"No, that isn't quite right."
L's voice is muffled slightly where he leans too close to the screens in front of him, eyes scanning information faster than any of the others can even realize that he's seen something they haven't. As usualâŠ
They'll get used to it eventually, just like you did. But you aren't paying much attention, not in totality anyway. Soft taps of the spoon against the ceramic cup in your hand break the silence before he does, jarring and unapologetic.
"Whatever Kira is doing isn't just⊠thank you⊠It isn't just coincidence."
He pauses to speak to you when you hand him his tea, decaf, upon your request. His thanks gentler than the rest, genuine and kind. As much as he's willing to show in front of the rest of the team at least.
"He is testing me."
"Or he's just killing at random, because he has some bullshit god complex."
Aizawa. You don't think he's entirely meaning to be contrary, but he is⊠All signs point to a face off between the detective and the killer, and yet he refuses it outright in favour of something that seems more reasonable. Kira is not reasonable, regardless of the lives he takes, there's a purpose for each one. A message.
"Perhaps."
L's voice is as calm as ever while he stares at the monitor, not even taking a small glance in your direction when you sink to the couch by his side with a smile up at Mr Yagami when he moves out of your way, distrustful of you but not enough to cause a fuss over your sudden appearance in their team.
You don't know fully what your boyfriend told them, whether he even mentioned that you were dating or not⊠so you keep it close to your chest, follow orders. Stay unassuming. Even if you want to speak to L about anything, literally anything but the damn case.
"Thoughts?" The low question breaks you out of your uninterested inspection of the footage between you, his lidded eyes flitting over your expression as he examines every emotion you could be feeling with a honed precision. "Do you think that he's killing at random?"
"I'm not a detective, Ryuzaki."
"I asked for your opinion, not your credentials."
The tease gets the attention of the rest of the team immediately, silence falling faster than a pin could drop into the plush, cheap carpet lining the floor. You can feel the lingering stare of the men behind you when you sigh, leaning into the couch with a small lick of your lips to wet them before you turn your head to face him, your gaze not leaving the monitor.
"It's too obvious, half of the kills feel more like he's proving that he can do it rather than to actually kill them. Like a goadâŠ"
You pause for a breath when your eyes break from the screen, catching his intense stare with a fierceness of your own that makes his lips curl up into a faint smirk. Proud.
"There's nothing random about the things he's doing, the time, the people⊠it's all planned out to the last minute detail."
"Hm⊠Perhaps you are Kira after all."
"Shut upâŠ"
You almost forget yourself before sitting up straighter, not reaching out to nudge him like you wanted to even if you don't think he would mind⊠mostly. But you know he has a reputation to uphold regardless of the trust he holds for the team gawking at the both of you as if you'd outright said you were Kira.
Hell, they might have reacted less if you had.
"If you're done staring, I'd like one of you to look through every criminal in a 200 mile radius, not shown to the public, that has died in the same way as the others."
"Right, sorry, Ryuzaki. Is there anything else that we should be looking for?"
It's Soichiro that answers first, hesitant and confused at the sudden shift in the tension, eyes darting between the both of you as L takes a long sip of his tea with a content hum. Not speaking for a long moment while he thinks, slower than he usually does. You were right. He is struggling to pay attention with you by his side, his thigh pressing against your own lazily, unintentional even if he was the one to move closer when you dropped next to him.
"Actually, yes. See if we can get the footage from the store across the street where the group of bikers were killed, all three if they'll give it to usâŠ"
You shoot a quick glance in his direction when he pauses before a blush rises to your cheeks, his eyes already focused completely on you through the dark hair falling across his vision. Distracted. Hungry. He looks like he's seconds from devouring you where you sit, even when his voice doesn't waver.
"And the café on the corner... I believe that is all."
Minutes stretch into hours quickly as you watch L work by your side, occasionally asking for your input with a soft question, but mostly just rambling towards you to keep his mind on track while knowing you're listening with an adoring expression long before he looks over to you. The light dims when the clouds swallow the sunset, the faintest brush of fingers against your thigh making you jerk in shock from your bored stare past the screen.
You barely get the chance to peek towards him before his lips press firmly against your own, sweet and urgent for a lingering second before he breaks the kiss, his hand curling around your jaw with a shaky exhale. And then he moves away, leaving you dazed and wide eyed as the door clicks back open and Matsuda walks in, Yagami in tow while they talk about something you don't care to listen to, instead finding a deep interest in the spoon resting on top of the empty plate in front of L.
"⊠of them didn't want to 'incur the wrath of Kira.' and it's only going to get worse the longer this is allowed to continue."
"Yes, unfortunately this was bound to happen." L's voice makes you peer back up as he answers the men behind, his tone laced with indifference even if you can feel the light buzz in his body by your side. "Thank you⊠you can all head home for the day."
"Already?⊠Are you sure, Ryuzaki?"
L doesn't smile. Doesn't change the limber coating his words as he speaks again, eyes focused forward on the same footage that he's been staring at for the majority of the day. Uninterested and entirely distracted with the taste of you lingering on his tongue.
"Yes. I am." There's a brief pause when his eyes drop to the plate below him, reaching out with a lazy swipe of his finger to catch a bead of stray frosting and licking it off, holding your eye contact, carefully to avoid suspicion. "Rest up tonight, it's only a matter of time before none of us have the time to."
"He has a point, thank you, Ryuzaki⊠Y/N."
"Be safe..." Your gentle goodbye is cut off with a small squeeze of your thigh as they trickle out of the door, their eyes completely off of L's sudden interest in you. "Sleep well."
The door barely clicks shut before he's on you again, dropping to his knees on the soft leather to push you back into the cushions with a hum, your lips pressing against his in a fervor that he can taste dripping off of your tongue. It's desperate, as if he's been waiting all day for the second he got you alone⊠and you wouldn't be wrong in that regard.
"Bedroom."
"RyuâŠ" You hesitate for a second when he pulls away, eyes wide and pupils blown so large you can hardly see his irises as he stares down at your fluster with a rare smirk. "Are you sure?"
He doesn't answer, not with words.
His head tilts with a look that tells you every thought in his fogging mind. Cold fingers curl into your own when he moves to stand, practically dragging you up to follow him. Quick and so very pitiful when he turns on the balls of his feet and pulls you into the bedroom, hurriedly caressing your body to undress you with shaking hands. Urgent and so unlike him to lose his composure so easily.
"I⊠I know I asked you toâŠ"
Saliva pools into his mouth at the thought of you riding his face, tongue buried so deep inside of you while you use him for your own pleasure.
He swallows, nervous even if his eyes trail down to your exposed chest, the fabric of your shirt falling to the floor as your fingers undo your pants with a soft look, waiting for him to keep speaking.
"I'd like to fuck you instead, if that'sâŠ" His brows knit together for a second before tugging you into him, noses brushing gently before he steals a soft, near worshiping kiss from you. "I can't think⊠I need to get back to work."
"Mm, not a chance⊠you're staying with me after, understand?"
Mussed, dark hair shifts when he nods immediately, letting you guide him towards the bed with deft hands as you undress him with a sweet grin, quickly pulling his sweater over his head to toss it onto the floor, followed by his pants and underwear.
"Condom?"
"I⊠right, yes."
A faint, pink blush settles high on his cheekbones when he moves away from you, watching for a fleeting moment while you move back onto the bed, legs spreading as if you're trying to distract him⊠And you absolutely are, he knows you.
"You're beautiful."
He's never been shy with his praise. Even if he feels out of place giving it he would never hide his adoration to you, every single inch of you is perfect to him, and he will happily spend the rest of his life proving that he's right about it. As if you could have a chance of proving him wrong in the first place, even now.
A small bead of pre-cum drips down his length when he pauses, tentatively crawling onto the bed and settling back on his calves to open the condom with trembling fingers. It's not the first time you've had sex, not by far⊠but he gets anxious before each time regardless, the worry of not performing well choking him faster than his lust can force it to slip from his mind.
"L, breathe⊠here, give." The cool foil rests between your fingers as you open the packet and part your thighs for him to come closer. "Get out of that pretty head, I love you."
His head falls onto your shoulder with a gasp when he kneels flush between your parted legs, your hand wrapping around his cock with slow pumps that claw his worry from him forcefully and leave him struggling to speak. The cold feeling of the latex makes him jerk slightly in shock as you roll the condom onto his length slowly, your voice dipping low into his ear.
"I've missed youâŠ"
"I l..love you, I don't think I'llâŠ" Last. You know what he's going to say before he gets the chance to when your leg hooks around his waist, nudging him closer as the tip of his cock rubs slowly through your dripping folds. "I want to make you cum."
"Don't hold back, L⊠if you cum, you can just do what you wanted, hmm?"
His head snaps up at your tease with wide eyes, realizing with a hiss that you're right. Even if he doesn't make you finish with him, he can claw you over the edge in a hundred different ways without ever fucking you. Your reassurance makes him shiver, his lips parting in pleasure when he jerks weakly into your entrance, soaked and squeezing the tip so perfectly.
The sudden stretch of his cock makes your head fall back with a whine, slow strokes of his length pulling you into a blissful daze as he sinks further into you, patient and careful. No matter how desperate he is, he would never risk snapping his hips forward and filling you in one devastating thrust.
Even if he thinks about doing so⊠more than he wants to tell you.
"I'm⊠s..stop looking at me like that."
A sweet laugh pools in your throat when he covers your eyes with a lazy hand, his cock twitching inside of you with every sudden clench of your tight walls around him, hugging him so perfectly that even with the layer between you he's left too close to think.
Small, warm exhales linger against your flushed skin when you curl your fingers into his hair, massaging his scalp tenderly while he gets his breath back enough to be able to move.
With a quick, tentative jerk of his hips he sinks in fully, groaning in your ear while he grips your thigh so hard you know there'll be small bruises blooming on the skin by morning, not that you entirely mind when he's grinding down into you like it'll kill him if he stops. And with each breathy moan that falls from parted lips, you don't think he has any intention of stopping.
"Not⊠KiraâŠ"
"You're sure?" Your teasing question makes his head fall onto your shoulder, pulling out almost entirely before sinking back in, slowly but no less devastating when he fills you so wonderfully. "G..good, fuck it's⊠so good."
"0 per..cent ⊠Need you."
"You have me, L⊠I'm right h..here, take what you want from me."
You regret the reassurance near instantly when his head tilts up to press his lips to yours, his thrusts slipping from a slow, calm tease, straight into unalloyed desperation. Hard. Fast. So deep that you can feel every nudge against your g-spot when he tugs your leg around his waist with a muffled whimper, completely swallowed by you.
"N..not gonna⊠last."
"I don't⊠care, I love you."
Darkened eyes roll back in his head when he breaks the kiss completely, lips still brushing against your own as gasps fall freely from him, whiny and too close to care how pathetic he must look, pinning you down to chase his own pleasure even if it claws you with him.
"Touch⊠touch yourself, please?"
You can't ignore his plea even if it was something you wanted to, your hand dropping between you to rub slow, tight circles against your clit as he entwines his fingers into your other. A small grin curls onto his lips when your back arches into him through your bliss, head falling back into the pillows and giving him unrestricted access to the column of your throat.
"You're⊠incredible."
It's muffled into your skin while he leaves wet kisses against your neck, eyes fluttering shut with a whimper when you spasm around him at the sound of his breathless praise, clawing him ever closer before he can care to slow his thrusts. And he doesn't. Not when you're moaning so sweetly under him as you fall apart, all because of him.
All for him.
"Y/N, n..need you to cum first."
"So⊠closeâŠ"
Your fingers speed up against your sensitive clit when his thrusts falter, moan breaking in his throat when you clench hard around him, tight, fast pulses forcing him to ride the edge painfully to make you finish first.
And you do.
Your mouth falls open in a loud, breathy cry when he sinks his teeth into your shoulder, not hard enough to bleed, but it throws you into your orgasm before you can bring yourself to speak, tensing hard around his poor, sensitive cock and clawing him down with you.
"F..fuck, tightâŠ"
Desperation laces every movement when his hips stutter to almost a stop, weakly thrusting into your tight, fluttering walls as he fills the condom in long, hot spurts of cum, wishing more than anything that it was inside of your dripping core instead. A low grunt shatters in his throat when you fall limp onto the bed with a shaky exhale, wrapping your legs around his waist to guide him to chase his pleasure with every slow grind into you. Even if he collapses on top of you quickly with a pathetic whine, soft and exhausted.
Neither of you move for a long, blissful moment while you bask in the loving touch of each other. Your nails graze his scalp lightly as he peppers your sweat licked collarbone in small kisses, akin to devotion that he's missed leaving against you after so long without you by his side.
"I⊠apologize." His voice is breathless when he hesitantly leans away from you, blushing deeply as he pulls out with a hiss and takes the condom off to toss it into the bin by the side of the bed. He almost looks embarrassed⊠"I should have prepared you more, that was⊠desperate of me."
"It was perfect, L⊠come here."
You don't need to ask again when he crawls back on top of you with a content hum, nuzzling into your throat when you curl your arms around him and let him go completely limp against you, exhausted as the stress of the case catches up with him violently.
"Stay."
"Of course I willâŠ"
"No, I mean here." The vulnerability in his tone doesn't go unnoticed when his hands slip under your spine, keeping you securely against him even if you had no intention of leaving him in the first place. "With me, on the case."
"Depends⊠still not gonna be able to focus, are you?"
"I'll manage, I find myself worrying more when you aren't by my side."
"You're so sweet, Ryu... I'll stay, now sleep. I'm not going anywhere."
