Nikaido looks at the crowd before him, with a cigarette in one hand and a White Russian with less cream and more vodka in the other. Today he hasn't bothered dressing up, feeling a bit wrung out from everything lately, and he's just not in the mood for being too classy. He's wearing a simple black button down paired with a thin silver necklace and tight black jeans, and he's leaning against a pillar, just looking.

He's not a dancer, not like this, can't even imagine sinking low enough to head into the writhing crowd just to find a stranger to fuck. He makes a face at the mere thought of it and inhales some smoke to calm down. The atmosphere is already dim with smoke and flashing lights, heavy music beating through his entire body, and normally he loves this, the feeling of club, but now he can't seem to relax.

In fact, nothing relaxes him these days. Rina does her best when she sees how tense he is, of course, but it's just not what he needs. He doesn't know what he needs, if he did he'd get it, but he's just constantly irritated, smoking twice as much as he normally does and not even a blowjob settles his nerves.

He breathes a frustrated sigh, trying not to think of it and sips his drink, thinking that he should have asked for even more vodka. He doesn't normally have drinks at all, prefers stronger stuff, but somehow he felt like trying something different tonight.

He sighs again, setting his drink down on a table, not really interested in finishing it. Instead he puts the cigarette to his lips, the taste of tobacco mixing in with coffee liquor and it's not that pleasant.

Something catches his eye in the crowd, but at first he doesn't know what it is, tries to search it out again but failing. Then he sees him, behind two girls in mini-skirts, wearing a black sparkly vest, hands clad in fingerless black gloves stroking away some sweaty strands of hair from his face as he dances with closed eyes.

Something sparks within Nikaido, something so intense that he frowns at himself, because it was only a one night stand like every other night. Yet he can't take his eyes off the boy, watches him between the gaps of people as he rolls his hips to the beat in a way that sends a tingle over Nikaido's skin, ignites the desire to have him do that in his lap.

Nikaido finishes the cigarette and thinks about lighting another, fingers itching to do something. But then the boy opens his eyes, slowly, meeting Nikaido's gaze dead on, a small smirk spreading on his lips.

Nikaido keeps his facial expression careless, but stares back at him challengingly, crossing his arms.

He remembers his name, Senga Kento, even though he's pretended he'd forgotten, remembers the voice that said it and the dark hesitant eyes. Now, they are anything but hesitant.

Senga's smirk only grows when he sees Nikaido's encouraging look, and his eyes fall half closed as he starts to move in earnest, putting on a show. Nikaido wants to wet his lips, smoke another cigarette, shift, but he doesn't, only stays where he is, keeping his position of power. But oh god it's hot. Senga looks up at him every other second, glancing through his bangs to make sure Nikaido's still looking even though people move in the way, and moves his hips like he's fucking begging to ride.

Nikaido narrows his eyes a little, can't help it, and waits for Senga to look at him again. When he does, he just cocks an eyebrow a little and then turns to leave.

He smirks as he heads for the stairs to the private booths, wondering how long it will take Senga to follow.

Rina's perched on the couch when he ascends the stairs, and he gently touches her shoulder before rounding the couch to sit down.

“Takashiii.” She whines when she feels his touch, and Nikaido raises an eyebrow at her. She's always perfectly composed, never sounds like that. At least not at work. “Don't go wandering off.”

“I wasn't.” He says simply, reaching out for a glass and the bottle of whiskey on the low table.

“You were.” Rina insists slowly, a mildly accusing edge to her tone, and she lies down to place her head in his lap. Nikaido looks down at her face, noticing her pink cheeks and the slight smudge of her lipgloss, and suddenly everything makes sense.

He pours himself the glass of whiskey and he can feel her breath through his shirt as he leans over her, before sitting back to drink some, waiting for her to go on.

“I hate men.” She breathes, contradicting herself by nuzzling at his crotch where he's already interested, and Nikaido can't help but smirk. “They never know how to make it good, only think about themselves.”

“Thought you'd learned to pick them with care.” Nikaido says calmly, letting her do as she pleases as usual.

“Mostly. Girls are so much better.” She mumbles into his jeans, the heat of her breath making his cock twitch. “They never leave you hanging.”

“That depends on your perspective.” Nikaido mutters sourly, and she breathes a laugh that makes him shiver.

“Get me off Takashi? Please?” She asks softly, mouthing at his growing erection through his pants and he frowns, for a second thinking about Senga showing up, but that only makes heat spark in his belly, and he gives in.

“Fine.” He says, sounding careless, but Rina looks at him with a knowing smile as she sits up, lipgloss even more smudged, and Nikaido figures the rest of it is on his jeans.

He sets his glass down and reaches out a hand for her, but she grabs his wrist with a small smile that makes him frown in confusion. Until she tugs him closer and then gently pushes at him to get off the couch. He stays where he is though, raising a questioning eyebrow at her.

“Please?” She begs, and she really does look desperate, eyes glittering with want.

Nikaido sighs, but obeys her wishes and gets to his knees between her legs, never one to deny her what she wants.

He doesn't go down on people, neither of them do, it's way too submissive of an act. Nikaido likes his control, but if anyone can take it from him, it's his sister.

She sighs when he kisses the inside of her thigh just above where her stay-ups end and bare skin starts, and she spreads her legs wider, making the short red dress she wears ride up.

Nikaido takes his time, kissing and licking his way up her thigh, slowly enough that she gets a hand in his hair and forces him closer. Nikaido breathes a short laugh at the way he's suddenly got her lace panties brushing his nose, but obeys and nuzzles her gently, smiling at how wet she is through the fabric.

She gasps and bucks her hips, but Nikaido pulls back a little, enough so that he can pull her underwear off of one leg, and she's surprisingly helpful when she realizes what he's doing. As soon as he's got them off she tugs at his hair again, urging him closer and lays a leg over his shoulder.

Nikaido smirks at her impatience, but understands as soon as he gets close enough to flick his tongue out and lick at her. He tastes something besides her, tastes latex and another man, and that makes him grab her thighs and pull her closer, pushing his tongue inside her without any teasing. Rina's moans are loud and sweet when he licks at her insides, her other hand joining the first in his hair and gripping hard.

“Takashi...” She gasps, and he can tell how close she already is from the way her thighs are trembling, and moves up to her clit instead, simultaneously pushing two fingers inside her to clench around.

The sound she makes is a high pitched whimper as he gently licks at her most sensitive spot and moves his fingers roughly in and out, and her hands seem intent to pull his hair out, but he likes it, knowing she's right on the edge. Then suddenly she jumps, lets out a gasp, and Nikaido almost pulls back to see what's going on because she sounds surprised, but right then she comes with a long moan, shivering and writhing against him. He lets her ride out her orgasm, his own erection throbbing at the way she clamps down around his fingers, the way she tastes, and eventually her hands in his hair shoves his head back, too sensitive to take any more.

“Your boyfriend's here.” She says, voice breathy as she releases his hair, fixes it, and Nikaido can hear the smug smile in her voice.

He tenses, knowing that what he just did is far from okay in the normal world, but forces himself to relax. He wipes his mouth on his sleeve as he stands, meeting Senga's wide eyes with an eyebrow raised in challenge.

Senga is beautiful where he stands, staring in disbelief at them, eyes flicking between Nikaido and his sister and he bites his lip.

Rina stands beside Nikaido, short even in her high heels, and he figures she must have fixed herself up, and she presses a soft kiss to his cheek.

“Thank you.” She smiles and then heads off towards the bathrooms.

Senga stares after her, and then back at Nikaido, who can't help but smirk at his shock.

“I thought...” Senga starts, and Nikaido relishes in the sound of his voice. “She... I thought she was your sister?!”

“Oh?” Nikaido asks, interested in how Senga might know that, and slowly steps closer. “And why is that?”

“She... Invited me tonight. As she did last time.” Senga says carefully, taking a step back when Nikaido starts to get too close, glances across the railing towards the people down on the dancefloor. “She told me... her brother missed me. I... figured that would be you.”

Nikaido can't hold back the laugh he breathes when he sees Senga blush at his supposed misassumption, and he's not sure whether he should be thankful or angry that Rina always seems to know what he needs.

“Clever, are we?” Nikaido asks, smirk still on his lips as he continues to step closer until Senga's backed against a wall, seeing his slight panic at being cornered when he feels the wall against his back. “She is my sister. Are you scared of me now?”

Senga stares, wide eyes as he tries to comprehend, and he looks a little disgusted. “I... How... With her... That's sick.”

His words are a little shaky, and he does seem a bit shaken as a whole.

Nikaido takes the final step into Senga's personal space, leaning forward to breathe in the cologne at his neck, and he can't stop the small sound of relief he makes when the scent sends tingles of anticipation over his skin. “It's not. She's my sister, and I take care of her. That's all.”

Nikaido says, his voice soft but with a threat behind it, daring Senga to question him again.

“That's... Uhm...” Senga starts hesitantly, but then stops himself on a shaky intake of breath as Nikaido gently brushes lips against his ear, placing his hands on the wall on either side of Senga's shoulders.

Nikaido finds an earring and tugs a little at it with his teeth, letting his breath ghost over Senga's skin, smiling when Senga gasps and a hand comes up to rest on Nikaido's shoulder.

“I...” Senga tries again, seeming determined to say something, but this time Nikaido's lips drop to Senga's neck, brushing over skin before he flicks his tongue out. Senga lets out a small sound, bucking his hips involuntarily.

“You?” Nikaido encourages with a smirk that Senga has to feel against his skin, but this is just so easy and Senga is so hot.

“I don't think...” Senga starts again, and Nikaido almost wants to hear what he has to say. But there's really only one thing he wants right now and that's Senga bouncing in his lap.

He shifts enough to press his thigh between Senga's and laughs a little at how hard he is, how his arousal doesn't seem to have decreased very much from watching Nikaido on his knees before his sister.

Senga's head tilts to the side where Nikaido is, his moan breathed right into Nikaido's ear, stirring his hair a little and it's so fucking hot Nikaido has to clench his hands not to react vocally himself.

Nikaido's not a pleaser, not in mentality. Of course he prefers his partners to enjoy it, but it's his own pleasure that matters most. But the way Senga moans, soft and desperate little sounds, has Nikaido's blood burn with the desire to please him, make him moan louder and loose his mind under Nikaido's hands.

“So, you still wanna ride my cock?” Nikaido asks, voice too deep to be casual, and Senga seems to give up his attempts at talking and just nods fervently, eyes darkening as Nikaido pulls back to look at his face.

“Figured that's what you wanted.” Nikaido says, voice dropping even lower and Senga shudders.

He pulls back enough to stand up properly, and then turns around and starts walking, hearing Senga scramble up to follow.

It's a split second decision he makes when he leads Senga down the stairs instead of into one of the rooms, and he glances back at Senga to see him look a little confused. He seems even more confused, if not scared, when Nikaido guides him through a door with a code-lock, then down another old staircase that leads to the basement floor. There are still old theatre props down here, large things like painted backdrops and an aged chandelier, and Nikaido can't help but smirk at Senga's bewildered and worried expression, clearly wondering where he's being taken.

There's another coded door, this one not as fancy and decorated as the one upstairs, and as Nikaido holds it open for Senga, Senga licks his lips nervously before stepping inside, seeming to consider if Nikaido's actually a murderer or something.

Behind the door is a corridor, not very long, but lit dimly, and Senga lets Nikaido pass him again to lead the way. It's a bit of a test, this, Nikaido has to admit, to see if Senga dares following him without knowing where he is.

At the end of the corridor are stairs that lead up to a final door, and as Nikaido pulls out keys to unlock it, he has to say Senga's managing this test a lot better than most other people he's brought before, not even asking where they're going.

When he pushes the door open and steps inside, he sees Senga's eyes widen in surprise as he hurries to walk inside too. It's a dining room, furnished expensively in cool colours, and there are flowers in vases and impeccably clean, enough that it's obvious there is a housekeeper.

Senga looks around in awe as Nikaido pulls the door shut and tosses his keys on the low table next to it, before grabbing Senga's wrist and tugs him along.

“Is this...” Senga asks, voice low in the quiet calm of the apartment. “Is this your apartment?”

“Yeah.” Nikaido agrees shortly as he drags Senga along through the living room to his bedroom, trying not to let him look around too much.

He shoves Senga inside before closing the door behind them slowly, capturing Senga's attention where he stands in the middle of the room looking a little uncertain. He stands out against the classy furnishing, like a rebel with his dark eyeliner and sparkly black vest, and Nikaido can't help licking his lips like a predator watching tonight's prey.

Senga's eyes are entirely focused on him, and they darken a little when they catch the movement.

“... It's really fancy here.” Senga says slowly, but his tone is seductive and his eyes sparkle, clearly just making conversation because he's not pressed against a mattress yet.

“Thanks.” Nikaido says, his answers short as they always are, but he wants to smile at how this time around, it's Senga who wants him. He did come back here just to sleep with Nikaido and it's an arousing thought.

He lets a small smirk onto his lips as he finally steps forward, the smirk widening as he sees Senga's little shiver of anticipation when he approaches.

Nikaido doesn't waste his time once he reaches Senga, twisting fingers tight in his brown sweaty hair and tugs him close, enough to press his lips against Senga's throat again. There's a small part of Nikaido that wants to kiss him, taste his mouth and devour him. But he doesn't kiss.

Senga moans right into his ear as he bites down gently on his skin, hands grabbing onto Nikaido's arms to keep himself steady, and it just turns Nikaido on even more.

He tilts Senga's head further back by his hair, enjoying the way he looses his balance a little and clutches tighter at Nikaido's arms.

Nikaido mouths at his Adam's apple while walking him backwards until Senga's legs hit the bed, and shoves him back onto it. Senga's eyes widen a little when he falls, but he lands softly, arms spread out to catch himself, and he remains like that, looking up at Nikaido with hooded eyes and pink cheeks.

A spike of arousal runs through Nikaido as he looks down at Senga waiting for him to do something, and can't help but wonder if he's this submissive because he likes it or because he's figured out that Nikaido probably likes it.

He follows Senga onto the bed, hovering over him, and Senga's hands immediately grab the collar of his shirt to tug him down. Nikaido realizes what he's doing and struggles, pressing a hand against Senga's shoulder to keep him down, and ends up with his face a decimetre from Senga's.

“No?” Senga breathes against his lips, sounding more amused than disappointed, but he doesn't loosen his grip.

“No.” Nikaido agrees, making a move to pull back, but Senga's strong.

“Not even a little?” Senga asks, in a tone that's almost begging. “I've been dreaming about it for weeks.”

He leans up as he speaks, and at the last few words his lips brush Nikaido's, just for a moment before Nikaido shoves him back down with a hand to his other shoulder as well, but the touch has already left his lips tingling.

“Maybe you can deserve it.” He says, voice deep with both anger and arousal, because he's never been forced into a kiss before, and at the same time he's never wanted to kiss anyone this much.

Senga's eyes darken in lust and determination as he lets go of Nikaido's collar, running hands down his back instead like he can't stop touching him, but he doesn't answer.

Nikaido grabs his hands in annoyance, thinking that Senga was easier to handle last time, but then pins his wrists to the bed on each side of his head, and Senga gasps, looking up at Nikaido with eyes that tell him that's exactly what he wants.

Nikaido decides there's been more than enough distraction already, and presses his thigh between Senga's legs, making him arch beautifully and Nikaido smirks at how hard he still is.

“Been dreaming for weeks was it?” He can't help but ask, even though he hardly ever initiates conversation, in and out of bed. But he likes Senga's voice, likes the way dirty sounds fall from his lips, and he's a little curious what kind of person Senga is to agree to this.

“Yeah.” Senga agrees breathlessly, shamelessly, wrists flexing as if he wants to break his hands free but can't. “Last time... Was the hottest thing I've ever had done to me.”

Nikaido doesn't answer, keeps his face unimpressed, but the words fuel his arousal, and his interest in this boy.

Senga glances up at him when he doesn't answer, rocking his hips against Nikaido's thigh to get some friction. “But I guess people tell you that all the time...”

Nikaido leans down to bite at his earlobe again, definitely used to dirty talk but not exactly to compliments, and hisses against his skin. “Just shut up and take your clothes off.”

Senga shudders beneath him, and when Nikaido's hands release his wrists he immediately pulls his gloves off and then starts unzipping the vest. Nikaido draws back to let him sit up and remove it, and he shifts enough to lean against the headboard of the bed, watching Senga's skin get exposed.

It's always different bringing them home, not the same atmosphere and filthy feeling, but it has its advantages too. Getting them naked for example, and hearing every sound they make without distraction.

Senga's strong, Nikaido can see, his muscles evident but not obvious under smooth skin as he lets the vest slip off, arms and abdomen most prominent. It looks good on him, fits him well, and even though Nikaido's not too into muscles normally, he has to admit that the flex of Senga's arms as he undresses turns him on.

When Senga's topless, he hesitates a little with his hands on his belt buckle, a hint of shy underneath the arousal, making him look his age. Nikaido's not sure what feeling the image evokes in him, but it's a good one, and he raises an eyebrow at Senga, urging him to go on.

Senga bites his lip and he undoes his belt, slowly, but he looks Nikaido in the eyes as he undresses, and Nikaido can barely hide his smirk at Senga's determination not to disappoint.

He certainly doesn't, pulling his zipper down as slowly as if he's doing a striptease, and when Nikaido shifts a little Senga takes the opportunity to break eye contact, instead letting his gaze run all over Nikaido's body in anticipation.

Nikaido doesn't bother hiding his smirk when Senga licks his lips and slips a hand into his own open pants, pressing his palm against his clothed erection and moans, eyes falling shut.

“Hey.” He says, tired of waiting even though it looks amazing, and he can't help but wonder how far he could make Senga go while just watching. “Loose the pants and get over here.”

Senga lets a tiny sound slip at that, and Nikaido realizes that it's just his voice that gets to him like that, but then Senga obeys, shoving his pants and underwear down and shifts to pull them off, leaving him completely naked. He doesn't seem very embarrassed anymore, and Nikaido looks him over appreciatively as he crawls closer, settling right before Nikaido.

“You're not undressing?” Senga asks, but it's a soft question, one he seems to already know the answer to, and he leans forward as if to brush his lips against Nikaido's, but stops two decimetres from his face.

“No.” Nikaido answers, and Senga's eyes seem to darken with another wave of arousal. Nikaido digs up the lube he has in his pocket and hands the small bottle to Senga, who accepts it with wide eyes. “You know what to do. Don't take too long.”

Senga's quick to cover his fingers in the substance and slip them between his legs, and Nikaido sees on his face when he gets the first one inside, his mouth falling open on a heavy breath and his eyes almost closing.

It looks fucking hot and Nikaido can't help but shift before he reaches down to his own pants, undoing his belt and the button of the jeans, catching Senga's attention with the sound.

It would look funny how Senga's eyes widen as they lock to his hand that's pulling down the zipper, if he didn't look so good. Senga's attention makes Nikaido feel attractive in a way he's not used to, almost adored, and even though he knows he can look hot, he doesn't get the kind of look Senga gives him very often.

Nikaido shoots Senga a glance with an eyebrow raised in questioning amusement, but Senga keeps shamelessly looking as Nikaido slips a hand inside his underwear and strokes himself slowly. It's Senga who moans, unexpectedly, but the noise sounds guttural and Nikaido's sure he pressed against something good inside himself, even if he still follows the movement of Nikaido's hand.

Nikaido gives Senga a few more moments, but when he keeps breathing a small moan on each exhale, Nikaido decides that Senga's ready, mostly because he can't wait anymore.

He raises a hand to grab Senga's wrist, the one moving between his legs, and Senga gasps.

“You're ready.” Nikaido says, and Senga shudders, not seeming opposed to that statement at all and he withdraws his hand and crawls into Nikaido's lap without any prompting, straddling him.

Nikaido breathes a small laugh against the skin of Senga's shoulder, intrigued by how eager Senga is as he shoves his own pants down enough to roll on a condom. Senga squirms impatiently on top of him, little frustrated noises escaping him as he tries to reach down and help Nikaido, but his hands are slapped away.

Nikaido thinks about scolding him, but then Senga's skin looks so tempting before him, tanned and with a sheen of sweat over it, and he ends up biting at his shoulder instead of reprimanding him verbally. Senga groans, but the sound trails over into a whimper when Nikaido positions himself with one hand and grabs Senga's hip with the other, wasting no time in urging him down onto his cock.

Senga's hands come up to Nikaido's clothed shoulders as soon as Nikaido breaches the first resistance, and they twist into the expensive fabric hard enough for Nikaido to shiver. Senga's so tight, just like the last time, and Nikaido sets both hands onto Senga's hips when he's halfway inside, leaning forward to speak into his ear.

“Now you take over.” He demands, voice low, and he feels Senga's erection jump against his stomach.

“Yes...” Senga agrees almost unconsciously, his voice breathy as he's entirely focused on sinking down further on Nikaido's cock, eyes falling closed.

Nikaido watches his face, how his brow tenses and then relaxes as he successively takes in more, looks at his plump lips that shine with saliva, and Nikaido has to bite his own lip to stifle the urge to kiss him. He's not sure what's going on with those urges since he doesn't even really enjoy kissing.

When Senga's finally the whole way down, his eyes open, and they're so dark something hot sparks within Nikaido and his hips snap up in a small thrust on their own. It causes Senga's mouth to fall open on a whine that might be a slight pain but mostly pleasure, but then he starts moving, pushing himself up before sinking down slowly, way too slow for Nikaido's taste.

He's not entirely inconsiderate though, giving Senga a few more moments to move at his own pace, until he's sure Senga's only doing it to tease.

“Faster.” He orders, and Senga's breath catches in his throat, hands on Nikaido's shoulders letting go of the shirt to hold onto his body instead, and the hot touch on his shoulders has Nikaido exhale a shaky breath.

He's not very loud normally, not even with Rina whom he normally has no inhibitions with, and so the groan he lets out when Senga starts to roll his hips with purpose surprises even himself, and he can feel how much Senga liked that with the way he tightens around him.

It looks so damn good, the way Senga rides him just like he promised on the dancefloor, only hotter, with how there's a small drop of sweat running down his throat, over his collarbone, how his skin is flushed and how his breathing is laced with small noises of pleasure.

Nikaido can't wait very long before using his grip on Senga's hips to pull him down at the same time as Nikaido thrusts up, and Senga's fingers dig into his shoulders hard as he arches and moans. Then suddenly, he says a name.

“Ah, Takashi...” He gasps, quietly, and again it seems to almost subconsciously, but it fuels a rage to rip through Nikaido's body, and before he knows it he's slapped Senga straight across the face and pressed him down against the mattress, hands holding his wrists hard enough to restrain the bloodflow.

He figures Senga heard his name when Rina moaned it, but it gives him no right to use it, no right to even remember it.

“Don't you ever say that again.” He growls against Senga's ear, and his voice sounds dangerous even to himself.

Senga whimpers, struggling a little against the hold on his wrists, tears of pain at the corners of his eyes from the slap, but when he looks up, his gaze is heavy with arousal and his erection is if possible even harder, dripping onto his stomach.

Nikaido growls at how the message doesn't seem to have come through entirely, and changes his grip a little on Senga's wrists so that it doesn't stop the blood but is still tight, before giving a thrust hard enough to make Senga slide a little on the sheets.

It feels good, too good, adrenaline from the sudden anger still rushing in Nikaido's veins and heightening every sensation, and he knows he won't last long if this goes on, if Senga keeps arching and moaning breathlessly, feverish eyes falling closed every other second like he can't keep them open.

Nikaido fucks him as roughly as he can without coming instantly, determined to make Senga feel this for days, making sure it's nearly painful but not quite, and Senga's squirming beneath him, seeming uncertain whether he wants to push back or move away.

It looks fantastic, and when Nikaido glances down he sees how hard Senga is, how he must long to touch himself since he's probably been hard since he got off the dance floor.

His suspicions are confirmed when Senga tries to tear his hand free from Nikaido's grip and whines when he can't, glancing up at Nikaido helplessly and it's hot.

Nikaido leans down to speak in his ear, both to hide his smirk and because he enjoys the way Senga shivers at the hot breath.

"You think you've been good enough to come first?" He asks, voice low and challenging, and Senga whimpers, his whole body tensing at the words.

Nikaido's smirk widens as he realizes exactly how much Senga gets off on hearing his voice. "Because I don't think so."

Senga just moans, sounds rising in pitch as he clamps down tighter around Nikaido every time he pushes inside, and the thought passes through Nikaido's head that he may be able to come untouched.

The mental image sends a hot wave of arousal through him, and a small sound slips from his lips, one that he could normally disguise, but it's impossible when his mouth is just by Senga's ear, and it makes Senga's next moan louder.

Nikaido relishes in it, in whispering small filthy words in Senga's ear while pounding into him, in hearing and feeling him react until he's almost crying in frustration. It fills him with the kind of power that inevitably gets him off.

When he comes, he doesn't bother containing his groan, breathes it into Senga's skin as he shudders in pleasure, and when Nikaido can open his eyes again after a couple of moments of bliss, he can see the goosebumps on Senga's neck and the rapid beating of his pulse underneath his skin.

"Please...?" Senga asks, voice small and breathy, and when Nikaido releases his wrists and pulls out, one of Senga's hands immediately wraps around his own erection and the other gets into Nikaido's hair and tugs him back down.

For a second Nikaido's certain that Senga's going to kiss him, and terrifyingly certain that Nikaido would let him, but Senga's lips press against his cheekbone, then continues down his jaw and throat, nosing his collar aside to get access to more skin.

It's heated and desperate and Nikaido doesn't protest, still thinks about whether he should protest when Senga comes, crying out against Nikaido's neck and spilling hot over his own stomach as the fingers in Nikaido's hair tighten so much it hurts.

It's only for a moment though, before Senga detangles his hand with what seems like some difficulty with coordination.

There's an angry red mark around Senga's wrist, Nikaido can see, but he doesn't feel bad about it. Quite the opposite.

He sits up, running a hand through his hair to get it into some kind of order, and looks down at Senga trying to catch his breath through shiny lips, one cheek pink and the other still red from the slap. He's pretty, and Nikaido doesn't normally use that adjective on men, never thinks it fits, but right now, it does.

"Wow..." Senga breathes, and even though Nikaido doesn't move a face, he internally agrees. He feels warm and relaxed, and that's more than he's done the last couple of weeks.

He just looks for a little longer as he calms his own breath entirely, wanting to scratch away the feeling of Senga's kisses on his neck, but doesn't reach up, lets the tingles continue to heat his skin.

He stands slowly, discarding the condom and zips up his pants before heading over to his wardrobe, opening one door and tugs a simple dressing gown from its hanger.

He walks back to the bed, and Senga slowly sits up.

"The bathroom is down the hall to the right. The front door leads to the street." He says, and Senga takes the hint, smiling faintly as he accepts the dressing gown.

"Thank you." He says, then hurries to slide it on and gather his clothes.

He gives Nikaido a final, heated glance that Nikaido has no idea how to interpret, before slipping out the door that's slightly ajar and closing it behind him.

Nikaido thinks about the look for a few seconds, but then something else reaches his mind. He closed the door when they got here, and now it was open.

He can't help but smirk a little, hoping Rina enjoyed the show.

She stands from the couch when he exits her brother's room, wearing one of Takashi's dressing gowns, his hair mussed and his own clothes in his arms. He closes the door and freezes with the hand on the handle when he sees her, but only for a second, before he slowly starts walking towards the bathroom, still looking at her.

It's not like she doesn't know her brother sleeps with others than her, not like she didn't fucking bring this guy here. But they're always so submissive, or a little confused, so something that Senga isn't and it doesn't settle well with her.

He's demanding but in a submissive way, and she could tell that he threw her brother off guard a couple of times, even though no one but her could probably tell since it was only a matter of seconds every time.

Senga stops just before he walks past her, gazing at her questioningly, eyes dark and one cheek glowing red from the slap he deserved.

"I'm the only one who can say his name." She says, voice almost toneless, but she's sure her message comes through. Don't get too cocky.

"I know that. He's hot when he's angry though." Senga says, and his voice is calm enough that she can't do anything but raise an eyebrow at him. "I like him. Let me come back?"

She enjoys how his voice turns a little pleading, and a small smug smile spreads on her lips.

"Depends on your behaviour." She says, playing with him, back in control the way she likes it. "I'll think about it."

He nods with a small smirk, but doesn't say anything else, just walks past her towards the bathroom.

She looks after him and can only think of how he made her brother moan, wondering if that's what you learn when you work at that kind of club, or if it's just him.
