A/N: Hey guys! So with the anime and recent manga chapters, I've gotten tons of inspiration for this story! So much Arthur! Aaahhh! It's great! So please enjoy this chapter! Oh and warning: There's some light smut in the beginning but I've marked where it is!

You and Arthur ran through the woods together, chasing a demon that had attacked Arthur's troops. Arthur instructed them to keep fighting as the two of you snuck through the woods to attack it from behind. A brilliant idea that you came up with. You ran up and jumped off of a hill and stabbed it in the back with your sword, piercing one of the hearts. It roared and turned and that's when Arthur attacked it from the front, stabbing another heart. The two of you worked together like this, each of you stabbing each of the demon's seven hearts and dodging it's attacks. Arthur kicked off of it as he stabbed the sixth one and it fell back. You ran up it's leg and made your way up it's chest and raised your sword, jumping off as it hit the ground and prepared to strike the last heart. You landed on his chest and were about to thrust the last blow into the heart of the demon with your sword but then you heard Arthur call out.

"Wait stop!" Arthur yells at you and you turn to him, concern on your features.

"What!? What's wrong?" You call back to him.

"I got a splinter." He says sheepishly and holds up his finger.

Cath smacks him in the face with her tail and you thrust your sword into the demon and roll your eyes but smile and walk over to the King who was looking at his finger.

"When we jumped down from the tree the branch I was holding must have brushed on my hand and pricked me." He says, tears forming in his eyes.

"Let me see Arthur." You say and take his hand.

You gently kissed his finger. Your lip brushed against the protruding wood and so you bit it gently and then pulled your head back, pulling it out of the King's finger. He yelped in pain but relief flooded over him when you spit out the splinter.

"All better?" You ask him and he nods eagerly. "Definitely! Slaying demons and healing my injuries, you're definitely the best girlfriend ever!"

You laugh as he picks you up and spins you around before giving you a huge wet kiss on your cheek.

"You handled that new heavier sword amazing!" Cath compliments.

"Yeah. It takes most Holy Knights years to build up the strength to hold up a sword of that caliber but you were able to do it in a week! You're so strong Y/N you're amazing!" Arthur fanboys and looks at you adoringly with hearts in his eyes. You laugh and kiss his cheek.

"Thanks Arthur." You tell him. "And thank you too Cath." You say as she jumps into your arms and you scratch her behind the ears.

"Oh you got it! That's the spot! Right there! Arthur she's definitely a keeper, she knows all the best spots to scratch!" Cath meows and swishes her tail happily.

"I know she is Cath." Arthur says and wraps his arm around your waist and brings you in close. "Trust me I'm going to do everything in my power to keep her at my side."

"Arthur..." You say sweetly and blush.

He tilts your chin up and brings his lips to meet your own, and gives you a sweet and passionate kiss.

"I mean it Y/N." He says seriously when you both pull apart. "I love you more than anything in the world. You're the only girl for me."

"Arthur..." You say sweetly and soon the two of you are making out with each other in front of the demon you just slayed together.

"Hey! Let me out of here!" Cath exclaims and wriggles in your arms. "I don't want to be pressed up against you horny teens while you're sucking each other's faces off!"

You and Arthur pull apart, blushing and laughing as Cath jumps out of your arms and shakes off her fur.

"You two are absolutely disgusting you know that! But at least Arthur isn't groping Y/N constantly like Meliodas does to Elizabeth." Cath says.

"Yeah I am thankful that my sweet Arthur is much more of a gentleman than Meliodas." You tell him and Arthur blushes.

"I mean I definitely want to grope you sometimes." Arthur admits. "But I'd never want to disrespect Y/N by just grabbing her without her consent. First of all it's totally wrong to do that and second of all I'd get slapped to Liones if I ever did!" He laughs and you smirk at him.

"Thank you my King." You tell him and walk closer to him. "I hold the same respect for you. But my adrenaline's still pumping from that battle." You tell him in a seductive tone and Arthur's face started heating up.

"Mine too." He pants.

He gasps in embarrassment when the two of you hear a small thud, which was the sound of his boner hitting his armor and he covers the area and smiles sheepishly and you giggle.

"No one's around, and we're not expected back for a bit longer..." You trail your finger down his armor. "Want me to take care of that for you?" You ask as your hand rests over his crotch gently.

"Yes." He breathes.

*Smut below*

You reach under his armor and stick your hand down his pants and grasp his hard length, causing him to let out a soft moan. More followed as you started pumping him in your hand.

"Oh my gosh Y/N that feels amazing!" Arthur moans and leans against you as you give him a hand job.

Suddenly you gasped as you felt Arthur's leg in between yours. He started rubbing it up and down your center, effectively turning you on.

"Arthur..." You moaned.

"You need to relieve some tension too don't you m'lady?" Arthur asks and you squeeze his cock and he moans. He looks at your chest and licks his lips. "Can I take your top off?"

"Yes." You say.

He lowers the chest plate on you, revealing more of your soft flesh to him and you felt his dick get harder from the sight. He reached out to stick his hands down the chest plate and grope your breast.

*Smut ends*

"So the battle went well?" Merlin asks from behind the two of you.

Arthur's head shot up and he immediately went soft and turned around, blocking Merlin's view of you so she wouldn't see what he was doing to you.

"Yes it went great!" Arthur says quickly and gave Merlin a nervous smile.

You roll your eyes and fix your chest plate before the mage. She noticed you and chuckled. She knew that sweet little Arthur wasn't so innocent anymore since the two of you had gotten together.

"I see that. It's a good thing you two took down this demon. I wouldn't want it hurting anyone else." Merlin says. "You've gotten a lot stronger as a warrior Y/N. I think that soon you may unlock your true powers."

The thought excited you and you smiled and ran up to Merlin and hugged her.

"Thank you so much Merlin!" You say and she smiles. "You're very welcome dear. Now I'm going to teleport you back to your room in the castle so that you can get ready for the ball tonight."

"Oh right! Arthur's birthday ball. I almost completely forgot." You say.

"I did too!" Arthur exclaims.

"How do you forget your own birthday!?" Cath barks at him.

"I've been busy! It just slipped my mind!" Arthur tells her and picks her up. "But you know I'm going to give you so much food when we're there you'll be full for a week!"

"Oh Arthur thank you so much!" Cath meowed and rubbed herself against him. "You're the greatest King ever!"

You smiled fondly at Arthur and Cath and Merlin laughed.

"See you at the ball Arthur." You say.

"I'll see you there m'lady." Arthur smiles and you disappeared.

Merlin walked towards Arthur.

"You need to prepare as well. But first you'll have to have a meeting with Lord Salem." Merlin explains.

"Ugh. What does that jerk want to talk about?" He asks.

"You'll find out." Merlin tells him and the two of them and Cath disappear and appear in the Noble's office.

"My King." Lord Salem bows to Arthur and he frowns at him.

"Lord Salem. You requested me. What do you need?" Arthur asks.

"Well first of all I would like to congratulate you on your coming of age today." Lord Salem says. "But there are other pressing matters at hand that come with that."

"Like what?" Arthur asks.

"You already know that you are now of age to take a wife." Lord Salem explains.

"Yes. And I have already selected my Queen." Arthur says. "If you're going to try to argue with me why I can't be with Y/N-"

"Quite the contrary actually." Merlin adds from behind Arthur and the King looks between his Mage and Noble with a shocked expression on his face.

"We are in a time of war King Arthur." Lord Salem informs him. "And during such a time, there is much death and insecurity amongst the people. As a King it is your duty to strengthen morale and give your people hope for the future...In the form of taking a wife, and more importantly producing an heir..."

"You want me to have kids?" Arthur asks.

"Yes." Lord Salem says. "Normally I would never approve of someone like Y/N taking the throne. She has no experience in politics and acts rather rashly for a woman." Arthur clenched his fist and growled. Merlin placed her hand on his shoulder to calm him. "But if anything were to happen to you then you need a blood relative who can take your place on the throne. So perhaps there is a use for Y/N. She loves you and you love her, therefore I suppose it wouldn't be too much to ask her to conceive a child with you as soon as possible so Camelot has an heir to the throne should anything happen to you." Lord Salem explains.

"So now you just like Y/N because she's someone I can impregnate?" Arthur asks.

"Well yes. That is part of the politics of being royal." Lord Salem says. "I thought you'd be happy. I'm giving you permission to have a child with the woman you love."

"Yeah but I'm not sure if she or I are ready for that yet." Arthur says. "I mean yeah I want kids but not so soon."

"We don't have time to wait. You need an heir now." Lord Salem says.

"But what about Y/N? Doesn't she have a say in this? It's her body it should be her decision." Arthur argues.

"Y/N has a duty to be loyal to Camelot." Lord Salem says. "If her King commands her to bear his child then she must obey." Arthur shivered.

"You're disgusting!" Arthur spits at him. "Y/N is not some baby factory she's a human being who's smart and strong and kind and is going to fight for her kingdom. She can aid Camelot in any way that she chooses. I would never force her to do something she doesn't want to do. I'll see you later." Arthur says and storms out of the room.

Merlin sighed and followed him.

"Arthur think about this." Merlin says.

"Don't tell me you agree with that pig?" Arthur asks.

"Trust me I hate the guy." Merlin says. "But he does have a point. You need an heir and Y/N can provide you one."

"I know but I couldn't live with myself if I forced her into something she didn't want. That's not fair to her. She wants to fight at my side she can't do that if she's pregnant. I don't want to take that away from her." Arthur explains.

"I know. Y/N will become a strong warrior, you will need her at your side on the battlefield and that's why I've come up with a plan that will satisfy both your needs and the kingdom's needs." Merlin explains.

That night at the ball Merlin stood by Arthur's side as he stood by the throne. He looked so regal, his golden crown on his head and his eyes fierce with love for his people. He smiled at all of them enjoying themselves. He laughed when he saw Cath gorging herself on food at the buffet. Then his eyes lit up when he noticed some snickerdoodles on a tray. He licked his lips and looked at Merlin. She was occupied drinking some wine and talking with the Nobles. So Arthur took this chance to sneak away and get some food. He looked around to make sure no one was looking then shoved one in his mouth, followed by another and another.

Then he heard everyone in the room go silent. He turned and his eyes went wide and the cookie fell out of his mouth. You had just entered the room. You wore a beautiful sparkling ball gown that was your favorite color. You looked so beautiful it was as if you were practically glowing. You were like a Goddess. He smiled and the crowd parted for him as he approached you.

"You look so beautiful." Arthur breathed, taking in the sight of you. "You look like a Queen."

"And you a King." You compliment and Arthur offers his hand to you.

You take it and gasps and murmurs started amongst the crowd. Arthur pulled you close to him and the two of you began to dance. It was like something straight out of a fairytale, dancing with the man of your dreams. You didn't even notice all the people staring at you. It was just you and him, no one else mattered. It was the two of you against the world. Just like it's always been. You rested your head against his chest and he held you close to him and the two of you stared into each other's eyes and saw everything you've ever wanted in them. You two completed each other. You were two halves of a whole and that's when Arthur knew it was time to ask you something very important.

"Come to the garden with me?" Arthur whispers in your ear.

You nod and the two of you sneak away together. He leads you over to a tree with a swing and has you sit down on it. He pushes you gently like he used to do when you were kids.

"Y/N what are you thinking about?" Arthur asks.

"How I never noticed you had a crush on me when we were kids." You tell him. He laughed.

"I wanted to marry you from the moment I laid eyes on you." Arthur admits. You giggle.

He stops the swing and you turn to look at him. He looked serious.

"I still do." Arthur says and your heart raced as he got down on one knee. "Y/N you are the only woman I've ever loved. You'll be the only woman who holds my heart. So now that I know you love me back I need to ask...will you make my dreams come true and marry me?"

"Yes!" You tell Arthur and he tears up and kisses you.

He grabs you tightly and kisses you passionately and holds you close.

"Oh Y/N I'm so happy to hear you say that! You're going to be the greatest Queen Camelot has ever had I know it! But there's something else too..." Arthur says.
