Ominis’ jaw, two of them tracing along the bone. “Here’s why Sebastian asked you to come here. My father tried so hard to impress a desire for power into me, and all he did was make me want to give it up. I want—I want—”
For the first time, Sirius showed some sort of weakness, even if Ominis couldn’t tell exactly what the weakness was. His words cut off, and his breath grew ragged, and his fingers kept on moving, touching softly on Ominis’ jaw—right in front Sebastian.
“He wants you,” Sebastian said, and Ominis jolted so hard his head snapped back, away from Sirius’ hand. He nearly ripped out of Sebastian’s grip, too, but Sebastian was holding on too tightly to allow that to happen. “He wants us. What do you want?”
“You’re saying…” Ominis felt his own chest heaving, his nostrils flaring. His hands were trembling, even the one curled inside Sebastian’s. “You’re saying you brought me here so we could have sex with Sirius Black.”
There was a long, dramatic pause.
And then Sirius did the worst thing possible. He laughed.
It was the worst thing, because it took Ominis’ breath away. He remembered just the feel of Sirius’ skin on his face, and he wanted more of it. He knew what Sebastian’s hands felt like on his body, and imagine Sebastian and Sirius, and—
“Here?” Ominis asked. “Now?”
“It’s Friday,” Sebastian said. “All the professors are at their monthly catch-up at The Three Broomsticks. Professor Black is here, but you know how useless he is—sorry.”
“Doesn’t bother me,” Sirius said. “He is useless.”
The strict tension of the room eased with each word spoken, but still it bubbled within Ominis’ gut. A million questions swirled through his mind, about the stupidity of this, about what it meant that Sebastian was even wanting to go along with this, if he even wanted to go along with it, if Sirius was tricking them, or if this was the worst thing they’d ever done together.
Then Sirius’ hand went back to Ominis’ face. This time he cupped with both hands, his palms firm against Ominis’ jaw, his fingers brushing the side of Ominis’ neck, where Sebastian had kissed just the night before.
“Well?” Sirius asked, his voice low and deep, so close that his breath brushed Ominis’ lips. “Shall we?”
Ominis’ mind did not know the answer, but his body did, and the yes came out of his mouth before he even realised he’d parted his lips.
“Don’t kiss him,” Sebastian cut in, and for a moment Ominis thought it had all been a test he’d failed. Then Sebastian said, “Let him kiss you.”
Sebastian took the hand he held, and brought it to Sirius’ hip; Ominis lifted the other on his own, and dragged Sirius closer until their pelvises fit together, and then he shifted forward until his lips brushed skin. It was smooth, slightly prickly skin—a bit of shaved face, not mouth. Ominis kept going, until he found the corner of Sirius’ mouth, and then, his grip tightening, he kissed Sirius properly.
Ominis didn’t think it would make much of a difference who kissed who, but it did. Sirius’ hands on his face became grasping—clinging. He was not holding Ominis in place to be touched, but holding himself, steadying himself against the onslaught of Ominis’ lips and tongue and teeth.
Sebastian came up behind Ominis, pressing as tightly against him as Ominis pressed against Sirius.
“Ominis sandwich,” Sebastian murmured into the back of Ominis’ neck.
Ominis laughed into Sirius’ mouth. He bumped his hips backwards, meaning it as a sort of nonverbal knock-it-off, but he rubbed against Sebastian’s cock, and as usual pretty much every meaningful thought fell from his brain.
“What should we do with him first?” Sebastian asked, lifting his head so his words could be clearly heard. “We could…tie him to a chair?”
“No.” Ominis drew back from the kiss, and released Sirius’ hips. “I’m going to touch Sirius, and you describe what I’m doing.”
Ominis didn’t know where his boldness came from. He didn’t care. It was what he wanted, and so he said it, and then after a moment his conscience surged up.
“If that’s okay with everyone,” he added quickly. Sirius’ laugh was more of a groan, and Sebastian smacked his ass with an open, firm palm.
“How about this? We’re not roleplaying, if someone doesn’t like something, they say no, and that’s that.”
“Fine,” Sirius said, sounding impatient. “Consent established, can we keep going?”
“Please,” Ominis said, and this time he found Sirius’ mouth with his hand. He brushed over Sirius’ lips, feeling the texture there, smoother and more even than Sebastian’s. He felt his jaw, a little narrower and sharper, and then paused. “Sebastian? Tell me everything. What does he look like? His hair, his mouth, his expression?”
“He’s handsome as fuck,” Sebastian said instantly, voice hoarse. Ominis resumed his touching. “He’s got these gorgeous fucking eyes, light blue—I know we’ve talked about colours before and they’re kind of useless, but the colour of—the sky after a storm, when the clouds are kind of clearing but everything’s still pretty grey.”
“You poet,” Ominis murmured. Sirius held himself still for the touching, leaning into it, like he enjoyed it. “What about his hair?”
“Not so different from yours, actually. Long, silky. I’m sure you can feel how soft it is. His is much darker though. Black, like his name, ha-ha.”
“Ha, okay. And this?”
“His—lips. They’re lips, I mean, they’re great, and you’re—I love when you do that to me, put your fingers in my mouth. Black’s loving it too. You should see his face, all prettily flushed and he can barely keep his eyes open.”
“Keep going,” Ominis said. “Follow my hands.” He slipped his fingers out of Sirius’ mouth, and kissed him instead, trailing the damp hand and the dry one down Sirius’ body.
“He’s wearing robes, the same robes as us. You can probably tell that. And you’re…touching his nipples through the robes. Move your right hand a little up, and—yes. You’re making circles, and now you’re rubbing them with your thumbs, and—one hand you’ve left on his nipple, the other is going down to—to his cock. You’re rubbing his cock through his robes, he’s fucking hard already—Fuck, Ominis, I—”
Sirius submitted to every touch. Not only did he accept it greedily, but he begged for more, pushing back against Ominis’ hands, crowding his body forward even though there was no space left between them. Behind Ominis, Sebastian kept up his stream of narration as he ground with increasing fervour into Ominis’ backside, his words stuttering out around pitched breaths which coiled around Ominis’ neck.
“Don’t stop,” Ominis said. In that moment he appreciated exactly the lesson on power Sebastian wanted to teach him. This was power, and the only kind of power he’d ever like to have, that which was freely given.
“You’re opening his robes, and taking his cock out. His cock is so hard in your hand. You’re stroking it, and every time you do I can see the head, all wet with precum because you’re turning Black on so much. I think he might come soon if you keep going, he keeps spasming in your hand, and his balls are drawn up, tight, and—where are you going?”
Ominis took his hand off Sirius’ cock, though he missed the warmth immediately. He didn’t feel any guilt at the frustrated groan that followed. He knew the brief loss of touch would be well worth it for Sirius.
“Sebastian,” Ominis said. “Should we suck his cock?”
“Yes,” Sebastian said immediately, coming around to Ominis’ side. Ominis felt a little thrill of pleasure on Sebastian’s behalf. He knew how much his boyfriend enjoyed having his mouth filled.
Ominis kept a hand on Sirius’s hip as he lowered to his knees, and then shuffled forward until he could comfortably nuzzle his face against Sirius’ hip, which he did before plastering hot kisses across the skin there, trailing down around his thigh.
A hand curled through Ominis’ hair—Sirius, he quickly realised, because the touch felt different from Sebastian’s, and because there was no force behind it, only an attempt to not buckle to his knees.
“Here,” Sebastian said, close beside Ominis. “Open your mouth.”
Ominis did. As much as he’d enjoyed bossing Sebastian around a little, he enjoyed this, too. Anticipation. His tongue darted out to rest along his lower lip, waiting, waiting…
Then there was the press of hard flesh against Ominis’ mouth, large and unyielding, so unlike a mouth, and surrounding the press of Sirius’ cock was the edge of Sebastian’s mouth, licking its way along the length.
Sirius, with his cock bobbing between two mouths, let out his first expletive, and then a string of swears, before finally descending into babbling. Despite his obvious pleasure, he stayed carefully still, never once thrusting with his hips or tightening his hold painfully in Ominis’ hair.
“Sirius is such a gentleman,” Ominis pulled back to say. Sebastian, unwilling to stop oral sex even for good banter, only hummed in agreement.
Ominis left Sebastian to it, enjoying the grunts and moans of Sirius coupled with the soft, slick sounds of a mouth moving over a cock. He pulled out his wand, slicked a finger with a spell Sebastian taught him, and reached around to slip between Sirius’ cheeks.
“Does this feel good?” Ominis asked, gently working one finger against Sirius’ entrance. It was then that Sirius finally seemed to lose control, grasping Ominis with a nearly-painful squeeze, thrusting so hard that his hips bumped into Ominis’ shoulder and Sebastian gagged.
“Sorry!” Sirius gasped at once, even as he pushed back against Ominis’s finger. “Fuck, sorry, it feels so fucking good—”
“I’m fine,” Sebastian said, and there was the sharp sound of flesh against flesh. Ominis felt Sirius’ ass jiggle, and realised Sebastian had smacked it. “You like Ominis touching you there?”
“Yes,” he said at once. “I like everything you two have done.”
“Thought so,” Sebastian said, sounding pleased. “Ominis, go on, I want to see.”
“Well, if you want a show…”
A moment later, Sirius laid over one of the tables in the Restricted Section, his legs spread, his ass pushed up by the worktop’s edge. Sebastian stood beside him, twisting his shoulders down to stroke Sirius while keeping his head lifted to watch Ominis work. This was what Sebastian narrated to Ominis, as Ominis refreshed the lube on his fingers and felt along Sirius’ puckered flesh.
He didn’t know Sirius, but he knew he was only a fifth year, and that whatever confidence he displayed normally had been quickly cast aside during the whole encounter. So Ominis moved carefully, slowly, giving Sirius all the time he needed to adjust, first to Ominis’ finger nudging its way inside, and then to the fullness of a finger slid in to the third knuckle.
“He’s going to come,” Sebastian said, as Ominis gave a little wiggle of the fully-buried finger. “He loves you fingering his ass so much, he’s going to come right now, he’s coming—”
Sirius announced it on his own with his loudest grunt yet, followed by a low, heavy moan, and he clenched around Ominis’ finger in the same moment his hips jerked forward,l. Sebastian let out an appreciative sigh.
“He looks so beautiful and soft like this, Ominis. Like he needs someone to wrap him up in a blanket and tuck him in.”
Sirius laughed at that, though the sound was quickly cut short at Sebastian’s next words.
“You should come clean him up.”
Ominis slid his finger carefully out of Ominis, spelled his hand clean, and dropped to his hands and knees to do just that. He crawled between Sirius’ spread legs, low to the floor to avoid bumping any sensitive parts, and then he turned around and found Sirius’ spent cock with his hands. It was slick with his own come. Ominis knew that was one of Sebastian’s favourite things to do, smear it back around as lube for the final few thrusts.
He brought his head forward, kneeling beneath the table, and gently sucked Sirius’ soft, sensitive cock into his mouth. Sirius’ cried out, a muffled sound indicating he was holding back, biting his fist perhaps. Ominis licked him slowly, carefully, exactly as Sebastian had done to him the night before.
“You’re killing me,” Sirius panted, while Ominis finished and began manoeuvring his way out from beneath the table. “You’ve both killed me.”
Ominis straightened, and put a hand out, finding not the back of Sirius’ thigh but his knee, meaning he’d turned back over and now sat on the tabletop.
“Not dead,” Sebastian said. “Not done, either. Help me with Ominis.”
After all that time giving orders, feeling in control, it seemed like a reward to clear his mind and do exactly as Sebastian told him. It took only a minute for him to be stretched out naked on the same table Sirius had just vacated, Sirius stroking him from the side while Sebastian held his legs open at the thighs and fucked steadily into him.
“Look at him,” Sebastian said to Sirius—not an order, either, but a suggestion, his voice heavy with genuine awe. “Isn’t he the most beautiful thing you’ve ever seen?”
“Well,” Sirius said. He was beginning to sound more like his normal self, confident and smooth. “You’re nothing to sneeze at, either.”
“Shut up,” Ominis said, grinding down onto Sebastian, urging him deeper, faster, harder. “Shut up and fuck me, Sebastian, or I swear—”
Hands curled around Ominis’ wrists, tight to the edge of painful, and pinned them down beside his head. Sebastian leaned forward, and Sirius’ hand went still where it was trapped between their bellies.
“You’re lucky tonight’s all about you,” Sebastian said, nipping at Ominis’ neck and then licking the spot before it could begin to sting. “Now you shut up, and let me fuck you how I please.”
He shifted back, and Sirius flexed his freed hand before returning to the stroking. Even if Sebastian had made a little show about Ominis telling him to shut up, it was worth it, because it was then that Sebastian began to move in him exactly how he wanted. Driving into him, rolling his hips, grinding deeper even when there was nowhere else to go, and leaning back before doing it all over again.
That, Ominis was accustomed to, and it still felt fantastic every time. He nearly wanted to stay that way forever, except he also wanted to come, and the addition of Sirius’ hand meant he was not going to last very long at all.
“Sirius,” Sebastian said, his voice low and ragged. “Kiss me.”
For the first time in the entire encounter, Ominis felt a spark of jealousy, and it was only because they’d been able to watch each other kiss, and he couldn’t. He arched up off the table, and reached out, finding someone’s shoulder—Sebastian, he figured by the angle—and following the line of his neck up to his face. His fingers found where their mouths were joined, and then were immediately surrounded by tongue.
It was the textured slide along his fingers that pushed him over the edge, and Sebastian, with timing that usually eluded them, groaned around Ominis’ fingers and Sirius’ mouth as he thrust deeply.
Ominis fell back against the table, and Sebastian followed, lining their bodies up neatly, breathing hard in Ominis’ ear. There was a quiet, still moment, the kind that always followed their fucks. Normally, Sebastian would pet Ominis, and Ominis would snuggle up against him, and then they’d either sneak out of wherever they’d hid, or fall asleep if they were in bed.
But Ominis was very cognisant of Sirius, who’d gone quiet. Not even any sort of heavy breathing gave away his position.
“Don’t tell anyone,” Sirius said abruptly. His voice was cold and hard; Sebastian stiffened in response, and lifted himself off the table.
“Why would we?” he asked, sounding just as unfriendly.
“Hold on,” Ominis said, sitting up. “Let’s not—”
“It’s all well and good for you two to be perverts,” Sirius said, ignoring Ominis’ attempt at peacekeeping. “Gaunt is already disowned, and you, well, we all know you’re one wrong move away from having your wand snapped…I’d hate to have something to report to my father…”
“Fuck you,” Sebastian said.
“Stop.”
But they’d listened to Ominis only when their brains were hazy with desire. Now Ominis was about as powerful as a toad.
“Just keep your mouths shut,” Sirius said, “and we won’t have any problems.”
“We wouldn’t have told!” Sebastian said hotly, which tugged on Ominis’ heart. There was a lot of hurt beneath his anger.
Sirius said nothing else. The room was quiet as Sebastian handed Ominis his robes, and he pulled them on assuming they were doing the same.
“You really didn’t have to threaten us,” Ominis said once he was finished dressing. “It was—”
“He left, Ominis.”
“Oh.” Ominis rubbed his nose, hoping his disappointment wasn’t openly written on his face. “He has the quietest footsteps.”
“Cause he’s a snake,” Sebastian said viciously. He took Ominis’ hand with a softness that contradicted his hard voice.
“Because snakes don’t have feet, very clever.”
“I thought so.” Sebastian tugged Ominis forward, and they moved out of the Restricted Section together. “But then I also thought Black would be alright, so what do I know?”
“Don’t be angry with him. That was…a lot. Wasn’t it?”
Sebastian squeezed Ominis’ hand. He did it so often, and it was a comfort every time.
“I know,” he said, and there was a sudden softness to his voice, a relenting he couldn’t have allowed in front of Sirius but which was acceptable when it was just the two of them. “I’ll try to apologise.”
True to his word, he did. Three days after their night in the library, Sebastian went off to find Sirius. When he returned, he told Ominis about their brief but explosive reunion. He had, he said, a black eye, and a cut across his bicep that went clean through his robes.
“So, it went well?” Ominis asked, hiding his disappointment behind teasing.
“Swimmingly. I believe he’ll be agreeable for another round soon.”
It was lucky that Ominis only knew of Sirius Black, and did not know him. There was no hole in his life, nothing missing, no grieving to be done. He and Sebastian reminisced on the threesome once, while touching each other in bed, but then after Ominis felt guilty, getting off to the memory of something that Sirius seemed to regret.
Ominis told Sebastian this, and, for all the years they were together, they never did it again.
