Hello my lovely readers! I'm so sorry I haven't updated in what feels like forever... I am, indeed, what some people may call a "lazy shit". That, and I have had a huge writer's block for this story. Having heaps of ideas but not knowing how to write it is probably the biggest problem I have. On that note, I would really like to thank BakemonoShoujo for helping me with this, and so, I would like to dedicate this chapter to you~

And as an apology for the rest of you, I have made this chapter pretty lengthy. I have also started to write part two of my second story. So hopefully that will be up...eventually...haha.

.

After many years of exorcist training, it can be said that Yukio is considered to be rather stealthy. Despite this, the young doctor was still anxious as he slipped through the darkened halls of the abandoned dormitory with a moderate sized paper bag in his arms. He had always known that his older twin had sensitive hearing. Who knows how much more it has been intensified due to his condition! Sweat formed on the teen's brow. Every sound he made sounded like an explosion in his ears; what if Rin hears him? He needed to hide this bag somewhere out of the smaller male's reach...

"I am proud to announce that our scientists have discovered a possible solution—an antidote to Okumura-kun's condition!" Mephisto exclaimed from behind his grand desk to the young doctor. The young man opposite the older had his mouth hung open, completely surprised and unsure whether or not to believe the statement. The headmaster was well known for his mind games and generating false hope from people for his own amusement. Before being able to form a proper sentence in response to what he had just heard, the head master interjected.

"Though it's a possible cure, there is one problem." Mephisto commented as his eyes narrowed slightly. "We are not entirely confident that this cure will obtain the desired results, which is of course, returning Okumura-kun to 'normal'. So to speak." Ending his explanation with a smirk, never breaking eye contact with the younger Okumura. He continued, "Our scientists and some personnel who are in charge of this conducted research and development movement to find a vaccine have heeded a warning that effects may differ from person to person. As I have told you previously, we have never come into contact with such a problem as this case."

Yukio didn't exactly understand what the big problem was. Side effects? So what! How bad could they possibly be? As long as his precious nii-san is able to return to normal, there shouldn't be any problem. Though, as expected, curiosity killed the cat. "What may some of these side effect be?" Yukio inquired slowly. Mephisto grinned, as if he had predicted that very question being asked. "Enhancement of hormones, extreme and sudden bursts of strength, violent/abusive behavior, hyperactive behavior, confusion, possibly memory loss, and he may even lose himself for a short while." The headmaster answered as if there wasn't a single thing wrong with what he had said. His grin widened at the unimpressed expression on Yukio's face.

The elder demon handed the doctor four bottles, each being a different shape and size. As the young exorcist obtained the bottles, he studied the objects carefully. "Shampoo…and conditioner…?" The teen read aloud, slowly shifting his gaze back to the man in front of him, giving him a confused look. "Why yes, Okumura-sensei. You see, when applied to Okumura-kun's scalp, the substances and chemicals put into the shampoo will be absorbed by the root hair cells, sink into the scalp and will assist with the repair of his mental state!" He exclaimed in his matter-of-fact tone.

Yukio on the other hand was not convinced.

"With all due respect Pheles-san, do you really believe that shampoo will cure my brother's psychological state? What supernatural force could cause such an occurrence?" The young teen deadpanned. The headmaster shrugged. "Magic." He answered simply with a wink. Yukio struggled to keep a straight face. His brow, and the corner of his mouth twitched; a tick forming on the corner of his forehead. The teen still had to keep his temper, and hold his tongue. No matter how ridiculous this man was, Mephisto was still his superior, and thus Yukio had to keep his calm façade. Of course, Mephisto could see him struggling and loved every moment of it. It was a rare sight witnessing Yukio lose his cool.

"Anywhooo~" The headmaster started, "That aside, the other two bottles are medication that Okumura-kun must take twice a day. One is in the form of a liquid, and the other bottle is pills. It doesn't matter which you give him first, as long as he takes them both each day. The instructions are written on the bottle in regards to how many mL of liquid, and how many pills to give him." Mephisto explained with an unusually stern tone. "I understand." replied the younger.

Just as he was about to make his exit, Mephisto added, "May I advise you to hide those bottles from him, it would be wise to keep them out of his reach and administer his intake discretely…" Yukio didn't even have to ask him why. Ever since they were children, his older twin had been a pain when it came to taking medication. He was the type who would argue the point that his body was fully capable of healing on its own, and did not need the aid of ill tasting medication to feel better.

After the young exorcist had left the room, Mephisto added, "If little brother takes too much medication, he might be a little too much for Okumura-sensei to handle…" he chuckled to himself darkly.

On this trip back to the dorm, Yukio began to think through possible places to hide his brother's treatment. Somewhere his brother would not be able to get his grubby little hands on them.

…Well, honestly, it wasn't particularly difficult to think of a place to hide Rin's medication. It's not like the older demon was tall enough to reach most of the shelves anyway. Yukio nodded in amusement as he recalled a humorous memory of his brother desperately attempting to stretch, on his tippy toes, to reach the manga book that Yukio had placed on the top shelf to prevent him from being distracted while studying. Truth be told, Yukio didn't understand why Rin didn't just use a chair to stand on and obtain the book.

The young exorcist smirked to himself as he reached his dormitory entrance. That was definitely his brother's "manly pride", he thought to himself fondly as he entered the darkened halls.

A soft meow coming from a dark corner made Yukio jump and almost drop the bag. Snapping his head in the direction of the sound, praying quietly to God almighty that it was not Rin who was going to emerge from the dark.

Creepy. Thought Yukio as he waited in anticipation, feeling exceptionally apprehensive.

There, from the darkness of the corridor, huge, yellow eyes glowed. A small, furry creature revealed itself from the shadows, staring curiously at Yukio. The moonlight gleamed on the creature, who wiggled its two tails and blinked at the teen before tilting its head to one side.

"Kuro…!" Yukio whispered in a mixture of relief and annoyance. The cat meowed in response, before releasing another series of meows. Yukio figured that the familiar was obviously trying to communicate and tell him something, but the message did not reach his round, human ears.

Yukio slowly knelt down and placed a finger to his lip. "Kuro…! Shh… Quiet down, we might wake nii-san." Yukio said in a low tone. In response the familiar halted, stopping whatever it was trying to say and gave an understanding nod. Not wanting to wake his master, Kuro meowed no more. Yukio continued on to his room (with Kuro following close behind), and upon arriving he paused in front of the door. The cat sith peered up, confused, at the young doctor, changing his gaze from the door, to the teen, to the door, to the teen, and repeat. Yukio took a deep breath, last time he tried to sneak into his shared room after coming back late; his brother tackled him.

Well, it shouldn't happen again. Yukio had told him not to wait for him before he left after all. Quickly shaking off his doubts, Yukio slowly turned the doorknob and pushed opened the door. Unfortunately, once he stepped into the room he was indeed tackled to the floor, the paper bag flying out of his grasp and landing quite some distance away from him. The victim groaned and stared up at his attacker who was on all fours over his body.

"YUKIO~ I've been waiting for you!" giggled the blue-haired teen as he leaned down and pressed his lips against the other. The older-but-smaller teen began to move his lips against the other teen's lips, really seeming to enjoy the contact. Yukio however, was not amused. Though he had to admit this was kind of sweet (in a strange way), his gaze was focused on the paper bag a few feet away from him. Rin appeared to be oblivious to the existence of the bag, and moved his hands to cup each side of Yukio's face, pressing his lips harder against the younger's.

Well. It's game over for Yukio now. He really should've known better and gone with his initial gut instinct. Maybe it would have been better if he hid the bag some where in the kitchen. How on earth was he supposed to get himself out of this mess without alerting the older teen about the bag? Surely, if he pushed the smaller boy off him, he would definitely look up and notice the bag. Knowing his brother, his curiosity would get the better of him; he would bolt over to the bag to examine it, and everything inside it.

With a sigh, Yukio gripped each side of the boy's shoulders and rolled over, disconnecting the kiss. Rin produced a yelp that sounded like a mixture of delight and excitement. With his hands still gripping the boy's shoulders, which were firmly planted on the ground, Yukio whispered playfully, "I thought I told you not to wait for me tonight, nii-san." knowing Rin could hear him with their faces mere centimeters away.

"W-Well, I tried to go to sleep like you said! I swear! B-But I really missed you a-and I even tried sleeping in your bed, with your shirt on see-" the boy yanked up the oversized black T-shirt he was wearing to support his point "-but I was really worried and I wanted to see you come home for myself! So I was sitting on your bed waiting for you and yeah I'm happy that you're home now!" Rin explained quickly, hyperactively even. Throughout the whole speech, Yukio kept glancing at something, (he found it pretty awkward that Kuro was watching them) which caught the smaller male's attention. "What do you keep looking at, Yuki?" Rin questioned, turning his head towards the direction the other boy was glancing at. Turning back to the taller teen with a low growl, the smaller boy shoved the larger teen away, sat up, and snapped his head back to the direction that followed the other boy's gaze.

There, sat another cat. Yukio could almost hear his brother screaming internally. He was indeed the cruelest man on earth, and hoped that his nii-san could find it in his heart to forgive him one day. Using his curiosity against him, he knew his brother would react this way, and he felt a little guilty for doing this. Just a little.

Rin turned his tear-filled gazed back to his brother. "Y-You…I…" Rin began, not knowing what to say exactly. "Y-You're cheating on me? Yukio…Y-You… Why?" Rin asked in a shaky voice, his ears down casted. Yukio extended his arm and placed his hand on the boy's head, causing him to whimper and flinch at the contact. Soft sobs and hiccups began to arise from the smaller. The young exorcist snaked his arms around the crying exwire's waist and guided his head to rest on his chest, gently stroking his soft blue-black locks and fondling with his sensitive cat ears.

"Shhh, nii-san. Shhh." He cooed, still caressing the other. "Don't you remember? That's Kuro! He's your friend." Yukio exclaim with fake happiness, desperately hoping his brother would focus his attention on the furry creature rather than the paper bag that still appeared to go unnoticed in the opposite direction. He didn't exactly know why he made such an effort just to hide the paper bag. Perhaps he knew deep down inside that unexpected and troublesome things would come if the contents of that bag were revealed.

"F-Friend?" Rin repeated. "S-So you're not having an affair?" he asked slowly, his huge, ocean blue eyes staring into the other's soul. Yukio smiled gently and nodded, his brow twitching slightly. Kuro was a cat… how, and why would he have an affair with a cat. He pondered for a moment… perhaps his brother felt this way because of his condition. Animals generally dislike their territory being trespassed by others. Then again, Rin never really liked people touching or poking around at his stuff to begin with.

In an instant the teen's tears vanished, his ears perked up, and he flung his arms around the other's neck in a bone-crushing hug. The smaller male rubbed his face against the other's, all the while purring and mewling with happiness. Yukio laughed nervously. Due to Rin's current condition, it really did appear as though the exorcist had an oversized pet cat. As if one wasn't enough (he quickly glanced over at Kuro). From the corner of Rin's eye he saw Kuro and turned his attention to him, pulling a face and mouthing the words "back off" and "mine" all the while still clinging to Yukio. Not that Kuro cared that much anyway (he had always only really admired and adored his master - Rin. Yukio didn't interest him, except if Rin was involved).

GROOOOOOOOOOOWLLLL

Rin paused for a moment, ears perked up, and eyes wide. He loosened his embrace and retreated slightly. "Y-Yukio… did you hear that? W-What was that?" He asked, glancing up to Yukio's bright red face.

GRRRRRRROWLLLL

"Pfft…haha…HAHAHAHAHAHA!" Rin burst into laughter, rolling over to his side and clutching his stomach.

"Nii-san! Stop laughi-" GROOOWLLLL

"HAHAHAHAHAHAHAHA"

"Nii-san!"

"I-I HAHAHAH I'm sorry Yuki- AHAHAHAHAH! I-I'LL GO M-MAKE YOU SOMETHING TO EAT HAHAHA…." Rin exclaimed happily, still trying his best to hold in his laughter as he gave the other a peck on the cheek and trotted away.

"Stealing kisses from people is a bad thing, nii-san! It can be considered a crime!" Yukio called after the boy.

"What ever floats your boat!" Came the reply.

I guess some things just don't change. Yukio thought warmly to himself as he stood up and made his way to the paper bag. Once picking it up and checking if everything was still there and undamaged, which miraculously was the case, he followed after his brother down into the kitchen.

Upon arriving the young exorcist noticed the satanic twin making what appeared to be sandwiches. Yukio took his usual seat before reaching into the bag, taking out the two prescribed bottles and shoving them into his coat pocket, leaving only the "magical" shampoo and conditioner inside the bag. Before doing anything else, a certain stove-spirit-familiar-of-the-principal hopped onto the table.

"Oh, Ukobach! Hello!" Greeted Yukio. To which the demon squeaked a greeting in response. That's when an idea struck Yukio. "Hey, Ukobach. Would you mind helping me hide Rin's medication? It was given to me by Pheles-san." Yukio explained (the familiar nodded at him to continue). "If possible, could this bag be hidden on a shelf nii-san doesn't usually go to, and can't reach?" He added. The stove demon squeaked in acceptance and seized the bag, hopping off the counter and into the kitchen. Just as he was out of sight, Rin came out with two plates of toasted sandwiches.

"Eat up, Yuki~" Rin said energetically, placing down the two plates; one on his side, the other on Yukio's. "I'll be right back~" he added as he trotted back into the kitchen. Yukio quickly pulled out the bottle with the pills. "The affected must take two capsules everyday. Capsules must be swallowed with food, not whole." The teen hastily pinched the top layer of bread on his brother's plate, crushed the capsules, and sprinkled them over the ham and cheese before placing the piece of toasted bread back down.

Just as he had finished, the other came back with two glasses of milk. Once again, placing one down on each side of the table before taking a seat. "Nii-san? Would you mind getting me a knife and fork please? It's a bit too hot for me to hold and eat." Yukio asked politely. "Sure thing Yuki~" Rin replied, getting up once more and walking back into the kitchen.

This time, Yukio pulled out the second bottle. "The affected must drink approximately 40mL every day." Yukio calculated how much 40mL would be, quickly poured it into Rin's glass of milk and stirred it with the straw. Thank goodness the liquid was a clear colour, otherwise there would be some pretty bad complications.

Once Rin returned, the two ate together in a relaxed atmosphere, chatting away about how each other's days were, laughing, and enjoying Rin's delicious food. After finishing, Yukio insisted he'd carry the plates into the kitchen, telling Rin to sit and wait for him in the dining hall. "Ukobach…? Ukobach are you there?" He called. The stove spirit appeared before him. "Here are the other two bottles of medication, please hide them well Ukobach! Thank you for your help." Said Yukio with a smile. The demon squeaked and pointed to the top shelf behind the teen. "Up there?" He asked, to which the demon nodded in response. "Thank you very much, Ukobach!" Yukio repeated once more, reaching up and placing the two bottles next to the others. He bowed politely to the demon and made his exit.

Making his way back to the table, he noticed something off about the other. "Nii-san is everything alright?" He asked worryingly. The other just gazed up at him with glazed, dilated eyes. "I-I feel really weird, Yukio… My body feels hot…" Rin explained in a hoarse voice. Yukio really didn't like where this was going. "Now, now, nii-san. Perhaps you're coming down with a cold. Off to bed with you!" He said in a lighthearted tone. This way, it wouldn't be as suspicious if Rin found him holding bottles of medication. Precautions are always good.

"Carry me?" Rin asked, his eyes fixed on Yukio. The teen sighed. His brother sure did know how to push his luck. He decided to give into his brother's wishes. Usually he wouldn't do so, but he was especially desperate to get rid of the boy tonight. He positioned his arms under Rin's butt hoisted him up. Instinctively, the other hugged his legs around Yukio's waist; his arms around his neck, buried his face in the other teen's neck and gigged. Rin's body was heating up fast, and the fact that there was something fleshy and hard pressing against Yukio's stomach didn't thrill him all that much...

Aaaaaaaand I'm going to leave this on a cliff hanger! (I'm horrible, I know)

To smut or not to smut... It's so hard to neglect my OTP love for these two.
I just want to drop the whole plot and shout "THEN THEY HAD SEX". But I have willpower and thus, I will resist.

I'll leave it up to you guys, really. There's two ways this story can go tbh

Also, do my lovely readers prefer more lengthy updates like this one, or do you prefer shorter updates? Personally I love long updates, but I've seen some people say that they prefer shorter updates. So let me know your opinion :)
