Chapter 9 – Clash of Lunarium

"To prove this we are going to have a test, if you fail I leave, if you pass I will stay," explained Aaron.

"What's the test?" questioned Simon

"You will all fight me...simultaneously," deadpanned Aaron before smiling and walking out of the room.

The next day Aaron stood in the middle of a large clearing in the forest. He had left a note on the table telling them to meet him here at twelve and then left. He had already been awake for six hours and had spent it all here. Using his powers he had created a barrier around the area to make them invisible to anyone who might see or sense anything. Then he had used one of his newer runic wards to create a powerful multi-void-barrier that would absorb anyone with the slightest Taint that approached.

Aaron didn't want to admit it but he was worried. He knew he was far more powerful than the Sevilles even if they worked together, but he still wasn't sure he could defeat them. If they worked well together they could easily stop him before he had a chance to do anything. Sighing, Aaron wondered what would be so bad about losing and staying with the Seville's anyways. Aaron's eyes widened and he ruthlessly crushed that line of thought.

He was dangerous and he wouldn't put the Sevilles in danger. He would win this fight no matter what it took. Turning around, Aaron crossed his legs and sat patiently in the middle of the clearing. Black lunarium began to circle around him as he summoned it from within himself. As he concentrated, more and more power appeared until the air around him was so thick with it the trees were groaning under its weight.

He would not lose...

Back at the house everyone was preparing in their own special way. In the living room Simon was reading the guidebook and Aaron's journal to refresh his knowledge and maybe find something that would help in the fight, but at the same time he was honing his control of lunarium by holding himself and the books in the air. He didn't care how much danger they would be in if Aaron lived with them. Aaron was family and they were going to bring him home.

In the kitchen Theodore was cooking in a human form with a smile on his face. He hadn't touched lunarium all morning, well except for learning to transform, and wouldn't until he had to fight. He was already as prepared as possible and he knew that no matter how much last minute stuff he did it would not make any difference in the coming battle. Aaron would be able to easily wipe the floor with all of them. They would stand no chance no matter what they did. But somehow even with those thoughts in his head Theodore never stopped smiling.

They would get Aaron back no matter how hard it was. No matter how long they needed to fight or how much power they needed to use. Breathing in deeply Theodore pulled his cookies out of the oven. Aaron was family and they were going to bring him home.

Meanwhile just outside the house Alvin and Dave were practicing together. Both of them testing each other and driving their powers to new heights. Both of them wanted nothing more than to beat Aaron into the ground and drag him home. Screw the danger! It meant nothing to either of them. But Aaron did mean something to them. Aaron was family and they were going to bring him home.

The Chipettes watched all this with wide eyes. The bonds this family had with Aaron were nothing short of incredible. Though they had only seen him a few times and never really talked to him they found they understood. Aaron was family to the chipmunks just like they were family to them. The Chipettes found themselves wishing they could control lunarium. So that they could help the chipmunks and Dave bring Aaron home with them.

The clock on the mantle struck twelve...

Aaron stood calmly in the middle of the field as Dave, the Chipmunks and the Chipettes appeared in a swirl of red, blue, green and yellow lunarium. Turning around he motioned for the Chipettes to go and sit in the small stands he had created. They would hover over the field so the girls could watch what was going on without being in danger. Once the girls were comfortably seated and floating above them, Aaron turned and faced Dave and the boys.

"The purpose of this is simple. You must use all of your power, skills and teamwork to subdue me while I try and knock you unconscious," explained Aaron.

Dave and the boys nodded as their crystals began to glow. Alvin pulled his sword from it's sheath and in a blur of speed appeared in front of Aaron with it raised high. He slashed downwards with all the force he could and a trail of red lunarium flowed after the sword. With a resounding slam of force, the blade connected.

Dust rose up into the air as the ground cracked and a small crater formed. When the dust cloud disappeared, everyone's eyes went wide in shock. Standing in the middle of the crater was Aaron with his hand high in the air wrapped around the blade of Alvin's sword. Alvin was being held in the air, his eyes wide with shock. Aaron shook his head in disappointment and with a flick of his wrist the blade shattered in two.

Alvin began to fall to the ground, the hilt of the sword falling from his hand before a foot connected with his chest and he was knocked backwards through the air. Dave caught him in his arms and they skidded back a few feet. Aaron lowered his leg and glared across the clearing as he dropped the part of the broken blade to the ground. He was slightly surprised that it had broken so easily but he tried not to show it.

"You're a fool Alvin, and your idiocy just cost you one of your most useful weapons," he said with a shake of his head.

Alvin flushed brightly but had no time to feel sorry for himself as Aaron appeared in between them all. A fist connected with Simon's face, followed by a foot and then a blast of energy. Twisting, Aaron slammed his elbow into Theodore's side before spinning and knocking his feet out from under him. This was followed by Aaron grabbing Theodore by the hair and hurling him across the field and into Simon who had been slowly getting up.

From there Aaron appeared beside Alvin and Dave. Both of them began attacking but Aaron seemed to flow around their attacks. Aaron slammed his head against Alvin's who stumbled back before being sent flying and crashing into Simon and Theodore. Dave gathered energy and charged forward. But seconds later he too found himself in a pile with his sons.

Aaron walked calmly back to the center of the field with a frown.

"If this is the best you can do you will be unable to stop me," said Aaron shaking his head.

Alvin, Simon, Theodore and Dave untangled themselves and climbed to their feet. Looking at each other they crouched into a circle and began to talk. Aaron watch dumbfounded. Did they really think an enemy would let them try and come up with a plan right in front of him? Sighing he gathered his energy, deciding he needed to knock some serious sense into this family. His black aura flared and pressure descended onto the clearing.

Black spears ripped through the air towards the group. Simon sensed them and pushed everyone apart just as the spears surged through the space where they had been standing. Before any of them could react they were greeted to the sound of Simon screaming in pain. All of them looked towards him and their eyes widened in shock.

Dark power circled around Aaron as he held a long sword loosely in his hand. But that wasn't what shocked the group. It was what the sword Aaron had created was plunged deeply in. Simon was clutching the blade of the sword and trying to steam the flow of blood from the deep wound. No-one could believe their eyes as Simon coughed loudly and blood splattered to the ground.

Alvin's eyes clouded with anger and he immediately charged forward recklessly. Aaron sighed and, using his power to cloud the sights of everyone, he ripped his sword upwards cutting Simon in half. Everyone stopped and the Chipettes started screaming.

"WHAT DID YOU DO!" screamed Dave

"You were unprepared for the challenge, and it has cost you," whispered Aaron hoping his voice remained firm.

Behind him Simon banged against the invisible wall that seemingly blocked him from being seen. It was obvious that Aaron knew what he was talking about but it seemed he hadn't yet noticed the look on Alvin's face. Only Simon knew the true depth of power Alvin could wield but it seemed that Aaron was about to find out.

Dave and Theodore continued to scream at Aaron in disbelief. He was about to knock some sense into them when suddenly he felt it. A power so intense and powerful that he had to check to make sure he wasn't unconsciously releasing power. When he realized it wasn't coming from him he glanced behind him to make sure it wasn't Simon.

Sure that it wasn't Simon, he turned back around and a fist slammed into his face. Aaron hurled through the air and smashed into a tree. Gasping he felt whoever the power belonged to appear in front of him and slam a powerful sphere of energy into his chest. Growling in pain, Aaron flew through the air and unleashed his own power. As power flowed through him, he caught his attacker's hand in his palm and slammed his knee into his chest.

With the power of a jackhammer he elbowed his attacker in the face sending them flying. Appearing over top of his adversary, he slammed his enemy down into the ground with a resounding bang. Breathing deeply, his eyes widened in shock as a figure rose in the massive cloud of dust the attack had created. A massive aura of red and silver power ripped through the dust and revealed his attacker.

Aaron's jaw fell as he recognized Alvin. Except something was wrong. Alvin's normally joyful eyes had turned a deep melted silver that glowed with barely suppressed power. All of Aaron's senses were screaming at him to release all his power. To stop holding back and attack with all his might. But for the life of him he couldn't bring himself to do it.

Alvin's aura rippled and flicked around him as he disappeared. Aaron's eyes widened as Alvin used a technique he hadn't thought anyone but him could do. Spinning, he blocked a kick at his head and in a blur of speed Alvin and Aaron started attacking each other. Aaron kept up with Alvin blow for blow but he could easily see Alvin was just getting more and more powerful.

Sighing, he pulled out more energy only to feel Alvin's suddenly jump to match. As the fight continued Aaron finally figured out what was giving Alvin such power. His body was flowing with silver lunarium that had before flowed through the sword he had given Alvin. It was obvious to him now why the sword had broken. Alvin had somehow subconsciously drawn all the power out of the blade and into himself.

But somehow Aaron knew that Alvin didn't know this. And judging by everyone's faces neither had Dave or Theodore. Simon didn't look as surprised except for when the silver in Alvin's aura had appeared. Simon must have known about Alvin's hidden power but must not have known what had given it to him. Jumping backwards, Aaron decided that he was finished with this. It was time to show the Seville's just why he couldn't live with them.

Power wrapped around Aaron as Alvin charged towards him. Alvin pulled back his fist and struck out fast as lightning, but Aaron was faster as he caught Alvin's hand and then quickly broke his arm. Pain flared through Alvin and his power instantly dropped back down to normal. But Aaron didn't stop as he pounded Alvin into the ground with a fist in the stomach followed by an elbow into the back.

Spinning around he blocked Dave's fist and broke his arm as well. He then tossed Dave carelessly over his shoulder and into the tree behind him. Dave slid to the ground unconscious and Theodore began to attack. Vines flew from within the trees, spikes ripped up from the earth, blades of air cut through the air, fire burned across the ground. Aaron blinked and raised an eyebrow. It seem Theodore's powers went a little beyond just controlling the earth.

But he wasn't going to be taken down by such weak attacks. With a slash of his arm a massive cresent wave of lunarium cut through the air destroying everything in its path. Theodore managed to move out of the way and continued attacking. Aaron sighed as he twisted and moved around every attack Theodore threw at him. He knew this fight was pointless. His power had no limits as his body wasn't anything more than a construct to hold his power.

He could reach levels of power impossible for anyone else. If they tried to match him one of two things would happen. Their powers would burn out and they would never be able to use them again. Or they would momentarily pass their limits and their bodies would be ripped apart by the power it gave them. Spinning, Aaron's foot slammed into Theodore's head and sent him flying across the clearing. Theodore skidded to a stop, unconscious in the dirt.

Tilting his head, Aaron watched as the barrier he had trapped Simon in disappeared. The Chipettes gasped in shock as a tired but alive Simon climbed to his feet. Aaron prepared to attack only to stop as Simon let his lunarium fade away. Aaron raised an eyebrow in confusion and Simon just shrugged.

"I can't win against you," said Simon with a sigh.

"Exactly, which shows that it would be far too dangerous for me to live with you. None of you understand anything. You use your powers like they're toys," scolded Aaron.

"Then teach us," replied Simon.

Aaron blinked in shock. Could he do that? Could he teach them all how to truly fight and use their powers? Aaron realized that he could and he knew he didn't really want to leave. He waved his hand and everyone found themselves suddenly standing in the Seville's living room with no wounds. Aaron turned around and headed towards the back door. Pushing it open he took a few steps before turning and facing Simon.

"I'll think about it," he said before vanishing in a swirl of black energy.

Simon smiled. That was good enough for him...

Aaron stood silently looking out across the ocean. He had transported himself as far away as he safely could without draining too much power. As he watched the waves crash together and fish splash in and out of the water he sighed.

He had been alone for a long time. Ever since his brothers had died. Could he really put the Seville family in danger with his presence? But then all of them, except the girls, had crystals already which put them in danger.

Aaron sighed and lowered his gaze to the ground. If he taught them they would likely become far stronger. The stronger they were the more likely they would be able to protect themselves. Dropping to the ground he sat on the white sandy beach and let his mind wander.

Did he dare chance it, did he dare hope for family once again...

Theodore lay back in his bed exhausted. Aaron had easily beaten them all and even though he was healed he was still tired. His energy hadn't been refilled and he felt as if he had just fought a hundred Tainted. He had known they would be unable to defeat Aaron but for him to be so much stronger than them was something he had never imagined. Looking across the room, Theodore's gaze locked on all the members of his family.

Dave, their father had stood beside them against Aaron. He had decent training but was nowhere near as strong as them. He had been defeated easily and likely felt he had failed his sons. He was tired and Theodore could see it in his eyes. Dave was losing his battle to see the happiness and good in the last few weeks. Turning his gaze Theodore looked at Alvin and Simon.

Both of them were cuddled together and looked drained. Ever since they had become a couple they hadn't had much time together. Every so often they kissed and hugged but that was it. Even Theodore could tell that it was killing them to be so close and yet so far from each other. When Simon had apparently been killed Alvin had shown an incredible power.

It had been far beyond anything Theodore had ever thought he would experience. Yet Aaron had still beaten him. Every time Alvin gained a boost in power Aaron's power would increase right with it. What hope had they stood against Aaron with his infinite capabilities of power? Sighing, Theodore wished he felt the same pain of loss Alvin had felt. Yet he knew he would never be as close to Simon and Alvin as they were to each other.

Theodore gazed over at the girls who were talking amongst themselves. They had sadly been dragged into the danger now that they lived with them. But unlike any of them they had no way to protect themselves and were constantly in danger. Theodore's gaze locked onto Eleanor and he wondered what she was thinking. He couldn't help but stare at her, she was so beautiful. Shaking his head Theodore quickly threw those thoughts aside, he couldn't afford to love right now.

Theodore blinked as Simon and Alvin stood to their feet and left the room. Both of them were muttering quietly to each other and Theodore couldn't help but wonder what they were doing when they headed up to the attic. Not really wanting to think about it, Theodore leaned back against the chair and sighed.

Maybe it was time to get some rest...

Simon and Alvin climbed the steps into the attic right beside each other. They talked quietly to each other, both of them slightly scared at what was coming. Entering the attic Simon walked right over to a large old mattress and jumped onto it. Alvin jumped up beside him and they looked into each other's eyes. No more words were said as they pulled into each others arms and kissed each other tightly. Neither of them rejected the other as their mouths opened.

= = = = = Mature Scene (Skip If You Don't Want To See) = = = = =

Simon and Alvin's tongues intertwined and began to explore each others mouths. Hugging and kissing tightly both of them blushed slightly as they felt each other. Heat flowing, they felt their bodies both react their private parts both hardening. They both felt each other stiffening but neither of them cared and just pulled each other closer.

Suddenly they tripped and fell to the bed wrapped in each other's arms. Quickly they found their clothing being ripped from their bodies. As one they pulled their naked bodies together and rubbed slightly against each other. Still no words were spoken as they both agreed to the silent proposition of what was to come. Crawling into bed Alvin rolled them as they pulled apart. The roll ended and Alvin found himself crouched over top of Simon.

"You sure you want to do this?" questioned Alvin.

Simon looked up into his brother's bright eyes and nodded. His brother hanging over top of him, their eyes looking into each other's and his arms beside his head. Alvin nodded and quickly grabbed hold of his cock and aimed it. Simon closed his eyes and braced himself as he felt Alvin pushing against his backside. Then he felt Alvin pick up his legs and he gasped in pain as he felt Alvin's cock shove into him.

His legs wrapped around Alvin as he felt himself pulled forward. An odd feeling extended from his butt and pain followed it. Yet at the same time it fell so good that he didn't want Alvin to ever pull out. But his wish was denied as Alvin pulled back, his cock slowly pulling out. Simon gasped and squeaked slightly when Alvin humped back into him.

"You ready?" questioned Alvin.

"Yes," answered Simon without hesitation.

Alvin nodded and laid flat on his brother's body. Simon and Alvin felt their furs pushing together and quickly pulled each other into a deep kiss. Alvin pulled out slowly and began to thrust slowly in and out. Simon gasped into his kiss with Alvin as instead of pain, pleasure flared through him. The heat exploding through his body made his own cock twitch even harder. He felt Alvin thrust back in and he gasped again in pleasure.

The feeling of Alvin filling him was incredible. He couldn't believe more people weren't gay if this was the kind of pleasure they felt. Alvin's cock felt perfect in him and after the first few seconds it hadn't hurt anymore. He could feel that Alvin was pushing in as far as he could go. His balls slapping against his skin and Simon knew it was perfect. It was like Alvin's cock had been made to fit into him perfectly.

He also couldn't ignore the pleasure of his own cock. As Alvin thrust in and out Simon's cock rubbed against his fur. Already he was leaking pre and Simon couldn't wait. Couldn't wait until he exploded all over his brothers chest.

Alvin pulled out and thrust back in. He couldn't believe how incredibly good this felt. He had never experienced such intense pleasure before. He could feel the heat flowing through his body but it was nothing compared to the pleasure he felt. Thrusting in he felt Simon's cock slide up his fur and smiled. He knew that his fur would be pleasuring Simon's cock and it made him happy. Happy that his brother would be getting a good release as well.

The kiss broke apart as both brothers needed to breath. But even as they did so Alvin increased his pace. Thrusting and and out of his brother at a suddenly jackhammer-like speed. He felt Simon's cock twitch against his chest and Simon gasped loudly.

"Oh...oh...oh.. I'm COMMING!" exclaimed Simon loudly.

Alvin continued to thrust as he felt Simon's cock twitch. Simon's cock exploded, great thick streams of sticky white semen flowing from it. Alvin felt it splatter against his fur but he had no time to enjoy it. Simon's buttocks clenched tightly as he ejaculated and the new tightness drove Alvin over the edge. His cock twitched violently and he gasped loudly as well.

"OH GOD! ME TOO!" screamed Alvin.

Alvin burst into his brother's butt, his cock twitching. Thick streams of hot semen flooded his brother's ass. Simon howled in pleasure as he felt Alvin's semen fill him. He had never felt something so incredible and it felt better than anything else. Alvin collapsed onto Simon the last of his little strength leaving him. His sticky chest fur pressed against Simon but neither of them cared.

Both of them breathed heavily and cuddled into each other's arms. Finally they were one and it felt perfect. Neither of them said anything as they cuddled closer together, Alvin's cock sliding out as it softened. Semen flowed from Simon's furry butt and mixed with his fur and spread out onto the bed. But still neither of them moved.

They were together, and it was too wonderful to break...

= = = = = Mature Scene Ended = = = = =

Simon yawned loudly with Alvin's arms pulling him closer. Closing his eyes he unleashed his energy and shielded the room as strong as he could. No one would be able to get up here leaving him and his brother in peace. Soon sleep claimed them both and together they passed out, snoring quietly on the old broken mattress.

Dave's eye twitched and he looked up towards the attic. Next time his sons decided to have sex, like they had obviously just done, he would get them to created a sound barrier so he wouldn't have to hear it. He didn't mind them being together but for heavens sake! They were his sons and that was not something he wanted to hear them doing.

Dave turned and headed towards his bedroom. The day was almost gone and he needed to get some sleep. As he walked past the window he saw a bright flash of black energy and smiled. It looked like there would be one more for the Seville household for a while.

That sounded just fine to him...

A/N: So the second part of the story comes to an end. Aaron has returned, the Chipettes had become part of the family, Dave is better and Simon and Alvin have finally been given the time to show their love for each other. But what horrors still await them. What will he do to try and destroy them next.
