✫ synopsis ;; when you agree to attending a kickback with the worst people you know, you're not expecting to end up alone in an apartment with your roomates best friends. you'd always suspected there was more to them.

but nothing could've prepared you for what you end up learning.

The devil takes two forms.

A blonde with blue eyes, and a brunette with striking green ones.

Mikasa vies to call you dramatic, shuts your comments down with a reminder that you have a natural inclination towards theatrics. You argue that she wouldn’t understand even if it hit her in the face. That the version of Armin and Eren that exists to her only can exist to her, because the three of them have been attached at the hip since birth. You don’t blame her for insistence that her friends are friendly people.

But it doesn’t slip you by. Her hesitant voice, the lack of conviction in her voice when she expresses this thought to you. You can see it in her eyes, the way her lips press together, the soft furrow in her brow. Like she’s debating the ethics of her words, her lack of confidence is astoundingly obvious to you.

Yes, there are plenty of things that Mikasa has been right about before. She’s a smart girl. Careful, considerate, bright - but her friends are her achilles heel. Of all the things you like about her, he friends tend to be bottom of the list. Her rose colored glasses seem to outweigh her rationale. She’s almost convincing, a silent but soft plea to her words. Gives you her most earnest expression, holds your hand tight enough that your heart races.

“They’re nice people, Y/N.”

You always reply the same, patting the hand that holds onto your forearm as you walk back to your dorm room. Smiling gently at her and attempting to hide your obvious disagreement. You often leave it there, moving on to something more relevant and more interesting before getting ready for bed.

It’s not that you think Eren and Armin are bad people.

They aren’t. At least, not in the way that you think they’re morally reprehensible. They’re not fuckboys or assholes (though Eren has his moments) and they’re good to Mikasa. Good to the people they consider friends but cold to what they consider to be an outsider. If Mikasa hadn’t declared you her friend, you’re pretty sure you would’ve already been thrown to the piranhas but you try not to think about it.

Eren and Armin are.. complicated…? Interesting? You’re not sure what the words are.

You think carnivorous might be a good word. Meat-eaters, almost predatory in nature. Whenever you’re in a room alone with them, you get this sinking feeling in your gut. It goes away when Mikasa or Jean or Connie or anyone else in the group accompanies you. But only then.

When you manage to end up alone with them for even 10 minutes, you feel that instinct. A swarm in your gut that claws all the way to your throat. Your heart races, palms sweaty, mind hazy. You’re at risk of something with no name and no origin. Something that has blue eyes and green ones, and hands that always form fists before they outstretch to shake hands.

You’ve spent countless nights giving these instances rational explanations. Talking yourself into circles until it makes sense. You want, more than anything, to understand what the fuck those two are up to.

But, you always fail. Always. Because Eren and Armin (and Mikasa though not in this specific instance) speak languages you can never learn. Body language cues, silent comments, almost like they’re reading each other's minds. It makes you ill to think about.

Outsider. You have always been an outsider to this group of people, who grew up in the same area and went to the same highschool and now in the same college. You’re only here for university, and it was only by accident you’re around them. Every time you’re in a room with them, it’s made clear to you that they still don’t know where to fit you. And while everyone else coaxes you with nice conversation and inclusion, those two hardly feel like affording you that luxury.

You feel it. All over your skin, like a prickly and itchy thing. They size you up. Of course they’re nice about it. Eren asks you what your life was like, and Armin smiles at your jokes. They’re so good at it that sometimes you find yourself wondering if you’ve imagined it, and that your anxiety has turned them into some kind of monster in your proverbial closet.

But there’s always a halt. The initial inertia has started to wear off and Armin gives you a sickly sweet smile. It’s always tonal, always miniscule. But it’s there, that moment where they start to look at each other with confirmation and you almost miss it. If you blinked you might, but you’ve seen it. Enough times that it makes you certain. Danger is lurking there, murky waters surrounding the very being of them.

The blue in Armin's eyes and the green in Erens are cut from the same cloth. Of ocean water, deep beyond reasonable doubt or of vast universe and unreachable sky Unexplored, unmarked territory that is waiting for you to get too close just so you can run out of air. You’ve always been afraid of distancing yourself from the ground, too far in either direction. Drowning deep in ocean water or losing yourself to something as grand as the sky, endless. You know yourself, your vices about exploration.

And, you’ve always been curious about the unknown.

__

The skirt of your dress rides too high on your hips. The thin material of stockings rub against your skin, sending a chill up your spine. Two bottles of liquor are pressed to your chest, snugly in your elbow as your other hand comes up to knock on the door. Your nails are freshly done, makeup painted by one of the girls in your dorm. You’re more aware of your appearance than you like.

You knock three times, with your fingers curled into your palms. When the door swings open, you’re greeted by Eren and Armin together.

Eren’s hair is long, a little above his shoulder and tonight it’s in a half-up half-down style. He’s wearing a flannel button-up over a black-tshirt that’s tight to his skin, gray skinny jeans and vans. Armin is wearing a sweater vest over a white button-up, fitted chinos, and white slip-ons. They both look like something out of a movie. You can’t help but feel overdressed, your hands subconsciously pulling on the end of your skirt. Your heart nearly drops into your stomach.

You hold the liquor bottles up first.

“Hey, uh…”

You look over their shoulder and find nothing and no one. The time is well into when the party starts. You knew Mikasa wasn’t here yet, but she had promised you she’d be there later. You were expecting the usual cast of bandits. Jean, Connie, Sasha and maybe Reiner, Bert and Annie if they felt up to it. Your brows furrow softly, looking at the both of them. You pause, stepping back slightly.

Eren steps forward, mouth curved in a slight grin. Your heart is hammering against your ribs, in your ears. Your mouth feels cottony, in a slight tremble.

“Where is everyone?”

Armin moves, steps between you and Eren. He gives you an apologetic smile. You don’t look him in the eyes, his palms sliding down the front of his pants.

“Ah.. so actually, Mikasa helped us set this whole thing up.”

You feel it again, clawing at you. Your eyes widen, and you step back again. Eren reaches for you, grabs the liquor bottle out of your hands. He gives a look at the label, a canine poking out from his lips.

“Woah, these are kinda pricey. Were you thinking of us? How kind of you”

The weight of his words doesn’t go unnoticed. Not by you, or by Armin who gives him a shove with his elbow. He rolls his eyes, but takes it from you without any more teasing. Armin coughs into his hand, smiling.

“Set.. what..up exactly?”

Armin’s eyes flash with something you can’t grasp and he shakes his head. They look at each other again before Armin turns back to you.

“Why don’t you come in, first? We can talk about it.” He insists. You cross your arms under your chest. You’re uneasy, body stiff.

“I’m.. good. I thought this was gonna be a party, but I don’t think..”

“Don’t be a stranger. You think Mikasa would let us hear the end of it if we hurt her cute little roommate?”

There’s something there, in the tone of Eren’s voice that makes you flinch. You don’t know how to describe, don’t even know what it is. It’s sarcastic, a caustic roughness in it that makes you frown.

“You’re a guest of honor tonight. We just want to get along with you. Please, come in.”

Armin looks at you with his eyes. They’re a sparkling blue, but murky. Unclear and unsteady. Rationally, you should leave. Your mind is telling you that much, itching to turn on your heel and take an expensive Uber home. You’re cold, in a place you rarely visit, with people you don’t exactly trust. People you’re off put by.

Armin is smiling like someone might before taking a picture, pleasant and ephemeral. Eren is looking at you with too much honesty, hunger you can’t shake. You feel like you’re lost in the woods, you feel out of your element.

You should leave, you should leave.

But you don’t.

Instead, the cold air brushes your hips. You pull your dress down and rub your hands over your shoulders and step inside. Armin steps aside to let you, and you mumble under your breath.

“I’ll leave soon enough. It’s just fucking freezing outside.”

They glance at each other over your shoulder. Of course you catch it, but for your peace of mind - you ignore it. Instead, you walk with Armin who directs you to the living room. The room is decorated for a party - fairy lights and streamers and the likes. Which is especially odd to you. You sit on the couch and Armin sits diagonal from you in a little love-seat across the way.

“Ah.. the decorations. We were planning on having a party, but everyone wanted to go bowling instead. So, Mikasa set this up for us.”

Eren comes from seemingly out of nowhere. He doesn’t sit on the couch, instead finds himself on the arm of Armin’s chair with three glasses in his fingers. He flips them up.

“Want something to drink?”

You stare at them both. The image of them together doesn’t bode well. Your fingers go to mess with a thread of fabric on the couch, biting something back. Curiosity killed the cat, or whatever they say.

“No, thanks.”

Eren’s jaw clenches just slightly and Armin puts a hand on his thigh. Armin smiles at you, again. You don’t like it, and you don’t like the way they feel. This parade, this facade. You aren’t sure why you don’t. You know they haven’t done anything wrong.

But there’s this sickly feeling, disingenuous. Gluttonous, maybe. Something. You want to get to the bottom of it, and you want to do it quickly. Why is it directed at you? What’s the intent?

“Someone’s nervous.” Eren comments slickly.

“Most people would be if they suddenly had to hang out with some guys they’re kinda acquainted with, alone. In the middle of the night.”

You sound more snippy than you mean to, but decide not to apologize. Eren raises a brown, blase but amused.

“Feisty.”

You blink at him incredulously. Armin looks like he’s assessing the situation, like always.

You’re preparing yourself to leave, steeling your nerves. Anything is better than this tension, these nerves. This uneasy feeling, but before you can - Armin is laughing slightly under his breath.

“You’re really interesting.”

You blink. Breath catching in the back of your throat, you stare with your mouth open in slight shock. Armin flashes you a smile.

“It normally takes people a while to catch onto me and Eren.”

An admittance, a confession, a confirmation - something. You can hear your blood pulse through your veins, spitting out a quick reply.

“Really? You two are pretty obvious.”

They look at each other and Eren laughs a little. Armin does too, more airy. There’s something like an alarm going off in your mind. An unidentified emotion, a soft and subtle panic. You swallow something in your throat and wish you had something to drink.

“It’s nothing bad.” Armin promises. He gets comfortable in the chair, and Eren decides on pouring himself a drink. A little bit of liquor into a glass, he swishes it around and sips on it silently. Armin looks contemplative, like he’s trying to figure out what to say.

“We’re not bad guys or anything, yknow?”

“At least not in the way you’re thinkin’.” Eren interjects.

“What the fuck is your guys deal, then?”

“Nothing, really. We just.. like the things we like. The same things, normally. We’re actually pretty similar, in some ways,”

The look on your face must be as confused as you feel. You’re fucking lost. Beyond lost. You stare at them for a long time, unsure of what to ask. Eren is mostly tuned out, and Armin is silently waiting for your interrogation. He knows it’s coming.

“Explain yourself or I’m ubering home.”

Armin laughs again, scratching his chin. It terrifies you, just slightly - how someone so aware and so.. whatever he is can look so angelic. So lighthearted and trust-worthy.

“It’s not anything to explain, really. Me and ‘ren just like the same things. We have since we were kids so whenever we want something, we.. work together to get it? Watching R-rated movies, getting toys, etc.,”

There is no way this is going where you think it is.

“It’s the first time it’s been over a person, that’s all.”

Holy shit.

“A-are you talking about me?”

This makes Eren burst out into laughter. A full blown laugh, enough to make him put his drink down. Armin looks over at him with a smile.

“No fucking shit.”

“Be nice to her, Eren. She was scared of us, yknow?”

You really, really don’t know how to feel. An overwhelming mix of emotions is making you feel like you might pass-out. Your hand goes up to your forehead, your eyes clenching shut as you try and understand the implications. There’s more to this, you know that now. There’s always more, and your gut hasn’t failed you at all.

“So what then? You want to.. fuck me, I guess. But why me? And why were you two acting so.. fucking weird about it?”

“We didn’t mean to scare you, you just happened to catch on. To me and ‘min. How we act around Mikasa, all of it. We just wanted to test how much you knew.”

“And we like to make sure if something we want is worth the effort. If you couldn’t figure out what wavelength Eren and I are on, it would’ve been a waste.”

You don’t miss the want. The implication of keep. Your mind feels heavy.

“...What do you mean by want?”

Armin grins a little.

“You’re really clever, yknow? I can see why you’re here on scholarship.”

Eren takes a sip of his drink, taking a deep breath.

“We don’t do the whole fuck and leave thing. We wanna keep you.”

“Like date me?”

“Sure. If you’re cool to call it that, sure.”

You blink at them incredulously. Your mind runs a mile a minute. You lean into the couch and take a minute to process everything. It’s troublesome. Your skin feels slightly warm. You close your eyes, and you think of Mikasa. You don’t want to doubt the person you feel closest too but you can’t help but question everyone’s intention. You still feel like you don’t know anything.

“Are you.. two? Or three, I guess - are you guys dating each other?”

Armin looks at you surprised. Shocked at your deduction. He nods slightly.

“We’re all each other’s. Mikasa doesn’t really like breaking the ice and she’s a little slow on the uptakes about her feelings for other people, but you like her right? Enough at least.”

You’ve never thought about it in-depth. You don’t know how to feel about it, but you know now. Why Mikasa seems so eager to make sure you like her friends. Why she hesitates in some ways but not others. Everything falls into place. You sigh like you’ve run a mile. It’s not that surprising. You’ve always felt something was special about their dynamic, specific and unique. It’s always struck you as odd, but you had always been the intruder. Who's to say you know what’s best?

But it’s been confirmed to you, your suspicions about it. That feeling you get in your gut. Eren and Armin have always seemed awfully possessive of her anyways, you figured that maybe they’d just resnted you.

Without a shadow of a doubt, nothing could’ve prepared you for this. For this outcome, above any other one. You feel like you might wake up from all of this, broken out in a cold sweat. Like this is some kind of sick and strange dream. You lay in the silence for a few minutes.

“What’re your intentions with me? With this?”

“Pretty obvious we wanna fuck you.”

“Eren! Don’t be so gross.”

You stare at them stupidly.

“What the fuck..”

“Mikasa was nice enough to send you this nice little get up. Can’t blame us, can you?”

You cup a hand over your mouth.

“Oh my god. You guys are insane.”

Eren shrugs, and Armin laughs.

“You’re welcome to say no.” Armin says. It’s genuine, and gentle. It’s comforting to know they have some limits, some boundaries. Eren gives you a wolfish smile, finishing off his drink and wiping the back of his mouth.

“But if you do say yes, it’ll be good. We’ll make it good.”

The ocean is wide, and vast. Above all, it’s tempting. It’s only natural to want to explore it, inquisitive. Human nature always is like that. This time they don’t look at each other, just at you.

You close your eyes and jump in.

“...Sure. Yeah.”

__

Eren and Armin play off of each other so naturally, part of you wonders if they really can read each other's minds. Even after everything.

They direct you to their bedroom, a single king size mattress in the middle of it. There’s a TV attached to the wall, a PS5 and games in a cabinet. Horror movie and pin-up posters next to vinyl records and succulent plants. They told you they were similar in some ways, and if you’d only just seen this room you would’ve laughed in their face.

But, like this - with Armin and Eren hovering over you with eyes lidded and hands practically twitching, you think you’re starting to understand. The thing they share isn’t taste, but hunger. The same kind of wretched animal of want, it’s desire. They both feel it equally deep, and when it’s towards you, you start to understand where your fears are coming from. You’ve climbed into the maw of the beast, unhinged it’s jaw with the hands of curiosity and left yourself in its mouth. Hot and heavy, aching to swallow you whole.

They sit next to each other indecisively, and you lay in their bedsheets. You’re beyond nervous, heart beating wildly.

“We’ve been waiting for you for so long.” Armin says. His hands are pretty, thin and nimble fingers. You catalog what you know about him. Armin Arlert, 20-something, pianist and art-history major. You squirm as you feel the pads of his fingers trail on your calf. Something warm runs through you, your mouth opening only to close. Armin lets his hand continue to caress you, feather light through the sheer material of your tights. Your breath hitches.

“Wanna fucking ruin you. Christ,”

You let out a whine, not meaning to. Your hands cup over your mouth. You’ve always had strong feelings for them, normally visceral. The sudden redirection to lust is hard to cope with. Eren scoffs lightly at your neediness. It’s not intentional and you’re not sure how you’d go about getting it under control.

“Be easy on her, Eren.”

“Still playing good cop, ‘min?”

Armin smiles at that.

“It’s fun.”

Eren rolls his eyes slightly, but he’s focused on you hard. Armin is watching you too, waiting. You let out a shaky breath. Armin directs you to sit up. You do, sitting up on your knees. Your skirt rides up, but you don’t get a chance to pull it down. Armin shifts, the bed creaking under his weight as he gets behind you. His hands secure themselves around your waist, fingers tugging the fabric slightly. He drags you back until your back is pressed against his chest. His chin goes over your shoulder - breath dancing your neck. You twitch lightly at the contact. Too light, but invasive still.

“Eren is impatient. Kiss him first, then me, okay?”

You let your head fall onto Armin, just slightly. Eren inches towards you on his knees. You get more of a feel for him this up close. His eyes, his lips, a cupid's bow and strong jaw - strong brows too. Eren is handsome and pretty, all at once. His hand cups your cheek, thumb brushing your lower lip. He tilts your head back slightly. He has rings on his fingers, and the metal feels cool against your skin. Strong hand comes around the base of your throat, fingers on your pulse.

“So fuckin’ nervous, baby.” He teases, lips brushing yours. Slightly chapped, full but forceful. Your mind immediately blanks. “Such a smart girl and you’re all skittish over being fucked”

You choose to ignore his comments, instead letting Eren kiss you. His mouth is awfully hot. Eren doesn’t hesitate in making it deep. He practically forces your mouth open. The sticky heat of Eren’s tongue in your mouth is making you lose balance. His teeth, his lips, and the hand on your throat. All of its possessive, rough. If Armin’s hands weren’t carefully touching your body, groping slightly through your clothes - it would feel like you and Eren were the only people in the world.

“Time’s up, ‘ren.”

Eren pulls back. For good measure, he spits into your mouth and he tastes like liquor. He closes your mouth up with a smile.

“Give that to Armin for me.”

Your eyes go wide. Armin chuckles behind you, before tilting your face to one-side. Armin kisses you softly. He sucks on your lips and tongue, takes the spit out of your mouth. It’s messy, drool spilling lewdly down your chin until it drips down your neck. Armin’s kiss makes you whimper, needy but mean. Something cruel about how he drags it out. Eren groans, cupping his hard cock through his jeans.

“Fuck, that’s hot.”

Armin pulls away and presses a kiss to your cheek before Eren leans forward. You watch as they kiss each other easily, over your shoulder. Something throbs between your legs. You suppress a strangled whine as you see it in front of you. You think of how often they must do this, touch each other. Touch Mikasa. You feel so fucking dirty for picturing it, how turned out it makes you.

“You like picturing us together? Us and Mikasa?”

Eren is quicker than you expect. Maybe you’re just too obvious. You nod dumbly, unsure of how to reply. Eren presses a kiss to your jaw.

“You’re so cute.” Armin coos.

“No wonder Mika likes you.” Eren muses. You shiver slightly when you feel Armin’s fingers hook into the skirt of your skin-tight dress.

“Should we send her a picture?”

Your eyes widen.

“Probably nothing she hasn’t seen before. Mikasa is just shy.”

They talk about you like you’re not there, yet somehow - all of their attention is so solely on you. Armin slowly peels your dress up. You stand on your knees to make it easier, and a whispered good girl brushes your skin. Eren watches with a hawk-like gaze, in front of you in the same way. His hands reach forward and squeeze your hips. His fingers bury into your thighs through your tights.

“Fuckin’ hell.” Eren curses. You wince slightly. Armin’s hands part your thighs. He grabs your ass with little hesitation, pretty palms massaging and rubbing the skin. Eren kisses you all the while, and you aren’t sure which thing you’re supposed to be focusing on. It becomes clear quickly that it’s Armin when you feel his hands sneak around your thighs, two fingers rubbing lightly on your clit on the outside of your clit. You twitch, pussy growing wet at even the smallest of gestures. At the flick of Eren’s tongue, the way he bites your lower lip.

At Armin who pets and strokes and caresses your waist and hips through your clothes. Yet to touch any of your bare skin, simply teasing and waiting. You squirm endlessly, desperate for something more. Your voice feels wobbly.

“S-stop teasing me.” You say.

You try to sound intimidating but your voice warbles. Eren laughs lightly at you, teeth nipping your jaw as his hands wrap around your throat. You blink up at him lightly, green eyes intense and focused. He smiles down at you, a head taller than you.

“We’re taking our time, that’s all. Don’t think you can take our dicks without it. Unless you like being stretched out?”

You shiver every time Eren opens his mouth. Normally his vulgar way of speech makes you want to knock his teeth in. Armin laughs from behind you.

“Think you nailed it, ‘ren.”

“That so? Does the idea of our dicks stretching you turn you on? Don’t lie to us.”

“I-it doesn’t -”

“No? When Armin takes your panties off, what’s he gonna find then? You’re gonna tell me you’re not gonna be fucking soaking?”

You whine again. Eren grins against your mouth, lips your lip and bites it. He’s so goddamn possessive, so annoying. So unbearably hot, it makes you sick.

“It’s okay if you want us. We want you, too. All three of us thinking about how fucking good you’d look taking dick. Which position you’d look best in, how fucked out you get.”

You shudder, again and again. Armin is a silent killer, quiet but dangerous. He knows all your cues already. When Eren says something that really gets you hot, he applies the gentlest pressure to your clit. Still clothed, he works you up so easy. You’re feverish already, but Eren has yet to finish his tirade.

“Smart and clever girl like you deserves to get pounded into the fucking mattress, right, ‘min? To get fucked all stupid and relieve some of your stress”

“Of course.” Armin agress.

You’re absolutely speechless. Turned on out of your mind, you nod your head softly.

“Fuuck.” You groan.

“There you go, stop thinking so hard. Just let us do what we wanna do.”

You sink deeper, falling into them. Your hands go onto Eren’s chest, splayed your fingers and steadying yourself as Armin touches you. Eren presses his lips to your forehead as you hold onto him, clinging to his shoulder. You’re much easier than they thought you’d be, and Eren figures maybe it’s because you had been so hesitant in the first place. Maybe you were just as twisted as he’d hope.

Eren likes you just as much as Mikasa and Armin do, but he hardly fights his aggression towards you. His hands reach underneath your dress.

“Arms up.”

You manage it weakly. Armin holds your waist and stares at your silhouette. Eren is rough with everything, though you don’t think he means to be. Maybe eager is a good word, the way he tugs your dress off your body - like he’d rip it apart for getting in the way. He balls it up and tosses it across the room. His eyes lowered, a growl ripped from his throat as ringed hands launch forward. Goosebumps appear over your skin as Eren gropes you. Squeezes your tits and twists your nipples with unfiltered excitement, watching the way you throw your head back lightly at the gesture. Pleasure sends you reeling.

“You’re real sensitive.”

“So what if I am.”

“It’s cute when you’re feisty.”

It’s Armin that time. His word always feels like law, always feels well-thought out. Not like Eren who just likes to speak his mind, Eren who doesn’t think all that hard about what to do next. Armin thinks of you whenever he decides to say something. His eyes rake over your face, a pretty smile and eyes that are nervous. He doesn’t look like it, no traces of evil in his full lips and straight lashes. When they were little, Armin used to pick the leaves off of flowers one by one. Eren always thought it was weird.

But Armin has always been classical - recognizes the beauty of taking things apart. Down to their broken essentials, pressing them to keep them safe. Armin can’t help but want to take this time with you.

Armin puts his hand between your thighs and pinches the fabric of your stockings before tearing them right at the seam of your crotch. You gasp slightly, the sudden rush of cool air fanning against your clothed and sticky cunt. It sullies you. You feel dirty to be exposed like that.

“You better pay for those.”

Armin doesn’t say anything. Just smiles, kisses the small of your back as he rubs his two fingers up against the lace of your panties. Lavender and fitted tight, they stick to you. Armin feels how soaked you are, the mess you make when your hard clit peeks through the material. Eren kisses you and touches you as a distraction, a growing addiction to the soft feel of your skin. You’re softer than they expect, warm under his calloused palms. Eren feels like he’s always learning new things from you. It’s a lot at once. Eren on his knees in front of you and Armin on his knees behind you, touching you in different ways and at different paces. You can’t help but feel like you’re being taken under the tides, the way Armin parts your legs and plays with your pusy. The way Eren gropes your body. Somehow it works perfectly in making your mind melt. All you can think about is how badly you want both of them, both bodies, both sets of hands and mouths.

It makes you feel greedy, being able to indulge so easily on their touch but you can’t help yourself. Your body’s natural response to Armin is to spread your legs for Armin when he asks, to tilt your head back for Eren to nip at your throat with his teeth. You’re a sacrifice at their altar, a willing victim and you like it. It scares you how much you like it.

You let yourself succumb to it. To Armin who rubs your clit sweetly, to Eren who covers your neck in bite-marks and hickies, slowly inching his way to your chest. You let yourself take, more willing than you ever meant to be.

“You’re so fucking beautiful when you’re losing it.” Eren says, hisses it under his breath and against your throat. Armin chuckles.

“Right?”

“I don’t even know where to start with you, damn tease. Making us wait for all those months.”

“Eren just wants to shove his cock in you, he’s reckless like that.”

Armin slips his hands into the front of your panties. A spark of electricity runs through your entire body when you feel him rub around your clit. Teasing your folds with his nimble fingers, his middle finger sliding over the sensitive nerves every now and again. Eren watches your expression eagerly, listens to your breathy little moans. He’s watching you get off on Armin’s relentless teasing.

“See? How Eren’s watching you?”

Armin's other hand cups your jaw. You take Eren in. How he undresses, down to his pants. Your eyes widen as he unzips his skinny jeans, and when you look up - you realize he’s teasing you too. Making you get off to him, he’s so slow. You soak in his body, the tone in his stomach and the deep V of his waist. Tan skin and slight hair. His cock, heavy and hard in his black boxers. He palms it, swearing under his breath. Your eyes are glued to the outline. Armin keeps you steady, sets the pace slow as wetness continues to grow. You’re so turned on you feel like you could die.

“Do you wanna see his cock, pretty girl?”

A whine leaves your mouth. Armin presses a feather light kiss to your pulse.

“Tell him.. go on. Don’t be shy.”

“I want to.. shit - wanna..”

Your whole body breaks out into a flush, humiliation flooding your system. Armin coaxes you by rubbing your faster, making sure your face stays forward. Whispering sweet nothings about how you should keep your eyes open.

“Shhh, don’t be scared. Tell Eren you want his cock, yeah?”

Eren is a lot more forward. He grabs your wrist and puts your hand on it. He’s close to you, the heat of their bodies combined is making you melt. Eren grabs your chin and Armin peers at him. The brunette grabs your chin and tilts it up slightly. His eyes burn intensely, hard and hot.

“Feel how hard I am? For you and ‘min? Don’t be so nervous. Tell me what I wanna hear.”

“You’re gonna scare them, ‘ren.”

“I’m being encouraging. I wanna hear them say it. What do you want, baby?”

You swallow something in the back of your throat. Your hand squeezes Eren’s cock so slightly, manicured fingers wrapped around the bulge. Eren groans.

“I want your dick. And.. Armins.” Your hips press back and you feel Armin’s cock pressed against your ass. You grind slightly. “I want you both. So bad, please. If you keep messing with me, I’m gonna -”

Before you can finish your sentence, Eren is knocking you back with a forceful kiss. His teeth sink into the plushness of your bottom lip, and Eren is so mean with it. Laughs a little cruelly into your mouth.

“Swear you’re tempting us on purpose. We’ll give you whatever you want, and then Mikasa can take care of you when we send you back to your dorm, yeah?”

“What d’ya wanna do to me?”

That you did on purpose, even Eren knows that. His hands wrap around your throat.

“I wanna feel how tight your cunt is when I force myself in. Damn tease.”

Armin laughs lightly.

“You’re such a brute, ‘ren.”

“It’s not my fault she’s so easy to mess with.”

It makes you obscenely wet. Eren struggling to hold himself back from tearing you right in half. Armin makes up for it but Eren seems like all he wants to do is pound into you. Fuck into your pretty pussy until you cry for him, and bully his way into you with force and impatience. Wants to feel you, tight and whiny. Eren will give it to you. You suspect if you were alone, you’d already been fucked every which way.

But Armin slows the pace. The speed. Armin makes you watch as Eren undresses and Armin plays with your sweet little cunt until you're soaked and Armin wants to see you fall apart. Armin likes when you depend on him, adores your attempts to get him to give into you. Armin wants to take you between his teeth and undo you to tears. Armin wants to make your pussy ache, go almost numb from pleasure, wants to see you cry and cling and need. You feel it within his every move.

Dangerous, so dangerous.

“Armin, what d-do you want?”

“Nothing really.”

“Bullshit.” Eren interjects. Armin doesn’t deny the accusation. You keen, just slightly.

“I want.. I want to make you feel good.”

“Aw, really?”

You nod absently. Eren watches you, and laughs slightly. No one is immune to Armin. His gentle eyes and coaxing, even when you learn of it - it’s hard to avoid. Eren can practically feel how impatient Armin is. They share the same hunger, same urgency. Armin gets his fill like this. The gentle lulling and trust. Of course you want Armin’s seemingly unattainable attention, of course you want to make him feel good. You can know where you’re going and still get lost.

You’re not naive like the rest. Really, you’re just a willing participant.

“How about this then.. I’ll take care of you, and you can take care of Eren?”

Your mind feels absent but you listen. You listen so well, it makes Armin’s cock twitch hard. Armin wants to ruin you more than he wants to breathe air. Wants to suffocate in your pussy and make you cry. God, Armin wants to make you cry.

“O-okay..”

You’re not sure what he means, but Armin is quick to maneuver you. The bed creaks as everyone gets into position. Armin handles you with an unprecedented amount of ease, letting you rest in his lap with your lower back pressed against his thigh. His hard cock is pressed lightly into your side, but Armin is still mostly clothed, and when you look at him - he smiles at you brilliantly. His hands rest on your hips, rubbing little circles into the warm skin.

Eren comes towards you both, still standing on his knees. But his dick is face level with you when you turn your head. You glance at Armin, who squeezes your thigh.

“Eren is big. Careful with your teeth.”

It becomes clear to you quickly what you’re meant to do. It makes your mind feel numb, now only under Armin’s care. You’re overwhelmed, but you close your eyes and take a shaky breath. Armin's other arm is underneath you, securing you. You feel Eren’s hands on your cheek, and before you know it - you’re blinking up at the brunette. Armin’s free hand rests on your middle, just below your tits. He lets you adjust to the situation, your neck craned. Eren’s thumb presses to your lip, and you blink at him doe-eyed.

“Open.”

Eren’s voice is strained no matter how much he attempts to keep his composure. Your face is dolled up in makeup, but your mascara and liner are starting to ring. Eren knows it’ll run if you choke on his cock, and the idea of drool spilling onto your cheeks and down your face. He pulls the briefs on his hips down further. and finally - his cock spills out of it. It almost jumps at you.

It’s heavy and thick and big. It intimidates you, almost knocks into your eye as you free it from the confines of Eren’s jeans. The tip is redder than the rest, and there’s a vein underneath it that pulses. It curves so slightly to the left. You stare at it for a long, long while. How big it is, impossibly heavy and thick. You look up at Eren through your lashes, a bated breath.

“Eren,” you choke, struggle “You’re so fucking big.”

He grins at you.

“Don’t be scared. I just want to use your mouth a little. Just until I can fuck you.”

You nod and close your eyes. Armin watches you in anticipation. Him and Eren glancing briefly at one another as you open your mouth. You stick your tongue out so slightly, almost demure. Your eyes are pressed together too tight. Eren lets his hand rest on the back of your neck, guiding his cock into the heat of your mouth. You make a noise, letting your tongue hang as Eren slides the tip against your mouth.

Your pussy twitches at the shudder he lets out. Deep voice and strong figure shaking as you suck lightly around the tip. Eren’s hand cups your cheeks, brushing his thumb underneath your eye as lick the underneath side of it. You take catalog of him. Eren Yeager, twenty something, student athlete, amateur guitarist and business major. Eren’s quick to praise you, screwing your eyes shut. He’s careful not to hit the back of your throat, not to give too much incase he cums in your mouth before getting a chance to fuck you.

You’re mostly focused on Eren. Or, you’re trying to be. But Armin still has you in his lap. His free hand is ghosting your skin, goosebumps raised. You really aren’t sure what to do. The blonde leans to you, his mouth kissing at your neck and biting your earlobe as he spreads your legs. He plays with your pussy like it’s easy, like it’s nothing. You’re so wet, so turned on from the way Eren softly ruts into your mouth. How Armin touches your body so feather light. His whole palm cups your pussy, and your hips jerk forward for friction he refuses to give you.

Armin leans forward, whispers softly in your ear with a smile like the devil.

“Can you feel how desperate you're getting?”

Your stomach drops, and Armin’s palm presses right into your pelvis with enough force to feel like something. Not enough, never enough. Everything about Armin is gentle, but unwilling. He holds your pleasure and staves if off - makes you yearn for it. You whimper against Eren’s cock and Eren laughs as he fucks a little harder into your mouth.

“Spread your legs a little for me.”

And you do, just for Armin. He rubs your clit again, but this time he sinks a little lower. When Armin finally stops being cruel to you, you can hardly believe how wet a single finger has you. Long, pretty digits so slowly sinking into your warm cunt. You’re so fucking wet, soaking Armin’s middle finger and pooling onto their sheets. He eases his finger into you so agonizingly slow. It’s all you can focus on, a silent plea for more as your hand curls into the sheets underneath you.

“Focus on Eren.” Armin taunts. You blink up at Eren who gives you no sympathy, who smiles as he watches Armins single finger pump into you. His wrist craned, thumb rolling your clit until you’re practically crying out. You rut your hips again, but when you do Armin stops. It’s a silent agreement - his word verse yours.

Armin pumps just one finger in and out of you, sure to touch your g-spot every few seconds without giving you any release. He hums, melodic and so fucking teasing. You feel something ache between your legs, a feeling of neglect.

When Eren pulls out of your mouth, the first thing you do is beg. Frustrated tears starting to make your eyes wet. You manage to blink them back

“‘Armin, please.”

Armin smiles when you turn over to look at him. Your eyes are glassy. Eren can’t help but want to roll his eyes at you, but finds your desperation endearing.

“What’d I tell you about Eren, baby?”

You turn back to the brunette, frowning and frustrated. You feel it in your chest, flustered and upset with your ownnned. Eren can’t help but grin as you wiggle out of Armin’s lap and sit on the bed on your knees. You cross your arms under your chest and huff. It’s so fucking cute. Always so uptight, so on edge - you look so sweet when you beg. Get frustrated with Armin who can’t help but coo internally

“Are you mad, pretty girl?”

You let out an exasperated sigh. Why do you feel like this anyway? You know you’re just worked up, and Armin’s purposeful when he’s on your nerves. You know what he’s trying to do but it’s like you can’t focus on the right things. All you can think about is that heat in your body, and being called pretty girl and about them.

You’re pouting, huffing - generally just being petulant. Eren decides he should give you a helping hand. He sits on the bed so he’s facing you, whispers in your ear to turn around.

And you do, Eren pulling your back to his chest. Without warning, he spreads your legs in front of Armin. The two of them glance at each other, and Eren is quick to take his hands and grip onto your thigh. He rubs your inner thigh, spreading you apart for Armin to see.

“See how mean ‘min is? Won’t even let you cum. What an asshole huh?”

Armin leans back slightly. Take a minute to get undressed as Eren gropes you casually. Squeezing your breasts, traveling until his hands are on your abused cunt. Puffy from want, aching and sticky. Eren is rough, rubs hard but slow circles into your pretty pussy until your back is arching away from him.

“Need help, right? If you want Armin to touch you, you have to really want it. Make sure he knows, maybe beg. You’re smart. Sure you can figure out a good way. I can’t make you cum unless Armin says you can. ‘Cause we’re a team.”

Eren’s teeth sink into your throat, licking the bite-marks with an almost fiendish quality to his voice.

“So.. be a good girl and tell Armin how badly you want him. Use your words. Okay?”

Your entire body trembles as Armin inches close to you. Your voice is in pieces, shot from nerves. You cough lightly.

“C-come closer.. please.”

Eren hums. Kisses your temple with a low voice.

“Good girl. You learn quick.”

You wince slightly, and Armin does. Comes crawling towards you, with just enough inches. You lean on Eren who’s curled around you. He grins slightly, watching the two of you.

“Closer please.”

Armin does. Appeases you and relishes in the nervous-ness on your expression. Armin’s beauty feels like sirens call, when he looks at you - your mind goes staticy. God he’s so pretty. Pink, swollen lips. Smart mouth, nimble fingers. You want him, you want him. Armin gives you a sweet little smile, and Eren shifts behind you. You want them both terribly.

“Hi.”

It’s a whisper, like a secret. You’re still nervous.

“Hi..”

“Tell him, baby. Speak your mind.” Eren encourages.

“Will you kiss me?”

Armin laughs. It’s so light, so ridiculously sweet. You flush.

“Just kiss you?”

“No I want you t-to.. make me cum or whatever.”

They both laugh at that and you shove Eren with your elbow.

“Shut up. You guys are so mean.” You whine.

“You’re just so cute..” Armin says in reply.

“And easy to tease.” Eren adds.

“What else, sweetheart?”

You get a chance to look at him up-close, observe the way his eyes go a little blank with anticipation. Your stomach tightens, clenching your jaw slightly before letting out a shaky sigh. You look away, a deep pressure building in your gut.

“I want you to make me cum. And I wanna feel you.. and Eren inside. I want you both.. want you to c-cum inside.”

When the humiliation from speaking has you in tears, you hear Armin breathe a shaky sigh. Your eyes flutter open, startled - and you look at his expression. His hand around his cock. You see it in his face, seeing all of his delicate touches and waiting. This is the pay off, the way your chest burns from a mix of shame and desire. The tears that make your eyes go wet when you look towards Armin. You find yourself crying before you know what’s happening. Hiccuping a sob, your make-up runs down your cheeks.

And Armin is hard - almost painfully. He almost looks wounded, the way he looks over your expression with lust so thick it’s suffocating. He cups your face in his hands and almost looks proud, looks giddy when you’re whining for him.

It looks like you finally realized - you’re just thinking too much. Armin likes making you feel clueless. It’s all very easy.

“You want me to make you feel better?” Armin hums. You nod. Let his fingers wipe your wet lashes until black gets stuck on the pads of his fingers where he wipes them on the sheets.

“Please..”

Finally, finally - Armin rewards you with his attention. Eren chuckles from behind you, and it reverberates through your chest. Armins fingers cup the back of your neck before pulling you into him. You have it finally, from both of them. Not just Eren, but Armin too - who gives you his undivided attention. You sit pretty against Eren and melt into Armin’s kisses. His mouth is so inviting, spit almost sweet as he licks and sucks on your skin.

All you can feel is relief, your whole body melting. A sweltering heat over-takes you, the kind of anticipation that starts from the top of your skulls and travels through you, down to the points of your toes. Your head feels so fucking heavy, but Eren and Armin take care of you. Eren scoots back so you can lay on him comfortably. The new angle lets you look up at him, and Armin scoots back towards the other end of the bed.

The blonde presses kisses down your body. His lips are plush as the littered opened mouth kisses on your skin. Eren’s hand tilts your neck up to look at him and he cranes his neck down as a reminder of his presence. You kiss him softly and he goes back to playing with your tits. finding rhythm in playing with your hardened nipples. He pinches them lightly making you yelp.

“Wanna see you cum on Armin’s pretty face.” He admits. You shake slightly, whining.

Armin finally makes it between your legs. His body flat against the bed, his hands underneath your knees to fold your knees up slightly. His fingers dig into the fat of your thighs until they’re imprinted. He's gentle with it at first. You can feel everything doubly intense. The warmth of his breath on your cunt makes you tremble - shaking like a leaf in the wind. You can’t control it. Eren soothes you. Whispers sweet nothings into your skin, tells you to be patient. To hold it, just a little longer. Promises that Armin will make you feel so good.

You trust in him and believe. And Armin shoots you a smile from between your legs, and the sight is exceptionally lewd. Everything about Armin is. The slight flush of pink dusts across his nose-bridge and turns the tips of his ears red. Armin wants you - just knowing that sends heat all the way into your gut.

The first lick of Armin’s tongue on your clit sends you fucking reeling. Your entire body goes into shock, almost like you’ve been dropped into cold water. Your clit throbs so hard against the wet muscles, how it slicks over your pretty pussy so eagerly. You fall apart almost instantly. Mouth gone cotton dry, your hands tremble as the snake through Armin’s blonde locks. He lets his tongue lap up your clit in long, hard strokes. Drags the tip through your folds and collects all of your arousal, covering himself in it. The sight is pornographically intense. The feeling is absolute fucking euphoria, an unimaginable amount of reprieve. The pleasure is heavy hitting. The slow, syrupy drag of Armins tongue on your clit that’s been teased to the point of numbness. Your whole body goes boneless as Armin explores - a silent scream leaving your lips as he snakes his tongue all the way around your clit with a pleased and muffled moan.

You’re choking something out incoherently. A slight vein in your neck, a tremble in your hands. You can’t breathe. It’s Armin and Armin is so good with his mouth. So good at what he’s doing, you feel like you’re only seconds away from cumming. The pressure is even and steady, constant as he holds your hips down and sucks. Sucks your clit into his mouth, lets it rub against the softness of his mouth. He sucks your clit like an apology and prayer all in one. You short-circuit, nails scraping Armin’s scalp with intensive need. Your mouth drops open.

“O-oh, fuck - Armin. Fuck.”

“Feels fucking good, doesn’t it baby?” Eren says, chest swelled with pride.

You nod lightly as he watches. Seeing Armin give you head is making his dick twitch against his stomach. Your thighs are tense, overwhelmed. Armin lets you crush his skill between his thighs, just slightly - willing but not moved. Intent on making you cum, you thrash but Armin is insistent. Armin stays still, works your cunt like doing this pays his bills. Stubborn and patient, much like you’d expect.

“Cum on his pretty fucking face, yeah? Give him what he wants, cum for him.”

Eren eggs you on and you lose your steadiness. Whatever thing you’d been holding onto is lost on you. Before you can let out any form of verbal warning - your fingers are tightening in Armin’s hair. Your voice is silent before you practically scream, mouth dropped open. The tension snaps like a rubber-band, and your orgasm crashes into you like a semi. The first one, the most pro-longed one of the night - but nowhere close to the last. You cum and you cum and Armin doesn’t stop. He doesn’t let up at all, works you through your orgasm until you're practically begging him for mercy. It feels so fucking good.

He stops, finally, only to take an inhale of air. His chin is covered in your cum. You stare at him, dazed.

“I hope you don’t think we’re finished with you.”

“You two are out to kill me.” You say finally. Eren laughs at this.

“Hell of a way to die, huh?”

You laugh raggedly at that. Eren rubs your thigh with adoration as Armin comes up from between your legs. The only thing he does is kiss Eren, and Eren welcomes it. You feel your heart patter with adoration in the familiarity of the gesture, they’ve done this before. You rub your thighs together, watching with a sigh.

“You taste sweet, baby.”

“Let Mikasa have some when you get back, okay?”

You fluster at the thought of it, of Mikasa going home and taking care of you. Your heart-beat is loud as Eren looks up at you. He helps you sit back up, and you wipe your eyes with the back of your hand. You’re still wanting more but the emotional impact alone has you yawning and reaching.

“Armin had his fun so you gotta let me have mine, sound right?”

You gigg lightly as Eren turns you around. Eren is strong - you can feel it in the way he maneuvers you into his lap. Armin is behind you, feeling around the bed to find a pillow to place under your back. Without ever speaking a word he seems to know Eren’s agenda. Eren leans forward as Armin places a pillow underneath your spine. Your legs go over Eren’s thighs as you hit the plush bed sheets. Eren sits between your legs, hard cock heavy and hanging. His hand, slowly traveling up to your lower stomach. Eren presses on it lightly, just enough to make you squirm.

Behind you, you hear Armin finally take his pants off. He’s on his knees next to you, and you stare at his cock when it comes out of his briefs. It’s pretty, curves up and is pink at the tip. It’s long - a size you’d want to take over and over it. You blink up at Armin who takes your hand and wraps it around the base, a soft shuddering ripping through his body. You stare at him. His moans sound fucking angelic - soft and unyielding.

“I can use my mouth, ‘min.” You offer. He shakes his head a little.

“I’m sensitive, pretty. I’ll cum in your mouth and I don’t want that.”

He smooths his hand on your forehead. You spit into your palm and go back to stroking it, watching his expression. His face twisted beautifully, one of these days you want to tease him back. Ruin him, he’s so pretty.

“I wanna cum inside of you after Eren does. That’s our favorite thing to do, and it’ll make you happy - won’t it? So just keep s-stroking me like that.” He says. His voice comes out in a hiss, his entire body twitching with the urge. Armin would be lying if he said he didn’t wanna cum on your face the way you look now. But his desire to make you happy and mark you with Eren, the three of you, outweighs his others. Plus, your manicured little hands feel so fucking good around his cock, they’re so soft and so careful. You nod before Eren smacks your thigh lightly for your attention.

“Gonna get you ready f’r me but I expect you to cum before then, yeah?”

Eren’s green eyes are focused down at you. You realize something when you look at him, that Eren’s light involvement must serve its own purpose. Eren has always stood out but when it came to you and to them - he was always on the sidelines. You feel something stir in your belly when he looks. Everything about Eren is exceedingly intense. His presence when he lets himself be there - it’s absolutely fucking intoxicating. Unlike Armin who plays off of you, Eren is almost a force of his own. Unstoppable in its magnitude, how easily it overpowers you.

You breath catches but Eren continues to slide his fingers over your waist. He’s handsome, tan skin and broad frame. Even like this, he casts a shadow over your whole figure. Your smile warbles as you look at him, blinking when Armin’s cock twitches in your hands.

“You’re so fucking sexy.”

“You too.” You say. Eren laughs as his hand rests between your legs. The cool metal of his rings press against your thigh. You hear him swear under his breath.

“Fuck.. gotta take these off.”

You shake your head, tugging you lower lip between your teeth.

“Is it weird if I ask you to keep ‘em on? Like if you think it’s.. safe I don’t mind ”

Eren looks at you, shock evident on his face. Armin laughs lightly at you.

“Kinky little shit.” Eren teases.

You frown at him, scrunching your nose. He leans forward and presses a kiss to the inner corner of your mouth. Eren is so consuming, it startles you. Your lungs feel like they’re running out of air when you feel his thick, callous fingers rubbing against your cunt. You let out a soft whine as he rubs your pussy - getting a feel for it. You’re so soft against his hands. Soft and warm and so slick. Eren knows it’s killing you - but he’s slow with it in his own way. Like he knows it’ll overwhelm you. Your hips jerk forward when you feel the tip of his middle finger, the pad of it poking at your entrance.

You flutter against nothing as Eren teases it.

“Fuck, you’re so wet.”

You shiver slightly. Armin’s hand comes around to rest on the base of your throat and you look up at him with beaming eyes. He smiles down at you.

Eren grants you a mild mercy when he presses his fingers into you. You’re perfect and willing - your cunt sucking in his middle finger tight. He hisses as you whimper, voice going coarse at the sudden intrusion. It feels good when he does it - his fingers are so thick and so long. reaching so deep inside of you without much effort at all. Eren lets you adjust, his other free hand resting on your lower stomach and pressing lightly. He pats your skin, laughing at the way your expression goes hazy.

“Easy, easy.” He hums noncommittally. He knows you want more and he’s set on giving it to you. But Eren isn’t small - he still has to prepare both Mikasa and Armin to take him everytime. He knows you’ll be no different, and he knows he doesn’t have it in him to let you adjust when he does fuck you. It’ll have to be hard, and deep.

When your breathing stops being so labored, Eren lets his ring finger stretch you out. The same as before, the same amount of patience as you take him. Armin’s cock has a hard twitch every time you struggle - the soft burn in your calves and belly as Eren splits you open on his fingers. He waits again, easy and patient, until you seem ready. Reads your body for any signs of discomfort before you feel him, pushing till he’s knuckles deep. The pads of his fingers find your g-spot with no trouble and your throat feels constricted. Your free hand grips the sheets, toes curling. You take in a shaky inhale.

“Oh, f-fuck, ‘ren.” You curse. Eren grins, voracious. He presses hard against your g-spot, stretching his fingers out to make sure you’re comfortable. He holds the position inside of you. Only when the tension gives does he move. Takes a minute to get another one in, a third -just to be safe, but it goes in so quickly. Before you understand what’s happening, Eren’s making you feel strange. Three thick fingers pumping in and out of your cunt, and curled at the perfect little angle.

You feel it before you can understand what’s happening. Something hot and uncontrollable - definitely too much for you to deal with you. Your mouth drops open, the sensation heightened as Eren’s hand presses down on the space beneath your tummy. Armin looks down at you, and you look at him. You’re almost frightened.l

“Breathe, slow - just like that. I know, it’s so much for you, huh? But it’ll feel so good.”

You try and listen, and Eren’s zoned out. Eyes focused on your sweet little pussy, fucking into it with his fingers. The constant and steady motion triggers something deep inside of you. It happens before you can process. You let out one wounded whimper before breaking out into a full cry. Warm, clear liquid sprays at Eren.

He lets out a deep groan as you cum and squirt all over him. How you’re so tight around him as you let out a cry. The orgasm is nothing short of intense, too much. You can’t think of anything at all, just Armin who holds you down and Eren who fucks you through it.

“Fuck, fuck!”

Your high drops off in short bursts, tremors running through you as you open your eyes to find Eren who looks like he just won the lottery. You give him a shaky smile. Armin redirects your hand to his stiff cock and gives you a little grin.

“You think she’s ready for me, ‘min?”

Armin laughs good-naturedly.

“I think if you hold off on her any longer, she’ll kill us both.” Armin says with mild amusement. You muster up whatever remaining strength you have to sit up and sigh.

“Damn right..” You trail off, propping yourself up slightly.

“Are you sure you don’t wanna use my mouth, Armin?” You offer. Armin chuckles slightly.

“I don’t wanna cum before Eren does.”

“Competitive dick.” Eren spits. Armin sticks his tongue out at him but doesn’t suppress his giggle. You shake your head.

“I can go slow.”

“It’s not the speed, baby. It’s you.”

You look at Eren who looks a little smug before looking back at Armin who has pink dusted over his cheekbones. You flush slightly, covering your face with your hands as Eren laughs at the both of you.

“We’re having a fucking threesome and you’re embarassed cause Armin’s attracted to you? Seriously? I expect it from Armin, but c’mon.”

“I’m embarrassed by you, too.” You correct.

Eren’s eyes widen and before you know it, he flushes too. You and Armin break out into fits as he covers his face with his arm, looking away.

“Fuck that’s kinda cute.”

“No shit.” Armin jabs. Eren glares at him with no real malice before his hands come up behind your knees.

“Stop being cute so I can fuck you.” Eren says, insists. You giggle lightly.

“You don’t think I’m cute when I cum?”

Eren leans forward, tossing the pillow that was underneath you to be on the floor so he can lean over you. His teeth nip the skin on your jaw, tracing down to your collarbone.

“Think you’d look the fucking cutest with my dick inside you.” Eren says with evident sarcasm.

You laugh a little at that, before looking back at Armin.

“I want you to feel good, too.” You pout. Armin laughs at you and Eren scoffs.

“Armin’s a pervert who likes watching. He makes me and Mikasa fuck each other so he can watch.” Eren informs you. You think of the events of the entire night before your mouth drops open in a shocked gasp. Armin shrugs at you, innocent smile.

“Even when you can join?”

“Yeah, pretty girl. Even then.”

“Told you he was a pervert.” Eren gripes. You laugh at that.

“I wanna watch you get off.” You reply easily. Armin and Eren both glance at each other, as Armin shakes slightly at the suggestion, eyes wide. Eren shakes his head.

“You might’ve broken him.”

“I’m being serious!”

“We know. That’s the problem. Whatever you want though, baby. Come here, and Armin - sit over there.”

Eren is quick to handle you. He flips you over, pressing your spine until you’re laying on your stomach. He spreads your thighs like that, and you lay between Armin’s legs. You’re up-close, Armin stroking his cock perfectly in your view. It’s almost too teasing, cruel for him to be touching himself but it’s better than not being able to see him. You feel Eren behind you. His whole body folded over you. His hands bringing your hips up, the heaviness of his cock pressed against your pussy. He groans, shuddering.

“Don’t know how long I’ve been wanting to fuck you just like this.”

Your toes curl slightly, hands reaching back to hold your calves as most of your body remains pressed into the mattress. Eren goes forward. His cock is big, thick as it ruts against your pussy. It’s so heavy. You wiggle your hips back as your cheek is pressed against the sheets, eyes fluttered as Armin gets off in front of you.

“Fuck me, ‘ren. Please.”

Eren’s fingers dig into the meat of your thighs and he nods.

“Uh-huh, take a deep breath for me.”

And you do, one deep inhale as you feel the tip of Eren’s cock push through the sweet folds of your cunt. You shiver as he moves, slowly breaching until your body gives out into the bed. Your eyes roll promptly into the back of your head, the intrusion of Eren’s cock making you moan so loud it reverberates. Your entire body feels like it’s shutting down. It’s so fucking big. Thick, even just at the tip where Eren has barely fucked into you. Your hands clench the sheets as Eren curses under his breath.

“Oh, f-fuck, baby - your pussy is perfect, fuck. Fuck, yeah - shit.”

Eren’s expression is concentrated as your walls clamp down on him. So hot it almost burns, tight and wet and perfect. You soak Eren, sucking him in tight. His nails leave indents on your thighs as he eases the pace. His head dropping slightly, hairs falling into his face.

“Eren, you’re so big.”

“Yeah? Can you take all of it, d’ya think?”

You nod rapidly as Eren’s hands come down on your ass. He’s mesmerized by the way your body looks, watching how he disappears into you. How welcoming you look, with your knees propping your ass up so nice. You look so fucking good.

Eren’s slow fucking into you, pushing further and further - each inch making your tongue feel heavy in your mouth. You feel drool pooling onto the sheets in front of you. The stimulation leaves you weak, almost boneless as you let Eren inside. Your body is begging for it, to be full - to feel Eren’s cock all the way in your lungs. He’s big enough to do it, big enough to make you cum just like this. What felt like an impossible task, cumming again, suddenly ends up being close into your reach. You’re losing your cool.

Through your haze, you look up at Armin. Armin is watching - his fist around the base of his shaft and his eyes heavy. He looks like he’s just barely keeping it together, and even through your aimless pleasure, you feel another pulse of heat run through you as he gets off.

“D’you like seein’ him fuck me Armin?”

“Fuuck, yeah. Yeah, just take it, okay?”

You nod obediently, fucking yourself sligtly back into Eren to encourage him to take what he wants. He puffs out a wounded sound.

“Shit, it’s in. Fuck, look at you.”

You smile deliriously, cunt twitching as Eren’s cock reaches the deepest parts of you. It drags on your walls so slow it’s almost painful. Before you can relish, Eren is pulling out. You almost whine, but the sound gets cut off as Eren pushes all the way back in. You cry out.

“Aaah, shit!”

Eren secures himself, his position behind you by grabbing you tight to him. He sets a pace easily - and then it starts. Eren’s pace is ridiculous - deep and careful but consistent. He pistons into you with a feral urgency, cock knocking against you with each thrust. The bed underneath you starts to creak, headboard slamming against the wall with each of Eren’s motions

He fucks into you over and over, groaning harshly and spewing praises. You can’t focus on anything but being fucked, but taking it. Even with all the prep, after cumming twice - Eren fucking into you leaves you in a state of imbalance. It throws you off, how good it is, and how naturally he works your cunt right open. You can feel that familiar tug, the tension of an orgasm as he pounds into you for all your worth. He gives it to you like you begged for it. Fucks you open on his cock with somehting that borders brutal.

He’s trying not to lose his fucking mind, trying to make sure he’s consistent enough to make you feel good but you make it hard. It’s hard to be careful when your voice is practically begging for him to cum inside of you. Hard to be a good and unselfish partner when he’s thinking more with his dick than he is with his hand.

He doesn’t want to stop, he can’t - but every time you take all of him like the good girl you are, he has half a mind to relish in it. Your pussy enveloping him, all of him, clamping on him like you’re trying to empty him of everything he has. He’s more than willing to give it to you, and every time your hands reach back to feel for him and steady yourself, he loses it a little more.

Eventually, he grabs your hands and secures them behind your back. Moves your neck so you’re looking at Armin, and leans over you. His voice is in your ear. Somehow he’s deeper, and his balls slapping lightly against your clit. You shiver as you feel Eren’s breath against your ear. The gravel as his voice as he starts to come apart.

“You’re s-squeezing me so tight, fuck. Fuck, baby - look what you’re doing to us. Shit, shit, shit.”

You feel it, again - this time the waves are much longer. It’s different, almost like it’s taking your body effort but you feel it. When Eren shortens his thrusts into being a slow grind. Eren knows your body too, can tell what you need.

“Cum for me, baby. Need it, cum for us, please -”

You’re pushed over the edge blindly. Your entire body stops before convulse. You cum hard - a blinding white in your vision. You cum and you cum so hard, you choke on air. You’re breathless from it. Breathless and boneless, just laying and feeling the euphoric aftershocks.

Eren chokes out a half-stuttered warning about cumming inside of you. Thick coats of white shoot into you as Eren limply fucks into you and rides the rest of his orgasm out. Sweat is all over your skin in a thin sheen, the intensity leaving your entire body aching.

It’s silent for a good moment before you regain strength. Eren pulls out of you and sits back, and you just barely manage to get on your elbows. You drop your head and laugh a little.

“Holy fuck.”

Eren nods in agreement, and Armin lets out the breath he was holding. You take a few seconds to collect yourself before you and Eren look briefly at each other and zero in on Armin. He looks between the two of you and swallows slightly.

“Can the two of you not look like you’re going to eat me alive?”

“Now you know how it feels.” You tease. Armin stares at you before laughing lightly.

Eren adjusts so he’s behind Armin. Pulling his back to Eren’s chest, Eren presses light kisses to the column of Armin’s throat. You crawl towards Armin, seating yourself in his lap so you’re facing him. He looks at you with wide eyes as you adjust to be over his cock, and you take your hand to press his cock against your folds.

“You’ve done enough today, let me do this, please?”

Armin nods, mesmerized by the way you move. By the smudged makeup you still look pretty in, and the sweat that beads and falls between your tits. The way your entire body moves against his. Eren chuckles behind him, hand around Armin’s waist.

“You fold so fast.” He muses. Armin huffs.

“Wouldn’t you?”

“Fair point.”

You’re silent, lips pressed together as you adjust over Armin’s lap. You line his cock up with you, and Eren’s cum drips down onto his shaft. It’s lewd but oddly makes you happy. Armin throws his head back onto Eren’s shoulder as he feels you sink down on it easily, needing no prep at all. Your hands steady themselves on Armin’s shoulder as you lean forward to kiss him.

“You feel so g-good.” Armin chokes out. Even fucked out of your mind, Armin’s length feels nice. It’s almost comforting, the way he’s so snug. You lift your hips up and drop them back down again, setting a quick pace when you ride him. The sound is filthy, Eren and yours cum coating Armin’s cock, your tits squished against his chest. But Armin looks blissed out, mouth in a soft pant as his hands secure themselves on your thighs. He moans lightly into your mouth.

“Want your cum inside me, ‘min. Please? Can you cum for me?”

“You hear that, baby? She wants you to cum inside. You’ll be nice and give it to her, yeah?”

Armin groans, huffing. He shakes his head.

“You two are evil.”

“Right back at you.”

Armin holds your hips down when he cums into you. It’s loud when he does, and it goes on forever and ever. Even longer than Eren’s did, you take the opportunity to pepper his face in kisses while he finishes inside of you. His whole body shakes as he spills into you, making your pussy more sloppy as he fucks in and out of you shallowly by thrusting his hips. When he’s finished, you’re giving him another sweet little kiss, pressing your cheek against his shoulder and peeking at Eren.

“I need to sleep for a million years.”

“Bath first.”

You and Eren collectively groan.

__

You don’t remember much about the next morning other than falling asleep the night before after your bath.

But, you wake to the sun pouring through the blinds. A body next to you, but not the ones you expect. Mikasa is peering at you while you sleep, and you’re not startled by her presence. You yawn slightly, the aftermath of last night exhausting you. It surprises you but not enough to fuss over it, it seems like something those scheming bastards would do.

“G’morning, Mikasa.”

“Morning.”

She has a pink flush on her cheeks. It makes you chuckle, slightly.

“So..that’s why you wanted me to like them? It worked but -”

She flushes, scrunching her nose before scooting in next to you. Her face is so close to you, it makes your heart pound. Her hand cups your face, and you’re used to her affections, but this is still much more than you can expect. You put your hand over hers.

“I like you.”

“I like you too.”

She bites her lip lightly.

“And them?”

You laugh aloud, reaching forward to brush your nose against hers. You hum.

“They’re growing on me.” You offer. She laughs at that, and her smile is warm and bright. You think looking at her you understand it. If Armin is the ocean, then Mikasa is the Earth, and Eren is the sky. You can’t help but wonder where you fit into it, into a set of three.

But you figure, if they’ve tried so hard to welcome you, that you embrace it. You think that even Devils of Temptation have hearts to offer.

And the sex is nice. And Mikasa is pretty, and drowning in so much pleasure really isn’t like drowning at all. Really getting this far feels like floating endlessly. When the water carries you, you let it. You close your eyes and succumb, and let yourself hold Mikasa when you kiss her. She kisses you deeply, and there's a need attached to it. She pulls away before it gets out of hand, wiping the spit off her mouth before kissing her cheeks.

“As long as you don’t hate them.” she finishes. You laugh.

Before you can say anything, you hear a noise at the door that sounds an awful lot like Armin and Eren bickering over keeping quiet. You stare at it, shaking your head with a smile before looking back at Mikasa with warmth in your eyes.

“Not even close.”
