Work Text: 作品內文：
The way it starts is totally, entirely innocent. A joke. Kunimi's cousin is messing around with makeup while he and Kindaichi are playing video games, and she stares at the bright red lipstick in her hand and a grin curves over her face.
一切的開始都是完全無辜的。一個玩笑。當Kunimi和Kindaichi在玩電子遊戲時，Kunimi的表妹正在玩化妝，她看著手中的鮮紅唇膏，臉上浮現一絲笑意。
"Hey Akira," she taps his shoulder until he looks up, sleepy eyed as ever. "You should try this too, I bet you'll look hot."
「嘿，Akira，」她輕輕拍了拍他的肩膀，直到他睜開睡眼朦朧的眼睛。「你也應該試試這個，我敢打賭你會看起來很性感。」
She laughs, and Kunimi rolls his eyes but sits up on his elbows and puckers his mouth in invitation. And that's all it is. A curiosity, a joke.
她笑了起來，Kunimi翻了翻白眼，但還是坐起身來，撅起嘴唇示意。這只是個好奇，一個玩笑而已。
Kindaichi barely pays attention to the exchange until both of them are chuckling, and he looks up to see Kunimi smirking, lips painted red, slightly smeared at the edges from the awkwardness of applying lipstick to someone else's mouth...
Kindaichi 幾乎沒注意到他們的交流，直到他們都笑個不停，他抬頭看見Kunimi嘴角掛著一絲嘲弄的笑意，嘴唇被紅色唇膏塗滿，邊緣微微模糊，因為將口紅塗在別人嘴上有些尷尬…
He has to force a laugh because he can't actually tear his eyes away from it. When he manages it's only because he has to shuffle positions so the fact that he has a fucking boner over his best friend wearing lipstick isn't painfully obvious.
他不得不勉強笑了笑，因為他實際上無法移開目光。當他終於做到時，只是因為他不得不調整姿勢，這樣他對著他最好的朋友擦口紅時勃起的事實不會太明顯。
Kunimi, apparently deciding that Kindaichi isn't having a hard enough time already, is too lazy to go and clean it off his mouth. So it just... stays there, in the periphery of Kindaichi's vision, red as a siren. He catches every time Kunimi idly rubs his lips together, wonders about what the texture of his mouth is like... if it's softer than usual or if he tastes different.
Kunimi，顯然認為Kindaichi已經夠難受了，懶得去擦掉他嘴上的口紅。所以它就...留在那裡，在Kindaichi視野的邊緣，像一個紅色的警報。每次Kunimi隨意擦拭嘴唇時，他都會注意到，想著他的嘴巴的質地是什麼樣子...它是否比平常更柔軟，或者他的味道是否有所不同。
He's so lost is own lewd imagination about Kunimi and his mouth that when Kunimi's cousin stands up to leave, he jolts in surprise. Kunimi stares at him a little oddly, rolling off the bed with a hum after she goes. "I'm gonna wash this off."
他對Kunimi和他的嘴巴的淫蕩想像如此沉迷，以至於當Kunimi的表妹站起來離開時，他驚訝地猛地一跳。Kunimi有點奇怪地盯著他，她離開後，他輕輕地從床上滾下來，發出一聲嗯聲。“我要去洗掉這個。”
It's not that he means to whine at the idea, he just can't stop the sound before it comes out. Kunimi stops and raises an eyebrow at him, hovering in the middle of the room with a smirk slowly growing on his face.
他不是故意要抱怨這個想法，只是無法阻止聲音在他發出之前出來。Kunimi停下來，抬起眉毛看著他，在房間中間盤旋，臉上漸漸浮現出一絲得意的笑容。
"So you do like this," he pulls the small silver tube out of his pocket, shoving the door to his room closed with an elbow, and as much as Kindaichi wants to deny it, he's also been hard for the last hour thinking about it. He nods his head, giving in to whatever kind of mocking he'll get for it.
「所以你喜歡這樣嗎，」他從口袋裡拿出一支小銀管，用手肘把房門關上，盡管Kindaichi想否認，但他也已經想了一個小時，讓他硬得不行。他點點頭，屈服於無論他因此而受到怎樣的嘲笑。
"I- It um, looks really good," he grumbles, trying to make himself stop staring. Good is really an understatement. There's always been an extra prettiness to Kunimi, with his soft skin, and his delicate features, and it only stands out more with his mouth painted bright red like it is. Kunimi's grin widens just a little, and rather than leaving the room he settles himself in Kindaichi's lap.
「這、這個，看起來真的很好，」他嘟囔著，試圖讓自己停止凝視。好這個詞實在是過於含糊了。Kunimi總是有一種額外的美感，擁有柔軟的皮膚和精緻的容貌，而當他的嘴塗成鮮紅色時，這種美感更加突出。Kunimi的笑容微微擴大，他沒有離開房間，而是坐在Kindaichi的腿上。
“That's kinda weird, you know,” and he's laughing now, but not in the mocking way Kindaichi expected. It's bright, excited, and there's a flush settled high on the sharp curves of his cheeks, staining them a soft pink. Kindaichi snorts, leaning forward and fitting their lips together.
「這有點奇怪，你知道嗎，」他現在笑了，但不是Kindaichi預期的嘲笑方式。這笑容明亮、興奮，臉頰上高高凸起的曲線泛著淡淡的粉紅。Kindaichi哼了一聲，向前傾身，將嘴唇貼在一起。
Surprisingly, the lipstick doesn't taste like much of anything, but he drags his tongue against Kunimi's lower lip, pressing into his mouth when it opens. His hands go from being balled awkwardly between them to squeezing Kunimi's shirt at the small of his back, groaning. There's a hint of teeth to the kiss, and it's not until Kunimi pulls back slightly to alter the angle of his mouth that Kindaichi realizes the lipstick is smeared over his mouth more than before, and probably leaving red on his own skin.
令人驚訝的是，口紅的味道幾乎沒有什麼，但他用舌頭沿著Kunimi的下唇滑過，當嘴張開時，他深深地吻了進去。他的雙手從兩人之間尷尬地握成拳頭，轉而握住Kunimi背後的腰部，發出呻吟聲。這個吻帶有一絲牙齒的感覺，直到Kunimi稍微拉開身體，改變嘴巴的角度，Kindaichi才意識到口紅現在比以前更多地沾在他的嘴唇上，可能還在他的皮膚上留下紅色。
Kunimi hums, tilting his head and swiping his thumb at the corner of Kindaichi's mouth, pulling it away with lipstick on the pad of it. “Oops.”
Kunimi哼了一聲，歪著頭，用拇指掃過Kindaichi嘴角，帶著唇膏的痕跡，將它帶到拇指上。「糟糕。」
He doesn't look the least bit sorry, and Kindaichi finds that he isn't either. The red has migrated from Kunimi's lips to surrounding his mouth in a messy smear and somehow that's worse, even though Kindaichi knows he's the one flushed and panting already, it makes the hunger in Kunimi's dark eyes shine brighter, a mark that he just maybe has as much lust coiling hot and demanding in the pit of his stomach as Kindaichi does.
他看起來一點也不抱歉，而Kindaichi發現他也不後悔。紅色從Kunimi的嘴唇擴散到周圍的嘴巴，弄得一團糟，這種情況更糟，即使Kindaichi知道自己臉紅氣喘，使Kunimi那雙黑眼睛中的渴望更加閃亮，標誌著他可能和Kindaichi一樣，胃中也燃燒著同樣熾熱且迫切的慾望。
(He really shouldn't think about these things with Kunimi already in his lap—grinding shamelessly up against him and trying to swallow down every groan, every traitorous word that wants to slip out of his mouth.)
（他真的不應該在Kunimi已經坐在他腿上時想這些事情——無恥地摩擦著他，試圖吞下每一聲呻吟，每一個想要從他嘴裡滑出的背叛性詞語。）
Kunimi flutters kisses against the side of his neck, tongue poking out to drag over the thudding of Kindaichi's pulse, peppering him with more tiny red marks and little tugs of teeth. He pauses, the bridge of his nose nuzzling into the junction of Kindaichi's shoulder and his neck, face hidden there. “Hey.”
Kunimi在他的脖子側面飄來飄去親吻，舌頭伸出來在Kindaichi的脈搏上拖動，用更多小小的紅印和輕輕的咬牙來灑他。他停下來，鼻樑蠢蠢欲動地蜷入Kindaichi的肩膀和脖子的交界處，臉藏在那裡。“嘿。”
“What?” Kindaichi grunts, trying to fight the unsteadiness of his own voice, the way his blood is purring hot in his veins. Kunimi nips him again, making his breathing hitch.
「什麼？」Kindaichi 咕嚕著，試圖抵抗自己聲音的不穩定，以及他的血液在靜脈中熱烈咆哮。Kunimi 再次咬他，讓他的呼吸突然停頓。
“Can I suck you off?” He asks it in such a casual tone, like he's asking what kind of game Kindaichi wants to play or if he got notes for a class and Kindaichi chokes on his next breath. He nods his head when he finally drags air into his lungs again, and he's pretty sure Kunimi only asked to get a reaction out of him because it's not a question that frequently gets answered with a 'no'.
「我能給你口交嗎？」他用一種非常隨意的口吻問道，就像問Kindaichi想玩什麼遊戲，或者他有沒有上課的筆記一樣，Kindaichi幾乎窒息。當他終於再次吸進肺裡的空氣時，他點點頭，他很確定Kunimi只是為了引起他的反應才問這個問題，因為這不是一個經常會被回答為「不行」的問題。
And sure enough, Kunimi snickers softly to himself before crawling out of Kindaichi's lap and settling on his knees between Kindaichi's thighs instead. There's a grin, a raised eyebrow before Kunimi is uncapping the lipstick and passing it into Kindaichi's hand, tilting his head back slightly to make it easier, lips together.
果然，Kunimi在爬出Kindaichi的膝蓋後對自己輕輕地窃笑，然後在Kindaichi的大腿之間跪下。在將口紅打開並將其遞給Kindaichi之前，他露出一絲笑容，一隻眉毛扬起，稍微仰起頭讓事情變得更容易，嘴唇緊閉。
Kindaichi's mind pulls thin and blank for a moment before he realizes what Kunimi is expecting, and even though his hand shakes, he manages to do a passable job of painting Kunimi's mouth pretty and red all over again. There's enough making a mess of his face already that Kindaichi figures his own mistakes don't stand out too much and mesmerized he presses his thumb against Kunimi's lower lip.
Kindaichi的腦海一片空白，片刻後他意識到Kunimi在期待什麼，盡管手在顫抖，他還是成功地將Kunimi的嘴唇重新塗抹得美麗而紅。他的臉上已經亂糟糟的，Kindaichi覺得自己的錯誤應該不會太明顯，他入迷地將拇指按在Kunimi的下唇上。
Kunimi's mouth opens easily, letting the single digit slide inside, dragging his tongue over the red tinted tip before closing his lips around it and sucking…
Kunimi的嘴巴輕易地張開，讓那根手指滑進去，在紅色的尖端上拖動舌頭，然後將嘴唇合攏並吮吸著…
His head falls back against the edge of the bed behind him with a groan, the shooting jolt of pleasure from it a surprise. Kunimi's teeth tease at him slightly before letting it slide free, a thin thread of his saliva connecting the two for a moment before it breaks. Kunimi's lidded eyes are hazy, and when his hands go to the task of pulling Kindaichi's jeans open there's an unusual sense of urgency in his motions. Kindaichi lifts his hips off the floor, hoping that Kunimi doesn't notice the slick, stained state that he's left his boxers in.
他的頭向後仰靠在床邊，發出一聲呻吟，從中感受到的快感讓他驚訝。Kunimi的牙齒輕輕地戲弄著他，然後讓手指滑出，他們之間短暫地連接著一條薄薄的唾液線，然後斷裂。Kunimi的眼睛有些迷濛，當他的手開始拉開Kindaichi的牛仔褲時，他的動作中帶著一種不尋常的緊迫感。Kindaichi抬起臀部，希望Kunimi沒有注意到他已經把內褲弄得濕潤而髒亂。
Of course, he isn't that lucky, though, because Kunimi shoves his jeans halfway down his thighs but cups his hand around the front of Kindaichi's boxers, thumb pressing into the dark wet patch in the fabric left by his cock. He arches up into the slight contact, squeezing his eyes closed with a soft hiss escaping from between his teeth. Kunimi seems content for a moment to rub his thumb into the spot, to tease the rough fabric against Kindaichi's already overcharged nerves, and Kindaichi forces his eyes open to try and glare at Kunimi in an encouragement for him to move along.
當然，他沒那麼幸運，因為Kunimi將牛仔褲拉到大腿中間，但手卻環繞在Kindaichi的內褲前面，拇指壓在布料上由他的雞巴留下的黑暗濕漬上。他因輕微的接觸而挺身而起，緊閉雙眼，從牙齒間發出輕柔的嘶嘶聲。Kunimi似乎滿足於用拇指揉搓這個地方，用粗糙的布料逗弄Kindaichi已經過度敏感的神經，Kindaichi強迫自己睜開眼睛，試圖瞪著Kunimi鼓勵他繼續。
Kunimi's lips twitch upward into a slight smirk, shifting so he can lean all the way over and kiss softly over Kindaichi's cock through the fabric as well. Kindaichi can feel the warmth of his mouth, the soft damp exhale of his breath. It's close enough to be torture, still dulled and denied by the fabric, and Kindaichi digs his teeth into his lower lip and whimpers into it, clenching and releasing his fists in an effort to focus on anything else.
Kunimi的嘴角微微上揚，轉身靠近，輕輕地親吻Kindaichi的雞巴透過布料。Kindaichi能感受到他嘴巴的溫暖，柔軟的濕氣。這近在咫尺卻被布料阻擋的感覺仍然是折磨，Kindaichi咬住下唇，對著下唇發出呻吟，緊緊握住並放開拳頭，努力專注於其他事物。
It fails, of course, but Kunimi takes pity and shoves his boxers down as well, fingers wrapping around the base to hold it steady while he presses a kiss to the very tip, staining it red. His mouth opens, tongue pressing the weeping slit of Kindaichi's cock, flicking over it in tiny, delicate strokes that do nothing to stop Kindaichi's squirming. He's struggling to keep his hips from jerking upwards, letting Kunimi swallow him down at the pace he has picked out already.
當然失敗了，但Kunimi心生憐憫，也將自己的內褲拉下，手指環繞住基部固定住，同時親吻龜頭，染上一抹紅暈。他睜開嘴，舌頭輕輕舔過Kindaichi陰莖上的淚孔，輕柔地划過，無法阻止Kindaichi的掙扎。他努力不讓自己的臀部猛地抬起，讓Kunimi按照他已經選定的節奏將他吞噬。
Kunimi's fingers squeeze slightly tighter around the base of his cock, the other hand moving to balance his weight better. He reaches the ring of his fingers only to draw back slowly, hollowing his cheeks to drag suction as he goes. The head of Kindaichi's cock leaves his mouth with a pop, and Kunimi tilts his head to the side to suck wet kisses along the shaft, his eyes darting up when Kindaichi can't keep himself from groaning any longer.
Kunimi的手指稍微緊緊捏住陰莖的基部，另一隻手調整重心。他的手指只觸及到環的邊緣，然後慢慢後退，臉頰凹陷，帶著吸力向後拖動。Kindaichi的陰莖頭帶著一聲啪地離開他的嘴巴，Kunimi側頭沿著陰莖吸吮濕潤的親吻，當Kindaichi再也忍不住呻吟時，他抬起頭，眼神飄忽。
Without thinking, he lifts one hand to stroke Kunimi's hair back from his face, shivering and carding his fingers through the soft locks again and again. Kunimi makes a small sound, leaning into the contact before wrapping his lips around Kindaichi's cock once more, this time taking a deep breath and sinking all the way down, holding Kindaichi's hips with both of his hands.
不假思索，他抬起一隻手，撫摸Kunimi的頭髮，顫抖著一遍又一遍地用手指穿過柔軟的髮絲。Kunimi發出一聲輕微的聲音，靠近這個接觸，然後再次將嘴唇包裹在Kindaichi的陰莖周圍，這一次深深吸氣，一口氣沉入，用雙手抓住Kindaichi的臀部。
Despite his best efforts not to, Kindaichi jerks in surprise at the sudden tightness of Kunimi's throat around him, the hand not holding tight to the back of Kunimi's head balling into a fist and pounding against the floor. Kunimi pins his hips harder at the jolt, breathing unevenly through his nose as his throat constricts, muscles twitching and convulsing as he swallows around Kindaichi, eyes closing. It's not a feeling that Kindaichi is used to, and he has to use all his self-control to keep himself from thrusting up in a desperate attempt to bury himself further into the wet heat of Kunimi's mouth.
盡管他盡力不這樣做，Kindaichi對Kunimi的喉嚨突然收緊感到驚訝，沒有緊握住Kunimi頭部的手握成拳頭，猛烈地砰地一聲敲打在地板上。Kunimi在這一震動下更用力地固定他的臀部，鼻子不均勻地呼吸，喉嚨收緊，肌肉抽搐，痙攣，當他吞嚥時，眼睛閉上。這不是Kindaichi習慣的感覺，他必須全力控制自己，不讓自己向上猛推，試圖將自己更深地埋入Kunimi濕熱的口中。
His fingers tighten in Kunimi's hair, making a little whining sound hiss out of his nose. Kindaichi bites down on his lip again, giving it an experimental tug. Kunimi follows the guidance of his hand easily, moving just enough that he must still feel the slight tug, but he doesn't seem to have any complaint about Kindaichi guiding his head up and down, pressing his tongue against the underside of his cock, lapping at the head when he gets the chance to.
他的手指緊緊抓住Kunimi的頭髮，讓他的鼻子發出一聲小小的嗚咽聲。Kindaichi再次咬住嘴唇，輕輕地拉了一下。Kunimi很容易地跟隨他的手的引導，移動得剛好能感受到輕微的拉扯，但他似乎對Kindaichi引導他上下移動頭部，舌頭壓在陰莖的底部，有機會時舔舐龜頭，沒有任何怨言。
Red is smeared all along the slick surface of his skin, and Kindaichi is panting unevenly as he stares at Kunimi. There's sound attached to each breath, short groans that only multiply with his desperation. Kunimi opens his eyes to lock their gazes, moving against Kindaichi's guidance to hold just the head in his mouth instead, lapping at it. His hand wraps around the rest of Kindaichi's cock, stroking the cooling skin. It makes Kindaichi realize what a mess they both are, and with his back arching he gives Kunimi's hair another tug, a warning this time. “W- wait—Akira, I'm—“
紅色沿著他的皮膚滑膩的表面擦拭，Kindaichi不規則地喘著氣盯著Kunimi。每一口氣都伴隨著聲音，短促的呻吟隨著他的絕望而倍增。Kunimi睜開眼睛，鎖定他們的目光，違背Kindaichi的引導，只將龜頭放入口中，舔舐著。他的手環繞住Kindaichi的陰莖其餘部分，撫摸著冷卻的皮膚。這讓Kindaichi意識到他們兩個有多麼混亂，當他的背拱起時，他再次拉了一下Kunimi的頭髮，這次是警告。“等等—Akira，我—“
He doesn't even have time to try and correct himself on the use of Kunimi's given name, too distracted by the parting of his red lips. He hovers his mouth just over the head of Kindaichi's cock, stroking it harder now, tongue poking slightly out of the open space. The view alone would be enough to topple Kindaichi over the edge, and he forces himself to keep his eyes open to watch the first spurt of come land on Kunimi's tongue and paint a white line across it.
他甚至沒有時間試圖更正對Kunimi的名字的使用，他被他紅唇的分開分散了注意力。他的嘴唇懸停在Kindaichi的陰莖頭上，現在更用力地撫摸著，舌頭微微伸出。單是這個景象就足以讓Kindaichi心猿意馬，他強迫自己睜開眼睛看著第一滴精液落在Kunimi的舌頭上，畫出一條白線。
Kunimi doesn't stop stroking, doesn't close his mouth, but still ends up covering more of his face than just his tongue. Kindaichi groans, throwing his head back when his orgasm finally finishes, feeling like he's been sucked out of his own body. He's not prepared to look at Kunimi with come covering his face and lipstick smeared on his mouth—the delightful, sinful mess that he's been made into.
Kunimi不停地撫摸，不合上嘴，但最終卻覆蓋了他臉上更多的部位，不僅僅是他的舌頭。當Kindaichi的高潮終於結束時，他發出呻吟聲，感覺自己被吸出了身體。他沒有準備好看著Kunimi臉上滿是精液，嘴唇上沾滿口紅的樣子—他被變成了一個令人愉悅、罪惡的混亂。
He reaches forward instead, fingers wrapping around Kunimi's thigh and sliding upward to push a hand into the limited space of his jeans. His cock, when Kindaichi's hand wraps around it, is just as hard and slick as Kindaichi's was, and ignorant of the come still staining Kunimi's face, Kindaichi leans in to kiss him while stroking his cock. He can taste the bitterness of his own release on Kunimi's tongue, but rather than being bothered by it, it only encourages him to lick deeper, to rub their tongues together with greater hunger and suck Kunimi's bottom lip into his mouth.
他伸手向前，手指纏繞著Kunimi的大腿，向上滑動，伸進他牛仔褲有限的空間裡。當Kindaichi的手包裹住他的雞巴時，他的雞巴和Kindaichi的一樣硬又滑溜，完全不在乎仍然沾滿Kunimi臉上的精液，Kindaichi靠近親吻他，同時撫摸他的雞巴。他可以嘗到自己射精的苦澀味道在Kunimi的舌頭上，但他並不為此困擾，反而更加鼓勵他深深地舔舐，更加飢渴地摩擦他們的舌頭，將Kunimi的下唇吸進他的嘴裡。
It doesn't take long for Kunimi to start releasing breathy little moans against his mouth, fucking his hips forward into the circle of Kindaichi's fist. He groans, short and clipped, hiding his face against Kunimi's shoulder. He wants to tell Kunimi that he makes a beautiful wreck, but unable to find the words he just holds on tighter as Kunimi comes as well, nails digging into his shoulders in an attempt to ground himself, slumping on Kindaichi's chest and panting when he finishes.
Kunimi很快就開始在他的嘴唇上發出喘息的小聲，將臀部向前推進Kindaichi的拳頭中。他呻吟著，短促而明顯，將臉藏在Kunimi的肩膀上。他想告訴Kunimi他變成了一個美麗的混亂，但無法找到詞語，當Kunimi也達到高潮時，他只是更緊地抱住對方，指甲深深地掐進他的肩膀，試圖讓自己穩定下來，在Kindaichi的胸膛上倒下，喘息著結束時。
Kindaichi slides his hand out to prevent tormenting Kunimi into over stimulation, planting a kiss on his temple instead and mumbling into the skin. “Please keep that lipstick.”
Kindaichi 伸出手阻止折磨 Kunimi 过度刺激，转而在他的太阳穴上吻了一下，轻声说道。“请留下那唇膏。”
Kunimi laughs and nods his head, eyes shut, humming softly as Kindaichi scratches his back.
Kunimi 笑了笑，闭上眼睛点了点头，轻哼着，而 Kindaichi 抓着他的背轻轻挠着。
Kindaichi, days later, is still trying to get lipstick stains off of his crotch.
几天后，Kindaichi 仍在努力清除裤裆上的唇膏污渍。
