Summary: Prompt was - Nabari no Ou, Raikou/Gau: innocence vs. experience - Raikou enjoys teaching Gau about the ways of the world, and at the same time admires his innocence, and this is no exception. I hate writing summaries, in other words.
A/N: Self-beta'd, so apologies in advance for any errors!

"Have you ever thought about it?" Raikou asks offhandedly.

They've been talking about firsts - kisses, touches, sex. Gau blinks at him, blushing immediately. It's obvious he knows what's being asked, but he fidgets with the fear that maybe he's reading too much into things with the way Raikou is looking at him right now. "You mean..."

"Two guys."

"Not...really," answers Gau, the blush deepening from a light pink to an intense, struggling red. It's weird to be talking about this with Raikou of all people, and he sort of wishes he could vanish or fast-forward to when this conversation is over, before he can say things that will make things uncomfortable.

"What does that mean, 'not really?'" presses Raikou, body leaning forward on the couch. He's interested in Gau's answer and wonders if maybe he should have asked this question a lot sooner instead of waiting for a random Thursday night when they both can't sleep and raid the freezer at three in the morning for strawberry ice cream; settling instead for vanilla when they realise Yukimi must have finished it.

"Well, I've heard about it..." mumbles Gau, placing his bowl on the coffee table in front of them. "But I haven't thought about it."

Raikou laughs gently. "I see."

Gau opens his mouth, hesitating. "Have you?" His eyes widen and he stammers. "N-N-Nevermind - I shouldn't have asked. I-I'm sorry."

"Sometimes," answers Raikou honestly, ignoring the apology.

"Really?"

Raikou leans forward, placing his empty bowl on the table before slipping back into the comfort of the warm couch, silently appreciating the flustered look in Gau's eyes when their knees brush against each other accidentally. His fingertips skim beneath the younger boy's chin, lifting his head until their eyes lock are level.

He's never done this himself - never been the blatant aggressor. It's Gau's innocence shining through dark eyes that dominates Raikou's attention, his own eyes fixed on how Gau's hands are gripping his knees tightly, the only clear sign on tension from him.

"Do you think that's weird?" he asks, urging Gau just a little closer with his words.

Gau shakes his head, the nervousness in his body making it too hard to respond - even in brief, one-word sentences.

"Have you ever kissed anyone?" asks Raikou.

"N-No..." Gau's hands grip his knees more tightly, knuckles pale white.

Raikou smiles, knowing it's probably not a nice thing to be enjoying the effect he's having but too curious at how far he can push this before Gau makes him stop; if at all. "Do you want to?"

"Want to...kiss?" Gau's mouth falls open in shock. He gives a small laugh, voice strained. "Oh...you mean eventually."

"I mean right now."

"With...with you?" Gau seems more perplexed than before, perspiration thin but spreading at his temple.

Raikou resists the urge to chuckle, instead running his thumb over Gau's lower lip: he feels chapstick and a light film of saliva from where Gau's nervously attempted to wet the dry lips. "Am I no good?"

"N-No, it's not that!" protested Gau. "It's...it's just..."

Raikou waits patiently, eyes moving from Gau's face to focus on his lips, which look wet and warm. He wonders if Gau's chapstick is the regular kind, or if it would make his lips taste like something sweet; or if they would be free of taste - free of everything but heat.

"I don't want to mess up," says Gau, looking sheepish but feeling terrified. Raikou's low laugh tenses him further and he hates it - hates that he can't seem to get comfortable around his senpai, not when he's talking about kissing and...other things like that.

He's still berating himself for his own inexperience when his chin is tilted just so, mouth about to open to ask "what?" Raikou's lips are on his suddenly: but it's soft, a slow, warm feeling.

Gau briefly thinks about movies and television shows, when people grab each other passionately and all but devour each other's mouths. This kiss has all the same intensity, but none of the extra movement; he knows Raikou, knows that the barely-there hum is Raikou's body preparing. He's noticed it before fights, too - a silent hum, that seems to surround Raikou's body just before his sharper attacks.

Except now, it's all focused on him and Gau almost forgets to breathe entirely. The hand on his cheek is warm and makes him sigh, which Raikou takes advantage of to slip just the tip of his tongue inside Gau's mouth - along the white teeth, the roof of his mouth, and then, finally, his tongue itself.

Gau curses himself silently when his body stirs, and quickly; hardening at the last flicker of Raikou's mouth before he pulls back, eyes opening to look at Gau. There's a serious but calm look in his eyes, as if he's observing a test subject to see if he can apply more stimuli or leave his findings as is. He's pretty sure Raikou isn't into science at all, but it's the same determination he sees in his science teacher's eyes; except this is fiercer somehow, and all directed at Gau.

"...Um," he says finally. He wants to laugh, to be able to let go of his knees which are finally starting to go numb under his hands. He wants to stand and excuse himself to bed or the bathroom so he can go jerk off and not embarrass himself further.

"You look flushed," says Raikou, sliding his hand from Gau's cheek to his forehead. His touch is comforting, but doing nothing to assuage the tight knot of want in his stomach that's only clenching harder around his libido as Raikou's fingertips run through Gau's hair.

"I should probably get to bed," says Gau, trying to remember what a smile feels like. His muscles all feel over-stimulated, his mouth especially.

A confused look crosses Raikou's face. He chuckles, but his eyes suggest a cautious seriousness. "Was I really that bad?"

"No!" The words leave his mouth in a volume loud enough to wake at least half of the occupants in the high-rise. He settles for shaking his head to get the point across.

"Then what's wrong?" asks Raikou. "Do you not like it after all?"

It's in that moment that Gau knows he's doomed. He can't lie to Raikou, nor does he want to, really. Swallowing heavily, he tries to look his senpai in the eye, but fails; instead letting his gaze fall to his hands, which are resting awkwardly in his lap, his knees thankful for the respite.

"I...like it a little too much," he admits in a mumble.

Raikou doesn't catch it at first and is about to ask for clarification or for him to speak up louder - though not as loudly as his emphatic No! And then it clicks; his eyes turn immediately downward, meeting Gau's hands. Knowing he should probably think things through more or at least ask before reaching, he chooses to act on impulse, taking one of Gau's hands away and holding it; nudging the other away from their somewhat protective stance over his groin.

Gau's hard is all Raikou processes before he finds himself in the same predicament.

"...Gau," he says, and his voice sounds strange to him but he ignores it, letting go of his kouhai's hands and finding one of the belt looks on Gau's trousers. "Bear with me for a second," he adds and tugs; and with minimal effort, Gau is in his lap, straddled inexpertly but solidly on either side of Raikou's legs.

"R-R-Raikou?" asks Gau uncertainly. Fingers are resting at his groin - Raikou's fingers, which seem to be waiting, his face fixed into a concentrated frown. Then one button is undone, the zip of the fly being lowered carefully.

"Do you know what a hand job is?" asks Raikou, looking at Gau as his palm rubs against the obvious erection opposite him.

"...Yeah," admits Gau, having immense difficulty responding. Thoughts whir through his mind, all incoherent and a little scared. Raikou's fingers move beneath the cotton boxers, the other hand tugging down the elastic. Gau's cock feels cold, but not for long; Raikou's hand is warm, growing warmer with every stroke. Gau leans forward, resting his hands against Raikou's shoulders for balance, eyes closed.

He'd touched himself before, but not like this - not at this pace and not while sitting on top of Raikou, breathing him in, feeling the warmth encasing him in successive movements. Embarrassed but apologetically aroused, Gau thrusts forward, craving more - barely hearing Raikou's soft utterance of his name, lightly feeling the kisses on his neck, or his shirt being pulled upward, one hand skimming the skin. He can barely think or feel anything but Raikou, the thought of Raikou making him gasp, making him come in a restrained whimper, white puddles of release sticking to his stomach.

His head rests against Raikou's as he tried to calm down, his former anxiety replaced with satiated fatigue. A smile, bright and full and sexy splays across his lips before he speaks.

"That was good, senpai," he says honestly. There are probably better, more worthy things he could have said; but it's all right, he knows, to stick to basics at a time like this.

"It looked good," murmurs Raikou.

Gau's cheeks heat quickly; had Raikou been watching him? Rather than ask, he opens his eyes, looking suddenly forlorn.

"What is it, Gau?"

He frowns. "It's not fair."

"What isn't?"

Opting not to answer, Gau removs his hands from Raikou's shoulders, fingers hesitating mid-air before converging on the belt buckle Raikou wore.

"...Gau..." Raikou smiles, grabbing one of his wrists. "You don't have to do that."

"And if I want to?" challenges Gau, intensity practically burning behind his retinas.

Raikou doesn't say anything, only nodding. He watches as Gau undoes his belt, then the zipper and button below; he can't look away when Gau's hands find his cock, freeing it from his boxers and stroking twice experimentally. Raikou inhales sharply; one hand moving to Gau's waist, then behind it, squeezing the small but noticeable curve of his ass.

Gau's heart stops for just a second before beating again. He brings his hand to his mouth, spitting discretely into his palm before placing it back on Raikou's length.

"Unnnngh," says Raikou, his grip tightening, hips pushing unrelentingly upward, into the spit-slicked hand. Gau keeps his pace, speeding up a little more every few strokes, enjoying the sounds coming from his senpai - especially the way he says his name when telling him to speed up, slow down, or to never stop.

He's just about to raise his hand to his mouth one more time but Raikou catches it, forcing it to move more quickly along the shaft, his own palm squeezing toward the tip; Gau watches, fascinated. Raikou's brow knots, eyes closed; neck tilting backward against the couch as he came, wet and thick over Gau's hand and fingers.

"Sorry," says Raikou.

Gau blinks. He'd just seen one of the sexiest things of his life: Raikou's face, and the way it looked like it was being overwhelmed, yet still wanting more. There was no need to apologise, as far as he was concerned.

"What for?" he asks.

Raikou glances down at Gau's hands briefly. "For making a mess."

"Hmm?" Realisation dawns and Gau's face reddens, rivaling the deep pink on his senpai's face. He gives a short laugh. "Oh that. Don't worry about it."

An idea pops into his head suddenly and he lifts his hand to his mouth, licking slowly along one finger, tasting Raikou's come; then along the back of his hand, licking there; keeping his eyes solidly on Raikou.

Maybe he's not as innocent as he looks, thinks Raikou, giving Gau's ass one more squeeze. Gau yelps in surprise, apologising in a whisper.

Maybe not, smiles Raikou.
