Summary: The way Senga seems to pretend that those dirty text messages never happened bothers Nikaido so much more than he ever thought it would.
Notes: Collaboration with unmeiboy!! We have been helping each other with fic for like... 6 years and this is the first time we've ever written something together haha. Only took us a total of nearly four months. It's a sequel to one of the Christmas gift fics, here.

Senga gasps when Nikaido bites at his earlobe, hot tongue flicking against the piercing he has, and he wants to squirm away from the hot breath at the same time as he wants to have Nikaido closer. He's glad he has Nikaido's T-shirt to hold on to, squeezes the soft fabric as Nikaido's mouth moves from his ear to his throat, warm lips pressing against his skin.

 

Since Senga has no frame of reference, he doesn't know how this is supposed to feel, but it feels urgent, Nikaido's mouth so heated on his skin, and it sends tingles of want over his skin.

 

When Nikaido's lips part over his pulse Senga's breath catches in his throat, but he doesn't move away; in fact, all he does is clutch the T-shirt tighter while his hips roll just the slightest without him remembering telling them to do so. He gasps then, because Nikaido's body responds to his tiny movement, thrusts his hips forward, pushes Senga firmer against the mattress for a second, and what he feels then is a fully hard erection. A part of him wants to touch it, feel Nikaido's sounds against his skin instead of into the air like he had heard them before, when Nikaido forced Senga's hand to his crotch.

 

But before he stops hesitating Nikaido ducks lower and he loses his grip on the T-shirt, blindly reaching out to hold onto his shoulders instead. Then, before he knows it his own shirt is pushed up and there's lips hot on his skin. Senga feels his abs tense at the initial touch but lets himself lean into it when Nikaido smooths a hand along his side, a hand that stops at the hem of his pants. He's so focused on that hand that he doesn't think of the small, warm presses of lips against his skin until those lips part above his navel and there's teeth on the skin just above it. It doesn't exactly hurt when he bites, but then he toys with the skin, pulls on it while his thumb traces a vein that disappears into his pants and Senga's can't help the little whine that comes with another roll of his hips. He accidentally rubs his crotch against Nikaido's collarbones, a realization that makes him blush and quieten, but then Nikaido is up in his face again, and his eyes are so dark.

“Can I take this off?” He mumbles like he's ashamed of asking, and Senga nods, only to have Nikaido's lips against his again. This time their tongues meet within seconds, and he swears he can feel Nikaido rub against one of his legs when Senga licks at his tongue, then sucks a little on it, experimentally.

 

For a moment he even suspects Nikaido forgot about any removal of clothes, because when he does leave Senga's lips he's back at his neck, nipping on it while that damn hand on his hip keeps stroking so softly that his skin jumps, so lightly that it tingles all the way to his crotch. But then he's back on track again, urges Senga's back off the mattress long enough that he can pull the T-shirt over his head. Then Nikaido stills for a second, just looks at Senga until he lowers his head, and Senga has to squeeze one of his still clothed shoulders when there's a hot, wet touch to his nipple.

 

He hasn't tried playing with his nipples before, it hasn't really occurred to him that it could feel good; he both regrets it and doesn't now, because Nikaido's tongue makes him feel so hot and he realizes he might have been missing out, but at the same time he's glad the first time he feels it is like this.

 

“Nika...” He breathes, so low it's barely audible, but Nikaido hears it, stops to look up at him.

“Okay?” It's sweet how he looks genuinely worried, like he expects Senga to back out any second, like he's afraid that he will. He seems to calm down when he catches Senga's nod, though, switches to the other nipple. This time he closes his lips around it, sucks lightly, and Senga feels himself twitching in his pants. Had he been alone, he would have had his hands down his pants already, if he'd still been wearing his pants at all.

 

Nikaido can't possibly feel the twitch, because he's not touching his crotch, at all. He does hear the little breath though, a quick gasp, and his hips buck against Senga's thigh before he gets himself under control, keeps tending to his nipples.

“Kenpi,” He mumbles, voice hot right up against his skin as he refuses to look at Senga while he speaks. “How far can I go?”

 

The low question nearly makes him sigh. He's obviously gotten this far without a single protest from Senga, and he did tell Nikaido he would let him do anything, as long as he does it carefully.

“Keep going?” He responds weakly, not sure what else to say, because Nikaido knows, Nikaido must still remember.

“But,” Nikaido pauses, hips rolling again and Senga wants to ask what he's thinking about, “If I keep going, I... I'll...”

 

There's a sudden touch to his belly again, right where his pants start covering his skin, and he realizes Nikaido is working on getting them open. Again, he doesn't protest, but he feels Nikaido hesitate once he pops the button.

“Kenpi, you don't get it, do you?” For a couple seconds Nikaido's eyes meet his; they're on the verge of desperate, but Senga doesn't get to see it clearly before Nikaido hides his face against his neck, nips on the sensitive skin before he speaks again. “I want to fuck you, you know that right?”

“... Yeah.” He knows. He has known since those drunk texts, and it's kept him awake at night in more ways than one.

Nikaido still won't look at him. “And you're okay with that?”

“I think so.”

 

Apparently that's enough consent for Nikaido to continue getting his pants open. Within seconds his zipper is open and hands are tugging at his jeans, and Senga finds himself in his underwear, Nikaido's hand tracing his growing erection through the fabric while he goes back to sucking softly on his skin. Only this time he's at the thin skin over his hip bone, shifts a little closer towards his crotch, just a few centimeters but enough for Senga.

 

He hasn't ever had anyone's lips on his skin, not like this, and he's not sure he's supposed to feel this good from just these small touches, but he assumes it could be the novelty of the first time. Maybe it should be weird that it's his first time, but it's his best friend touching him like this, and he doesn't want him to stop.

 

“Hey, Nika,” Senga whispers, then exhales as slowly as he can when Nikaido squeezes a little around his cock. “Take it off?” He pulls on the T-shirt he still has his hands on, at his shoulders, and the response is so quick that he barely has time to blink before Nikaido is topless above him. Hesitantly, he puts his hands on his skin, strokes along the side of his rib cage, but doesn't look up because he can feel Nikaido's eyes on him. He does flick his eyes upwards when there's a touch to his cheek, just a soft hand, and he finds Nikaido looking at him more fondly than anyone ever has. It's intense, though, to keep the eye-contact, and so he looks down at Nikaido's chest again, tries rubbing a nipple, and earns a much larger reaction than he had expected. This time he doesn't just move a little, no, he thrusts against Senga, the hand still by his cheek twitching.

 

I might put my fingers in your mouth

 

A sentence from one of the dirty mails flashes before him and before he even thinks it through properly, Senga turns his head towards the touch, slips his tongue out against the tip of Nikaido's index finger. It pulls a shaky moan from Nikaido's lips, and then the finger is shifting to Senga's lips and Senga lets him push it past them, stopping before the second joint enters his mouth. Nikaido thrusts again, pants a little rough against Senga's underwear, but it's not something that bothers him. No, instead, as if on instinct, he finds himself sucking on the digit in his mouth, follows it with his tongue when it pushes in and out, slowly.

“Fuck,” he hears from above, and first he doesn't get it, then a second finger joins the one in his mouth, strokes his tongue when he meets them. Nikaido is breathing faster suddenly, his hips jerking a little sharper, and it crosses Senga's mind that he could be imagining Senga's lips and tongue working on something that would certainly feel a lot better. The thought makes him feel a little embarrassed, but it's not all bad, a little hot in a filthy way, and the realization that he thinks so makes him blush more than the embarrassment. It looks like what Nikaido said is true, that he really, really wants him.

 

It's almost like it takes a lot of willpower for Nikaido to tear his fingers away, but he replaces them quickly with his mouth, kisses him breathless. If it had felt urgent before, Nikaido's lips on his feel nearly desperate now, but he calms considerably when they break apart, looks away from Senga as if he's searching for something. A hand reaches for something on the bedside table, then Nikaido mumbles something to himself; when Senga follows his movements with his eyes he sees him grabbing a tube of lotion.

 

The item ends up dropped on the bed when he opts for getting his own pants off, and for the first time in a while, Senga feels a little lost now that he isn't being touched or can't touch on his own, either. It only lasts for so long, though, and soon Nikaido has both hands on Senga's hips, stilling while searching for eye-contact, silently asking permission. When he gets no protests he hooks his fingers under the hem of Senga's underwear, then pulls them off to leave him completely naked.

 

Luckily Nikaido doesn't pause to look at him again, because Senga feels a little embarrassed just at being entirely undressed in front of him. Instead he starts moving around, places a hand on the inside of Senga's thigh, pushes his legs apart to get in between them. Suddenly Senga understands what the lotion is for; Nikaido opens the cap, squeezes some onto his fingers, rubs them together before he urges Senga's thighs even further apart, making him feel even more awkward.

 

He already knows what to expect, he's not completely lost, but even so, he jerks a little when Nikaido's slick fingers rub at him, can't help but stiffen when he eases one finger inside.

“Relax, baby,” Nikaido tells him, voice so much deeper than normally that it makes something twist and spark inside Senga. Or perhaps it's what he's saying, that he's calling him baby, and that it doesn't sound the slightest forced or unfamiliar, rolls off his tongue like he's used to calling Senga his own. Nikaido really must have been thinking about this a lot, for a long time.

 

Senga is so lost in his thoughts, trying to distract himself from the strange but not exactly unpleasant sensation of Nikaido's finger pushing in and out of him, that he doesn't notice that Nikaido leans down until there's a slick, hot touch on the head of his cock. He's definitely not relaxing now, he catches himself thinking, but then it's there again. Nikaido is licking his erection while he pushes a second finger in next to the first, and while the stretch is definitely there, it's dulled considerably when lips part and his cock slides past them just a couple centimeters.

 

It's not a proper blowjob, even Senga can tell that; Nikaido is so light with his touches, doesn't suck even when he takes him inside his mouth, only tends to him with his tongue, bobs his head in shallow movements. However it's still better than anything he has ever felt, it's wet and hot and closes around his shaft and Senga has to hold on to the sheets for some reason he's not even sure that he knows himself. Even the fingers inside him are starting to feel good, like everything is heightened by the heat surrounding his cock, makes him feel a lot less uncertain about this. Nikaido is taking it slow for a while, like he's focusing on what's in his mouth rather than what he's doing with his fingers, but then he pulls away, looks up at Senga at the same time as he pushes deeper inside him. Senga's eyes close without him remembering actively telling them to, then his back arches and he moans, a sound of pleasure louder than he thought he would ever let out.

“That feel good?” Nikaido asks against Senga's hipbone, his voice husky as he nuzzles the skin there lightly, exhales what could be a moan against it; perhaps because that touch is all he can get for himself right now.

 

From then, Nikaido doesn't put his mouth back on Senga, and maybe that's for the best. His fingers keep pushing deep, brushing against that spot that makes Senga want to tell him to keep doing that forever. Hell, he probably would tell him to, if he had the courage, or wasn't so busy trying to breathe regularly. He glances down at Nikaido just as he straightens up a bit, pulls his fingers out only to push them back in with a third one added, and it's so weird to see the shadow of his erection in his underwear, to know that he's that hard because of Senga. It twitches once and it borders on obscene, Senga can't help but think, how he has legs spread wide and fingers inside him that his best friend can't wait to replace with his dick. But when he meets Nikaido's eyes for a split second it doesn't feel the slightest weird, because while he does see desperation and lust, there's something else in them too, something deeper, like care, or genuine feelings for him.

 

“Doesn't hurt, right?” Nikaido asks but keeps the pace up with his fingers. Senga's reactions can't be anything but positive, yet he tries to tell him that no, it doesn't hurt at all; he fails, words transforming into a moan before they even leave his lips, and he ends up just shaking his head instead. “Good.” He's left empty suddenly, feels his muscles clench now that they're used to having something inside, but Senga's attention is pointed in a whole different direction. Nikaido is sliding his own underwear off, squeezes some more lotion onto his hand before he rubs his own erection with it. Suddenly he feels tense and nervous, even though Nikaido treats him well and he trusts him to do it good. But it's also very, very surreal as Nikaido settles between his parted legs, strokes himself with a guttural moan, then smooths a hand a along Senga's thigh up to his waist, holds onto it as he positions himself.

“Relax,” He says again, must feel how Senga tenses when the head of his cock pokes at him. “God, you're so pretty.”

 

It's an unexpected compliment, takes him by surprise, but the tension in his body lessens and Nikaido pushes inside. Senga has to hold his breath at first, there's an odd burn to it that he's never felt before, but it's not enough for him to need Nikaido to stop. The first real thrust forces that breath out of him as he gasps even though it's really slow, and then there's another one, then a third, and before he knows it Nikaido has built a pace that makes it seem a lot like he's holding back. Senga is glad he does though, since he's still not sure if it feels good or just weird. Until there's a hand on his cock, a hand that gives a couple swift strokes, and he's definitely leaning towards this whole thing feeling good, now.

 

There's force behind the thrusts, but they don't speed up, even though Nikaido's breathing steadily grows harder. The hand on his hip is holding him tight, keeps him from being pushed further up on the bed every time Nikaido pushes all the way in, so much deeper than he had with his fingers and it makes him want to grab harder onto Nikaido and never let go.

 

Nikaido's mouth is at his collarbones, breathing hard between the kisses he presses to his skin, and every time their hips rock together it's like sparks of heat fly all along Senga's skin, from everywhere they touch down to his crotch and it's so much more than he's used to, since all he knows is his own touch. He does know his body well enough, though, only not exactly like this, but the arousal is the same and he really, really wants to wrap a hand around his cock, even more so when Nikaido's teeth scrape lightly against his skin as he groans.

 

Part of Nikaido is afraid to look. Afraid that maybe it really is a dream, a very long one, and that he doesn't have Senga beneath him, holding on to Nikaido's shoulders as he slowly pushes himself in and out of his body. And that if he looks, sees Senga all up in pleasure, face flushed a light red and his chest covered with a sheen of sweat, he might lose control completely, like he's been fearing. So he doesn't open his eyes even when one of the hands move to the back of his neck, lightly puts pressure on it upwards, and his body seems to understand what Senga wants before it gets through to his mind; next their lips are on each other again in a kiss that's not the slightest sweet or gentle, but it's Senga who starts it. Nikaido isn't going to protest, moans right into his mouth when Senga's tongue strokes along his own, gives a couple harder thrusts because he can't keep himself under control properly even without looking, but then he feels the gasp and he can't help it.

 

What he finds when he opens his eyes is better than anything his mind could ever have painted up. Senga is all that he has been imagining and more, eyes hooded and shiny lips parted, and when he flicks his eyes downwards he's sees that he's still hard, leaking more at the tip if anything. He thinks he doesn't dare looking further down, but his legs threaten to start aching and he has to straighten up, change his position a little, and it comes into view, his own cock sliding inside Senga. The visual part of it is almost too much for him, because it is exactly what he has longed for, for years, what he has fantasized about while touching himself, and now he's there. Taking every first he can from Senga, and by the looks of it, Senga is feeling good being taken.

 

He knows very well that he won't hear him ask for it, it's his first time and he saw the nervousness in his eyes before, can tell that he's hesitating before he moves his hands anywhere, but Nikaido's mind tells him that he can save it for another time. As if it's certain that there will be another time. It seems logical to him, high on pleasure as he is, and instead of lingering on that thought he increases his speed a little, hears Senga's response in his breath, and that he's so sensitive is such a turn-on. How he doesn't seem to know where to place his hands is hot too, like he's overwhelmed by how good it feels but can't reach Nikaido to let him know so he's clutching onto the sheets instead. His eyelids close too, when Nikaido thrusts a little harder, and then suddenly he moans, brighter than both of them would have expected. It takes him a couple thrusts to get into the same angle again but when he finds it he stays there, and Senga's back is arching as he's letting out little weak moans each time Nikaido slides inside him all the way, hitting him spot on if judging by his reactions.

 

He plays with the thought for a while, to keep fucking him and not touch him, but then again he really wants to see his face when he comes, when he for the first time gets an orgasm he didn't cause himself, so he lets go of Senga's hip with one hand, moves it to his crotch. The first touch has Senga's eyes fly open, but then Nikaido wraps his hand around his cock and his head falls back instead, hips eagerly moving as well as they can towards the touch.

 

Nikaido's afraid he might come right then without any warning whatsoever, because if he ignores his own hand stroking fast up and down Senga's erection he can almost see Senga moving up and down on Nikaido's own cock on his own, and his mind is flooded with the fantasies he's had of Senga on top of him. Senga on top, riding, rolling his hips like he doesn't just want it, more like he needs it, and it brings him dangerously close because how many times hasn't he come to those mental images.

 

“Nika,” Senga says then, wakes Nikaido from his thoughts. He sounds really out of breath, he's more or less moaning Nikaido's name and it's better than any fantasy he has ever had. So in hope of hearing it again he moves his hand a little faster, tighter, gives a couple harder thrusts and now Senga is moaning for real, louder, insides squeezing around Nikaido and he better be coming any second now as Nikaido is positive he won't last much longer.

 

He can't hold himself back, can't stop himself when his hips snap into Senga, when he groans deep in his throat. The sudden stillness momentarily makes him worried that maybe he scared Senga, that he's going too hard, but a long, kind of quiet moan accompanied by a twitch in his hand reveals that that's not it at all. Nikaido forces himself to keep his eyes open even though he's so, so close, focuses on what Senga looks like when he comes; breath hitching as he continues letting out little sounds, eyebrows furrowed and lips just slightly parted, hair a little messy and he's nothing but perfect.

 

Nikaido makes quick business of moving his hand back to Senga's hip, doesn't care that he smears come over his skin, holds him firmly as he forgets everything about nice and gentle, fucks him as hard as his subconscious makes him until he can't take it no more, until Senga's tiny noises get to his head, pushes him right over the edge and he spills himself inside him, chest heaving as he sets his hands on the mattress, arms shaking a little as he holds himself up through his orgasm. It's not until he has come down entirely that he realizes that maybe he should have pulled out, but on the other hand Senga doesn't look like he minds. At least not yet. Because there's a soft stroke up Nikaido's arm, then down, and when Nikaido pries his eyes open he sees that Senga isn't just touching him absentmindedly. There's a small smile on his face, and he's looking right up at Nikaido's face with a warm gaze.

 

“Nika,” is all he says, so low it's barely audible, but there's nothing weird in his voice. Nikaido wants to hear it as affection, but he's not sure, tries to confirm it by leaning down and press his own lips to that smile. And Senga pushes back, Senga pushes back and it's too good to be true and maybe, maybe the heat inside Nikaido's chest is the premonition of an explosion because he feels like he's burning, with so much more than just lust and arousal.

 

Senga's the one to softly break the kiss, and he strokes Nikaido's hair out of his face gently, looking a little embarrassed. “That was... Uhm... Wow.” He glances up at Nikaido, a hint of shy in his eyes as his hands move to Nikaido's shoulders to keep him where he is.

“Yeah.” Nikaido agrees, releasing a breath he hadn't known he'd been holding at Senga's assessment, and he leans his forehead on Senga's moist shoulder, thinking that he should probably pull out, but he doesn't want to just yet. “That. Was the best sex I've ever had.”

“... Me too?” Senga tries, then giggles at himself, and Nikaido smiles too even though Senga can't see it. He decides he has to pull out, because Senga's thighs must be seriously hurting, and when he does and the mess follows, Senga makes a sound of surprise.

“Sorry about that.” Nikaido apologizes, gently running hands up and down Senga's thighs. “I'll wear a condom next time.”

He wants to bite his tongue off when he hears what he just said, because there's no damn guarantee Senga would want to do this again, ever.

But Senga just nods slowly, and then bites his swollen lip uncertainly. “Nika?”

Nikaido makes an acknowledging sound, his whole body tensing at what's to come.

“Next time... Would you... Talk?” Senga asks, a pink blush on his cheeks and Nikaido's jaw drops. “I want to hear what those dirty things sound like when you're saying them.”

 

Nikaido's forehead falls back onto Senga's shoulder and he can't completely stifle a moan, a little overwhelmed with what Senga's saying and that there will be a next time. “You're gonna turn out to be so filthy, aren't you?”

Senga makes a little uncomfortable sound, and Nikaido turns his head enough to look up at his face, and sees the blush on his cheeks. “I'm sticky, at least.” Senga mumbles instead, and Nikaido breathes a laugh.

 

“Wanna take a shower?” He asks, and bites his lip a little before forcing out the question that will have to do as will-you-go-out-with-me substitute. “With me?”

And even though this is the furthest from how Nikaido's ever imagined confessing his feelings, Senga's small, happy smile is all he ever wanted anyway. “Yeah.”
