Chapter Text
It’s been about a month and a half since Armin had sex with Eren at a Friday night frat party. And since then, the two have had sex with each other approximately 28 more times after that night.
It’s not like Armin’s been keeping track, it’s just hard to forget every separate instance where Eren has touched him, or spanked him, or bit him. Sex with Eren plays in an unstoppable loop in Armin’s head. The two have become insatiable for each other’s touch and they can start going at it with just a simple look or some dirty words. A true hunger that cannot stay fed.
It started simple. Every other night or so one would just climb into the other’s bed, and with a few soft kisses their clothes would be off.
Then, they started hopping into the shower together. The hot steaminess of it all was notably more fun than fucking in bed. And after that, fun became the main focus.
Experimenting with handcuffs and rope, toys and role play; all mostly by Armin’s request. But he felt the most disgusting when they’d do it in public—parties, bathrooms, locker rooms—which meant those were Armin’s favorite. Soon enough, blowjobs had basically become Armin’s way of saying good night to Eren.
Something strange had developed in Armin since that night. Eren told him he’s gotten more confident, Mikasa commented that he always seems out of it. But Armin, he feels an emptiness. A hole that he’s dug out of his chest, and is desperately trying to refill.
Tonight, alcohol is Armin’s choice of fulfillment. A futile substance, but no harm included.
“Do you think I’m a slut?” Armin inquired, his breath hot with liquor and the glass "bottle pressed against his chin.
“Pfft!” Eren spat a laugh. “You’re not a slut. A slut is someone having a lot of sex with, like, multiple different people. You’re just having a lot of sex with one person, there’s a difference.”
“Hmm.” Armin hummed from his spot on the couch, his body nearly limp against the cushions. “So with your definition then that makes you a slut.” He mumbled a giggle as the glass bottle pressed against his lips and liquor was tilted into his mouth.
“I prefer the term social butterfly.” Eren grinned, following Armin’s motion and taking a sip of his drink. “It’s still kinda weird seeing you drunk. It’s like watching an angel do a line of coke.” Eren admitted with a chuckle as he turned his head to watch Armin swallow down in drink.
“It shouldn’t be weird for you,” Armin started as he tossed his head to look back at Eren. “You’re the one who made me dirty.” His words had a tiny slur to them and his lips turned into a small smirk.
“I didn’t make you anything. I just took you to a party.” Eren shrugged and smirked back.
“Right, right. You just took me to a party where you shoved my first drink down my throat, handed me my first blunt, and then took my virginity. You’re totally not responsible for anything.” Armin punctuated his sentence with an eyeroll and another sip.
“Firstly, you basically begged me to pass you that blunt. Secondly, you told me you don’t even care about the concept of virginity, so don’t act like you were saving it.” Eren argued, once again taking another sip.
Armin brought his legs down to swing them off the edge of the couch, the extra length to his sweatpants brushing against the floor. “Well I still cared a little—everyone still cares a little.” Armin shrugged as his drunken eyes studied the glass bottle in hand.
“I remember when you lost your virginity.” Armin started to reminisce. “It was our Sophomore year of high school and when you told me you were cheesing like you had won the damn lottery. You told me pretty much every detail, probably because I asked for every detail. I can’t remember her name, but I remember you had a grossly huge crush on her. Like, after you fucked you literally changed your profile to a picture of her. Then she dumped you like a week later ‘cause you were too clingy!”
Armin snorted a chuckle, which developed into an irony filled cackle. Eren nodded painfully along with Armin’s laughter, finishing off his drink.
“You know, I actually don’t think I remember her name either.” Eren stifled a chuckle.
“Of course you don’t. How come she got ‘too clingy’ Eren and I got slut Eren? Doesn’t sound fair to me.” Armin huffed.
“What, are you not satisfied with slut Eren? ‘Cause that would be a lie.” Eren snarked.
“Hmm, but you have so much more experience compared to me. Have you ever thought I might only be so satisfied because you’re my only exposure to it? Those just aren’t fair grounds.” Armin brought his legs back up to a criss cross position.
Eren couldn’t help but stutter an offended scoff. His lack of a comeback made Armin’s lips grin mischievously.
“And tell me, who would you possibly have sex with that could compare to me?” Eren questioned as soon as his cockiness returned.
Armin’s eyes searched the room to think about his answer, a small snicker forming once a name came to mind. “Jean… Jean Kirstein.”
“Oh, you’re definitely drunk.” Eren scoffed, his voice containing a hint of bitterness that kept Armin entertained.
“No, I’m serious.” Armin continued, tucking chunks of hair behind his ear. “He’s already begging to fuck me. He likes all my posts like minutes after they upload. He slides up on my stories with cute little hearts and heart eyes.”
Armin watched as Eren’s eyes squinted into that fake unimpressed look. “Maybe I should respond next time.” Armin thought out loud. “I could text him, act like I’m dying to come to another frat party and ask if he could show me around this time.”
Armin formed another playful snicker, Eren’s disgruntled silence making him want to push his limits. “Or I could play the cute nerd card. I bet he’s behind in a bunch of classes, I’ll tell him I’m looking for people to tutor and he’d agree in a heartbeat. Frat boy jocks love that shit. Either way I could get Jean in my bed no problem. Plus he’s cute, tall, strong…and nice. I bet his dick is—“
Armin cut himself off with drunken giggles as Eren began to walk away. “I’m joking, I’m joking! Come back!” He called out, but Eren continued to leave the room. “Eren, it was just a joke, why are you getting mad about it.”
“I’m not mad.” Eren called back, tossing empty bottles into the kitchen trash.
“Oh.” Armin hummed, his back slumped against the couch and his fingers adjusting his glasses. “Well you shouldn’t be mad. Because you go around fucking other girls all the time and I never get mad. So if I fuck someone else you can’t get mad.”
“I won’t get mad.” Eren shrugged. He made his way closer to Armin’s spot on the couch, planting his arms beside Armin as he stood over him. “You’re not gonna fuck anyone else ‘cause you got me right here.”
Armin fixed his gaze upward towards Eren, whose face inched closer. “Ugh, how can you be so goddamn arrogant?” Armin’s eyes flickered down to Eren’s lips for only a second before they were pressed together.
Soft kisses didn’t exist between Eren and Armin. Every connection of their lips was filled with hunger and aggression. Eren’s hand reached through Armin’s blond hair to grab onto the back of his neck. Armin’s jaw widened to allow the kiss to deepen.
The hard metal of Eren’s piercing clicked and clanked against Armin’s newly acquired matching pierced tongue. Armin’s teeth sunk into the wet flesh of Eren’s bottom lip, as his hands eagerly pulled at Eren’s shirt to get it off.
“You say I’m arrogant but you can’t get enough of me.” Eren snarked as he pulled away to slip out of his shirt. Armin watched as the shirt caused Eren’s loose bun to become undone, his brown hair draping down his neck and over his shoulders. Armin always felt like Eren’s hair gets longer every time he takes it out of that bun.
“Keep it down.” Armin requested as Eren had begun to redo the ponytail. He obeyed without question and their lips found their connection.
Armin had memorized the way Eren touched him when they kissed. First, one hand would tuck underneath his shirt. Then the hand would feel up and down Armin’s torso until finally landing on Armin’s hips so he could move him into whatever position he wanted.
This time, he pulled Armin until he sat on the edge of the couch cushion. The next hand would start on his hip, rubbing downwards until he could get a grip on Armin’s ass—or this time his upper thigh.
The routine felt so natural. Eren’s touch had become a part of Armin’s daily life, he felt bare when he couldn’t receive it.
Eren’s kisses traveled away from Armin’s lips and towards his jaw, then his neck. Armin’s collarbone was usually the barrier where Eren's bites and hickeys stopped, but his body began to lean lower and lower until he sat himself down on his knees in front of Armin.
“This is different.” Armin announced, mostly out of confusion. “That’s usually my position.” He chuckled.
A smirk painted Eren’s mouth and his eyes found Armin’s intent gaze. His index finger twirled the string of Armin’s sweatpants while another finger tucked under the waistband, tugging until the area of skin underneath Armin’s belly button was exposed.
His tongue trailed across the small area of skin. Breathy gasps reacted as Eren’s teeth sunk into the sides of Armin’s hip bones. With another tug, Armin’s sweatpants fell to his ankles.
Eren’s fingers tucked into the waistband of Armin’s boxers. He tugged again, slowly. His smirk grew into a toothy grin as he watched Armin. His half-lidded eyes were glued to Eren’s little performance. His nose and cheeks had become flushed and his chest rose and fell with frustrated huffs of air.
“Am I taking too long?” Eren hummed as he palmed Armin’s erection through the fabric of his boxers. Armin responded with a pouty grumble, his head tilting to the side and his hips bucking into Eren’s hand. “If you take any longer it’ll put me to sleep.”
“It’s called building tension.” With a swift pull, Armin’s boxers met the floor along with his sweatpants. “Spit.” Eren commanded as his hand hovered underneath Armin’s chin.
Armin’s lips curled into a smile as his head leaned down. His hand grasped hold of Eren’s wrist as he dragged his tongue across his rough palm, the metal ball from his piercing bumped over Eren’s rings as he licked every finger.
Eren took his hand back and rolled it over the pink tip of Armin’s cock. The sticky precum mixed with Eren’s saliva laced hand. He dragged the mixed substances up and down as he stroked Armin’s erection.
Tense huffs turned into dragged out breaths of pleasure, Armin’s hips rolling in relaxed circles. “Faster.” Armin requested in a soft moan.
“Nuh uh, I’m not taking demands today.” Eren denied as his hand rose from the base of Armin’s cock to twist around the rest of his length.
Eren’s free hand ran through his hair, moving the long brown locks out of his face and tucking a couple pieces behind his ear. His eyes fixated on Armin’s cock, and a strange sense of hesitation that Armin had never seen before.
After wetting his lip, Armin watched as Eren took a slow approach towards his cock. His head tilted to a better angle as his lips parted and took Armin’s tip into his mouth.
Armin’s hips jerked at the cold sensation of the metal ball exploring the creases and crevices. Eren’s mouth circled and sucked on the tip of Armin’s cock until his head began to lower, taking Armin deeper into his mouth.
Consistent moans began to pour from Armin’s mouth as Eren’s head started to bob up and down. His mouth couldn’t take the full length, but his pace stayed quick and steady.
Armin’s hands reached down to brush away Eren’s hair that had curtained around his face. His fingers twirled Eren’s hair into a makeshift ponytail, holding it in place so he could see Eren. His eyes seemed focused and his brows knitted.
With a sudden surge of dominance, Armin forced Eren’s head down, pushing his cock fully into his throat and his face buried in his crotch.
Eren’s hands gripped onto the flesh of Armin’s thighs for support and his voice winced into Armin’s cock.
A maliciously satisfied giggle rang from Armin as his grip tightened. His teeth bit into his bottom lip as he used Eren’s hair to puppet head, pulling and pushing his mouth up and down to his desired speed.
Sharp breaths of air sucked through Eren’s nose as he let his head be used. His eyes pricked with wet tears as his air continued to be restricted. He whined a high pitched moan each time Armin’s cock hit the back of his throat.
Armin’s grip became weaker and his thighs shivered as he reached closer to his climax. Eren took advantage of the little control he had to swirl his tongue around Armin’s throbbing cock.
Armin held Eren’s head down as thick shots of cum filled his mouth. Shaky pale hands releasing Eren’s hair and traveling down to caress his face.
Eren’s head pulled back, cum sat on his tongue as he picked himself up. His hand reached to grab Armin’s jaw, squeezing to open his mouth. Eren’s lips parted open and his tongue hung out as he spit the cum and saliva mix into Armin’s mouth, who received it with a deep swallow.
“There...” Eren began as he finally started to catch his breath. “You took one of my firsts.”
Armin wiped away a dribble of saliva from the corner of his lips. “Is that what this was for?” Armin grinned.
“I took your virginity now you took my oral virginity.” Eren took more huffs of air as he put his hair back into its low bun. “Now we’re even.”
“Even enough.” Armin pulled his pants back up and ran his fingers through his hair. “Are you going to bed?” Armin questioned as Eren started out of the living room.
“Yeah, your bed so you can return the favor.” Eren called back as he turned the corner into Armin’s room.
—————————————————————————————————————
It’s been about a month and a half since Armin and Eren first had sex. Since that night, the two have had sex approximately 29 more times.
And for another morning, Armin is waking up in bed alone. The blaring sun attacks his awaking eyes and his aching body stays stuck against his sheets.
Armin’s hand pats at the empty spot next to him, the mattress still indented with Eren’s body. It pisses Armin off how, despite knowing he wouldn’t be there, every morning he still checks to see if Eren stayed.
He wants to feel upset, but it isn’t fair to be upset when he brought this onto himself. That night that kicked this all off, not the night of the party, but the night where Armin strolled into Eren’s room and agreed to this relationship of empty sex and ambiguous feelings—it’s a regret that Armin felt the moment he stepped through the doorway.
Armin knows why he agreed to it. For as long as he’s known Eren there’s been this stupidity Armin carries for him, a stupidity that tells Armin he’s a better person than he leads on to be. And now, for another time, Armin is left with unfulfilled expectations.
A painful groan rumbles from Armin as he finally picks himself out of bed. His shirt—well, Eren’s shirt—drapes over his body, covering the small pajama shorts Eren gave him last night.
He took his glasses from the nightstand, pushing them onto his face as he shuffled out of his room into the kitchen for a hangover concoction.
“Morning.” Eren greeted from the corner of the kitchen, already sipping on a mug of coffee. “Did you sleep good?”
Armin shot a bitter side eye as he continued to silently shuffle to the coffee maker. “Fine, I guess.” He muttered, seeing the hot mug of coffee sitting on the counter, already made for him.
Armin’s hand gripped onto the handle. His favorite mug, his favorite brand, made just the way he likes. The first time Eren made coffee after a night of drunken sex Armin thought it was sweet, he thought it was a sign of progress towards something more. Now it feels like a mockery.
“Why don’t you ever stay in bed with me?” Armin turned over to face Eren, awaiting an answer that would attempt to avoid the subject.
“What are you talking about? I always stay in bed with you.” Eren took his eyes off his phone and raised his mug to his lips.
“Yeah but—you stay in there right after we’re done to clean up, you put me in your clothes, and we fall asleep together but once I wake up you’re gone. Even if I’m in your bed when I wake up you’re just gone.” Armin sighed, his spoon slowly stirring the coffee.
Eren put the mug down as he let out a small chuckle. “I don’t know… I guess it feels too romantic to wake up next to each other.”
Armin couldn’t help but scoff. “Before all this we were sleeping in the same bed all the time. When we were kids we were having sleepovers like every weekend and when we moved in together we would still sleep in each other’s beds from time to time. It wasn’t romantic then.”
“Yeah, because we weren’t having sex and then waking up next to each other.” Eren argued. “There’s a difference.”
“Ohh, now there’s a difference? What happened to ‘Why does there have to be a difference, Armin? I don’t want anything to change, Armin.’ Do you see the hypocrisy?”
Armin’s mocking of Eren’s voice was responded with offended scoffs as Eren put his phone down, putting his full focus on the conversation. “I don’t stay in bed with you because I don’t want you to think that the sex is more than what it is. It’s not the type of sex where we wake up next to each other, it’s the type of sex where we just do it and move on.” Eren shrugged as if what he said was only a matter of a fact.
Armin could feel a piece of his heart sink into his stomach. He couldn’t be upset, he signed himself up for this. Relying on an unpromised, unattainable expectation put him right in the spot he deserved to be. A spot that reflected back to him his own stupidity.
“That’s so fucked up… Why do you have to be such a dick?” Armin spat his words at Eren.
“I don’t know… Why do you have to nag at me so much?” Eren spat back, bringing the mug back up to his lips. “It’s 10 o’clock, you should be getting ready for class.”
“Fuck you.” Armin scoffed an absurd laugh. “I don’t know why I waste my time with you.” Armin dropped the full mug of coffee down the sink drain, shaking his head as he stormed out of the kitchen back into his room.
—————————————————————————————————————
Arguments like the one from that morning aren’t rare, Armin thought as he sat in the back of his geography class. Arguments between Eren and Armin have never been rare, they’ve been bickering since the day they met. But arguments, just like everything else, have felt different.
Every time Eren shuts him down it puts a physical pain in Armin’s chest. The empty hole only grows larger with each fight, each ‘what are we?’ conversation leaves Armin feeling even dumber than the last one. But every time, with a cocky smile and a touch to his waist, all his wrongdoings are forgotten.
Something about this time just happened to crack Armin.
Armin’s consciousness returned to Earth as he realized the class had been dismissed. He scrambled to grab all his stuff, hoping his absent minded notes would make enough sense in the future.
As he walked around campus, avoiding going back home between his classes, Armin came to the conclusion that he needed a change. For the past month and a half life has been nothing but school, sex, and Eren. Armin needed a break from it all—maybe except the sex part—and he knew where to find it.
The pads of Armin’s thumbs hovered over his phone screen, open on Jean’s contact.
“Hey” Armin sent, the only text message he’s sent in a stream of unread messages from Jean.
It’s clear that pettiness was the driving force that led Armin to pick Jean, nothing would piss Eren off more than him being alone with Jean. But there’s something else, something about Jean that tells Armin he wouldn’t be getting himself into another mess.
“Hey, what’s up?” Jean messaged back before Armin could even exit out of the app.
The quick response made Armin a bit flustered, it’s too late to back out of anything now. “I was thinking of coming to another party tonight. But I want you to show me around this time.”
Jean liked the message, Armin’s lips cracked a small smile. “I’ll be your guide.” Jean responded, punctuating his sentence with a wink emoji. Corny. But cute.
—————————————————————————————————————
It was about 30 minutes until Armin was meant to meet up with Jean at the designated time they chose. Armin stood in front of the mirror as he finished up getting ready in the, thankfully, empty apartment.
His finished trailed his grazed over the trail of hickeys and bite marks that have been fashioned on his body over the past few weeks. Pounds of makeup was usually Armin’s go to when he wanted to hide his shame, but if plans go the way Armin planned, makeup wouldn’t be the best way to go.
“What are you doing?” Eren’s voice called from outside the bathroom door. His sudden presence made Armin jump.
“Don’t sneak up on me like that.” Armin huffed as he adjusted his glasses, turning back to the mirror. His fingers inched down the collar of his shirt as he exposed his bruised skin to his reflection. “I’m looking at how much you ruined me.”
“You look like you’re getting ready. Where are you going?” Eren stepped further, standing in the middle of the doorway.
“I’m going out—out to a party.” He answered as he brushed his fingers through his hair, fixing up the blond locks that framed his face.
“Well I didn’t have plans of going out tonight. And I know you’re not going by yourself. So who are you going with? Mikasa?” Eren’s body leaned against the doorframe as he tried too hard to act casually.
“Eh, wrong. I’m going with Jean.” Armin struggled to hold back his smile of revenge.
“You’re joking again right?” Eren’s voice was low, suddenly serious.
“No, I’m serious. We’re supposed to be meeting up in like 20 minutes so I should actually go.” Armin started out the bathroom, being stopped by Eren’s arm as it looped around his waist.
“Why the fuck would you want to go to a party with Jean?” Eren turned his face up, still holding Armin away from the door.
“I had an epiphany this morning that told me I should start being more logical with the men I sleep with.” Armin snarked.
“And Jean was the next best person?” Eren scoffed a chuckle.
“Eren, get out my way. I really don’t feel like talking to you right now.” Armin’s eyes rolled away from Eren as he attempted to step past the door again.
“Wait, okay I get it, I was being a dick this morning.” Eren caught Armin again before he could leave. “I’m sorry, lesson learned.” Eren softened. Of course this is when he softens.
“Don’t apologize.” Armin stopped in Eren’s arms, his hands raised up to rest on his shoulders. “You were right, you’ve been telling me since the beginning that it’s just sex—and it is. But… I realized that I’m just too mature for that bullshit.”
A second arm wrapped around Armin. “So, I think it’s best if we just stop. You should go find one of your little groupies to have stupid, meaningless sex with because I’m honestly over it. We can just go back to normal. Forget that whatever happened even happened.”
Armin breathed a heavy sigh. Something about this moment felt less gratifying than it was supposed to. That look on Eren’s face, it ruined the satisfying break off that this was supposed to be.
“Don’t say that.” The genuinity in his voice, the gentleness of his touch. “You smell good. Stay with me tonight.”
It was all fake. Maybe a couple months ago—hell maybe even a week ago, it would have felt real. Armin would have sank into his arms and believed every word. But now all Armin could do is study Eren’s face and try to figure out how long he’s been falling for it.
“…I have to go.” Armin’s voice cracked in a whisper as he pulled out of Eren’s grip.
Leaving Eren’s touch felt just as wrong as stepping into it. Armin’s chest felt heavy as he left the bathroom to gather the rest of his stuff. It seems that no matter what decision he makes, any decision concerning Eren will produce a cloud of regret that looms over Armin. Longing for an answer that will never come to him, Armin leaves the apartment.
Another night of alcohol, weed, and sex will get his mind off of it.
