This is a bit AU because Kol is still alive

Kol was in the middle of being strangled by a powerful witch, who seemed intent on causing him as much pain as one can cause an original vampire. The seventeen year old vampire felt as if his head was on fire from the inside.

Right as he was convinced that he was going to, or wanted to, die, the pain stopped. Kol looked up and saw a menacing looking older brother glaring at him, but still managing to look concerned at the same time.

"Are you alright?" Klaus asked, pulling Kol into his arms and checking him over.

"I'm fine, Nik. Where's that witch?" Kol said, attempting to get out of his brother's arms. Klaus just held onto him tighter and glared at Kol.

"What did I tell you, Kol Mikaelson?" Klaus asked sternly. Kol winced, remembering their earlier conversation.

Flashback
Klaus was talking on the phone to one of his hybrids. They were discussing a new and powerful witch that had come to town, with the intent of finding a way to kill the originals. Klaus looked over at the doorway and noticed his youngest brother watching him talk.

"I'll call you back." Klaus said, flipping his phone shut and effectively ending the conversation. He gestured for Kol to come over to him.

"Kol, what did you hear?" Klaus asked the teen. Kol shrugged, grinning at Klaus.

"New witch. Very powerful. Wants us dead. Blah blah blah." Kol said, waving it away.

Klaus quirked a brow at him. "Then you know that you are not to go anywhere near this witch." Klaus ordered. Kol rolled his eyes.

"Whatever." He said, standing back up.

"I mean it, Kol. No going near her. If you do, you will not like the consequences." Klaus said, putting a finger under Kol's chin, making the boy look at him.

"Alrrriiigghhhttt." Kol whined. "I won't go near her." Kol agreed. Klaus nodded, pleased, and left the room.

Kol wouldn't go near her. He may be close to her and go looking for him, but he'd be sure to be not near her.

Kol smirked and went to find this witch.

Klaus pulled Kol all the way back to their house and took the kid to the living room where Elijah was waiting for them. Klaus pointed at a couch. "Sit." He said firmly. Kol rolled his eyes at the older man's tone, but sat anyway.

Elijah went over to Kol the second the permanent teenager sat down. "Kol, are you alright?" Elijah asked, taking Kol's face in his hands and looking him over.

Kol rolled his eyes and pulled away from Elijah's grasp. "I'm fine, Lijah. Nik already did the whole mother hen routine." Kol said with a small smirk. Elijah tapped Kol's knee, which was his way of saying that Kol was on thin ice. Kol scooted away from his eldest brother out of reflex.

"So, what do we do about our youngest brother?" Elijah asked Klaus.

"I'm not sure yet. Maybe putting him over one of our knees will do him some good." Klaus said, thinking. Kol looked between his brothers in a mixture of irritation and shock.

"Stop talking about me like some child!" Kol exclaimed, looking furious.

Klaus pointed a finger at him threateningly. "You are a child. A disobedient and naughty child who ignored what I told him." Klaus growled at his little brother. Kol crossed his arms like a chastised child and leaned back in his seat.

"Since it was you who he disobeyed, brother, it should be you who punishes him." Elijah decided, standing up from his crouched position in front of Kol.

"Alright. That sounds reasonable. Kol, we will have this discussion in my room. Now." He added when the teenager made no move to go upstairs. The boy rolled his eyes and went upstairs, resisting the urge to actually stomp. They were being ridiculous.

Klaus looked at his elder brother and sighed. "What do I do?" He asked, sitting in Kol's vacated seat.

"You're going to do just what you said. You're going to put him over your knee and spank him for nearly getting himself killed by disobeying you. Just like we have every time he did something like this." Elijah responded.

"Yes, but I haven't done that to him in nearly a hundred years." Klaus said, looking at Elijah pleadingly. Elijah chuckled at the younger man.

"Niklaus, you have punished our baby brother many times. I'm sure the last hundred years hasn't made that much of a difference in your skill in that subject. Now go deal with him, before he gets too petulant for his own good." Elijah said, smiling at Klaus. Elijah ruffled Klaus's hair fondly. The younger on stood up and smiled back at his brother.

"Alright. I guess I'll go deal with Kol's latest indiscretion." Klaus said, heading upstairs to his room to punish his brother.

Klaus went into his bedroom and looked at Kol who was sitting on his bed with a scowl set in place. Klaus crossed his arms and stared at his brother for a long moment. "Well, child, I guess we need to discuss that events of tonight. In detail." Klaus informed his brother, sitting next to him on the bed. Kol glared at him for being called a 'child'.

"I'm sorry. Alright. We done here?" Kol asked with more than a bit of attitude. Klaus narrowed his eyes at the tone.

"Watch yourself, young man. You're in enough trouble as it is." Klaus warned. "Now, why don't you tell me what made you think it was wise to disobey me, child?" Klaus asked, keeping his voice firm.

Kol decided to switch tactics and try to play at being the adorable younger brother. This always worked better on Klaus than on Elijah. "I thought I could help. Nikki, I'm really sorry." Kol said, giving Klaus the puppy eyes that always seemed to wiggle him out of trouble.

Klaus sighed and pulled Kol over his lap swiftly. "That's not going to work." He said, pulling down Kol's pants and landing a hard swat on his brother's backside.

"Now, Kol Mikaelson, what has happened every time you disobeyed me in the past." Klaus began his lecture, still spanking Kol.

"Argh- You've s-spanked me." Kol gasped out.

"Exactly. So, tell me baby brother, why you thought this time would be any different." Klaus demanded, punctuating each word with a swat.

Kol felt tears prickling his eyes and cursed himself for crying so easily. "I- Ow- didn't think about it." Kol cried out.

"Well, maybe next time you'll remember what happens when you go against what I tell you." Klaus said, being silent after that and just spanking the teenager.

After a few more minutes if silence, Klaus heard Kol start to sob quietly into the bed sheet. Klaus aimed his last ten spanks to the part where bottom met thigh, then stopped the spanking.

Kol was brokenly crying by this point and Klaus pulled him up to sit on his lap.

"Oh sweet child of mine." Klaus said softly, hugging Kol to his chest tightly. "I don't want to have to do that again." Klaus said, tucking Kol's head under his chin.

"No promises." Kol said, managing a watery smile. "I'm sorry, Nikki." He mumbled, sleepily.

Klaus pressed a kiss to Kol's temple. "It's alright, child. I love you so much." Klaus murmured.

"Love you too." Kol said, starting to fall asleep on Klaus's shoulder.

Elijah came into the room a few minutes later and smiled at them. He went over to the two boys and kissed both his younger brother's foreheads. Elijah and Niklaus watched Kol as he slept, just thankful he was alright.
