This story has reached its conclusion. There are 2 different endings. This is the "Mewtwo Mastered" ending, while the other is the "Mastered by Mewtwo" ending. It probably should be self-explanatory, but this one features Mewtwo's ultimate capture. It also features bestiality, so, yeah... The alternate ending, posted separately, is a more unexpected event. There's still rule 63, but no bestiality. I wonder which ending you'll prefer?


Having exited the Rocket base near the power plant, Red was eager to hear what Mewtwo thought about joining him now that he had bonded with his Lucario. Mewtwo had thought hard about the possibility. Red had proven himself capable enough to defeat Mewtwo in battle more than once. He was a powerful trainer. But was he worthy of Mewtwo's power? The feline Pokemon looked at Red seriously as he gave his answer. "If you wish to be my master, you must first master me..." he stated. Red looked a tad confused. "I've already beaten you in battle..." he said. Mewtwo nodded. "That is one part. Now, you must prove that you can control my power..." he stated. Red nodded. "Okay... How would I do that?" he asked. Mewtwo smiled. "Pin me... Without your Pokemon." he challenged. Red looked a tad shocked by the idea. "You can just fly out of my reach!" he pointed out. "I'll give you a ten minute head start before I fly away. Pin me down, if you would master me." Mewtwo insisted. Red wasn't sure if this was even possible without Pokemon, but if Mewtwo was testing him, he felt it would be foolish to refuse. "All right, Mewtwo... I'm a champion, I can take whatever you dish out... So watch out! Here I come!" he said with determination!

Red charged at Mewtwo, and the Pokemon stood firm until he got close. "Too slow..." Mewtwo said, picking up Red with Psychic and tossing him back a short distance. Red picked himself up quickly. He wasn't too surprised by this move; he was just getting a feel for how much resistance Mewtwo would put up. He charged again, getting the same result. "If this is all you can do, then humans are as weak as I feared..." Mewtwo sighed. Red stayed low for a moment this time, and quietly grabbed a handful of dirt. "We aren't very strong... But we're smart!" he said, jumping up and to the side while tossing the dirt at Mewtwo's face! The psychic Pokemon stepped aside to evade the "sand attack," but this distraction allowed Red to get in close and jump at Mewtwo, grabbing onto the Pokemon's body! They started struggling, Mewtwo trying to psychically remove the trainer, but he maintained a grip on the cat Pokemon's arms with his hands! Mewtwo laughed a bit. "You'll tire this way, and you'll never truly pin me..." he taunted. Red knew this was likely true. He had to think. He couldn't use Pokemon, but what could he use? Poke Balls wouldn't work. Berries were pointless here, as were potions. Most of the things in his bag seemed useless at the present. Finally, he came to one last-ditch conclusion. "I have one move...left!" he smirked, releasing his grip on Mewtwo with one hand to grab something while holding on for dear life with the other. "The ten minutes are almost up..." Mewtwo warned. Suddenly, Red touched something to his wrist, and a burst of light enveloped them both! Red had used the Genderite one last time, and got to watch the transformation from within the light. Mewtwo's chest expanded, once more sporting glorious white-furred breasts, and as his body took on more feminine curves, a slit emerged between his--HER legs. When the light faded, Mewtwo stood in bewilderment, and Red took advantage of this state to swiftly tackle her to the ground, holding her arms with his hands and her legs with his knees! "...What do you say now?" he asked slyly. Mewtwo sighed in defeat. "I say... Take me, Master..." she sighed.

Red blushed. He was sure Mewtwo didn't mean it the way it sounded. She probably meant she would allow herself to be captured now. Still, it wasn't an unattractive notion. Pinning her like this, he could really get a feel for Mewtwo's strong, yet strangely sexy feline body. The genderite had led him to take interest in his Pokemon like this before, but he was normally content just to watch them screw each other. Suddenly, he was overcome with a new urge. He had mastered Mewtwo in every other way. Could he truly be her master... like this? His pants suddenly felt a bit too tight, and he knew what he had to do. "Okay... Whatever you say, Mewtwo..." he said, opening his pants and removing his coat. Mewtwo watched him with wide eyes as all Red's clothes scattered around them, leaving only a hat covering his head. "Your master is ready!" he said, while Mewtwo spread her legs a little bit. "Show how you've mastered me... And I will be yours to use as you wish!" she said with a smile.

Red ran his hands over Mewtwo's lightly furred body, feeling her curves and caressing her sides. His cock was hardening fast as he felt the thrill of holding this sexy feline below him. Mewtwo glanced him over, blushing at the sight of his growing dick. "Oh, master... It... It's bigger than Lucario..." she gasped. Red smiled, and lined up his cock with the psychic Pokemon's entrance. "I've been training for a long time... I have grown since I left home at the age of ten, huh?" he mused. He thought back on how his journey had led up to this moment, but only for a second before thrusting his great rod into Mewtwo's pussy! She gasped at the penetration, her paws reaching for the trainer's hips. "Ahhhnn..." she whimpered, but then smiled up at him awkwardly, "It...fits perfectly. Take me with all your power, master... I can handle it..." she purred. So, the trainer started to oblige, holding the mighty cat Pokemon down as he slapped his hips against hers repeatedly, pushing his way deep into her tight passage! Mewtwo let out soft gasps as her new master took her. The feel of his human organ inside her was unlike her previous mates, it was thicker and massaged her walls more thoroughly, making her struggle to keep her tough composure. Red watched her squirm under him, and wanted to see this tough facade broken. He moved his hands to her chest, rubbing his fingers over Mewtwo's soft, lightly furred breasts. This coaxed a light purr from the cat, and she whined as she felt her tough image crumbling. "M-master... Ohhh... H-harder..." she said, blushing, trying and failing to sound commanding. The human chuckled, releasing her breasts and gripping her hips, speeding up his thrusts while Mewtwo laid back and took it. "This... is just the beginning!" Red panted, smirking. The feline wailed as her sweet spot started getting struck repeatedly by this human who was barely able to pin her! Her breasts bounced with the momentum of the fucking, making her turn red with embarrassment as Red watched this. Her new master could only last so long at this pace, and soon he blasted his first cumshot into Mewtwo's pussy, both of them moaning as his seed flowed into her! Mewtwo's tail coiled around his ankle, and her paws stroked the trainer's sides. "I am yours, master..." she whispered, nuzzling his neck as he laid atop her.

However, Red wasn't finished. He would make this first time with Mewtwo truly memorable, so after taking a moment to catch his breath, he then climbed along the feline Pokemon's body and slid his cock into her cleavage, starting to titfuck her! Mewtwo purred softly as his head poked out from between her breasts again and again, and she leaned in to lick it every so often, making the trainer moan softly in approval. Red grasped her breasts in his hands and thrusted furiously, giving her a rough titfuck until he decided to move on to another position. Next, Mewtwo was riding his dick while Red held on to her wrists, keeping control of things even while the cat Pokemon was on top. He watched her boobs bounce up and down as she slid back and forth over his rod, panting and moaning very submissively. "Aaahhh... M-master... You are so much stronger... Oooohh... Than I anticipated!!" she gasped, impressed with his endurance. "Get used to it... We might be doing this more than battling!" Red smirked, moaning in pleasure as he enjoyed the talents of his new Pokemon. Soon, he switched them to yet another position, taking full dominance by fucking the cat Pokemon doggy style. Mewtwo blushed with embarrassment at the trainer's feet, on her paws and knees as he slammed his cock into her pussy, his balls slapping against her repeatedly as he went! He leaned over her, his hands caressing her furry body as he kept thrusting into her. "Aaaaahhh... M-master!!" Mewtwo wailed as she came, her juices splashing against the ground. "You're mine..." Red whispered, his own load joining and filling the feline Pokemon one more time before they both collapsed.

Thoroughly satisfied, Red got up in a few minutes and went to his bag, tossing a Poke Ball at Mewtwo seconds later. With a flash of red light, the legendary Pokemon entered the ball, and with barely any shaking, it clicked shut, confirming the capture. The trainer smiled as he picked up the shiny ball along with his scattered clothes. "...You'll never be alone again, Mewtwo... We both won this battle." he said, unsure if the Pokemon could actually hear him inside the ball or not.

The End
