“Dude, I’m being so serious I don’t want to hear a single word about the library,” Eren said with a deep chuckle as he poured Armin a drink.
The semester had just started at Shigashina State University. And to Armin's greatest luck? He just happened to be roommates and lifelong friends with Eren Jaeger himself.
Of course, they go way back. They’ve seen each other through every season of life. Naturally, Eren couldn’t just leave Armin behind.
Even if Eren didn’t live at the fraternity house, he was still a very, very active member.
And what better way to celebrate the start of the semester than with a party?
“Eren, seriously, I’m taking like 17 credits and—“
“Nope! Don’t wanna hear about class. Not tonight anyway.” Eren interrupted as he offered Armin a red solo cup of who-knows-what type of alcohol.
“Dude. Come on, we’re going into junior year, you’ve got to live the college experience a little.” Eren said as the music of the party started to boom loudly around them.
People slowly started to trickle in. Starting to make a dent in the house's stash of alcohol.
Armin winced at the loud noise, gripping his plastic cup tighter as he leaned in, raising his voice over the growing noise.
“Live the experience? Isn’t the experience supposed to be about my Mediterranean sea life research project? Oh, and I have to update that paper about the effect of microplastics on—“
“Dude, you seriously need to get laid.” Eren interrupts bluntly.
Armin winced, choking air as he processed the words that just came out of his best friend's mouth.
“I—I do get laid.” Armin choked out, the pitch in his voice rising as he tried to hide the obvious blush across his pale skin.
His grip on his drink faltered as his palms went sweaty. Armin nervously laughed off the awkwardness as he shifted on his feet.
“I—I’m not a virgin. I’ve..seen pussy before.” Armin stammered out before frantically taking a big swig of his drink.
He grimaced as the alcohol burned his throat. Armin tried to focus on the uncomfortable burning. Somehow, it was better than tolerating Eren's laugh of absurdity.
“Yeah, through a screen!” Eren teased back as he put his arm around his friend. Armin chuckled weakly at the gesture as his eyes adjusted to the dim lighting.
“Seriously, when’s the last time you at least made out with a girl?” Eren asked with genuine curiosity as he took another big swig of his drink.
“Don’t hate me, but… high-school,” Armin confessed before drowning the rest of the burning liquid in his cup.
“That was what… at least three or four years ago?!” Eren shouted over the music as he tossed his cup to the side, turning to grab his friend by the arms.
“Dude, you're like my best friend, and I can’t just sit and watch you waste away in front of an aquarium,” Eren said frantically.
“Just let loose tonight, have a few more drinks, maybe talk it up with some of the people. Not saying you have to be like me, but maybe just talk to someone, alright?” Eren smiled softly before giving his friend an encouraging pat on the back.
“A-alright, I will. I’ll try not to think about my thesis until tomorrow morning.” Armin replied as he took another gulp of his drink. Tasting the last few drops before he tossed the cup aside.
“That’s the spirit. I’ll be around unless I hit it off with that blonde over there…” Eren said his eyes focused on a girl tucked into the crowd a few feet away from the kitchen.
“I’ll scream really loud if I need help,” Armin replied, earning a sharp chuckle from Eren.
Armin let his elbows rest against the counters as his friend disappeared into the crowd. The music was loud, way too loud. The lights are flashing without coordination.
His eye scanned the room to see if he could maybe find someone he knew. That only became harder as more and more people packed in.
It was too hot, too loud, too crowded.
This is exactly why he didn’t do parties.
“Sorry, Eren..” Armin muttered as he pushed through the crowd. Slipping past couples making out without a care in the world. People drinking, laughing, grinding on each other.
He made a straight escape for the side door.
The wind instantly cooled his skin as Armin stepped onto the balcony. The sounds and chatter of the party were left muffled behind the doors.
Armin let out a deep sigh of relief as the fresh air finally filled his lungs.
His eyes widened as he realized quickly he wasn’t alone.
A girl stood looking over the edge. Arms perfectly folded, ankles crossed as the breeze gently brushed against her skin.
Armin couldn’t help but drop his jaw as his eyes raked up and down her figure from head to toe.
You turned around as you heard the sound of the door closing behind you. It was probably another frat guy who you figured you didn’t want to see.
“Arlert?” You questioned as your eyes raked up and down his appearance.
Your jaw dropped as you scanned him from head to toe. His soft blond hair no longer swallowed his face like you remembered.
His hair was cut off his neck, leaving long bangs across the top that melted softly against the porcelain of his skin.
His ocean blue eyes went wide as they met yours. You couldn’t help but notice how he was perfectly shaven, his dress shirt now pressed to perfection.
He wore a casual blue button-up; the pale tone did wonders against his skin. The top few buttons were left undone, giving you a small glimpse of his sharp collarbone.
He wore a casual pair of slacks to match, tied together with a leather belt, and plain white sneakers.
You let out a soft chuckle of disbelief as you tore your gaze from his outfit to glance back into his eyes.
Armin nervously rubbed the back of his neck before he flashed you a soft smile.
In front of him, of all people.
Armin. The nerd from your Environmental Ethics class last semester…
“Since when do you come to parties?” You asked playfully, your eyes raking him up and down.
“I don’t.” Armin shuddered at your gaze, not in a bad way. With a self-deprecating chuckle, he responded.
“I literally have a paper coming up about the effect of microplastics on coral reefs and the living organisms there…I—I really need to get a head start on it.” Armin stuttered.
Your heart warmed as you watched his eyes light up.
Damn, the nerd stuff really was his element.
“Sounds interesting, actually.” You replied. Watching as he subconsciously took a few steps closer.
“Wait…Really? You’re not just saying that?” Armin huffed. His voice grew shaky as he leaned against the balcony right next to you.
The noise of the party seemed to fade away. The wind was soft against your hair as you glanced up into his eyes.
“I mean, I care about the environment too. The last thing I want is to see a coral reef destroyed. That would be pretty shitty.” You replied, nervously adjusting the straps of your top to give you something to focus on besides the fact that Armin definitely grew some muscle over the break.
His biceps flexed as he leaned against the balcony. His button-up shirt strained against his chest.
“Well, Eren told me no sea talk tonight.” He replied.
“Eren? You mean Eren Jaeger?” You replied, heart thumping in your chest.
You swear you’ve seen the two around campus together. It seemed to be quite the unusual pairing.
Eren was known for his charm…and other assets. While Armin seemed to hide in his shadow.
“Yeah, Erens is my roommate. I’ve known him forever.” Armin replied casually.
Your brows contorted as you thought. Brain scattering as you tried to put the pieces together.
“I mean, he’s got quite the reputation…” You mumbled nervously, tearing your gaze away from Armin to glance over your shoulder through the glass door.
“Yeah, I know all about that. I try to stay out of it.” Armin chuckled nervously. His soft eyes couldn’t help but fall on the way you looked in the dim lighting.
You were pretty, really pretty. And on top of that, you didn’t interrupt him. Even during his explanation of microplastics and-
His heart raced. His cheeks flushed, ears burning as he stared at you again.
He couldn’t help but notice the tight top you wore, the way it showed off the soft skin of your waist and stomach.
You didn’t even realize he was checking you out. Through the window, Eren was causing trouble already…the usual, as it seemed.
When you turned back around to face him, Armin was flushing.
“I’m sorry, I wasn’t staring! I promise..well maybe I was just—“
You raised an eyebrow, heart fluttering at his nervous scrambling. Your client helped me lean in closer. Your arms both rested over the edge of the balcony as the metal supported your back.
“You’re just really pretty,” Armin whispered, his voice dropping a soft octave as his eyes flicked up to meet yours.
God, that blue. It would drive any girl crazy, but most couldn’t handle the sea facts that came along with it.
“Thank you…I mean, you’ve got brains and looks. What’s not to love?” you confessed softly. The tension was coiled thick. The breeze seemed to dissipate between you.
Your hands found his waist, hesitant before they gently wrapped around him. His warmth bled through the soft fabric of his shirt. Your fingertips trembled slightly as they brushed against the leather of his belt.
“I mean…I usually don’t talk to pretty girls often. Especially about coral reefs. I’m a little out of my element here.” He confessed, his eyes darkening as he felt your hands slide around his waist.
He didn’t protest, even though his heart was thumping loud enough to cloud his mind.
“Same here. I mean, my friend Sasha dragged me here. I’d rather talk about coral reefs with you than deal with the drunk mess inside.” You whispered, voice breathless as you felt him press up into you.
Warmth spread throughout your body. Heat flooded down your neck from the gesture. Damn, he was seriously starting to turn you on.
“Guess we have more in common than I realized,” Armin whispered softly, his cheeks still flushed as he gently reached down. His hand was moving with a mind of its own as he gently pushed some of your hair behind your ear.
“God, you’ve changed so much over the summer. I remember you being completely different last semester.” You replied as one of your hands slid from his waist to his shoulder. Gently, you pulled him in until his hips were pressed hard against your own.
Armin let a soft moan slip from his soft lips. His eyes went wide as he realized what he’d just done.
“Shit, sorry…I mean—I guess I hope it’s a good change?” Armin whispered as his teeth tugged hard at his bottom lip to stop another desperate moan from escaping.
“A really fucking good change.” You whispered, the tension was so incredibly tight—
Your hands glided from his shoulder to the back of his neck. The small whimper he let slip on you stirred you on more.
His lips were so close. His breath mingling with your own.
So you closed the distance.
Your lips were hesitant as you sought out his own. Gentle, light, just testing the waters.
Armin moaned shamelessly against your mouth as he desperately tried to move with yours. His hands slid to your waist, his soft fingertips trembling as they brushed against the hot skin.
He pulled you in. His body is all hot and desperate as he moved his mouth in synch with yours.
You kissed him harder, just enough to make your heart skip a beat, before pulling away.
The two of you panted for breath as your foreheads rested together. Armin smirked, his chest tight from the kiss.
“Sorry, I hope that was—“
“Kiss me again.” Armin gasped.
“Fuck…” you cursed, tangling your fingertips into his soft blonde hair as you captured his lips again. This time, harder, stronger with more intent.
Armin's mouth was a little clumsy against your own. You laughed softly against his lips, glad he was so adorable like this. The fresh scent of his cologne made your knees nearly buckle.
The kiss deepened as your tongue slid across his bottom lip. Armin’s grip tightened around your waist at the gesture.
His lips gently parted enough to let you slip in. Tongue dancing dangerously as it caressed his own.
Armin whimpered at your warmth. His body was hot as it rutted up into your own.
The metal railing of the balcony dug into your back. But you couldn’t even focus on the pain with Armin's hot mouth on your own.
“I like—never do this..” Armin pulled away to whisper. The corner of his lips tugged up into a smirk as he pressed another needy, wet kiss to your lips.
You smiled softly as he pulled away. Your fingertips mindlessly playing with his perfectly styled hair as heat pooled hotter in your stomach.
“Me either if we’re being completely honest.” You whispered as your fingertips gently brushed the soft blonde locks from blocking his gaze.
“You’re a good kisser.” Armin moaned, confidence bleeding through as he initiated another kiss.
With a gentle moan, you swallowed it, your core pulsing as his hands slid against the skin of your waist.
“Likewise,” you murmured into his mouth, catching a sharp breath before turning your head to kiss him even deeper.
“Fuck…” Armin moaned as the new angle sent a shiver of arousal through his body.
“Don’t curse…it makes me feel things.” You whispered hope against his mouth, voice shaky.
“What kind of things?” Armin muttered as he dragged his lips away from your mouth. He hesitated only for a moment before he started to kiss down your jawline.
You choked on another moan as you felt his soft lips against the sensitive skin of your neck.
With a tight chest, you leaned back, heart beating loud in your ears as Armin found his confidence.
“I don’t know if you can handle what I’m thinking about you right now.” You gasped, mind going to unholy places as his teeth lightly grazed the flesh of your neck.
With a sharp breath, Armin gently sucked on the self skin, eyes softly fluttered shut as he just felt you.
“Shit—“ he gasped as his hips gently pressed against your own.
“It’s okay…” You coaxed softly. Chest heavy as you fought against to grinding back into him.
“I haven’t kissed like this…in a while,” Armin confessed as he shuddered. Hips slowly rolling against your own with a breathless moan.
You moaned in synch at the contact. Armin was already hard beneath the fabric of his pants, pressed up perfectly against your thigh.
“Relax…It feels good.” You gasped as you gave in. His hands gripped the fabric of his shirt tight as you pulled him in by the waist.
“Does it?” He whispered as his lips grazed your neck again. This time, leaving delicate kisses across the marks starting to form.
“Mhm..” you moaned back. Breath heavy as the heat between you only grew.
Armin's soft lips were teasing your neck, his hard cock already pressed up against your body.
And with one more look into those innocent blue eyes…
You had to have him inside you.
“How do you feel about getting a room, Arlert?”
