Chapter 4: The Reason

"Kuro-uhn" Shinichi's voice cut off in a gasp and his hands came up to tangle in Kaito's hair. The feeling that radiated through his body was intense and he didn't have any logical explanation for it.

Kaito's arm wrapped around his back and pulled him closer as he took another slow swallow. Shinichi's head went back and Kaito had to struggle to keep his eyes open. He knew that if he closed his eyes, he would definitely lose control.

Shinichi was impossibly hard and rubbed against his leg like a dog in heat. A breathy moan escaped his mouth when Kaito reached between them and began to work him in his hand.

The magician took his last mouthful and licked over his puncture wounds. His tongue trailed back up the detective's neck and he met Shinichi in another kiss. He savoured the taste of the detective's tongue on his and the lingering taste of the blood that aroused him to no end.

He swallowed Shinichi's cries as he came and he shivered. Shinichi fell apart in his arms, his towel since separated from his waist and laid on the floor.

After a few moments, Shinichi's hands left his hair and came up to his chest. The detective pushed at the magician and Kaito didn't try to hold onto him. Shinichi reached down to pick up his towel and walked away from Kaito quietly as he wrapped it back around his waist. Kaito brought his hand to his lips and licked his fingers and watched as the detective went into his room and shut the door, not once looking back at him.

Kaito tapped his fingers on his desk as he looked out of the window, disinterested in the world around him.

His classmates were on edge waiting for his next prank and didn't relax in case he felt the need to pull it when they let their guard down. Even his teachers couldn't concentrate on teaching because they were awaiting something big from their prankster pupil.

Alas, the school day passed and the final bell rang with barely a word from Kuroba Kaito.

"Bakaito?" Aoko was met with a devastating glare from the magician and she took a step back, "what's your problem today?"

"What are you talking about Ahouko?" Kaito sighed as he gathered his bag and stood.

"You've been frightfully quiet today," Aoko put her hands on her hips. "Are you sick?"

Kaito looked down at her before he gave her a blinding smile, "I guess I am feeling a bit down. I'm going to head home first."

He passed her and she frowned, "Kaito you've been acting strangely for these past few days."

Kaito smiled over his shoulder before he disappeared from her sight.

Jii-chan was waiting for him like normal. He sidled into the backseat and Jii drove off. His mask slid off of his face and his irritation shone through. "How is he?"

"He has not left the room today," Jii-chan responded as he turned a corner, "the antidote has worn off and he returned to his child body."

"Thank you for keeping watch Jii-chan." Kaito's lips upturned slightly.

Jii nodded as they pulled up to the house. "Young master, what are you planning?"

"Today, I'll be returning Conan-kun home."

Jii looked at him in surprise through the mirror, "why, young master?"

"I made a promise," Kaito sighed as he opened the door.

He hesitated as he approached the room Conan stayed in. He didn't know how the boy would react but he knocked anyway. He opened the door without an answer and Conan was sitting on the bed, the Sherlock Holmes book on his lap. He leaned on the door frame, "did you finish?"

The boy nodded, "do you have the next one?"

"Do you want it?" Kaito walked to him slowly.

"If you'll give it to me," Conan met his eyes as Kaito knelt in front of him.

"Stay here," Kaito held his hands, "with me."

Conan pulled a hand away and touched the puncture wounds on his neck, "why did you bite me?"

"You were so tempting," Kaito admitted, "I don't know what came over me. I just had to have you."

"And now you want me to remain under your thumb?" Conan shook his head, "I can't stay here."

"Yes, I know," Kaito sighed, "but I won't stop trying."

Conan was surprised when Kaito's grip on his wrist tightened and a hand was pressed to his forehead.

Kaito's glowing violet irises were the last thing he saw before he lost consciousness.

"-do-kun. Kudo-kun!"

Conan gasped and shot up. The motion made him dizzy and a hand pushed him to lay back down.

"Relax Kudo-kun," Conan finally focused on the figure next to him and blinked a few times.

"Haibara?"

"Are you feeling okay?"

"Wha- how did I get here? I was-" he pressed a hand to his face as his head throbbed.

"You've been missing for weeks Kudo-kun."

"How did I get here?" He asked.

"You were brought here by-" she paused and frowned at him, "you don't remember?"

"No..." he closed his eyes and his head throbbed again, "I remember being kidnapped but, the rest is a blur. I must have hit my head. How did I get out?"

Haibara sighed and shook her head, "you know Kudo-kun, I'm not sure. No one knows anything, and if you can't remember, I guess the trail ends there." She placed two pills by the water on the table beside him.

"What are those?" He asked as he cracked an eye open and had a weird sense of deja vu.

"Painkillers, it will help with your headache." She replied, "rest some more, I will check on you later." He watched her as she left the room and popped the pills into his mouth.

"Is he okay?" Agasa questioned as Haibara entered the kitchen.

"He just woke up but I gave him a pain reliever and a sleeping pill. I can't have him wandering around yet."

"I still shouldn't call Ran-chan yet?"

"No," she replied as she picked up the phone, "I have a different call to make."

"You tampered with his memories," she immediately dug into the person on the other line when they picked up.

"Ojou-chan," was the drawn-out response she received, "hello to you as well."

"Don't screw with me Kid," she growled.

"Ooh, touchy are we?" Kaito laughed on the other side. "Yes, I erased his memory of his time here with me, and the time he was in captivity as well to an extent."

"Why?" She asked, the phone creaking under the force of her grip.

"Why not? Don't you think it's better that he doesn't have that traumatic experience?"

"You had no right to mess with his head," she snapped.

"Perhaps, but there's nothing to do now." She could hear the smirk in his voice. "Well, there's nothing I can do now. Is it really worth it to give him back those memories?"

"I will if I have to." She growled and Kaito chuckled.

"Yes, such an irritating ability you have. Altering the minds of whom you wish. If they are taken for a reason, they should not be returned. Do me a favor, don't try to return his memories to him. I will be the one to do it when the time comes and," Haibara shivered as Kaito's voice became dark, "don't send him back to the girl."

"I'll be the one to decide that," she frowned.

"I suppose." He was met with a harsh click as she hung up and he snickered again.

"Bocchama, was it really wise to return the young Shinichi back to Beika?" Jii asked from his side.

"It's nothing to worry about Jii-chan," Kaito smirked, "he will definitely return to me soon enough."

"How do you know?"

"I have given to him some incentive to do so, that's all."

Just as Kaito predicted, the little detective came to his heist the next night, the calling card he left sent a personal invitation to the boy. They confronted each other on the roof as they always did, the task force left behind in the complex web of traps he set up. They would be a while and he would take advantage of the time that he had.

"It's good to see you again, Tantei-kun."

Conan froze, his face morphing into one of confusion before he regained himself and a cool smirk slipped back onto his face. "You're slacking KID, the traps were too easy."

"Did you think that maybe they were set up to be that way? Maybe I wanted only you to make it up here easily?"

Conan frowned as he stared up at Kaito, "why would you do something like that?"

Kaito jumped down from his perch and landed next to the small detective, "why? There are so many questions aren't there?"

Conan took a step back away from the thief but Kaito didn't let him go far. He gripped the detective's wrist and gave him a smirk, "Why would you do that? Where am I? Who are you?" Kaito pulled the boy closer and whispered into his ear, "What should I call you?"

Conan's eyes widened drastically, "y-you-"

"Do you perhaps remember what my response was to that innocent question of yours?"

"Ku-Kuroba Kaito." Conan shut his eyes tightly as his head throbbed.

"Yes, that is the unfortunate side effect of trying to fight my power," Kaito chuckled as he stroked Conan's hair, "it may give you a hellish headache."

"What are you saying?" Conan sighed as the throb subsided.

"I took the memories of your time with me, I didn't want you to come looking for me until the time was right. Would you like me to return them to you?"

Conan stared right into his eyes and Kaito tilted his head innocently, but then the sound of footsteps quickening toward them broke apart the moment.

"On this same rooftop, at the same time, tomorrow night, I will be here waiting for your answer," Kaito then leaned forward and pressed a chaste kiss to the small detective's lips and disappeared in a cloud of smoke.

Nakamori's team barged through the door and the little boy stared at the empty spot before him in surprise as he touched his lips.

The next night, Conan turned as he heard the thief land on the roof of the building the heist was held in the night before.

"You're early," Kaito commented lightly, "excited?"

Conan huffed as he turned his head away but Kaito could see the blush on his cheeks, "you told me you took something from me. I want it back that's all."

"Is that so?" Kaito approached the little boy and Conan looked up at him.

"And you left me with a lot of questions last night. I want answers."

Kaito landed on the ground with the boy in his arms. He put him down and changed his clothes with a snap of his fingers.

"So I take it, you know who I am?" Conan asked and Kaito chuckled.

"When we get to where we're going, I'll have an answer to every question you have."

Conan nodded and Kaito packed away all his stuff carefully as to not set off any smoke or glitter bombs. The glitter was so hard to get off and even harder to explain when he was caught with it coming off of him.

He picked up his duffel and held out his hand for Conan to take. The boy raised an eyebrow at him and Kaito did as well. "Come on Tantei-kun, make it believable."

Conan sighed and took Kaito's hand and they walked out of the alley toward the car where Jii was waiting, unaware of the surprised pair of eyes watching them.

Kaito slid into the car after Conan and he patted Conan's head before curving his hand behind the boy's neck.

"What are you doing?"

"You're going to take a little nap, I'll wake you when we get there."

"Wha-" Conan didn't get a chance to finish as he lost consciousness and Kaito laid him down across the seat.

"Go ahead," Kaito nodded.

"Yes, Young Master." Jii began driving and Kaito stroked Conan's hair as he returned his memories.

They arrived back at the Kuroba Manor and Kaito brought Conan in and put him up in the guest room he was in before. He sat down and shook the boy awake gently.

"We're here already?" Conan muttered as he sat up and Kaito chuckled.

"Yes, we're here already. How do you feel?"

"My head doesn't hurt so bad anymore."

"Yes, I'm sorry for taking your memories as I did. I didn't know how you would react when I decided to take you back."

Conan went silent and then he looked at Kaito with fierce eyes, "why did you kiss me?"

"Come now Meitantei," Kaito tisked, "it's not the first time now is it?" A blush formed on the detective's cheeks and Kaito chuckled again, "don't be so embarrassed."

Conan looked at his hands, "so what now?"

"I have a proposition for you."

Conan looked up at the thief curiously, and Kaito leaned forward.

"Become a vampire."
