I don't own Merlin. (Sadly.)

Here is the sequel to 'Kingdoms united' (You are best to read that first if you haven't already:) ) I don't how many chapters it will have, but I do know it will have quite a few chapters.

Warning 1: Ygraine and Balinor are still alive. Warning 2: Uther will be ooc in this story (sorry if you don't like that) Warning 3: This will be malexmale. Warning 4: This will be Mpreg. (my first Merlin mpreg so bare with me :) )

All the spells that Merlin actually says in " " in this story are what Merlin says in the show :)

Thank you to cathcer1984 for your help :) x

I apologise in advance for any mistakes I may have made :)

As time went on, Merlin had started to show, Arthur watched with a smile on his face when ladies of the court would place their hand on his stomach and argue over who was right in guessing the sex of the baby. But whenever Gwaine would, instead of place a hand on Merlin's stomach, wrap both his arms around Merlin, Arthur would then step in and pull Merlin out of Gwaine's reach. "You are very easy to wind up Arthur. You ought to see him one time when he doesn't think you are there. He does it solely to wind you up and you fall for it every time."

"Can't he just be normal?"

Merlin laughed. "He is normal. He just goes into joke mode when he knows you are nearby. Anyway, I was talking to my mum this morning and she was asking how her grandson was doing."

"Another one who thinks it is a boy."

"What would you like Arthur?" Merlin asked as he wrapped his arms around Arthur's neck.

"I don't mind. As long as he or she is healthy and I still have you afterwards."

"What makes you think you won't have me?"

"Won't it be more dangerous with you being male?"

"A little. But my mother and father will be here three weeks before I am due and are staying for about two weeks after."

"Is it just this one baby we can have Merlin? I mean, does your father have to use that spell whenever we want a baby?"

"No Arthur. I simply take a potion until we are ready to become parents again."

"How is Merlin and my grandson doing?" Ygraine asked Arthur when they took to walking around the royal garden. "You as well? Why does everyone think that the baby is a boy?"

"Merlin starting to show now Arthur, and he is showing all on his front. Nine out of ten pregnancies, you carry the weight at the front, it's a boy, you carry the weight all around, it's a girl. When I was carrying you it was at the front."

"Yes but mother how many men have you seen pregnant?"

"Merlin is the first, but a pregnancy is a pregnancy. Merlin is carrying it all at the front. Your husband is carrying a boy. I'm sure of it."

Arthur smiled and kissed Ygraine on the cheek. "I'm going to go and check on Merlin. To see if he is actually doing what I asked him to."

"Which is what?"

"Resting."

"Before you go Arthur I should warn you. Within the next couple of weeks Merlin will be going hot and cold on you, he will be loving you one minute and snapping at you the next, even if you haven't done anything."

Arthur looked shocked at this piece of information his mother was giving him. "Why?"

"Mood swings Arthur. You want to know how best to deal with them seeing as you will be on the receiving end of them, ask your father."

Arthur nodded. "I will." Arthur smiled at Ygraine and walked away.

A couple of weeks later, Arthur was beginning to see just what his mother meant by Merlin going hot and cold on him. Arthur walked into his and Merlin's chambers and stopped dead when he saw Merlin, cuddled up to Gwaine, on their bed. "What the fuck are you doing on my bed with your arms wrapped around my husband?"

Merlin lifted his head from Gwaine's chest. "He is comforting your husband seeing as you decided to just dump him whilst you go off and do you own thing, wouldn't want me in your way would you. Only want me when it suits you. You really know how to make me feel loved. At least Gwaine here cheers me up which is more than could be said about you."

Gwaine lifted Merlin's arms from him and got off the bed and walked over to Arthur. "Sorry Arthur mate, I only came to see how he was. I got warned about the mood swings and I don't envy you one bit. In fact I wish you all the luck in the world." Gwaine gave Arthur a sympathetic look and left both Prince's to it.

Not wanting to risk upsetting Merlin even more in this mood, Arthur pulled out a chair and sat down and covered his face with his his hands, letting out a sigh as his head drop back. Arthur jumped when he felt a weight on his legs and removed his hands and looked in front of him to see that Merlin had straddled Arthur, his hands on Arthur's shoulders. "Arthur." Merlin purred.

"Yes?"

"I'm sorry for snapping. Let me make it up to you." he said and ground his hips forwards, causing Arthur to groan. "Is this the horny Merlin I am now seeing?"

"What do you mean?" Merlin asked as he buried his face into Arthur's neck, kissing, licking and biting the flesh there.

"Well what you just displayed then was the pissed off Merlin. What I am seeing now is very clearly the lovable and horny Merlin."

Merlin pulled back and stood up. "I am not having mood swings Arthur Pendragon. You left me earlier and I was angry because I wanted to spend my day with you. Me realising I was being too hard on you wanted to make it up to you."

"I'm sorry Merlin sweetheart I didn't mean it that way. Come here." when Arthur reached his hand out Merlin slapped it away. "You know what? Don't do me any favours." he said and stormed out, leaving a slightly confused Arthur behind. That's it. He would let Merlin cool off and find him later. Right now, he was going to look for Uther and get advice from him on how to deal with the mood swings.

"Father I need to talk to you." Arthur said as he walked into the hall, interrupting Uther's and Balinor's talk. "What's wrong son?"

"It's Merlin."

"My son is alright isn't he?"

"Oh he is fine Balinor. He is also horny, then irritable, then loving, then bad tempered."

Uther and Balinor shared a knowing smile. "Merlin is having his mood swings is he son?"

"If that's what you want to call them, all I did was walk into our chambers and he snapped, then he said sorry and acted all loving saying he wanted me, next thing I know he jumps from me, slaps my hands away, snaps at me and leaves the chambers."

"You have my sympathies son. I had all of this with your mother."

"I had it twice as bad with Hunith because she was carrying twins. And the thing is, the more I see how Merlin is, the more I see Hunith."

"What do I do. How do I talk to Merlin without setting him off?"

"There is only one thing you can do son."

"Which is?"

"Agree with them." Uther advised.

"No matter how absurd it sounds, they are always right." Balinor said.

"The only thing you disagree with is when they call themselves fat." Uther said with Balinor nodding his head in agreement. "Merlin would never call himself that and I wouldn't let him."

"He will start saying that he is fat when he is showing more. He will start to push you away."

"He will also say that he does not want to share the same bed with you-"

"Not allowed to see him naked anymore-"

"Won't even think about getting undressed in front of you-"

"Won't let you help him stand up as he will think he is too heavy."

Arthur was looking from Balinor to his father, his jaw dropping further at each new bit of information. "Are you serious?"

"Very Arthur. Just trust us with this one. You want peace and quiet, just keep agreeing no matter what."

"Except when they say that they are fat, if he enjoys the compliments you give him when he says he is fat he will do it all the more." Arthur nodded. "Okay. Thank you father. Balinor."

When Arthur left the room Balinor and Uther started to chuckle but stopped when they heard to female voices. "Just agree no matter what?"

"Anything to keep the peace?" Balinor and Uther turned to see their wives glaring at them with their arms folded across their chest.

:O Uther and Balinor have been caught out. Poor Arthur ;)

What do you think?

Chapter eleven will be up within a week :)
