Humming softly, Armin sprays the top of his desk with the special cleaner he’d borrowed from his stepsister, who worked for the Ackerman Teahouse in the inner ring of Paradis Isle. She’d been working for the owner, Levi Ackerman, since she was fifteen, and eight years later, both her relationship and her job were long running and going strong, with her only being a notch below the owner when it came to workplace superiority. Her boyfriend, Eren, who she lived with ( he was also two notches below her in superiority in the teahouse: one spot beneath the longtime waiter, Oruo Bozado, and two beneath the assistant manager, Eld Jinn ), drove her to and from work every day. 

They’d met years ago in preschool, years before Armin’s mother married Y/N’s father when they were in middle school ( Armin in fourth grade and Y/N and Eren in sixth ), and had been best friends for years until Eren’s little schoolhouse rival Jean Kirstein tried asking her out when they were all fourteen or so. Eren had seen red and interfered, saying that they were already dating and whisking Y/N away. Y/N had teased him about it relentlessly, of course, and he’d asked her out for real that same day in his house’s kitchen. She’d said yes, then went home and told Armin everything — Eren shaking his head and hands the whole time, his face pinker than the strawberry milkshake he’d bought her on the way to her house. Now, Armin had had his fiar share of crushes on girls and boys at school, but he had made extra sure to never let it slip that he’d had a crush on Eren ever since Y/N had introduced them to one another ( which meant he’d liked Eren for almost three years at that point ). He just wanted to be happy for his stepsister, even though seeing Eren and her kissing and holding hands all the time sometimes did make his heart hurt. 

Now they were all in their twenties with jobs as well as their own places ( Eren and Y/N living together in a small but cozy house in the outer ring at the outside edge of the middle ring that they were renting from a friend of Eren’s father, and Armin in a tiny, tiny apartment in the middle ring as close to both Paradis University and his work as possible ), and Y/N was still dating Eren. They were both still working at the teahouse with Mr. Ackerman when they weren’t working during their fourth year of college. Eren intended on being a doctor like his father, and Y/N was studying to get a Masters in History, not really wanting to be much of anything — and Armin knew why. She’d made him promise not to tell Eren at the time, but one of the military’s commanders had scouted her in her first year of college and she planned on joining up after her twenty fourth birthday. Eren had known for a couple years now, though — when he’d found out about seven months afterwards it had caused a huge argument that ended with Y/N leaving their ( then ) apartment to stay at Armin’s and Eren to freak out once he woke up ( as he’d stormed into their bedroom and slammed the door before going to bed angry ) and realized she’d left. They’d made up then, and that had been the end of it as far as Armin knew. 

And despite all of those ups and downs, Armin still had a huge crush on Eren as much as he didn’t want to admit it. It was one of the reasons why he’d argued so much against them coming over today. He didn’t want to mess up the eight year relationship that his stepsister and friend had just because of a silly crush that he shouldn’t even have. 

As he backs away from the entertainment center after cleaning it, his hip bumps the coffee table and a pen he’d left on it alongside his homework rolls off and under the couch. Cursing under his breath, he carefully moves the coffee table and gets on his hands and knees before blindly reaching for it under the couch, fingers grasping at nothing but the empty air before he finally manages to grab it — but not before his fingers brush the edge of something that spikes his curiosity. Sitting back on his calves and putting the slightly dusty pen on the table, he quickly gets back on his hands and knees with his face pressed to the floor to look under the couch, and his eyes widen. The book he’d been looking for for three whole weeks had been under the couch the entire time!

He tries his hardest to reach for it again, and the tip of his middle finger does brush against it — but he only manages to push it further away and completely out of reach, almost to the back of the couch entirely; he couldn’t move the couch either, it was too heavy. “Are you serious?” he groans, rolling his eyes and throwing his head back slightly before looking at the little loop underneath one of the cushions with a twinkle in his eyes. The little couch, gifted to him by Eren and Y/N as a housewarming gift, pulled out — and when you started to open it, the area beneath the couch was completely revealed. He could just open the pullout, grab the book, and be done with it!

Doing just that, Armin carefully pushes the pullout up, holding it up with one hand while reaching for the book with his other. It is, yet again, just out of reach, and he inches closer and closer to no avail. Hesitantly letting go of the opened pullout, he smiles softly when it stays propped up without him having to hold it up and simply bends over the front of the couch, one hand braced on the floor inside the couch’s opening and the other once again reaching for the book, the side of the couch slightly digging into his stomach as he stood on his hands and knees while practically draped over it. 

Right as his fingers close around the corner of his lost book, Armin hears a loud, creaking crash, and the lifted rectangle of the pullout couch falls back on him — it doesn’t hurt ( okay, maybe it did, and maybe the pain from it made him cry a little ), but when he tries to get out he finds that he’s completely stuck and unable to move. He pushes back and struggles to escape, trying to ignore the pulsing pain in his back, but the weight of an entire bed being on him coupled with metal that scratches at his skin painfully when he tries to back out makes him stop. What was he supposed to do now? He couldn’t get out of this, and he lived alone. On top of that, he had hardwood floors and his knees were starting to hurt. 

A loud thud outside reaches his ears, and his eyes widen; Eren and Y/N must be here, they could help!

“Y-Y/N! Eren! Help, I’m in here — I’m stuck!” he shouts, knowing that his voice is muffled through the couch but not caring. He’d be let out soon, so what did it matter? 

The door opens and closes behind him, and he repeats himself — but he doesn’t get a response. “Eren? Y/N? Hello?” Two big hands cover each of his asscheeks, making Armin’s eyes widen in surprise. Pushing him out wouldn’t work, what were they thinking?! “H-Hey, what are you — WHOA, WAIT-!”

His shriek was triggered by the two hands taking both his pants and his underwear by the waistline and yanking them down to pool around his knees, baring his ass to the faceless person who had come in through his front door. They part his cheeks, and he wiggles against their grip as best he can. “D-don’t — Don’t look there!” he whimpers, wondering why at first his stepsister’s boyfriend ( who had never looked his way like that a day in his life ) was doing this until he remembered that his stepfather had told him over Christmas last year that Eren had asked permission to ask Y/N to marry him, so it just couldn’t be him — but if it wasn’t Eren ( and couldn’t possibly be Y/N, with how big this unknown person’s hands were! ), who was it?

Armin pales from his place stuck in the couch. He’d — He’d unlocked the door for when his stepsister and her boyfriend came over. He always did, even though Y/N had a key, and he’d been screaming for help… Someone on the street had heard and decided to help themselves. He’d gotten himself into this predicament all on his own. 

A hot, wet length of flesh swipes over his twitching, exposed hole, and Armin tries to move away. It takes him a moment to realize that it’s the person’s tongue, and his eyes widen almost comically all over again. “N-No, don’t put your t-tongue there, it’s dirty!”

The person behind him ignores him, instead slurping loud and messily at the hole beneath it, tracing it and drawing various shapes along the sensitive flesh, ignoring the whining man beneath him’s struggles. Armin’s eyes cross when the strange tongue, which has coated his whole whole in a heavy layer of spit, is joined by a long, thick finger, which doesn't hesitate to curl up in him and begin swirling around his insides, almost as if it were searching for something—

Armin lets out a shriek as the intruding finger brushes across something that sends sharp stings of pleasure up his spine, his hole clenching around the finger in his ass and the person’s mouth leaving his ass to nip, bite, and suck across his exposed lower back. The finger brushes across it again and he keens, whimpering as the finger is slowly drawn out, then whimpering again when he feels the tip of a second finger press against his hole along the first as well as a hot, sticky liquid he just knew was spit dribbling over them. Before he knew it, the two long fingers are pressing inside him again, crooking up and stretching his insides as they search again for that little button hidden inside. “O-Oh fu-uck-!” Armin moans, letting his head fall forward, “Fuck — Please, please — C-CUMMIN’!” he wails, arching his back and forcing his ass back into the pleasing touch as best he can as he costs the floor in his thick load. As he came down, he was barely holding himself up on shaky forearms as the inner skin of the two fingers beside the two in his ass press against the heated skin of his asscheeks, and he whimpers when he realizes just how long these fingers were when he feels them pressing so deep in his guts and scissoring open to stretch him more. 

Armin’s cock slowly begins to harden again and his sensitive tip rubs against the rough cloth of the couch, assisting the stranger in making his entire body tremble. The fingers inside him twist and turn and stretch and toy with that special spot in a way that has Armin, regardless of previous inhibitions, pressing back into the expert touch as best he could and whining shrilly when the fingers he’d only just gotten used to are pulled away from him and he’s left empty. 

A moment passes, Armin’s thighs shaking from the feelings coursing through his veins, and suddenly the pullout that had had him trapped is lifted, freeing him. Refusing to look a gift horse in the mouth, he quickly clambers away from where he was stuck, backing into a strong chest and watching as tanned forearms close the couch and lazily toss the cushions back. The familiar glint of a series of thick black rings on the tanned hands and a prominent black skull ring on the middle finger of the man’s dry hand catches Armin’s eye and he pales again despite his aching length pressing against his stomach, slowly looking up to see just who was behind him even though deep down he knew. 

As he’d feared, it was Eren. 

Green eyes lock with his own blue ones, and a dirty grin is on the handsome older man’s face as Armin thinks back over what had just happened. The entire time that he’d been feeling so good with a ‘stranger’s’ fingers up his ass, it was Eren — Eren had done  all the sinful things that had made his body feel good, Eren’s tongue and teeth had drawn patterns of saliva and bite marks across his skin, his lips had sucked love bites across Armin’s lower back and ass — Eren, the boy he’d had a crush on since he was eleven. 

Eren, his stepsister’s boyfriend. Soon to be fiancé.

Shaky breathing from across the room catches Armin’s attention, and the moment he lays his eyes on the cause he freezes. Y/N is standing there, wide eyed and slightly red faced, her mouth slightly open in surprise. Armin can feel tears welling up in his eyes, and as soon as his lock with Y/N’s he bursts into tears. Eren had cheated on her, and with him. This was his fault, he’d ruined their relationship, it was all his fault. Armin tries to wipe all the tears away with the backs of his hands, which are curled into loose fists, but they just keep coming. 

“I’m-m s-s-sorry!” he sobs, feeling so overwhelmingly guilty that he just couldn’t think of anything else to say. “I-It’s just — The couch fell ‘nd I couldn’t get out — I was stuck, I swear! He just came in ‘nd this happened, but I p-promise I d-didn’ kn-know it was him, Y/N, ‘m sorry!” He keeps crying, not even making an attempt to stop the tears. He deserved to feel this way, he knew it — and so did his conscience. 

That’s not an excuse, his mind hisses cruelly, This is your fault and you know it; you’ve liked him for years, and now that she knows, she’s going to hate you. She’s never going to want to see you again, and you deserve it. 

No! He didn’t want her to hate him, he loved his stepsister ( perhaps a little too much, if he were honest with himself, but unlike his inner admittance of liking Eren, that he refused to acknowledge ). He’d just — he’d have to make it up to her. He could do that, right? Surely there was something he could do to earn her forgiveness?

“Hmmm, I guess there is something you could do,” she replies, making him realize that he’d been rambling out loud. 

“What?! I’ll do anything!” he cries, tears still falling even as he wipes them from his cheeks. Y/N glances to Eren, who is rubbing little circles on Armin’s bare hip with his lust-darkened eyes locked on hers already. 

She asks quietly, her own eyes darkening, “Anything?”, and Armin nods his head affirmatively furiously. Apparently he hadn’t noticed that his underwear and pants were still pooled around his knees and therefore he was completely bare in the most sensitive area before her, and she sure wasn’t about to remind him. She was enjoying being able to look down on his little pink cock, still hard and aching despite Eren getting him off earlier when he was still pinned. 

Y/N had known, of course, that her boyfriend had a thing for her little stepbrother — he didn’t love him like he loved her, of course, but she knew ( he’d told her, even, going into great detail about how much he wanted to see the younger man’s face while he fucked his ass and the blodn’s face was inbetween her tits ) how much he lusted over the no doubt tight hole the short blond kept hidden away, and Y/N hadn’t minded; after all, Eren had been jealous when she admitted she was attracted to his friend Jean, but he’d still said he didn’t mind if she fucked him and even after she did, later the three had all fucked each other, so it was only fair that she grant him this at least once — and since she’d known for years that Armin had been in love with her bothfriend, she knew he wouldn’t say anything — so their parents never had to know. 

Eren’s obsession with the thought of Y/N’s sweet little stepbrother sandwiched between the two of them began when the two of them had first heard him calling Y/N’s name while Eren fucked her senseless one night Armin had stayed over at their place, and the thought of him splayed out beneath all four of their wandering hands, his and hers, hadn’t left his mind since. 

“Please, what can I do to make it up to you?” Armin hiccups, more and more tears welling up in his eyes as the silence stretches on. 

Y/N’s eyes, darkened with a lust of her own, glint wickedly, and she grins as she spreads her legs a little and says, “Come lick my pussy.”

Armin’s eyes are wide. Surely she’d misspoke — surely she couldn’t have just asked him to do that! They were family, for Ymir’s sake!

You’re step-siblings though, a toxic part of his mind trilled happily. You two aren’t related, so it isn’t really bad, just a little… taboo.  

She shrugs when he stays quiet, turning away from him and crossing her arms. “Well, I suppose I could just… I don’t know, break up with Eren and cht you out of my life for betraying me instead,” she says cruelly, and as she expected, Armin panics. 

“N-No! No, don’t! I’ll do it, I promise I will! It’s j-just…” he trails off quietly, looking down

Y/N raises an eyebrow. “‘It’s just…’ what? What’s the issue?”

Armin squirms uncomfortably, Eren still warm against his back, but despite the discomfort he answers. “I’ve — I’ve never done… that.”

Y/N snorts in amusement, “What, you’ve never eaten pussy?” Her tone is mocking, teasing even. Armin whimpers quietly at her words, but refuses to answer this time — but Eren understands exactly what he’d meant. 

“Baby… I think your baby brother is still a virgin,” Eren purrs lowly, squeezing Armin’s hip a little and making him jump. Armin had almost forgotten Eren was still there, as crazy as it seemed. His cheeks are bright red, and fresh tears of embarrassment well up along his waterline. Y/N looks to him for confirmation and he nods tearfully, his bottom lip trembling as he holds back the tears, and she grins in an almost predatory way as her pupils blow. 

“C’mere, Armin,” she murmurs, and he pulls away from Eren and crawls over to her, not realizing how easily he was playing directly into his stepsister’s and her boyfriend’s darkest desires. Kneeling at her feet, he watches in rapt attention as she lifts a leg and places her foot on the next to bottom shelf of one of his bookshelves, revealing her panties beneath her skirt to him. His already hard cock twitches, and he continues watching as she hooks a finger around one hem of her panties and pulls them to the side, revealing her glistening pussy to him and making him swallow hard, his mouth falling open after. He’d never seen one outside of porn after all, but when she hums at him and rolls her hips up into his slack-jawed mouth, shocking him as her wetness slides over his chin and lips, his tongue flicking out to collect the slick instinctively. A string of slick connects his chin to her cunt for a second before snapping and Armin’s tongue darts out to lick at where it was sticking to his face before one of Eren’s big hands press against the back of his head and force his face against her sopping cunt, his eyes rolling back as he runs his tongue up from her hole to circle around her clit. Eren rubs his face against her pussy a few times before pulling his hand back, pleased to see Armin following the way he’d led him even without him pushing him into it anymore. 

Armin looks up curiously as she lets out soft whimpers, his face still in her pussy as  one of her hands pressing against the back of his head. His little nose presses ever so perfectly against her swollen clit, and his whole face is revealed to be soaked in her juices when he pulls back a little. “L-Like that?” he whispers quietly against her soft heat, and she shivers some then laughs a little at the feeling of his warm breath against her cunt. 

“Yeah baby, do it just like that…” Y/N whispers, taking her bottom lip between her teeth and fisting her hand in his blonde hair and pulling him back into her pussy, squeezing her eyes shut as that hot tongue slips back out and starts drawing little shapes on her clit again. “Fuck—“ Armin lets out a surprised moan at the taste that was covering his tongue with every press of it inside her quiverig hole, slowly falling into what he’d discover later to be a now desperate addiction. 

Eren walks behind her and starts kissing her neck, nipping and biting across Y/N’s collarbone with the intent of leaving marks behind as his big hands come up to grope at her chest. She turns her head to kiss him just as he twists one of her nipples through her shirt, and she moans directly into his mouth both from his touch and the feeling of Armin’s tongue in her pussy. Eren grins against her lips as they kiss wetly, never tearing his eyes from the man on his knees lapping at his stepsister’s cunt like an obedient bitch. 

Armin slobbers all over her cunt, slurping up as much of her juices as he could as she inched closer and closer to orgasm and her grip on his hair tightened, her other hand going up to bury itself in Eren’s long hair and squeeze so hard his scalp started aching. Her hips roll up into Armin’s mouth again as she starts desperately humping his face, just on the cusp of orgasm from his mouth alone. 

“C’mon baby, gonna cum, c’mon!” she whispers, rutting against his face desperately, “Don’t stop, ‘m so fuckin’ close, don’t stop!” 

Armin presses his face between her pussylips and sucks her clit into his mouth, shaking his head side to side a little like he’d seen in the videos he’d watched before sucking and nibbling at it and looking up at her through his eyelashes as her eyes rolled back and she let go of his hair with one hand so she could grab one of the higher shelves as she let out a drawn-out shriek. Her skirt that she’d had flipped up falls down a little and obscures his vision, but Armin just keeps sucking at her clit and drawing shapes on it with his tongue until she weakly pushes him away and tries to stand up on shaky legs.

“What — What a fuckin’ mouth you have there,” she murmurs tiredly, holding on to Eren in exhaustion. Her eyes, however, are still dark and expecting, and she glances to the room Armin had made into his bedroom before walking to it on shaky legs. “Eren, bring him to the bedroom. Our baby boy’s just earned himself a reward.”

Eren grins himself, a wide, sharklike thing that almost scares Armin, but the blond still follows the brunet when he crooks his index finger his way. He walks into his own bedroom to find his stepsister shimmying her cunt juice-soaked panties down her legs, her slit perfectly framed by her thighs and ass as she stands bent at the waist with one finger hooked into her panties, which are around her ankles. She lifts one leg out of it daintily, and the other follows, but Armin can’t tear his eyes away from the glistening entrance he’d gotten to taste only a minute earlier. Y/N kicks her underwear away from herself and strides over to his bed, laying on top of it and spreading her legs. 

“C’mere ‘nd suck my nipples, baby,” she murmurs softly, and he starts moving towards her almost automatically. He’s stopped by Eren, who puts a hand on his shoulder and looks at his clothes pointedly. 

“Don’t you wanna take those off first?” he asks, and Armin feels his cheeks heat up in nervousness that’s whipped away when he hears what comes out of Eren’s mouth next. “It would make us both so, so happy to see you — and you don’t want Y/N to feel cold all by herself like that, right?”

He’s stripped himself of his clothes before he even realizes it, and even when he does he’s rushing over to the bed and climbing up it. He takes his place between her legs and whimpers when she locks hers behind his lower back, pulling him close and pressing his face into her chest. He can feel the heat from the soft, delicate spot between her thighs that he’d dreamt about more than once ( and had berated himself for even imagining once he’d woken up ) rubbing against his hardened cock, and he whimpers at the feeling of the slight friction against such a sensitive place on his body. 

Y/N’s hand presses almost insistently against the back of his head, her fingers burying themselves in his silky hair and guiding him to her nipple, which he latches onto up laying his eyes on it. His mouth is hot, and she moans softly as he begins doing just what she’d wanted without her even having to tell him. Leaning down, Y/N licks off the juices she’d left on his face, her eyes glittering as he moaned against her breast, his tongue curling around her hardened nipple and his cheeks hollowed as he suckles. 

Armin lets out a surprised cry when Eren starts playing with his ass again, burying spit-slicked fingers up to the knuckle in his hole and stretching him out unforgivingly. Each thrust of the brunet’s fingers drove Armin further and further away from Y/N’s breasts, eventually pushing him up so he was chest to chest with her with his cock pinned between his and her bodies. The pressure made him whimper, his hips rolling up into her, and Eren carefully steadied him with one hand on his hip as Y/N brought his face down to hers so they could kiss. Her mouth was hot and wet, and she tasted faintly of cherries, which made him moan; it had to be from Eren buying her some cherry candy on the way there like he always did. 

Not even noticing that Eren’s pulled his fingers from his ass, Armin’s eyes cross as Eren presses his cock into the twitching hole before him, the blond’s thighs trembling as he tries his hardest to hold himself up despite the pleasure he was feeling as he was stretched wide. Y/N takes advantage of him being distracted to reach between their bodies and wrap her hands around his cock, pushing it inside herself and watching as his face contorts from the feeling of his cock being swallowed up by her cunt. As he reacts to her hole sucking him in, Eren doesn’t stop pushing inside him until his hips are flush with Armin’s plump ass, the older man’s cheeks dusted ever so slightly with a rosy color as stills and he fills out the hole he was using. Armin was fucking tight, and since Y/N didn’t like anal ( so they didn’t do it ) it was affecting him. 

He gives the trembling man ( no longer a virgin!! ) beneath him a moment to collect himself before carefully pulling out, stopping right as his tip tugged against the inside of Armin’s hole before slamming his hips back against the smaller blond’s. As he’d pulled out he’d slightly pulled Armin’s own cock from Y/N’s wet heat, which had drawn whimpers from the younger man’s mouth that had turned into a scream as he’d been filled by Eren’s thick length and surrounded by Y/N’s hot pussy. 

“O-Oh — Oh god, Eren! Y/N! I-It feels s’good!” he cries, his voice shaky and tears prickling at his waterline, tears that only threaten to grow larger and fall with each rough thrust of Eren’s hips. “F-Fu-uck ple-e-ease~! Hard-der, harder! Faster-r!” The bigger man’s balls slap against his own as he fucks him, slamming against his prostate and sending Armin’s cock deeper into Y/N’s hole with each thrust, and as a result Armin’s speech slowly begins to slur and his brains eases off; he doesn’ think about what’s being said or the taboo aspects of what’s happening, all he focuses on is how it feels good and how he never wants the pleasure he’s feeling to end. 

“D-Daddy, Mommy, please!” Armin wails, no longer even aware of what was coming out of his mouth, and as Armin clutches tightly at Y/N’s front, the two aforementioned people pause and lock eyes, a wicked glance passing between them before they look back down to the quivering blond between them. They both coo at him lowly, their experienced fingers trailing across his heated skin as he clings to them in desperation and cries out from how good he feels. 

“Bein’ such a good boy for us, Armin,” Eren purrs, gently biting at the back of the blond’s neck as he sobs beneath them. The tears have long since started falling, Armin not even aware of them with how wrapped up he is in the moment. Eren’s mouth moves from his neck to his cheek, his hot tongue darting out and licking a line up his face, collecting the tears that had fallen as Y/N murmurs her agreement. 

“Yeah, such a good slut for us, baby boy,” she whispers, kissing his other cheek. 

“M-Mommy-!” he hiccups weakly, shakily grabbing at Y/N’s shoulders and sobbing when Eren’s cock strikes him ( yet again ) directly on his swollen, sensitive prostate; the entire time that his stepsister’s boyfriend had been fucking his ass he’d been zeroed in on the sensitive stretch of flesh, and that coupled with the size and length of Eren’s cock made Armin lose his mind to the feeling of the other man completely rearranging his poor, abused insides. 

When he’d started cleaning his apartment that morning, this was not what he’d been expecting.

He lets out a sudden cry when he finally cums from all the stimulation, filling Y/N’s pussy with it and making her groan and let her head fall back on Armin’s pillows. The aforementioned blond goes limp, his vision hazy and his skin prickly with overstimulation and his hole clenching around Eren. 

Eren’s grip on his hips tightens exponentially as he gets closer and closer to cumming, and he glances up to see the blissed out face of his girlfriend and the fucked out one of her little stepbrother, who Eren had known had had a life-long crush on them both. Eren almost felt bad for taking advantage of him like this, but what could he say? This was different than Y/N fucking Jean or him fucking Jean every weekend ( the horsefaced fucker was borderline obsessed with both of them and had crushes on them for ages anyway, and Eren could willingly admit that he was at least a little bit attractive, so Eren had been fine with it when Y/N had asked ), this was Armin — they’d only ever get to do this once, and now was the best time since Eren had proposed last weekend anyway, they’d be a married couple soon. While Eren enjoyed their romps outside of their relationship, he much preferred keeping to his own girlfriend for good rather than keeping them up. 

With a pointed grunt sent his girlfriend’s way, he leans down close to her, pressing Armin almost flat so his lips can meet Y/N’s. Y/N and Eren kiss feverishly with a whimpering Armin tightly sandwiched between them, cum leaking from Y/N’s hole where Armin had cum, and more cum smears between their bodies when one extra brutal thrust pulls Armin’s sensitive cock from her depths to slap wetly against her stomach. The blond lets out a shaky sob as the cool air practically attacks his spent cock, and with a loud roar that’s muffled by Y/N’s mouth and several shakily whispers of, “I love you!” from Eren, the man cums hard, his seed flooding Armin’s ass and making the man whine at the feeling of sudden warmth filling his insides. 

Eren’s pulling out not even a full thirty seconds after cumming, and he ignores the way his cock begins twinging with his own overstimulation; he wasn’t in a relationship with Armin, he was in a relationship with Y/N, so he had no reason to let the blond cockwarm him. That being said, he does fish the plug he’d brought with him out from his back jeans pocket and press into into Armin’s puffy, swollen red hole; he may not be keeping the blond full with his cock, but he’d be damned if the little smartass was going to waste the cum he’d pumped him full of. 

Armin’s unconscious when Eren carefully ( though also carelessly ) pulls him off of Y/N, and he walks with her to Armin’s bathroom before sitting her on the toilet and carefully beginning to clean her up with a warm washcloth and gentle hands. Her own comb through it long, soft hair affectionately, and he smiles up at her with nothing short of pure love shining in his eyes. She smiles down back at him, and he finishes cleaning her up before walking her to the living room. They both glance into Armin’s bedroom to see that he’s still unconscious, and Eren kisses Y/N on the lips three times in quick succession while whispering, “I’m gonna go grab us something to eat — should I get him something too?”

“Yeah, he’ll be hungry,” she murmurs, letting him drape himself over her front like a big, limp bear. She could feel him tracing shapes across the expanse of her back, and could hear him mumble something, but she didn’t know what exactly. “Hmm?”

Eren shifts nervously. “Love you,” he says pointedly, and she smiles softly to herself. He always got this way when they had a fling, even when on the weekends when they slept with Jean; he always needed to let her know that she was his only love, almost as if he didn’t know that she knew already. 

Regardless, his habits of repeating how he loved her and his sudden increase in clinginess never failed to make her smile. 

“I know,” she whispers, running her hand up the length of his shoulders and neck so she can cup his face in one hand while bringing it down to gently ghost her lips across his. She presses their foreheads together, their noses pressing against one another as well, and says, “I love you too, Eren.”

As usual, he melts. 

They stay like that for a while, simply basking in the feeling of holding each other, before he finally disentangles himself to get the food he’d mentioned several minutes before. Y/N busies herself with making a pot of coffee in the kitchen since Eren enjoyed drinking coffee with most meals, regardless of the time of day ( Mr. Ackerman had even bought a specialty coffee machine for the breakroom on Eren’s birthday two years ago just for him before telling the rest of staff they could have tea and that ‘the machine was Yeager’s’; the raven haired man had also turned a color similar to that of a strawberry when Y/N had kissed both of his cheeks fondly after watching Eren’s eyes light up excitedly, and his tall blond boyfriend had chuckled at the sight ). 

As Y/N sips at Eren’s cup of coffee as she always did, Armin stumbles into the kitchen. By this time he’d slept for over an hour, and Y/N quietly wondered if he’d even noticed the blue plug that Eren had shoved up his ass or if he was still too sore to notice much of anything. 

“Eren ran out to grab us all something to eat,” she explains before he even asks, “He knows well that people tend to get hungry after times like that.”

Armin blushes, rubs at his eyes, and nods before his eyes lock on Y/N’s hand and widen in shock. He swallows hard and fights back sudden tears that he’d not expected after waking up so pleasantly used like he’d dreamed about for years. The sparkling diamond ring on her finger seems to mock him, and he looks up at her questioningly. 

Y/N sees the look on his face ( but not the look in his eyes ) and smiles over Eren’s mug of coffee.  “He proposed last weekend when he took me on that picnic beneath our tree,” she says, looking down at the ring on her hand with warm eyes. “He says we’re gonna move to the inner ring for when he works in Paradis Memorial — he’s already put the downpayment on a house for us, two floors and a basement, three beds, and four baths. It has a big, big yard, and we’re gonna paint a pretty mailbox of our own; he’s even gotten some new furniture for us,” she sighs, her smile fond and her eyes dreamy. “This is it for us, Armin — me ‘nd Eren, we’re making it in the world together, just like we’ve always wanted.” And as Eren re-enters Armin’s apartment, Armin’s heart cracks — because if they were moving so far away and so up in the world so soon in the future, after all that had just happened, what time could they possibly ever have for him? Armin couldn’t possibly afford to follow his stepsister to the inner ring, there was no way, so he would just… be left behind? Even after what they’d done together?

Yes, that’s definitely what would happen, because looking at the two of them pressed so close to one another and clearly so in love, Armin refused to break that picture apart — just like he’d done for the past eight years.
