Hello, everyone, this is IndigoWerewolf with my newest story, The Rules of the Digital World. This is a yaoi story, which I haven't done before, but I hope you enjoy it regardless. If you don't like yaoi, please look elsewhere. I do not own Digimon and all characters portrayed in a sexual manner are 18+, let's read!

In a forested area of the Digital World, a Gabumon was drinking water at a lake when he heard a rustling from the bushes behind him. He turned around. "Who's there? Show yourself!" he said.

A Kotemon stepped out from the shrubbery. "Hello, there," he said.

Gabumon relaxed. "Oh. Hello. Sorry, did you want a drink, too?"

Kotemon drew his bamboo sword. "I'm not looking for water. I'm looking for an opponent. And I think I just found one!"

Gabumon raised his fists. "I'd rather not fight. But if you insist, I guess I have no choice."

Kotemon rushed at Gabumon. His sword blazed. "Flaming Bamboo!"

Gabumon blocked the sword with his forearm. Blue flames curled in his mouth. "Blue Blaster!"

Kotemon dodged to the side. He kicked at Gabumon's stomach with his sharp clawed feet. Gabumon knocked him back with a strong push to his armored chest.

The two Digimon fought and exchanged moves until they were both panting and exhausted. Kotemon knocked Gabumon to the ground with one last swing of his sword.

Gabumon groaned. "Fine. It looks like you win. Just load my data already," he said.

Kotemon sheathed his sword on his back. "Oh, I'm not interested in your data. I have something else in mind," he said. He undid a section of the armor on his lower half, exposing his thick six-inch gray cock.

Gabumon sat up, groaning. "Seriously?"

Kotemon went up to him. "I beat you in combat, so now I get to do anything I like with you. If that means I want to use your body, then that's what I'll do." He rolled Gabumon onto his hands and knees.

Gabumon grunted. "I know the rules. Go ahead and use me."

Kotemon kneeled behind him. "Gladly." He lifted Gabumon's tail, humming at the sight of his tight puckered hole. "Nice and tight. Lube would probably be a good idea, though." He leapt into a nearby tree and picked a transparent fruit. He returned to his original position and crushed the fruit. Slick, neutral-smelling gel covered his hand.

Gabumon tensed as Kotemon worked one slick finger inside his tailhole. Kotemon fingered his hole, lubricating him thoroughly. Gabumon took deep breaths. The sheath between his legs bulged and his five-and-a-half inch cock emerged from it.

Kotemon said, "Looks like you're enjoying yourself." He worked a second lubricated finger inside Gabumon's hole, making him groan.

Gabumon panted. "Might as well," he said. He cried out when Kotemon added a third finger.

Gabumon's cock was hard and leaking pre when Kotemon withdrew his fingers. "That should do it." Kotemon stood up and used the rest of the lubricant to slicken his cock. He grabbed Gabumon's hips and lined himself up with his tailhole. "Get ready."

Gabumon gasped when Kotemon penetrated him. The head of his cock popped into the Beast Digimon. Kotemon groaned. "I was right about you being tight." He slowly pushed further in.

Gabumon clenched his jaw as Kotemon slid his cock into his anus. He did his best to relax and not tighten himself. His cock leaked precum. Kotemon sighed when he fully sheathed himself in Gabumon's ass. He held himself inside for a few seconds.

Kotemon pulled out until only the head was inside Gabumon before thrusting in again. Gabumon grunted every time their hips met. His tailhole gripped and squeezed around Kotemon's cock every time he pulled out. He took deep breaths as his ass was used by the other Rookie Digimon.

Kotemon thrust eagerly into the Beast Digimon. His hands gripped his hips. He pumped into Gabumon vigorously. His shaft throbbed inside of him. Their testes touched with every thrust. Kotemon fucked his prize as Gabumon's cock bounced below him.

Gabumon groaned. "I have to hand it to you… You're better at this than I thought you would be," he said.

Kotemon was panting. "You're not my first conquest," he said.

He angled himself to rub against Gabumon's prostate. The Beast bucked his hips back and shouted out. His shaft was twitching and leaking precum. His ass was squeezing tightly around Kotemon's cock. The Beast Digimon was groaning and trembling as he was fucked.

Kotemon thrust into Gabumon vigorously. He held the other Rookie's hips as he used his tailhole for his pleasure. His cock was throbbing inside of him. Gabumon's rectum was tight and hot, and wet from the lubricant he had used. He could feel pleasure building more and more the longer he kept fucking.

Gabumon panted in pleasure. Despite the situation he was in, he couldn't help the feelings rising in his body. His prostate was throbbing with every thrust and rub against it. He could barely stay upright. The ground below him was spotted with his pre. His cock was jumping as he grew closer and closer to cumming. He grit his teeth when he felt his testes tighten. "I'm cumming! I-I'm going to cum!" he said.

The Beast Digimon shouted out as he shot his cum on the ground. He shuddered through his orgasm and the pleasure filling his body. Kotemon groaned and gave a few more thrusts into his ass. "There. We. Go!" he said. He bottomed out inside of Gabumon. His hands gripped his hips tightly as he came inside of him. He filled the other Rookie Digimon with his hot spunk and painted his insides white.

The two Digimon trembled in orgasm for a second before Gabumon's cock shot one last strand of cum. He relaxed and went limp in Kotemon's grip as the Reptile Digimon's own orgasm ended. He sighed and pulled out of Gabumon's anus, watching it gape and leak. "Now that's a sight," he said.

Gabumon panted. "Okay, you got what you wanted," he said.

Kotemon shook his head. "Not quite. I'm not satisfied yet." He gestured to his still-hard cock.

"Seriously?"

"Seriously." Kotemon flipped Gabumon onto his back. "I think I'm in the mood to take it a little."

Gabumon tensed when Kotemon grabbed his softening shaft. He stroked the Beast Digimon's flagging cock slowly, making his breath deepen. Kotemon stroked him until he was fully hard again. He hummed. He got onto his knees and leaned in. Gabumon gasped when he took his cock into his mouth through one of the gasps in his mask.

Kotemon bobbed his head on Gabumon's penis. The Beast Digimon clenched his hand and grit his teeth as he sucked and hummed around him. Although he couldn't see it due to his helmet, he could feel his hot warm mouth enveloping his cock.

Kotemon pulled away when Gabumon was slick and wet. He quickly got another clear fruit from the same tree and turned away from Gabumon before undoing the rest of the armor on his lower half. He bent over to show his tight tailhole.

Gabumon watched as the Reptile Digimon fingered himself with the fruit's lubricant. He was taking deep breaths as he pumped one, then two, then three fingers into his ass, scissoring them and preparing for the Beast's cock.

When Kotemon was fully prepared, he turned back to face Gabumon and straddled his waist. Gabumon's cock twitched when the head touched Kotemon's hole. "Ready?" Kotemon said.

Before Gabumon could respond, he dropped down. Gabumon's breath caught and he bucked up into the other Rookie. Kotemon hummed and stayed still for a second, Gabumon's cock hilted inside of him, before rising up and dropping back down.

Kotemon rode Gabumon, slowly at first but gradually increasing his pace. With every movement of his hips, he took his cock into his tailhole. He fucked himself with the other Rookie, using him like a dildo as he gasped and moaned.

Gabumon was taking deep breaths. His cock was surrounded by tightness, wetness, and heat. If this was what Kotemon had felt when he was using his ass, then he could see why he had gone looking for it. He didn't want it to end. He was tempted to try to turn the tables on Kotemon, pin him down, and fuck him until neither of them could walk. After he was done riding him, of course.

Kotemon was panting. Gabumon's cock wasn't the first he had ever had inside of him, and it wasn't the biggest, but it was nonetheless satisfying. His tailhole was flexing as he milked him as much as he could. He rode Gabumon vigorously, enjoying the feeling of his cock pounding into him with every drop of his hips. His penis bounced with every movement he made. His prostate throbbed, sending waves of pleasure through his body whenever Gabumon's shaft touched it.

Gabumon gasped. His hips bucked up and a drop of pre-cum beaded from his cockhead. "I'm going to cum!" he said.

Kotemon squeezed his anal muscles tightly. "Cum inside me! I want your cum inside my ass," he said.

Gabumon's eyes squeezed shut. His hands gripped the dirt beneath him. His cock twitched and his testes tightened. He came inside of Kotemon, shooting his hot semen deep into his rectum. Kotemon gasped. He slammed his hips down a few more times before going still. His cock jumped as he reached his own orgasm. His cum shot across Gabumon's face, a few strands landing in his mouth.

The two Rookie Digimon came for a moment, Gabumon inside of Kotemon and Kotemon on Gabumon. Soon, they both relaxed. Kotemon lifted up and let Gabumon's cock slip out of his tailhole. He sighed and stepped away to pick up his bamboo sword.

Gabumon lifted his head. His penis twitched when he saw Kotemon bend over and show his gaping, leaking tailhole. "So now you're leaving?" he said.

Kotemon straightened up and turned back to him. "What were you expecting? A cuddle session?" he said. He redid the armor on his lower half and put his sword on his back.

Gabumon rolled over onto his front shakily. "You do realize, that when I'm stronger, I'm going to find you and do the same thing to you that you just did to me."

Kotemon chuckled. "I look forward to it." He walked away, feeling cum drip down his leg.

And that's the end of the story? Chapter? I might continue this if it's well-received. If you liked it, let me know. If you didn't, why did you read it all the way through? IndigoWerewolf out!
