Work Text:
Lacuna: an unfilled space or interval; a gap.
Jayce has had it pretty rough lately. From heaven to hell to this somewhere in-between where he spends most of his waking hours in the lab with Viktor trying to find a way to make things finally work, racing against the ticking clock that looms over their shoulders. He knows he’s onto something, can almost taste it in the air, how the whole entire world buzzes with silent anticipation—the feeling of it not that different from the rune adorning his wrist.
Tonight, he feels it in the air again, like he’s on the verge of a breakthrough. Electricity seems to pool in the atmosphere like a gathering storm but the skies outside are clear of any clouds, the first stars glittering against the dark indigo. Jayce cannot put a finger on what exactly is happening, but his heart is pounding, skin raised in goosebumps. Something is shifting —he doesn’t know what or how, but the bracelet over his wrist seems to almost sparkle, and he keeps fiddling with it as he rushes toward Viktor’s lab.
It’s a little late in the evening, but he is pretty certain he will find Viktor still there—the man is just as obsessed as Jayce is, a trait that has served to pave the road of their tentative partnership. Maybe he can help Jayce shape this weird energy into something useful, maybe run some numbers or double-check the equations once again, just to be sure. The spheres are so close to being stable. His feet are touching the edge, already, and he knows it’s only a matter of refining the science before he can take the leap forward.
(It’s not like he has any other choice.)
There’s light coming from beneath the door once he makes his way to the lab, and Jayce smiles to himself, already planning his speech to convince Viktor to let him order them takeout. The man has way too much pride sometimes, and honestly, Jayce just wants him to eat something better than the terrible cafeteria food Viktor likes to indulge in.
The door is locked when he gets there, which is weird . Jayce fishes out his key from his pockets and unlocks it, freezing on the threshold once his eyes adjust to the penumbra inside.
What he sees feels like a fever dream.
There’s someone there , in between Viktor’s spread legs, shoulders so big Jayce is sure Viktor is straining just to accommodate the man. The stranger’s head bobs in an unmistakable way and even though Jayce cannot see anything, he burns with embarrassment at having caught his partner in such a lewd position.
(He also ignores the part of him that itches with the newfound information that Viktor is, apparently, into men. Of course Jayce had heard the rumors, but a true man of science only believes in proof. The cut-off moans he hears are more than enough for him to accept this postulate).
A truly overwhelming mix of emotions swirls in his chest. He is ready to—to leave and pretend he never saw anything, confused as to why that leaves him reeling, but then Viktor speaks.
“ Ah —fuck, Jayce —right there.”
Fuck. What? Jayce stops in his tracks. Viktor’s accented voice sounds nothing like what he’s used to. It’s drenched in desire, raspy and sensual and so fucking good Jayce finds himself turning back around, beckoned by the siren’s call of his partner’s moans.
It takes Viktor a beat to see him. When he does, the fucked-out expression on his face morphs into shock—guilt flashes by, followed by something else Jayce cannot put a name on—and he tries to sit up straighter, the hand he has on the stranger’s head tugging him off his cock.
There is way too much gentleness in that small gesture. For some reason, it grates on Jayce’s nerves.
Viktor clears his throat, splotches of red blooming on his sharp cheekbones. “What are you doing here?”
“I came to see you,” Jayce mumbles, fighting the urge to cross his arms over his chest like a child. “I thought—I needed to work, but—you’re obviously busy, I’m sorry I interrupted—”
“Jayce.” This, at least, is familiar. Viktor always sounds… sweet, whenever he interrupts Jayce’s spiraling thoughts. “We need to talk.”
“He can leave,” the man between Viktor’s legs grumbles, finally turning around. Jayce sees a beard and unkempt hair, wrinkling his nose at how… uncivilized this man looks. Viktor’s taste is certainly a surprise. In the very few moments he allowed himself to entertain those rumors, he always pictured Viktor’s paramour as someone sophisticated. Elegant and well-read, that would have enough intelligence to keep up with his brand of witty humor. Someone that would treat him right.
(Someone like Jayce.)
“And who are you?” Jayce spits back, taking a step closer to Viktor in some misguided attempt of protection when the man simply laughs, humorless and gritty. “This is our lab. You can’t tell me to leave.”
He doesn’t know where that comes from, but the way Viktor makes a small sound of surprise fills Jayce with warmth. Like he has accomplished something—like his presence is a lot more welcome than the man still on his knees between Viktor’s legs is.
“Would you… do you wish to stay?”
Viktor’s question robs him of breath, pokes at that part of himself he has kept under wraps ever since they became sorta-friends. Viktor saved his life that day. Jayce couldn’t afford to pay that back with unwelcome advances.
The stranger huffs another bitter laugh, shaking his head. Jayce wants to punch him. “Of course he wants to. I would have.”
Jayce doesn’t understand what the fuck he means by that, but he snaps out of his stupor and finally approaches Viktor, taking a seat by his side on the couch. He knows better than to let his eyes wander down, but when the stranger tips forward and starts shamelessly sucking Viktor’s cock again, he can’t help it. His hungry gaze takes in Viktor’s heaving chest framed by his open shirt, vest nowhere in sight. His flat stomach is almost concave, a smattering of hair running from his belly button to the base of his cock, where the man’s lips leave behind a trail of glistening spit as he bobs his head—there is something almost reverential to how he does it, how his big palms encircle Viktor’s legs without ever gripping them, rubbing back and forth until Viktor sighs, hips pushing into his willing mouth.
It’s like Jayce is intruding on longtime lovers. He has no idea how he got himself in such a predicament.
Perhaps sensing his awkwardness, Viktor takes his hand in his, lacing their fingers together. His other hand pushes the stranger’s hair back, finger tracing the subtle scar on his eyebrow. “Jayce, this is— ah , this is you. From the future.”
What.
“ What ?”
The man looks up, and their eyes catch. There is a moment of recognition—he knows those eyes, knows that exact shade of gold that is so unique to the house of Talis—but his brain immediately rejects the idea of it, threatened and afraid.
“Vik,” the man whispers, pulling Viktor’s attention to him and completely ignoring Jayce’s confusion. “Can I eat you out? Please, sweetheart?”
The way Viktor blushes and immediately agrees should be… illegal. He spreads his legs as wide as he can, knee brushing against Jayce’s. The small touch shocks him into action, and before he notices it, his hand has come up to rest over the brace on his leg, the metal skin-warm against his fingers.
Sweetheart . Jayce isn’t one for pet names, but somehow this one… fits. It feels right to address Viktor like that. His only gripe is that he isn’t the one who thought of it first.
(Which—maybe he has. If that man truly is Jayce from a different point in time. Maybe he gets to call Viktor that at some point, for the first time.)
“Where’s your Viktor?” The question slips out before he even registers it in his mind. His future self freezes in place, though, face hidden in shadow when he mumbles, “Not here.”
Future Jayce busies his mouth then, licking into Viktor’s body with a shameless hum of pleasure that makes Jayce’s stomach twist. He watches in fascination as the man slips a finger alongside his tongue, the slight movements of his arm betraying exactly what he is doing.
Jayce’s heart is beating wildly against his chest. He realizes with a start that he wants that. Wants to taste Viktor where he is most private, wants to be the reason why he gasps and trembles like he is doing right now.
This past month has been so full of ups and downs Jayce hasn’t had time to stop and truly examine the exact nature of his feelings towards his new lab partner. It’s a shame it takes something as ludicrous as time traveling for him to pause long enough to realize just how pretty Viktor looks in the soft golden light that spills from the lights outside in the street.
Future Jayce does something that earns himself a long, drawn-out moan. Viktor’s leg spasms under his hand. Jayce tries to soothe him, pressing against the strained muscle until he relaxes against the couch.
“Apparently we fuck up the gems,” Viktor murmurs, his accent coming in thicker as he stumbles over the words. His long lashes flutter against his cheekbones, delicate and so mesmerizing Jayce wants to kiss the bruised skin under his eyes. “S-Something goes wrong.”
Jayce looks at his future self—who is already looking at him. Something passes between them and Jayce decides he doesn’t want to know. The grief behind Future Jayce’s eyes is way too heavy for a moment like this.
Thankfully, they break away when Viktor moans again. He squirms against Jayce’s side and clutches onto his shirt, mumbling something in a language Jayce has only ever heard in passing, but that Future Jayce seems to have no problem understanding. The man redoubles his efforts, filling the room with absolutely filthy noises that go straight to Jayce’s dick, making him strain against his slacks.
“Jayce, can you—touch m-me?” Viktor asks with lidded eyes, index finger tracing his wrist. He is completely powerless to resist such a request, and even if he trembles a bit he closes a fist around Viktor’s cock and pumps it slowly, from base to tip.
The effect is immediate. Viktor cries out in pleasure, dripping precum over his fingers, and Jayce polishes his head the way he himself likes, spreading the slick on his way down. He is transfixed by the way Viktor is practically melting against his side, hiding his face on his shoulder as he moans and moans, only going silent when he finally cums.
It’s truly a sight to behold.
In the aftermath, Future Jayce pulls back with a smug grin, resting his head against Viktor’s thigh as he catches his breath. He looks at Viktor then, and his whole face softens into an expression Jayce has never seen, so full of longing he has to physically shake his head to avoid thinking about why he would be looking at Viktor like that.
It’s then that Jayce notices his hand is covered in Viktor’s jizz. His mind is pleasantly numbed by the sheer amount of new information it’s trying to process, so much so that he doesn’t even falter before bringing his fingers up to his mouth and tasting the sticky mess coating his fingers.
It tastes bitter. But not unpleasantly so.
“Jayce— what the fuck .”
“What? It’s not like you never licked the gems—”
“That’s so completely not the same thing,” Viktor says with a shake of his head, baffled despite the way he still looks sex-drunk. He bites his lip, hazel eyes lingering on Jayce’s mouth. “Did you like it?”
“It’s… not bad,” he lies, and then adds, “I wouldn’t mind sucking you off next time.”
He blushes the minute he realizes what he just admitted to. There it is again, he thinks, always rushing twenty steps ahead. He hasn’t even kissed Viktor yet, for crying out loud, and here he is, assuming there will be a repeat performance of whatever tonight—
“I’d like that,” Viktor says, and then he kisses him.
It’s like a spark igniting, that first flicker before the forge lights up. Something inside Jayce’s chest rattles in place, and for a brief second, the world outside fades away. Their kiss starts a bit awkward and that’s entirely his fault—he is frozen in place, brain halted to a stop—but then he feels Viktor start to pull away and he simply…cannot have that.
His hand finds Viktor’s face and gently tips him sideways, letting their mouths fit together. Viktor hums in approval, and Jayce glows, sighs into it, parts his lips and lets Viktor lick into his mouth. It feels so good . Jayce has always liked kissing just for the sake of it, but this feels even better than usual—and it’s all because of Viktor.
When Viktor pulls away, Jayce whines, chasing after his lips like a puppy. Viktor grins, gives him one last peck, but his attention is already focused on Future Jayce, who is watching them with an undecipherable expression in his sad eyes.
“You’re not leaving, are you?” Viktor asks in a low murmur, reaching out for the man. Future Jayce meets him halfway, still on his knees as he lets Viktor cradle his face in his hand, dropping a kiss to his palm but never pulling away.
“I know when I’m third-wheeling, Vik. It’s fine.”
“But—you are not.” The man doesn’t look convinced so Viktor huffs, mouth curling into a small, adorable pout. “You said you’d give me anything I wanted. You promised .”
“I did.”
This is news to Jayce, and he doesn’t like the sound of that. He hates the fact that there’s so much he doesn’t know , so much history between these two people who cannot have known each other for longer than a day—it certainly feels like more than that, especially if promises like that have already been made.
It feels way too intimate. Their gazes are too charged, especially Future Jayce’s. He keeps kissing Viktor’s hand, the picture of perfect devotion as he waits on his knees for Viktor to make a decision.
He does look handsome, Jayce has to give him that. Maybe it’s the beard.
“Oh, Jayce,” Viktor murmurs, flushing pink as the man smiles at him, encouraging. “I want…I want you to fuck me.”
It takes them both by surprise, hot jealousy bubbling up Jayce’s throat as Future Jayce murmurs, “Really?”
Viktor nods, looking more confident as he turns to look at Jayce. “And Jayce—I want you here. I want you in my mouth.”
“Viktor! That’s so—”
Viktor laughs, shaking his head. He looks so light. “When will I ever get the chance to have two of you again?”
Future Jayce chuckles, groaning softly as he gets back on his feet. “He has a point.”
“Shut up.”
Future Jayce shrugs, stretches his arms. Viktor shamelessly ogles him, eyes lingering on his impressive arms, but Jayce is surprised to find a brace on Future Jayce’s leg, the design lighter than Viktor’s but impossible to mistake for anything else.
Huh. He files that information away into a tiny little box in his mind, trying to memorize the details to maybe make something similar if Viktor’s condition ever deteriorates to that point.
Future Jayce sits down by Viktor’s side, hands immediately going to him. It sends a hot shiver of something through his body to see how much bigger his hands are, how easily his future self encircles his waist.
If the soft moan he lets out is anything to go by, Viktor seems to appreciate it too. His soft cock gives a twitch, already halfway to being fully hard again.
“How do you want me, sweetheart?”
“Can I ride you?”
Future Jayce’s eyes widen, swallowing dry. He looks dangerous all of a sudden, and Jayce shifts closer to Viktor’s other side, ready to pull him away. “What about your leg, honey?”
“I’ll be fine. You can… help me, if I need it,” Viktor says with so much certainty one would think he and Future Jayce have done this before, but that’s a hypothesis Jayce refuses to entertain.
“Let me know if that changes, okay?” Future Jayce says, pressing their foreheads together for a brief moment. “I don’t want to hurt you.”
The way he says it makes Jayce frown. He can almost hear an “ Again” at the end of that sentence, the same way he could feel it in the air earlier today that something big was happening. He takes in the careful way Future Jayce kisses Viktor, how he cradles his face and seems to always be touching him—like he needs to make sure Viktor is real, or alive, or something just as damming. Jayce has never been a man who feared the future—in fact, he always rushed towards it to the best of his ability—but it’s impossible to not put the pieces together, and the glimpses he starts to see make him want to halt everything until he can make sure he won’t end up broken like the man in front of him.
Future Jayce lets Viktor go for long enough he can shimmy out of his pants. His cock is… impressive, for as much as it pains Jayce to admit. He shoots Jayce a knowing grin, sharp and lascivious, and reclines back against the couch with his legs spread wide, beckoning Viktor close with a flick of his wrist.
Viktor goes. Of course he does.
He steps out of his clothes with a grace that surprises Jayce. Fully naked but for his leg brace, Viktor is one long sinuous line of sinful flesh dotted with freckles, the sharpness of his shoulderblades balanced by the vulnerable arch of his neck, tilted forward in the first bout of coyness Jayce has ever seen from Viktor.
It makes him feel… some type of way. Viktor is always so confident and sure of himself that seeing him like this births a protective beast inside Jayce’s chest, and he crosses the distance between them until he is plastered to Viktor’s back, kissing the soft skin behind his ear.
“You look beautiful,” he admits in a single breath, hearing his counterpart sigh in agreement. “Gorgeous,” Future Jayce adds, lacing his fingers with Viktor’s and tugging him forward. “Can I get a kiss?”
Viktor chuckles and finally seems to snap out of whatever had been making him hesitate, plopping down on Future Jayce’s lap gracefully. Future Jayce helps him with his leg, bends it carefully, and places a large hand around Viktor’s waist, touching the notches of his spine like he is keeping rhythm.
When they kiss, Future Jayce huffs like he is wounded, and the sight is hot, Jayce has to admit it. Future Jayce is at least two decades older than he is, perhaps more, and he looks different enough it isn’t weird to feel slightly attracted to him. He is a stranger, after all, one that kisses Viktor like a starved man, whose fingers part Viktor’s ass and aren’t shy to slip inside his body, stretching his rim around the intrusion.
Jayce can’t help the moan that escapes him and he perches on the arm of the couch, flaming cheeks as he watches Viktor tremble and get stuffed full of Future Jayce’s fingers. There’s a little bottle of lube lost in between the couch cushions and he blushes even harder when he retrieves it, doesn’t overthink it when he pours some onto Future Jayce’s hands when he asks for it, stomach squirming when his counterpart gives him a heated look from where he is sucking hickeys onto Viktor’s neck.
“ Ah —Jayce, please, that’s—feels so good,” Viktor babbles, looking the perfect picture of sin, spine bowed and grinding against Jayce’s lap like an expensive whore from the Undercity, sweat making his skin glisten. Jayce doesn’t think he’s ever looked more beautiful than right now, his cock so hard he finally opens his slacks and fishes it out, touching himself to the same rhythm as Viktor’s hips.
Viktor whines and moans and puts on a show for them—at least, that’s what it feels like for Jayce. He gains confidence bit by bit, first asking for more fingers and then demanding Future Jayce to hurry up. It sends a thrill down Jayce’s spine, this new facet of Viktor’s bossiness unveiling itself in front of his eyes.
“Think you’re ready, Vik?” Future Jayce asks, slowing down a bit where he is fucking Viktor open on three of his large fingers, holy shit. “You still feel so tight. We don’t have to rush it.”
“No, I want—’m ready,” he argues back, his pale chest heaving despite the certainty in his voice. “Want you inside. Now .”
Future Jayce chuckles, kisses his lips. He pulls his fingers out and brings his slick hand to his cock, pumping it to full hardness in lazy strokes. “What about Jayce over there, hm?”
“He can watch.” Viktor gives him a look, eyes molten. His gaze drops down to Jayce’s cock and he feels himself twitch, unjustifiably ashamed at having been caught. “Right? You can be good and watch me fuck future you.”
Okay. Jayce is learning a lot about himself today.
With a dry mouth, he nods. Viktor grins, all cocksure and pretty , and Jayce does as he was told, head all fuzzy at the approval shining in Viktor’s eyes. Jealousy still crawls inside his chest, but it’s easier to ignore when he feels the weight of Viktor’s attention on him, even as he looks away to kiss Future Jayce again.
When Viktor rises to his knees, Jayce holds his breath. Future Jayce lines himself up with his hole—he looks so fucking big Jayce is sure it won’t fit—but Viktor slides down without a hitch, taking his cock all the way with a quiet groan of pleasure.
Despite himself, Jayce finds his eyes drawn towards his counterpart’s face. His expression is twisted into something that could pass for bliss if not for the way his eyes are swimming with tears. He mumbles something that makes Viktor shake his head, his slender hands cupping his jaw as they kiss, way more gentle this time. There’s something so charged between them that Jayce looks away, falling short in how his own feelings feel shallow in comparison. For all he knows, Future Jayce has been in love with Viktor for a long while now, maybe more than half of his life. He could never measure up.
Viktor starts slowly rolling his hips, forehead pressed against Future Jayce’s, and the way his rim is stretched smooth around the massive dick splitting him open sure is a sight to behold. Jayce can almost feel the tight grip of it around his own cock, fucking into the tight circle of his fingers in tandem with their movements. In his mind, he can see himself bending Viktor over the single table of their small lab, can feel the way his body would flutter around him as Jayce took him right there so close to their research papers, how Viktor would sound when he scolded Jayce for being careless.
“You’re so, so beautiful. So gorgeous, Vik, so good for me.” Future Jayce’s voice snaps him out of his thoughts, calling his attention back to where he is just a voyeur to the man he wants. “Taking me so well, like I knew you would.”
Viktor eats up the praise, though, blushing despite the proud tilt of his jaw. “Feel so big,” he murmurs under his breath, casting his gaze sideways to look Jayce in the eye. “Wish I could take you both.”
Jayce’s mind completely blanks at that. Future Jayce seems to not be faring much better.
“Fuck—Fuck, sweetheart, always such an overachiever,” he groans, hands closing around Viktor’s waist to bounce him lightly on his lap, picking up the rhythm. Viktor throws his head back, mouth open and lips all shiny, and Jayce is so close to blowing his load he has to rip his hand away before he comes too soon.
Viktor said he would suck him off. He cannot lose that opportunity.
He gets up on shaky legs and gets close to him, the heat of Viktor’s skin hitting his poor cock in waves. He has to swallow down a lump when Viktor catches his gaze—he looks so fucked out, his sharp eyes clouded with pleasure.
“Viktor, can I?”
“C’mere, Jayce,” he murmurs, all soft and sly. When his slender hand touches the base of his dick, he knows this will be over embarrassingly fast, especially when Viktor says, “So good, waiting for your turn.”
Future Jayce chuckles, but doesn’t say anything. He is practically fucking Viktor down onto his cock with powerful thrusts of his hips that shake the couch underneath them, but there’s still that besotted look on his face that tells Jayce this man is just as wrapped around Viktor’s finger as he is—maybe even more.
Viktor’s lips are soft and plush around the head of his cock, a teasing kind of pressure that has Jayce worried for a moment—but then Viktor smiles and takes him inside, slowly bobbing his head as he completely obliterates Jayce’s self-control.
His hand tangles on Viktor’s hair, just to have something to hold onto. He can’t look away from Viktor’s blissed out expression, taking them both at the same time like he was made for this. Jayce watches him bounce on Future Jayce’s cock, legs slipping out from beneath him for a moment before his counterpart holds his weight for him, using him like a toy as he snaps his hips up. They look gorgeous like this, hair matted to their foreheads and the stench of sex in the air, something straight out of a porn magazine, making Jayce wish there was a way to capture this moment for posterity.
“He feels perfect. Best I’ve ever had,” Future Jayce tells him and Viktor keens, the vibrations traveling down Jayce’s dick in a delicious way. “You better take care of him, kid.”
“I will,” he promises, meaning it from the bottom of his heart. Viktor does something wicked with his tongue to reward him and Jayce falters, pushing as deep as he can inside of the perfect heat of his mouth. “Fuck, Viktor—just like that, please— please —”
Viktor blinks watery eyes up at him and hollows his cheeks. Jayce’s cock brushes against the back of his throat and he is done for, hips stuttering out of his control as he comes with a loud groan, buried to the hilt inside Viktor’s throat.
It feels so fucking good, like his orgasm stretches on forever. Pleasure washes over his body, weakens him.
A tap on his thigh makes him blink, chest heaving as he tries to catch his breath. He pulls out and a dribble of come spills from Viktor’s lips, a pink tongue immediately following it, and Jayce falls onto his knees on the hardwood floor, completely spent.
Viktor giggles, falling onto Future Jayce’s chest like he, too, has reached his limit, but Future Jayce doesn’t stop. His big hands hold Viktor’s hips and tangle in his hair, tilting his head back into a dirty kiss. There’s teeth and tongue and Viktor moans brokenly, spine bowed in a pretty arch when Future Jayce sucks a bruise on his neck, lavishing him in attention.
“M’ close, honey,” he warns Viktor in between groans, the slap of skin almost loud enough to drown out his raspy voice. “Can I? Inside?”
Viktor’s answer is a hiccup-y yes , raking his nails along the man’s strong chest. At some point that Jayce missed, Viktor had worked the man’s shirt open, and there is a stretch of golden skin he buries his fingers into, mouthing at his pecs like he needs it more than air to breathe.
At every thrust up, Future Jayce pushes Viktor down against him, stuffing him full. Jayce is too fucked out to be jealous, head too empty to think the sight is anything other than hot as fuck— especially when Viktor comes untouched. With a shout of “ Jayce ” he spills all over himself, Future Jayce following right after, balls twitching as he empties himself inside Viktor’s body with a groan.
The silence that follows is only broken by their breathing and the occasional car passing by down the street. Future Jayce drops a kiss onto Viktor’s head, adjusts him more comfortably in his lap, motions for Jayce to join them on the couch.
When he does, Viktor blinks his eyes open to smile at him. He reaches out to tangle their hands together, looking so at peace Jayce feels his heart squeeze with affection, happy despite the sheer absurdity of their situation.
“I told Vik what happens,” Future Jayce says, hands combing Viktor’s hair back in soothing little motions. “Please—listen to him, alright? I can feel my time here running out.”
Viktor makes a noise at that, burying his head deeper into his chest. Jayce tries to not take it personally and instead nods at his counterpart, a silent vow to stop whatever it is that has made him into such a broken man.
He watches them kiss one more time before he excuses himself to the bathroom, wanting to set up a bath for Vikor and give them some privacy for their goodbyes. His legs must be sore after the activities of the day, and Jayce has noticed that he tends to soak up in the tiny tub on days when his leg acts up. Viktor comes to find him some time later, eyes red-rimmed but smiling, exhaustion clear in the way he sags against the doorframe.
“We will fix it, right?”
Jayce hates how small Viktor sounds right now. There is no other possible answer. “We will. I promise it.”
He pulls him into a hug, finding that Viktor fits perfectly under his chin. They breathe together for a couple of seconds until Viktor’s body stops shaking in his arms. He looks up at Jayce, blinks, and then kisses him.
They will find a way. Jayce never backs down on a promise.
