Bigger & Grizzlier

Summary:

Keith disappears for two years, and Lance thought he’d never see his boyfriend again. No communication, not even a whisper of where he’d gone. For the longest time, Lance had figured he was off on some top-secret Blade mission – which wasn’t abnormal considering they were in the middle of a war. Keith would have missions where he’d be gone for three months and that would be perfectly normal. But when three months turned into four, and then four turned into five, Lance got really worried.

Notes:

In this au the galra have secondary genders which are where the ABO dynamics come into play. Lance is human and doesn't have a dynamic!

Work Text:

Keith disappears for two years, and Lance thought he’d never see his boyfriend again. No communication, not even a whisper of where he’d gone. For the longest time, Lance had figured he was off on some top-secret Blade mission – which wasn’t abnormal considering they were in the middle of a war. Keith would have missions where he’d be gone for three months and that would be perfectly normal. But when three months turned into four, and then four turned into five, Lance got really worried.

The next time Voltron had business with the Blade, Lance demanded to know where Keith was, and…Kolivan couldn’t tell him. Couldn’t even tell him what had happened to Keith. The dread and fear and despair that Lance had felt that day was akin to someone telling him that one of his siblings has contracted polio and they were going to die – and he knew how that felt. Vividly.  His sister died at the tender age of six before they could get the vaccine to cure her.

Lance feels like his world has just been shattered, crumbling and falling to pieces at his feet. The Blade had lost all communications with Keith when the base Keith was tasked with infiltrating to retrieve an undercover Blade who had intel on how to destroy a weapon the Galra were going to unleash that was powerful enough to destroy entire planets suddenly blew up.

By all counts, Keith should be dead. Lance grieved even though in his heart he knew that Keith is still alive, and it wasn’t that he’s in denial. He wasn’t. Keith’s a survivor, he always has been, and his idiot boyfriend is too stubborn to just go and die – explosion or no explosion. Keith is out there somewhere. He knows it. He doesn’t care how many times he has to endure the looks of quiet pity and sympathy the rest of the team gives him.

Kolivan and Keith’s fellow Blades have even taken to…hovering around him whenever they work together. Almost like they assume he’s going to drop dead or launch himself out of the nearest airlock. Which is ridiculous. He misses Keith’s stupid mullet, and his quick wit and dry humor. He misses the way he smells, has taken to sleeping in the Red Paladin’s room just so he can catch a whiff of his scent under the covers and on his pillow long after his scent has faded.

He misses his boyfriend.

The first time he’s caught coming out of Keith’s room by Regris, the Blade looks almost horrified, and Lance can’t quite figure out why he’s being ushered into the lounge and being smothered by the other Blades and made to feel like…family. It’s not that he’s complaining! It’s just… weird. The grooming and the nuzzling are something he can never get used to. He comes from a large family but this…pack mentality isn’t something he’s familiar with.

When he asks Regris what the hell is happening, Regris tentatively divulges information that makes his head want to explode.

Let’s just say, getting the Galra version of The Talk, is something Lance never expected to have. The fact that the entire Blade seems to be privy to his depression and his relationship with Keith was embarrassing. What was made worse was the fact that the Blade actually did believe that Lance was going to throw himself out of an airlock or get himself killed. He’d stumbled upon a conversation he was probably not meant to hear, but since it was concerning him, a little eavesdropping shouldn’t hurt, right?

Wrong.

Apparently, Galra form bonds with those they’re in a serious relationship with – permanent bonds. The Blade seems to be under the impression that he and Keith are “mated.” Which sounded wonderful in theory, except for the part where apparently if one mate dies, the other will sink into a deep depression and no longer feel the will to live without their mate. And yeah, okay, Lance is pretty depressed but he’s not gonna throw himself out of an airlock. He and Keith aren’t even “mated” or whatever. Lance thinks he’d remember such a life-altering event taking place.

None of them look entirely convinced when he tells them that.

And then one day out of the blue two years later, Keith comes back.

Except Keith came back different, came back more galra. His hair is longer, tied off into a long braid that rests over one shoulder. His ears are pointier, and he has a purple stripe going down one cheek. Even his sclerae are tinted a faint yellow, just enough to appear inhuman. And, oh man, the claws.

He came back even more beautiful, and more importantly, big. His shoulders are broader, and he’s taller than he was before he left, a whole head taller than him now, in fact. Lance has to look up at him now and it’s such an aggravating yet pleasant thought that his grumpy, little gremlin of a boyfriend is now bigger and grizzlier than him in every way. There’s something incredibly arousing about the idea that Keith could probably pick him up without breaking a sweat and manhandle his smaller body in whatever way he wanted.

So incredibly arousing.

Lance can feel his dick give an interested twitch at the mere thought of being swung over his boyfriend’s shoulders and carried off to have his wicked way with him; being dropped unceremoniously onto their bed, being manhandled into whatever position Keith wanted to take him in and let Keith pin him down and force him to take it.

Lance bit back a groan, glaring down at his dick. Now wasn’t the time to be thinking with his dick, not when Keith has information vital to saving the universe, and definitely not when Keith introduces his mother. But holy shit is he looking forward to the reunion sex once this is all dealt with.

Keith seems to be thinking along the same lines as him if the way Keith can’t seem to look away from him tells him anything; shooting glances his way with his eyebrows furrowed adorably. Keith’s always watched him, only now he does it with yellow in his eyes and an intensity that makes the hair on the back of Lance’s neck stand on end whenever he’s the sole focus of that stare.

Keith stares at him like he wants to devour him, and Lance… Lance wants to get him alone and see just how ravenous his boyfriend is for him after being apart for two years. That is, once his boyfriend is done with the countless debriefings and “important business that he needs to take care of first.”

Lance tries to be understanding, he really does, but for the two days that Keith’s been back, they’ve only exchanged a handful of words before Keith runs off with the excuse that he’s busy. It’s almost like he doesn’t want to be in the same room as him. Almost like he’s…avoiding him. Which fine, a lot can change in two years but Keith’s feelings for him are obviously not one of those.

If Keith didn’t want to be with him anymore, he’d say so. Keith is blunt and harsh at the best of times, but the looks Keith gives him are far from guilty or remorseful. No, they’re filled with hunger and barely restrained want. That isn’t the look of a man about to break up with him.

Lance doesn’t know why Keith leaves the room every time he walks in or why Keith seems to tense up, nostrils flaring; a heated look creeping into his eyes before he makes a hasty exit – doing absolutely nothing about the growing sexual tension that continues to grow between them.

It’s so frustrating.

Lance had the sneaking suspicion that his boyfriend is overthinking things again – as he tends to do – and probably thinks Lance doesn’t like the new changes to his body, or even worse, that Lance is scared of him now. Which is ridiculous. His hard dick is a testament to how ridiculous that is.

He’s got Keith’s schedule down to a T. He’s known him long enough to know Keith’s routine. Knows that Keith wakes up and starts his day by destroying the bots on the training deck. So, when four days pass with much of the same, Lance decides to take matters into his own hands. He makes sure he’s ready for when he finally confronts Keith. Lance makes sure to get up before Keith and heads to the training deck for when Keith will inevitably show up.

And just like he knew he would, Keith slips through the door at half-past six, quiet like he has no business being anymore that he’s so muscular and tall, and just his presence – the bulk of his body, the weight of his stare, the curl of his lip that shows just a hint of fang – is enough to have Lance’s heart racing, and Lance wonders if Keith can hear that now.

“Nice of you to finally join me,” Lance drawls, hands on his hips. “I was beginning to think I’d never get you alone.”

Lance hears a strange sound come from Keith then; a slow-rolling growl, like thunder far off in the distance. It sounds dangerous, and if it were any other galra, Lance would feel afraid but instead, the sound has his cock thickening in his too-tight jeans.

Keith takes a step towards him, and Lance takes a step back; a dance they’ve played a hundred times before, but it has never carried this much weight. This time is different, he knows. Keith is different.

Keith’s eyes seem to sharpen, his lips peeling back in a grin that is almost feral, and Lance knows that if Keith had ears and a tail like most of his galra brethren, his ears would be perked and his tail would be swishing behind him in interest at the prospect of a chase.

Keith looks like he’s ready to pounce.

Lance slowly backs away, and Keith follows; like they’re two opposing sides of a magnet, drawn impossibly together. Lance would laugh at the parallel, but he doesn’t. There’s nothing amusing about the way Keith’s eyes darken as he shadows his footsteps. Lance turns, glancing over his shoulder at Keith to make sure he’s following – and Keith’s staring, of course, he is – and Lance gives him a wink and a salacious smirk before he makes a run for it.

For a long moment, all Lance can hear is the door swooshing open and closed to allow him to leave, and the sound of his own thundering footsteps against the floor before he catches the sound of Keith sprinting after him. He’s indulging him. There’s no real chase, Keith could catch him in a split second if he wanted but he’s letting Lance gain ground, letting him think he has a chance of getting away. Adrenaline sparks in his blood, and he grins at the thrill it sends through him.

It really didn’t take as much effort as he thought it would to get Keith to fall right into his little game.

Lance races past the kitchen, through the winding hallways, and past the elevators. Lance spares a glance at their private quarters, but that would be too easy; would make their little chase over way too soon. He runs right past it, sprinting as fast as his long legs can carry him, and Lance catches sight of a few members of the Blade looking up at the commotion when he runs past the lounge. He’s running like he doesn’t want to be caught, but he does – and then he is.

Keith collides against his back and grabs his arm, grip like a vice, and stops his forward momentum with a jerk of his shoulder. Keith swings Lance around the corner and pins him hard against the wall with a growl, crowding against his back so that Lance’s upper body is pressed against the wall.

“What do you think you’re playing at, Lance?” Keith growls, his breath tickling Lance’s ear. Lance can feel the heat of Keith’s body against his back, effectively sandwiching him between his hard body and the wall.

Lance turns his head, catching a glimpse of Keith over his shoulder. Keith’s eyes are almost more yellow than purple now, his sclerae a solid block of yellow with his pupils slitted like a cat; as dark as the night sky.

“Trust me, guapo, I’m not playing,” Lance says, watching the way Keith licks his lips, showing off his fangs again.

Lance has a brief second to wonder if it’s the idea of when – not if because it’s always a matter of when Keith marks him up if he’ll use those sharp new fangs of his to bite him – that makes him arch his back and push his ass back against Keith’s crotch, surprised to find that Keith is just as excited as he is.

“Now?” Keith asks, voice rough as he grinds his cock against the swell of Lance’s ass. “Here?”

Yes, Keith,” Lance says like it isn’t obvious what he wants. “Right here, right now.”

“What if someone walks by?”

Ay Dios mío, Keith, I don’t care!” Lance doesn’t snap, but it is a close thing. “Let them see! I need you.”

That’s all it takes for Keith to release Lance’s arm and reach around to rip open the front of Lance’s jeans. Lance yelps in surprise, hearing the fabric rip and his button plink and spin across the floor as Keith tugs his jeans down to his thighs.

Keith leans back and kneels down, and Lance can feel the cold air against his bare skin in the absence of the heat of Keith’s body.  Lance groans, pushing his ass out more when Keith uses his thumbs to pry his asscheeks apart, getting the response he hoped for when Keith suddenly swears loudly.

Fuck, Lance,” Keith growls. “A plug? Really?”

Lance doesn’t bother hiding his face, he isn’t ashamed. He wants Keith’s cock in him like yesterday. He’s waited long enough, and he isn’t in the mood for foreplay or the slow, torturous way Keith likes to stretch him open on his fingers to make sure he can take his cock. Nuh-uh. Not today. He wants to feel it.

“Yeah, I thought – “

Lance chokes, his words abruptly cut off by a strangled groan as Keith pulls the plug out with zero warning; dropping it on the floor without a care, a low growl rumbling in the back of his throat like he’s jealous of a plug being in Lance and he was not.

Fuck, that shouldn’t be as hot as it is.

Lance twists, craning his neck back to get a look at Keith, his breath hitching when he sees Keith staring at his ass like it’s a three-course meal and he’s been starving his whole life. It’s still a bit too dark in the corridor, the only lights coming from the blue lamps lining the walls, the castleship still in the last half hour of its night cycle, but Lance had no doubt in his mind that while he can’t see clearly in the dark, Keith can see him as clear as day. Lance wonders if Keith is watching the way he’s clenching down on nothing, eager to be filled with his cock.

“Fuck,” Keith mutters. “Fucking hell, Lance. You planned this, didn’t you?”

“Of course, I did. You were taking too long to make a move, and I don’t know about you, but I’m gonna die if you don’t fuck me right now, Keith,” Lance says dramatically, shaking his ass for emphasis. “Was the plug big enough? Do you think I’m ready to take you?” Lance goads, curling his spine and pushing his ass out so Keith can get a better look at his gaping hole. “Because I’m pretty sure you could just slide that big cock of yours right in, Kitten. What do you think?”

Lance smothers a grin into his shoulder when Keith stills behind him, his claws digging into the flesh of his thighs as Keith lets out another one of those sexy growls that sends arousal pooling in his belly and his cock twitching between his legs.

The answer must have been yes because Keith immediately rises to his feet are starts unzipping his fly, and then Lance can feel Keith’s cock against him, hard and hot, and big. Bigger than Lance remembers Keith being, like everything else about him now.

“You sure?” Keith rumbles, ducking his head to nose along the back of Lance’s neck.

“Gods, yes,” Lance whimpers, scrambling for purchase against the wall when Keith trails his lips up the side of his neck to pay special attention to the spot just below his ear that never fails to get him worked up.

Then Keith’s fingers are slipping between his cheeks, a fingertip probing at his hole, carefully testing the resistance and checking to make sure he’s still slick with lube and stretched enough to take his cock. Lance reaches back to give him a hand, sinking two of his own fingers inside with a quiet gasp when Keith doesn’t do more than brush the pad of his fingers over his entrance – oh, right, claws.

Keith snarls and pulls Lance’s hand away, and that’s all the warning Lance gets before the blunt head of Keith’s cock is pressing against him. He was right to wear the plug, otherwise, this would definitely be too much too fast. Lance widens his stance – or tries too anyways, his jeans are still around his thighs – and Keith reaches around to place his palm on his stomach just above his aching erection to still him, to hold him in place more firmly than even the wall could manage as he slowly feeds him his cock.

Lance gasps, inarticulate when Keith finally bottoms out. Going from no sex at all – except for fucking himself on his toys, because c’mon, he’s no celibate monk and he has needs – for two years to finally having the real thing; to having Keith inside him again has him sagging in sweet relief.

Keith is alive. Alive and here with him. Alive and inside of him.

Keith still has a hand against his stomach, and he keeps it there as he pulls out nice and slow before thrusting back in – hard. Lance lets out a punched-out groan, the air stolen straight from his lungs. Keith presses his hand more firmly against his belly, and Lance has the wild thought that maybe Keith can feel his cock moving inside him. Keith certainly feels big enough for that now, big enough to rearrange his guts to make room for his massive cock – for it to show from the outside.

“Fuck, Lance. You’re taking it,” Keith whispers hoarsely, sounding dazed and in awe as he grips his hip tightly with his other hand, driving into him relentlessly and shoving his chest up the wall with every thrust. Lance barely has the cognitive ability to brace his forehead against his forearm so he doesn’t bash his face into the wall.

Lance moans and keens loudly with every thrust, unable to control the sounds falling from lips that could probably be heard halfway across the castleship, completely uncaring who hears them. This is everything he never knew he was missing and more. Someone could stumble upon them right now and he would beg Keith to keep fucking him.

Lance doesn’t realize he’s begging, loud pleading cries of ‘please’ and ‘more’ and ‘oh my god, don’t stop’ until the words are stuttering to a stop and he’s choking on a garbled cry when Keith presses his teeth against his shoulder and bites him, his teeth digging into his skin and holding there. Before Lance knows what’s happening, his cock jerks and he’s spasming in Keith’s arms as he comes so hard, he’s sure he sees a white light at the end of his tunneled vision.

He’s living a religious experience, and Lance is pretty sure Keith’s cock is a gift from God.

Keith fucks him through it, not giving him a moment's respite. If anything, Keith fucks him faster, his hand sliding up his chest to pull him up away from the wall, Keith holding the entirety of his weight with a single hand. Lance tilts his head back to loll against Keith’s shoulder as he pants and groans as Keith fucks into him deeper and harder than before, gripping his hip in a near bruising grip.

“Can you take the rest?” Keith grunts, relaxing his jaw and licking over the bite mark he left behind on Lance’s shoulder that he’s pretty sure is bleeding.

Lance isn’t sure where he finds the words, he hardly has the brain compacity left to remind himself to breathe as Keith’s perfect, enormous cock does its best to knock the breath straight from his lungs with every thrust.

Keith still isn’t all the way inside him, Lance thinks deliriously. He could have sworn Keith bottomed out already, remembers feeling Keith’s hipbones pressed against his ass, but if Keith’s asking if he can take the rest of him then Lance must be mistaken.

“Give it to me,” Lance gasps, struggling to remain upright and relying solely on Keith’s strength to make sure he doesn’t topple over.

Keith pulls out until only the tip of his cock is inside, and he’s moaning – low guttural noises dragged out from deep in his chest – then he pushes back in, and Lance can feel something bulge at the base of Keith’s cock, trying to push past his rim, and that’s not what Lance thought Keith meant.

Mine,” Keith snarls, nipping at his shoulder with too-sharp teeth, reminding Lance how tender his shoulder is becoming. “My mate. Mine. Gonna knot you. Make sure everyone knows your mine.”

“K-Knot?” Lance chokes out, mind spinning, trying to grasp the situation and failing.

“That’s right, baby, my knot. Are you gonna take it, Lance?” Keith growls, grinding his knot against Lance’s rim and causing him to cry out, body shuddering as his rim stretches wider, trying to accommodate the extra girth that’s being offered. “Will you let me breed you and plug you with my knot? I’ll make sure not a single drop leaks from you, fill you up nice and good and make sure it takes.”

Lance can’t make a sound, he can’t, just choked-off gasps and whimpers, and shuddering exhalations as Keith gives up on thrusting in favor of grinding his knot against his entrance, coaxing his rim to give in under the pressure. Keith’s hand trails down his chest to his cock, wrapping his fingers around him with a surprised noise.

He’s hard again.

“You – you fucking love it, don’t you?” Keith purrs, a low chattering sound vibrating against Lance’s back that can’t be mistaken for anything other than pure excitement. “You like the idea of me breeding you.”

Lance whimpers and he barely managed to nod, turning his head so he can mouth at Keith’s neck, feeling Keith’s pulse jump beneath his lips, and when Lance bites down to give Keith a taste of his own medicine, Keith’s hips twist, letting out a ferocious snarl as he grips Lance’s hips tightly as he grinds against him with more determination. Keith’s sharp nails dig into his hips, and Lance winds an arm up to grip the back of Keith’s neck and grips Keith’s forearm with his other hand to keep himself steady.

And oh boy does Lance love it. Loves the ache and the stretch of Keith’s cock forcing his walls to accommodate him, carving a space in his body that’s solely for Keith. Loves the deep-blooming heat Keith’s words and rough thrusts ignite in him; forcing him to yield to his strength. Loves the pressure – the endless fucking pressure – and the sharp pleasure-pain of Keith pushing his knot against his rim. Loves the way Keith sounds and the ways he’s fucking him; unrestrained and feral.

“You’re fucking gagging for it, aren’t you?” Keith continues. “Parading around with a plug up your ass, making sure you’re ready to drop your pants and bend over for me at moments notice like a bitch in heat.”

“Ah, fuck, Keith!” Lance shouts, gasping for breath and clinging to Keith’s arm as Keith strokes his cock and thumbs over the head as Keith’s knot catches on his rim, and slowly, so achingly slow, Keith starts easing it inside.

“I’m going to fill you up so good, Lance,” Keith grunts, panting harshly against the side of his neck. “Such a good omega, gonna knot you and fill you with my kits, breed you full – oh fuck, Lance – so good. You feel so good around me, fuck, I’ll even use your plug to keep it all inside once I’m done with you. Would you like that Lance? Keep you nice and full like a good omega.”

The sound Lance makes in response can only be described as animalistic as he arches almost painfully, spine bowing and his mouth opening in a silent scream, his nails scratching at Keith’s shoulder and clinging to Keith’s wrist that’s still jerking him off as Keith’s next grind has his knot pushing past his rim and sinking inside. Lance wails, trembling so hard his legs threaten to give out when Keith’s knot presses hard and unmoving against his prostate.

Fuck!” Keith whines, hips stuttering against Lance, unable to thrust with his knot locked firmly inside Lance and swelling further. “K-Knees, Lance. On your knees,” Keith moans, high and overwhelmed.

Lance grapples with his jeans to push them further down his legs, movements jerky and desperate. Lance almost cries in relief when he manages to shove it past his knees as Keith lowers them carefully to the floor without separating their bodies.

Oh,” Lance gasps, resting the upper half of his body against the floor, face down and ass up as Keith grasps his hips and pulls it higher, the new angle allowing Keith’s knot to sink further inside. Lance feels Keith’s heated skin against his back where Keith has leaned over him to rest his forehead between his shoulder blades. Lance is glad that he’s not the only one who is overwhelmed.

Keith’s letting out tiny, breathless moans against his skin. Keith can’t thrust anymore, but it doesn’t stop him from rolling his hips and grinding against him like the act of staying still now that his knot is inside him is impossible; it feels too good to stay still.

Lance has similar problems staying still. Lance can feel himself involuntarily clenching down around the girth of Keith’s knot, can feel his walls forced to stretch wider as Keith’s knot rapidly swells bigger and starts to throb, and fuck, every time Keith grinds into him it shifts his knot that much harder against his prostate, and mierda, he’s going to come again.

“You’re so fucking tight,” Keith whimpers, his hands shaking where they’re gripping his hips. “Fuck, Lance, I’m – I’m gonna come. Gonna fill you up. Gonna breed you so good.”

Lance’s loud whine rises into a scream; a mixture of shock and pleasure-pain as Keith grinds into him hard and comes with a shout, sinking his sharp canines into the back of his neck. Lance’s body seizes up, letting out a choked sound as his cock twitches hard, and he comes just like that; completely untouched. Keith’s knot is pressing on his prostate hard enough for Lance to see stars twinkle behind his closed eyelids as his whole body shudders and trembles with the force of his orgasm.

Lance slumps against the floor when Keith unclenches his jaw, groaning when Keith carefully helps maneuver their bodies onto their sides.

“Omega?” Lance pants, trying to steady his breathing and relax but it’s hard when he’s still feeling the aftershocks, a slight tremble still wracking his body. He can’t remember the last time he had come that hard. It felt like his entire body just had an orgasm and not just his cock.

“Sorry,” Keith mumbles against the shell of Lance’s ear, not sounding very apologetic. “It’s a galra thing.”

“And you know that I can’t get pregnant, right? I mean, don’t get me wrong, talking about breeding me full was insanely hot, but – “

“I know that,” Keith groans, hips stuttering. Lance feels Keith’s cock twitch, his knot throbbing as it spurts more come deep inside him, filling him up even more.

“Those new galra instincts of yours are seriously no joke, huh?” Lance laughs breathlessly. “Are you seriously still coming?”

“Mhm,” Keith hums, nuzzling against the back of Lance’s neck and pressing his lips against the bite mark he left there. Lance holds back a wince. Keith must have done a real number on him; it feels like he got mauled – not that he’s complaining but it’s going to be difficult to cover and definitely noticeable, which is probably why Keith did it.

“Wha – the whole time?” Lance says incredulously.

“I’m in rut,” Keith mumbles, trailing his hands down Lance’s body and wrapping his arm around him possessively. “I was trying to stay away from you. I didn’t want to hurt you.”

Lance’s eyebrows furrow, attempting to look over his shoulder to peer at Keith’s face but Keith presses his face further into the crook of his neck so Lance can’t see his face.

“Wait, wait, wait, a rut? Like a dog? Galra go through a mating season? Ay Dios mío, that’s why you’re so riled up and talking about breed – “

“Shut up, Lance,” Keith groans, face heating in embarrassment. “I can’t help it, okay?”

“So, galra have more in common with canines than we originally thought then, huh? But wait, galra look more like humanoid space c – “

“Not a dog, Lance,” Keith grumbles. “And before you say anything, no, not a cat either. But yeah, we go through them once or twice a year.”

“Aw, kitten, why do you have to ruin all my fun?” Lance chuckles, relaxing back against Keith with a sigh. “How long does your knot last?”

Keith mumbles something into his skin that’s too muffled for Lance to hear.

“What?”

“I don’t know,” Keith sighs. “I’ve never… it only happens during a rut and I haven’t spent my last two with anyone. I’d never – I’d never be unfaithful to you, Lance, you know that right? I was always going to come back to you. I’m sorry it took me so long.”

Lance’s heart flutters at the soft and tender words, Keith's voice rough with emotion. Keith’s never been great at talking about his feelings, and it means the world to him whenever he gets a quiet admission from Keith like this.

“I wait too, you know,” Lance says softly, turning his head so he can see Keith over his shoulder. “There’s only ever been you, Keith.”

Keith makes a sound then, a mix between a purr and a growl as he slides his hand to gently curl around Lance’s neck so he can tilt his head to kiss him, even though the angle is awkward.

“I love you,” Keith whispers against Lance’s lips. “I know I don’t say it enough, but I love you.”

“I know. I love you too, and just for the record, next time your galra side comes out to play like this, don’t hide from me. I enjoyed it – immensely,” Lance says, clenching his inner muscles to get his point across.

Keith groans, his hips shoving forward, trying to drive himself in deeper. Lance feels Keith’s cock twitch and throb deep inside him as he spurts another load into him.

“Stop,” Keith says weakly, panting and clinging to him. “At this rate, my knot will never go down.”

“Mm, that’s not quite the threat you want it to be, babe,” Lance chuckles but relents. He can’t imagine how it must feel for Keith to have one big orgasm followed by a bunch of smaller ones for the entire duration that Keith’s knotted. Lance shivers, his cock trying to get hard again just thinking about the pleasure Keith must be experiencing.

“Don’t worry, I’ll keep filling you up,” Keith says huskily, mouthing at the spot behind Lance’s ear, making his cock twitch valiantly in an attempt to get hard, but it only hardens to a small chub. Lance is too exhausted to go again, but he commends his dick for trying anyways.

“Yeah, I can feel that,” Lance laughs breathlessly, placing a hand over his abdomen and swallowing thickly when he can feel a slight bump there; his stomach distended with how much come Keith’s pumping into him.

“Hm?”

“Here,” Lance grabs Keith’s hand and places it over the slight swell of his stomach. Keith freezes for a solid ten seconds before he curls closer, molding himself against Lance’s back, and starts to rub Lance’s stomach reverently, nuzzling into the crook of Lance’s neck and… purring.

“Are you purring? I had a feeling you’d like that,” Lance laughs, closing his eyes with a smile. “It’s nice,” Lance sighs, smiling wider when Keith’s purring grows louder.

A comfortable silence falls as they bask in the afterglow and wait for Keith’s knot to go down, but inevitably, Lance starts to grow restless. The hard floor really isn’t the best place to do this but he can’t regret it when this was literally the best sex he’s ever had – not including their first time, of course, or that one time Keith got jealous and fucked him against a tree when his hands were tied. Lance still owes Nyma a thank you basket for that one.

“How long does it last, anyway?”

“I told you, I don’t know,” Keith mumbles sleepily, clearly exhausted and ready to fall asleep.

“No, I meant your rut,” Lance clarifies.

“Oh, um… usually a week.”

Lance twists his head to look at Keith with wide eyes. “A whole week? You’re telling me you need to fuck me for a whole week?”

“Well, it’s already been four days so… three days left,” Keith admits, cheeks darkening when Lance gapes at him in astonishment. “But don’t feel obligated to – to help me. I have, uh…y’know, my hand. I know you’re probably sore. I wasn’t exactly gentle, so I won’t be upset or anything if you don’t want – “

“No, no, no, no, that wasn’t a complaint!” Lance says loudly. “I don’t care if you have to put me in a pod once this is all over, but I’m not making you use your hand when I’m right here. You need to make up for the two years we haven’t been fucking, you know.”

“Heh, if you say so,” Keith chuckles, hiding a fond smile against the curve of Lance’s shoulder.

“I do,” Lance huffs, gasping when Keith grips his hip and carefully tugs his softened knot free, slowly pulling out of him. “Oh my god,” Lance says, mortified when what feels like a flood of Keith’s come spills down his thighs.

“Sorry,” Keith says regretfully, and he actually sounds apologetic enough that Lance turns over to reassure his boyfriend that he isn’t actually upset, but the words die in his mouth when he sees Keith looking at the floor with an agitated look on his face.

Keith is staring forlornly at the discarded plug. He looks like it’s a damn travesty that using it on Lance is no longer an option because he didn’t have the foresight to not toss it on the floor.

Lance snorts, choking on his laughter. Keith turns towards him with a pout, and it only makes Lance crack up even harder.

“Lance,” Keith glowers.

“Okay, okay, I’m sorry,” Lance laughs, wiping tears from the corner of his eyes. “There’s always a next time, cariño, but right now our bed is calling me – and a hot shower. Definitely a hot shower.”

Keith immediately perks up. “Ours?”

“Mhm,” Lance smiles, carefully sitting up and avoiding the mess they made on the floor, and reaching for Keith. “Take me to bed, Keith – no, no, no, not literally!” Lance yelps when Keith stands with one fluid motion and scoops him into his arms. “I was trying to be romantic!”

“And I’m trying to take care of my mate,” Keith says simply, ignoring Lance’s flailing. “And right now, my mate needs a hot shower and our bed.”

“Mate, huh?” Lance whispers to himself, winding his arms around Keith’s neck and resting his head against his chest as Keith starts down the hallway. Yeah, that’s the perfect word to describe what Keith is to him.

His mate.

Notes:

This idea has been playing around in my head ever since I finished season 6, and thought what if Keith's time in the quantum abyss actually passed in real-time? Can you imagine what everyone must have thought when he disappeared for two years and thought him dead? BIG OW.

Anyways! I hope you all enjoyed reading this! Comments and kudos are much appreciated! I'd love to hear what you think! <3
