i need your discipline

Summary:

Kolivan knew some conflicts couldn't be solved by winning a war and overthrowing an empire. Some problems needed specialized experience; a delicate touch. He wasn’t ignorant to what some of the other Blades got up to in their off time, and while he allowed it to persist, he never explicitly encouraged them.

But Keith was different. Even without a war to fight, the Blades’ work wasn’t over; but Keith operated like he was still on the battlefield, as if something still eroded the boy from the inside. Kolivan needed every Blade in prime condition and swore to assist in any way—as much of an open door policy as he could have.

Kolivan knew some conflicts couldn't be solved by winning a war and overthrowing an empire. Some problems needed specialized experience; a delicate touch. He wasn’t ignorant to what some of the other Blades got up to in their off time, and while he allowed it to persist, he never explicitly encouraged them.

But Keith was different. Even without a war to fight, the Blades’ work wasn’t over; but Keith operated like he was still on the battlefield, as if something still eroded the boy from the inside. Kolivan needed every Blade in prime condition and swore to assist in any way—as much of an open door policy as he could have.

So the first time he'd looked up to find Keith hovering in the door of his chambers, swaying on his feet as if he was still deciding on his next course of action, Kolivan wasn’t exactly shocked.

He bade Keith entrance, of course, and that simple acknowledgement seemed to give Keith the permission he desperately needed. He’d said nothing as he drifted further into the room and sunk to his knees at Kolivan's feet, his eyes pleading.

It was clear the young Blade’s mind was in turmoil. Kolivan had kept his voice soft as he asked, “What do you need, kit?”

Keith’s eyes hooded immediately as if the mere sound of Kolivan’s voice was enough to calm him. “Do you trust me?”

“With my life,” Kolivan said with his full chest. “As well as the lives of the other Blades.”

“Then what I’m about to ask—you know I wouldn’t ask unless it was something I… needed?”

Endless thoughts spiraled in Kolivan’s mind as he leaned forward in his chair. “Tell me what's on your mind, kit.”

He’d never seen Keith look more certain when he replied, “I want you to hurt me.”

That was how it started. Kolivan hadn't even known what to do at the time, but Keith knew what he wanted enough to instruct Kolivan on the basics.

Now when Keith comes to him, he closes the door to Kolivan’s quarters and kneels at his feet until he's acknowledged. Kolivan is usually skimming scouting reports or catching up on briefings, knowing well enough now that Keith usually needs a few minutes to relax and get into the right headspace.

When he senses Keith is ready, Kolivan sets aside his task and leans back in his hefty, armed chair, patting his lap. “Come.”

Keith crawls across the floor and into Kolivan’s lap, arranging himself across the armrests so his rear sticks up. Kolivan easily releases the seals of the Blade uniform and tugs the lower half down, baring Keith’s ass.

“Count for me, kit.”

Keith hardly reacts to the first slap, his tone perfectly composed when he says, “One.”

His voice cracks a little at ten; by twenty, he’s breathing heavy and gripping the armrest. But Kolivan is well-versed in knowing when to stop, and they’re far from finished.

“T-twenty-one.”

Keith’s ass is rosy, cheeks darkening each time Kolivan brings down his broad hand. He notices that Keith’s legs are drifting wider apart and he doesn’t exactly mean to peek when he catches the sight of Keith’s cunt, glistening within the dark shadow of his leggings. He’s long since believed that if Keith derives pleasure from this arrangement, that’s his business, but now that he’s laid his eyes on the evidence, it’s impossible to ignore.

After the next slap, Kolivan waits, listening to Keith’s labored breathing before his hand slips between Keith’s thighs.

Keith jerks but remains over his lap, nostrils flaring.

Kolivan’s palm is wrapped around Keith’s thigh, but he lets his thumb trail closer to Keith’s heated cunt as he asks, “Do you need assistance with this, kit?”

Keith whimpers and nods, legs parting against the stretchy material of his uniform leggings. Kolivan hums deep as he traces Keith’s slit, seeking the hard nub of his cock.

“You should have asked sooner,” Kolivan rumbles.

“M’sorry,” Keith says. “I didn’t—nng—know if it was—ah—appropriate.”

Kolivan can’t help but chuckle at that, stroking Keith’s cock with his thick fingers. “I promised I’d look after you, didn’t I?”

He hears Keith’s throat click as he gulps. “Yes, sir.”

Kolivan pulls his hand away, tugging Keith’s leggings down to his ankles. He adjusts Keith to lay more comfortably across his lap, less in a position of presentation. He rubs the backs of Keith’s thighs as he encourages his legs to spread. “You’ve needed this for a while, haven’t you?” he asks quietly.

“Yes, sir,” Keith whispers after a moment.

“You didn’t want to ask another Blade to assist?”

Keith lowers his head at that and it’s all the answer Kolivan really needs, but he wants to hear Keith say it. He cups one cheek of his ass as gentle encouragement. “They see you as one of them, kit,” he says. “You should not be ashamed to seek them out when you need companionship. I strongly doubt any of them would turn you away.”

“It’s not—” Keith gulps. “It’s not that.” He props himself up, bent elbows against the armrest as he looks over his shoulder. His eyes are sharp, full of the determined spirit Kolivan admires most about the half Galra. “They’re not you.”

Laughter doesn’t come naturally to the leader of the Blades, but he is amused nonetheless; to think that there are Blades closer in age and stamina to Keith yet he carries a clear preference for Kolivan is… intriguing. “You flatter me, kit.”

Keith blushes, the brief shame in his eyes fading into something darker. “It’s not that I don’t trust them,” he says quickly. “They’re my brothers now, always will be. It’s just… different with you.” His lashes flutter as he chews on his lip. “Is that okay?”

Kolivan lets his warm smile spread, content that Keith may be the only other person to see it. “Of course it is.” He slides a hand up Keith’s back. “Now relax, and let me take care of you.”

Keith’s sigh is one of relief as he settles on his stomach. Kolivan caresses his reddened ass, soothing the tender skin before his long fingers trail between Keith’s legs again. He smears Keith’s slick with the rough pads of his fingers, once again stroking his cock as Keith moans softly against the armrest.

He knows this isn’t about his own pleasure, but Keith’s noises, the way he writhes across Kolivan’s lap, leaves the Blade leader feeling stiff in his uniform. And though it’ll be an easy thing to take care of once he’s satisfied Keith and sends the boy on his way, his thoughts can’t help but drift. He pictures Keith lying beneath him, making those same sounds but louder as Kolivan takes him apart. The thought sends a wave of possessiveness through him, and he shouldn’t concern himself with Keith’s prior sexual engagements, but this entire situation leaves him wondering if anyone has ever managed to satisfy Keith’s true urges—his needs.

Keith grinds urgently against Kolivan’s fingers, whimpering into his folded arms. Kolivan trails from Keith’s hard cock to his dripping hole, rimming the opening as he murmurs, “Do you need me to fill you up, kit?”

Yes,” Keith gasps, his ass jerking into the air. “P-please.”

Kolivan allows a chuckle, tracing another teasing circle around Keith’s hole before slipping a finger inside. Warmth clenches around his knuckles and it’s only natural for him to imagine the same feeling around his cock. He growls without thinking, his instincts kicked up like a dust storm.

Keith freezes, sending a panicked look over his shoulder. Kolivan realizes his misstep and takes a heavy breath, rubbing Keith’s lower back with his other hand. “Apologies.”

“Are you okay?” Keith asks.

“I am fine,” Kolivan replies. “This is for your benefit. I should not give in to my urges.”

Keith hesitates and Kolivan can see the thoughts zipping through his brain behind his hardened indigo eyes. Then Keith grabs Kolivan’s wrist and pulls his hand away, pushing himself to his knees so he can straddle Kolivan’s lap.

“Kit,” Kolivan asks softly. “What are you doing?”

“You’ve helped me all this time without asking for anything in return,” Keith says, laying his hands on Kolivan’s broad shoulders.

“That is the arrangement we agreed upon.”

Keith shrugs. “So? Change it.”

Kolivan sighs through his nose.

“The others, they’ve… told me about Galra stuff,” Keith says. “I know what I’m asking for; I’m not stupid.”

“You are not,” Kolivan agrees, unable to keep his hands from running up Keith’s thighs. “But are you sure this is what you want? That I’m who you want?”

Keith leans closer, his breath puffing warmth over Kolivan’s ear. “I want you to fuck me, sir.”

Another growl rumbles from Kolivan’s chest as he reaches between them to unclasp his uniform leggings. He rolls his cock out, letting it slap against Keith’s stomach. He’s tempted to laugh when Keith’s eyes widen, but he just cups a hand under Keith’s ass and holds him close. “Too much for you, kit?”

Keith snaps out of it and shakes his head. “No. I’m ready.” He takes Kolivan’s cock in both hands, thumbs notching under the flared tip. “Could’ve warned me, though,” he mutters.

“We can stop at any time,” Kolivan reminds him.

Keith smirks at that, his hands absently mapping Kolivan’s length. “Don’t worry, I can take it,” he says, more arrogant than confident.

Then he folds himself in half and sinks down, closing his lips around the tip of Kolivan’s cock.

It isn’t what Kolivan had in mind but he’s not about to stop the boy from taking what he wants. His hands curl around the armrests of his chair as Keith suckles the spongy head of his cock, poking his small tongue into Kolivan’s slit before he laps lower.

Then Keith takes him in his mouth, tirelessly working his way down until Kolivan is certain his cock is touching the back of the boy’s throat. He lets out a ragged sigh, catching Keith’s long braid to weave it between his fingers.

Keith jerks the lower half of Kolivan’s cock as he slicks the top half with saliva, bobbing his head before he pulls off to lavish attention over the tip. Kolivan grunts, his instincts slowly overtaking his rational thought as Keith worships him with his deft tongue and warm mouth. He tugs on Keith’s braid when he feels his knot swelling, causing Keith to snap to attention.

“Ride me, kit,” Kolivan commands.

Keith’s face is flushed and spit-slick, but he nods as he lifts up on his knees. “Y-yes, sir.” He crowds against Kolivan’s chest, lifting his ass high in the air as he positions Kolivan’s cock with one hand.

They both groan as it slides against Keith’s wet cunt. Kolivan cups Keith’s ass and spreads him, the tip of his cock pressing against soft but firm flesh before it plunges into incredible warmth as Keith lowers himself.

Keith buries his head against Kolivan’s neck, whimpering but not halting his descent. Kolivan keeps him spread open, fingers digging into Keith’s ass.

“That’s it,” Kolivan murmurs, brushing his furry cheek against Keith’s hair as a possessive purr rattles through his chest. “Perfect, little kit. Just take me nice and slow.”

He feels the needle scrape of teeth at his throat, responding with another low growl; Keith’s Galra side is slowly being coaxed out, bit by agonizing bit. Kolivan has only seen it in the heat of battle, never like this, and it makes his body and mind burn with the urge to claim. But he’s still lucid enough to know that he has to let Keith lead, to allow the kit to remain in control or he could break the trust they’ve built for years.

When Keith has taken half of Kolivan’s cock, he pauses, inhaling deep against Kolivan’s neck. Kolivan strokes as much of Keith’s body as he can reach, cupping his thighs and his hips, tracing circles across his back. “Take your time, little one. You’re doing so well.”

“Can you…” Keith nuzzles up his throat, pressing his smooth cheek into Kolivan’s fur. “Spank me?”

Kolivan inhales sharply. “That’s what you want?” he asks, hands drifting down Keith’s spine.

Keith nods and buries his face again. “Please.”

Kolivan cups the round swell of Keith’s ass, easily eclipsed by his large hands, and lands one smack on the left side. As Keith moans, Kolivan echoes the sound as Keith’s muscles contract around his cock.

“More,” Keith mumbles.

Unable to resist acquiescing, Kolivan spanks him again, three smacks on the right side this time. Keith is panting and starting to roll his hips, sinking further down Kolivan’s cock. The slide is tight, blissful; a pleasure Kolivan can’t remember the last time he felt.

Keith steadily begins to ride him, arms closing around Kolivan’s thick neck to support his motions. Kolivan continues spanking him at random intervals, his noises growing louder each time Keith’s cunt squeezes around his cock. Keith is panting against him, sweat soaking through his uniform.

Kolivan stills him with a stiff grip on his thighs, then tugs the uniform top over Keith’s head. Keith’s chest is a battleground of scars that Kolivan is tempted to trace with his fingers, his tongue, but mostly he wants Keith comfortable. “There,” he breathes, hands returning to Keith’s ass. “I want to see all of you when you come for me, kit.”

Keith’s breath hitches into a moan as he continues bouncing on Kolivan’s cock. Kolivan’s hands on his hips aid his rhythm, guiding Keith up and down without forcing him. He’s impressed that Keith has nearly taken his full length, deserving of its own reward.

“Touch me,” Keith says. “I’m—I’m so close, please.”

Kolivan hums as he seeks Keith’s cock with his thumb, giving Keith plenty of friction to rub against. Keith mewls, insides spasming as he speeds up. Kolivan spreads his ass with his other hand, fingers drifting to the hot center where his cock is plunging in and out of Keith’s slippery hole.

“Look at you falling apart on my cock.” Kolivan circles his thumb, working the hood of Keith’s cock over his sensitive nerve-endings.

Keith sputters through a moan, likely not expecting Kolivan to be so blunt. “Fuck—fuck, it feels so good—nng—”

“No one else can take care of you like this, can they?”

Keith shakes his head as he pants. “N-no, I only need you.”

“Good boy,” Kolivan says, thumb working faster at the base of Keith’s cock as he wraps Keith’s braid around his other hand. “Come for me, little kit.”

Keith’s lower half shifts as he rocks against Kolivan’s thumb, his moans increasing in volume as he mounts his climax. Kolivan sees the Galra come out in him—patchy fur sprouting along his jaw, canines elongating into fangs. His eyes pop open to reveal cloudy, yellowed sclera as his final shout indicates his orgasm.

Then Kolivan feels it—warm fluid spilling into his lap, pooling on the seat beneath them, as Keith squirts hard on his cock. The surprised shame on Keith’s face coupled with the gush of fluid sends Kolivan’s base instincts into overdrive. If he wasn’t so close himself, he’d have carried Keith to the nearby bed to fuck him senseless. Instead he clamps his large hands around Keith’s sweat-slick sides and violently snaps his hips, burying the last inch of his cock up to his knot deep inside the young Blade.

Keith whimpers, clawing uselessly at Kolivan’s chest, trying to gain purchase as Kolivan jostles him up and down. The growl that comes out of Kolivan is almost a roar as he manhandles Keith’s body on his cock like he weighs nothing. Keith moans like he’s still riding the throes of ecstasy, pleading with Kolivan to fuck him harder.

“You want me to come inside you, little kit?” Kolivan purrs. “Knot you and fill you up with my seed?”

“Y-yes—please—”

“Say you’re mine.”

“I’m yours—only yours!”

Kolivan pulls Keith down hard, his knot breaching the tight clutch of his cunt. He shouts, surprise halved with pleasure, as his knot pops. He cages Keith’s body with his arms, holding him close as he feels himself empty out.

Keith sighs against his chest, settling himself like he knows he’s got time to spare. Kolivan finds himself seeking Keith’s braid, a comforting, protective measure that keeps him grounded. “Are you with me, kit?” he murmurs.

“Mhm.”

Kolivan dips his head, pressing his face in Keith’s hair to inhale him—sweat and musk and something vaguely citrusy that reminds Kolivan of herbal tea. “Did you get what you needed?”

“Uh, yeah, I think so.” Keith chuckles, then wriggles his hips as much as he can with Kolivan’s knot still embedded inside him. “Um, how long until…”

“A quarter varga,” Kolivan responds. “Hopefully.”

Keith chuffs. “Hopefully.”

Kolivan raises a brow, still reveling in post-orgasm haze and the way Keith’s scent fills his nostrils. “You have somewhere you need to be, kit?”

Keith glances up the planes of Kolivan’s chest, a soft smile on his lips. “No, sir. I’m good right here.”
