A/N: What does the title mean? I really have no idea. And why is this categorized as Horror? Because it's so horrifyingly bad. Ah. Ha. Ha. Ha. I'll excuse myself now.

Shinichi's House

"Shin-chan! Shin-chan!" the voice called, followed by a knock on window.

Shinichi looked up from his book. It was Kaito and he was standing on the balcony of the house for some reason.

"Kuroba?! The heck are you doing out there?" Shinichi exclaimed. He stood up, annoyed, and stomped his way to the window, opening it and letting the teen in.

"Shin-chan!" Kaito yelled, leaping onto Shinichi and knocking him over onto the ground. They ended up on top of each other. "I came to visit."

"That doesn't explain why you didn't just use the front door, you know, like a normal person."

"B-but," Kaito stuttered, giving Shinichi puppies eyes, "What if someone saw me?"

"Ha? Wouldn't you be more noticeable climbing in through the fricken window?" Shinichi asked, a deadpan look on his face, "And besides, why does it even matter that someone sees you?"

"People will get the wrong idea about us," Kaito mumbled, looking away.

"Oi! Why are you blushing?!" Shinichi exclaimed.

"Because...Shin-chan's touching my-" Kaito started, looking down between their two bodies.

Shinichi followed Kaito's gaze, for the first time realizing where his hand had found itself. Shinichi blushed, quickly shoving Kaito off himself.

"Oh, and now who's the one blushing?" Kaito asked, a mischievous smile on his face. He leaded back so that he was sitting against the wall.

"B-baro! Why are you here anyways?" Shinichi remarking, diverting his eyes.

"Well, you're getting married to Ran-chan soon, right? I'm here to throw you a bachelor party!" Kaito exclaimed, jumping up in excitement.

"Bachelor party?" Shinichi asked skeptically.

"Yup! Look what I brought!" Kaito said, pulling out a bottle of sake.

"Where were you keeping that?" Shinichi asked. Kaito was wearing a plain orange T-shirt and shorts, with seemingly no place to hide the bottle.

"Do you really want to know?" Kaito asked, giving Shinichi a sly grin.

"On second thought, never mind."

"Eh? That's no fun," Kaito pouted.

Shinichi just sighed. "I have a lot of stuff to prepare for the wedding, so-"

"B-but, but, bachelor party," Kaito said, looking as if about to cry.

"Okay, okay," Shinichi conceded, sighing again. "But just until Ran gets back."

"Yosh! Leave it to me!"

"So, what did you have planned?"

"This," Kaito said, pulling out a deck of cards.

"Poker?"

"Stripe poker."

"As if!" Shinichi said, slapping the deck away and letting the cards scatter all over the floor.

"Eh?!" Kaito pouted, "Then what about this?" He pulled out a twister mat.

"Why are there pictures of naked people on the box?" Shinichi asked with a deadpan expression.

"Hehe," Kaito grinned, causing Shinichi to snatch the mat away and throw it out the window. "Are you sure you wanted to do that? People will wonder what you're doing with such a naughty game," Kaito said.

"It's your game!" Shinichi replied, falling back down on the ground. "I can't take this. Just do what you want. I'm taking a nap."

"Do what I want? Are you sure about that?" Kaito asked, instantly moving himself on top of Shinichi. Their faces were a few inches apart. Shinichi could see the dark pupils of Kaito's eyes, surround by blue irises. "Are you sure?" Kaito asked again, moving his face even closer.

"K-kuroba, wait," Shinichi stuttered, suddenly feeling hot all over.

"Eh, but you said, Shin-chan," Kaito whispered, their noses practically touching, "I'm going to do it, Shin-chan. Prepare yourself."

"W-wait," Shinichi mumbled. But even as he said those words, he could feel his eyes slowly drifting shut. However, what came next wasn't all what he was expecting.

Kaito quickly leaned in, stuck out a tongue, and licked Shinichi on the nose. Shinichi's eyes instantly shot open.

"What the heck are you doing, Kuroba?" Shinichi asked, giving Kaito an annoyed look. He used a hand to wipe the saliva off his nose.

"Hm, were you expecting something else, Shin-chan?" Kaito asked, the mischievous grin back on his face. Shinchi quickly blushed.

"B-baro," he mumbled.

"Oh, you were, weren't you? You were totally thinking of doing something naughty with me!" Kaito exclaimed, a gleeful expression on his face.

"Go screw yourself," Shinchi said, giving Kaito a harrumph and looking away.

"Ehhh?" Kaito remarked, "I didn't know Shin-chan was into that kind of stuff."

"Ha?" Shinichi asked, turning back around. Kaito was in the middle of standing up.

"But since it's Shin-chan's bachelor party, I guess I can do it," Kaito said as he began to take off his shirt.

"W-wait! Why are you undressing?" Shinichi asked in surprise.

"You just said-" Kaito began.

"It was a figure of speech!" Shinichi interrupted.

"Oh, is that so?" Kaito asked, putting his shirt back on.

"No good. I can't keep up," Shinichi groaned, plopping himself on the nearby bed.

"Shin-chan, you're like an old man," Kaito laughed.

"And you're like a little kid," Shinichi retorted.

"Maybe," Kaito shrugged, looking around the room for something fun to do. That's when he noticed the candy on the desk. "Oi, Shin-chan, you've been holding out on me," Kaito said.

"What are you talking about?" Shinichi asked, lifting his head up just in time to see Kaito popping something into his mouth. "Wait, baka! That's not candy!" Shinichi exclaimed, but it was already too late.

All of a sudden, Kaito began shrinking, becoming smaller and smaller, until he was the size of a seven year old. "Whoa! Everything suddenly got so big!" Kaito exclaimed, trying to move around in his now oversized shirt.

"That's because you got smaller," Shinichi sighed, "You just took a prototype de-aging drug that was developed from the APTX4869."

"Oh, I see," Kaito said, looking at his newly de-aged body. Then turning to Shinichi, he said, "Ne, Otousan-"

"Why are you calling me your father?!" Shinichi exclaimed.

"Ojisan?" Kaito corrected.

"Wrong!"

"Oniichan?"

Shinichi just sighed. "Sure, whatever. What do you want, Kuroba?"

"Oniichan," Kaito began again, "I need to pee."

At that, Shinichi couldn't help but chuck a nearby pillow at Kaito, hitting the boy square in the face.

"Ittai!" Kaito exclaimed, falling backwards, "What was that for?"

"Only your body shrunk! You can still go to the bathroom yourself!" Shinichi yelled.

"Oh, I see," Kaito replied, "Then does Oniichan want to take a bath together?"

"Shine!" Shinichi said, hurling another pillow at Kaito.

"Ehh? You're no fun at all, Shin-chan," Kaito said, standing up. His over-sized clothes dragged along the floor as he walked. "So how long is this supposed to last for?"

"No idea," Shinichi shrugged, "It hasn't been tested on humans yet."

"So I'm the first then," Kaito point out, "Well, at least help me find some better fitting clothes."

"Fine," Shinichi sighed, wondering how his day had ended up like this. Eventually, they found Kaito some children's clothes from when Shinichi was little.

"So, how do I look?" Kaito asked, tying a towel around his neck like a cape. "Pretty cool, huh?"

"What are you, five? Actually, now that I think about it, that body probably fits your brain much better."

"That's mean," Kaito pouted, "You're just jealous because you don't have a cape, you boring old man."

"Hai, hai," Shinichi replied, shrugging Kaito off, "Still, you're taking this whole thing rather calmly."

"Ma ne," Kaito said, "What's life without a few hiccups? By the way, when did you say Ran-chan was coming back?"

Shinichi looked at the clock on the wall. "Any minute now," he said. As if on cue, there was the sound of the front door being unlocked. "Guess she's back."

"I wonder if she'll think my cape is cool," Kaito said, adjusting the towel on his neck.

"I don't think that's the first thing she'll notice," Shinichi said with a sarcastic laugh. He got up off the bed, about to go greet Ran. Kaito followed behind. They got to the door of the room before Kaito suddenly started groaning.

"Ne, Shin-chan, I don't feel so good," he said, gripping his chest.

"What?" Shinichi asked, turning around. Just then, Kaito stumbled, falling forward. Shinichi instantly moved to catch him. "Kuroba, are you-?"

"I feel hot, Shin-chan," Kaito said as his body began to suddenly grow right in Shinichi's arms. The sound of clothes ripping could be heard as Kaito's body exceeded the size of the child attire. Before long, a fully grown, and half-naked, Kaito was lying in Shinichi's lap, fast asleep.

"You're really are just like a little kid," Shinichi remarked, patting Kaito on the head as he heard Kaito's soft breathing. Just then, the door to the bedroom opened and Ran walked in.

"Ah Ran, okaeri," Shinichi greeted, turning his head.

"S-shinichi, what kind of fetish is that?!" Ran exclaimed when she noticed Kaito. Her shout also caused Kaito to wake up.

"What?" Shinichi asked, for a moment not understanding what Ran was saying. Then a light bulb went off. "W-wait, Ran, it's not what you think!" he quickly said.

"Hmmm? And just what am I thinking?" Ran asked, crossing her arms across her chest, a bemused look on her face.

"I, that is, um," Shinchi stuttered.

"Well?" Ran pressed.

"This is just a misunderstanding! A big misunderstanding!" Shinichi exclaimed.

Still on Shinichi's lap, and having heard everything, Kaito couldn't help but let out a smirk. "Happy bachelor's party, Shin-chan," he whispered.

A/N: I don't think I pressed backspace even once. And I don't plan to! So ha! Take that grammar! Anyways, let me know what you think or...you know...don't.

Cheers! Peace!
