This is just a small Modern AU of Merlin x Arthur. A simple one shot based on Arthur and Merlin being a couple and Arthur proposing. I hope you enjoy it.

SUMMARY:Merlin and Arthur have been together since high school and now Arthur thinks it is time to take the next step in their relationship, marriage. The only thing is that Arthur is a little nervous about whether or not Merlin will say yes. But he plans to make it unforgettable for Merlin. (There is a sex scene! BxB! Just WARNING!)

PART 1

Waking up in the arms of the man you love is something I want to do every day of my life, being by Merlin's side always made me happy, I don't think there has been a single time when I have seen him and not smiled when thinking he is mine, he is really mine. When I think those thoughts I can't help but want to pull him into my arms and take him, show everyone that he is mine and nobody else's.

Kissing Merlin's head I smiled at the thought of the night ahead we had. Today was our 5 year anniversary of dating and tonight was the night, I was going to propose and ask him to be my husband. I wanted him with me forever and nothing was stopping me. I had the night all planned and I had been planning this for weeks so I hope it went well. Deciding it was time to wake Merlin up I kissed his cheek and whispered

"Merlin?" He moaned at me so I kissed lower and again said "Merlin, baby." He moaned louder and snuggled deeper into his pillow. I slipped my hand down his body and gripped his man hood and pumped him. His eyes flew open and said

"Arrh Arthur." I smiled and said

"Morning." He frowned and said

"Arthur why did you wake me up, I was having the best dream." I continued to smile and asked

"And what was this dream?" He sighed

"You were blowing me." I bit my lip

"Well since it is a very special day I shall make that dream come true." Before he could say another thing I was under the covers and had my mouth wrapped around Merlin. Merlin was gasping and moaning as I swallowed him whole and began to lick and suck as I bobbed my head. I grazed my teeth a couple of times and he yelled

"FUCK ARTHUR, I'M ALMOST THERE..." I smiled and played with his balls and soon he came hard yelling my name

"ARTHURRRRR...FUCK!" I swallowed every single drop of his cum before releasing him and kissing back up his body. He was huffing and puffing like he had just finished a major workout. I pecked his chest, then his chin, his cheek and then his lips. He smiled

"Mmmm, I can taste myself on you." I smiled back

"Yeah you taste fantastic." I kissed him deeply and he wrapped his arms around me. I pulled him close and laid myself on top of him. We kissed and touched everywhere, just exploring when he rolled us over so he was straddling me. He smiled

"Fuck me Arthur." I smiled up at him and asked

"Why?" He leaned down and said

"Because junior is poking my ass as we speak and I know you love my tight little ass." I smiled and rolled over and said

"yes I do". I slipped my fingers into his hole and he gasped

"Arrh, Arthur yes please more." I slipped in a second finger and then a third before he was ready. I grabbed the lube off the night stand and coated myself and his hole before kissing him and slamming myself in him. We both moaned and Merlin pulled me down to kiss him. I waited a moment, letting Merlin adjust before pulling out and thrusting back in.

We quickly got a rhythm going and soon we were both sweating and gasping as we made love. I continued to kiss him and cover him with love. I was getting close so I gripped Merlin's cock and began to pump him. He pulled me back down and kissed me hard before cumming quickly all over our stomachs. A few thrusts later I came in his ass and dropped on top of him.

He smiled and said

"I love you Arthur." I smiled and said

"I love you too, now I have to go, stuff to do for tonight." I hopped up and passed him a towel to clean himself up and he asked

"Yeah about tonight where are we going?" I smiled again and said

"You shall find out later, it's a surprise, but dress nice, wear that suit Morgana brought you last week." Merlin nodded and I kissed him once last time before jumping in the shower.

I had a quick shower and when I came out into the kitchen Merlin had breakfast for me ready alone with a coffee. I pecked him on the cheek before I grabbed it and sat down at the table. Once I finished my breakfast I put the dishes into the sink and grabbed my stuff for work. I had a busy day ahead. I had two meetings in the morning before lunch time, a lunch I was picking up the ring before going back to the office for another meeting.

When I arrived at the office Morgana walked up to me and asked "Is everything ready for tonight?" I nodded my head

"Yep, everything should go perfectly, I just hope he says yes." Morgana grabbed my arm to stop me from walking and made me face her.

"Merlin will say yes. He has no reason to say no. You two have been together forever, he wouldn't have put up with you for this long if he didn't love you. Now just know he is going to say yes because he will, ok." I nodded my head

"Ok, yeah." She smiled and wished me luck before walking off.

My day went very quickly and within no time at all I was driving home to get ready to take Merlin out. Everything was ready; I had been to the restaurant and made sure everything was set up. We were in a private area and we had our own private waiter and a made playing the violin. I was dressed and ready and waiting for Merlin in the living room. I was dressed in a black suit with a dark blue shirt and black tied. My hair was done nicely and I could feel the ring box burning a hole in my pocket. I was nervous but not about the evening going bad, I was afraid Merlin would say no, well I guess that would be the night going bad but I just hoped he did say yes because I know most relationships didn't last threw a rejected proposal.

I heard Merlin walk into the room and as I turned around Merlin stood there in a black suit with a white shirt and a black tie. I smiled and said

"You look very handsome." He blushed and I chuckled, I loved it when he blushed. I pulled him to me and kissed him deeply and he said

"You look very handsome yourself." I kissed him again and said

"Thank you love." I took him hand and we left.

Pulling up to the restaurant Merlin smiled and said

"Arthur this look really expensive." I chuckled and said

"Oh it is but you are worth it and you cannot complain because I never get to spend money on you." Merlin sighed but smiled as we walked in.

We were sat our table and Merlin just couldn't stop smiling. We order drinks and our food and fell into an easy conversation. So far so good. Our food came and went and I wasn't nervous anymore, I was excited. After we ordered our desert I stood up and was handed a guitar. Merlin raised an eyebrow and asked

"Arthur what are you doing?" I smiled and said

"Merlin what I'm doing is going to sing for you, now shut up." He pouted but smiled as I sat down. I began to strum and felt a smile pull on my lips.

I placed the guitar down and by now Merlin was smiling with tears in his eyes. I knelt down beside him and asked "So what do you say, do you wanna marry me?" I pulled out the ring and Merlin's mouth dropped open. He began to cry and said

"Of course you prat, of course I will marry you." I slipped the ring on his finger and he jumped up and kissed me. I wrapped my arms around him and we continued to kiss. Tonight was a complete success and the one thing I knew was that tonight I was so getting laid.
