Work Text:
It was undeniably exhausting, even for someone at his level of skill, to spend such extended periods of time in a disguise that forced his every muscle to morph in unsightly ways. No stage of the Hunter exam so far– and, Illumi supposed, still left to clear– had been particularly challenging, but to partake in all of it as Gittarackur meant he'd been looking forward to the next opportunity to shed his disguise.
This opportunity came in the guise of a small but private room assigned to him aboard the Chairman's airship— most candidates were sharing sleeping quarters, he knew, or stubbornly keeping vigil in the hallways out of distrust that they wouldn't be murdered in their sleep– in this case, understandably, no one had volunteered to sleep in the vicinity of certain candidates.
Closing the door behind him, cloaked in the room's darkness, Illumi decided to shed his disguise for now. If anyone happened to intrude, he could simply stick a needle in their neck.
One pin came off, a facial muscle wobbled unsteadily. Another pin, and another. More wobbling muscles like cold jelly. His hair grew back out to its natural length, smooth and a reassuring weight upon his shoulders, his chin popped, and the next time he blinked, his pupils felt as wide as they should've.
"That's always fascinating to watch."
Illumi didn't jump. He didn't startle. A swift toss of a needle that would have made its mark had the target been anyone other than Hisoka, lounging against the wall across from him, who snatched it an inch from his nose with sinfully long fingers.
"Get out," Illumi said tartly.
Hisoka clicked his tongue. "You don't mean that."
"I mean it." Illumi flicked on the light switch. Just so he could point at the door. "Leave."
Hisoka flipped the needle in his hand and, in a gesture that was both absurd and characteristically natural for him, sucked the round head of the pin against his tongue. His eyes, narrowed with amusement and obvious lust, never left Illumi's cold, dead stare.
"If you do not take your leave, I will kill you."
Now Hisoka's eyes properly lit up. "Will you really?"
But of course that threat was going to do the opposite of what it was intended to do. Illumi himself had an unconventional relationship with the idea of death, but he had to admit that the dimensions Hisoka took it for were ridiculous even by his family's standards. Illumi considered killing an art form, one that was adaptable as the circumstances saw fit, and sometimes a necessity, sometimes just a job.
Hisoka flirted with the idea of murder. Associated death, fighting, murder and arousal with each other. Illumi wasn't even sure what he wanted from him right now. Perhaps all of the above? He would not be surprised.
"What do you want?"
Hisoka tsked, although he finally pushed away from the wall and dropped the needle. "My, so direct, darling. Don't you feel like playing this game a little longer? Where we pretend sex isn't the reason we're both here?"
"The reason I'm here is to sleep," Illumi pointed out, deadpan.
"You'll need plenty of that," Hisoka's mouth curved into a wide, sly smirk, "When I'm done with you."
And here, Illumi realized he'd let his guard down. With his exhaustion, half-hearted engagement in their banter, and the greater part of his focus dedicated to ignoring the little things about Hisoka's demeanour he found disproportionately attractive even now, he had failed to notice the threads of aura sticking to the palm of his hand and the light switch. Hisoka knew the moment he registered his mistake. Just as the light flickered off again, he was zapped close, weightless, trapped beneath Hisoka's weight on the bed with their fingers perfectly entwined above his head.
His free hand that instinctively darted for the pressure point on the other man's neck was caught and pinned down too.
"You always know how to turn me on," Hisoka praised, mouthing the side of his neck. Illumi's hand clenched around his in a death grip.
He could stop this if he wanted to. He would not even have to use force (as much as his perverted acquaintance would enjoy that); Hisoka was many things, but he also understood when to stop, and a firm refusal would do it.
Illumi did not really want to stop. He had not wanted to sleep either; that had been a lie. He could go for several days at a time without sleep. He wanted to relax. Just a little bit. Maybe he could simply ask Hisoka to do it for him.
"Serve me" would be coming on too strong. "Service me" sounded like he was a broken vehicle in need of repairs. "Take care of me" sounded far too intimate.
"Stop wasting time and fuck me," said Illumi, pleased with final his choice of words. That should do.
Hisoka faltered, halfway into dragging off Illumi's pants.
Why is he suddenly embarrassed? This was his idea.
Illumi left him to it. His trousers wound up on the floor. Hisoka kissed a trail down his toned stomach, slipping his thumbs under the waistband of his boxers. Kissed the sharp jut of his right hipbone. His mouth was hot against the skin it touched, enough to make Illumi squirm.
Foreplay— Hisoka enjoyed it too much for his liking.
But soon long fingers with hazardous sharp nails were tugging him free, and the salacious, wet tongue pressed to his tip drooled enough saliva to facilitate the back and forth drag of Hisoka's thumb along the underside of his cock. He closed his mouth around the head, wrapped him in his fist, and made his thighs go tight with tension as he fucked his fist and his mouth with Illumi's cock.
Hisoka took him deeper, swallowed thickly around him. More saliva and drool wet his length, catching against the cold night air and mixing with his own precome as it pooled obscenely on his stomach. Illumi breathed a little heavier.
He was not vocal in bed, but Hisoka could change that. Oh, he knew full well how much Hisoka enjoyed making a game of drawing noises from him. It took time, but he liked taking his time, and the few times in the not too distant past where Illumi had allowed himself to be tempted, Hisoka had always got what he wanted.
He was almost certainly already on the right track tonight. Sharp nails briefly skirted the pale skin under his thighs before his underwear was pulled all the way down to his knees, getting shrugged off completely when Hisoka gave him the room to do so, never unrelenting from sucking him off.
An excited shiver ran down his spine at the first brief press of those dangerous nails.
His very first time, Hisoka had been considerate enough to snap two of his own nails off. Unused to taking anything inside him, Illumi hadn't made an issue of it, but later, as he was preparing to leave and his insatiable acquaintance was trying to cling on to him so that they may sleep huddled together, he'd declared that he was not so fragile that such precaution had to be taken.
Next time, Hisoka had eagerly promised. Illumi realized belatedly how he'd asked for a next time.
Maybe he was a bit of a freak too.
A soft but keening moan escaped his throat at the first press of a finger inside him. Hisoka pulled away from his cock, so close to orgasm, aiming a smirk at him that was both disarming and annoying, before shoving the second finger without warning.
His orgasm hit him with sudden force, hips jerking once before he came all over Hisoka's face.
"Over so soon?" he teased, his fingers picking up their pace.
"No," Illumi scowled. "Hurry."
"Mm, insatiable. I like that."
"Speak for— ah, hngh— speak for yourself."
Hisoka kept fucking him on his fingers, the drag fast, and sharp, and painful with only precome and saliva as lube, but it made his tired muscles go pliant with pleasure and his body tremble in ways that Hisoka alone could wring out.
And it felt good, the pain, pleasure, everything in-between— before Hisoka abruptly slowed to a stop, and he was left feeling devastatingly empty.
"Why did you stop?" Three needles appeared in his free hand, the one not clutching onto the sheets for dear life. It was more a reflex than anything.
Anyway, the promise of death by his hands only motivated Hisoka.
"You're bleeding." Hisoka had the gall to encircle his wrist and put that hand away, deadly needles included.
Illumi blinked slowly. Was he? He had not even noticed. Blood and injury was such an everyday part of his existence that if he wasn't going to die from it, he usually didn't feel it.
Hisoka had the audacity to get up off the bed.
"If you stop now, I will kill you."
"You should stop threatening to kill me all the time. That's the opposite of a punishment." He brushed the dust off his sleeves. All this time, and he hadn't even undressed. "Stay put, darling, I'm only going to look for something to use as lube."
Illumi's dark aura spread like a halo around him, but it didn't even deter his acquaintance, although it did make him find their solution with haste. Hisoka returned not a moment later with a bottle of lotion nicked from the tiny en-suite.
"I don't care if there's blood."
"I do." Almost placatingly, Hisoka pressed a kiss to his thigh lifted up above his shoulder. He poured most of the bottle down between his cheeks, gathering the excess with two fingers, pushing inside again with relative ease compared to the last time. Illumi sighed, dropping what would've become real bloodlust had he been left high and dry. He tossed his head back, exposing the long line of his slender throat. Felt Hisoka's eyes linger on his most vulnerable spot. A third finger pressed into him. He sighed again, clenching around the stretch, muscles tightening and relaxing with shuddering pangs of pleasure.
"You enjoy this," Hisoka observed, tonguing the crevice of his knee where it hung over a muscular shoulder.
He did. He couldn't dispute that. As much as he wanted Hisoka inside of him, there was a thrill in this that reminded him of the first time in ways that felt inappropriate to admit.
The first time, when he'd been on a job and Hisoka happened to be around, with his bad flirtation and annoying allure. He had taken something from Illumi that day that he'd never considered particularly precious, but he'd also given him something he'd never had a taste of before.
Something that felt dangerously close to disobedience. That felt nearly like rebellion. The first time he had done anything besides strictly the job he was there to do, and while it may not have been in direct defiance to his parents or upbringing, it felt just as liberating.
"Yes," Illumi agreed.
Hisoka cracked a smirk against his skin.
"Then, if I may be permitted..."
A loud gasp wrenched its way from out of his throat at the unexpected insertion of a fourth finger. He trembled at the stretch. Tried to open his legs wider, looked down with disbelief, confusion and intrigue in his eyes.
"What are you— Hisoka, what–"
Hisoka curled the four fingers inside him. He felt like he was tethering on the edge of falling. He was breathing faster, almost panting, muscles spasming and clenching from the impossible stretch.
"One more," Hisoka sang, and a raw scream resounded in his ears that did not sound like him, his breath coming to a complete stop for the instant that Hisoka's entire fist wore his insides like a glove before it curled and made him scream again, and he was coming then but in far too much pain to feel it. Hisoka chose that moment to rise up his body and capture his lips for the first time, resulting in something that felt like asphyxiation before he went numb, and his leg was being lowered again and that emptiness was back.
Hisoka kissed him roughly.
Their teeth clashed. Tongues, too. He could taste himself on the magician's tongue. Normally this would be a dance for dominance, but tonight, Hisoka just took and took from him.
"Gods," he swore, breathily, panting into Illumi's mouth. "I want to fuck you. I want to fuck you so badly."
Illumi threaded his fingers through red hair. He noticed how unexpectedly soft it was. He tightened his grip, pulling hard enough to earn a sharp hiss from the other man before forcing their lips back together.
"I hate you," he gasped into their kiss. That earned him a chuckle. He didn't stop. Hisoka didn't, either.
"I want you to kill me." Hisoka kissed the jut of his throat. "Someday, I'm going to die by your hand."
"You couldn't afford me," Illumi quipped, earning a real laugh that prompted a slight smile from him as well.
He kissed the back of his neck. It was hot there, and damp with sweat, enough to make the pillow cold.
"What's your rate? Do you charge by the hour?"
Illumi yanked him again by the back of his head to kiss the vulnerable point of his throat this time.
"No. By the value of the target."
Hisoka laughed. "Then was that a compliment just now?"
"Mm. I suppose." He was more aware of the cold air on his skin now. Drying sweat, tears, come and whatever else involved. "You will not be an easy target to kill."
"Don't say things like that. I haven't come yet, it's going to make me."
"Ah." Illumi blinked, languidly, digesting that information. He had not realized. "I am not taking you inside."
Hisoka pouted childishly. "Was that too much for you to handle?"
"No."
He raised an eyebrow.
"It was not."
"You're lying."
"I would have told you to stop."
Hisoka considered it. "Tell me the safe word we agreed on."
"What safe word?"
The magician snorted. "That's exactly what I'm talking about..."
Illumi stared at him. Hisoka gawked.
"Wait, you're serious? You don't remember having this discussion?"
"I remember saying you were a– what is that word Kil uses? Wimp?– for wanting to have one. I drowned out the rest of the discussion."
"So this is the Sex Ed the Zoldyck family imparts on its children..."
"Don't bring my family into this. I am perfectly educated in all things."
"You called me a pussy for wanting us to have a safe word."
"Oh, that is the word he uses."
"Do whatever you want," Hisoka grumbled, sitting up next to him on the bed. "This discussion made me dry."
Illumi pointedly stared at his crotch.
"...I wouldn't mind," he admitted. The assassin elegantly pushed himself up on his elbows and rolled to sit on his knees, tucking long black hair behind his ears.
Illumi woke up feeling like he'd maintained a transformation for three months straight. Every muscle and bone in his body ached. Had he not been trained to deal with fatigue and varying degrees of pain, he would have definitely felt a lot worse.
Adding to his irritation was Hisoka, who'd fallen asleep with all of his body weight on top of Illumi's right arm and looked far too peaceful at the moment. His back was scarred red from Illumi's nails, bruises and bloody rings littering the expanse of his collarbone and shoulders, and his neck red too from the imprint of Illumi's fingers around his throat.
He could cover it all up, anyway. If he spent extra time working on his Texture Surprise this morning, all the better.
Illumi would just have to incorporate hiding his own bruises and love-bites into his disguise. It mildly irritated him how easy Hisoka had it.
"Lulu~"
"Let go."
He clung more stubbornly to the arm that Illumi had wrenched out from under him. He was definitely not in as deep a state of sleep as he pretended to be.
"Always so cold to me..."
"I recall telling you to go back to your own room after we were done."
He mumbled something incoherent against his skin.
"Repeat yourself. I did not hear you."
"I said," Hisoka finally cracked open an eyelid. "This is my room too. They assigned us to share."
Illumi blinked.
Silence. He blinked again, then stared incredulously.
"There was only one bed."
Hisoka yawned obnoxiously. "Logistical error. Anyway, we had to share because everyone else was too creeped out by us, do you believe it? Isn't that hilarious?"
"...you did not think to inform anyone of this mistake?"
"No. Why would I? I was going to sleep with you anyway."
Illumi opened his mouth to say something. Then shut it. Then opened it again.
"No one will notice," Hisoka sighed. "It'll be fine. Anyway, nobody will believe it. Me, sleep with Gittarackur? Not on your life."
"Gittarackur is better than you deserve, and I am completely out of your league."
Hisoka sniffled. "You're so mean, Illu..."
Illumi sighed, shoving him. "We have to leave for the morning briefing. I do not wish to be seen exiting with you, so let me get ready first."
He wrangled his arm free from Hisoka's grip to some more complaining from the magician. This was the first time they had woken up together, still in the same bed. He was loathe to admit that he didn't hate it, but that was a concern to be cross-examined a different day.
For now, the next phase of the Hunter Exam awaited them, and, of even more interest, his eventual confrontation of an elusive rebelling younger sibling.
