Previously on Sonic GeneXXX...
Several of the guys had bet on who could successfully seduce Sonic and make him their boyfriend. After all the others had made their attempt, it was Shadow's turn. Sonic's attraction to Shadow was so great, it caused a reaction with the "safe-sex vaccine" Bucky had given him earlier in the year, turning him female! After figuring out Bucky was behind this (and making good use of Sonic's female body), Sonic turned back into a male and the hedgehogs decided they should confront the rat.
Tommy wanted to talk to his brother Razor about having had sex with Katie earlier in the year, but Razor was drunk. Instead, Kosmo offered to help him "practice" sex, as that's what the young porcupine really wanted deep down.
...And now, the conclusion...for the Yaoi side of things.


Razor was frantic when he sobered up and found Tommy not at home. He vaguely recalled running into his brother in Troblusk City, but the details were a blur. "He didn't come home last night!!" he said to Ridley, panicking, "What's happened to him?! Damn, I won't forgive myself if he's hurt!" he shouted, ransacking his house for clues. Ridley watched calmly and cleared his throat to try to get Razor's attention. "I... don't think your brother's in the couch cushions. Why don't we treat this like any other missing person case. What would you do, then?" he asked. Razor sighed. "I... I don't know! I'm not really a detective..." he grumbled, "...I guess I'd call someone better qualified to work the case. Good thinking, hun." he said, giving Ridley a quick kiss before rushing off to get help.


Tommy had stayed with Kosmo after their evening of sex, even going some extra rounds with the horny morph, who took multiple forms to keep things interesting. Now, however, they were resting in Kosmo's huge bed with the pink sheets. As they laid in each others' arms, it wasn't long before their calm was interrupted. The door was soon kicked open, followed by a certain growling gargoyle stepping inside! "Grrrr!! Let the kid go!!" was the first thing Guard said. Kosmo and Tommy sat up with a start, but Kosmo was quick to compose himself. "Off you go, short stuff... Looks like you've been out past curfew." he said. Tommy climbed off the bed and slowly headed for the door. "D-don't hurt him... He didn't do anything. He's my friend." the young porcupine said before heading on his way. Guard grunted and kept his attention on Kosmo. "So... You're abducting little kids now, are you?" he growled. Kosmo stood up and crossed his arms. "I didn't abduct anyone... And I know for a fact he's not 'little'..." he smirked. Guard growled softly. "His brother asked me to track him down... and you know Gunner's asked me to track YOU down..." he said bluntly. "And now you've done both. Bravo." Kosmo replied, "Is that not enough for you? Feel the need to 'punish' me for some perceived wrongdoing?" he asked smugly. Snarling, Guard leapt at Kosmo and tackled him to the bed, pinning him down! "Grrrr... Yes!!" he shouted. Kosmo stared up at him and smiled awkwardly. "I could go female like I did for the runt... Or would you rather punish me as is?" he flirted. Guard let out a confused grunt, blushing a little. However, he quickly came to accept this notion. "...Grr... If I see you glow even a little, I'm bringing you in..." he warned. "Ooooh, so feisty... dominate me, tiger..." Kosmo murred.

Guard began by rubbing at the morph's crotch, but got no reaction. "Uh, if you want anything there, I DO have to glow that spot for a sec... The ability to be both comes with the cost of owning neither, so to speak." Kosmo said, blushing. Guard sighed and nodded. "Rrrr... Without it, I don't think mine will want to come out to play..." he replied with a blush of his own. So, Kosmo's crotch glowed briefly, adding a plump rod and some proportionate balls to his anatomy. Guard felt it slide into his grip as it appeared, and smirked as he began to stroke it, his own cock slowly emerging as he enjoyed fondling the morph's equipment. "You can be any size you want, can't you? Rrrr... I appreciate you giving me a nice handle to hold on to..." he murred. It was a side of Guard few had seen before, and Kosmo relished seeing it. "I can alter any part of my body... Wait and see just how tight I can make myself..." he said teasingly. Guard rose over him, his long, greenish dick hanging over Kosmo's own crotch before he brought it down and rubbed it against the morph's violet length. "Grrr... First, I'm gonna crush yours under mine..." he said, taunting the morph back! Kosmo sighed softly as the gargoyle thrusted its dick against his, holding him down as it grounded their hips together. It wasn't exactly rough, but it was certainly an assertive move. "Mmmm, yeah, crush me, tough guy..." Kosmo murred, while Guard grunted and growled as always, only the smirk on his face giving any indication to his emotion. This didn't go on too long before the gargoyle backed off, and lifted the morph's hips to gain access to his rear. "Grrrr... Now let's just see how tight you are..." he growled, holding onto Kosmo's sides tightly as he thrusted hard into his ass! Kosmo gasped loudly, but not in pain. He had prepared his rear for this, and for the moment it was actually quite accommodating. "Mmmm... Just wait... Entering might be easy, but pulling out..." he snickered, trailing off. Guard ignored him and got right to pounding his smug morph ass, taking full advantage of the current lack of tightness around him to build some early momentum. He murred in satisfaction, his balls slapping against the morph's ass with each thrust. "Rrrrr... All mine, punk..." he murred. Kosmo moaned softly in response, but for now there wasn't much stimulation in it for him. Soon, he began to use his morph skills to gradually tighten his anal passage, the increased resistance actually serving to boost the pleasurable sensation for both of them! "Aaahh... There you go... Now fuck me with all that hate GUN taught you..." he purred. Guard eagerly obliged, the gradual tightening serving to ease him into the more difficult thrusts, resulting in less of a loss of speed as he kept screwing the morph, holding him down as he tried to make Kosmo his bitch. Said morph moaned loudly, gripping the gargoyle's sides and letting himself be dominated with pleasure. His tail snaked up and tangled itself with Guard's, further linking their bodies together. Flapping wings accompanied Guard's thrusts as he sped up, getting closer and closer to orgasm. "Rrrrrr... Time to finish this!" he growled. Kosmo pulled him close, smirking. "Yeahhh, blast me, Agent Guard..." he murred, kissing him lustfully. Guard was surprised by the kiss, but let it happen as his last thrust hilted the morph below him, sending ropes of his hot cum flowing into him! Kosmo moaned loudly, his own cock suddenly spouting spunk up and onto Guard's chest, as well as his own! Once they were through, they rested on the bed, Guard panting heavily. "Grrr... This never happened..." he groaned. Kosmo chuckled. "So long as you don't try to arrest me tonight, that's fine..." he grinned, "Now, if you want me to keep quiet about you letting me go altogether... I get to be on top next..." he said with a devious smirk, making Guard whimper slightly...


When Sonic and Shadow arrived at Shadow Arc to confront Bucky, they found that the rat wasn't there. Lucky the cat, who was watching the lab in his absence, had no idea when he would return. "Some sorta fancy schmancy science exhibit... Something he couldn't go to when he was a fugitive." Lucky explained. Shadow looked at Lucky as though studying him, and soon seemed to decide that the cat clearly didn't know anything useful. "We might as well go, Sonic... I think this'll keep until Bucky gets back." he stated. Sonic nodded and followed Shadow as they headed back through the long, dark halls of Shadow Arc. "I just hope I don't turn female again before we catch that rat..." he whispered. Shadow motioned for Sonic to follow, and they turned a corner, sneaking their way to Bucky's unguarded laboratory. The lab had been cleaned out before Bucky left, though, so they couldn't find any clues pointing to what he might be plotting. "Well, this trip was officially a bust..." Sonic sighed. Shadow glanced at the door they'd closed behind them with a light smirk. "We should probably go... That feline could walk in at ANY moment..." he said, a playful tone to his voice. Sonic glanced at Shadow with surprise, but smiled back at him. He had turned into a female due to his attraction to the dark hedgehog, that much he'd concluded. Could they manage to have gay sex, though? "...I hear ya, Shadow... Kinda exciting, don't ya think...? Just...don't kiss me, to be safe." he said, remembering that it was the kiss specifically that seemed to transform him. Shadow crept close to Sonic and locked eyes with him. "...No promises..." he sighed.

They shot each other sexy smirks, and both quickly began to grow hard. There was no contest anymore at this point; Shadow had clearly won the competition between the guys, and now he'd claim his prize: Sonic himself. First, a bit of fun, though. He approached the blue blur and swiftly pinned him to the floor, his hand sliding down and wrapping around his hedgehood. Sonic reached back with a smirk and took Shadow's meat in his own hand. "Hmmm... First to say stop ends up on bottom?" the blue one suggested. "Hmph, why would we stop?" Shadow replied tauntingly. So, they began to jerk each other off, their gloved hands rubbing up and down each other's lengths swiftly, almost competitively. They gazed into each other's eyes, watching to see any cracks in each others cool demeanor. However, they both started to look nervous at once, neither wanting to concede or cum prematurely. "S-stop!!" Their voices overlapped, and they blushed, realizing they'd reached a tie. "...Then we both get a chance. But right now, I'm already on top..." Shadow smirked. Sonic grinned back. "I can last until my time comes..." he purred. Shadow flipped Sonic onto his belly, getting a perfect view of his beautiful blue ass. "Mmm... I've dreamed of this moment for so long..." he purred as Sonic raised his rear to him, as though presenting. "Well, I hope it's worth the wait!" Sonic said with a wink as he glanced back. Nodding, Shadow thrusted into the tight blue rear below him, gasping as he was welcomed by the warmth of Sonic's anal walls! Sonic purred at the penetration. All his experience with the others made it easy to adapt to such a sudden entry now! After pushing as deep as he could, Shadow then started to thrust in and out of Sonic, gripping the submissive hedgie's shoulders as he went. Sonic rose onto his hands and knees, moaning softly as the thick cock of the black hedgehog tunneled through his tight anal walls. Shadow rubbed the quills on Sonic's back, speeding up his thrusts gradually as he enjoyed Sonic's ass doggy-style. "Ahhh, yeah, Shadow... Show me that ultimate power of yours..." Sonic purred, loving every moment. In response, Shadow snickered and started pounding away hard and fast, panting heavily as he neared orgasm quickly. "Aaaahhh... S-sonic...!! Here it comes!!" he groaned, to which Sonic chuckled. "Go on... Gimmie your 'Chaos Blast', Shadow!!" he teased. With a few more thrusts, Shadow blasted his load into Sonic's rear, but that didn't slow them down much. After the entire load had filled his rear, and Shadow had pulled out, Sonic quickly turned the tables, putting the black one on his back! "My turn..." Sonic smirked. Wasting no time, he slid his length into Shadow's tail hole from this position, one that made hilting him difficult, but allowed him to gaze his dark-furred lover in his crimson eyes. They both let out pleasant gasps and coos as they were linked once more, though these sounds were accompanied by slight grunts from Shadow. He was typically on the giving end, and receiving was certainly something to get used to for him. "Hmmm... You're bigger than I thought..." he admitted, blushing up at the blue hedgehog above him. Sonic chuckled in response. "And you're not the tight-ass everyone thinks you are..." he said, mostly teasing. It actually was a tight entry, but Sonic pushed his way in, eager to give his mate just as good a fucking as he'd gotten. Shadow gritted his teeth and took it, exhaling with relief as the discomfort started to fade in favor of pleasure. They held onto each other as their gasps and moans mingled while Sonic's thrusts rapidly increased in speed! Sonic buried his hands in Shadow's fluffy white chest fur, while the black one gripped the blue-furred thighs of his mate, gazing up into emerald eyes with passion. They wanted to kiss, but the danger of Sonic gender-changing made them resist. Thrust upon thrust, Sonic kept going, building momentum until his cock throbbed with the urge to blow its load! No words were needed, a quick nod from Shadow was all they exchanged before Sonic cried out and let his cum flow into the ultimate life form's ass! In the heat of the moment, Shadow pulled him close and kissed him passionately, their tongues joyfully meeting in their mouths. When the moment passed, Shadow found that it was still a male Sonic resting atop him. "...Maybe I couldn't change while cumming?" he chuckled, nuzzling Shadow as he was held in the dark hedgehog's arms.

"What does this mean?" Shadow asked Sonic as they left Shadow Arc hand in hand. Sonic shrugged. "I dunno. I mean, Amy and Rouge..." he muttered, realizing full well they've had straight relationships going lately. Shadow nodded. "Maybe... We can have the best of both worlds..." he said, giving Sonic a light smile. Sonic smiled back. "I'm game to try... My ultimate boyfriend..." he smirked. Shadow nodded and put an arm around Sonic. "...Best prize I've ever won..." he thought.

The End!
