A/N: So I saw a post on Tumblr about Karoline AUs and one of them were a Student/Teacher so I thought, why not. This is part one of two. I'll post it when I write it, which won't be soon since I still have to write NYAH. Anyways, Enjoy!

"I think you should take a chance and tell him." Katherine said to her best friend Caroline.

"Kat! No way, Care you can't do that." Bonnie said.

"Why not?" Caroline said angrily while closing her locker and turning around to her best friends.

"Well for starters he's our history teacher. And you could have a little crush that'll mean nothing." Bonnie said.

"Well she'll never know if she doesn't ask him out, Bon-Bon." Katherine said smirking.

"Or that could get him fired and you expelled. And Care there aren't any other schools here in Mystic Falls so you would be screwed." Elena said.

"I KNOW!" Caroline screamed. Everyone in the hall became quiet and looked towards their direction. Katherine broke the silence. "What?! Nothing to see here go to your classes." Caroline took a deep breath and checked her phone for the time.

"I got to go to class. Bye guys." Caroline said slowly walking away.

"But we all have history right now." Bonnie said.

"Leave her. She wants to be alone. You two made her depressed." Kat said.

"Bennet?" Mr. Mikaelson said taking attendance.

"Present."

"Carson?"

"Here."

"Forbes?"

The room was silent.

"Forbes?" Mr. Mikaelson looked up to Caroline's seat and saw no one there. The door opened and Caroline walked to her seat.

"Ah, Ms. Forbes there you are. Decided to be late to my class today?"

"I'm sorry, Mr-" Caroline tried to apologize but was interrupted.

"No need to apologize. But you do have to stay after class for detention." All Caroline could do was nod her head. She was thinking about her being alone with Mr. Mikaelson after school, with no one around. Why does he have to be so young? And so hot? And our history teacher? Caroline thought. Mr. Mikaelson was only 24 years old. Yeah, He was 7 years older than Caroline, but she didn't mind. The only thing she cared was that he was her teacher. Caroline was snapped out of her thoughts by Mr. Mikaelson continuing the attendance.

"Gilbert?"

"Here." "Present." The Gilbert twins looked at each other with an annoying look.

"Halfway through the year and you both still do it." Mr. Mikaelson said annoyingly. The class laughed and he continued the attendance. Katherine turned back to Caroline.

"Are you gonna be ok being alone with him?" Kat whispered.

"Um- yeah. I mean I have too."

"You could tell him how you feel then. With no one around, no one could stop you."

"Hathaway?"

"Present."

"No. Elena and Bonnie are right. He could be fired and I could be expelled."

"Lockwood?"

"Here."

"Who cares?"

"I do. I don't wanna be expelled, Kat."

"Salvatore?"

"Then tell him how you feel now. Ask him if he likes you. If he does, then the'll wait until after graduation."

"Present."

"Alright class…"

Katherine turned around and Caroline took out her notebook.

"Take out your textbooks and go to page 284. Can anyone give me a recap about World War I?"

"Mr. Mikaelson aren't you going to collect the homework?" Ally, the student in the front of the class said. Half the class groaned and the other half gave her a dirty look.

"Yes, Ally thank you for reminding me. I was going to collect it after the lesson, but since I can tell most of you haven't done it, I'll collect it now. Pass it forward."

Stefan turned around to get his homework out when he saw Caroline not moving.

"Care" Stefan whispered.

"Hm?" Caroline said snapping out of her thoughts.

"Did you not do your homework?"

"He's collecting it now? I wasn't paying attention."

"You never are. Stop daydreaming about Mr. Mikaelson."

"I know, I know." Caroline said while turning around to get her homework. This is gonna be a longgg day. Caroline thought.

"And what was the cause of World War I?" Mr. Mikaelson asked. Everyone became very quiet all of a sudden.

"Hm. No one?" Klaus looked around the classroom to see all of his students faces. His eyes stopped at Caroline. Caroline felt eyes on her so she looked up and noticed he was looking at her. She looked down immediately, but Klaus couldn't help but notice that Caroline's cheeks became very pink and he slightly smiled. Klaus continued looking at his student and he found the person he wanted to call on.

"Ah, Mr. Lock-"

RINGGGG

The bell rang and the student immediately started packing.

"Saved by the bell. All right, you are all free to go." Everyone stood up and left. All except one.

All except for Caroline Forbes.

Klaus would be lying if he said he didn't think that Caroline was attractive because she was. Even though she was his student, he sometimes fantasized about her. And the thoughts have been more continuous lately because of Caroline's glances.

"Mr. Mikaelson, I don't wanna be rude but if your gonna keep me here for detention, I would actually prefer to do something than to stare at the wall."

"Very well, Ms. Forbes. You can fix those books in the back. Please arrange them alphabetically." She stood up and started walking toward the book shelves. While she was fixing the books, Klaus was going to be grading papers, but now all he could do was stare at Caroline. He tried to forget she was in the room and it worked for the remainder of the time.

Caroline was almost done organizing the books, surprisingly she did it in an hour and a half when she thought she would be done in 30 minutes. Everyone was out of the school and she and Mr. Mikaelson were the only ones left in the school. She couldn't help but think if she should take Katherine's advice and tell Mr. Mikaelson how she feels about him. Caroline finished and walked towards Mr. Mikaelson's desk.

"Yes, Caroline?" Klaus said looking up at her. Caroline felt shivers down her spine at the sound of Mr. Mikaelson calling her by her first name.

"I'm- um- finished with the books." Caroline said awkwardly.

"Alright. Since I don't have anything else for you to do, you can leave now."

"Thank you Mr. Mikaelson." Caroline grabbed her book bag and slowly walked towards the door. She took a halt, turned back around, and walked in front of his desk again. She took a deep breath and started talking.

"Mr. Mikaelson. I have something to tell you that I really shouldn't be, but I'm going to anyways. And I could completely humiliate myself, but I've already started so their's no backing down now and-"

"Caroline! To the point please."

"Oh, right. Ok I'll just say it." She took a deep breath and talked again."

"I like you…" Caroline confessed. Klaus' eyes opened wide and his mouth opened.

"And I know I'm not supposed to because your my teacher and I'm your student, but I wanted to tell you."

Klaus stood up, went around his desk and looked down at Caroline.

"Caroline, to be completely honest, I like you too. But because of our circumstance, we cannot be together. I'm sorry."

Caroline looked at the floor and back at Klaus. "I know. I'll just go." She was walking past him when he grabbed her arm.

"But… you are a senior. Tell me love, have you failed any classes?"

"N-no. I have a-all st-straight As."

"Great. Then I'm sure you'll graduate this June correct?"

"I-I hope so."

"Great. If you are willing to, we can wait until the school year is over and you graduate, I could take you on a proper date. Or of course we could risk it and fool around for now." Klaus smirked.

Caroline got out of Klaus' grip, walked a little closer to him and whispered "Why not have both?" and kissed him so hard he had to hold on to his desk for support. She put her hands on his cheeks and he put his hands on her waist.

"Wait-" Klaus broke apart from Caroline briefly. "The door." Caroline ran to the door, locked it and went back to Klaus. They smiled and kissed again. Klaus backed away from Caroline and moved some things from his desk. He kissed her again, turned her around, picked her up and sat her down. He opened her legs a bit and put his body between them. They kissed hard and passionately; his mouth went from her lips to edge of her mouth to her jaw and to her neck. Caroline slightly moaned when she felt him sucking on her skin. "Don't leave a mark." She managed to get out. "A bit to late for that, love." he said smirking "What the hell am I supposed to do now?" "Apply makeup, or wear a shirt with a collar." Caroline kissed Klaus again and she started kissing his neck. She broke away from him and started unbuttoning his shirt. She took it off and threw it somewhere in the room. She was unbuckling his pants when he cupped her cheeks and kissed her. One of his hands were going to her back, Klaus grabbed her zipper and slowly unzipped her dress. She stood up from the desk, moved her dress from her shoulder only an inch, and watched Klaus' face while her dress pooled near her shoes.

"Caroline, you are exquisite." Klaus said while sitting her on the desk again and kissed her lips once. "Love, lay down for me." She looked at him skeptically but obliged. He could tell she was nervous, so he kissed her. "You have nothing to be worried about." "I have a lot of things to be worried about regarding this but ok." she said laughing. Klaus ignored her comment and kissed her neck. She moaned a bit too loud and that made him smirk. Klaus then kissed her breast, right above her bra, and then slowly went to her stomach. He looked up at her and she had her back arched, he smiled once again and kissed her abdomen. Klaus looked back at Caroline and he saw she was looking at him, he smiled at her and she smiled back. He grabbed her panty, he slowly moved it and started pulling-

RING RING RING

Klaus and Caroline looked at Caroline's book bag. Her phone was ringing. Klaus stood up and went to get it. "Smallest pocket in the front." She said. He handed it to her and she read the name. Elena It read. Caroline rolled her eyes and put the phone next to her.

"Aren't you going to answer it love?"

"No. Can you continue please?"

"Of course."

The ringing stopped and Klaus smiled at Caroline. He kissed her abdomen once again. When he grabbed her underwear again he started pulling again-

RING RING RING

"Bloody Hell!" Klaus said. Caroline rolled her eyes, sat up and picked up her phone. Katherine. She huffed and picked up the phone.

"What Kat!"

"I want to know where the hell you are."

"Oh I'm- um still in detention." Klaus kissed Caroline's neck and she bit her lip to stop herself from moaning.

"Still? Are you two like- you know?"

Caroline moaned loudly and covered her mouth. Klaus looked at her with terrified eyes.

"OMG YOU TOTALLY ARE!"

"Kat!"

"I'll leave you to it then you lucky bastard."

"Kinda lost the moment but thanks." She hung up and looked at Klaus.

"I'm sorry." She said getting off the desk, picking up her dress and putting it on. Klaus grabbed his shirt and started buttoning it up.

"It wasn't your fault."

"I know but Katherine completely cocked blocked us and she's not even here." She turned around and said "Could you zip me up?" He walked towards her and zipped her dress. He turned her around and kissed her. She smiled at him and he turned around to grab her book bag. He handed it to her and she put it on her shoulder. She grabbed his hand and gave him a light peck on the mouth.

"I'll see you tomorrow Mr. Mikaelson." She said smirking. She turned around, unlock the door and left.

"I'll see you tomorrow Caroline." He whispered.
