My first Kuro fan fic ever. I've tried my very best. So be nice and give me reviews.

Disc: I owned Kuroshitsuji if I'm Yana Toboso. Which I am not. So I own nothing.

"This is gonna be fun…" A man with long silver hair chuckled lightly. After all, he hadn't made this potion for nothing…

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Ciel sat on the chair with a bunch of papers on his desk. To say the truth, he wasn't comfortable, especially when he can't sleep although he desperately need to. The nightmares. They have always hunted him, but this type is new and…weird.

Flash back

Ciel moans loudly. Sebastian has been teasing him nonstop. "Q..quick, Sebastian! I can't take it anymore."

"My my, such an impatient master you are." Sebastian chuckles. Then, he proceed to lick along Ciel's jaw line and bite on his neck, which makes Ciel hissed loudly.

"Se..Sebastian…" The young Earl mumbles.

"Now, let's the fun begin…" The demon smirks, slowly unbuttoning the boy's shorts…

" Yound master?" Ciel snapped of his day dream as his butler called him. "What?" "Undertaker's waiting for you." "Undertaker? He almost never left his place!" "Well then it must be something important, do you not think so Young Master?" Ciel sighs "I'm coming."

Outside the manor

"Undertaker, why are you here?" Ciel asked coldly. " Oh dear, I can't even see my favorite Earl? Well, I'm here to give you a small surprise." "A surprise?" "Yes, to warm you up. You have been, well, boring lately, havent' you? This would make things exciting. Specially for your butler." Undertaker said as he pulled out a pack of powder of some sort. "This is a type of very special tea. Drink it and have fun." Undertaker explained with a big grin in his face and walked away. Ciel lifted an eyebrown. "So what are you going to do with it, Young Master?" "It's the first time he has given us a present. I'll drink it. But tell me if there are poison." Ciel replied and walked back to his room. "Understood." Sebastian said and bring the "tea" to the kitchen. But after he finished making the tea, he let out a gasp. "This is…"

Ciel's room, after a while

*knock knock* "Come in." The door opened to reveal Sebastian with a tray on his hand, holding tea. "Is there any poison in it?" "No, Young Master." Ciel brought the cup closer to his mouth and sniff it. "Wow, it smells so good." Then he sipped it. "Nothing weird." He finished it and placed it back in the tray. Suddenly, a wave of sleepiness overcame him. "Se…bas…tian…" Ciel mumble as he dozed off, seeing a pair of red eyes stare at him." Sweet dream Master…"

Yub. That's it. Find out more in the next chappie~

Just kidding.

Ah…so comfortable… Ciel snuggled closer to his warm pillow. A hand petted his head. Ooh, it feels so nice. He let out a soft whimpers and clutched in the piece of cloth. The "pillow" let out a small chuckled and scratched his ears, which makes him purred in delight. Wait what? Ciel opened his eyes to meet him in an awkward position. He's been sleeping in Sebastian's lap.

His face turns crimson red and he jumped away. "What the hell are you doing to me? Nya." Sebastian smirked in return. "Why, pleasing you, Young Master. You seems to be very LIKE it." Ciel turns even redder ( which make Sebastian again smirked at the boy's cute reaction) " Shut up, nya! I'm asking why did I fall asleep so suddenly and wake up with these "nya" thingi, nya!" Ciel asked, both confused and embarrassed. Sebastian blinked. " You should look at the mirror for the answer, Young Master." Ciel walked to the mirror, and his jaw dropped. Holy shit! On his head is a pair of cat ears, and on his butt is a freaking cat tail! "WHAT THE *BEEP* IS GOING ON HEREEE?" He screeched. "Calm your tits down, Young Master. It's probably some prank Undertaker has made." Sebastian said, trying to keep his face straight. "Undertaker? You said there are no poison in it, nya. Why you…?!" "Slow down. There is no real poison in there. When I first sniffed it , I know there's something in it, but not poison. And when you slumbered, I though Undertaker is just making you dream some weird dream, which is good, since you're not sleeping a lot lately." He spoke. " Oh man, this couldn't get worse." Ciel still hadn't get over the shock. " Uh… actually it can, considered Miss Nina is coming here to make you some outfit." "WHAT?" As if to prove what he just said, the door bursted open and a running Maylene crawl in, followed by a groping-Maylene's-breast Nina. "Halo cutie! Ready to try some out…fit…" The whole room went frozen for a few minutes. "Don't. say. a word." Ciel tried his best to be serious but only to look like an angry kitten. " Oh my…" Nina slowly broke the silent and walking slowly forward. "YOU LOOK SO ADORABLE!" She glomps Ciel. " I can't believe you wear cat ears and tail for me. I'm so happy. Well then, I'll work my very best to make you the cutest outfits ever!" She said with fire of passion surround her. "YOU ALL PEOPLE GET OUT!" She shouted and close the door.

After quite some time

The door bursted open again (A/N: Poor thing) and stand there, is the moe-est catboy ever! His dark hair got lightly messy, his cheeks are pink and his face has a little pout. He wears a long-sleeve shirt, which exposed his shoulders and navel. His shorts are super-short that allowed him to show his beautiful pale legs. In his neck is a collar and on his tail is a ribbon. He wears a pair of high heeled boots that went up his knees. Ciel looked so…delicious, not to mention, tempting. The servants quickly covered their nose and ran to the nearest bathroom. "EXCUSE US". Sebastian seems to ready to break down any moments.

" Oh my, it seems like I have to leave now. Have fun." The energetic woman said and run out. Sebastian too busy stares at Ciel's creamy thigh to care.

"You can stop staring now." Ciel said, try not to sound nervous. " Oh, sorry Young Master." Sebastian lifts his eyes to look at Ciel. Ciel tried to avoid his eyes, for they make him nervous. He had quite a crush on Sebastian after all.

"So what are we doing now?" Sebastian asked. Ciel sighed. "What else but to meet the maker of these?Nya." He said with a irritated voice.

A/N: I REALLY WANT TO STOP NOW. BUT I'll CONTINUE THIS FOR YOUR SAKE. BE GRATEFUL!

Undertaker's shop

"Ah, welcome Earl." Undertaker said as if nothing has happened. "What do you mean by "welcome"? Look what you've done to me, nya!" Ciel mewed furiously and removed his coat and hat, show his revealing outfit and cat parts.

Time turns frozen for a while, before Undertaker laugh his ass off. " Oh my god…" he pants "I have never seen Earl in such a state before. I expected the cat parts, but I didn't think about the outfit." Undertaker wipes his tears. " It's not my fault my clothes ripped apart while I struggle to escape Nina's grasp so she has to take them to repair and leave me with a bunch of ridiculous outfits!" Ciel spoke with his face as red as a tomato.

"Okay, whatever you say. So, why are you here?" Undertaker asked. "WHY AM I HERE? THINK ABOUT WHAT YOU HAVE DONE TO ME!" Ciel screamed. "Calm down, jeez. You're not going to be harmed. The powder I give you is the new stuff I just made called Neko24. You're just going to be a catboy for 24 hours, that's all. But do aware that you might have some cats characteristics and abilities. For example, you like to drink milk than tea, to be petted than to be alone, and to be close to your owner…" He grinned deviously. "Wait, what owner?" The cat boy asked. "It's the person who's gonna take care of you, protect you. Who do you feel most attached to since you wake up?"

Ciel's face turned crimson. He has some weird deep feeling to Sebastian since he woke up. It's still the same as how he view him as his crush, but since he's a catboy, he feel admired the man than ever. "Me." Sebastian replied bluntly and Ciel turns around, but say nothing. "Then he would be your master." Undertaker said simply. "Wait, why would I need a Master? Nya."Ciel protested

"Because you have no selfcontrol. The person who wanted to kidnap you just have to offer you some milk, and you'll gladly follow him/her." Undertaker answered. Ciel snorted. He can't argue with Undertaker, can he? He's the one who makes the potion after all. "But what about our contract?" "Well technically you're still his Master. But for this 24 hours you should listen to what he said."

After a few moments, Ciel snapped grumpily: "Fine. But only for 24 hours. And he can't force me doing anything." Ciel stomped out the store, follow by Sebastian, who flashed Undertaker a smile in which the silver haired man only grin in return.

On the carriage

"Now now, don't be like that. This is an accident. I'll take good cares of you." Sebastian tried to hide the amusement in his voice, only to have the boy give him his oh-so-called-deadly-glare. "Be a nice boy, and I'll give you some fish…" He turns his head toward Ciel and smirks "Kitten."

This is going to be a loooooooooooongg day.

Finallyyyyyyyyyyy. This took me almost 3 hours. Be extremely grateful. Now how about some reviews so I can update the next one faster. Spoiler: Lemons in next chapter~
