Eren Yeager and Frieda Reiss had successfully prevented a disaster by defeating Warrior Unit before they reached the walls. Afterwards, Eren Yeager had turned the defeated Warrior Unit over to the Military Police Brigade where they would be restarined and interrogated by the Survey Corps.

Everyone within the walls had not the slightest clue of what happened. They continued to live their normal lives as usual. Especially Eren's mother, Carla Yeager, who was devoured by a Titan and became Eren's driven point into wanting revenge against all the Titans. Now that all the deaths had been prevented, history doesn't have to repeat itself and a young Eren Yeager is now able to go down a lighter path than his older counterpart.

On The Night Reiner Had Awaken

Due to revealing the identities of the Warrior Unit, an adult Eren Yeager and Frieda Reiss were relocated to Wall Rose to testify. Eren would solely testify to the courts and officials about the outside world and their lineage. Even revealing the secrets of his father, Grisha Yeager and admitting that Grisha is an outsider from Marley.

Later on that night, Eren and Frieda had settled down in a small apartment within Trost District. They unpacked their belongings and made themselves feel at home, until the Survey Corps. came to get them. The stars in the night sky shined, their was a crescent white moon.

Frieda Reiss had worn her long white pajama shirt and pink shorts. She sat at a desk and brushed her long black hair in a mirror for five minutes, until she heard the sound of a door opening.

"I'm back." Eren walked into their apartment to meet and closed the door behind him. He locked it as well, so people won't come in after them.

"Eren." Frieda had gotten up from the desk, sat down her brush and walked towards Eren. They hugged for a brief moment. "Did everything go well in the courts today?"

"It did. But I didn't think it would go on for almost half a day." Eren said.

"So... what happened?" Frieda asked.

"I told them everything I knew about Marley and the outside world. That we, even the Titans that roam outside the walls are a race called Eldians and are known as the Subjects of Ymir. I ratted out Bertoldt, Reiner, Annie and even my own dad to the courts." Eren told Frieda.

"It must've been hard for you to reveal your father's secrets."

"Not really. It took us five years to make it to his basement in Shiganshina. I thought it would be easier to get their, now, then back in my own timeline." Eren said, as he reminisced the moment when he had Grisha's secrets within the basement. "I haven't told anyone about you, yet."

"That's fair. I don't think I could present myself to that many people. I probably would have been nervous." Frieda blushed a bit.

"Don't worry. You'll do great one day. It'll take time, though. I'm going to introduce you to the Commander, tomorrow." Eren thought about Erwin Smith as he held both her wrists.

"Hm?" Frieda smiled, then looked at Eren's ears and noticed his ears weren't red this time. She giggled in front of him.

"What's funny?" Eren asked.

"Your ears. They're not red, this time." Frieda noted as she continued to giggle.

Eren remained silent as Frieda continued to giggle for a moment. He then walked Frieda towards the bed in the apartment and sat her down. He stood in front of Frieda, as she slowly stopped giggling.

"What are you doing, Eren?" Frieda asked, as she giggled less.

Eren began stripping from his clothing in front of Frieda. He removed his shirt and pants, revealing his muscular body towards Frieda.

"Uh?" Frieda stopped giggling all together as she witnessed Eren's figure. A big red blush appeared on her face, as she felt flustered. Her light blue pupils had gotten smaller. "E-Eren! What are you doing?" She quickly covered her eyes with her hands.

"I'm going to take a hot shower." Eren told Frieda, before turning towards the bathroom door and removing his boxers. "Feel free to join, if you want." Eren closed the bathroom door.

Frieda continued sitting down, blushing and covering her face. The sight of Eren's muscular figure had completely filled her mind, as she couldn't think of anyone else. After a minute, she heard the sound of a running shower let out a depressing sigh.

For the next three minutes, Eren bathed within the shower, alone in the nude, with nothing but a pink bar of soap in his hand. He rubbed his skin with the bar of soap and did not touched his man bun, as he wanted it to stay the same. As he was bathing in the shower, the bathroom door had opened up, sixty degrees. Next thing he knew, he felt someone making physical contact with him. Eren could easily tell who this was, by the touch of the person.

"Frieda..." Eren chanted.

"Hi, Eren." Frieda said in a soft tone. Frieda lied her head upon Eren's upper back and her hands rested on the back of his upper shoulders. Her hair was wrapped in a bun, as she didn't want to get her long black hair wet. Eren tried to turn around, but Frieda stopped him. She felt like he wasn't ready to see her nude body.

"Don't turn around." Frieda said, as she blushed.

"What's wrong, Frieda?" Eren asked, as he slightly turned his head towards the left.

"Nothing. I'm just... shy." Frieda replied, then shivered a bit. "I never showed my body to a boy, before..." She looked down at the floorboards, as the water went down the drain.

"It's alright. I won't laugh, or make fun of you or anything." Eren responded. A moment of silence occurred. "Can I turn around now?"

"Can I wash your back, first... for at least a minute?" Frieda made up an excuse for Eren not to see her. Then she grabbed a yellow bathing sponge.

"Alright." Eren easily replied.

Frieda gulped, then used the yellow bathing sponge to clean Eren's backside. She rubbed his back for a whole minute and then spent an extra thirty seconds.

"Frieda?"

"Yes?"

"I think it's been over a minute. Not to be rude." Eren said feeling patient.

"Oh, sorry. I lost count." Frieda apologized, as she knew it was Eren's turn to wash her body.

"I'll be gentle with your body." Eren said.

Frieda sat the yellow bathing sponge down the counter. "Okay." She covered her breasts with her arms and looked downwards and blushed a bit.

"Okay." Eren turned and looked at Frieda's backside. "Here goes..." He grabbed the yellow bathing sponge and stared at Frieda's backside.

Frieda stood still, crossing her breasts as Eren had taken the sponge and bent his knees. As soon as the yellow bathing sponge touched Frieda's skin, she let out a light gasp. She tried her best to stay still and not to let out more moans and gasps as Eren rubbed her back, up and down with a sponge. Part of Frieda enjoyed the soothing touch and sensation of Eren touching her skin as he washed her backside. Part of her wanted her to keep going, like she was floating towards heaven, spiritually.

"Done. It's been a minute." Eren said, after he finished washing her back with a soapy bathing sponge. "Feeling better?"

Frieda gasped after Eren stopped washing her body. "Oh." She paused as could feel something surging inside her body, causing her to get erected. Her back was still turned and she wanted to feel that same sensation again. "Um... Eren?"

"Yeah?"

Frieda slowly turned around and met Eren's green eyes as she smiled and blushed. "C-could you... wash my front side, now?" Frieda slowly removed one arm from her chest at a time, before showing her breasts to him.

Eren stood still and blushed at the sight of Frieda's front figure, head-to-toe. He looked into Frieda's light blue eyes, which were gazing at him and smiled. "Okay." He used the same sponge and rubbed from her chest, all the way down to legs.

"Ah..." Frieda moaned.

As Eren was bent and washed her womanhood, he heard her moaning out of pleasure. He slightly looked up and caught Frieda feeling on herself by rubbing her left hand down her side and grasping her left breast with her left hand. Her eyes were closed and her mouth was half way open. He slowly bent back up and faced Frieda.

"You like that?" Eren teased.

Frieda lightly nodded.

'That look in her eyes. She's asking me to take her.' Eren could see the love in her light blue eyes and that they were telling him to take her. 'But, what the hell...' In his mind, he simply shrugged. In reality, he grabbed Frieda by the hips, brought her closer to his body and locked lips with her. His tongue was deep within her mouth and his eyes were closed.

Frieda responded by kissing him back and wrapping her arms over his shoulders. She enjoyed every kiss, every touch and the shower waters pouring on them. She stood on her tippy-toes to kind of reach his height.

Eren used his masculine hands and gripped her soft feminine ass, earning moans. In his mine, he noted it to be as soft as a bed pillow. Frieda jumped off her feet as Eren caught her in the shower. She wrapped her legs around his waist, as they continued making out in the shower.

A few minutes of making out within the shower had passed, and now they are both nude in the bedroom. The lights in the apartment were out, the moonlight shined onto the both of them through the window. Frieda's long black hair was loosened from a bun and she sat on her butt on top of the bed.

"Are we about to do it?" Frieda asked as she smiled.

"Yeah." Eren blinked, then grabbed her shoulders and kissed her lips for a brief moment. He laid Frieda down onto her back and her head rested on a soft pillow. The moonlight shined on her naked body through the window, making Frieda look more pretty to Eren. He climbed on top of the bed and crawled over Frieda's body. They gazed into each other's eyes, lovingly.

As they stared, Frieda used her feminine hands to reach behind Eren's ears and ran her hands through his bun, stroking it. She wrapped her arms around his neck and smiled. "Your bun is nice, by the way. It just need a bit of a makeover."

Eren cracked a smile. "Does it..."

Frieda chuckled. "It does." she teased.

"Oh yeah? How about I give you a makeover, instead!" Eren said before teasing her with kisses on her face.

Frieda laughed as Eren attacked her face with kisses. "Eren, that tickles!" She said as she felt Eren's kisses go down from her face, to her neck.

He sucked on Frieda's left collarbone with his teeth for a moment. He put no pressure on his teeth as he sucked. He moved downwards her, planting kisses onto her upper chest. Eren moved his head up an inch and moved down to her breasts. He planted a kisses on her left breast and begun sucking on the pink nipple. This would earn a little moan from Frieda. As Eren used his mouth on Frieda's left breast, he hadn't forgotten about her right. He used his strong left hand to massage it, romantically earning a few moans.

Frieda moaned as she was feeling pleasure from having Eren work on her breasts. She could feel his hot tongue circling around her left nipple, and his left hand stoking her right. 'How did Eren get this good...' Frieda thought, as she let out feminine moans. After ten seconds, Frieda felt something pinching her nipple. "Eek!" She jerked as she felt pressure on her left nipple. She looked at down at her body, seeing Eren lightly teeth on her left nipple. "E-Eren! Don't bite my nipples!" she blushed, feeling a bit embarrassed.

"Sorry. I didn't think you'd feel that." Eren apologized to Frieda, before going back down kissing her nipple.

Frieda giggled. "Can I also get one up here?" Frieda pointed at her mouth with her index finger.

Eren moved his head in front of Frieda's face and delivered a nice kiss to her lips. Then he moved down to her stomach and gave it three kisses, before sticking his tongue and licking her navel for a brief second. He licked down to her vagina, where Frieda's body would begin to feel hot and her brain would feel a little warm.

'Eren...' Frieda moaned in her mind.

Eren felt something erect while licking her vagina. He sat up on his knees and looked down to see his cock fully erected. He looked at Frieda's body, which looked pretty in the moonlight. He stopped for a moment and looked at Frieda.

Frieda suddenly noticed Eren stopped tongue stroking her vagina and looked to see Eren sitting under her. "What's wrong?"

"I know this is your first time, so I'll try to make it as painless as possible." Eren said as he used one of his hands and positioned his erected cock to penetrate Frieda.

Frieda stared at Eren's cock for a moment, then nodded at Eren. "Okay."

"Are you sure you want to do this?" Eren asked, partially hoping that Frieda would back down.

"I made it this far. I'm not backing down, now." Frieda said with a bold face, as tiny orbs appeared in the corners of his eyes.

Eren saw the bold look on her face and knew she was serious. Then proceeded to slowly enter the tip of his cock into Frieda's vagina. Eren gripped her hips so she wouldn't squirm around. Frieda grunted and bit her bottom lip, as she can feel the tip of his cock inside her. She tried to hold back the tears while Eren was moving into her.

Eren could see the look of small pain on her face, and the cry as well. He knows that Frieda's trying to hold it in. He knew that Frieda didn't like pain, as he started counting in his head. 'One... Two...' and without warning. "Rrgh!" Eren grunted and rammed his cock deep in Frieda's vagina.

"Aaah!" Frieda screamed in pain and in agony as tears quickly streamed down her face. Blood had ejected from her vagina and onto the sheets, meaning that she was a virgin.

As soon as Eren thrust within her, he groaned as he felt a ton electricity surging within his body, like he was being charged with power. 'Dammit! This energy I'm feeling... it's like I'm being charged with power!' Eren noted as he grunted from the stings.

Frieda on the other hand was screaming from the pain and had small sparks of electricity her face. She seemed like she was about to transform into a Titan, as her eyes begun to flash.

Eren gasped as he saw the electricity spark around her face and her eyes begun to flash. 'Oh no!' Eren knew what this meant, and if he doesn't stop her, Frieda would destroy the entire apartment. He quickly pressed his lips against hers and massaged her left breast, calming her down from the pain and to hopefully stop her from transforming into her Titan form. 'Fight it! Fight!'

Luckily, Frieda had calmed down in less than a minute and the electrical sparks had disappeared, completely. She responded by kissing him back again while under him. Their tongues had locked and battled each other in dominance in the next twenty seconds. Eren had won in dominance once again, and kissed Frieda romantically.

"I'm sorry." Frieda said after breaking the kiss. "I almost transformed by accident." she said wiping a tear from her eye.

"It's alright. I tried to make it painless." Eren slid his right hand from her left neck, to her cheek.

"She we continue?" Frieda asked.

"Do you want to continue?" Eren replied as he looked at her, while still inside her.

Frieda placed her left hand over his right hand, which was on her left cheek. She looked into Eren's green eyes and smiled. "Please, continue." Frieda nodded.

"Okay." Eren took his left hand and gripped on Frieda's right hip while on top. "Here goes nothing." They connected their other hands which was on Frieda's cheek as they continued sexual intercourse. Eren moved his hips forward and thrust within Frieda, causing her to rock a bit.

"Ah... ah..." Frieda moaned, letting out gasps as Eren would go deeper inside of her. A blush appeared on her face, as she felt warmer and warmer inside her lower body. Her right hand gripped the bedsheets to have something to hold onto. Two minutes of thrusting, Eren started going a little faster, which Frieda realized. "Eren... go faster... faster!" she moaned and pleaded, while Eren continued thrusting.

He went faster like Frieda asked and noted he was about to burst. "Frieda! Get ready!" Eren yelled, warning Frieda that he was planning to ejaculate his semen inside of her womb. "I'm about to-"

"Me too, Eren!" Frieda yelled, as electrical sparks appeared around her body.

"Let's come together!"

"O... okay!" Frieda leaned her head forward and kissed Eren before ejaculating.

"I'm going to come, now!" Eren yelled, as he reached his breaking point. The tip of his cock was brushing against her womb, nearly reaching the egg.

"Me too! I'm about to come right now!" Frieda screamed.

"Try not to transform or activate the rumbling!" Eren instructed while reaching his limit.

Fifteen Seconds Later

Eren had squirted, unleashing the semen out of his body and ultimately ejaculated inside of Frieda Reiss. It was like a large body of water escaping a partially broken dam.

"Ah!" Frieda screamed, as she felt Eren's load of semen squirted inside of her. It was like part of a dam breaking apart and water had been released inside her. Frieda's eyes were filled with lust and had caught an orgasm. Her face had turned to a light shade of pink as she was filled with Eren's-so called Love.

Meanwhile, in Shiganshina District, a ten year-old Eren Yaeger had woken up from his bed in the middle of the night, panting and sweating. Feeling all hot. He looked around in his room, left and right to see that no one was there. He looked down at himself and gasped to see that he peed in his pajama pants. "Argh, dammit! Not again!" Eren felt embarrassed, peeing in his own clothes. He quickly rushed towards the bathroom from his room, so that his mom and Mikasa wouldn't find out. He quickly closed the door behind him, too.

Meanwhile, in Orvurd District, Rod Reiss was sleeping in his bed with his wife. He slept in his white pajamas and was having dreams about spending time with his family, excluding Historia, until he felt an electric spark. He had suddenly remembered his eldest daughter, Frieda.

"Frieda!" Rod Reiss yelled, as he woke up from his dream, remembering his eldest daughter. He panted in his bed and looked around to see no one but his wife sleeping in the same bed he is.

Rod's Wife slept on her side and heard noises from her husband. "W-what?" she asked, while rubbing her eyes and waking up from her slumber.

Meanwhile, in Stohess District, part of the walls had begun to crack. It had revealed part of the face of a Fifty-Meter Titan. It had stood still in place within the walls, refusing to break free.

Meanwhile, Grisha Yaeger had already left Stohess District and was riding back to Shiganshina on a red horse carriage, after finishing with a few patients in the interior. While riding, he had suddenly sensed something or someone far too familiar. He looked directly at the night sky and thought of someone. "E... Eren?" Grisha questioned while riding the red horse carriage.

Meanwhile, from all the way in Marley, a twenty year-old Zeke Yaeger was in a bathroom brushing his teeth in front of a mirror, until he felt a weird sensation. He gasped and dropped his toothbrush in the sink and looked around in the bathroom. "What was that just now?" He asked himself. Then he clasped his own head in front of a mirror. "That's weird... I could've sworn I've sensed someone familiar."

Meanwhile, back in the apartment within Trost District, Eren and Frieda lied next to each other within the sheets. Eren lied on his back and Frieda had lied on her right side, clutching on Eren's left arm She lied on Eren's left. They both panted a bit and lied in bed under the crescent moonlight, after finishing their intercourse.

"Eren..." Frieda said in a soft tone.

"Yeah?" Eren's eyes moved to look at Frieda.

Frieda leaned the right side of her head up from a pillow. "You're actually an amazing person, aren't you?" She looked at the crescent moon through the window and noticed how pretty it was. "For years, you wanted to see what was it like on the outside world, and you didn't let anyone stop you from getting there... and now that you went back in time, you've given your younger self a chance to have a better life."

"Yeah." Eren replied.

"Think about it. You went back in time, you found and freed me from the "Vow of Pacifism" a few days ago, introduced me to your parents and now we saved everyone that died in your timeline within the walls, including your mother. That's amazing!" Frieda smiled at him. "And now if Marley come and attacks, we can make it."

"Frieda..." Eren turned his head to Frieda, catching her attention. "Let's get married." he said, plainly while lying down.

Frieda lied back on her side and chuckling to Eren. "Eren... you have to give a girl time to think it through. We girls do want to get married, someday, but not the next day." she said, feeling all positive.

Eren sat up in the bed. "So, is that a..."

"Yes," Frieda sat up, meeting Eren's gaze. "I do want us to get married." she smiled and blushed.

'Frieda...' Eren cupped Frieda's right cheek with his left hand and kissed her lips. 'I want you to stay by my side. Forever. Even if I have four years left to live. I want to spend it all with you.' Eren and Frieda continued making out for the rest of the night.

Author's Note: Thank you for your patients. It took me a while to think it through and make it this Lemon. I always wondered what would happen if two Titan Shifters had mated? So I tried my best to make this.
