I'm So In Love

Summary:

Eren and Armin have hot, nasty sex for ~2000 words
(they're deeply in love with each other, your honor)

Notes:

Armin’s genitals are referred to anatomically correctly, while also referring to his clit as his dick as well. Writer (me) is transmasculine, so I’m hc’ing his comfort level as my comfort level with certain terms :)
(terms like clit, cunt, dick (referring to his bottom growth), pussy, and labia will be used to describe Armin’s genitals in this fic)

It's been a year since I last wrote and published anything on here, and I'm glad to be getting back into my groove. I hope to write more Eremin in the future, as they are my current obsession. I hope y'all enjoy, and feel free to leave any suggestions you might like to see in a future fic if you enjoy my writing, I thrive off praise

Work Text:

Armin lets out a breathy moan on his boyfriend’s lap, throwing his head back as Eren sucks and bites the side of his neck, rolling his hips down into Eren’s crotch as he kitten licks the now-red hickey. 

Eren moans into Armin’s neck. “Fuck, Armin, you can’t keep doing that,” Eren all but whines as he moves to another spot on his boyfriend’s neck.

Armin glances down at Eren and giggles. “Sorry, I can’t help it!” He excuses, letting out a sigh as Eren bites down on him again.

Eren looks up at Armin, and cupping Armin’s cheek with his hand, pulls his boyfriend down into a ravenous kiss, in which Armin fervently returns. Eren bites and pulls at Armin’s lower lip, earning a gasp from the other man. 

Armin pulls back slightly, raising an eyebrow at Eren. “What’s gotten into you today? You’re so,” Armin pauses to find the word he’s looking for, “bite-y.” He teases Eren with a chuckle. 

Eren smiles up at his boyfriend. “Nothing! You just look extra edible today,” Eren winks at him, grasping at the back of Armin’s neck and pulling him back down to meet his lips again. Eren slowly kisses Armin, eventually pushing his tongue into his boyfriend’s mouth. Eren glides his hands down Armin’s sides, grasping his hips and rolling Armin down to meet his clothed dick, both men letting out small groans at the friction.

Armin slowly pulls away and gets off Eren’s lap and off their shared bed, Eren’s hands unconsciously following his boyfriend. “Help me get my clothes off?” Armin smiles at him.

Eren silently nods, pulling Armin’s shirt up and off his head, and next goes for his sweatpants, where he sees Armin isn’t wearing any boxers. Eren lets out a low groan at the sight of his boyfriend’s engorged clit, reaching with his fingers to lightly trail his nails on it, making Armin let out a sharp moan and quickly grasp his shoulder to stay upright. 

“Oh, fuck,” Armin moans out, roughly grasping at Eren’s clothes to help him get undressed as well. 

Eren chuckles, allowing Armin to help him be rid of his tank top, boxers, and lounge shorts. Eren is already hard, which Armin drools at. Eren sits back down on their bed, pulling Armin over his now naked thigh. Grasping Armin’s hips with his hands, Erens pulls his boyfriend down onto his thigh, Armin letting out a gasp as his exposed clit makes contact with his boyfriend’s warm skin. 

Armin sits still, looking at Eren for further instruction.

“Well, go on,” Eren nods, smirking, “ride my thigh.” 

Armin blushes and wraps his arms around Eren’s neck as Eren keeps his own hands on Armin’s hips. Armin leans into his boyfriend’s ear, whispering, “Sure, but only if you help me,” and slowly starts to roll his hips onto Eren’s exposed thigh, nipping at his earlobe. 

Eren gets the hint, gripping Armin hard and dragging him down harshly against his thigh, Armin choking on a moan and clawing at Eren’s shoulders. Eren nips at Armin’s chest as he forces Armin to grind against his thigh, smiling at the whines Armin lets out. “Feels good on your dick, hm?” Eren innocently asks, lightly biting down on one of Armin’s nipples. 

“Y-yeah!” Armin gasps, tightening his legs around Eren’s thigh. Armin brings a hand into Eren’s hair, tugging lightly, signaling for Eren to lift his head from his chest. “Fucking kiss me,” Armin breathes out, staring at Eren with lust-filled eyes.

Eren can’t help but oblige, kissing Armin roughly, stealing his breath. Eren tenses his hamstring as he rolls Armin’s hips downward, making Armin gasp into his mouth. Eren holds Armin’s hips in a bruising grip as he licks into his boyfriend’s mouth, making Armin tense in his grasp. “C’mon, baby, cum for me. You can do it.” Eren encourages.

Armin’s breathing picks up as he grinds himself quicker on Eren’s tensed thigh, moans pitching up in tone as he comes closer to orgasm. “Oh fuck, Eren! I-I’m gonna- I’m gonna cum!” He exclaims in desperation. 

“Good boy,” Eren praises, biting down on the juncture of Armin’s neck as he orgasms, curling in on himself.   

“Fuck, I love you,” Armin pants into Eren’s hair, catching his breath as he holds Eren close to his neck. 

Eren chuckles, rubbing his hands up and down Armin’s sides lovingly. “I love you, too, ‘Min,” he replies. After a moment of caressing one another, Eren turns them both to the side, moving his hands to lower Armin down onto their bed slowly. “You down for another round?” Eren asks mischievously, now hovering over him. 

Armin’s hair fans out around his head like a halo, making him appear angelic. Armin smiles unabashedly up at Eren, nodding eagerly. “You don’t have to ask me twice,” he replies with a grin. 

Eren holds himself up over Armin with one arm, while reaching down with his other to gather Armin’s cum and lightly circle his clit, making Armin gasp and grab at his wrist. “You’re so wet, baby,” Eren teases, “is this all for me?”  

“O-only for you,” Armin agrees, nodding as he squeezes his eyes shut in pleasure. Overstimulation starts to kick in, pulling sweet moans from his lungs. “Please just fuck me already, I need you,” Armin pleads with him, tears forming at the corners of his eyes. 

Eren intentionally dips his fingers lower, lightly pushing into Armin’s pussy, moaning at how wet and hot Armin is. “I can never say no to you,” He says, pulling his fingers away and putting them into his mouth. 

“Oh shit,” Armin whispers, watching Eren suck his own cum off his fingers.

Eren smirks, reaching between them once more, gathering more of Armin’s cum in his fingers before spreading it along his neglected cock, moaning loudly as he pumps his fist a couple of times as he hovers over Armin, lining himself up with Armin’s pussy. “You ready?” He asks, already knowing the answer, yet wanting to tease Armin just a little more.

Armin wraps his legs around Eren’s waist, making it impossible for Eren to pull away. “Yes! Yes, please just fuck me!” Armin begs, pressing his heels against Eren’s back, pulling him in. 

Eren chuckles, allowing himself to be pulled forward, pressing the tip of his dick into Armin’s wet hole. They both moan simultaneously as Eren pushes forward into Armin, his head dropping, now touching his forehead with Armin’s. 

They pant heavily in each other’s faces as Eren fully sheathes himself inside Armin, stilling to allow Armin time to adjust. 

Eren leans down and pecks Armin’s lips with his own, smiling softly at his boyfriend as he watches Armin’s face contort in pleasure. “Am I okay to move?” He questions softly, bringing his hand up to brush hair from Armin’s sweat-slicked face. 

Armin gulps, catching his breath, and nods lightly, looking into Eren’s eyes. “Ye-yeah, yeah, I think I’m good,” He confirms, lightly scratching his nails down Eren’s back, making the man shiver. 

Eren leans back, taking his thumb and pulling on Armin’s labia. He pulls out slightly, seeing his dick sit inside his boyfriend’s wet cunt, letting out a low growl. “Fuck, Armin, you take me so well,” he praises, Armin letting out a whine at the praise. Eren starts to fuck into Armin with shallow movements, continuing to watch his dick slide erotically in and out of his boyfriend. 

Armin keens, arching his back in pleasure. He reaches down for his own dick, and Eren intercepts him, forcing his arm over his head and holding it there.

“Oh no,” Eren shakes his head. “You’re gonna wait. I know you can take it,” Eren smirks down at him, pistoning his hips at a bruising pace. He shushes Armin soothingly as he loudly cries out, squirming under Eren as tears fall down his reddened cheeks. “It’s okay, I’ll take care of you,” Eren coos, caressing Armin’s face softly with his free hand.

Eren, please,” Armin begs desperately, staring into Eren’s lust-ridden eyes. 

Eren leans down and kisses Armin sweetly, still keeping up a fast pace. He takes his hand from Armin’s face, licking his fingers erotically before moving them between the two to pull on Armin’s clit in fast strokes. 

“Eren!” Armin’s back arches harshly as he chokes on a scream, his orgasm hitting him so hard his vision whites out, squirting on the sheets beneath him, soaking them. “Fuck, fuck, fuck!” He chants as Eren’s hips begin to stutter, as Armin’s soaking cunt clenches and unclenches around him, chasing his own high.

“O-oh shit! I’m cumming,” Eren groans, sinking his teeth into Armin’s neck as he spills his semen inside his boyfriend, panting hard. Eren releases Armin’s neck as he slows, staying seated inside him as they both recover. “Holy shit, that was hot… You are so hot,” Eren breathes out, looking down at the mess between them, feeling a sense of pride wash over him. 

Armin weakly slaps Eren’s chest as he observes Eren looking down at the mess he made. “You weren’t that good,” Armin lies with a sly grin, watching Eren’s head snap back up to meet his eyes. 

Eren narrows his eyes at Armin. “Oh, so that’s how it’s gonna be?” He challenges, pulling gently out of Armin before lowering himself between his boyfriend’s legs, grasping Armin’s thighs tightly before roughly yanking Armin’s core towards his face, latching his mouth around Armin’s clit and sucking, hard.

Armin’s yelp of surprise turns into a loud moan, tears pricking his eyes. He curls his fingers in Eren’s long brown hair, pulling at him as overstimulation takes over. “Fuck, Eren! ” He pleads, his chest heaving as his eyes roll back into his head. 

Eren smirks as he eats Armin out, tasting his own orgasm as he dips his tongue inside his boyfriend’s cunt, eating him out earnestly, like he’s about to die and Armin is his last meal. He growls into Armin’s pussy, keeping a bruising grip on Armin’s thighs, keeping him stuck in place as he doesn’t slow down, Armin’s loud mewls and cries further encouraging him. “Damn, you taste good,” Eren praises, swirling his tongue around Armin’s dick, sending Armin closer and closer to his third orgasm of the night. 

D-don’t stop, fuck! ” Armin cries out as Eren sucks on his clit harshly once again, taking one of his hands and slipping a finger into Armin, curling upwards. He hears Armin go silent, glancing up to see his back arched, mouth slack in a silent scream, as he cums again. Eren fucks him through it, gently laving his tongue on his clit as Armin collapses back against the bed, panting harshly and pushing at his head with the hand that was curled in his hair. Eren gets the hint, unlatching from Armin’s clit and delicately pulling his finger out of him. 

Eren crawls up the bed to wrap Armin in a gentle embrace, kissing his forehead as he whispers praises in his ear. “Did so good for me, ‘Min. So good.” He soothes as Armin catches his breath, nuzzling into Eren’s chest. 

Armin opens his eyes, looking up at Eren as he smiles sweetly, blinding Eren with his beauty. Armin lets out a contented sigh. “That was fun,” He rasps out, giggling as Eren peppers his face with light kisses, squirming closer to Eren. Armin settles, closing his eyes and says, “I love you.”

Eren smiles, “Love you too, always,” he repeats to Armin. He starts to untangle himself from Armin, and he whines, grasping harder at Eren. 

“No, don’t leave.” Armin pleads.

“It’s okay. I’ll be right back, gotta clean you up, baby.” Eren tries to rationalize.

“You already did!” Armin giggles, not showing any signs of letting go.

Eren sighs in defeat, knowing he lost, and resettles back in bed, wrapping his arms back around Armin. He pets his golden hair gently, scratching at his scalp, and he hears Armin let out a pleasured sigh. 

Eren decided he could stay there forever.
