Chapter one: Promise me

HIDDEN

After the Survey Corps reclaimed Wall Maria, the refugees from Wall Rose went back to fix their old homes. The Survey soldiers were praised by the people as heroes. The newly crowned Queen Historia gave medals for their heroic act. While the queen handed out the medals to the surviving soldiers one by one, the crowd cheered. Once the ceremony was over, everyone mingled to congratulate the heroes. Captain Levi Ackerman was among his subordinates when a servant tapped his shoulder to get his attention. "Tch, yeah?" He looked at the servant who nervously handed him a letter with a royal seal. This made the captain turn his body facing the servant and took the letter. He opened the letter to read it. His eyes glance back at the servant. "Lead the way to Her Grace." Levi whispered. The dark haired man followed the servant to a hallway then made a turn to a double door and opened it to see the queen already waiting for him.

The servant closed the door from behind him to give privacy to both of them. Now, it's just Levi and Historia alone in the room. "Already missing me, Historia?" His smirk spreaded from his lips. Historia glanced at the short man as she got up to walk toward him. "You could say that." She giggled while her arms wrapped around his neck to lean in for a sweet kiss. Levi smiled then kissed her back as his hands gripped on her hips. The kiss became intense and passionate. Both lovers moaned from the pleasurable kiss. Historia pulled away to gasp for air. Levi admired her flushed face. The lovers had been together since Historia was known as Krista Lenz. The downside of their relationship was kept a secret to everyone since he's a captain and Historia is a queen. "Tch brat, you should be careful not to summon me alone. People will begin to suspect us." He caressed her beautiful angelic face. "I know but I missed you since we said goodbye before you head off to reclaim Shiganshina. I should have gone with you guys." Levi interrupted her. "No. I would have not let you even if you're stubborn enough to try to go. I won't hesitate to tie you to a chair and have you stay put like a good queen." he glared at his lover which Historia sighs but blushed at the idea of being tied by her boyfriend. "I love you. I can't bear to lose you, Historia." His tone was soft. The queen nodded. "How do you think I felt when you went on the recent mission? I spent those days feeling anxious and scared that you won't come home….to me. Neither could I lose you, my love." A few tears fell from her eyes when those days during the mission, Historia was feeling anxious like hell.

Levi stayed quiet, but he began to wipe her tears again. Historia grabbed his hand to leave kisses. She continued speaking. "I felt useless just having to wait at the palace while you and my friends are out there risking their lives. I should have been there to help. I was once a soldier! I am strong, Levi" She stared into the man's grey eyes. Levi sighed as he finally broke his silence. "Like I said, I won't let you. I lost the important people in my life before. Yes, eventually I moved on, but with you it's different. You're the first woman I fell in love with, and I follow you to death, if anything happened to you." He vowed to her. This is unexpected for himself since Levi never had been in love before. Now, he knows why some people did some crazy shit for love. Levi is known to take it extreme. He'll sell his soul to the devil if it saves Historia. That's how much she means to him. "You will certainly not follow me to death. I forbid you." She made her stand. Levi on the other hand, gave a dark chuckle. "You forbid me? Sorry you're majesty, but I already made an oath to you and myself." Historia sighed and thought about telling him the news she received when he was at the mission to reclaim Wall Maria. "Please Levi...if anything happens to me. You must live. You're humanity's Strongest." Levi scoffed. "That title means nothing to me besides, humanity got Yeager and Ackerman. Why do you want me to keep living?" He raised his brow at her curiously. Historia looked away nervously. She had been trying to find a way to tell him. How will he react? Will he hate it and walk away from her? "Because my greatest fear is to leave our child orphaned. If one of us died, he or she would need you." Her tone started to be shaky. Levi at first seems confused about a child that hasn't been born. Then he looked down to see her belly which it all clicked. "You're pregnant, aren't you?" His tone gave off monotone. "How far along are you?" He doesn't know how to take this news. Levi never considered having children even for the purpose of passing on his gene to the next generation. Levi was raised by Kenny Ackerman after his mother died. He doesn't have fatherly traits. He's worried he'll screw up the unborn kid.

Historia could tell Levi is trying to process what she said. "I'm 2 months along. I found out when you went to battle to claim back Wall Maria from the titans. I know this baby is unexpected, but we both can do this. We can raise this baby together. Our child will get the childhood we both didn't get." Historia's hands were placed on both of his cheeks. Levi sighed and continued looking down on her belly. "I can't promise to be the greatest father, but I will be there for you and our unborn. Beside, our brat will need to be trained to survive since it would now become an Ackerman tradition." Historia felt at ease since Levi accepted her pregnancy. "I don't mind it. There are people who will harm the baby because it has both royal and Ackerman blood in its veins. Promise me Levi that you will live to be there for our child. Promise me." Her eyes looked pleading which Levi placed his hand on her belly. He can feel a tiny bump forming. "I promise to you if you die, I'll protect him or her." He made a vow to his lover. Historia leaned in to kiss him again. "Thank you, Levi." She was now at peace. Their baby will be alright. She pulled away to admire his face. "So what now?" Levi was whispered. The queen was lost in her thoughts. "I guess we'll have to go back to the ceremony party. They are probably wondering about us." She was about to walk to the doors, but Levi grabbed her wrist to pull her back to him. "Let them worry. I've counted days to get to see you after the battle with the titans. I missed you so fucking much." He wrapped around his arms on her waist. He buried his face on her neck then kissed softly. Historia moaned softly and gripped on his shirt. "We'll stay 10 more minutes." Her moans were becoming frequent. Levi smirked and listened to how her moans were the most beautiful thing ever. Only he got the privilege to hear them. Only he will listen to them. She is his and he is hers. Now his lips hovered from her neck to her ear. "Let's get married. I want you to be mine forever." Historia was speechless at his proposal. "How are we going to pull that off?" She was concerned for the both of them. "One of the priests will discover our secret." Levi intervened. "Fuck them if they dont' like us being together, they'll have to get use to it. With you carrying my child, I think our relationship will be public soon." Historia nodded at what her boyfriend said. "We can just have few people knowing about us for now." He continued. The queen looked into his eyes. "Alright, we can tell a few people. I was thinking of Commander Hange and your squad. I trust them with our secrets."

Levi nodded in agreement. "We can tell them tonight since they will be our witnesses of our upcoming marriage." HIstoria smiled at him. Now it's her turn to lean into his ear. "I'll give 5 minutes extra." Her tone was soft but seducing. This made Levi arousal. His hand caressed her curve line which it sent shivered toward the queen. "Take me Captain. Please." Her begs are what drove him crazy. His eyes became lustful. A growl escaped from his lips. "Your wish is my command, your grace." he smirked which Historia blushed. Levi lifted her up as Historia wrapped her legs around his waist. He carried her to the table. Instinctively, the blonde haired woman sat on the hard surface. She hiked up her dress as her legs were spreaded. Levi took this opportunity to slide his under the dress and noticed she wasn't wearing anything under. "Oh what a naughty queen you are?" He chuckled while rubbing her clit slowly. "Mmmm oh Levi s-stop t-teasing m-me." Historia started panting hard. "Please please take me." She continued moaning and begging for her lover. Levi unbuttoned his trench uniform then his free hand undo his pants. His cock was pulled out to position between her legs. As he slid his cock into her wet pussy, Historia let out a small squeal, but her hand covered her mouth from concealing more sounds. Levi didn't give her time to adjust his size. She was used to his roughness and she loved it. The man's hips were thrusting roughly into her. The queen laid on the table once pleasure was starting to consume her. Her boyfriend increased his pace faster. Her eyes rolled back when Levi hit her sweet spot. Her back arched. Historia wanted to moan loudly his name, but they would get caught. He kept going faster until both had reached their climax. "Oh god Levi, Levi!" Her screams escaped but the captain covered her screams by kissing her roughly. She returned kissing him roughly as well. Both finished off by orgasm. Levi usually pulled out to spread his seeds on her belly, but it doesn't matter now since she's pregnant. He remembered two months ago, both of them were having a conservation while sipping wine. With them being drunk, they fucked like bunnies. Hell, they broke the bed. He doesn't know what Historia said to the maids when they discovered her bed broken.

After their quickie, Levi helped his queen to clean her then she fixed herself up to look presentable. Levi had cleaned himself and fixed himself as well. "You know the drill. You go first then I go later." He turned back to Historia. She nodded. "Alright, but I will see you tonight to tell them." She said and walked to the doors to carefully open. She made sure no one was there as she exited and closed the doors. The queen heads out to the party. Levi waited for 10 minutes as he exited then had the doors closed. He began to walk away to be with his fellow soldiers. A figure stuck his head out to watch Captain Levi and Queen Historia leaving the room one by one. His expression was in disbelief from what he saw and heard. Captain Levi? Historia? Together? Having a baby? What did he just hear? The figure run his blonde hair to try to process this shocking news. He doesn't know whether to tell the Commander about this. The young soldier decided to keep this secret to himself since it's definitely not his business to tell. He went back to the party to hang out with his friends, Mikasa and Eren.
