Author's Notes: well, here goes. Another EreMika smut piece to feed your hunger. I tried a different approach in this story from my other smut piece, 'Yours Completely' with Eren being a real gentleman here instead of a real tease. I don't know which one you prefer? Haha. Credits to Anorable for the 3DMG Scars headcanon. As always, rate & reviews are appreciated. Enjoy!

P.S.: Edited slightly to change the wordings on 22/11.


This was all Armin's fault.

That was the only thing in Eren's mind as he walked inside the room he would be staying in for the night, and for the rest of the nights that they had to stay in this small house. Judging from how hard he moved them, it was as though his feet weighed one hundred ton each. His face burned as he recalled the scene from earlier this afternoon.

"You're going to share a room with Mikasa as long as we stay here," his blonde friend had said to him casually, to which he had replied rather outrageously, his loud voice giving him out way more than it's supposed to.

"WHAAT…?!" He stopped swiping the floor immediately and stared at Armin, his expression of complete shock. "What are you saying, I have to share with Mikasa? She can share with the girls, can't she?"

Armin dropped the potato he had been peeling and stared back at him, wearing the same startled expression. But where Eren's face had portrayed horror, his had been more of a subtle confusion. "There's not enough room. One of the girls has to share with the boys, and we figured it would be best to ask both of you. You have been living together since childhood anyway," he explained, eyebrows raised at his best friend's exaggerated reaction. "It should be no problem for you both, right?"

"It's…," Eren opened his mouth to protest, but closed it again promptly as he thought of an explanation behind his sudden agitation.

What could he say to Armin? That things weren't the same as when they're just children, and he used to slip in to her bed at night to comfort her when she had nightmares?

That he couldn't spend a night with Mikasa now because he, most likely, wouldn't be able to sleep, thinking of what to do and how to behave himself, so that he wouldn't cross that invisible line? The line that Mikasa herself had almost crossed, earlier when they were both on the brink of death? She had cried, grabbing her scarf, and thanked him for everything he had done for her.

And even in the midst of war, he couldn't help but feeling how pretty her tear-stricken face was. Her tears glistened slightly under the orange lights of afternoon sun, her pale cheeks blushed with a tint of rosy pink color as she held her scarf close to her face, her eyes lit up with a beautiful smile. Not once in the years that he had known her, had he ever seen her smile like that.

And it was because of him? Sometimes he still wondered what he had done to make Mikasa smile like that to him.

And honestly, in that moment, staring at her face as death was approaching them nearer and nearer, something just woke up inside of him. It was the same feeling he had felt the first time he had met her, the first time he had gotten her out of the kidnappers' dirty hands.

The feeling that he, somehow, had to stand up and protect this girl with his power. And so he got up and aimed his fist at the titan, triggering all the events that happened after. And they were able to come out alive, somehow.

But things weren't the same anymore, at least for him. And now Armin's telling him that he had to share a room with Mikasa, after all that happened? How the hell was he supposed to do that and not do something completely ridiculous to embarrass himself?

He couldn't say that to Armin. So instead of protesting he muttered, "Nevermind," and began swiping the floor again, much too restless to be considered calm, sending dusts flying everywhere. Armin watched his best friend silently, still questioning slightly but his sharp mind did not miss the point behind Eren's suddenly unusual behavior. Smiling, he decided to do a follow-up question to tease him a bit. "Do you want to share with me? But then Mikasa would have to share with the other boys," he said, deliberately not stating the solution of him sharing with Mikasa instead so Eren could stay with the boys. And to his amusement, Eren immediately cried out, "NO! I mean…," he tried to speak with a normal tone to hide his annoyance at the thought of Mikasa sharing a room with other boys, though his voice completely betrayed him, "No, I can stay with Mikasa, it's fine."

And here he was now, standing at the door of his and Mikasa's bedroom, feeling completely ridiculous. His eyes stared fixed at the small bed, much too small and cramped for the two of them to sleep in. He drew in a deep breath to calm his nerves.

Allright, I can do this, he told himself firmly as he finally stepped inside the room. If anything happens, I'll just sleep outside. Feeling a little bit relieved, he approached the bed where Mikasa had been sleeping in. She lay down underneath the blanket but her eyes were open, staring at him, questioning. "What took you so long?" she asked.

Calming myself down from the thought of spending the rest of the nights here with you, he answered inwardly, but of course he couldn't say that out loud. "Nothing important," he answered as he lifted the blanket and slipped in beside her. His skin accidentally came into contact with her warm, smooth skin under the blanket, and the effect was immediate. His heart to skipped a beat and his face grew hot, telling him that it had reddened uncontrollably. Fuck, he cursed desperately inside. This is bad. How the hell am I going to survive the night?

Suddenly he was over-conscious of them, spending the night side by side, skins brushing each other as they made every small move. Their bodies would be laying so close to each other. He would be able to feel her breaths, her heat next to him, her hair falling to her side, softly. He imagined his fingers playing, twirling with the soft black strands, letting them fall back softly as he stared into her dark eyes…

Stop. Just stop, he clenched his teeth and nearly punched himself out of frustration. All those dirty thoughts! It surprised him to know there was such a devil inside him. A devil whose biggest satisfaction would be to see him make a move toward Mikasa.

"Eren?" said Mikasa, aware of her adoptive brother's sudden restlessness. "Are you all right?" He heard her but he didn't answer. He was too distracted by the feeling of his blood rushing down, and to his horror he felt himself grew hard. By then he knew he wasn't going to stand this night, sleeping in the same bed as her. He wouldn't be able to, without unleashing the beast inside him and ravish her outright.

"I think I'm going to sleep outside after all," he said, getting himself out of the bed almost immediately, his eyes purposedly looking everywhere but at her. He couldn't do this. There was no way he would spend the night with her. He leapt to get out of the bedroom, but was surprised to feel the grip of her hand in his the next second, preventing him to advance further, forcefully making him turn.

"What's wrong?" she asked, concerned. "You're acting weird."

He pulled out everything at once and blurted out the first excuse that came to his mind. "It's… it's hot in this room. I need some air."

"It's almost winter, you'll freeze sleeping outside without a blanket." And he fell silent, realizing that she was right. Her gaze pierced him as she eyed him with increasing scrutiny.

"What's wrong?" she asked again, and he was forced to be honest this time.

"I couldn't… I can't.. sleep in the same room with you," he muttered. Her grip on his hand grew tighter. "Why not? We used to do this when we were kids," another question followed, her voice as stoic as ever. And it frustrated himself completely that he nearly shouted when he answered.

"Because it's not the SAME anymore!" he finally stared at her straight. Did she really not think about anything, being alone in the room with him, until morning? Was it just him after all, having all these thoughts for her? This was Mikasa, she was his sister. He's not supposed to have these feelings for her. He's not supposed to. But it's getting harder to control this devil inside himself and honestly, if she drew even an inch nearer to him he wouldn't be able to hold back anymore.

He watched as her eyes widened with surprise to his answer. "It's… not the same as when we were kids! How am I going to be able to spend the night with you, when all I could think of now is….," he stopped himself before he could say nasty things about you. "Eren…," she muttered, sounding astonished, but fell silent soon after that. It was not the first time for her seeing him explode with outrage. Eren was always like that, after all. Impulsive, hot-headed, always bursting out his feelings immediately but calmed again soon after. She was used to it. Her face remained impassive but she still held his hand tightly. Realizing that she really wouldn't let him go, he sighed exasperatedly.

"Nevermind, you go sleep. I'll stay here," he said finally, sitting himself down on the floor beside the bed. He was determined not to go back to the bed and embarrass himself even further, when suddenly he felt her arms, smoothly gliding around him, caging him in.

And before he realized, she had pulled himself closer, her voice soft in his ear, her breath tickled his neck as she whispered, barely audible but at that time it was louder than a shout to him.

"You said we'll always be together." His heart seemed to stop and his blood began to rush rapidly as a response. Her voice, her arms… She was too close. Way too close. He had to let go of her hands, or else… he gulped.

"What of it?" he said in a voice he almost couldn't recognize as his own. Her sudden action took him aback, but in the same time he was surprised to find that he enjoyed it. The secure, warm feeling of her hands around him for once, and though he knew he should, he couldn't bring himself to shake them off.

"You can't do that if something as small as this bothers you," she continued. Her fingers softly tilted his head back and before he knew it her lips had found his. He held his breath. Desperately he tried to reason, to resist her, to put up his wall of defense and not go further. But by then he knew it was futile to deny. He was lost completely in her kiss, unwillingly submitting to her. And when she let him go, he had only wanted her more.

He stared at her face, slightly panting. She looked calm and composed as ever. But slightly, just slightly, he could see her pale skin blushing.

And by then he knew he wouldn't waste this chance.

He climbed the bed, moving faster than what he ever imagined he could. His hands found her wrists and grasped them tight. His thighs quickly moved to grip either side of her waist, as he brought himself on top of her, firmly locking her in place beneath him.

"Er…," she gave out a cry of surprise but he shushed her into silence. "Don't expect me to hold back after that," he said, his breaths quick and shallow. His voice deep, full of desire.

"I don't," she answered, much to his surprise. He eyed her, trying to find traces that she's lying, but her face was filled with nothing but uncanny sincerity.

"You sure… you won't regret this?" he asked carefully. She returned his gaze and slowly, slowly her lips parted and he heard her speak.

"No. I want you."

Her words nearly sent him over the edge. He wanted her. He desperately wanted to touch her, feel her, to explore every inches of her until there was nothing left unexplored, and even by then he knew he still wouldn't be satisfied.

And to know that she wanted him back was all he ever needed to release himself. She had said the wrong thing to the wrong man tonight. She had unleashed a beast from its cage and it was too late now to turn back.

"Don't say I didn't warn you," he said, before he fiercely attacked her lips with his. He released his hands from her wrists to slide in under her night shirt, caressing the smoothness beneath. Mikasa's body shifted slowly beneath him, shuddering at his touch. A quiet sigh escaped her lips, quickly muffled by his kiss. He let go of her lips and pressed a string of kisses down her neck, nuzzling it slightly and smiled as he felt her goosebumps rising. His hands worked swiftly to unbutton her shirt, it didn't take long before he took it off, and her top was bared in front of him. He could see faint marks of 3DMG belts etched on her chest, just above her breasts, dark against her pale milky skin. He moved his hand to unclasp her bra but she suddenly shied away from his touch.

"Don't," she said, but he grabbed her fast, unwilling to let her get off so easily. "What are you saying?" he said, smirking mischievously. "I'm not letting you turn me on and then go. It's not fair, Mikasa." And to his amusement she blushed.

"I said it, didn't I?" he playfully moved his hands down her side, watching as she went limp with desire, her iron-clad self-control withered completely. It was amusing to realize what his touch could bring to her. He should have done this sooner, whenever she tried to shove him up her shoulder. "Don't say I didn't warn you. You brought this up, so now bear the consequences."

And she was silent, though her face was scarlet as he took off her bra, playing with the softness of her breasts. His hands squeezed as he licked them teasingly, bringing them into his mouth and smirking as he felt her breath starting to quicken, her body unwillingly arching upward at the pleasure, yielding at his touch, asking for more. Softly his tongue traced its way through her abs, exploring inches by delicious inches downward, where he planted a soft kiss on the place right above her womanhood. Without speaking, he unbuttoned her pants, quickly sliding them off with her help, tossing them aside. And she was completely naked beneath him now. She was flawless – beautiful. A complete, wonderful beauty wrapped in flesh and bones, and he couldn't help but to admire her.

He laid his head quietly on her stomach before proceeding downward to the warmth between her legs. And by then he heard her gasp, instinctively closing her thighs, but he shifted his knee to hold them apart. He touched her inner thighs lightly, his gaze was soft and knowing as he smiled at her. It's almost funny how Mikasa was very insecure about her looks and everything about her body, while for him she had never been any less than perfect. "Relax," he said, and almost immediately he felt her eased beneath him. He was surprised at how good he was handling his first time. To be honest he had no idea how to do this, he never had any experience. But somehow, just somehow, he only wanted to guide her slowly through her pleasure, and he knew how to do it.

He parted her thighs with his hands and brought his mouth to the unyielding softness between. His eyes were closed as he flicked his tongue out lightly, playfully, teasing her clit and exploring the part of her body yet known to him, wanting nothing but to give her pleasure as much as possible. And soon he felt her began to grow wet. Her breaths were choppy and heavy, moans after moans escaping her lips. Her hand grasped his hair tightly and her hips jerked upward, closer to his mouth as she pushed the back of his head, silently asking him to go faster, deeper, to the tiny little spot where she was yearning to be touched, and he obeyed. He fastened his pace, reaching deeper, until all she could feel was the powerful sensation of his tongue on her most intimate part and she broke. Before she realized she had screamed his name out loud, unaware of everything else, shuddering uncontrollably at the pleasure he had brought her and wanting nothing more but for him to enter her.

He released her, panting slightly but amused at how much he could please her. Quickly he tossed off his clothes, baring himself as completely as she was and positioned himself, ready to enter her. Hesitating slightly, he caressed her face before saying, "Tell me if I'm hurting you, OK?"

Mikasa nodded, and she closed her eyes as he began sliding himself in her. She had heard that it's supposed to hurt the first time, but it was going to feel really good soon after that. He entered her quickly, allowing her a moment to adjust before he began moving in a slow, easy rhythm. She let out quiet sounds of pleasure which soon turned louder as he went faster. Their bodies moved in harmony, filling each other in until they were lost completely within their own world, neglecting everything else around them. He wanted her and she wanted him, and all they needed in that moment was each other. The pleasure built inside her gradually and she thrust her hips up, letting him reach deeper to her core. She allowed him to guide her, pulling her closer and closer to where she wanted to be, until suddenly she reached it and everything seemed to explode in a brilliant white light. A tremendous amount of pleasure washed over her, and she cried his name out, screaming until her lungs were completely out of air. Never in his life had Eren ever heard Mikasa calling out his name like that, and it drove him to go even faster, thrusting into her until he finally climaxed inside her warmth. He allowed himself a moment before he collapsed onto her, their bodies were slick with sweat. Her hand immediately tangled his soft brown locks, and he pressed his ear to her chest to hear her heart beating rapidly. Nobody spoke for a moment as they tried to regain their breaths.

"Did it hurt...?" he finally asked.

"A little," she answered quietly.

"Did you…like it…?" but of course he didn't need to ask that. Her reaction had said it all.


Everyone was behaving weird the next morning.

Mikasa found it strange as they quickly answered her 'good morning' with a rather awkward greeting, their eyes deliberately not meeting hers. As she sat herself quietly beside Eren on the breakfast table, wondering what was happening, suddenly a loud, crass voice of Corporal Levi prompted her from behind.

"So, Ackerman. From your reaction last night it seemed like Jaeger is really good in bed," the sarcasm in his voice couldn't have been clearer. Mikasa felt her heart stop while beside her, Eren suddenly choked on his tea, coughing uncontrollably. She had forgotten everything last night, losing herself to Eren's play, not realizing that she had probably been so loud. Last night had been so quiet, and judging from how small this house was, they could all probably hear the noise that she, or rather they, had made. Her body went cold at the thought. She sucked in her breath and stared immediately at Eren, his looks mirroring the same horror on her face.

The silence that followed in the room after was louder than any words as Eren and Mikasa stared down at their laps, their faces boiling scarlet.
