This universe was once known as GeneX Heat. It was quite similar to the universe formerly known as GeneX Prime (any name change there will be addressed in another story). The difference between Heat and Prime, was that the denizens of Heat were consumed with lust. Therefore, when the treat of the Lost Ones came to their world...they were too distracted, and they ended up destroyed. Their world started to crumble with all the souls devoured from it. However, heroes from GeneX Prime defeated the Lost Ones and restored those souls. But the trauma of their world's destruction was too great to bear. Fortunately, a certain Demigod fox had regained his powers to an extent, and using a massive amount of those powers, he repaired the crumbling world, and gave the inhabitants something of a "soft reset." Their memories were mingled with the memories of GeneX Prime. Some events were forgotten. Some events that happened in Prime, were now recalled by this new, reformed dimension. This dimension is now simply known as NexxxGen. It continues on with the same basic actions as the Prime dimension, and also continues its insatiable lust. Recently, a group of heroes from this dimension have settled in a small coastal town on an isolated island. The town has been named "NexGen Village." And with the arrival of these heroes, seeking a nice vacation from their previous adventures, our new tales of lewdness can at last begin...

Being so close to the beach, the inhabitants of NexGen Village were enjoying some fun in the sun on this day, so soon after they'd started settling in. Tails and Copter, the twin tails foxes, were playfully splashing one another in the ocean, while Silver the hedgehog and Marine the raccoon were further out, catching waves on their surfboards. Gemini and Libra, the fennec twins, were lounging on beach chairs, each wearing rather revealing bikinis. Violet the echidna stood over Gemini, blocking her sunlight. She was wearing a one-piece swimsuit. "So, Gemini... Totally forget that deal we had? That neither of us were gonna date Copter if he mistreated either of us?" she asked, recalling the nature of her own breakup with the black kitsune. Gemini glanced at her with a soft chuckle. "Don't you think he's earned forgiveness? He beat you up in a FIGHTING tournament, and maybe he went overboard there, but he's helped save the whole world since then..." she stated. "Besides..." Libra added, sitting up, "If Gemini doesn't sleep with Copter, then Chopper will never be born!" she said with a playful smirk. Gemini shoved her off her chair. "Yes, thanks for that, sis..." she grumbled. Violet folded her arms with a bit of a sad expression. "Yeah, you had a kid show up from the future... I didn't. I guess that means...I'm the big loser in the end, huh?" she murmured, turning to walk away. Libra climbed back into the seat. "Girl needs to get laid, huh? ... I kinda know how she feels. Not fun just watchin' you two and knowing I got nobody..." she murmured. Gemini glanced at her sister. "Well... There's some single guys here..." she said. Libra scoffed. "Oh, yeah. Vortex and Zipp. Real winners there..." she sighed.

Copter happened to notice Violet speaking to Gemini, and returned to the shore, drying off in the sun for a bit. He turned to Tails nearby. "Musta been nice, hm? Having a harem for a bit. Who all did you have... Cream, Blaze... Cosmo?" he asked. Tails had to blush. There weren't a lot of girls they knew that he hadn't banged at this point. "I'm kinda trying to be faithful to Cream now..." he said. Copter nodded. "Guess you ought to milk that pretend wedding for all it's worth... No idea why ya didn't just do the real thing. How old you wanna be, forty?" he asked. NexxxGen Dimension's inhabitants may have been a bit older than their Prime counterparts. Perhaps that influenced their sex drives. Tails cleared his throat to get off the topic. "Ahh, well, Copter, if you're so jealous of the harem, why don't you... get one?" he suggested. It was Copter's turn to blush. "Seriously? Who, Vortex and Zipp? Real winners there..." he murmured. Tails groaned. "No, dummy. There's a bunch of girls here without boyfriends. Just ask them... if you want." he suggested. Copter glanced out at Gemini relaxing in her chair. "I'd need Gem on board. Probly gotta be something in it for her. Would you...?" he murmured, glancing at Tails. The brighter-furred fox stepped back anxiously. "Say, where even is Cream right now? Ahh, talk to ya later, Copter!" he said hastily, rushing off. Copter chuckled softly. He was somewhat kidding...but he couldn't deny, the thought of a three-way with Gemini and Tails wasn't lacking in fun. Nor was the thought of his very own harem...

Later on, Copter returned to the small hut he was sharing with Gemini and Libra. Both sisters returned with him, and it gave him a bit of a dilemma...because he was horny now, but for some reason, Libra was staying in the same hut as him and his girlfriend. Copter sat himself on the bed and sighed. "Y'know, Libra... I'm sure there's room for us to build you your own place..." he said to her. She gave a stretch, which showed off her lovely figure, and sighed calmly. "Why would I wanna leave?" she questioned. Copter glanced at the chair in the corner of the bedroom. "Then, uh... You could have your own bed..." he murmured, thinking about how she'd been sleeping in the chair. Gemini sat down on the bed next to Copter. "Well, she could also just join us in the bed..." she told him. Copter gulped. That would possibly be awkward...or possibly be amazing. "Gemini... Don't you know how hard it'd be for a guy like me to sleep in the same bed with my girlfriend AND her twin sister?" he asked, trying to put it delicately. Libra and Gemini exchanged glances, and nodded to one another, starting to smirk to themselves. "Well, you know... some twins really do share everything." Libra stated as Gemini placed an arm around Copter. "And I mean, I did share you with Violet for a time before..." she pointed out. Copter's face went bright red. "Y-you're s-sisters, though..." he stammered. Libra held her breasts through her bikini top, teasing Copter. "You're saying you don't want to fuck us both?" she asked bluntly. The tent in Copter's pants was undeniable at this point. "T-to be clear... Would you both be... my girls?" he asked. Gemini kissed his cheek and looked to Libra, who blushed and nodded. "Yes, Copter... After all this time together... I want to be yours..." she cooed.

Gemini stood up next to Libra, and the twin sisters began to shed their bikinis just for the black fox. They each turned, bending over and showing their asses, Gemini's all pure white-furred, and Libra's light blue both being bared slowly as they slid down their bikini bottoms. Copter watched their tails wag, realizing that both sisters genuinely wanted this. "Oh, man... Yeah, I'm finally on vacation..." he sighed, watching as the sisters turned his way, hands running up their thighs and over their bellies. It was like they rehearsed this, their movements were so in synch. Gemini's hands ran up the light blue fur of her belly, while Libra did the same with her gray belly, each rubbing their covered breasts for a moment. "You and I, we're destined..." Gemini cooed, "Our son proved that..." she added. Libra purred softly as she fondled her breasts. "But all is uncertain with me... Mmm, will I carry your child, too? Do you want me to?" she whispered. Copter's eyes widened as he watched them unfasten their bras. "...Oh, yes..." he huffed, not really thinking about it. He just wanted to fuck her. Their bras fell, unveiling their breathtaking busts, but only for a moment, as the naughty sisters turned toward one another, embracing each other. "Okay, Copter... But I expect you to impregnate us both within the same month... I want our babies to be like twins, too..." Gemini cooed, kissing Libra as their breasts pressed together, the sisters driving Copter wild as they made out in front of him! Copter tugged off his pants, his hardon swinging free as Libra broke the kiss, nuzzling Gemini as she admired Copter's shaft. "Don't give us your baby too soon, either... I wanna experience your love for a good long while..." she said, licking her lips.

Before Copter could stand up, both sisters had knelt down between his legs. Gemini took hold of the base of his cock, and tilted it toward Libra as if offering it to her. Libra gladly gave his tip a kiss, and then licked it. "Mmm, been a while..." she cooed. That's right, Copter recalled, he'd actually fucked both sisters together once before, shortly after the fall of the Zodiac Council. He'd honestly expected that to be a one-off, but here they were, both sisters now taking turns licking his hard foxhood. Gemini lowered herself a bit to lick and suck his black balls while Libra polished his rod with her tongue. "Ahh, you've even bigger than Tails..." Libra purred, just to flatter him, but Copter knew full well he and Tails were roughly the same size. Gemini moved back up to his shaft, her tongue meeting Libra's before drawing her sister into another naughty kiss. Copter grunted softly, his dick twitching with need. "Y-you girls... Ahh, I'm gonna fill ya both to the brim!" he growled. Gemini broke the kiss, glancing at Copter's cock and swirling her tongue over his tip. "You promise? Of course, if you wimp out on us, I could always fix ya with magic..." she smirked. As if an Experiment would "wimp out." Copter pet both sisters and smirked. "Alright... Libby, get up here. I wanna welcome you to our little family properly." he winked. Technically Gemini and Libra were the ones that were related, but no one cared to split hairs about it. Libra stood over Copter, her lovely breasts finally hanging in full view for long enough to be admired. "Make sure you give my sis a good show, then, big boy..." she smirked.

Libra climbed onto the bed, laying on her side, and Copter laid himself behind her, grabbing her upper leg and lifting it a bit to enable himself to get into position, soon slipping his cock into her pussy, all while Gemini watched! Once he was inserted, he wrapped his arms around her waist, kissed her shoulder, and started to thrust! "Ohh!! Mmm! That's it... got a good view, Gem? ...aaahh! Libby f-feels... like home..." Copter grunted, noting how similar her pussy felt to her sister's. And he would know, Copter had fucked Gemini every chance they got since their vacation began, every time they could get away from Libra long enough. But now, it felt great knowing...they'd no longer have to wait for such an opening. Libra gasped as Copter held her and plunged his shaft deep inside her, holding nothing back! "Ooohhh, ahh! H-how I've longed f-for this..." she purred, her tail coiling around Copter's body as she happily accepted his cock, even as her sister could witness every thrust so clearly! Continuing to hold her, Copter slid his hands up, grabbing hold of her breasts while roughly humping into her deep depths! "Well, now you're all mine! Ahh... Whatcha think of that, Gem?" he huffed, looking at her with a smirk. Gemini was actually jerking her magic wand inside her pussy, using it like a dildo as she watched. "Sh-shit, why is this s-so hot?" she panted, her cheeks flushed pink. Libra lifted back her head and moaned as Copter groped her breasts, and his dick pounded at her weak spot at the same time! "Y-yes, I-I'm yours! Ahh...p-please, f-fill me up, C-copter!" she cried. Copter gripped her leg again, stabilizing his thrusts, pounding into her fast and hard...until finally he gave her what she wanted! His cum shot deep inside her, filling the fennec with warmth, and she cried out in joyful lust at the feeling. "Ahhh... Th-thank you... m-my boyfriend..." she sighed.

Now, it was Gemini's turn. She laid herself down on the bed a few inches beside her sister, and almost immediately, Copter was on top of her, his lips latching onto hers in a passionate kiss! Libra was hot, but it was Gemini he loved, and he made sure she knew it as he held her, deepening that kiss, and blissfully purring even without touching her with his dick. Gemini raised her legs up as the kiss broke. "I know what was said... But I want you to take me like you're trying to get me pregnant..." she whispered. There was a part of her that was thrilled by the possibility. It was really giving the finger to the old purity rules she had to go by when studying magic. Copter took hold of her raised legs, and keeping a hold on them, gave a deep, forceful thrust of his cock into her waiting pussy! It always felt incredible inside her, in a way that no other girl could quite compare for him. "Oh, I'll getcha pregnant... It's our destiny!" he smirked as he started to thrust, making Gemini cry out in blissful joy, once more feeling his length against her walls! That destiny line would be incredibly cheesy and embarrass Copter if it wasn't true, but they knew the future. One day, he would indeed plant his seed successfully. Holding her legs, Copter drilled his shaft deeply inside his lover, watching her come undone under him as she often did, any semblance of that good girl facade melting away as she moaned in lust. "M-more! Yes... d-deeper! Mmm... Th-this...is real magic!" she panted, clutching the bed sheets under her as her body writhed, uncertain what to do with herself as that dick overwhelmed her senses! Copter slung her legs around himself and caught her lips in another kiss, massaging her breasts in his hands as he gave a few more quick, deep thrusts. Their cries were muffled by the kiss as he came, flooding her pussy with his essence! One day... this act would create life.

The sisters took turns on Copter's cock for a couple hours, and the black fox eagerly gave them all he had to give. By nightfall, he was resting on the bed, his head finally on the pillow. A sister was wrapped in each of his tails as they dozed beside him, worn out. Copter was still quite awake, though. He was thinking about the idea of a harem. If Gemini and Libra didn't mind sharing him like this...perhaps he could get Violet back, too. He licked his lips at the thought. His sex with Violet had always been incredibly hot. Gemini stirred next to him, her hand resting on his chest as she nuzzled him. "I love you, Copter..." she cooed softly. He nuzzled her back and purred. "Love you more, Gem... My Gem..." he whispered. That was his one and only concern. Would building a harem hurt his relationship with Gemini? He'd been through some relationships, and he knew Gemini felt different. Real. As horny as he was, he didn't want to lose her. His tail coiled around her tighter, and he took a breath. "If I get Libra... You get another guy." he told her. This felt fair. Every girl added to his harem could mean another guy Gemini could fuck too. She mumbled something tiredly, but Copter couldn't understand it. Maybe she was too sleepy to hear him. So, he thought for himself. "I get Libra and Violet... Maybe Gem gets... Tails and uhh... Hmm..." This line of thought admittedly made him uncomfortable. So, he decided to sleep on it all. They were on an island with several other Mobians. Certainly, the chance to decide about these naughty hookups would present itself...
