Chapter 1

On a sunny spring day, high up in the mountains, in a cavern full of stalactites, Team Hooligan was up to no good again.

Not long ago, they had gotten a signal on their equipment, sporting of some incredible power in this cavern. Naturally, they thought it was an emerald, whether Sol or Chaos, it didn't matter to them. All they cared about was the money they would get from selling such a precious jewel.

"The signal says it's right here, Nack." Bark said to the weasel. "But there's nothing here."

"Idiot, it must be in the wall." Nack rolled his eyes. "I think it's time to go mining boys. Bean? Do your stuff."

"Heheh, you got it!" The woodpecker beamed, pulling out a bomb out of thin air.

The fuse was already lit, sparking and hissing loudly. Bark and Nack moved quickly to get out of the way of Bean's bomb before he threw it at the wall, a huge explosion causing a huge crevasse in the wall.

"Yeah! Ten points!" Bean praised himself.

"Good job Bean, let's get that emerald boys."

However, before any one of them could take a step, from the hole in the wall, a portal suddenly opened up, glowing with purple-pink swirls and shining with demonic light.

The Hooligans' equipment started to go haywire, not made to handle as much power as the portal holds.

"What is that thing?!" Bean asked nervously.

"I-I don't know, Bean." Nack gulped, sweating a little as it suddenly got very hot and damp in the cavern.

"Is it just me, or is it getting hot in here?" Bark asked.

"It does feel a little warmer." Bean nodded, starting to feel a bit uncomfortable. He could feel the warmth traveling to his nether regions, slowly starting to arouse him. The thought of becoming hard for nothing made him blush. "I kinda feel uncomfortable."

"Same here." Nack agreed, rubbing his legs together as he started to have the same problem, his cock getting more harder and wetter than Bean's was. "I vote we get out of here, now."

But before the Mobians could turn to leave, something came out of the portal.

It was an imp. He was small and completely naked, a large pulsing red cock hanging between his legs. The Hooligans flush at the sight, all turning their heads away as they feel another wave of lust wash over them.

"Do not look away ashamed." The imp snickered. "I know I am beautiful. My name Zetaz."

"W-we're The Hooligans." Nack introduced, still not looking at the imp. "I'm Nack, that's Bean, and that's Bark."

"The three of you seem stressed, tell me, are you three filled with lust by any chance?"

The Mobians flinch, their faces getting darker. The imp laughs at their reaction.

"I know you are… why, the weasel already has his dick out."

Nack gasps and looks down. Sure enough, his shaft had slipped out of its sheath, the pink flesh glistening and hard with desire. Blushing with shame, he quickly covers himself with his hands, moaning softly as he accidentally rubbed it. Ashamed, he turns away from his team, his ears down and eyes closed, trying not to cry in embarrassment.

"Aw, come come now Nack, there is no need to be ashamed." The imp cooes. "After all, it's only your body reacting in a very natural way. You cannot control it."

The imp gives a toothy grin. "If you three would like a quick remedy to your hard-ons that doesn't involve intercourse or masturbation I can take you to my master. They're a bit of, an expert on corruption."

"Who is your master?" Nack asks, looking back with glistening eyes.

"Oh you'll admire them dearly. Come come, I will take you to them."

The Mobians look at each other quizzically before all hesitantly walking through the portal, curious about what they may find.

"Yes, excellent." The imp snickers as he follows them. "And so, the corruption begins."

"Sonic! I think you better come look at this!" Tails called from his workshop.

Sonic quickly ran down the stairs to his little fox brother's workshop at the sound of his call. When he reached the bottom step, he ran up to the fox, who was click-clacking away on his laptop, looking a little panicked.

"What is it, Tails?"

"Look at this." Tails moved the laptop to show the screen to the blue hedgehog. "The satellite has picked up some extremely strange and strong energy up on Mount Ilgast. The whole system is going absolutely haywire!"

"What do you suppose it could be?" Sonic asked curiously.

"I don't know. Perhaps it's an Eggman source, or a very powerful gem that we don't know about."

"That doesn't seem too impossible. After all, we knew nothing about the Phantom Ruby before we battled Infinite."

"Exactly."

"Could there possibly be another alternative?"

"Well, like the portal to the Sol Dimension, it could be a wormhole to another dimension."

"We should grab Knuckles and check it out." Sonic suggested. "With something this powerful, we don't need it falling into the wrong hands."

"Agreed."

Minutes later, Sonic, Knuckles, and Tails arrived at Mount Ilgast on the Tornado and landed on an overhang. They jumped out and began walking towards the source, the help of Tails Miles Electric showing them where to go.

"If it's a gem let me handle it." Knuckles ordered. "A gem this powerful could be highly dangerous."

"Agreed." Sonic nodded. "I don't know much about gems except for the Chaos Emeralds, so if it is a gem, that's your specialty, so I'll let you handle it."

"That's very mature, coming from you." Knuckles smirked.

"Hey, I've grown up a little over the years, alright." Sonic chuckled.

"It's this way!" Tails called as he turned a corner, his device beeping like crazy.

Sonic and Knuckles quickly followed the boy genius. The device started going crazy the closer they got to the source. Suddenly, it started spazzing out.

"It's here, right in front of us."

The three looked up and witnessed the cave, the same one that the Hooligans had found the portal. They were shocked when they discovered that they weren't the only ones there.

Shadow the hedgehog sat against the wall outside of the cave. He was panting and covered in sweat, a dark blush adoring his face. His eyes were glazed over and his legs were shaky.

Concerned, Sonic quickly ran up to the black and red hedgehog, kneeling down next to him.

"Shadow! Are you ok?"

Shadow blinked and looked up to the blue hedgehog. He took a deep breath, closing his eyes as he laid his head against the wall.

"Yes." He panted. "I'm fine. Just need to catch my breath."

"What happened?" Tails asked him.

"You don't wanna know." Shadow shook his head, not about to tell an 8 year that he just got done masturbating because of the cave.

"What are you doing here?" Knuckles asked him suspiciously.

"My senses picked up a strange energy source, so I came looking for it. The source led me to this cave." He looked up at the three. "I take it you were doing the same?"

"Yeah." Sonic nodded. "The Miles Electric led us here. What is it Shadow? Did you see it?"

"I did, and it's nothing like I've ever seen." Shadow nodded. "It's a portal, pink and swirly, with demonic light shining through it. I've seen some strange creatures coming through it."

"What strange creatures?"

"Goblins, imps, trolls, succubi. It's like a whole fantasy land over on the other side. But… it's no fantasy land I have ever heard of… the creatures seem… corrupted."

"Corrupted?" Knuckles frowned. "What do you mean? Corrupted how?"

To the surprise of the three, Shadow pressed his ears against his head and looked down, his blush getting darker.

"Corrupted by… lust." He answered hesitantly. "When I was in the cave and I saw these creatures, they kept talking about how they couldn't wait to fuck everyone and everything. One of the goblins, when she noticed me, actually tried to rape me."

"Oh gosh Shadow, that's horrible!" Sonic gasped, wrapping his arms around the hedgehog in comfort.

"She wasn't successful, hedgehog, I don't need your comfort." Shadow hissed as he pushed the blue hedgehog off him, though not harshly, knowing that Sonic was just worried about him. "I was able to fight her off before she could touch me."

"Then how come you look like you just got done having sex?" Knuckles asked bluntly.

"Knuckles!" Sonic hissed at the echidna.

"That's none of your business, echidna." Shadow hissed.

"I agree." Sonic nodded, but then looked at Shadow, a fire of anger in his eyes. "But Shadow, if that goblin laid even one finger on you…"

"She didn't, Sonic, I swear it." Shadow quickly tried to calm him down. Then he sighed. "But… if you really just have to know… she splashed me with this… lust draft or whatever it was. It… made me uncomfortable and… warm and… well… the humidity of the cave didn't really help either so… I had to find some way to… to calm myself down…"

"Oh." Sonic, Knuckles, and even Tails breathed sympathetically.

Sonic growled and shook his head. "What kind of messed up world is this?"

"It's called Mareth."

The four jumped at the new voice that spoke to them. They looked towards the source and saw an elderly human man approaching them.

"Who are you?" Tails asked him.

"I am Elder Nomur, the guardian of this cave." The man explained. "My job was to foresee it that nobody entered this cave, though it seems that on my short leave, the inevitable has happened."

"You said something about Mareth?" Sonic tilted his head curiously. "What exactly is that?"

"Beyond the portal is a demon realm known as Mareth. The land and air itself is filled with corruption, which seeps into the minds of those who inhabit it and fills them with undying lust and libido. The creatures on the other side would do anything to gain their sickly pleasures, even force themselves on others." The elder's eyes traveled to Shadow, who instantly looked down at his gaze. " For a thousand years, the portal has been covered, hidden behind a wall of rock. But now, that wall has been destroyed, and the portal glows brightly as the creatures of Mareth come through, looking for fresh virgins and sluts."

"How awful." Sonic shook his head. "This world needs to be stopped. It needs to be destroyed. A world like that should never exist."

"There is a prophecy." Elder Nomur continued.

The four Mobians looked at him, urging him to continue.

"When the wall breaks and the portal glows, a champion of blue steps up, with speed and agility, to break the curse of the land of corruption, once and for all."

"A champion of… blue?" Sonic gulped. "With speed and agility?"

"Sonic… as much as I hate to say this… I think this so called prophecy is speaking of you." Shadow said to him.

"I think you might be right." Sonic nodded nervously. "But if I'm that champion, what am I supposed to do?"

"If you are the champion, you must enter the portal into the land of corruption." The man explained. "Find the master in control of this corruption, and destroy him and the world in its wake. What you speak is true, young lad. A world so corrupted should not exist."

"So… it's up to me." Sonic gulped.

"We can't possibly be sure about that." Tails tried to reason in a panic. "It could be talking about another Mobian."

"But what Mobian could that be, Tails?" Sonic asked him. "What other Mobians is blue and has speed and agility?"

"But it's dangerous!"

"I've been through worse, Tails… you know this." Sonic sighed and looked at the elder. "If this prophecy is speaking of me, then I will do whatever it takes to destroy this corrupted world."

The elder nodded. "Then so be it. Go now. You must train your body and mind to handle the corruption of Mareth. Do not come back until you are ready."

Sonic nodded as he stood up, helping Shadow up to his feet as well.

"Can we go with him?" Shadow asked curiously.

"I'm afraid not." Elder Nomur shook his head. "The corruption of the land is too risky, you may end up fucking each other."

The four Mobians cringed, not wanting to think about that happening.

"And another thing. Once you enter the portal, the chances are you may not come back out."

The four looked at each other, now actually worried for Sonic's life. The blue hedgehog sighed and looked at the man.

"If that is the price I must pay, then so be it." He frowned and turned away, walking back to the Tornado. "Come on guys. There is training that I must endure through so I may be able to control myself. I will not allow Mareth to corrupt me."
