ErenXArmin. Not too explicit. I give it a 3 on the sexy meter.

"What do you think sand feels like?"

Armin's eyebrows shot up momentarily at the question, pausing his scan of the map to think about it. He remembered how Eren—before entering the training corps—would always ask these types of questions as if Armin had the answers for all of them, that childish grin and expecting smile spurring him on.

Armin tried not to let the intensity of Eren's teal-like stare get to him as he slowly answered, "Kind of like dirt, I think…I remember reading that it was made up of finely divided rock particles. So, maybe even that spice that Krista uses when she makes her stew. You know, the one that you and Jean tipped over and made a mess of when we were setting up camp?"

Eren puffed out a sigh as his head rested on the tabletop. "It's not my fault that horse-face can't keep his mouth shut."

"What were you arguing about anyway?" Armin asked detachedly, measuring the distance from two points on the map he was studying. He heard Eren shuffle around and could see his arms fidget from his peripheral vision.

"…nothing."

Now Armin looked up. Eren rested his chin on his arm, eyes trained on the wall and lips set in a stubborn pout. The blonde cocked his head to the side and nudged his friend's foot with his own boot.

"Look, I know you and Jean butt heads, but at least try to get along with him? He has his heart in the right place, you know—"

"Yeah, it's up his ass, along with his head."

Armin gave him an unimpressed look and sighed, returning to the map the corporal had asked him to look over in order to organize their next scouting mission. "Well, even if I don't agree with him 100 percent of the time, I still trust him. Even if he did call me gross."

Suddenly Eren's head shot up. "Gross? He called you gross? When?"

Armin blinked. "Calm down, I'm over it already. He just—"

"Why did he call you gross?"

"It doesn't matter, Eren."

"Yes it does."

"No, it doesn't. I told you—"

Eren stood up with a strange look in his eyes that Armin had never seen before. "That asshole horse-faced dick can't keep calling us gross, damnit! I'm gonna find him right now—"

"Us?"

Eren stopped ranting.

"What do you mean 'us'? So Jean called you gross too?" Armin rolled his eyes. "Must be a favorite word of his, I guess. Why would he call you gross?"

Armin watched as Eren's face acquired a pink tint. "He—I don't know! How the hell am I supposed to know how that moron thinks? Why would anyone consider the two of us gross together? It's so stupid! I mean just because—"

Eren's eye met with Armin's as the shorter of the two stood up and leaned forward. "Eren, you're not making any sense. And you're getting way too worked up over Jean's petty insult. What's really going on here?"

Armin watched Eren carefully, noting his blush turn deeper, hands ball into fists and lips pressed in a straight line; all things he remembered from his childhood days but somehow seemed so much more…more what? Not cute. Not endearing. Armin would never think of his best friend, Mikasa's love interest, as attractive, no not by any standards—

—even if Armin suddenly felt a pair of rough, hot lips pressed against his own, curious yet shy, wanting but holding back at the same time, shifting ever so slightly as Eren breathed through his nose. And there's no way Armin would press back after a few seconds, a small sound escaping him as the table's side pressed into his abdomen and as Eren's fingers moved on him, running through his hair and leaving shivering touches on his neck and shoulders.

The map crinkled under the pressure from Eren's hand as the brunette leaned forward and deepened the kiss, angling his head and opening his mouth just slightly, running an inexperienced tongue over Armin's lips and giving his silky hair a slight tug. Armin flinched and pressed against Eren harder. Eren nipped at his bottom lip as he gave his hair another tug, this time a bit more rough.

Armin moaned.

The sound stopped Eren in his tracks and he watched as Armin's horrified face turned red, those brilliant blues lowering to the floor and hands coming up to cover his face.

"I—I, um, should go see the corporal about this…uh…"

Eren felt the heat pooling in his stomach and knew that Armin had to feel the same. He clumsily leapt over the table and put both his hands on Armin's shoulders, forcing the blonde to meet his eyes.

"Armin, I—"

They both jolted as the doors swung open and in strolled Jean and Reiner in mid conversation.

The two arrivals looked at the scene of Eren and Armin sporting red faces and disheveled hair blankly, setting down the sacks of grain they had been carrying and walking out just as casually, closing the doors behind them. Before Eren and Armin could do anything, they heard Jean from the other side of the doors.

"I told you they were gross."
