This is a story i wrote recently (and my first one duh), hope you guys like it.

Recruits Barracks, early morning.

Armin woke up with a big yawn. "Guess i could try start training earlier than the rest" thought the slim blonde, "perhaps then i'd "improve my marks". He climbed down the bunk bed carefully, trying not to wake his roommates. When he got to the floor, he casually glanced to the person under his bed.

And he froze.

There was (y/n), the oldest recruit in their room, an 18 years old. Armin had noticed he usually moved a lot when sleeping, and this time wasn't different. He laid on his bed, his almost naked body uncovered all the way to his knees. Armin couldn't help but notice he only had his trunks on, a hand resting on his well toned abs, and... Armin nearly gasped when he looked down and noticed a huge morning wood barely contained by the fabric. Poor blonde felt his heart rushing. He'd been having this awkward thoughts for a while, fantasizing about him and a random male recruit, often whoever he was training with. Eren, Jean, Marco, Reiner and Bertholdt... but nothing had disturbed him more than (y/n). His rude kindness, his confidence, the way he always demanded the greatest effort from his comrades with rough cheering and loud congratulations (mixed with some insults) had made him the main target of Armin's fantasies and dreams, driving the young recruit to quietly masturbate at night.

For what seemed an eternity, Armin stared at the bulge. Then, in a moment of rush not even he thought possible, his right hand reached, trembling, for his roommate throbbing member. The contact almost made him moan in delight, specially when he felt the pulsations in his palm. He slowly rubbed the hard cock, feeling it through the fabric and experimenting an erection himself. Suddenly (y/n) let out a short but loud moan, which made Armin remember where he was. He backed off quickly, putting his clothes on as silently as he could and walkied fast, almost running, to the training camps.

3DMG Training, Midday

(y/n) felt the wind flowing through his (h/c) hair. His eyes searched for a target, quickly finding one. He enjoyed the pull of his gear when he released the gas in his canister, carefully gauging how much he spent. His blades made deep cuts in the target's weak zone. "Come on guys!" he yelled "You're so slow titans could die of old age before you kill them!". He heard some curses and lughter behind him, his adversaries racing to surpass him. While swinging, he aimed for a specially wide tree, before retracting the hooks and using the momentum to give a few steps on the wooden surface and impulse himself with both legs, a technique his supervisors found strange and his mates, awesome. He smiled, at least, until he made it to the other end of the trainging zone.

"THERE YOU ARE, MAGGOT!" yelled commandant Shadis. "SO YOU'VE BEEN DOING YOUR CIRCUS TRICKS AGAIN, HUH!? WELL GUESS WHAT, IT WAS SO MAJESTIC YOU'VE JUST GAINED THE RIGHT TO CLEAN THE STABLES THE WHOLE AFTERNOON!" (y/n)didn't really care. He knew he was one of the top students, he trained harder than anyone, so being forced to clean the stables wasn't such a big deal. Nonetheless, he pretended to look mad when started to walk his way to the buildings.

2 Hours later...

Sweeping the sweat from his eyes, (y/n) began his chores again. It seemed Shadis had chosen a perfect situation for the punishment, since the officer near the stables told him he would have to clean, feed and give water to the horses... just to begin. In that moment, he heard a soft voice calling for him.

"(y/n), are you still here?" said Armin as he looked around the stable. "Oh, there you... are". He tried not to blush, seeing (y/n) had put his jacket and shirt off, as it was a hot day. "I-i-i tho-ahem-thought you could use some help." For a few awkward seconds that seemed eternal, (y/n)'s (e/c) eyes looked at Armin, his right hand resting on his hips, while the other covered his mouth to hide a susprisingly mischievous smile, before he said "OK, help me with the hay a bit". They spent almost half an hour working, before (y/n) walked to a nearby bucket and put his head in the cool water. Armin looked at him wide eyed, darting between his water-leaking hair, to his face, to his body, his crotch and all over again. "Wanna try?" his partner said. Armin snapped to attention. "N-no thanks, i'm not that hot... i mean tired yet" he said, unsure if he had noticed him admiring his body. "What do we do now?"

"Well, i thought we could take a moment to chill out, y'know. It's nice to chat once in a while, without so many people around. Talk about... different things, not always the training and the scores and all that." Said (y/n), sitting besides Armin, water from his head running down his chest and back. Armin gulped slightly.

"And... What do you want to talk about?"

"Hmmm, let's see... why did you rub my dick this morning?"

For a second, Armin thought his heart had stopped. He couldn't believe his own ears. What the f...?

"H-h-eyyyy! What are you... what do you mean, i never did that, i'd never do that, i'm into girls, i swear!" Armin's voice became almosta shriek as he finished his sentence, but before he could start another, (y/n) chuckled, catching him off guard.

"Don't think i didn't notice the way you looked at me back there. Besides, i wake up easily. This morning you woke me up when you got off the bed, i was having a hot dream. And then..." he smiled widely, making Armin gulp again "Someone decided to say hello to my friend down there. Gotta admit, it was hot boy, you managed to make me want more, ha".

Armin looked at his eyes. "So... you're not mad? That's a relief! I..." He couldn't finish. (y/n) had taken his left hand and put it on his lap, right over his crotch.

"Feel it"

"Wh-"

"Do it Armin. Stroke it. Now. I got hard just thinking about it. I'm afraid you MUST help me with this."

(y/n) stood up, stood against a wall and unbuckled his belt. "Get on your knees, Armin. NOW." The blonde needed a few seconds to process what was going on, until he finally knelt in front of him, his blue eyes wide, panting anxiously. (y/n) slowly pulled his pants down, revealing again the bulge that had tempted Armin earlier, and whispered "Your turn".

Armin's hands trembled as he pulled the trunks down. He let out a gasp, when he finally saw the HUGE member rise, hitting him playfully in his cheek. (y/n) grabbed it and gave it a full stroke, then gently caressed Armin's cheek with his cock. The blonde boy used both hands to grab firmly his lover's member -one hand wasn't enough- and lift it a bit, putting it on his face, closing his eyes and letting the smell of cock and sweat fill his nose, driving him crazy. He gave the cock several kisses, all the length to the top, then to the bottom, to the top again, then stuck his tongue out and gave a few licks on the tip, causing (y/n) to moan in pleasure. He opened his mouth and took the first inches in, savoring every milimeter, swirling his tongue around it like a snake, driving it to the back of his throat, then licking it all the way from the bottom to the tip, next sucking his balls while moaning whithout care. He wouldn't mind being heard, the thought excited him as he unbuckled his belt and pulled his member out, masturbating furiously as his head bobbed back and forth, taking more and more of that cock inside his mouth and throat, until (y/n) couldn't take it anymore and only said "Armin, im gonna..."

"CUM!" thought Armin, feeling the cock pulsing and expanding, his lover's semen puring in his throat, pulling out to have him cum in his mouth "Cum more, please, give it to me, gimmegimmegimme..." He could think of nothing else, tasting his man's meat and cum was too much for the boy, shooting his own load on the floor of the stable. When he finally swallowed the last drops, he realized how slutty it sounded in his head, and blushed. (Y/n) looked at him with eyes full of lust, then lifted him withouth effort and kissed him... or more likely raped him with his tongue. Armin was once again defenseless, moaning and stroking his cock again, until they separated, breathing hard.

(y/n) hadn't felt this horny ever. Not even when he fucked some of the girls in the compound... Mina, Sasha, even sweet Krista paled if compared to the revolution Armin had set into his mind, and cock. He knew he could do anything to him, since he saw his reaction to his kiss. He put him on the floor gently and bent him over. It wasn't until he pressed the tip of his cock against Armin's virgin ass that the boy looked back at him, scared.

"Wait a minute (y/n)! You... your cock... it's too big..."

Chuckling, the older cadet stroke the blonde's hair playfully with his left hand, while caressing his anus with his right middle finger, causing him to moan again, then probing him slowly, inserting a finger, then two, three... finally Armin was again under his control. He told him to relax and began inserting his member in his virgin anus, a few inches a time, holding him by the shoulder, hearing him moan and gasp in a mixture of pain and pleasure. He was so fucking TIGHT! So Fucking HOT! His dick just felt like melting when he finally put it all inside, staying still for a few moments, and then began to pull out slowly and carefully. Armin's cute moans made him want to fuck his ass full speed, but he knew better. Leaning on his blonde fucktoy, he gave him playful bites and kisses in his neck and ear, while his thrusts began to accelerate, Armin whining like a bitch in heat, shoving his butt against him everytime he pulled out more and more inches of cock, rocking nonstop, feeling his orgasm building up and ass clenching around his dick, until (y/n) couldn't take it anymore, and pulled Armin next to him, standing and holding the blonde by his thighs, fucking him while their tongues played in each other's mouth, slamming the boy's ass, until his orgasm came and poured shot after shot of cum inside him while Armin rocked his head back, his eyes rolled back and his mouth open in a dumb scream, once again orgasming with his lover. Breathing heavily, (y/n) sat on the floor against a wall, still inside Armin, hugging him tightly. He then pulled out with a "pop", and put Armin on top of some hay, licking the cum off his chest. They kissed and caressed as they dressed once again, savoring each other, sniffing their scent...

Outside of Dining hall, Evening

"Have you seen Armin?" Eren asked Connie.

"Nope, actually, i was gonna ask you that. Wonder where he went..." In that moment, Armin and (y/n) arrived, their hair leaking water. "Hi guys, sorry to keep you waiting, we lost track of time and just got out of the showers."

"And where the hell where you guys?" Eren looked at (y/n) shirt, wet and revealing his body, and quickly looked away.

"Armin helped me in the stables" replied (y/n), putting his hand on Armin's shoulder "Gotta admit, i REALLY needed a hand"

"Or two" mumbled Armin.

"What did you say?" Connie asked.

"Nothingguyslet'sgetsomefood!" chirped Armin, rushing to the dining room. (y/n) had to cover his mouth to avoid laughing, and followed his friends.
