Reiner continued to eat his bread, watching as his best friend, Bertolt, sat on his own. He was a few tables across from Reiner himself. He grunted, dropping his bread down to the plate, glaring in Bertolts direction.

"What the hell is stuck up your ass?" Jean asked, his cocky remarks as per usual.

"Shut it, Kirstein." Reiner spat. Jean laughed.

"What the hell is your problem?!" Jean added.

"I said, shut it, before I beat your damn ass." Reiner growled, clenching his fists.

"Oh, that's how you speak to your fellow cadets? Hm." Jean replied, smugly. He folded his arms over his chest, a smirk playing across his face.

"Jean, stop." Marco added in a soft tone.

"Why should I huh, freckles?" Jean spoke, glaring at Marco.

"Don't talk to him like that, horse. Marco did nothing wrong and you treat him like that? What was that you were about to say earlier about how I speak to my fellow cadets?" Reiner slammed his fist onto the table, glaring at Jean. Jean huffed. He sighed.

"Sorry, Marco. You too Reiner." Jean apologized, leaning forward and resting his elbows on the table. Marco smiled.

"Don't worry about it, Jean."

"I'm sorry too… I shouldn't take my frustration on you… And, you're not a horse. Look like one though." Reiner apologized, adding the last part with a grin across his face. Jean scowled.

"But anyway, what's your problem? And why isn't Bertolt with you? He's on his own?" Jean asked, genuinely curious, looking over at Bertolt who was sat alone, staring at his food.

"We had a fight." Reiner muttered, looking down at his food too.

"You and Bertl? Damn, I've never even seen you two separated, let alone fight."

"Yeah. Eh. It happens…"

"How come you fought? Physical or vocal? Who won?" Jean was now leaning forward, intrigued by the new information. Marco looked a bit unsure of Jean's actions. He thought of Reiner's feelings, knowing that Reiner must be upset, mad, and more emotions just like that. Jean wasn't as thoughtful as Marco was. He usually only worried about himself and Marco.

"Just an argument. He pissed me off, that's all. Saying stupid shit… He does it a lot. I couldn't be bothered with it, so I voiced my opinion. He didn't want my opinion, he thought it was wrong. So it led to an argument. That's all, Jean."

"Ah. You guys going to be okay? You've been friends since childhood… What's Annie going to say?" Jean's voice had a hint of sympathy to it. Only slightly.

There was silence, and Reiner simply gave a shrug. He sighed and stared at his barely touched food. Marco patted Reiner's back.

"I'm sure you guys will get over it, you've been friends since you were kids. An argument definitely will not break up a friendship, especially when you have been there for each other for so long… You and Annie are all he has, Reiner." Marco said softly, his smile sincere.

"Thanks Marco… I think you're right. We're just pretty mad at each other right now. He's more upset than mad, I think. I said some pretty awful shit." Reiner mumbled.

He looked up to see Bertolt slowly approaching the table Reiner was sat. They locked eyes for a moment. Reiner could see that Bertolt felt bad, he blamed himself. He had next to no self-esteem, and what Reiner had previously said most likely brought it down even lower. Bertolt stopped in his tracks. He looked at his tray and back at Reiner. He turned the other way and put his tray back on his table, his food untouched. He then left the mess hall. Reiner didn't see where he went.

"Maybe you should go and apologize, Reiner." Marco spoke up, bringing Reiner away from his thoughts. Reiner nodded slowly. He walked over to where Bertolt was sat, picking up his untouched bread. He then exited the mess hall, bringing the bread with him.

He searched the dorms, toilets, pretty much everywhere. He sighed and sat down on some steps. He looked up to his left to see Bertolt making his way into the library. He quickly stood up, following. He shouted for Bertolt, but Bertolt had already got inside the building. He followed him inside, walking behind him at a quick pace.

He followed Bertolt to the back of the library and quickly grabbed Bertolt, slamming him into a bookshelf. Bertolt looked alarmed, staring down at Reiner with wide eyes. He looked around, the isle empty. No one went to the back, as all of the good and helpful books were at the front, as they would. All of the boring things were at the back.

"Bertolt, I'm sorry. I didn't mean it, I never would. You're mine, Bertl. My Bertl. I said those things in the heat of the moment, I meant nothing. I'm sorry, Bertl…" Reiner held Bertolt against the bookshelf tightly, hiding face resting on Bertolt's shoulder. Bertolt kept quiet. He was surprised. Reiner looked up at the taller boy, waiting for something to be said.

He finally spoke up after what seemed like forever.
"I'm sorry too, Reiner. I made you mad… I know you say things when you're mad. It's okay. I forgive you."

Reiner smashed his lips against Bertolts lips, kissing him deeply and forcefully. Bertolt was quick to kiss back. Their lips moved in sync. Reiner kept him pinned there, kissing him and pressing his body right up against Bertolts taller one.
Reiner slowly moved his hands from pinning him there and moved down to Bertolt's thighs. He slowly unbuckled the belts on Bert's thighs, moving up and untucking his shirt. Bertolt wrapped his arms around Reiner's neck, pulling him closer and kissing him passionately. He quietly moaned into the kiss.

He leaned into Reiner's hands as they roamed up his shirt, feeling every part of his torso. Reiner's touch drove him crazy. Just one touch was enough to make him tremble. Reiner slowly dragged his nails down Bertolts chest, all the way to his stomach and stopping to unbuckle Bertolt's belt on his pants.

Bertolt unwrapped his arms from Reiner's neck, rushing to unbuckle Reiner's belts that lay across his torso, thighs and the belt on his pants.

"I want you, Bertolt." Reiner mumbled against Bertolts neck lowly, making Bert tremble. He belonged to Reiner. He was all his.

"I'm yours." Bertolt mumbled back, groaning as Reiner's hands slipped down his pants and into his boxers, stroking his hardening member.

Reiner moved his lips to Bertolt's neck, kissing and sucking. He didn't care if he left marks. He wanted everyone to know who Bertolt belonged to. Bertolt leaned his head back, gasping and holding in the moans. Reiner quickly yanked Bertolts pants down, turning Bert to face the bookshelf. He pulled down his own, slamming his hands either side of Bertolts shoulders.

"Do you want me, Bertl?" Reiner whispered seductively into his partners ear.

Bert shivered and nodded, turning his head to the left, looking at Reiner from the side. "Please, Reiner, I need you."

Reiner kissed the back and sides of Bertolts neck, moving Bertolts legs apart and pulling his hips back. He slowly pushed his length inside him, groaning quietly, staying as quiet as possible. Bertolt gasped, moaning quietly at the feeling of being filled by his lover. Reiner moved his hips slowly before speeding up. He was too indulged in the pleasure to let Bertolt adjust. Bertolt winced for a moment before he arched his back, throwing his head back.

"F-Fuck…" Bert gasped, his fingers clawing at the shelf he was against.
Reiner pounded inside his friend, keeping as quiet as he possibly could. Bertolt moaned, louder than he should have. Reiner immediately clamped his hand down over Berts mouth, slamming inside him at a quicker pace. Reiner wouldn't be surprised if his lover's muffled moans were still heard from the front of the library. He didn't care. It felt too good.

"Reiner!" Bert moaned against Reiner's hand, his hands reaching up and grabbing onto the shelf to hold himself up. The pleasure was almost too much. He could barely handle this, he loved every second of it. Reiner reached up with his free hand, tangling his hands in Berts hair, tugging roughly, adding to the pleasure Bertolt was feeling.

"Bertl… Ngh…" Reiner moaned quietly, slowing his thrusts as he felt himself get closer and closer. He didn't want this to end, and neither did Bert.

"Agh…" Bert moaned, his fingernails leaving deep scratches in the wood of the shelf.

The familiar feeling rose in Bert's stomach, his stomach tightening. His legs were beginning to weaken as he felt himself coming undone. Reiner slammed into his prostate and did so perfectly each time. Every thrust hit the spot, intensifying Bertolts upcoming orgasm. His closed eyes tightened, teeth clenching. His moans got more desperate sounding, his breaths heavier.

Reiner panted heavily, his orgasm nearing. He didn't want to stop.
His thrusts became faster, moaning lowly as he felt Bertolt clenching around him.

"R-Reiner! Ah!" Bertolt moaned, unable to keep them in. Luckily they were muffled by Reiner's hand. He moaned his lovers name over and over, cumming hard, his intense orgasm finally reached.

Reiner's followed close behind, gasping Bertolt's name, panting. He leaned into Bertolt, moving his hands to lace his fingers through Berts.

Bertolt panted, squeezing Reiner's fingers. They stayed there for a moment before Reiner pulled out and pulled his pants up. Bertolt did the same, leaning back against the bookshelf.

"That was amazing, Bertl." Reiner whispered softly, leaning up and kissing Bertolt tenderly. Bertolt kissed back. They got fully dressed and stood there, embracing each other.

"My Bertl." Reiner whispered, tracing his fingers gently over the marks he had left all over Bertolt's neck. Bertolt reached his hand up and grabbed Reiner's hand, bringing it up to his lips and placing soft kisses over it.

"Yours."

"Thank god, they've finished. Geez." A familiar voice called.

Their heads swung to where the voice came from, shock all over their faces. Ymir.

"Come on, Krista. Our turn." Ymir pulled Krista into the isle, shooing the two boys away.
