Living in an isolated cabin meant that they had a lot of leisure time and in recent weeks, the couple had decided one of their favorite things to do was to read books.

Mikasa gravitated towards books about wars and history, while Eren found himself wanting to read books about science. He loved learning all about the Earth and all the different things that covered it. He loved volcanoes, the different types of rocks, plants, mountains, erosion, the ocean and all of its complexities and more. He would tear through book after book, flying through them even though they were filled with terminology he didn't yet understand.

The outside world was still so fascinating to him as none of this information was available to him within the walls. Mikasa would make fun of him for his new obsession and called him "Hange," a fair number of times.

But Eren didn't care. He really would have liked to have been a scientist in another life. After all, his dad was a doctor, the bug for learning was literally in his DNA. He reported all of his new discoveries to Mikasa and though she teased him, she genuinely found it fascinating as well. But more than that, she felt her insides melt anytime he perked up in preparation to tell her every detail of the things he was reading. It reminded her so much of young Eren and she could listen to him talk like this for hours.

After a week of reading every book imaginable, they made their way to the library to find more. That's where he stumbled upon a book about human anatomy.

One specific book was about women's anatomy and since the only thing he felt more passionate about than the outside world was Mikasa's body, he rented it at once eager to learn more.

Summer was coming to an end and especially in their cabin up in the mountains, the nights and early mornings began to have a bite of cold to them. So when they got home, Eren cut up some wood to burn and put it in their fire place so that they could cozy up next to the fireplace and read their books.

"Women are so complex compared to men! Did you know?" He asked Mikasa one night.

"Well yeah… of course I'm aware to some extent. But tell me what you're reading specifically."

"Apparently there are only six days in a whole month that a woman can get pregnant, and ironically enough that week is also when their hormones make them want to have sex the most. How cruel is that?!"

"The more you learn, the more you'll see most of female anatomy is cruel Eren. I'm not shocked by that at all." She replied, not caring to look up from her book.

"That may be true, but I still want to know everything there is to know about it."

Mikasa started her first period since being sexually active the day they were meant to head into town and do a restock of their things. When she had first told Eren that she was bleeding, he panicked and ran to her trying to find the injury. When reality sunk in, he jumped on the opportunity to show off his new knowledge so he insisted she stayed home and took care of herself.

At first Mikasa was irritated with him. She had been having periods for years now and she never let it hold her back. If she could literally fight for her life as a woman, she could easily go into town. But she sensed that Eren really wanted to be a gentleman so she allowed him this victory and stayed home.

Eren went into town alone and did all of the shopping by himself. When he was finished, he went to the candy store. Inside was the blonde girl who was Blake's daughter Daisy. Knowing that Mikasa would be unhappy if he talked to her, he did everything he could to avoid her. It was to no avail. The second she saw him she walked right over to him.

"Hey! I've been hoping I would run into you again." She said enthusiastically. "I wanted to tell you how sorry I am about my dads behavior. He really can be such a jerk. I'm Daisy by the way! What's your name?"

"Thank you for apologizing for your dad, but it really is fine. I'm the one who should be sorry since I threw the punch." Eren replied not looking at her as he continued his shopping, ignoring her request to know his name.

"Oh you're okay! If anything hopefully it knocked whatever is loose in his brain back into place!" She laughed at her own joke. But Eren didn't give her an inch and kept his face neutral.

Feeling a little embarrassed but also determined to get some answers out of him since Mikasa wasn't with him, Daisy pushed on.

"Well I don't mean to pry but where did you guys come from? I feel like one day you guys just showed up and now you're the talk of the town!"

Now she had caught his interest because he didn't care to be rude to her, but if what she said was true then they could be found out. He whipped around.

"What do you mean we are 'the talk of the town'? Who talks about us and why? What specifically do they say?"

Daisy lost her breath for a moment at his green eyes but when her brain caught up to her body, she responded.

"Oh yeah! This is a small town ya know? And we get very few outsiders so when two young people showed up out of nowhere of course people started talking."

"What specifically do they talk about Daisy?" Eren repeated with a hint of annoyance.

"Mostly the nature of you and that Hizuru woman relationship. Everyone is curious if you guys are married or grew up together or something else? We also wonder where you came from and if you plan on staying?"

Feeling relieved that it mostly sounded like stupid gossip, Eren took a breath. But all the same, he felt it was important to try and squash rumors about them in case they escalated.

"Well first of all, the 'Hizuru woman's' name is Rebecca and she is my wife. We got married young and decided we wanted to just try living completely on our own. We both grew up in the same town in Marley." He said turning away from her. "Feel free to tell anyone that's being nosey." He said as he walked away.

Daisy felt disappointed at the news of him being married, but still called after him.

"Okay… It was nice talking to you!"

Eren simply raised his hand up as he walked away and continued to the register to buy the items he had collected during the conversation.

By the time he was done paying, Daisy had left the store and he was thankful she had. He hoped he had finally squashed these rumors, and praying no more came about to draw unwanted attention to them.

Feeling content with the surprise gifts he had gotten for Mikasa, he headed back up the mountain.

By the time he got home it was nearly dark out. He walked into Mikasa's room and found she was asleep. Smiling to himself, he decided he would have dinner ready for her when she woke up.

"What smells so good?" Mikasa asked wiping her eyes.

"Awe hey!" Eren said, dropping what he was doing and walking over to her to wrap his arms around her. "That would be our dinner."

"Well good I'm starving." She said against his chest. "Why are you so giddy?"

"It's been a long day without you. I'm not used to it."

He separated from her and went back to making some stew.

"Now listen, I have something to tell you but please don't be mad."

This made Mikasa nervous and the way he presented it was absolutely terrible. Eren turned to gauge her reaction, adding suspense which only irritated her further.

"Spit it out already!" She hissed.

"Well I ran back into that girl from the other day and she started asking me a bunch of questions. But I had to respond!" He quickly added at the look on Mikasa's face.

"Oh really?" She asked folding her arms.

"Yes! Because she was saying that the people in town have been talking about us so I tried to qualm the rumors." He was getting desperate now because Mikasa expression was murderous.

"And do you think you did a good job of squashing any suspicion about us?" She asked trying to keep her voice calm but clearly bugged he had talked to another girl.

"Yes I do." Eren stated almost like he was talking to a military officer. "But moving forward your fake name is Rebecca."

Mikasa gapped at him in disbelief.

"Oh and we are married."

"WHAT?"

"Hey! I said what I had to, to get everyone off our backs."

"Eren..."

"I know, I know. But also look!" He said pulling out some chocolates he had gotten at the candy store as his trump card. "I got you these."

Mikasa looked at the chocolates and at the little boy look on Eren's face and knew she couldn't stay mad at him. After all, he had chosen to tell her about it right? He wasn't going to leave her for some random girl.

"What are the flavors?" She asked sighing.

Eren's face lit up and he placed all three in front of her.

"I wasn't sure what you would like, I just read in one of my books that girls like chocolate when they're feeling down. So I got one of everything. A dark chocolate, milk chocolate, and somewhere in between. And…." He paused as he turned to dig through their bags of stuff. "I got you this!"

He was holding a red scarf that was nearly identical to the one Mikasa had left behind. There was no shot that Mikasa was going to stay mad at him after that one.

"Eren!" She exclaimed, immediately grabbing the scarf and staring at in in disbelief. "Oh thank you so much! I really have been missing it so bad."

"I know you have. I see you reaching for it on your neck all the time. And now that it's getting cold it will really come in handy. I've been keeping an eye out every time we go to town, but today is when I finally found one that I thought was worthy to be worn by you."

Mikasa blushed and put the scarf on.

"So, how do I look?" She asked.

"Absolutely perfect."

The rest of the week was spent doing busy work, and of course, reading more books. Eren would occasionally try to make a move on Mikasa, but she was very adamant that she did not want to do anything until she was done with her period. Eren would always protest that he didn't care, to which Mikasa would reply that she very much did. So Eren painstakingly waited it out.

In theory, this shouldn't have been hard, but Eren greatly underestimated his sex drive. Its power over him scared him and he decided he was going to try and not let it control him. He committed to himself that he would focus on learning and reading unless Mikasa initiated. But there was a flaw in Eren's plan and that was that Mikasa also wanted him just as bad as he wanted her.

When at the end of the week, Mikasa walked out of her room with a big t-shirt on and nothing else, announcing it was finally over, Eren could have done a back flip. He wasted no time in having his way with her.

In the following weeks, Eren's obsession with learning was starting to get to Mikasa. She had gotten used to being the center of Eren's whole world, and she really didn't enjoy sharing his undivided attention with his books.

She would try to hint at subtle sexual advancements that he was too distracted to notice. On the rare occasion that he did catch on, he would willingly drop what he was doing, but the fact that she felt a need to make a move on him at all didn't sit right with her. Plus, the frequency of their intimacy was starting to dissipate. She was not used to him not throwing himself at her every chance he got.

Finally after almost two weeks of this, Mikasa decided to take matters into her own hands.

She had gone into town to sell some of their goods, and decided to go into an adult store and got something called lingerie. Walking out into the living room that night, she decided to initiate in a not so subtle manner.

"Eren."

"Mikasa! Hi!" Eren said looking up at her for just a second before turning back to his book. "Did you know that not only is the ocean salty, but it also produces the majority of our planets oxygen?"

"Ere-"

"And! Animals use the Earths magnetic field to know their location? Isn't it amazing to think that—"

"Eren!" Mikasa finally yelled.

Eren looked at her completely befuddled.

"Put down the book, and go to my room. I'll meet you there in five minutes."

Finally catching on, Eren practically ran to her room, throwing his book to the side.

Mikasa walked into the bathroom and changed into her new outfit. It was a black lace bra with a matching thong. She looked in the mirror and felt her breath shake with anticipation as she exhaled.

She wondered how Eren would react to it and if he would even like it? No. She didn't really care, because she felt confident in it. Him enjoying it would just be the cherry on top. Wrapping herself in a bathrobe, she exited the bathroom and walked into her room.

Eren was on the bed and before he could even register she had entered the room, she pounced on him. She grabbed at both sides of his face and started kissing him passionately as she crawled onto his lap straddling him in a sitting position. He immediately wrapped one hand around her waist to pull her closer and grabbed the back of her head with the other.

His hands traveled down to her bare legs and started sliding up her thighs until they slid out of sight and under her bathrobe. He held her hips and their bodies fell into the now familiar wave motion, grinding against one another.

Eren was feeling more slow paced tonight, and Mikasa wasn't having it. She was going to have him begging for her by the time she was done with him.

She pushed him down and stripped his shirt off. Eventually readjusting his position, Eren now lay on the bed with Mikasa on top of him. He felt the need to flip them over and start taking charge like he normally did, but right as he was about to make the change and Mikasa could feel it coming, she pushed his hands off of her.

"Not tonight. Tonight you're mine and I decide what we do."

"Okay." He said a little breathless. He reached up to her robe and started pulling it open suddenly feeling Mikasa was wearing far too much clothing. As he did so, he remembered she had just said she was in charge, and as if on cue, she slapped his hands away.

"You want to see?" She asked teasingly.

"Yes please." Eren begged.

She crawled off of him and in slow motion, she peeled the robe open to reveal her stellar body lined with the sexy lingerie.

"Holy shit…" Eren said sitting up on his elbows, pupils dilating so big Mikasa could barley see any of the green from his irises. "Where the hell?…." But he lost his words, too awe struck as Mikasa smiled and starting doing a spin so he could see the back side.

"I got it in town. Do you like it?" She asked, though his answer couldn't have been more clear.

"'Like it' is an understatement." He responded reaching for her and pulling her back onto him.

Mikasa squealed in delight, and they started making out again, Eren's hands running all along every ridge and seam of her lingerie.

He played with her hard nipples through the lacey fabric, and started massaging at her clit on instinct before she once again pushed his hand off.

"No Eren. I'm leading."

"Shit… fine." He groaned. He thought he had an idea that Mikasa's tactic tonight was to simply drive him mad. If this was her goal, so far she was doing an amazing job.

She pulled his pants down his legs and off his ankles giving zero attention to his erect dick, but instead started kissing him again and touching him everywhere except where he wanted her most.

She was slowly killing him. Right as he was about to ignore Mikasa's request to let her lead, due to the torture, she wrapped her lips around his tip and started circling it with her tongue.

"Ahhhh" Eren exhaled for what felt like the first time in minutes.

She deep throated his whole length a few times before abruptly pulling off of him and pulling her thong to the side. When Eren realized what she was about to do, he held his breath once more.

She lined her entrance up with his dick and slowly suck down onto it.

"Ahhh" Eren sighed again, eyes rolling to the back of his head at the warmth of her consuming him.

He grabbed at her ass cheeks to help ease her decent. She had never been on top before and as she bottomed out, she felt like his already huge length, was somehow even bigger at this angle. He truly seemed to fill every inch of her.

They sat like this for a moment, before Mikasa rose up on her knees, lifting off a few inches, before crashing back down.

The look on Eren's face was absolutely enthralling. She wanted more. So she did it again. And again. Faster. And faster. Until Eren lifted his hands from her body and grabbed at the top of the mattress, taking no care to suppress the sounds of his pleasure.

With Mikasa on top, her pussy squeezed his dick tighter than he was used to and too quickly, he was feeling close to climaxing.

He tried to think of something else and take deep breaths, but to no avail. Mikasa was too physically strong to be running out of energy any time soon as she rode him… he was gonna break.

"Oh shit."

They had, had sex enough at this point where sometimes one or the other wouldn't finish, so he was hopeful she would forgive him. Then he realized he wasn't in control and pulling out wouldn't be an option. Panic came over him.

"Mikasa!"

Immediately understanding, Mikasa stopped and bent down to kiss him. Allowing him to gain control of himself again.

After about thirty seconds, Mikasa started again. She was having a harder time feeling like she could come. Every once in a while, when she crashed her clit down just right against his pelvic bone, she could feel it, but she still had to find the right movement.

She tried making more of a wave like motion with her body as she rode him and started getting more surges of pleasure.

Eren didn't care what motion she did, he was so turned on he started feeling close once again. But with a little mind over matter he got to a point where he was okay for the time being.

Eventually he dared to open his eyes. When he did, he was met by Mikasa's breasts bouncing up and down as she rolled her body on top of his. But they were covered by her bra.

"Mmm that won't do" he said reaching up to her spaghetti straps and ripped them down hard, allowing her tits to spring free. "Much better." He said, that animalistic look Mikasa had been craving, glinting in his eyes.

With Mikasa maintaining her rhythm, Eren grabbed her tits and started sucking on one, squeezing the other. This helped. Mikasa could now feel pleasure surging and she knew she could get it soon.

Eren broke his lips free again to tell her he was close. She immediately stopped. Eren continued his assault on her boobs in the meantime.

This went on for a couple rounds. Eren getting close, Mikasa stopping and not allowing him to finish. He was starting to want it so bad, he felt uncomfortable in his own skin.

Mikasa found the control she had over him exhilarating. This man who, in every timeline, is the most feared and revered of any person in history, was right here. Under her, in her, and completely at her mercy. He was begging for her, crying her name. What a powerful feeling... She had him right where she wanted him.

After many minutes, Mikasa finally felt like she could climax. Eren was also once again at his breaking point.

"I'm close." She said.

"Does that mean I finally get to give in?" Eren winced.

"Yes."

"Hell yeah." He sighed. "But Mikasa." He said through bated breath.

"Yes?" She asked, arching her neck back not really paying attention.

"I can't pull out baby. You'll have to listen to my instructions closely."

"No."

Eren's eyes opened wide.

"What?"

"No." She repeated. "Inside." She said mouth hanging open, eyes closed.

"Are you serious?"

"If you want to come, it's in me or not at all…" Mikasa commanded. She felt a need to feel more of that power over him.

Normally he would have put up a fight, but after a night of being edged so brutally and for so long, he was ready to be her slave if she wanted him to. Of course he would obey her demand.

"Okay." He breathed, allowing himself to give in and let excitement take over. "I'm super close."

"Me too…" Mikasa moaned.

After a few more pumps, they both tipped over the edge at the exact same time. Mikasa reached down and gripped Eren's hand tight and pushed it into the mattress. The room was full of sounds of their collective screams of pleasure.

For the first time ever, Eren's cum shot up into Mikasa. At the same time, Mikasa's walls were spasming and squeezing his dick tighter than ever, as if trying to squeeze every ounce of sperm out of him and up into her womb.

"Mikasa!" Eren moaned, "Oh fuck, I love you so much baby!"

They rode it out as long as they could, never wanting it to end. But when it did, they looked into each others eyes. Eren reached up to her shoulders and pulled her down onto him squeezing her tight and staying connected inside of her.

"Damn. It's gonna be so hard to go back to pulling out after that... Mikasa… that was incredible. I think I like when you take advantage of me." He smirked looking up at her face. "Where did that come from?"

"I don't know." She said lifting off of his chest to look down at him. "I just knew I wanted you… really, really bad. Still do."

Eren could feel himself getting hard again just by the seductive look in Mikasa's eyes and her tone.

Could he really go again?

Yes. Easily.

This time Eren insisted they continue with Mikasa on top, but that she needed to turn around so that he could she her ass bouncing on his dick. She agreed. When she disconnected and his cum started dripping down her thighs, it turned Eren on even more.

Before she could put him back in, he grabbed the sides of her thong and ripped it off. She lined up and slid back down, riding him backwards.

All of Eren's efforts to not be so obsessed with fucking Mikasa came crashing down. He could do this forever. But only with her. She was the experience. He wanted to experience everything and every position that is possible. Multiple, multiple times before he inevitably died.

Suddenly, he felt the desire to have more. More than just the two of them. He wanted it all. He wanted her forever. He didn't want to die. Instead he wanted a token, physical proof that she was his and that he had, had her like this…

"I'm close." He said as his thoughts got the better of him pushing him to another orgasm.

"Me too."

"Inside?"

"Inside." Mikasa confirmed.

After their second orgasm, they were both officially exhausted. Mikasa got up and went to the bathroom as Eren stripped the ruined sheets. When Mikasa got back, they cuddled and started drifting off to sleep feeling perfectly content.

Naturally Mikasa fell asleep first, and she left Eren fishing through his emotions. He thought of the feelings he was having right before his second orgasm and tired to place where they were coming from. Then it hit him.

He wanted Mikasa to have his babies.

He wanted walking proof that she was his. He wanted everyone to know what they had done in this cabin.

But most importantly, he wanted to raise a family with her. Marry her. Grow old with her. And to love her all her life.

He thought of someone like Jean having all of those burning desires of his and felt light headed from how upset it made him. His heart started racing and his breathing became shallow.

He couldn't confirm or deny from his memories of the future if Mikasa gets over him and ends up with Jean, but his final conversation with Armin definitely messed him up and left him worried about it.

As real and as fair as these feelings were to Eren, he would never say a word of it to Mikasa. Because no matter how much it hurt him to imagine her like this with anyone else and someone else getting to grow old with her…

He never wanted to compromise her happiness again.
