…

Armin giggled as he stumbled through his front door, throwing numerous gifts and bags on the floor. He was proud of himself, he managed to get through an entire night of drinking with his friends without needing someone to drag him back home.

That role would usually go to Eren, who was also floundering through the entryway. Both men were giggling, slightly leaning on each other while they managed to find their way to the living room.

“Fuck, man.” Eren wiped his hands down his face, following Armin’s lead and kicked his shoes off. “Our neighbors must think we’re crazy.”

“You were the one fake moaning right outside their doors!” 

“Trust me, Min. That was not fake.” Armin snickered as Eren walked forward, his hands reached out. “You look so good.”

He could only laugh when Eren grabbed his shoulders, hands running down his arms. Eren was attempting to feel him up, and honestly Armin couldn’t blame him. He purposely wore this sweater tonight because of how soft it was.

Eren pulled him closer, and Armin continued to laugh as he looked up. “You like it?”

“Don’t play dumb.” Eren had no shame in reaching around, giving Armin’s ass a tight squeeze. “You know I love these pants.”

“I guess I’ll have to keep them on all night!”

Eren chuckled, shaking his head. “I can’t fuck you if you have pants on.”

“Whatever shall we do?”

Eren bursted out laughing, and Armin followed suit. Their bodies pressed against each other, and despite the chilly weather Armin has never felt warmer. His sweater was putting distance between him and Eren’s button up, which Armin would like to add looked very nice, and all he wanted to do was rip their clothes off and do something.

“Did you have a good birthday?” Eren reached up and pushed Armin’s bangs away from his forehead, letting his hand run through the blond’s hair. “You looked like you did. You handled the shots pretty well.”

“Sasha has nothing on me.” Armin smiled and closed his eyes, leaning into Eren’s touches. “Did you see what she got me?”

When Eren shook his head, Armin snickered while pulling away. He walked towards the group of bags on the ground, picking up the green one before handing it to Eren. The man grinned before taking it, reaching inside while Armin walked away. When he felt metal he paused, before digging in with more urgency.

He pulled out a pair of handcuffs. He stared at them for a moment, his brain processing what handcuffs meant. He picked his head up to glance at Armin, but turned around when he realized the blond was standing near their bedroom door.

Armin leaned his head against the wall, hooded eyes meeting Eren’s. “What do you think?” 

“Look at you, birthday boy.” Eren swung the handcuffs around, shifting his weight. “You thinkin’ what I’m thinkin’?”

Armin didn’t verbally respond, and it’s not like Eren needed him to. Armin gave him the look, and despite the alcohol running through his veins, Eren immediately knew what was coming next. 

“Get on the bed.”

Armin smiled, and Eren followed him as he ran into the bedroom. He did what he was told, and managed to crawl onto the mattress without immediately passing out. The bed has never been softer, his body has never felt warmer, and it’s been so long since he’s felt this happy. He definitely had to send Sasha a thank you card sometime soon.

Eren was half on the bed when he reached down towards Armin. He pulled their bodies closer, meeting Armin’s lips with his own. He couldn’t hold back a snicker when Armin made a subtle but noticeable noise, and carefully put all his weight on the mattress.

He continued to kiss Armin, slowly pushing the both of them down until Armin’s head hit the pillow. Their bodies were once again pressed against each other, and Eren smiled against Armin’s lips when he felt something poke his stomach.

“Already hard?”

Armin breathed heavily when Eren kissed his cheek, his jaw, and then his ear. “N-not fair. You’re wearing that shirt.”

He let out a hum when Eren grinded down on his erection. “How do you think I felt all night?”

Eren’s breath was hot against his ear, and Armin blamed his intoxicated state when he shamelessly grinded upwards into Eren’s hold. Eren was still holding the handcuffs, but used his free hand to cup Armin’s face.

“I’m gonna put them on now, the handcuffs.” Eren met Armin’s eyes. “You’re gonna look so fucking hot.”

Armin swallowed as Eren gently grabbed his hands. He watched as Eren figured out how to open and close the handcuffs, and wasted no time putting each metal ring onto his wrists. He glanced down, grinning when the cold metal met his heated skin. He felt giddy all over, realizing how much he was going to enjoy his night.

Once he finished putting them on, Eren slowly lifted Armin’s hands over his head. He looked back at Armin, smiling at the position he put the blond in.

“God, you’re gorgeous.”

Armin blushed, his legs closing together. “How? My clothes are still on.”

“Don’t worry, I’ll handle that.” Eren leaned down, and went back to attacking Armin’s ear. “It’s your birthday, remember? Sit back and relax.”

Eren gave Armin’s ear one last kiss. He slowly, too slowly, moved his hands down Armin’s sides and under his sweater. Eren slowly lifted it up, pushing the soft material until it pooled around Armin’s wrists. Eren snickered, looking down and eyeing Armin’s body.

“Since when do you wear undershirts?” Eren gently reached down, rubbing his fingers over the white cotton and meeting Armin’s nipples. “It’s so thin, I can see right through it.”

Armin’s face went bright red, and he turned his head to the side as Eren gently rubbed and pinched at him. They never did much nipple play, but right now Armin had to hold back the high pitched noises attempting to escape his throat. He couldn’t hold himself back from wiggling around, trying to create friction for his erection while simultaneously reacting to Eren’s attacks.

“You’re so soft.” Eren positioned himself in between Armin’s legs, continuing to squeeze the small buds between his fingers. “Such a good boy.”

Armin couldn’t hold back the whimper that left his mouth. After a few moments, he let out a sigh when Eren let go of his nipples. He did the same to the undershirt as he did to the sweater, pooling the material around the handcuffs until as much of Armin’s abdomen was showing. Eren bent down, kissing and nipping at the exposed skin.

Armin gasped when Eren’s hand suddenly met his clothed erection. On instinct his legs attempted to close themselves together, but Eren was blocking them from doing so. Eren was smiling, watching Armin’s reaction as he palmed the man’s front.

“You’re such a little mess.” Armin was whimpering, and Eren ran his free hand down the blond’s thigh while he listened. “Don’t hold back, okay? Be good and show me how loud you can be.”

Armin was half listening to Eren’s demands. His head was fuzzy from pleasure, and this time he didn’t stop him from moaning when Eren started palming him again. There was a moment where he attempted to reach down and touch Eren, but the handcuffs held him back.

“Y-you’re clothes.”

“Hm?” Eren started unzipping Armin’s zipper, putting his hands under the hem of both his jeans and his boxers. “My clothes?”

Before Armin could speak, Eren was pulling his pants and underwear down. Cold air hit his skin, and he blushed when his erection sprung out of its cotton restraints. Eren pulled his clothes past his ankles, and Armin heard them hit the floor the same time Eren came back into view.

“Please.” Armin closed his eyes, not able to handle watching Eren’s body press against his own. “Your shirt.”

“What about my shirt?” Eren reached up, and Armin’s eyes opened as quickly as they shut. Eren was grabbing his chin, forcing eye contact. “Use your words.”

“… take them off. Your clothes.”

“Good boy.” Eren smiled, pulling Armin forward and pecking his lips. “Only cause it’s your birthday.”

Armin couldn’t hold back a grin from both the praise and the joke; as if Eren was planning on keeping his pants on all night. He watched Eren unbutton his shirt, tossing it haphazardly on the ground. He did the same for his pants, and soon both men were completely naked on top of their bed. Armin wiggled a bit, and Eren grabbed both of his knees to keep him in place.

“Do not move. I need to get the lube.”

Armin nodded, his heart pounding against his chest. He tried to calm himself down from how windy he felt, and focused on Eren moving around the room. He shifted as little as possible, even managing to keep his legs separated while they stayed right where Eren positioned them. A part of him wishes he had prepped himself beforehand, but in his defense he had no idea he’d receive handcuffs as a birthday present.

He also had no idea that Eren would like them so much.

“Alright.” Eren slowly made his way back onto the bed, carefully opening the lube bottle. “Two fingers, yeah?”

Armin nodded, shifting his lower half to line himself up with Eren’s body. Eren lubed his fingers up, putting the bottle down before turning back to face Armin. He moved his fingers lower, closer to Armin’s hole.

“Ready?”

When Eren received a nod, he gently pushed two fingers in. He heard Armin gasp, and eventually hum once Eren’s fingers were fully inside. Armin felt tight, but luckily it didn’t hurt as he moved around. Erne used his other hand to push Armin’s knee forward, making it so his leg was slightly raised in the air.

Armin let out a proper moan when Eren started to separate his fingers, stretching out his hole. He turned his head so his cheek was against his pillow, and closed his eyes as Eren began pulling his digits in and out. His face felt flushed and sweaty, his bangs sticking to his forehead. Eren had gotten very good at stretching him out, and Armin had to control himself from cumming at the act alone.

“Feels good?” Armin hummed at the question, gasping when Eren lifted his leg higher in the air. “You’re taking it so well, Min.”

Eren leaned himself forward, pushing his hand deepening into Armin. The blond’s breath hitched when Eren’s mouth was back at his ear, his voice in a hushed whisper.

“I’m gonna fuck your brains out.”

Armin’s eyes watered when Eren pulled his fingers out. He felt a little empty, but one glance at Eren’s erection wiped that feeling away. He cursed Eren for not only being blessed in the size department, but also for the fact that Eren knew exactly how to use it to his advantage. 

Eren wasted no time leaning down, lining himself up with Armin’s hole. He gently guided himself into Armin, taking his time. Once his tip went past the ring, Eren let out a groan. He put both of his hands on the mattress below him, using his hips to push forward. Eren hung his head low, listening to Armin’s gasps and grunts as he pushed himself inside. Once he was in as deep as he could go, he looked up at Armin.

The blond’s face was pink and shiny, and Eren felt like he could cum at Armin’s facial expression alone. Armin’s eyes were fluttering and his mouth was open just enough to allow him to pant, and Eren couldn’t help but stare at his lips. He bent down, capturing Armin’s mouth for a deep kiss.

Eventually, he pulled back. “You’re pretty, did you know that?”

Armin mustered enough energy to look up and meet Eren’s eyes. The man was balls deep inside him, kissing him and calling him pretty. Armin didn’t know if he was about to cum, cry or both. Eren made him feel like putty, weak and flustered just from his gaze alone. He felt like Eren’s eyes were piercing into his own, and that alone made him submit to Eren’s desires.

“Y-you, I…”

Eren snickered. “It’s okay. Maybe this’ll help.”

Armin’s eyes widened when Eren pulled himself out. His shock left as soon as it came, as Eren quickly thrusted right back into him. Armin blamed the alcohol for the moan he produced, his head whipping back against his pillow. Eren continued thrusting in and out, slamming their bodies together without a care in the world.

Eren hit a particularly good spot, and Armin blushed as he moaned in pleasure. “Eren!”

The man continued thrusting at that pace, the sound of Armin’s noises only motivating him to go faster. He was grabbing at Armin’s thighs now, helping him push in and out and angling Armin’s body. His cock was wrapped in warmth and wetness, and Eren couldn’t hold back his own moans and groans as he pushed himself impossibly deeper.

“Fuck, Min…” Eren closed his eyes, his fingernails digging into Armin’s skin. “Feels so good. You’re so good.”

Despite the creaking of the bed and his own volume, Armin whimpered at the praise. Both his legs were in the air now, letting his body fully relax and be at display for Eren’s enjoyment. His erection, despite being untouched, bounced around and felt ready to burst.

“Eren, I-I’m close.”

“M-me too, fuck.” Eren picked his head up, slowing his pace. “Not yet, Min.”

Armin furrowed his eyebrows when Eren’s thrust became slower. He managed to give Eren a glance, watching as the man put his hands back on his knees.

“Think you can go on your stomach?”

Armin blushed at the question, but nonetheless nodded at the request. Whatever it took to get him and Eren off, he was more than willing to do.

“Good, Min.” Eren reluctantly pulled himself out, watching as Armin silently flipped himself over. “You’re such a good boy.”

Armin whimpered, burying his head in his arms. The handcuffs surprisingly didn’t get in the way, as Armin was still able to hold himself up by his elbows. He did, however, feel embarrassed as he stuck his ass up in the air. He could feel Eren grabbing his hips again, and closed his eyes to relax himself from displaying himself in such a way.

His breath hitched when Eren pushed himself back in, his bottom stinging at the sudden intrusion. Eren began pushing in and out, eventually catching up to his original pace. Armin put his head down and groaned into the mattress, attempting to dull the noises he was making.

He was surprised at how attentive Eren was. The man saw what he was doing, and despite his powerful thrusts, he was able to reach his hand around and put it gently into Armin’s hair.

“Didn’t I tell you not to hold back?” Armin whimpered, nodding into Eren’s hand. “Thought so.”

Eren’s hand suddenly gripped his hair. Armin’s eyes slammed shut when Eren unexpectedly pulled his head up by his hold, craning his neck backwards. He let out a high pitched scream, louder than he meant to be. Eren heard the noise, and to Armin’s surprise slowed his thrusting pace and loosened his grip.

Eren hesitated, watching Armin closely. “Color?”

Armin painted, contemplating before pushing his head back up into Eren’s hand. “G-green.”

Eren tightened his grip again. “Good boy.”

Armin felt Eren thrust himself back in, and this time Armin let out a wet and solid moan. Eren pulled his hair back again, his hold strong and firm. Armin’s head started to feel foggy, and saliva started to escape his lips as his mouth hung open. He moaned and groaned with every thrust, and he let himself get lost in the feeling in his head.

Pure pleasure filled his entire body. All he could feel was Eren’s hand in his hair and his cock filling him up. Despite how his neck hurt and how sore his bottom felt, Armin felt like he could be in this position for hours.

“Fuck, Min…gonna cum.”

“Me t-too.”

Armin’s hands gripped the sheets beneath him. Eren’s hold on his hair loosened as he came close to finishing, and Armin took it as an opportunity to lean back onto his elbows. Eren’s pace quickened, and Armin’s eyes fluttered as Eren started to hit his prostate.

After a few more thrusts, Armin let out a particularly high pitched moan. He came onto the mattress sheets, arching his back in pleasure. He could still feel Eren thrusting in and out, and his mind started to go white from the overstimulation. 

Soon after, Eren let out a deep groan. Armin felt himself get filled up with cum, and gasped into the bed beneath him. Eren brought both hands to Armin’s hips, significantly slowing his pace down to ride out his high. He let out a shaky breath, eventually stopping his thrust altogether.

Eren tapped his hip. “Can I pull out?”

“Y-yeah.” 

Armin was surprised he could still verbally respond. His breath hitched when he felt Eren slowly pull himself out, suddenly feeling empty. Armin let his hips fall onto the mattress, breathing heavily while laying on his side. He could feel the bed dip, and kept his eyes shut while Eren moved around him.

After getting the handcuffs taken off and hearing them be put on the floor, Armin felt Eren’s warm hand on his shoulder. “Feeling okay?”

Armin only hummed in response. His body felt exhausted and his throat was tired from making so much noise. He leaned into Eren’s hand, managing to open his mouth. “You?”

“That was incredible, Armin. You were so good.” Eren sounded out of breath, and Armin guessed that the man ran a hand through his hair to get rid of the pieces stuck to his forehead. No doubt he was just as sweaty as Eren was.

“How’s your head feeling?”

“...foggy.”

“Good foggy or bad foggy?”

“Good foggy.” Armin forced himself to open his eyes, turning his head to meet Eren’s gaze. “Very good foggy.”

Eren smiled. “Good. Come with me to shower, okay?”

Armin nodded, and let Eren gently grab his forearms. He let himself get helped into a sitting position, groaning when his weight was put directly on his bottom. Eren gave him a look of sympathy, standing up to put himself in front of Armin. He attempted to get Armin up, but realized the blond needed a moment or two.

It took him a little bit of time, but he’s gotten used to how Armin behaves after sex, especially rough sex. He wasn’t sure if it was ‘subspace’ per say, but it took Armin a while to bounce back to his usual self. Eren would argue it was beyond just ‘feeling tired’; at times Armin acted like a pile of mush, and didn’t respond other than the occasional nod or shake of the head. That’s why Eren would choose to word his questions as statements, at least for essential things like showering. It’s not that he wanted to tell Armin what to do all the time, but Armin would sometimes wind up in a headspace that demanded blunt direction.

He managed to help Armin stand up, smiling when the blond put most of his weight on him. Luckily, Eren liked going to the gym. Even more lucky, Armin stopped growing at the age of seventeen.

After throwing their dirtied sheets in the hamper, he carefully brought Armin to the bathroom, turned on the hot water and grabbed two towels for them. While waiting for the water to warm up, Eren brought his hands up to cup Armin’s face. 

“Promise me you won’t pass out in the shower?” When Armin started to protest, Eren let out a chuckle. “I still need to give you my birthday gift.”

Armin raised an eyebrow, mumbling in response. “...wasn’t all that it?”

“Nope.” Eren brought his hands down, grabbing Armin’s. “Now come on.”

The pair walked into the shower, and Eren went straight to work washing their bodies. He tried to be as gentle as he could be, thankful that Armin stopped feeling embarrassed about the aftercare process. He never understood it, considering he’s seen Armin naked a million times, but Armin used to get so shy whenever they were naked in a not-intimate setting.

After washing their bodies, Eren got the shampoo out. He was about to put it in Armin’s hair when he suddenly stopped. 

“Shit I forgot to ask, is your hair okay?” Eren looked at Armin’s scalp, gently pulling his hair apart. “I know I was a little rough.”

“..’m okay.”

Eren could read him like a book. “It just hurts a little bit? Sore?” When Armin nodded and leaned into his touch, Eren sighed. “I’ll be gentle, don’t worry.”

He carefully massaged the shampoo into Armin’s hair, being even more cautious when using conditioner. He was honestly surprised Armin managed to stand still for so long and not fall asleep, considering how sore and tired he must have felt.

After a few more minutes of showering, with the occasional kiss of course, Eren turned the water off. He quickly wrapped him and Armin in towels, drying off before making their way back to the bedroom. Armin didn’t look too happy about the lack of warmth, however he seemed more associated with his surroundings than before.

When he reached to grab pajamas, Eren put a hand out. “Wait! Don’t.”

“Why not? I’m freezing.”

Eren smiled, walking towards the bed without a word. Armin could only watch as Eren bent down, grabbing a small bag from underneath their bed. He smiled as Eren walked back over to him, holding out the bag.

“Happy birthday!” 

Armin giggled, looking down and opening the bag. He gasped when he saw what was inside, glancing up at Eren before pulling the contents out. Armin was holding a brand new pair of silk pajamas, dark blue and as shiny as could be.

“Eren, I love it!” He wasted no time walking forward, not caring about his sore bottom. “Thank you so much!”

He pulled Eren into a hug, smiling when he could hear Eren chuckle and ‘of course’ before hugging him back. He felt Eren kiss the top of his head and rub his back, slowly pulling them apart.

“Go put them on. I’ll go get water.”

“I’m not thirsty.”

Eren started to walk away regardless. “You say that and then you yell at me the next day for believing you.”

Armin snickered, watching Eren leave the room. He wasted no time dropping his towel and putting the new clothes on. He felt like he could melt on the spot; Eren bought him the best pair of silk pajamas he could find. They were perfect.

He winced as he sat down on the mattress, though he tried his best to ignore the pain. His bottom would hurt for days, he was sure of it. However, he didn’t let that stop him from thinking about future plans. Doggy style would definitely have to become the new norm, and no doubt Eren would be on board with that idea.

Speaking of Eren, the man came back as soon as he left. He put two water bottles on their bedside table, smiling when he saw Armin in his new pajamas.

“Like ‘em?”

Armin quickly nodded, watching as Eren went to put on his own pajamas. “They’re perfect, Eren. Better than my other ones.”

Eren slipped on a pair of sweatpants and an old tshirt, feeling content. He found his way back to the bed, laying down with his arms open. Armin saw the invitation and grinned, slipping into Eren’s arms like the two of them were puzzle pieces. He held back a laugh when he suddenly felt Eren’s hands all over him, rubbing his back and shoulders as they laid. Eren loved it when Armin wore silk pajamas; there was something about the material against his palm and Armin’s skin that made him feel mushy on the inside.

They laid quietly for a few minutes, soaking in each other’s comfort. It was only when Eren heard Armin’s breath become steady that he jossled them up.

“Drink some water before you pass out.”

Armin only grumbled. “..’m tired, n’ comfy.”

“C’mon, baby.”

Armin turned red at the pet name. Eren didn’t call him that often, but when he did Armin knew that it meant it was nearly impossible for him to go against whatever Eren wanted. It’s not like Armin needed a lot of convincing, but it was hard to deny the domestic atmosphere that made him want to comply.

He drank a decent amount of water, more than Eren was expecting him to. He quickly went back to his original position, laying on Eren’s stomach and shoving his face in the crook of Eren’s neck. He felt warm, comfortable and light.

His eyes fluttered shut when Eren gently kissed his forehead, one hand in his hair while the other rubbed up and down his back.

“Happy birthday, Armin.”
