Summary: All is going well at a party, that is until Merlin accidently drinks Gwen's fertility drink before making his moves on the one he is too shy to when he is sober, his best friend and flatmate Arthur.

Warnings: Angst, AU, Mpreg, malexmale. Merlin has magic

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

Merlin woke up with a bad headache, he reached out to pick up his phone to check the time and ended up pushing it off the chest of drawers and onto the floor. "Ugh" he moaned as he blearily opened his eyes, he wasn't going to drink again, no matter how much Arthur smiled at him with those perfect white teeth of his. He opened his eyes and looked around on the floor, finally locating his phone he picked it up and saw it had just gone ten in the morning.

He groaned when he heard a banging sound on the door to his and Arthur's flat. "Okay okay I am up and coming, hang on." he called out as loud as his head would allow him to, he walked out of his room and over to Arthur's and saw his roommate fast asleep flat on his front.

Moving over to the door he opened it to see Gwen and Lancelot there, smiling he let them both in.

"Did we wake you Merlin?"

"No Gwen I was just getting up when you started to knock, keep it down though, Arthur is still asleep and he had more than I had to drink last night." he said, wincing as he sat at the kitchen table.

Lancelot frowned at his friend. "Merlin are you alright?"

"Got a bad hangover, I am never drinking that much again."

Gwen smiled. "Well at least you had a great time."

Merlin yawned. "Yep, ugh all this magic and nothing will help my hangover. Why did I have to drink? I started out drinking your healthy protein shakes you keep on at me to drink Gwen but then Arthur insisted as it is a party."

Gwen frowned. "Merlin I didn't have any protein shakes in my fridge last night."

"You did, only one though, didn't taste very nice though, mind you I suppose they shouldn't really."

"Merlin mate where in the fridge was it?" Lancelot asked.

"On the fridge door." Merlin said, yawning once more.

Gwen gasped. "Merlin no! That wasn't a protein shake that was my fertility potion as me and Lancelot are trying!"

Merlin's eyes went as wide as they would go. "What?!"

Lancelot looked worried for his friend. "Will you be alright? Especially it mixing with your magic, I mean you are not an ordinary bloke are you."

"I don't know..."

"So you can get pregnant if you have sex within forty eight hours of drinking it?" Gwen asked.

"With how powerful my magic is I could do." Merlin sighed. "I don't know."

"Well as long as you don't have sex within forty eight hours of drinking it you will be fine." Lancelot said, smiling as he clapped Merlin on the back.

Merlin sat frozen to the chair, his mind going back to the previous night.

Flashback

Merlin shuddered as he downed the protein shake. "How does Gwen drink these time after time?"

"Forget them Merlin, have one of these."

Merlin turned to see Arthur stood there with two bottles of beer in his hand.

"I am not drinking a lot Arthur, just the one and that's it."

"Whatever you say Merlin, come on, lets go and congratulations the happy couple on five years of marriage."

"Oh I know, when they married at twenty I thought they were too young and moving too fast but they seem stronger now than they were then." Merlin added as he took a drink of his beer.

As the party went on so did Merlin's drinking despite him saying he was having just the one, he blamed his mates for that, every time his bottle of beer was empty all he heard was. "Nearly drank it? Here let me get you another." and a full bottle was placed in his hand and the nearly empty bottle was taken away.

Merlin after falling over the coffee table and landing at a laughing Arthur's feet decided to drink no more, it was one thing tripping over everything, he had any more to drink he knew what be coming next, flirting with anything that has a pulse.

"Just made a fresh batch of punch, all fruit juice so you are fine Merlin." Gwen called out as she placed the big bowl down.

What Merlin had failed to notice is Gwaine who always wanted a night with Merlin and knew what he would be like after drinking had poured some vodka in the fruit punch.

Merlin clumsily poured himself a big glass and drank it all in one go. "Oh that's nice, cheers Gwen." he called before stumbling and dropping his now empty glass making it smash. "Sorry Gwen."

After a few drinks out of the bowl Merlin had found his target to flirt with, smiling he made his way over to his roommate and decided to grab his arse and squeeze to get his attention.

Arthur jumped when he felt someone squeeze his arse and turned, smiling to see Merlin there. "What's up Merlin?" he slurred.

"I'm horny, there is a bedroom free, how about we use it, I need someone's cock in me and I have decided it is yours I want."

Arthur hummed as he looked Merlin up and down, "your magic isn't going to go crazy is it when you come, still remember what happened to that poor last bloke you slept with."

"No, my magic is fine, and he was only scared as he didn't know I had it, you do, come on I am horny." Merlin moaned as he grabbed Arthur and pulled him into the nearest bedroom.

End Of Flashback

"Merlin?" Lancelot asked. "Merlin what's wrong?"

Merlin closed his eyes. "I had sex with Arthur." he sighed.

What do you think?
