The kiss started slow and sweet before they released and looked into each others eyes.

At the initial contact of their lips, Eren thought it was extremely unfair to himself to give into this moment considering how much he was holding himself back, but Mikasa was being extremely assertive in ambushing him in his bedroom.

Suddenly, Mikasa pounced on him. She started kissing him again, setting a fast pace, leaving Eren struggling to catch up. She ran her fingers through his hair and stuck her tongue in his mouth.

He kept trying to remind himself that he was supposed to be holding back until Mikasa made it clear she was comfortable.

And then it hit him.

Was this not her expressing she wanted more? Wasn't this the exact moment he had been waiting for? Once the reality of the situation sank in, he kissed her back full throttle and decided to take over.

He grabbed her and pushed her against the wall, leaning over her, resting his hands above her head.

Mikasa grabbed behind his back and pulled him closer while biting hard on his lower lip. She slid her teeth across the entirely of it slowly, until their mouths released.

"Damn." Eren breathed before grabbing her face with one hand and pushing it up to the ceiling, giving himself access to her neck. She moaned at the action and began running her fingers through his hair as he attacked her neck with bites and kisses. Stopping to suck on her pulse which was racing.

A desire for him to know what this felt like came over and she pushed him off of her and onto the bed. She crawled on top of him, straddling him and began kissing his neck and nibbling his ears.

Mikasa ran her hands down the front of his body, stopping at the top of his pants, causing him to twitch and shudder under her touch. She tugged at the base of his shirt indicating she wanted it off. Eren lifted his upper body enough for Mikasa to slip it off over his head.

Now that Eren was bare from the waist up, Mikasa admired the view. She decided the best way to fully appreciate just how defined his muscles were, was with her mouth. Starting at the base of his neck, she started to kiss slowly down his body.

"Woah Mikasa…" Eren breathed, arching is neck back.

She was like a starving animal. Without meaning to, Eren had pushed her to her breaking point, and in this moment he was thankful he did. Because the way Mikasa was acting, the things she was doing to him, was truly the stuff of his dreams.

She licked at his abs and looked up at him. He grabbed a fistful of her hair and stared at her with lidded eyes, breathing heavy.

She continued down past his belly button before she stopped. She could feel his erection growing underneath her chest.

It fired her up more.

She quickly kissed back up his body, onto his neck, and over his jawline until their lips met again.

Eren grabbed at the back of Mikasa's knees and pulled her up so that she was straddling him again and she was sitting directly on his growing length.

He lifted his hands until they were on Mikasa's back and slowly rotated them so that they were on her stomach again. Gently, he let his fingers graze her under boob through her shirt. She breathed heavily into his mouth and got more passionate with her tongue, clearly begging him to continue.

Feeling her actions had more than proved she was okay with pushing it tonight, Eren slipped his hands up onto her boobs. He couldn't believe how amazing they felt in his hands. When Mikasa didn't protest his actions, he began to squeeze and fondle them. Mikasa broke her lips free from his to throw her head back and moan.

Her reaction sent Eren into a frenzy. He suddenly became aware of the cloth in between his hands and Mikasa's bare tit and was furious. He reached down to the base of her shirt and ripped it off over her head without thinking.

Realizing he had done so without making sure it was okay first, he grabbed both sides of her face and pulled her down, kissing her again. He didn't want to look in case she wasn't comfortable with this yet. As they kissed, he could feel her hard nipples brushing against his chest.

Once again, instinct took over and he pulled her down hard onto his body, desiring to feel more of her breasts. The feeling of stomach to stomach contact was incredible too. He grazed all along her bare back and squeezed her tightly feeling her breasts squish against his pecks.

When he once again began rotating his hands to her stomach, she lifted her body off of his to show she wanted his hands on her.

He broke free from her lips and looked into her eyes.

"I want to see them." He said breathlessly. "I need to… can I look?"

She nodded giving Eren permission. He lowered his gaze, heart pounding, to see her large, perfect, circular breasts sitting just inches from his face.

"Wow…" He said eyes and pupils widening. He couldn't wait any longer, so he slipped his hands from her stomach up to her bare chest. Mikasa's breath hitched at the action. Eren felt the hardness of her nipple in his palms and adjusted his grip so that he could pinch the firm bulbs between his fingers. She panted at his boldness, clearly enjoying his display of dominance.

Quickly, just touching them wasn't enough. He needed to taste them. He grabbed one of her tits hard and forced it up to his mouth. Mikasa gasped but realizing what he was doing, she melted into his touch.

He sucked on them like he was a dying man and this was his only chance at living. Still breathing heavy, Mikasa ran her right hand through his hair and pulled at the now short strands.

She squealed at the sensation that shot through her body when he gently bit down on her nipple.

He decided he had to make sure the other one didn't taste any different, so he released his mouth from the left one, grabbing it with his hand instead, and immediately captured the right in his mouth.

He released his right hand from her left tit and sent both of his hands down to her ass.

He grabbed as hard as he could at her ass cheeks, keeping her right breast in his mouth. Mikasa was equally as thrilled with the events that were transpiring, and she couldn't have kept in all of the noises she was making even if she wanted to.

He grabbed her butt firmly and began grinding her center down against his erection, moaning loudly at the contact.

Mikasa felt a shock of pleasure shoot through her body that she had never experienced.

"Eren…." She whimpered.

At the sound of her calling his name like this, Eren released her ass and grabbed at the top of her pants and began trying to pull them off. He tore his mouth from her breast and brought his lips back up to her face meeting her lips once again.

Mikasa was happy she was so turned on, or else this action would have sent her into a panic. But instead she lifted her hips and assisted him as he pulled off her pants. Now she had nothing on other than her panties.

In one swift motion, Eren flipped them around and braced himself on top of her. He stared down at her for just a moment, taking in the sight of her messy hair and swollen lips, before beginning to do to her what she had done to him.

He began his decent of kisses down her naked body. She breathed heavily as his face passed between her boobs and her stomach rolled at the contact of his soft lips as he made his way down to her belly button.

When he got to the base of her stomach, he began reaching his hand down in between her legs.

She squirmed a little, realizing what he was doing.

"Wait." She said.

Eren immediately paused and looked up at her.

"You want me to stop?"

"Well… no.." She admitted. "I'm just a little nervous."

"Then trust me." He said back. "And if at any point you're uncomfortable, you let me know and I'll stop."

"Okay."

Eren continued his pursuit and began rubbing at Mikasa's center.

Instinctively, Mikasa's back arched at the pleasure.

Eren noticed she was very wet. Rather than being intimidated by this, it added fuel to his fire.

He touched around the area through the cloth, seeing where her reactions where the most dramatic, before honing in on where he assumed her clit was. He began rubbing the area in slow, deep circles.

Once again, the sounds Mikasa emitted were like a drug to him and he desired more than anything to keep them coming.

He grabbed at the top of her panties, and began pulling them down. To his surprise, Mikasa didn't stop him. When he finally pulled them free of her ankles, he looked at her most private area and smirked.

"Well she's pretty." He said in a sultry voice, gaze not wavering as his pupils dilated even more.

His words and tone made her stomach do a cartwheel and she knew she would let him do whatever he wanted to her.

Before she could say anything back, he was on the move. She watched in what felt like slow motion as his face dropped in between her legs.

He began sucking, licking, and biting at the place he remembered her reacting the most to. At the same moment, he plunged a finger into her opening and slowly caressed her insides.

Mikasa found herself wondering how he was so good at this and seemed to know exactly what he was doing, but figured it was because he was naturally good at most things he set his mind to. All the same, she did make a small mental note to ask him about it later.

Eren didn't allow her mind to wander for long. He was sending ripples of pleasure through her body with his tongue and finger.

If Mikasa thought she was being loud before, it didn't hold a candle to how loud she was being now. She moaned carelessly as each wave hit her.

Eren inserted another finger and continued his rhythm. Mikasa enjoyed the added fullness and felt her pleasure tipping over the edge of something… and that something was big and about to happen.

"Eren!" She whimpered. "I'm gonna-" but she was cut off by her orgasm. She had never experienced one before, and this one was especially powerful.

For half a second, she genuinely wondered if she was okay as this was a completely new sensation. She felt like her soul had left her body, leaving her unsure of which way was up and which was down. She allowed herself to give into the feeling of euphoria and gave her loudest moan yet, it came out at almost a scream. From what felt like far away, she could hear Eren saying,

"Yes Mikasa…. Good girl."

This only made her come harder.

When she was finally finished, and her senses returned to her, she looked down at Eren still in between her legs.

"Holy shit Eren..." She said breathlessly. "How the hell did you know what to do?"

Eren chuckled and got to his feet, clearly extremely pleased with himself.

"Well most of that was what I naturally felt I wanted to do. Your reaction was just the cherry on top. Plus guys talk, and I always paid attention just in case I ever got you alone." He smirked, sliding his pants off.

Now he was in nothing but his underwear, his length clearly visible through the thin clothing.

Mikasa couldn't believe the size of it and wondered how this was even going to work. She quickly reminded herself of what Eren had just done for her and she became determined to at least try.

Eren crawled back on top of her and whispered in her ear. "Ya know what else I remember learning?"

"Hmm?" Mikasa hummed back.

"Women can have more than one orgasm in a row…. Wanna try for another?" He asked in a seductive whisper.

"Yes… but first," Mikasa said back, reaching down and brushing his huge length with her finger tips, causing Eren to inhale sharply. "Let's make sure you're taken care of."

She met his lips again and grabbed at the top of his boxers, pulling them down allowing Eren's erection to spring free. In an instant, she was grabbing it around the base, Eren moaning into her mouth as she went. He was pretty convinced he would never be satisfied with his own touch again after feeling her hands on him like this.

Mikasa had no idea what she was doing, but it felt right to start pumping it so that's what she did. Before long, small white fluid seeped out of his tip. This, along with the fact that Eren seemed to be dying above her, she was pretty sure it felt good.

A bold desire came over her and before she could question if it was weird or not, she gave into the heat of the moment and went with it.

Using her thumb, she started playing with his tip getting his pre cum all over her fingers. After a few moments of this, releasing Eren's mouth and opening her eyes, she brought her fingers up to her mouth and licked off the fluid not breaking eye contact while she did so.

"Holy hell…" Eren breathed, clearly enjoying it.

Was this really his sweet, shy, submissive Mikasa? This was even more than his fantasies could even have predicted. And this was only their first time? He got goosebumps imagining their future.

Mikasa was thinking along the same lines. He had always been so sweet and loving to her, but this? This was a whole new side of him she didn't even know existed.

"Who are you right now?" Eren found himself asking. "You're so sexy it's unreal." He whispered, bending down to place soft kisses along her neck.

"Same could be said for you." Mikasa said through moans. "I had no idea you had this in you."

Eren pushed himself back above her and gave her a smirk, looking at her with those animated, determined eyes she knew so well.

"I thought we established this already." He said barely above a whisper, lowering his lips to her ear. "I have a dark side remember?"

They started making out passionately again. He reached down in between her legs and stuck his ring and middle finger inside of her, causing her to gasp. Using his palm, he rubbed at her clit. Because she had already had a mind blowing orgasm, he had to push even harder to hear noises of pleasure coming from her, but this was no problem for someone as strong as he was.

Once she was plenty wet again, Eren released his fingers from inside her and grabbed his length, teasing her entrance with the head of his dick.

He did this for a while, occasionally catching her entrance, making Mikasa think he was going to push in deeper, before he pulled away again. He was clearly trying to drive Mikasa crazy.

If Eren thought he had been holding himself back these past months, it had nothing on this moment. It took the most intense will power he had ever displayed in his life to hold off shoving his entire dick into her as fast as he could.

The main reason he was holding back was that he had heard the first time having sex hurts for women, and that getting them extremely warmed up was important. So he was going to keep doing this until she was literally begging him to enter her.

And it didn't take long. Mikasa was past her breaking point. She tore her lips from his mouth and practically yelled,

"Ahhh Eren… please!"

"Okay." He said as she looked up into his eyes again. "But Mikasa, this is probably going to hurt, and as bad as I want to be selfish, if it's too much, you tell me immediately." He said very seriously.

"Okay." She responded so that it was perfectly clear to him that she understood.

Slowly, Eren pushed his length into her, inch by inch. A sharp pain shot through her at the stretch and she squeezed tightly around his neck.

"You okay?" He asked, barely able to speak. Feeling her warm walls enveloping his dick made it so hard to remember that she was in pain, but he was determined to stay focused.

"I'm fine." Mikasa winced. "We have to get past this phase and then it will feel good right? Keep going."

"Are you sure?"

"Yes Eren. I love you so much."

At her words, he pushed further until at last, he bottomed out with a moan. He stayed as still as he could inside of her despite every cell in his body telling him to start thrusting.

After a few moments, Mikasa's face softened and she stopped looking like she was in pain. All of the warm up Eren had given her really did go a long way.

"Okay. You can start moving." She told him.

Eren had been practically holding his breath. But as he started pulling out a few inches, before plunging back in, he felt himself relax and surges of pleasure began taking over.

Eren truly believed he had died and gone to heaven. Though he knew, it was much more likely he was going to hell. If this was what hell was, and this could be what his afterlife consisted of, he would die willingly.

"Ahhhh…." He sighed as he began picking up the pace. Mikasa even seemed to start enjoying it as she was arching her back and throwing her head and arms back, mouth wide open.

"I love you too." Eren said through harsh thrusts. "So, so much."

Too soon, he started to feel like he was going to come. He was way too turned on and had to force himself to think of something, anything else. But even with that, he wasn't sure how long he'd last. So he reached down and started rubbing Mikasa's clit again, hard.

She moaned lightly underneath him, the sound made it even harder to hold on. He rubbed as hard as he could and bent down to bite on her nipple. Adding the nipple play made it enough, and Mikasa broke into her second orgasm.

Eren could feel her come releasing onto his dick and it sent him over the edge despite his efforts to hold out.

As fast as he could, he pulled out of her and she gasped and the sudden emptiness. He moaned loudly and unapologetically into the room as he released his come onto her stomach. Mid orgasm, he bent down and kissed her softly, milking the euphoria for as long as he could.

Once he was finished he tore his lips away and felt around for his shirt on the bed. He grabbed it and cleaned Mikasa off with it before throwing it on the ground and collapsing next to her on the bed placing his hands behind his head looking at the ceiling trying to catch his breath.

"Wow…" He said through his panting. "That was-"

"Incredible." Mikasa cut in.

Finding he could breathe again, Eren grabbed Mikasa and pulled her into him, holding her tightly.

"It really was wasn't it? Thank you Mikasa. I really don't deserve you." He said looking down at her. It seemed he had gone back to being sweet Eren.

"No thank you!" She responded. "I had no idea what I was doing but because you took the lead, it was so much fun." She paused for a moment before she remembered she wanted to ask him about that.

"Speaking of… you were actually a little too good at some things. Are you sure you've never done this before? Or maybe looked ahead in your memories to get extra good at all this?" She waved her finger in a circle above them indicating what she meant.

Eren chuckled and she could see just how much she was boosting his ego.

"No I swear I'm completely inexperienced. You're my first and only lover. But… I did find some adult books in the library when we first joined the survey corps and stole them. They were mostly educational, explaining anatomy and do's and don'ts about sex but as you know, I'm extremely obsessive. So I studied them pretty thoroughly. That and guys talk and I picked up on a few things here and there."

Mikasa smiled at him saying she was his only love. Feeling satisfied with his answer, she nuzzled back into his neck.

"Good. You had me worried for a second there."

"Worried isn't how I would describe how you were acting…" Eren teased grabbing at her bare butt.

"Hey!" She lightly smacked at his chest. "Don't go making fun of me now."

"Oh I wouldn't dream of it!" Eren mocked. They chuckled together before resuming their cuddle.

"There's one more thing we need to talk about." Eren said in a serious tone causing Mikasa to worry. "Where on earth did YOU learn everything you were doing?"

"I genuinely have no idea!" She replied. "Apparently, unlike you, I was completely focused on our missions during our military years. I have absolutely zero experience or idea what I'm doing. I just kinda did what felt right in the moment I guess…"

"Mmm" Eren hummed. "Well if that's you inexperienced, then I'm extremely excited." He whispered in her ear. "Once we get some more practice, who knows what's in store for us."

Mikasa's stomach did a flip at his seductive tone. Was she really still horny? Trying to match his energy despite her more shy nature, she responded.

"I guess you're right. Practice does make perfect." They were nose to nose now, looking into each other's eyes.

Eren didn't want to underestimated Mikasa's sex drive as she had already surprised the hell out of him tonight, and he was feeling nervous about the fact that he didn't know if he could perform again if they got back into it. But he was positive after some rest, he would be more than ready to go at it once more. So he broke his face away but continued holding her naked body close.

"Speaking of my research, it said you need to go pee as soon as you can or you could get an infection."

"Why just me?" Mikasa wondered feeling annoyed.

"I genuinely have no idea." He responded so innocently, it made Mikasa giggle.

"Fine. I'll be right back."

Eren watched as her naked body got off the bed.

"Damn you're hot!" He called to her as she got to the door.

Suddenly feeling shy and exposed, Mikasa made a worried noise and rushed out the door. She could hear Eren laughing as she ran to the bathroom. She smiled despite herself at his compliment.

When she got back to his bed, she crawled on top of him and plopped down comfortably under the blankets. Eren was still not used to having a naked woman on top of him, much less Mikasa, so he was less relaxed at her actions. He began tickling up and down her back, enjoying the full body contact.

Eventually, Mikasa started breathing heavily, and Eren realized she had fallen asleep. He smiled when he realized and wrapped his arms around her and gave her a gentle squeeze.

"Goodnight Mikasa." He whispered. "You really are the best thing that's ever happened to me."
