This is a TVDU AU. It includes spanking, infantilism and age play. If that is not your thing, please scroll on. The story is mainly focused on Kol/Elijah, but will also include their relationships with Rebekah and Klaus.

Elijah sits in his favorite leatherbound armchair, a worn Melville in hand. In the entry way, the door creeks open. Elijah drops his book and zooms in. Kol's eyes widen for only a moment before putting on his usual tough bravado. Elijah tsks at the blood smeared from one end of his mouth to another.

"Couldn't have bothered cleaning yourself?"

Kol rolls his eyes. "It's well after midnight. No one is going to notice."

"They could've." Kol opens his mouth and Elijah holds up a hand. "Speaking of, what were you doing out so late?"

"I was starving."

"Last I checked, Rebekah stocked the fridge with bags from the blood bank."

"I've been out of practice for a good hundred years," Kol counters. Elijah pinches the bridge of his nose. Every time he's criticized or corrected on an issue, he throws in the dagger. "What? I need to readjust to feeding off humans."

"That may be true, but you know you're not supposed to go out alone."

"Reminder, I was 20 when turned. Not exactly a toddler."

"No, but you might as well be a newborn vampire. Did you even erase and release?"

Kol ducks his head. Elijah's jaw tightens. This has been a point of contention ever since they all tried to start over. Kol cannot control his urges, he attacks and yet another human is sent to the morgue. It's exactly why Elijah came up with this rule in the first place.

"Up to my room, nose in the corner."

Kol scoffs. "Right. You're going to put me in timeout?"

"Yes, after I whoop your ass."

Kol's nostrils flare as his head snaps up to his big brother's. Elijah stays firm. He points to the stairs. Kol shakes his head, trying to walk past Elijah.

"The others may fall into your power trip, but I certainly won't."

"Kol, you have until the count of 3. 1…"

Kol heads for the kitchen. "Whatever."

"2." He raises an eyebrow when his brother continues walking. "3." Kol begins to disappear out of sight.

Elijah grabs his brother by the waist and throws him over his shoulder. Kol shrieks, kicking his legs and trying to get out of his grasp. Elijah keeps a firm around him, carrying him up the stairs. Elijah shakes his head at the screaming and kicking, with promises to have him killed.

"Sure you will, baby brother."

Klaus' bedroom door opens and he pokes his head out. Upon seeing the tantruming Kol, he smirks and ducks back inside. Elijah walks into the master bedroom. With a swift movement, his belt is off. He sits down on the bed and moves Kol over his knee. His brother screams louder.

"What the hell is the matter with you?! You can't do this!"

Elijah ignores him. Being the second oldest, as well as several years older than his siblings, he's learned to not give attention to less than desirable behavior. Instead, he'll just punish him for it later. Elijah unbuckles Kol's belt and unzips his jeans. He removes his shoes and socks, piling the jeans on the floor. Kol's hands go over his boxers. Elijah smacks his hand away and pulls them down. Kol's face is burgundy.

"Stop! I swear, Elijah, I will have you dag…"

He's cut off by a firm smack to his bottom. Elijah uses his palm to start with. He takes great care with each cheek, striving for perfection as always. It's been ages since he spanked Kol and he still has the same adorable bottom. A bit of baby fat that remained frozen due to vampirism. Elijah can't help but smile at the memory of his little brother, chubby cheeks and tummy. Elijah chuckles as he watches his bottom go from pale to bright pink. Kol kicks his legs and tries to roll over, but Elijah smacks his thighs every time. His brother's cursing turns to just screams.

Elijah speaks for the first time since they came upstairs. "Can you tell me why you're getting this spanking, Kol?"

"Because you're a dick!" Elijah raises his hand and smacks it hard on his sit spot. "Ow! Okay! Okay! I went out without you!"

Elijah delivers three more blows. "What else?"

"I…I didn't compel and release."

"And?" Five more blows turn his bottom from pink to light red. Kol wiggles, confusion written on his face. "I need an answer, little brother."

Kol clearly needs time to think it out. Elijah smacks his right cheek then his left before letting up. He reaches down and grabs the belt. Kol sniffles, biting his lip.

"It's because I didn't come when you asked."

"That's right," Elijah says. "If you had, I would've stuck with 10 with the belt. What happens when you make big brother wait?"

Kol whines, pouting. Elijah hides a smile. He really looks like his tiny baby brother in this moment. "I'm not a child anymore!" Wrong answer. Elijah smacks his hand down. Kol yelps. "Okay, okay. If I make you wait, it gets worse."

"That's right. I want you to count these, Kol."

"But it's going to hurt."

"That's the point."

Elijah loops the belt. This he isn't out of practice with. While it may have been awhile for Kol, he's had to take the belt to Klaus and Rebekah a couple of times. The difference is, they don't look so young and pitiful over his lap. He raises it up high, then thwaps it against Kol's bottom. His brother yelps out.

"1!" THWAP! THWAP! "Ow! 2! 3!" THWAP! "4. Please, Elijah!" Elijah smacks harder. "Nooo! 5! I…I'm sorry! I won't do it again!"

"This'll ensure you don't. Along with the rest of your punishment."

"The rest…" Kol trails off when the thick leather collides with his bottom. He breaks down into tears. "6!"

"Do we sneak out of the house?" THWAP!

"7! No!" Kol wails. THWAP! THWAP! "8! 9!"

"Do we hunt by ourselves?"

"No! I'm sorry!" Elijah hits his thighs. "10!" Three more smacks turn Kol's bottom a deep shade of crimson. He's wailing like a toddler, tears and snot mixing in with the blood on his face. "11! 12! 13!" Elijah winds back his hand, making the next one really count. "14! Owwie! 'Lijah, please. I'll be good! I'll be good!"

Kol's body goes limp as Elijah smiles. It's been forever since any of his siblings have called him 'Lijah, most of that stopped by the time they were in their teens. A part of him wants to stop the spanking and give cuddles, but he also knows he needs to follow through. The leather and plump, baby bottom collide once more. Kol whimpers, his voice defeated.

"15," he whispers.

Elijah rubs his back. Kol's eyes stay on the carpet. "You go put your nose in that corner and then we can have a talk."

"Another spanking?"

"No. I think you've had your fill for the night. As long as you stand in the corner, your ass is saved."

He helps Kol to his feet, watching as his baby brother limps to the corner. He doesn't have to be told to put his hands on his head. Elijah wonders if it's a good thing he's so used to these punishments. When Kol was little, the older brother tried to use spankings sparsely, but it was hard when he always got himself (and often Klaus and Rebekah) into trouble. Elijah sighs, pushing himself off the bed and heading for the stairs. Rebekah leans in the doorway of her own room, holding her robe closed.

"Why was Kol screaming?"

"That's none of your business. Go back to bed."

Rebekah tilts her head, her eyes glittering with excitement. "Did you spank him?"

"I'm going to get the hairbrush if you don't get back in bed right now."

Rebekah pouts but disappears back into her room. Elijah shakes his head, pinching the bridge of his nose. Immortal teenagers. He heads downstairs and wets a washcloth for his brother's face. After digging through the cabinets, he finds some lotion. He's back up in a flash. Kol's nose is still in the corner, hands on head, whimpering. Elijah sits on the bed.

"Come lay down on your tummy," he instructs.

Kol limps back over and does as instructed. Elijah squirts a bit of lotion onto his palm and gently rubs it onto his baby brother's bottom. Kol expels a sigh of relief. Elijah smiles, rubbing it deeper.

"Feels good, huh?" Kol nods. "I'm glad."

"It'd feel good if you didn't whip me," his baby brother mumbles.

Elijah chuckles. "Well, if you weren't naughty, I wouldn't have to."

Once the lotion is rubbed in, Elijah gathers his brother into his arms and pulls him onto his lap. Kol cuddles against him, just like he used to as a boy. Elijah takes the cloth and wipes his face. Kol tries pulling away, but he's fast.

"You used to do the same when I tried to clean you after supper," Elijah muses.

"'Cause 'm not a baby."

Elijah watches as his brother's thumb enters his mouth and he begins sucking on it. He kisses the top of his head, gently rocking him. "Of course you're not. You're 'Lijah's big boy, right?" Kol nods. "Okay then." Elijah continues to rock him, not wanting to let him out of his sight for the time being. Kol mumbles something that even vampiric hearing cannot pick up. "What's that, my little prince?"

Kol's eyelids flutter a few times. "Other punishment," he whispers.

"It's not really a punishment. It's something that'll help you a great deal. But we don't have to talk about that right now. Get some sleep, sweetheart."

Kol nods. "'Kay. Love you, 'Lijah." His eyes shut as he snuggles closer.

Tears spark in Elijah's eyes. "I love you too, my little prince."

Elijah keeps Kol in his arms all night. He does pull his boxers back on eventually, only after his bottom has time to air out. Elijah sends a text to Klaus, asking him to get the rest of what's needed for the day. His brother walks in a few moments later, holding the bag. He smiles at the two, shaking his head.

"I always knew you carried a fondness for him."

Elijah tilts his head. "Never said I didn't."

"You've often acted as if he's a bother," Klaus points out, putting the bag on the nightstand.

"I'm the older brother. It's my job to keep you three in line. Even when Finn was around, Lord knows he never took the role seriously." Klaus purses his lips and nods. "It doesn't mean I don't love you."

"Aw, Lij, you do have a heart."

Elijah rolls his eyes, waving to dismiss him. Klaus slips out the door, accidentally slamming the door behind him. Elijah flinches, trying to rock Kol to keep him asleep but his eyes flicker open anyway. He whines a little, still sucking on his thumb. Elijah smiles and strokes his cheek.

"Good morning, Sunshine." Kol twists his body. His thumb drops from his mouth and he attempts to sit up, hissing whenever his bottom collides with Elijah's sleep pants. Elijah adjusts him so he's still in his arms. "No need to move."

"I don't need to be cradled by my big brother," he mumbles.

Elijah strokes his hair, ignoring the statement. "Did you have a good sleep?"

Kol gnaws on his lip. "Best in awhile."

He smiles. "When you were a baby and Esther needed a break, you'd sleep on my chest." Kol looks up at him with wide eyes. "You always gave her such a hard time. With me, you'd fall right asleep."

"You took care of me when I was a baby?"

"Of course I did. There were a lot of kids running around, Mikael certainly wasn't of help." They both cringe at the name of their father. "Someone had to tend to a cheeky monkey."

Kol's cheeks tint. "Why did you cuddle me after my spanking?"

"Because as much as you like to pretend otherwise, you are still my baby brother." Kol opens his mouth to speak but Elijah holds up a hand. "I know I haven't been the best brother myself, but I want that to change now."

Kol sniffles. "Really?"

"Really. But that also means things around here have to change."

Elijah sits up straighter and adjusts Kol so their eyes connect. His little brother appears riddled with anxiety. Elijah bounces him a little.

"You're right, you need to reacclimate yourself to not just this family, but the world. In many ways, you are like a baby." Kol frowns. "I know that's hard to understand, but you are. And that means you need to be monitored and cared for."

"Monitored?"

"You are no longer able to go out alone, and we're going to do more to make sure that's enforced. You'll sleep in here with me." Kol's mouth drops open. "If I have to leave, you'll either come with me or Klaus and Rebekah can watch you."

"Rebekah's younger than me!"

"Yes, but she's more mature."

Kol wrinkles his nose. "What about hunting? Are you going to hold my hand to make sure I compel and release?"

"In time I will. But we'll have to build up to that. For now…"

Elijah trails off and reaches into the tote. He pulls out a baby bottle filled with blood. Kol's eyes about bug out of his head.

"No! Can't I just drink out of a bag?! Or a glass?!"

"As I said, you're still learning. So for now, this is what we're going to do."

"But I'm not a baby!"

"Kol, we've talked about this. Do you want to get better or not?"

Kol expels a dramatic sigh, trying to bury his head in his brother's shoulder. Elijah places two fingers under his chin to keep it up.

"This isn't a punishment, baby boy. It's to help you."

Kol frowns. "Do I have to?"

"I'm afraid so. But once you reacclimate, it'll all be over."

Kol slowly nods, eyeing the bottle. "No one has to know, right?"

"It won't leave this house, I promise. And your brother and sister won't tease you about it either."

"Yes, they will."

"Not if they don't want a trip over 'Lijah's knee."

That gets a giggle out of Kol. Elijah grins and moves him back into the cradle position. He reaches into the bag and pulls out a bib, tying it around Kol's neck. As soon as the nipple is in, Kol begins sucking, closing his eyes and humming a bit. Elijah presses a kiss to the top of his head.

"Good job, my little prince"
