A/N: This will be my last update before school starts. Then updates will come slower and I'm sorry! But I know that I'll be busy but I'll try my hardest to update as soon as possible. Also, frankly, I'm shocked at the lack of my favorite stories. It makes me sad... So that's another reason why I'm updating mine!

So please enjoy and review!

A Mistake is a Mistake is a Mistake

WARNING: Crossdressing, sucky battle scene, and KandaXAllen smut ahoy!

"So tell me, Lavi."

The boy held a very stern gaze at his redheaded friend who was biting his lip.

"What is it, Allen-chan?" the redhead sang out gleefully and held his stomach to stop his laughs (and he was doing a pretty good job of it too).

There was a pause where Allen let out a small whine and chewed at the inside of his cheek.

He fidgeted and looked very uncomfortable.

"Is cross-dressing part of the school's curriculum because this skirt is riding up my arse," Allen pulled said skirt down and turned a bright shade of red. Despite that, he had an oddly serious expression on his face as if this was actually something to be considered.

At this point, Lavi could not keep the giggling fit in and pounded the table next to him as he was consumed by his laughter.

"Shut up!" the cursed teen whined. Behind him, a small snort could be heard. "And you too Bakanda." Allen hissed through his teeth.

"I-I'm s-sorry, Allen," Lavi managed between his bout of insanity.

They were currently at Allen's house after they had come home from picking up Allen's new uniform. And Allen was currently wearing said 'uniform' while slapping himself over and over again mentally. And Lavi, being the courteous and ever loyal friend he was, really was trying oh so hard to stop his snickering (and failing). Kanda was in a corner and chose not to comment…yet, but his face was a very warm shade of scarlet as the beansprout's skirt hiked higher on his thighs.

"It's not your fault," said white-haired boy sighed. "Although I can't understand why the school secretary gave me a girl's uniform."

"Maybe because you're short and skinny like a girl," Kanda supplied, smirking as he eyed the exorcist up and down.

"You're not helping, you stupid idiot," Allen muttered and glared at the corner where the samurai was observing this scene with an amused look on his face. This was so embarrassing and he knew that Kanda was not going to let him live it down.

"What did you say, Allen-chan?" the older teen finally ended his fit but kept his arms around his sides to stop the stitches forming there.

"Nothing!" Allen squeaked before laughing nervously. "Anyway, do you think that I can get another uniform?"

"I think it looks good on you, moyashi," the raven-haired man drawled. Allen blushed and decided to ignore him for the moment but his hands went unconsciously to his shirt. He wanted nothing more than to turn around a deliver a well-deserved blow to the swordsman's face.

"Erm…," Lavi tried to hold in his laughter but couldn't and pretty soon he was clutching at his sides and banging at the floor which he collapsed on.

"No!" Allen cried, "Why must I be cursed to look like a girl?"

"That's not the only thing cursed on you," Kanda muttered but the sides of his lips twitched upwards.

"And why the hell did I agree to wear this to begin with?" Allen voiced out.

"Because you thought the skirt was a pair of shorts," the red-haired boy choked out.

"Because you're stupid and naïve like that, moyashi," Kanda said at the same time.

"Shut up and stop calling me a moyashi! My name is Allen!" Allen screeched. Quickly, he clasped his hand over his mouth, eyes impossibly wide, but Lavi stopped and eyed his new cross-dressing friend oddly.

"I definitely heard that," he remarked. He put a hand around the shorter boy and poked the child's soft pale cheek. "So, who are you talking to, moyashi-chan? Is it a ghost?"

"No one, no one at all!" Allen frantically waved his hands in front of him.

Behind him, the cursed teen could hear Kanda's growl of annoyance when Lavi slung his arm around him. And the sound of a blade being drawn out. He was very positive he heard that.

"Lavi!" Allen threw the taller teen's arm off him and pushed him toward the door. "You err…. Go to school before me! I'll catch up as soon as I put something decent on."

"What's the rush, moyashi-chan?" Lavi questioned, confused and unaware of the danger he was in.

"Go! Now!" Allen gave an almighty shove and shut the door quickly. Just in time to because a second later, Mugen was planted next to Allen's head where Lavi would have been. Had the sword planted itself an inch toward the right, Allen would've needed an eye patch like the redhead.

"I don't like the stupid bunny," Kanda glared at the door and wedged his sword out from the wood. "His lunacy is going to rub off on you."

"You almost made me lose an eye!" Allen shrieked heatedly.

"But I didn't," Kanda deadpanned. Allen made a sputtering indignant sound before taking a deep breath to calm himself.

"Whatever," the white-haired teen grumbled. "I am going to go change out of this stupid uniform. Then I will go to school and be far away from the crazy samurai ghost who thinks it's fine to gut their spirit medium."

Allen stalked past Kanda but was shocked when a hand snaked out and grabbed onto the boy's arm.

"Kanda, w-what do you think you're doing?" Allen stared into those dark blue eyes that seemed to draw him in. A crimson blush spread over his cheeks and he unconsciously leaned toward Kanda.

"You look like a prostitute," the longhaired man whispered before smirking again.

"What?" Allen shouted before delivering a richly deserved punch to Kanda's face. And this was left hand, which packed more power than a normal human hand. Which meant that the Asian ghost was sent flying to the other side of the room.

Anger and embarrassment made Allen's face flush red and he stalked away to change mumbling curses toward Kanda under his breath.

The Japanese ghost stood up and touched his fingertips to his smarting cheek. He licked his lips excitedly. This boy was definitely something different.

School was fine for Allen. He had met up with Lavi all right and Lenalee who was the science professor's sister. They had become instant friends. His teachers were all very nice to him and he found his classes relatively well with the help of Lavi who had remarkable phonographic memory. Yes, everything was fine. That is, until his left eye whirred to life and turned from pale grey and white to glowing red and black.

It had acted up during his Physical Education period and he had fallen to the ground just when the soccer ball was flying toward the net… and toward his head. It went without saying that Allen had a good excuse to leave, which he took immediately.

He bolted toward a general direction and clapped his hand over his eye when it pulsated more fiercely.

"The only time my eye has ever hurt this much was…" Allen murmured before a boom made the ground beneath him buckle and shift. An akuma. But not just any akuma. An akuma made by the lost soul of a ghost who had not moved on with the help of an exorcist. They were the hardest to handle and the most difficult to exorcise.

He searched around and saw smoke coming from one of the buildings.

"The science department," the cursed boy mumbled before a thought hit him, "Lenalee! Lavi!"

He ran to the source of the crashes and soon found was he was looking for. Purple fire engulfed a pure white substance that was slowly being devoured by its own sorrow and misery. The poor soul was flying overhead with a rusted chain attaching it to the form of akuma it was taken. He shuddered as a cold feeling crept up his spine. He hated seeing the souls in agony. It tore his own heart apart to see such sorrow.

It spurred him faster and he entered the broken ruins of the building. Students ran to the opposite direction, screaming as teachers tried to calm them down and run in an orderly fashion (a lot of good that did).

"They're missing two students," Allen heard as he ran in toward the site of the loud banging. "A girl and a boy are still in there."

"Yeah!" another student spoke up, "I heard that too!"

"The science teacher is in hysterics because it's his sister," the first student said, "I hope they're okay."

"It can't be," the white-haired boy pulled off his white gloves. "Innocence activate."

His red scaly arm transformed into his anti-akuma weapon and he raced forward.

"Level two," he muttered as he eyed the gigantic deformed monster. Two bodies were huddled under a few of the tossed tables. From his line of vision, Allen could see that one was Lavi and another was Lenalee. They both seemed to be alive still so he turned his attention back to the akuma.

His eyes widened.

"Kanda?" Allen watched the raven-haired man battling the akuma. His sword was glowing silver instead of the usual coal black.

"Moyashi?" the ghost turned the merest inch to look at the cursed teen before turning back to fight.

"My name is Allen!" he snapped automatically.

So that was why people could see the sword, Allen thought as he jumped up and sliced the demon with his claw-like arm. Because it's an anti-akuma weapon.

This certainly explained some things…

It wasn't working. His arm wasn't cutting through the tough armor of the akuma. He glanced at Kanda and saw that at least he was making some progress, slicing through the akuma. His arm transformed itself into the second stage and fired a blast of bullets at the creature. It worked but Allen was exhausted and he needed to end this quickly.

"Rest in peace," he spoke softly as he delivered the final blow, and smiled. The soul was set free.

"Thank you, fellow ghost and sir exorcist," The ghost overhead whispered and left for eternal peace.

"Beansprout," Kanda spoke up after the other ghost had left. "What in God's name was that thing?"

"That was an akuma," he took a deep breath and explained quickly, "And you have Innocence." He de-activated his and pointed to the sword. "That's why people could see that sword of yours."

"Allen-kun?" Lenalee got up from the ground and winced. Her legs were cut and bleeding. Allen turned back to his two classmates.

"Lenalee!" the younger teen knelt down to help her up and pull Lavi out. "What happened?"

"The ground just suddenly fell on us and part of the building was torn up," the redhead groaned as he rubbed his back. "And the funny thing is that it looked like some unknown force was doing it. What the hell was that about?"

"You probably hit your head on something. It was just an earthquake," Allen laughed nervously. They can't see the akuma. They were ghosts before so of course they can't see it.

Lavi touched his head gingerly. "Must of hit my head pretty damn hard to imagine that."

"Let's get you to the infirmary," the white-haired teen nodded and helped Lavi up with Lenalee's assistance. He helped both teens to stand up and limp to the hospital wing.

Allen turned around to see if Kanda was there but the Japanese ghost was already gone.

The cursed exorcist sighed in peace as his back touched the couch. His bag dropped to the floor and he kicked off his shoes. It felt good to just lie around and do nothing after a good day's work.

"Moyashi," Kanda woke him up from overhead.

Allen groaned and put his arm over his eyes.

"Not now," he whined. "Can't it wait until tomorrow?"

"No."

"Go away."

"No."

"Please?"

"Just get up, you stupid beansprout!" Hands clasped around his shoulders and shook them.

"No," Allen replied stubbornly and sat up abruptly. Unfortunately, he didn't realize that Kanda was sitting (straddling, depending on how you looked at it) on him and his head connected with the taller man's in a very painful head butt. The very close skin-to-skin contact made Kanda's skin burn and tingle pleasantly.

As a ghost, he was devoid of all feeling. Meaning he couldn't feel warmth, coldness, touch anything and actually feel it. That came with the package of being dead. But he had felt something when he touched Allen's skin. It felt... nice and he wanted more.

"Bloody hell," the smaller boy shivered, rubbing the sore spot. Ghosts always felt cold to the touch and Allen always avoided skin-to-skin contact when it came to dealing with them (hence the white gloves on his hands). And usually, ghosts got very... touchy-feely when they had their first contact with warm human flesh. "That hurt, Bakanda."

Hands embraced him tightly and deftly peeled backed the jacket he was wearing. It fell to the floor in a heap. Allen's mind went into panic mode. What was the raven-haired man doing?

"K-Kanda?" Allen squeaked and turned a dark shade of red when cold hands lifted the sleeves of his button-up shirt. A small groan escaped from the older man as he picked up Allen's hands and ran it over his cheek. It was addictive and he hungered more contact. "Kanda, stop this-ack!"

He was pulled flush up against Kanda who could feel the heat emanating from beneath the thin piece of clothing. Allen stared into the sharp navy blue eyes clouded with an emotion that he could not decipher. He felt himself being drawn in and submitting to whatever emotion that Kanda had released for him to see.

Allen shivered from either the feeling or the cold (he honestly couldn't tell anymore) as Kanda ran his thumb over the scar above his eye. Why wasn't he stopping this? Why was Kanda doing this? It was more than the usual want of skin contact. There was something else there that Allen sensed. Could it be...? All thoughts flew from his head when he felt a hand slip under his shirt and ran over the small of his back.

"Moyashi," he whispered huskily.

"Kanda," Allen whimpered, his cheeks stained red. The raven-haired man pulled him closer by the waist and sealed the boy's lips with his. Allen's arms automatically clasped around the swordsman's neck, trying desperately to not fall to the ground in elation.

This was Allen's first kiss and it was hot and cold in a sense. Kanda's lips were soft and caressed his so gently but it was like kissing ice. Allen didn't mind that since the older teen seemed very experienced and knew what to do to get a reaction out of him.

A jolt of electricity ran through Kanda. It was great. It was exhilarating. And for the first time in 200 years, he felt alive again. He tasted the honey milk flavor that came with Allen and he smelled the soothing lavender scent that clung to the boy. Normally he detested sweet things but Allen was beyond that. Allen was his euphoric heaven.

His arms wound around the cursed child's waist and wrapped him firmly in a loving embrace.

"Kanda," Allen murmured between their lips but was silenced again when Kanda's tongue delved into his slightly parted lips. He ran over every part of Allen's mouth, memorizing each and every dip and curve of the orifice. The smaller teen moaned and pressed against him. He continued to the plunder the willing boy until Allen ran out of air and was forced to part. Allen's lips were bruised with the searing kisses that Kanda placed upon them and his quivering knees threatened to buckle under him. The albino let out a small whine at the loss of contact.

Kanda didn't stop but instead his lips went to the child's neck, trailing kisses and occasionally licks from Allen's chin to his collarbone. His head lolled to the side, allowing more skin for the Japanese man to devour.

"Kyaa!" Allen squeaked when Kanda licked a particularly sensitive spot. He smirked into the boy's skin and bit down, piercing the soft, supple skin and inciting a cry from Allen, which spiraled into a moan of pleasure as Kanda licked away the blood tenderly. It was hot and tasted sweet to his lips whereas for Allen, Kanda's tongue cooled his burning skin.

Allen's low pants enthralled the raven-haired man and he craved more. His hands went to the boy's collar and pulled opened the first button. Allen was too dazed to notice until the last button was popped open and his upper body was exposed to the cold air.

It was like his head was suddenly cleared and his face grew even redder as he realized what was happening. The ecstasy almost slammed Allen back into a stupor when Kanda licked the shell of his ear slowly but he resisted the urge to call out the samurai's name.

"Hyaa... W-Wait!" Allen panted as the man's lips slid lower. He pushed against the other man's shoulders weakly, drained of all energy. "S-Stop it! Ngh... I-I'm not ready yet!"

"No," Kanda mumbled against the flat plain of Allen's chest. A rush of heat invaded his being, leaving him breathless and gasping for air. He tried to pull away but the raven-haired man kept him in place, large hands on the boy's small hips.

Allen was at a loss of what to do. He steeled himself and pushed himself away as hard as he could. Somehow, he managed to escape and ran up the stairs, shamefaced and refusing to look at Kanda.

Had he glanced back, he would see the broken look on the swordsman's face.

A/N: Yes, I am evil to stop at a crucial point like that but all in good time. Also, this was my first attempt at some smut so please be kind.

Relax peoples. Kanda's not going to eat Allen just because he feels nice. Not yet anyways. Fufufufufu…. Please review if you liked it!
