Notes: Soooooo this came from a prompt from tumblr. Basically, this will be a collection of sides/smutty oneshots set in the SoT-verse that are not ereri-centric :3 But they'll still be semi-relative. Hope y'all enjoy!

It wasn't every day that Bertholdt stopped what he was doing to really stare at Reiner. But it was a Tuesday and that meant it was an early workout day. And an early workout meant that Reiner was home early and it was rather distracting.

Not that ordering textbooks or setting songs up in a playlist were difficult tasks, but having an attractive boyfriend made it hard to multitask. Especially when Reiner was walking around in just a low-hanging towel searching through the drawers for something to wear.

Bertholdt neglected his book purchase and tugged his earbuds from his ears, slowly closing his laptop.

"C-Clothes are optional," Bertholdt muttered, his cheeks turning as red as the boxers Reiner had fished out.

Reiner turned, eyebrows raised and a grin on his face. "What was that?"

Bertholdt's eyes widened and he shrunk back behind his laptop, giving a little shrug. He tried to zoned back in on his books but Reiner was moving across the room, hands on his broad hips. Bertholdt curled his toes nervously.

With a gentle hand, Reiner tugged the laptop from Bertholdt and set it on the nightstand. "Bert."

"Y-Yeah…?"

The towel was getting loose, barely hanging around Reiner's waist and demanding Bertholdt's attention. But so were Reiner's arms and his stomach and his eyes and lips.

Bertholdt reached forward, cupping his face, and pulled Reiner close, kissing him lightly. Reiner pushed him back against the bed and Bertholdt gasped, biting at Reiner's lip and dragging his nails down his boyfriend's arms. He left bright red marks against his shower soft skin.

"Something about clothes being optional?" Reiner pushed.

Bertholdt pulled away to cover his face with his hands, unable to look Reiner in the eyes. "I just meant that…you know…the view is…nice..."

Reiner took his hands and kissed him on the cheek. "Don't explain. Let's just have optional clothing."

He said it as he tugged off Bertholdt's shirt, letting it fall to the side of the bed. Bertholdt was relieved to be free from the heated thing. He let out a sigh as Reiner kissed along his neck and collarbone. He threaded his hand through Reiner's short hair, holding him close and feeling his chest against his skin. Feeling Reiner's breath against his neck and how his chest moved and how his hips pushed forward.

Bertholdt sighed, biting his lip as Reiner pulled at his shorts, tugging them off. Bertholdt kicked off his shorts and Reiner tossed away his towel, his cock proudly springing forward. Reiner reached for the blanket at the end of the bed and pulled it over them, covering Bertholdt up. And Bertholdt smiled, snaking his long legs around Reiner's waist to tug him closer.

Biting his lip, Reiner pushed his cock against Bertholdt's and listened to the muffled moan he made at the contact. Reiner took his time rolling his hips and sucking along Bertholdt's neck. Bertholdt trembled under him, grabbing at Reiner's arms and pushing his own hips forward until his moans turned to whimpers.

Reiner blindly reached over on to the nightstand, fumbling around until he found the bottle of lube. He sat back and Bertholdt groaned in protest, quickly covering his mouth as the soft noise escaped. Bertholdt grabbed at the blanket as Reiner popped the bottle open, covering himself up with a shy flush over his cheeks. Reiner smiled.

"Why do you always cover up?"

"I just…I—" Bertholdt was flustered and timid all at once, his words running together. Reiner slipped a hand between Bertholdt's legs, leaning over him as he quickly found his entrance. "I'm just so lanky and—" He lost his thoughts at the feel of Reiner's slicked up fingers.

"Literally perfect," Reiner said as he nipped Bertholdt's ear, fingering him slowly. Bertholdt threw his arms around Reiner's neck and didn't bother to try and hide his moans. He didn't stop Reiner from pulling the blanket away from his chest. He lost himself in Reiner's scent and his heavy breathing and his deft fingers and sweet words.

Reiner shifted, back between Bertholdt's legs, and pushed the head of his cock through that tight ring of muscle. Bertholdt curled his toes and pushed his hips forward, making Reiner slide deeper inside. He was used to the girth and the initial little pain. They had been together plenty of times and for years (since high school). So even after that quick pain, Bertholdt knew the sweetest pleasures were going to follow; he knew Reiner would take care of him.

And he did. Reiner kissed Bertholdt softly before moving, sliding his hips in and out, grabbing Bertholdt's hair. Bertholdt let out a silent gasp, digging his nails into Reiner's back until fresh red lines were drawn across his skin.

With a snap of his hips, Reiner hit that sweetspot and Bertholdt jumped, hugging him closer. Reiner hit that spot again, this time with purpose, over and over until tears streaked Bertholdt's face as he came. White splattered onto their slapping stomachs, and Reiner gasped, cumming harder while he was still buried in Bertholdt.

The two of them caught their breath, staring intently at the other. Bertholdt's lips quivered and Reiner caught them between his teeth in a gentle bite.

Reiner smiled. "I need to go shower again."

"I-I should join you…"

"I think you should, too," Reiner said, punctuating his comment with a kiss to Bertholdt's hand. "And when we're done, you should sit on my face for a while."

"I'm too tall!"

"We'll make it work," Reiner teased, running hand through dark hair. He sat up and stretched and Bertholdt grabbed his arm.

"It…it m-makes no sense for us to shower and then…you know again," he said quietly. "We should…just…do it now."

For once, Reiner flushed with wide eyes. "Oh?"

Bertholdt nodded, hiding his red face in his hands. "Just a suggestion."

"I think I like your suggestions a lot."

A smile crept onto Bertholdt's face and he pulled Reiner in close for another kiss. This one chaste and gentle, still a little shy. And Reiner returned the kiss with a gentle hand to Bertholdt's face, letting his fingers trace dark hair and down to the line of his jaw.

"I have…another…suggestion," Bertholdt said. Reiner raised his eyebrows.

"Yeah?"

"Umm…well…what if…we…What if we were more than just…boyfriends?"

Reiner sat back, pulling the blanket over Bertholdt's lap and tucking him in. "What do you, Bert?"

"What if…What if we were the first of our friends to settle down…?"

"As in we have a little ceremony? With a cake and a preacher? Or a courthouse, whichever you want?"

Bertholdt nodded and Reiner took his hand. "With rings and vows."

Reiner smiled and snaked his arms around Bertholdt's shoulders, holding him close as he nodded. "Absolutely yes."
