Work Text:
It’s not that he can’t sleep. L just won’t – which is pissing Light off. They spend hours in the bedroom with every lamp on. Eyes drooping, Light asks if L can put the laptop away. Same answer, every time.
“I have to work,” L says. “Kira doesn’t sleep, so neither will I.”
Any normal man might’ve committed murder by now, but Light isn’t normal. He’s a good person and he has patience. Soon, L will collapse from exhaustion. Light will then pick up his limp body, deposit him under the covers, and they’ll snooze for a shared 12 hours. Except L’s been awake for three days straight, which means Light’s been awake as well. Exhaustion appears unattainable at the detective’s current activity rate.
No matter. Light just needs to speed up the process.
“Ryuzaki,” he says. “Have you ever been fingered?”
The constant clacking of laptop keys stills, and L glances to his bed partner. Light lays with both arms behind his head – shirt off, well-formed chest glowing under lamp-light. Dark eyes catch on golden ones, and they’re burning into each other.
“No.” L closes his laptop. “Have you?”
“Once. But I wasn’t very into it.” Light flexes one hand. “I prefer to give rather than receive. What about you?”
“I haven’t,” L stops and cuts his gaze away from Light. “I haven’t had any experiences from which to draw such a conclusion.”
“Oh?” Up on his elbows now, Light leans into the detective’s space. Cherry lip-balm suffuses him with a sweet perfume – a cute detail Light never noticed before. “Well. I guess you haven’t heard about the thought-processing boost orgasms can give the brain.”
A thin, near invisible brow raises with L’s replying scoff. The lie isn’t meant to convince solely by its existence, though; Light knows L only believes what’s convenient for him. He’s just got to make this lie worth being fooled by.
“It’s the blood.” Light smooths his hand over L’s knee and relishes the other man’s shudder. “After orgasm, the whole body gets a rush that sparks new neural pathways opening.”
His fingers crawl over denim fabric loose enough to betray L’s trembling thigh underneath. Because his aim is self-submission rather than overpowering the other man, Light lets his touch linger far from the common sensual sites. He kneads his index and middle fingers into L’s soft spots – his thighs, his stomach, his wasp-like waist. The detective moves only in reaction: trembling without a word for or against Light’s assertions. It’s obvious he wants to be convinced.
“And the more orgasms you get, the more pathways emerge.” Looming, Light plies his fabrication with lips brushing L’s ear. “Think how fast you’d catch Kira if you only fed your brain by getting fucked.”
This sparks action, at last, from L – his arms darting out and wrapping around Light’s neck. He draws the other man in with a sloppy, unskilled kiss. Eager, his little yelps and yips every time Light licks, nibbles, or sucks on his lips make up for the sheer drool tonnage L produces. His legs spread with only a decisive tap on the knee from Light. Their sprawl leaves a perfect space for Light to inhabit.
“Just one time,” L mumbles into what has to be his third kiss ever. “Just one time, to test if this orgasm theory’s true.”
Light strips L of his shirt first, which reveals a pair of nipples as pink as peach candies. They stand upright – aroused and as virgin to the touch as their bearer. As he unbuttons L’s jeans, Light uses his other hand to pinch and rub both nipples. L croons in delight, arching his chest into the new sensation.
His jeans slide off and onto the floor, followed by loose white boxers. L is nude, his only accessory the pink flush adorning his cheeks, shoulders, and chest. Hard and curved, his cock is smaller than Light’s seen before – though his references are pornography and his own equipment, so the data is skewed. With blasted out black pupils burning a hole in his tented pajama pants, Light undresses himself.
L gasps at the sight of his cock – bobbing at full hardness, it casts an intimidating shadow. Light smirks, unable to stop himself from stroking his length while his partner looks on. Nerves widen L’s eyes and part his lips. When their cocks finally kiss against each other, Light’s larger shaft dwarfs L’s needy organ. The rub gives them both pause as this sticky genital embrace is the first caress they’ve had since the investigation’s start.
A lucky sachet of lube gets fumbled from Light’s nightstand, which L flushes at while handing over. Precautionary measure is the line he gives on its existence. Light doesn’t care right then if the lube came from heaven itself. All he wants is the locked-in stare L has on the clear substance oozed over Light’s long fingers. With one lubed finger, he breaks the seal on the world’s greatest detective’s virginity. L whimpers, and Light kisses him – tasting the cherry sweet flavor on that pathetic sound.
One finger stretches L, while two fingers press on his prostate, and three have him squirming against the sheets. Intelligence holds on in his gaze by a single thread. Light asks for a condom, which comes from the same drawer as the lube. He can hear the thread breaking as he slides the rubber over his cock and it snaps with the first push of his tip into L’s well-softened hole.
A cock bores a deeper path than three fingers, and L huffs with each exploratory thrust Light makes. His aroused glow fades, almost shuddering before a hard roll of the hips slams Light into his fleshy prostate again. Around him L’s walls contract and shudder but Light doesn’t stop his rhythm. Again and again he hits L where he’s weak until pleasure flushes the whole of the detective. A single stroke and L cums over his own chest. He’s loose, almost boneless, and doesn’t fight being turned on his stomach.
“How do you feel?” Light rubs a palm over the pert little ass L presents to him. “Good? Smarter? Tired?”
“One more time,” L slurs into his pillow. “Need more proof.”
Light obliges the scientific inquiry. He mounts L from behind, drilling into him until his hips leave red marks on L’s pale cheeks. Third go-around, Light gets rougher and discovers being fucked on his side produces fresh moans from L, as does his cock being stroked and his mouth being fingered. On their fourth round, Light sits back and lets L ride him – the eager bounce earning L his first internal orgasm. Light eventually loses the condom and paints his pleasure over L’s entire body. They are sticky; they are loud; and they are as close as they’ll ever be.
The fifth time Light takes back the lead with L parked in his lap. He grinds his cock into the now-familiar soft spot in the detective with slow, even thrusts. His body aches from their sexual exercise. But the little snore L lets out where he’s buried his face in Light’s shoulder justifies his straining muscles. At last: L is asleep. Satisfaction burns through Light from his chest to his face but only for a moment. One blink lasts longer than he realizes and Light drops into dreamland, still cock-deep in a slumbering L.
When he wakes, Light is alone. L’s end of the handcuff chain is locked to their headboard and the shower’s running the next room over. He can’t escape how good the other man’s weight against him felt, or how the dismissive greeting he gets from L, toweled dry with skin pink from a hot shower, wounds Light more than it ever has. But he doesn’t press the issue, only takes his turn under the hot water and washes away what he can from the night before.
Yet when evening falls, and they’re alone in the bedroom once more, L doesn’t touch his laptop. He pours himself into Light’s lap with fingers tangled in brown hair and face flushed.
“We’re still so far from catching Kira.” L trails a finger around the shell of Light’s ear. “I think I need that orgasm treatment again, Light-kun. Can you help me?”
Six orgasms later, L lies snoring on Light’s chest while Light considers if dropping out of school to fuck L full-time might be his true calling. Oh well. Something to consider after they catch Kira.
