summary — L has a suspicion you'll take just as sweet as his favorite treats
warning — nsfw!, kissing, moaning, L eating you out, orgasm, relationship is not specified, afab reader, all characters are of age!
the flickering glow of the computer screens fills the dimly lit hotel room as L hunches over his desk, surrounded by plates that were once full of sugary treats. the kira case has consumed his every waking hour, and sugar has become his lifeline—the fuel that keeps his mind sharp and body awake. he absentmindedly reaches for another bite of cake, barely registering the taste as he stares at the lines of data scrolling across the screen.
you sit on the couch across the room, watching him with quiet curiosity. over the last few weeks, you’ve grown accustomed to his strange habits—the way he perches in his chair, the constant snacking, the way his mind never seems to stop moving. but it’s more than just fascination. your relationship with l has shifted recently, becoming something more. the lingering touches, the stolen glances, and the unspoken tension between you two are undeniable.
L is brilliant, meticulous, and utterly unique. but beneath the layers of his genius, there’s something soft and vulnerable. you see it in the way his dark eyes linger on you when he thinks you aren’t paying attention, and in the way his fingers graze yours for just a moment longer than necessary.
tonight feels different, though. there’s an electricity in the air, a tension that buzzes between you both, as if something unspoken hangs in the balance. you shift slightly, catching L’s attention as his dark eyes flick over to you. he doesn’t say anything, but you can feel the intensity of his gaze, and it makes your heart race.
he sets down his fork and makes his way over to you. his eyes are dark, piercing as they settle on you, studying your face with an intensity that makes you feel bare.
"you’ve been staring quite a bit recently" he says, his voice as quiet and deliberate as ever.
you blush, unable to stop the way your pulse quickens at his observation. "i could say the same about you”. he tilts his head slightly, considering your words, before he moves to sit beside you on the couch. the proximity is enough to make your skin tingle.
his eyes flicker down to your lips for just a moment before meeting your gaze again. there’s a depth of thought behind those dark eyes. he leans in, his lips brushing softly against yours. the kiss is tentative at first, but it doesn’t take long for it to deepen.
your relationship with L is still in its early stages. nothing’s official, but the pull between you both is unmistakable. the moments you’ve shared—stolen glances, lingering touches, and quiet conversations late into the night—have built something powerful. and though this isn’t your first kiss, every time l touches you, it feels like the first, as if he’s carefully discovering you all over again.
L treats every kiss as if it's a puzzle to be solved, as if there's a secret to be unlocked. his movements are always deliberate, his touches soft but calculated. tonight is no different.
his hand moves to cup your cheek, fingers cool against your flushed skin, and you can taste the lingering sweetness of the cake he’d been eating just moments before. the kiss is slow, deliberate, and like everything L does—calculated.
when he finally pulls back, his eyes search yours, darker now, more intense. he analyzes every inch of you, reading the subtle changes in your expression. his gaze lingers, thoughtful, calculating in that way only l can be, like he's weighing something important in his mind.
"you taste sweet" he murmurs, almost as if he’s confirming something he had suspected. his thumb brushes over your lower lip as his eyes flicker with something new, something more primal than the focused, analytical detective you’re used to seeing.
you’re breathless, your heart racing as you lean into his touch, the tension between you crackling like static. "is that why you kissed me?" you tease lightly, trying to break the intensity of the moment.
a small smile tugs at the corners of his lips. "partially” he admits, his voice lower now, more intimate. his hand trails down from your cheek to your neck, his fingers ghosting over your skin with a featherlight touch that makes your breath hitch. "i have… a bit of a sweet tooth" he murmurs, leaning in closer again. "it’s a habit i can’t quite break”.
before you can respond, his lips are on yours again, this time more insistent, more demanding. the kiss deepens, and you feel yourself melting into him, your body responding to his touch as the world around you blurs. his hand slides down to your back, leaning into you until you’re pressed against the couch, the warmth of his body seeping into yours. he kisses you harder, his breath growing more ragged with each passing second. there’s a hunger in the way he moves, a need that mirrors your own.
in this moment, it’s clear that this is more than just curiosity or desire—it’s a craving, a need, one that has been building between you both for far longer than either of you had realized. and now, with nothing standing in the way, the only question is how far you’re both willing to go.
you part your lips, inviting him further, and he responds immediately, his tongue teasing yours in deliberate strokes. he kisses you like he’s savoring the moment, like every second is part of some grand equation in his mind.
when he finally pulls back, you’re both breathing heavier, and his eyes search yours. there’s a question there, unspoken, but clear.
"what is it?" you whisper, your heart racing.
his thumb gently traces your bottom lip, his expression thoughtful yet tinged with something darker, more intense. “i wonder...” he murmurs, almost to himself. "if you taste as sweet as you look”.
your breath catches at his words, and you feel a flush spread across your cheeks. you’ve seen the way L devours sweets—cakes, candies, anything sugary to fuel his endless work. it’s a craving, an addiction even, driven by more than just a sweet tooth. you noticed how he seemed to indulge in desserts with an almost obsessive enjoyment, a way to keep himself sharp, to stay focused.
but now, he’s looking at you with that same hunger.
you swallow hard, your pulse quickening at the intensity of his gaze. “what do you mean?” you ask softly, though you already know.
L’s lips curve into a faint smile, his hand sliding up your side until his fingers rest against your neck, just below your ear. he leans in again, his breath warm against your skin as he whispers, "you always look so sweet... i can’t help but wonder how you’d taste". his voice is low, dripping with a curiosity that sends a thrill through you.
before you can respond, his lips are on your neck, pressing softly at first, then with more intent. you gasp, tilting your head to give him more access as his kisses trail down, slow and deliberate. his tongue flicks out, tasting your skin, and you shiver, your hands instinctively clutching at his shirt.
he’s careful, taking his time as he travels across your skin, savoring each touch of his lips to you, as if memorizing the way you respond. he slowly pulls down your pants, leaving you in your underwear as he kisses you over the fabric. this is way further than you’ve gone before. his urgency is making you crave him more than you ever have.
your chest rises and falls with your quickened breaths, anticipation swirling inside you. “L...”
his fingers ghost over the waistband of your underwear. you can feel your heart pounding in your chest, the air between you thick with tension and unspoken need. his lips curving into that smile you’ve come to adore. slowly, deliberately, he presses a kiss to your inner thigh, making your muscles tense. his lips trail upward, moving with agonizing slowness, his touch featherlight against the sensitive skin.
your hips shift unconsciously, and L pauses, his eyes flicking up to meet yours, studying you, gauging your reactions. “you’re sensitive here” he observes softly.
you bite your lip, unable to form a proper sentence as his fingers hook around the fabric of your underwear, bringing it down your legs. the cool air against your skin makes you gasp, and you can feel his gaze linger on you, as if committing the moment to memory.
L’s lips return to your skin, brushing softly over your mound before trailing lower, his breath warm against you. slowly, he takes his tongue and traces up your slit. the sensation sends a shiver down your spine, and you gasp softly.
he takes his time, moving with precision, kissing and licking every inch of you. his actions are fast enough to stimulate you, yet slow enough to leave you wanting more. each kiss, each touch from him feels deliberate, as if he’s savoring every second of this new territory.
your body reacts to him, arching slightly as he explores, making it impossible for you to stay still. every soft lick, every brush of his lips against you drives you deeper into a haze of pleasure. you’re caught between the need for more and the desire to let him continue at his agonizingly perfect pace.
his actions feel like a slow burn, the tension building with each minute. L’s focus is unwavering, his dark eyes occasionally flicking up to watch your reactions, his own pleasure seemingly drawn from the way your body responds to his touch.
L hums in content, pulling back slightly as his eyes meet yours, filled with a hunger that both excites and unnerves you. “you’re even sweeter than i thought” he says. his words send a shiver down your spine. it’s as if he’s confirming a theory, your body the subject of his thorough investigation. there’s something so intoxicating about the way L studies you, as if you’re a puzzle he’s determined to solve, but one he’s taking his time with, savoring each piece as he uncovers it.
“L…” you whisper, your voice barely audible. he tilts his head slightly, his fingertips brushing against your skin.
“tell me if you want me to stop” he murmurs, his voice gentle but laced with unmistakable desire. he’s giving you the out, but the hunger in his eyes betrays how much he doesn’t want you to take it.
“don’t stop” you respond instantly, shaking your head, the words coming out faster than you intended. “please, don’t stop.”
he’s determined to find your most sensitive spot, and when he does, you can’t help the sudden jolt of your body. he hums against you, the vibration only heightening the sensation. his tongue moves purposefully, brushing over the same spot again and again, each stroke more deliberate than the last.
your breath comes in short gasps, your hips moving instinctively toward him, seeking more of the overwhelming pleasure he’s so expertly giving. the sounds that escape you are beyond your control—desperate, needy, urging him on. L doesn’t stop, his movements precise and relentless, drawing you closer and closer to the edge.
he watches you closely, eyes filled with curiosity and hunger. his lips and tongue move with a calculated precision, learning your body, testing your responses. he’s quiet, his attention solely on you, as if nothing else in the world matters except this moment. and when his lips finally wrap around your clit, the sensation is so overwhelming you can’t hold back the moan that escapes your lips.
the sound seems to encourage him, and his movements become more confident. he sucks at a rhythm that makes your toes curl. your grip tightens on his locks, body starting to tremble as the pleasure builds inside you.
you gasp his name, your voice breathless and shaky, and L responds with a soft hum, the vibration sending another wave of pleasure coursing through you. he’s relentless now, his lips and tongue working in perfect sync, drawing out every sound from you.
your body arches toward him, your breathing ragged as you near your breaking point. the intensity of his touch is overwhelming, almost too much to bear. you’re so close, teetering on the edge of release, and you can feel your muscles tightening, your entire body wound tight with anticipation.
L senses it too. his movements quicken just slightly, enough to push you over that edge. with a strangled cry, you shatter, pleasure coursing through you in waves as your body trembles beneath him. he doesn’t stop, holding your hips in place as his lips and tongue continue their work, drawing out every last bit of your orgasm until you’re left breathless and trembling.
when he finally pulls away, his lips glistening, his gaze meets yours once more. there’s a satisfied gleam in his eyes.his hand moves to cup your cheek, his thumb brushing over your flushed skin as he leans in to kiss you again—this time slow, tender, the taste of you still on his lips. you melt into the kiss, your body still buzzing with the aftermath of your release. L pulls you closer, wrapping his arms around you as you settle into his embrace, your heart still racing and your mind spinning.
