AN: AU/AH. Carolijah. Caroline has a super horny neighbour who keeps her up at night because the walls are thin and his women are loud. The headboard war begins when Caroline's boyfriend offers to help her get revenge.

Thump.

Thump.

Thump.

Thump.

Thump.

Thump.

Caroline bit her pillow to suppress a scream as her neighbour's bed hit the wall.

Oh God. Yes. More. Harder. Oh God. Faster. Fuck yeah! Oh, Klaus.

With a huff, she threw off the covers and looked at her phone. 1am. ONE AM! That was it.

Pulling on her robe, she stormed out of her apartment and pounded her fist on the door until it opened. A very naked man stood with a smirk but she didn't flinch, blush or look away from his eyes. "Shut the fuck up. The walls are thin and your girl of the night has the most irritating voice of all the tramps you've brought home."

A flash of dirty blonde in a black shirt went passed in the background but she was just glaring at the stone faced man. "Klaus, isn't it? I mean, that's what I heard through the walls," she carried on boldly, "You might want to move your bed to the centre of your sex den or move to a different room otherwise I'll keep coming over to ruin your fun. Have a shitty night and let me sleep for once you selfish man whore."

With that, she turned and proudly walked back to her apartment, slamming the door behind her whilst knowing he was still watching.

"He is so infuriating! I mean, after that he must have pulled the bed away but I still heard the whining and moaning until, like, 4am! I couldn't sleep at all!" She had been going on for about an hour to her boyfriend and only stopped when he walked from behind his desk and wrapped his arms around her.

They were in his office, a glass wall separating them and his workers. It was tinted so no one could see in but he could see out. The windows were the same, letting in the natural light and beautiful sights of New Orléans but not allowing anyone to see in to the office filled with confidential files.

"If he bothers you that much, move in with me," he offered with a small smile. Her eyes snapped up to his and she faltered. "I wanted to ask you anyway but now I believe we can pay him back. Celebrating your moving in might just give him a taste of his own medicine, my love."

"Move in with you?"

"Yes. Please."

"Okay. As long as we fuck all night and keep up my annoying neighbour."

"Gladly. And should he knock on your door to complain, I'll punch him in the face."

She burst in to laughter and Elijah kissed her cheek. "I shall come over this evening and ravish you until the late hours of the morning. We can sleep until it is after noon and we'll have a day in. I would help you pack but I know you're already planning and that I would just be in the way."

"You know me so well."

"As well as you know me. Now, I am officially on lunch break. Would you care to join me?"

"Of course."

Caroline set the plates down and caught sight of the key to Elijah's house on the table. Picking it up, she ran her thumb over the metal and smiled. They had traded keys after three months of being together and now, at eight months as a couple, she was moving in to his house. The lock clicked and she smiled wider as his footsteps moved towards her.

Elijah looked at the boxes around him and chuckled. "Starting already, I see." His hands slid up from her thighs to her waist as his lips pressed up her neck to her cheek. "My contract ends next week and the manager gave me my money back for the next month. I can move in once I'm packed."

"Which I imagine will only take you a few hours now," he laughed as she turned in his arms.

"I was excited and I had nothing else to do. I got a little ahead of myself." His dark eyes bore down on hers as he leaned in to kiss her.

After they'd eaten, Elijah took the plates to wash them and she followed, watching him from her seat on top of the island counter. He took off his jacket and draped it on the back of a chair before rolling up his sleeves. As Caroline sipped on her wine with a smile, she thought about how lucky she was to have such a perfect man to love and love her in return.

Since she was so deep in thought, she hadn't realised he was in front of her until her wine glass had been taken away and his lips were on her neck. His gentleness wouldn't last. She knew that by now. Their first time together had been slow but half an hour later he had turned in to an animal and she loved it.

Tugging her knees, her legs wrapped around his waist and she held on to him as he lifted her to carry her to the bedroom. They made it to the hallway before they both got impatient. After unzipping his trousers and ripping the lacy excuse for underwear she had on, he thrust in to her hard and she let out a strangled scream. Her legs were folded over his arms as he held on to her hips, ramming against her enough to shake the pictures on the wall.

Her nails raked down his back over his shirt and she moaned with her head back against the wall. His lips attacked her neck and the curves of her breasts above her dress. A choked sound escaped her as she tensed, legs shaking and eyes closed. He pulled out of her and dropped her legs. She could barely stand but he guided her to the bedroom with a trail of clothes marking their path. Her bra hung from a light, her torn underwear was kicked down the hall and her dress was thrown to the side. His shirt was left on the floor and his tie joined her bra whilst his trousers and boxers were kicked away with his shoes all in different directions.

Lifting her by the waist with ease, he tossed her on the bed making it shake and knock against the wall. A smile grew on her lips as he smirked. As he lowered himself on to the bed, she turned and rested on all fours looking over her shoulder for him. His hands explored her body from her ankles to her shoulders. One hand moves to her front, squeezing her breasts before wrapping around her neck lightly as he used the other to guide himself in to her. "Oh!" She let out, rocking her hips against him.

His pace was fast and he was deep inside her, shifting to reach different parts of her every few thrusts. His hand around her throat slid down to play with her breasts again and she put her hands against the wall. The headboard was hitting the wall so hard it was denting the wallpaper.

Four hours, six positions and ten orgasms between them later, there was a furious knocking on the door. It was only midnight and Caroline smirked at Elijah. "OPEN THE DOOR!" The voice demanded. It was Klaus. "Hold on," Elijah whispered with furrowed brows.

She watched from the bed where she lay completely spent as he pulled on his trousers and walked out of the room. The door opened and there was silence for a moment. "Elijah?" Klaus asked. "Niklaus?" Elijah returned in confusion. Rushing out of the room with Elijah's shirt on, she stopped behind her boyfriend, arms wrapping around his waist from behind. "So this is your brother? Huh, small world," she commented lightly with a smug expression returned by Klaus' glare. "Think you could keep the noise down, love? Some people are trying to sleep."

She scoffed with a shake of her head. "Welcome to the last two months of my life. To answer your question: No, we won't keep it down." Turning to Elijah, she tugged his hand to lead him away. "Come on, 'Lijah. You promised me sex until the late hours of the morning and I fully intend on having you keep your word." Elijah nodded dazed and slammed the door in Klaus' face.

To say the younger brother got a taste of his own medicine would be an understatement. Two months worth of sex was delivered back to him in a night and to make it more disgusting, he could hear his brother as well as the blonde. That certainly wasn't how he wanted to meet his brother's girlfriend.
