୨୧˚ an ⇀ eren has a crush on armin because i said so.

THE room was stifling, air thick and stained with the heady scent of sex. armin sat at the foot end of your queen sized mattress, dressed from the collared shirt buttoned around his toned chest, down to his khaki slacks and black socks. he was knelt, sat back on his hind legs, and you couldn’t help but admire the way the pants material strained against his thighs. nothing looked out of the ordinary, save from the brown, leather belt that had been popped open, its excess length dangling from the belt hoops at his waist.

“eren, c’mon.” armin’s voice was soft, yet so very stern it made your lungs quiver with unshed breath. through blurry vision, you could vaguely make out the blonde’s form, a single hand thumbing open the button of his slacks and sinking past the waistband of his cerulean briefs. “go a little faster.”

the opposite end of the bed was occupied by eren and yourself. he had you on your hands and knees, two pillows stacked beneath your tummy. eren was completely nude, at armin’s request, but you were instructed to keep those, in his words, “sexy little panties on.” the black, lacy thong always seemed to rile armin up. eren, too, always seeming to hold the thin material to the side with his thumb while he fucked into your cunt from behind.

“fuck up,” eren grunts, bringing a wrist up to his forehead, wiping at the beads of sweat pearling along his temple. “don’t tell me how to fuck my girl.”

armin let’s out a quiet huff, and you’re able to see the way his forearm flexes with exertion as he stroked himself within the confines of those irritably tight pants. “why can’t you ever just listen to me?” he asks with a humorless chuckle.

“you’re never—hah—fucking satisfied.” eren uses a brute palm, pushing it against the small of your back. he loves to see your spine bend and mold to his adjustments, and slams his cock excitedly back inside, earning himself a sexy mewl and a weeping gush from that pretty lil’ pussy. “ain’t it enough that i let your weird ass watch?”

armin licks his dry lips, letting his free hand walk up his flat tummy. his thumb brushes over his own nipple, making a show of how truly turned on he was. “no.” armin approaches you and eren, shuffling on his knees with his hand still buried in his pants. “can she suck me off?”

they discussed this like you weren’t laying right there. eren halts, shoving himself to the deepest part of you before pausing to shoot armin the meanest mug. “hah?”

“y/n,” armin clarified like it was obvious. blonde brows furrow in desperation, “please let her…”

eren stared at armin with such vigor, you feared he might throw a left hook to armin’s jaw. “eren…” you choked out cautiously. what you weren’t expecting was the brunette to snatch armin’s hand out of his pants, replacing it with his own.

“jesus, you’re like fuckin’ diamond down there,” eren laughed breathlessly, raking his unoccupied hand through his lengthy, sweat-soaked locks.

armin’s cheeks were pink, but he leaned his groin into eren’s palm shamelessly. “yeah, well,” ocean eyes dragged over the expanse of your twitching back, zeroing in on the glistening area of eren’s navel, sheening with your slick. he felt his mouth water, a nasty urge telling him to lick eren clean. “your girlfriend is really pretty.”

“she is,” eren whispered with a teasing smile. with a hint of reluctance, eren withdrew his hand from the warmth that was armin’s boxers, holding up his fingers to admire his precum-glazed fingerprints. “messy,” eren tuts, wiping the semen on armin’s disheveled button down. the latter let him, already making a move to unbutton the garment anyway.

finally, you had been included in the conversation when eren pulled you up to him with a painful grip on your hair. he’d collected your locks in a makeshift ponytail, as to not yank any of your roots and hurt you any more than he knew you could take. you arched, back bowed wickedly as eren brought you close. “you wanna suck ‘min’s dick? he’s pretty big.” eren rubbed a calloused hand up your stomach to blanket over your tit, giving it a healthy squeeze. then, a sweet kiss to the back of your ear. “up to you, babe.”

armin already had his shirt off, discarding it on the floor of your bedroom. he was panting already, chest heaving, pert nipples pink and flushed. he didn’t verbally push you, but armin had the worst case of puppy eyes you’d ever seen. “is… is it really alright with you?” you wanted confirmation that this wasn’t some sort of trick, lest you say yes and eren gets pissed off at your readiness to suck another man’s cock.

“mm,” he hummed in confirmation, nuzzling the point of his nose against your jaw. “i trust armin. he’ll be gentle with you.”

in the background, armin’s nodding. “i’ll be so gentle, i promise.” and you’re inclined to believe him. armin had always been the sweetheart of the friend group, and you’d be lying if you said you hadn’t found his kindness towards others a little attractive.

“okay,” you agreed with a small grin. armin’s face lit up the tiniest bit, and with clammy yet confident hands, armin brushed his knuckles over your damp cheekbones, an intimate gesture that warmed you up inside.

eren was quick to smack armin’s hands away from your face. “aht aht, none of that sweet shit,” he scolded, petting his hand over where armin’s touch had tainted your precious cheeks. “no kissing, either. you hear me?” eren squished your face with one giant hand, turning your head to the side so he could look you in the eye. “don’t kiss him, only me.”

“only you,” you said through your puckered lips, drawing a proud smile from your boyfriend. he pecked your lips before releasing your face, pushing you back down to rest against the mouth of pillows.

“‘min, pull it out.”

“yeah, yeah okay.” armin nods, shoving his thumbs into the waistband of his slacks before slowly slipping them down his hip bone. not bothering to take them all the way off, just enough to release his bulge. that clammy hand found residence underneath your jaw, angling your head up to look you in the eye. “you wanna see it?” armin breathed, head tilted as his free hand massaged over the bulge in his blue boxers.

his lewdness was horrifically shocking, but you swallowed that emotion down in favor of gnawing at your lower lip. “yes please.”

armin swore he died for a second. “isn’t she so polite?” eren asked cockily, revving up his hips again in slow, languid strokes. not enough to inebriate you, but still enough to keep up the pleasure. you preened, lips parted in quiet moans.

“so polite,” armin agreed quietly, trancelike, as he fished his erection out from the confines of his briefs. eren wasn’t kidding, armin was a decent length. all pink and veiny and smooth.

eren watched intently from his place behind your ass, unable to stifle his laugh. “holy shit, bro do you wax? how the fuck are you so smooth?” ever the extrovert, eren reached across your small body, running the back of his palm over armin’s pubic bone, only to gawk at the creamy texture of bare flesh.

armin lets eren touch, almost like he’s used to the man’s hands, and blushed. “i like the clean look,” he manages a shrug, swatting eren’s hand away. armin let’s his palm graze over your nape, sliding up to weave those long, pale fingers into your tresses.

“suck him, baby,” eren coos from behind, giving a little squeeze of encouragement to your ass. “or i might.”

armin rolls his eyes, “‘ren, shut—oh.” you’re down there, ever so gently taking his appendage into your small hands and pressing feverish kisses up the underside of his pretty cock. the fingers in your hair tighten for a nanosecond, his blunt nails scratching against your scalp.

unbeknownst to you, too busy spitting on armin’s dick, eren is smiling wolfishly at the sight before him. “yeah, there we go,” he groans, sending a smack to your ass in between thrusts.

“mmfph—!” muffled through armin’s flesh, you cry at the sting of a steel palm against your ass cheek. the vibrations from your hymn have armin gasping.

“oh, that felt really nice.” he announces through a quivering voice.

“she’s good, right?” eren asked.

armin nods, “the best.”

eren likes that answer. amidst the dicking down he’s giving you, eren finds a grasp on the back of your skull, his hand flat atop armin’s that already resided there. armin shoots eren an incredulous look. the brunette just licks his teeth.

“c’mon, make him moan,” eren demands, suddenly forcing your head deep into armin’s lap. the both of you are caught off guard. you’re choking around the satin-covered rod that lodged into the depths of your throat, and armin equally sputtered on his own spit, releasing a bitchy moan of his own. eren looked at you two with hearts for eyes, too turned on to think. “take him deeper, y/n. to the f—hnn, fuckin’ balls.”

you gagged, saliva bubbling past the barrier of your lips and leaking down to wet armin’s khakis. he couldn’t give less of a shit, too busy steeling his stomach, focusing his entire being into not cumming down that tight, wet throat of yours. “e-eren, she’s choking,” armin said between hiccups and whines, pawing at eren’s wrist that was attached to the hand planted on the back of your head. “ease… up!”

eren sneered, “she can take it. jus’ a little more.” eren felt himself get close. the heavenly feeling of your sopping cunt in tandem with the sexy scene of you gagging on armin’s cute cock… jesus, he really was about to cum. “c’mere,” eren ordered to armin, not even getting a chance to form a thought before eren was reeling him in with his free hand on the back of his neck.

the men met, their lips crashing roughly against one another. eren grunted into armin’s cavernous mouth, dragging his nails down the side of his delicate neck. “fuck,” eren hissed, decimating the latter’s mouth with his long tongue. armin desperately tried to keep up, but as his orgasm approached, the delirium only grew. armin let his jaw unhinge, allowing eren’s tongue ti mesh against his own.

spit dribbling down his chin, stringing down to stick against his sweaty, beet-red chest. “er…” armin whimpered, eyes rolling back in his skull. armin’s hand grabbed blindly for eren’s hair, yanking it without any of the delicacy that he’d treated you with. “i’m c-close…”

“cum in her throat,” eren whispered against armin’s swollen lips, kissing him again. “y/n, y’ hear that? drink it.”

you could barely breathe down there, not with the way eren was so adamant about you swallowing down every inch of armin. all this time, eren had been the one concerned about whether or not armin would treat you gently, just for him to be the rough one all along. he knew you loved it, though. “hngg,” was all you could say with seven inches in your throat and eight in your cervix.

“good fucking girl,” eren praised, giving armin one final sloppy kiss. “n-nut in her mouth.”

the idea sounded so delectable, but armin was apprehensive. “will y/n—”

“she loves it ‘min. nut in her goddamn mouth.” the brashness of eren’s nasty words had sent armin full throttle into his impending orgasm. those wide eyes screwing shut, lips parted and the girliest moans ripping from deep within his chest. armin gripped onto eren’s hair and broad neck for dear life, digging his nails into the sweaty flesh there.

at the same time, you’d felt your own orgasm burst at the taste of armin. his flavor was inexplicably clean, like water paired with a hint of salt and tang. the musky liquid had shot so deep into your throat, the little bucks of armin’s hips had involuntarily pushed the semen out through your nostrils. you cried, forcing your hips back to meet eren’s relentless movements and riding out your intense orgasm.

“she’s cumming,” eren called out in a moan-laugh hybrid, still ruthlessly slamming his hips against your wobbling ass. he snatched a chunk of blonde hair, ripping armin’s head out from when he’d buried it in the brunette’s neck and forced him to look down at your writhing, pathetic body. “look, my girl’s creaming all over me.”

armin watched, hazy and exhausted but still conscious enough to admire the attractively feminine lure of your hips as they twitched from pleasure. “wow…” was all he could stupidly say, invested in the way your asscheeks valiantly bounced off eren’s chiseled hips.

speaking of, eren was on the cusp of his own ferocious climax. he tended to get giggly when he was close to bursting, and you couldn’t miss the way his cock throbbed inside of you. “fuck,” eren pulled out hastily, slapping your ass. “on your back, quick.”

with armin’s gentle help, you maneuvered yourself one hundred and eighty degrees, kicking the pillows out of the way to lay perfectly flat. armin knelt beside your head, whilst eren shifted himself to straddle your tummy. reaching an impatient hand up towards armin, eren snapped a finger. “hand.”

it was a simple demand, one armin was quick to fulfill. he lended eren his limp hand, knowing exactly what it was about to be used for. you watched as eren curled armin’s fist around his cock, breathlessly telling armin to stroke. “squeeze it tighter, i’m not gonna break.”

armin chirped out an apology, adjusting his grasp on eren’s dick. eren grabbed the man’s shoulder in one iron-clad grip, the other one pinching your nipple. eren’s eyelids flutter shut, expelling grunt after grunt. “close,” he uttered, tossing his head back, “aim it at her tits.”

armin did so, picking up the pace and making sure every drop of eren’s cum collided with your satin chest. the corded muscle of eren’s thick thighs flexed, back arching as he reamed himself into armin’s soft hand. “oh my god fuck yes!”

after coming down from his stellar high, eren assessed the damaged. armin was spent, looking exhausted as all hell, but blissfully content. you, his perfect girl, were sheening with sweat, hair mussed and breasts drowning in a thick layer of his seed. “look at this mess,” eren hummed, rubbing his cum into your skin like moisturizer. “you’re all sticky.”

“i don’t mind,” you smile weakly, more than happy to be doused in your boyfriend’s baby batter any day of the week. but eren tsked, shaking his head frivolously.

“i mind.” those narrow, seafoamy eyes of his flitted over to the only other male in the room, “armin, why don’t you come clean her up. slowly, i wanna watch.”

the umpteenth bashful smile tugged at armin’s lips, spit-soaked lips curving gracefully around his words.

“i’d love to.”
