Previously on GeneXXX...
Some time after events with the GeneXXX Wave, some began to submit to the natural urges and engage in sexual activity again, but only a bit. Soon, a sinister force known as the Covenant of Despair emerged. Here is another of the secret encounters that occurred during the struggles with that sinister group. (This time, yaoi free!)


Kosmo had gone to Angel Island, and found his way to a crossroads in the mountainous region of the island. There, he discovered Fera, Zeke, and Vortex facing off against Dr. Nammad, Agent 64, and a number of GUN robots! "Looks like Carrie was right." he mused as he approached Fera. "Kosmo! Good timing!" Fera said, focusing her attention on Dr. Nammad. "You're hopelessly outmatched, humans! Lay down your arms!" she warned. "What should we do, doc?" Agent 64 asked with concern. Nammad seemed deep in thought. "I don't, uh, really want to waste perfectly good uh, ammunition so, uh, quickly..." he muttered. Just then, Silver jumped down from a ledge on a nearby cliff, landing between GUN and Despair! "Stop! I won't let you get away, Covenant of Despair!" he shouted. Zeke groaned upon seeing Silver, but otherwise kept his mouth shut. Fera glanced at Kosmo. "Take care of him." she ordered. Kosmo was hesitant, but he called out to Silver. "Hey, you!" Silver stepped towards Kosmo and frowned. "Not now! Can't you see I'm busy here!" he said. Kosmo was about to say something in response, when Rainbow came up behind him! "Viola!! I found you! Now..." As Kosmo turned around, Rainbow stopped short. "Oh, wait, you're not Viola... EEEEK!! Three!!" she screeched! "Owww!! My ears!!" Kosmo growled. Dr. Nammad was watching this and looked bored. "Maybe we should, uh, retreat during this diversion." he muttered. "Kosssmo issss taking too long! Let'sss do ssssomething!" Vortex hissed. Fera rolled her eyes and jumped at Silver, knocking him aside with a darkness-charged kick! He was surprised, and tumbled into the nearby cliff wall! Meanwhile, Kosmo was herding Rainbow away from Despair a bit. "Go away!! Don't eat me! I didn't mean to bother you, mister freak!" Rainbow stammered. "SHHH! It's dangerous here." Kosmo whispered, ignoring anything she was saying. "...huh???" Rainbow gasped. "Oh, all right! Get that, uh, Beetle up here! I'll show them how I, uh, modified it." Nammad said. At that moment, things were about to get even dicier, as Sonic and company arrived!

"Huh? Wha? Hey, it's crowded up here!" Sonic observed. "Oh. Uh... It's, uh, Sonic the hedgehog. Just like Col. Gunner, uh, said." Nammad mumbled. "Hold that thought!" Sonic said quickly, dashing straight for Kosmo! "KOSMO!!! What are you scheming!?" he shouted. "Are you... with the Covenant of Despair?" Tails asked. Silver stood up shakily and looked at Sonic in shock. "Guys! You're ignoring the real threat!" he yelled. Fera noticed Professor Pickle with Sonic's group and glared at him. "Sonic... You brought a human here. You're against us!" she snarled. Kosmo gulped. "This isn't going to end well at this rate." he muttered, morphing into gargoyle form quickly and lifting Rainbow into his arms. "Hey, huh?!" she gasped. "All right, flying out! Let's go before they make a mess!" Kosmo said, taking to the sky! "Wait!! Three, lemme go! Take me back!! I gotta find my siiiiister!!!" Rainbow protested.

There was a rockslide behind them, a result of some blasting that Kosmo had hoped to get them away from. He landed them on a rocky ledge so they could catch their breath. Rainbow watched him in fear, unsure what was in store for her. "Are you okay?" he asked. Kosmo was still reeling from seeing Katie get shot, and he had no desire to witness something like that again. But Rainbow only remembered him as the monster who tried to kill everybody before, and she started hitting his chest frantically. "Lemme go, lemme go!! Don't eat me or hurt me or...!" she shouted in panic. Her assault annoyed Kosmo more than anything else. "Please...cut it out!!" he said, shoving her off him, causing her to fall backward and land on her behind. "Ooof! Ah... I see... You brought me to this out of the way cliff... So you could... SEX me!" she gasped. Since the GeneXXX wave incident, Rainbow had taken a negative view of sex, having vague recollections of being raped. Now she only ever did it when she was in a very good mood, and only with Punchy. Kosmo, meanwhile, had very little experience in this matter. With his morphing skills, he was of course able to satisfy his curiosity by posing as people's lovers, though this often went south when they asked him to remove his sunglasses. Still, since Rainbow brought it up, Kosmo wondered if maybe he deserved a little reward for taking her out of harm's way. He looked down at her darkly. "Well, what are you waiting for, then? Clothes off, please..." he said, trying not to laugh. This was the first time he'd said something nasty without being sincere. However, Rainbow thought he WAS sincere. "Waaa! Whoa! Whatever you say!! D-don't hurt meee!!" she yelped, frantically going to work pulling off her clothing in front of him! Kosmo stared in surprise, watching as her yellow-furred body was bared on the cliff before his eyes! Her nice round breasts and lovely pussy was his for the taking! For once, he had an opportunity to have sex without a disguise. So, he morphed a little something between his legs, which was actually a big something. "Get ready, girl, for a taste of morph cock!" he grinned.

While Rainbow sat on the cliff, she suddenly found Kosmo's dick shoved in her face! "Go on... Taste it!" he ordered. Rainbow gulped. "Gee, Three... But I just ate..." she mumbled. Just a look at his glowing yellow eyes made her shiver in fear, though, and she nodded obligingly. "O-okay! Sure, sounds...tasty..." she stammered, giving his purple rod a few nervous licks. Kosmo let out a soft sigh as her tongue carressed his cock, and he stroked her head encouragingly to ease her nervousness a bit. They couldn't hang around here all day, though, so pretty soon Kosmo pulled away and pinned Rainbow to the ground! "Eeeek!! Wh-what'd I do??" she gasped. Kosmo lifted her chin gently so she looked him in the eye. "Oh, you did fine... But I'm in a slight hurry..." he said, diving his thick morph cock into her pussy in the next instant! Rainbow bit her lip, trying not to let out any noise to give him satisfaction. His dick was so thick that it was a tight fit in her passage, though, and what's more, Kosmo searched out her sweet spot fairly quickly. Once he hit it, she found herself squealing loudly, grabbing his shoulders in a fit of blind passion! Kosmo smirked, and gave her breasts a good squeeze, coaxing further moans from the colorful echidna below him. "Aaaahhh... You like that, girl? Not so full of protest now..." he moaned, ramming her sweet spot yet again and making her cry out from the intense pleasure! "Oooohh!! Th-three!! Wh...Why does this feel so good?? I... I..." she panted, giving up her words in favor of kissing her captor lustfully! Kosmo's tongue met hers and lapped against it eagerly, excitedly. Another thrust to her sweet spot pushed Rainbow over the edge, splashing Kosmo's crotch with cum as she let out a long, loud gasp into his mouth! Kosmo pulled away from their kiss, and felt ready to finish this. "All right, girl... Time to sow my seed now..." he grinned, slamming his cock deeper into her depths, fast and hard! Rainbow heard his words and widened her eyes. "Do...what now??" she gasped. However, it was too late, and with a dramatic cry from both of them, Kosmo's seed blasted deep inside her! They laid on the cliff, with Rainbow held tight in Kosmo's arms, and he noticed a cave not far from them. "...I know where to go next... Let's keep you safe... In case you are carrying my young." he said softly. Rainbow shivered a bit. "Your...young?!" she gasped.

Kosmo descended into the cave to escape the dangers above. However, now they found themselves in a cavern of bubbling lava and weak rock walls and floors. They were in Lava Reef Zone. Rainbow backed away a bit once Kosmo put her down. "Well, ha ha... This has been fun, Three, but I better get looking for my sister, now..." she stammered. "Your sister? Why would she be here? ...Is she with the Covenant of Despair?" Kosmo asked. Rainbow stopped backing away and stared at him. "Huh? You care??" she murmured.
