I love Klaine AU's. I really do. Especially with all the Klaine Break-Up rumours going around everywhere.

I really don't like those rumours. I really, REALLY don't.

Therefore, I am going to drown myself in Klaine AU fics. But to start with that, I wrote one myself.

She is my sin – Nightwish.

It wasn't allowed, Kurt told himself while he couldn't help but stare at his new neighbour.

Kurt lived in a tiny house with only a few rooms. It was 1956 after all, things weren't expected to turn out great in the economy anytime soon. Kurt was just glad to have a job as journalist for a newspaper. It had caused him a lot of trouble to find a job, and even more to be able to hold on to it.

Which was why he wasn't allowed to look at men the way he did.

He wasn't allowed to be gay.

But then, his new neighbour had arrived and he could simply not keep his eyes off of him.

The man had dark, curly hair and dressed very nice, with bowties, suits and shiny shoes.

Kurt honestly wondered what a man that looked as rich as him did in a neighbourhood like this. But he couldn't ask the guy. He was terrified to give himself away.

So he kept quiet, instead staying focused on his work.

It was seven in the evening and Kurt was just finishing an article he had to have done before work the next day, when the bell rang. Kurt frowned.

He never got visitors and if he did, they were either his father and stepmother, his stepbrother or one of his friends, which weren't all that many people.

He got up and walked towards the door. He unlocked it. He was used to having a lock on the door. The neighbourhood he lived in was full of criminals, most of which were thieves, or homeless people who were looking for a warm place to stay. He just never knew who he could or could not trust. Not there.

But when he opened the door, his jaw dropped. There was a man standing in front of him.

'Hello. I'm Blaine Anderson. Nice to meet you.'

Kurt shook his head and felt his cheeks colouring a violent shade of red.

'H-hi. Nice to- Nice to meet you, too.' He cursed his voice at that moment, as it got higher the more he spoke.

'I was wondering if it was alright if we talked for a bit. Get to know my neighbours, you know?'

'S-Sure. Come in.'

So, the curly-haired man named Blaine Anderson walked in and once they both had tea and were settled on the old couch in Kurt's tiny living room, they talked.

And talked.

And talked.

It appeared they had a lot in common.

Weeks later, Blaine Anderson and Kurt Hummel had become very good friends and Blaine sometimes came over at Kurt's place or Kurt came over at Blaine's, even when there were friends.

One night changed it all though.

They were sitting on Kurt's couch once again, talking about their week. Kurt hadn't really noticed Blaine's eyes constant flicker towards Kurt's lips, but what he did notice was that Blaine seemed to be very quiet and it worried him.

'Blaine? Are you alright? You're awfully quiet, you know. If I'm boring you, please just tell me.'

Blaine just grunted a vague reply, while shaking his head in a 'no'.

Then he licked his lips and put a hand on Kurt's cheek. And before he knew it, Kurt felt a pair of warm lips on his own. A jolt of excitement went through him, but Blaine pulled away before he could properly kiss him back. Kurt opened his eyes, wide in surprise, to find Blaine staring at him with a look of horror, embarrassment and shock on his face.

'I-I'm so, so sorry, Kurt. I-'

'Blaine-

'I should go.'

Blaine's face was red and tears were pouring down his cheeks as he ran out of the door, slamming it shut behind him.

For a couple of minutes, Kurt just… Sat there. Thinking.

He knew his father wouldn't like the fact that he wanted something like a relationship with Blaine. Or any boy actually.

That wasn't because he did not support Kurt or was disgusted with him or thought it was wrong or anything like that.

It was because it was the rest of the world that thought it was wrong for two men to love each other unconditionally. Or to be together at all.

They saw it as unnatural, no matter if it really was or not.

Kurt knew he'd get trouble if anyone found out.

Kurt knew people would hate him. He knew he could lose his friends and more than likely even his own stepbrother Finn would hate him for it.

He knew it could be a risk for his job.

He also knew he didn't really care about any of that.

But what was the most obvious thing…

It was the fact that he was undoubtedly, undeniably and utterly head over heels for Blaine.

And Blaine seemed to love him back.

Without another thought, he jumped up and in less than a minute, he was standing in front of Blaine's door, hand heaved to knock. He bit his lip, tasting just a little of Blaine there and knocked.

It almost took a whole minute, but at last, the door was opened, revealing Blaine, tear streaks still very much visible on his face. His eyes were red and a little puffy and the look of pure fear returned as he realized it was Kurt standing right in front of him.

'Kurt, I am so sorry. Please don't tell anyone.'

He sounded miserable and that alone was enough for Kurt to push him back inside Blaine's own house and close the door behind him.

Once the door was closed and once Kurt had pulled the curtain along the window, effectively shutting out the rest of the world, he turned to Blaine, who somehow managed to look even more scared and impossibly adorable.

Before he was even aware of what exactly he was doing, he had his arms around Blaine's neck and he kissed him.

'Mmpf.' Blaine tried to talk, but got lost in Kurt's kisses. After a few minutes of heated kisses, Blaine started pulling him towards the bedroom. They fell on the bed together, Blaine on top of Kurt and after two exclamations of 'Oof', things got more heated very, very soon.

'Blaine?'

'Yeah?' The guy breathed out.

'I… I know I'm already 23 years old… But I've never… Never really done anything like this.' Kurt said, obviously embarrassed.

'Well, then, Kurt. Want to know a secret?'

'Um, sure?'

'Me neither.'

Just for a second, Kurt stared at Blaine, who now only had a pair of underwear left, surprised at this secret.

'Really?'

'Really.'

They smiled.

Hours later, the two of them were just lying in bed, staring at each other.

Kurt knew this was the very start of an apparently sinful relationship between the two of them.

But both of them were aware of the fact that neither of them minded the other being their so-called 'sin'.

Because they loved. They were in love. And no opinions could change that.
