The plan is that he'll lubricate Light's dick before Light slams it into his ass.
Light is convinced that it is a thrilling arrangement. For Light, it might be; L doesn't care enough to argue - his mind wanders, revising his latest back-of-the-envelope calculation. One blowjob is a small price to pay for Light to fuck off for a moment. Light is easier to trip when he is satisfied. And it's not as if they hadn't tried it before - just not as a centrepiece of the morning.
L's knees are spread wide on the floor. He is confident in this pose - even if Light tries to, Light won't manage to drag him around. L obediently opens his mouth, pulls out his tongue, and glances at Light with big eyes, with feigned reverence transparent enough to get Light's nose to momentarily twitch in anger.
Unfortunately, the view of L kneeling with his face adorned with a pretence of a worshipper allegedly still does it for Light. Hence, they proceed.
Light cards his fingers through L's hair, gaze fierce and dark. L answers in kind. Kira gets off on being observed? Let him feel the weight of L's aggravation and judgment.
L permits Light, holding L's hair, leisurely pull his mouth down on Light's dick. L seals his lips around it, feeling warm, salty weight settle into his mouth, and looks up at Light, awaiting an order. Light's eyes are slowly turning wild. Cruel.
"Suck," he says with palpable malice, finishing off the cocktail of emotions. For L, it always tastes sour.
L lowers his eyelids and starts doing just that, slowly and deeply, sliding the relaxed ring of his lips up and down. He feels the weight grow, the dick swell, the warmth turn heated. It presses his tongue down, but he doesn't try to lick or swirl it – he has no appetite for that, so he'll just keep following the directions. Time flows unhurriedly, and, instinctively, he starts breathing through his nose, his mouth dedicated solely to sucking, filling himself with Light's dick.
Above him, Light exhales harder. L keeps going, chasing thoughts away.
At some point, he shifts on his knees slightly, disliking the hardness of the floor. Time flows, and the floor does not get any more comfortable. L changes his ankles' position, moving a bit closer to the bed, to Light. And takes Light's dick a bit deeper into his mouth. Not quite... knowing why. Although, it feels alright. Perhaps he's gotten used to it and is not feeling any difference between five minutes and five seconds ago. Since he is sitting here anyway, might as well make it engaging. At his languid yet confident work, Light groans in pleasure, and L automatically exhales, too, feeling an erection throb in his mouth, pleasantly hot. It tingles.
The entertainment between L's cheeks makes his mind grow quieter. His mouth gets filled with precum. Bizarrely... pleasant. In fact, humiliating pleasant, to the point of him starting to salivate at it. He is annoyed at not understanding, so he runs through the rare vocabulary in his mind. There is only one logical fit that he can find.
Oral fixation? Is that what this is? Ugh. He should've known about it. But he's never thought to try and find out.
He doesn't notice when his focus starts slowly narrowing down. His knees spread ever so slightly out of some instinct rather than conscious desire. Then his chest leans onto the edge of the bed, then his lips loosen, and his jaw slackens, and, before he knows it, he is carefully getting his throat around Light's dick.
It makes zero sense. It means less contact with more sensitive areas of his mouth, but L is already breathing through his nose, swallowing lightly, and he doesn't sense the gag reflex kicking in because of how slow he is rocking closer and further, further and closer. Perhaps he is just... getting bored? He could be pulled on the object just a touch more...
Light's breathing is speeding up, and L doesn't need to watch him to know that there is a shadow of shock in Kira's burning eyes.
"Good boy. Very good," Light eventually says quietly, visibly disbelieving at himself uttering those words, the words which L also dislikes. Good boy. Right. Light is pleasantly surprised, a growing smirk heard in his voice, and his thumb teasingly pets L's cheek, where the skin is stretched by L relaxing his jaw. Light's other hand comes up to pet L's other cheek until Light is holding his knuckles on both sides of L's face, for L to rub against as he is trying to take the dick in deeper, while not letting it out much whenever L has to pull away to ensure movement. Better finish this off quicker, so he doesn't feel this oddly for much longer. "Who knew you'd be fantastic at this."
L disregards him completely. Light can go choke, for all L cares. L is getting tired of sitting upright, for some reason, so he leans and takes in a bit more before realizing it feels like it stifles any reflexive attempt to breathe a fraction of air through his throat. It becomes harder to swallow, and he, not even hearing himself, lets out a dissatisfied moan.
Light almost laughs, then shushes him mockingly, sneering more apparent: "I know you want more. I won't let you go hungry."
L feels weird. As if aching. Not understanding how, where, or what for. He moans more, somewhat more aggressive, somewhat more... needy?
Slightly dizzy...
A hand captures his jaw.
His movements halt, and, for a short moment, he is stuck there, tingling lips, dripping tongue, half-drawn on Light's dick. L sneers to the best of his ability and pushes to move, but Light rubs his cheekbones and holds him steadily and firmly.
L feels himself shaking. From dissatisfaction? Anger? His attention snaps to this fact for the first time. He snaps his gaze to Light, unable to fight or articulate his growing hostility, growing itchiness. Something reminiscent of understanding is painted all over Light's face, a smirk calmer, observant.
"Shush," Light says velvety. "I've got you. Do it slowly, and then stay here."
Gentle fingers beckon him closer by his jaw, and he gradually sinks down, feeling more heat, weight, everything… more. Light helps him keep going and not shake until Light's dick is inches away from being fully sheathed. L can barely moan through it, and his throat slowly spasms at halted yet moderately successful attempts to swallow. Light curses above him, words coming out breathily.
"Enough," Light says. "Stay."
L attempts to move closer. Light holds his face. "Stay. Relax."
He stays, eyes slowly starting to burn. With every passing second, he is feeling increasingly like he will begin to shudder soon.
"Wait," Light says, catching the tip of his tongue with two fingers. L stays, as he's been told.
Light's thumb brushes his bottom lip, his top lip, dips in beside Light's dick, and rubs the inner side of L's lip. L moans with a bit less discomfort.
And then Light slowly and very carefully pushes two fingers under his dick and over L's tongue, pressing it down, and, immediately, gently rubs. Pleasure soaks L's mouth, and he shivers violently, amazingly, feeling little to no space left to occupy inside.
Light seems to wait for a moment, but L just pants harder, eyes closed at comforting sensations, fewer sounds escaping him. Light adds one more finger, petting him, and L feels like he might black out.
The bliss lasts for a minute, or a few minutes, or however much time, before he feels the need to feel more, to move down. Light stops him.
"Slow down," Light says, audibly trying to steady his voice and not pant. "Let's breathe."
It takes Light's firm hold, but they breathe for a bit. L keeps quietly moaning, shivering, anger and confusion mudding his senses, feeling as if he does not quite understand what is happening.
"Alright," Light says. "I think this might've been… a lot."
L growls from a need so deep that he aches.
"...Fuck. Okay. Alright. Pull away a bit and suck."
Time stretches.
L tries to chase away the fog flooding his mind.
"L? Can you hear me? Are you... alright?"
L closes his eyes.
Light says, quiet, angry, "Fuck”.
Light has to grip his hair and pull him away, to his confused moan. The fog is not dissipating. The thoughts and feelings are bundled into a multi-sensation mix of pleasure rubbing on his tongue, caressing the insides of his cheeks, teasing the roof and pressing lightly on the back of his throat. It is not enough. L is painfully dizzy, unspeakably weak, ready to tear him apart. Light doesn't do anything for a long moment, a series of moments, and L is only feeling worse, head spinning like he might faint with every passing second.
Light eventually takes control and starts slowly, deeply fucking his mouth, verbally stopping him from deciding things himself. It makes him feel even less conscious, but pleasure relaxes him and draws him in instead of fanning the hunger and ache in his body. He moans, squeezes Light's thighs with an iron grip, and feels himself move his hips to create friction of denim pressing to his dick between his spread knees. Light is breathing raggedly, wiping the sweat off L's face with the other hand, and Light's thrusts are measured and rhythmic, not giving too much or taking too little.
Light comes; L swallows, mind hazy, and persistently kisses his dick, despite Light trying weakly to pull him away. Realizing how hot and tense L's body runs, Light somehow gets him off his knees and onto the bed. Only Light can't get him to lie down in any manner; their strength is still too evenly matched.
L pushes Light down. Light fights, alarmed, not realizing it's a losing game.
L traps him.
"Stop," Light whispers, tense. Light is captured beneath him, L's legs pressing down Light's arms, L looking down at him. "Stop," Light says, straining, failing to get his arms from under L's legs. "Stop," Light's expression is taut, and his nails uselessly, ferociously dig into L's arms. L finally encircles Light's wrist with his fingers and squeezes it until it hurts, forcing Light to give it to L.
L pulls Light's fingers into his mouth. Light acquiesces.
After a while, Light hesitantly, gently rubs L's tongue, trying to keep up the same soothing rhythm.
It seems to work, so Light somehow crawls out from under him and carefully pushes his other hand under the band of L's pants, and L almost screams and then almost hits him from how intensely the pleasure hits. Light jerks to caress his stomach, which makes L shake all the same, but at least it does not make him lose his sanity. Light eventually softly strokes his dick through denim, just with a touch of fingertips, feather-light, insistent circles, moving around and breaking the pattern.
The piece of L's memory feels… absent. He comprehends reality with Light hovering undressed over him, both under a blanket. Light is almost lying down on top of his own naked body. Light seems to be breathing into his chest, head bowed. L frowns weakly at not being able to string two sentences together. Light exhales shakily and kisses his collarbone. L exhales. Light seems to force himself to move up and starts licking L's neck, tongue wide and tired. L feels his eyelids grow heavier, muscles feeling softer, warmth melting him.
L wakes up again. It is as if he blinks, and the picture pulls itself back together. Light is looking at him, hovering over him, bare skin warm to bare skin. Light's brown eyes are edgy, calculating, cautious.
"What is going on," L asks hoarsely, barely able to find his voice.
"Everything is alright," Light says with a measured tone, and if L didn't know that the person in front of him is a master manipulator, L would believe it.
"Why do I feel half-dead," L deadpans.
"I think you'll remember in a moment," Light responds, his face barely noticeably taut. "Now, I have a question. If I leave you here for five minutes and get you water – will you stay in bed?"
L doesn't comprehend what he is talking about.
Why would L not stay in bed?
"L?" Light asks almost… carefully? But his eyes are narrow, and his face is all… Kira.
"Yes."
"What will you do if I leave for five minutes?"
L feels familiar annoyance.
"Stay in bed," he says coldly.
Light watches him for one long moment.
"Alright," he pulls away slowly, leaving from under the blanket and pulling it back to cover L. "I'll be back."
L exhales. His chest is cold. His eyes are tired. His body feels weird and… overly saturated with feelings.
He tries to remember what's going on.
