He stared down at Eren, dared him to repeat what he just said.

"Captain, I really think that it would work."

Levi narrowed his eyes. If he was being fair, the offer was perfectly logical and would indeed help their situation. The idea of sleeping with Eren Jaeger was a lot more appealing than the chances of him freezing his balls off.

He took in a deep breath and exhaled through his nose.

"Scoot over."

"Sir?"

"Really, Eren? You're the one who suggested this in the first place," Levi snapped. He started to clamber on top of the bed, fitting himself under the thin sheaths. "Isn't this comfortable."

Long arms hovered over him and Levi snapped his head so fast to look at Eren, the latter almost jumped in place. "What the fuck do you think you're going to do?"

"Trying to keep you warm, sir?"

Levi gritted his teeth. Eren placed his –long ass– arms around him and pulled him closer.

"Is this okay, Captain?"

Levi wanted to yell at the soldier, to point out that he didn't have much of a choice, but Eren's abnormally hot body –both literally and figuratively– was quickly proving to be quite helpful, so he hummed out his response.

"I'm glad I could be useful to you, Captain Levi."

"Eren?"

"Sir?"

"Shut up."

Levi was drifting off, already half asleep. He rolled on his side, facing away from Eren, and subconsciously scooted closer to the warm body.

Eren was so warm, his arms wrapped tightly around Levi, that Levi couldn't help but want to get even closer. He was about to roll again to face the boy, pride be damned, when he felt something poking him.

Well, there goes any trace of sleepiness.

"Eren, I really appreciate your warmth but I don't think I can say the same for your crotch if that's your dick pressing up against me."

Eren really jumped this time. "Shit, shit. Sorry— I thought you were asleep— shit."

Levi turned, facing him, and he almost laughed at the reddening of the boy's face and the comical widening of his eyes. "I don't really appreciate the thought that you think it's okay for your dick to harden and poke my ass just because I'm sleeping."

"What? No, shit. Sorry, it's just… you were moving around too much… it kept rubbing against you… I'm so sorry, sir."

Levi would have rolled his eyes if he wasn't already feeling the biting cold again. "Do you think that thing of yours can settle down soon?"

"Yes, please just give me a minute."

Levi waited, risking a glance down to check in between them, which wasn't really needed. Eren's dick was now pressing up against his thigh.

"Sir, sorry, but I don't think I'll be able to calm it down if you keep staring at me like that," Eren said, his voice small. There was an even darker dusting of red on his face now, reaching his neck and his ears.

Goddammit. "Eren, please don't tell me you're attracted to me and that you can't calm it down because of me."

Eren visibly gulped. "That seems to be the problem, sir."

"You have to be fucking with me," Levi deadpanned.

"That doesn't really help the situation, Captain."

Levi groaned. He was feeling the unpleasant coldness of the winter season on his back, and he wasn't pleased.

Goddamn Erwin and his stupid expedition and this sorry excuse of an inn.

He could ask Eren to leave and take care of it, but then he'd have to stay in the bed alone, without his human heater, and that wasn't something he wanted to risk.

"Fine," he finally said. He reached out a hand and, without warning, touched the bulge on Eren's pants.

"S-sir?!"

"Jesus, don't shout. If you haven't noticed yet, these walls are thinner than your underwear, and Hanji's just next door so if you don't want her barging in here while I take care of your pathetic erection then shut the fuck up for a minute."

Eren looked stunned, but Levi wasn't waiting for him to get over his shock. He palmed Eren through his pants, effectively eliciting a hiss from the brunet. Levi clicked his tongue, warning him.

"At least have the decency to finish quick, because it's fucking cold."

Eren nodded, eyes already turning hazy and half hooded. He inched forward, forehead touching Levi's and hands resting on Levi's hips. Although Levi appreciated the gesture, for the warmth, it felt oddly intimate to him.

Eren's breathing started to come out in heavy pants for air, hot and moist on Levi's face. He contemplated pulling out Eren's dick out of his pants, to get it over with sooner, but the mess that would follow stopped him.

"C-captain, I—," he was saying, but Levi cut him off.

"I'm helping you jack off, Jaeger. You can drop the formalities."

Shit, bad move. He just gave the brat a chance to call him— "Levi", a moan, "Harder. Please."

Well, fuck.

When Levi didn't answer, nor change the pressure on Eren's clothed member, green eyes looked at him. Eren stared at him and questioned him with those stupidly green big eyes (is everything about this kid big?) and then a curious look passed his face. Then he looked down between them.

"Levi, do you want help with that?"

Said man looked down, not really that surprised to see the growing strain in his pants. Also, was that amusement he heard in Eren's voice? "Fuck."

Eren reached out a hand and he barely stopped when Levi fixed him with a glare. "Just... returning the favor, sir."

His hand, although slightly hindered by the clothes, was hot on Levi, as was his length on Levi's palm. His movements were slightly clumsy, bent on trying to bring pleasure to his captain and Levi almost found it endearing.

"Get on top of me and move your hips," Levi ordered, his voice sounding low even to him. Thankfully, Eren complied without saying anything, hastily climbing on top of him and straddling him. Eren placed his crotch on Levi's and gave a tentative thrust.

"Like this, sir?" he asked while moving back and forth on Levi. His back arched, upper body moving away from the man below him.

"Shit, get down here and stay close to me."

Eren followed Levi's order, swooping down and fixing his face in the crevice between Levi's neck and shoulder. He placed a hesitant kiss on Levi's pulse point, the movements of his hips slowing.

"Don't bite or leave any marks on me, brat."

Eren nodded, picking up his hips and grounding down harder on Levi as he placed fluttering kisses all over the older man's neck. If Levi's was ticklish, he would be laughing. Eren moved upwards, his kisses now trailing along Levi's jaw, and then something wet touched his ear, licking him.

He didn't get the chance to complain about it being disgusting, because Eren pulled back and stared at Levi. Well, at his lips, particularly. He sighed, before gently threading his fingers through Eren's –surprisingly– soft locks, tugging him down as a sign that he was permitting it.

The kiss was almost funny, with Eren just pressing his lips down on Levi's, obviously unsure of what to do next. When he started to move his lips, the older man thought that maybe he really shouldn't indulge Eren's crush on him, because he was starting to think that the brat was, dare he say so, cute.

And the hot mouth on him was definitely using tongue to prod at him to open his lips.

Levi almost denied him, but he was thankful that he didn't because damn, did that hot tongue feel great.

Eren's kiss made an abrupt halt when Levi grabbed his ass, massaging the mounds in his hands and feeling the hot burn. He used his grip to guide Eren's hips into his, increasing the friction between them. Eren moaned into his mouth before pulling back and placing his lips on Levi's ear once again.

And then he bit Levi.

"Fuck— I told you not to bite," Levi growled at him. He felt the warm tongue lick the part where he was bitten, as if it was Eren's way of saying sorry.

"Just… too good…" he mewled, shameless. "I'm so close, Levi."

He seriously needed to stop saving Levi's name like that because it was starting to sound like a sinful word.

"Captain… can I…?" he asked, pulling back to look at Levi. Levi tried to ignore how the title sounded so wrong all of a sudden. Instead, as a response, he jerked his own hips forward, meeting Eren's hips.

Eren came, moaning into Levi's neck, and his slight spasms almost drove Levi to his own release. Before he could make a mess inside his pants, he pushed Eren off and pulled the cravat around his neck and got his dick out in record time, cumming inside the white cloth with a few pumps. He made a mental note to burn it.

After putting away the soiled cravat, he turned to Eren. They were both still breathing quite heavily, but there was a trace of a smile on Eren's lips as he stared at Levi.

Levi snorted. "Don't be too happy, kid. That's going to feel uncomfortable later."

"Shit."

Levi woke up with something hot and heavy weighing him down, only to open his eyes to Eren practically becoming one with him. Their legs were tangled together, and his arms were squeezed in between their chests, with Eren's wrapped around him like a vice. His head was tucked under Eren's chin, giving him access to the rich expanse of skin that was his neck and collar…

"What was that sound we heard from your room? It sounded like an animal got caught in a trap." Hanji, who was preparing her horse, asked Levi.

"Must have been a bug," he answered, moving to start on his own horse.

"A bug? A bug can make a sound like that?"

"A big ass bug."

Hanji stared at him for a while before finally dropping it. "Well, at least we're getting out of here. I almost froze my head off last night.

Levi hummed.

"That's odd… you're not complaining about it at all. And where's your cravat?"

"I have no idea what you're blabbering about," he answered, promptly turning away from the oddity that was supposed to be a human. He spotted Eren, who looked like he was having a slightly hard time walking and had a scarf around his neck which Levi didn't remember him having before, although the cold weather could be an excuse for that. The only reason Levi didn't start laughing was at the risk of Hanji piecing things together, which seemed like a very probable thing to happen, what with the way she was brooding on her own.

Hopefully, a whole week could pass before everyone finds out (and if he could hope, maybe never). Enough time for Levi to get Eren to warm him up again, maybe.
