I would want to give special thanks to Karlijn, who is my Sherlock buddy and always let me ramble about it and to Nele, I'm not sure if she'll ever read this, but she always listens to what I've written down so thanks.

I love you all and have two more short one-shots about this two coming up.

One year later

"John will you just relax."
"No Sherlock, I will not relax. It's Christmas, your mother and Mycroft are coming over, this place is a mess and you have been lying on the couch all day."
Sherlock looked around. It had never been this clean in their flat before. He had put all his experiments away, had picked up his clothes that were still there from last night, he had hung a picture off John and himself over the gunshots in the wall. He had even bought a new television, since he had destroyed their last one for an experiment that involved cats, water and electricity. Don't ask, it was for a case. The floor was visible and that was for the first time since he had moved in. He couldn't see what was wrong, but knowing John like he did by now, he knew that John wouldn't relax until Mummy and Mycroft would have gone home.
"John, Mummy won't even look at how our house looks. She will be happy enough that you are still in here and haven't decided that I was too much trouble. So if she will think it's a mess, she will blame me for throwing everything on the floor, or for giving you too much to deal with, and that's the reason why you aren't able to clean. And let's be honest, she right in both cases. And for Mycroft, well he has seen this place much worse. Don't worry, my dear."
Most of the time it worked when he nicknamed his boyfriend, but apparently this was a special occasion. He only didn't know why. Well, he was the world's only consulting detective, it would be a piece of cake to find it out.

He stood up and walked to John, where he circled his arms around John's waist, like he had done that that day on the train station and so many times again by now. He loved the feeling of John in his arms and John would love to feel how much Sherlock cares about him (John's words, not his.) and let himself relax in his arms.

"Why are you freaking out? You've met Mummy last year and Mycroft is here more then you or I wish. There is nothing special about it." OK, not his best trick to discover the truth, but he knew in John's case it was more of a guarantee for success than using manipulation. That would only make John angry.
John sighed and putted his head against Sherlock's shoulder.
"I know, but last year we weren't in love." Sherlock tensed his muscles around his waist. "Alright, maybe we were, but I didn't realise it but for the last night. And then we made so much noise the neighbours from 3 kilometres complained." He quickly added. "I just really want to impress your mother. As a decent boyfriend. After all, I am the one who's dating her baby boy."
Sherlock laughed "John I think it's safe to say we're in a relationship by now. Dating is for children and desperate grown-ups. We're neither one of those."
"I don't know Sherlock, you can behave like a little child sometimes."
They smiled together, happy to have this moment with each other.

"If this isn't the right moment, there will never be a right moment." Sherlock thought.
"John wait here, right here and don't move a finger." He said before running to their room.
John smiled. He had no idea what Sherlock was planning this time, but as long as it wouldn't make a mess in their just cleaned flat, he could deal with it.

Sherlock bounced of the stairs, not surprised to see that John actually hadn't moved a finger. John would always say it was part army training, part Sherlock, which had made him so patiently.

Sherlock was actually getting nervous. Having a great mind, like he had, wasn't always a gift, since he would always see twenty different scenarios. It was useful in cases, but terrible in moments like these. But he had to do it. After all, John loved him, he had said so on different occasions, so he wouldn't refuse him. It was for John as much as for himself and he would do everything for John. So this as well. For John's happiness. And for his own.

"John please sit down."
"Why? What's going on? What have you done? Sherlock what are you planning?"
"Just sit down, please. It's important to me and you are going to like it as well."
"Fine." John answered unsure if he would have to punish Sherlock. On Christmas and their anniversary. Better first listen to what Sherlock wants to say.
Sherlock was still surprised how much John trusted him. It made him feel warm inside.
"John, I know we've only known each other for two years and been together for just one, but for me that's a long time to be with someone, without getting bored or annoyed.
And after all this time, I still love waking up next to you and I love making love to you, and I love your tea and I love your jumpers and in general, I just love you and I don't think that will ever change. Actually I'm sure that it will ever change. So" he knelt down on one knee and took a velvet box out his trousers and opened it. "John Hamish Watson, will you do me the great honour of marrying me?"
"Yes, yes, yes, yes Sherlock, yes" John said with tears in his eyes "yes"

He wrapped his arms around Sherlock and kissed him deeply, not planning on letting go for some time.

One hour later they were still lying together in bed.
"We'll have to clean the house, you know that right?"
"Why? Hadn't we agreed that the house is clean enough?"
"For my boyfriend's mother it may is, but for my fiancée's mother it most certainly isn't."

And there would be fights like there used to be, there would be insults, there would be slamming doors. There would be lonely nights when John didn't come from Harry. Sherlock would spend a lot of nights on the couch, when he had forgot to tell that there were toxic experiments in the fridge. But to be honest, he looked forward to all of that, because that's how he and John worked and he wouldn't want to live without any of that. And after talking and everything else they would do to solve their fights, there would always be the amazing make-up sex, the one for which Sherlock would probably leave some heads in the fridge on purpose.

And after the wedding everything would be like he wants it to be: he and his John, for now and forever.

Thank you all and I would love to hear what you thought about it, as always!
