Mewtwo had been bested for the first time in its life, defeated in battle by Pokemon Trainer Red and his Lucario, and then transformed into a female using a strange mega stone and raped into submission by the victorious aura Pokemon. The genetic cat could potentially have been captured there, but Red left instead, referring to more Pokemon that he would revisit Mewtwo with. "The battle... being defeated... it was a rush I have never felt." Mewtwo admitted to himself as he waited patiently at the back of Cerulean Cave for Red's return. "...I do not plan to lose again, but yet... I want to feel that rush. I want to be pushed to my limits. Perhaps this trainer is the answer I've been seeking..." he mused, sitting with his tail swaying back and forth behind him. Most of all, he wished for an opportunity to face Lucario again. "...He humiliated me, utterly and completely. When we meet once more, I will either return the favor... Or reveal his full superiority, and succumb before it, as his mate..." he shivered, catching himself smiling slightly. Both ideas excited him in different ways. But which excited him more? To reassert himself as the most powerful Pokemon, or to allow that facade to fall away and become the submissive mate of a rival? He purred softly, imagining Lucario's powerful body pressed against his again. In his mental image, he could not determine which Pokemon was male and which was female. He pictured their hips locked together, such closeness that an observer could not tell where one Pokemon ended and another began. He gasped as he caught his thoughts growing more intense, and crept to the edge of the land mass he inhabited to splash some water on his face. "...When will the human return to challenge me again? This wait is messing with my mind..." he thought.

Eventually, Red did indeed return, his Pikachu lighting up the cave as before. "Hello, Mewtwo... How did you rest?" he asked. Mewtwo chuckled. "If your goal is to capture me, you should not allow me to recover." he stated. Red smirked. "I'm gonna catch you on MY terms..." he said. Mewtwo crossed his arms and floated in midair. "...Is it Lucario, then? Are we to have a rematch?" he asked. Red shook his head, reaching for a Poke Ball. "I said I'd bring different Pokemon... So this is very different!" he said, tossing the ball and unleashing his Pokemon! It was still blue, but it wasn't furry. Rather, this Pokemon was amphibious. It was the ninja frog, Greninja! "...You have travelled far, haven't you?" Mewtwo realized. Greninja pulled its long tongue into its mouth and stood tall, looking up at Mewtwo with a smirk. ("Lucario didn't oversell you... You will be quite a mate!") he said in Pokemon language! "...We shall see..." Mewtwo retorted.

Mewtwo started the battle by attempting a psychic attack, but Greninja simply charged through it without flinching! "A dark type... How typical." he said, floating up high to evade Greninja's charge. The frog turned and hurled a Water Shuriken up at him, which he repelled with a well aimed Psycho Cut. Red was simply gesturing to Greninja in order to command it, he had it well trained. "Interesting tactic... Keeping me in the dark on your strategy, hm?" Mewtwo mused. Greninja fired a Hydro Pump up at Mewtwo, which he floated away from easily. However, the watery blast had steered him to the ground. Mewtwo didn't just wait there, though; He hurled an Aura Sphere at Greninja, hoping to take it out handily. Instead, the attack struck a Substitute doll, and then Greninja charged ahead and struck Mewtwo with Shadow Sneak! The psychic cat grunted, but chuckled as well. "No dark type moves?" he realized. "No... but Greninja is fast!" Red grinned. Now that Greninja was at such close range, Mewtwo thought to finish it with Aura Sphere, but instead, Greninja vanished in front of him! "...What!?" the feline gasped. Greninja tore into Mewtwo repeatedly with Shadow Sneak, striking and then vanishing again like a ghost, while Mewtwo winced and groaned helplessly! Soon, the genetic Pokemon was knocked to his back with one final strike, and Red stood ready with the Genderite Mega Stone. "Sorry, Mewtwo, looks like I win again! Now... show us your lovely other forme!!" he said, touching the stone on his Mega Ring to activate the Mega Stone!

With a flourish of bright light, Mewtwo transformed once again, his body losing its masculine features in favor of more feminine parts. His pecs expanded into lovely, round breasts, while his sheath widened and reshaped into a wet female vagina. A gasp came from the genetic Pokemon, and Red could swear that even its voice became higher in pitch as the transformation was completed! Mewtwo laid on her back before Greninja, totally prone and totally sexy in her female forme. The ninja frog smiled wide, his poke-cock unsheathing quickly as he observed Mewtwo's transformation and resulting hot body. ("Quite a prize I have won... Too bad I will have to defeat Lucario for the honor of being your permanant mate once you have been captured...") he said as Mewtwo stared up at him. "Prize...? Only if you can claim me!!" she shouted, attempting to throw one final Aura Sphere in a last ditch attempt to prevent a second humiliating defeat. However, Greninja simply swiped his long tongue across her body, starting between her legs and slowly moving upward. Mewtwo was stunned, and fell backward in shock as the tongue carressed her belly and moved up to her breasts, teasing her nipples, making her gasp lightly from the sensations. Her last offensive was stopped in its tracks, and since she was already weak from the battle, Mewtwo was Greninja's for the taking. The frog continued to play with her breasts using his long tongue, wrapping it around one, and then snaking it around the other before squeezing them both! He had to lean in a bit to pull this off, but the shocked look on Mewtwo's face and her groans of submission made it worthwhile. Now, he was ready to take her!

Greninja held Mewtwo down on the ground. She had a bit more energy left than she'd had with Lucario, but her psychic attacks couldn't budge Greninja, so all she could do now was struggle in vain. The ninja frog licked her face, surprising her and slowing her struggling long enough for him to line up his cock with her entrance. ("...Perhaps if I successfully impregnate you, there will be no need to battle Lucario...") he grinned as he thrusted his hips, plunging his amphibeous dick deep into Mewtwo's wet passage! She cried out, mostly at the idea of impregnation, and resumed struggling with whatever might she had left! Greninja pinned her down, holding her arms still with his webbed hands. Then, he started thrusting his hips, his frog phallus invading deeper into her depths with each motion. Mewtwo could do nothing but moan in time with the thrusts, looking away from Greninja to hide the look of shame on her face. ("Look at you squirm... You're surprisingly shy.") Greninja stated, softening his grip slightly as Mewtwo glanced back at him with confusion. What did he mean, shy? He was RAPING her! Then again...she had technically agreed to these terms at the start of battle. She knew the penalty for losing this time. It might not be Lucario, but... maybe Mewtwo had wanted this from the beginning? Greninja slid his cold hands up her arms and carefully rested them at the sides of her breasts, tickling her a bit with his webbed fingers. Mewtwo started to ease her tension a bit, parting her legs a bit more accomodatingly and gently holding onto Greninja's arms with her three-fingered paws. "Aaaahhh... Your dark power... was the first of its kind to overwhelm me...!" she panted, blushing, "Keep it...unnnh...up! Claim your prize, my champion!" Greninja smirked at this, sending his long tongue to slurp her nipples, her neck, and then leaned in to kiss her properly before speaking. ("I haven't overwhelmed you quite yet! I aim to conquer you on this battlefield, as well!") he said, pressing her breasts together between his frog flippers and making Mewtwo moan even louder!

Asserting his dominance further, Greninja swiftly flipped Mewtwo onto her hands and knees, and pounded into her pussy once again from behind! Red was very much enjoying the show, to the point that he was rubbing his own crotch through his pants, and seemed to very much want to pull them off and join the fun. However, this was Greninja's prize, and he kept thrusting deeper and deeper into the feline Pokemon, hoping to get his seed to launch all the way to the target! Mewtwo's gaze stayed fixed on the dirt as she was getting fucked doggy style, and she kept moaning encouragement to her conqueror throughout. "Unnngh... Oohhhh!! W-wonderful!! Punish me... Aaaahhh... Oh, Lucario!!" she gasped. Greninja clasped her waist tightly at hearing Lucario's name instead of his. ("No... I'm the one you should cry for! It is Greninja's power you are feeling!!") he grunted, speeding up his thrusts in the hope of gaining Mewtwo's favor. Red watched the psychic Pokemon's breasts swing back and forth as Greninja pounded her faster, the buldge in his pants getting uncomfortably big as he did. Mewtwo panted and moaned, feeling her walls tighten as Greninja was pushing her over the edge. The ninja frog pushed a bit hard, too, and with a loud pop, he'd knotted Mewtwo! "Nnnngh?? I was unaware amphibian Pokemon had those!!" Mewtwo gasped as they were locked together! ("Now, you are mine...!!") Greninja panted, crying out loudly as shot after shot of Greninja cum was pumped deep into her inner sanctum! Mewtwo's upper body collapsed to the ground with a lustful groan as her own climax followed, splashing her juices against Greninja's crotch! The psychic cat held her belly, feeling quite full after that pounding. ("May our children grow strong... And may we produce many offspring as mates!") Greninja smiled, extending his tongue tenderly to lick Mewtwo's cheek. 

Red called Greninja back to its Poke Ball, releasing Mewtwo from its knot. "Don't get excited... I'm pretty sure you and Greninja are totally incompatible. You'd never get pregnant from him." he said. Mewtwo sat up, blushing softly. "...Are you going to capture me soon?" she asked. Red nodded. "Not today, beautiful... But that day is comin' fast. I hope you're looking forward to it!" he smiled, waving as he turned to leave. Mewtwo had remained female this time, and as hours passed, the Genderite didn't seem to wear off. Fortunately, there seemed no evidence that Red was wrong about Greninja. Mewtwo didn't feel...pregnant. "...Has my body decided? ...Am I female now...?" she wondered that evening. As she laid down to sleep, her fantasy of Lucario came to mind again. Only now, it was clear that Lucario was male, and Mewtwo was female... and utterly submissive to him.

End.
