Years. It had been years. Years since Mewtwo had broken free of his captivity. Years since he had receded to New Island, using the same technology that had created him to create clones of all species of Pokemon. Years since he had met that trainer, that Ash, who had quelled the fire he had for revenge against humanity. Years since he had departed that island, seeking to better himself in complete isolation. He had years to think. He had years to ponder the relationship between humans and Pokemon. He had come to the conclusion that the two needed each other in some way, but the Pokemon was still stuck on the fact that it was so easy and simple for humans to abuse the relationship they had with their partners. For years, he had racked his mind, thinking of some way that bond could be reconciled otherwise. It took him so long to arrive at a possible solution. He had looked at the problem from every possible angle, analyzed it to see if there was any possibility for abuse. But thinking about his solution in a vacuum could only prove so much. He would need to TEST his solution. The solution, that perhaps the bond would be better preserved if Pokemon were the trainers to humans, rather than the other way around… He would need to leave his isolation to test such a thing, though. THAT was the sticking point for Mewtwo, the point of action. The Pokemon was paralysed by fear that something could go wrong… Until today. It was a wonderful day outside. The sun was shining. Pidgeys in the trees were chirping. A better day to venture back out into the world could not exist. It was today that Mewtwo stepped out of his cave, flying over the treetops and rivers in search of a human he could befriend, someone to use as a test drive of sorts for this plan. The routes today were surprisingly empty of trainers, but with enough searching, Mewtwo finally found someone. Plucky-looking, seemingly having just received their starter Pokemon. An idealistic mind, uncorrupted by greed or power. The perfect subject. The Pokemon needed to be careful, though. Seeing a Pokemon only spoken of in legends could give the trainer a heart attack if it wasn't planned out properly. He had a plan for what to do once contact was established, but getting that initial contact would be the difficult part… "Holy shit, a Mewtwo!!" … Hearing his trainer say that was a...surprise, to be sure. It was at that point the Pokemon realized that he had not been using the invisibility cloak he had brought along for this specific reason...oh well. At least the trainer wasn't screaming and running away like he had feared. Time to put his plan into action… The slack-jawed human watched as a purple wave of energy emanated out of Mewtwo, starting to flinch as he expected to get hit by a Psywave or something like that. But instead, there was a...strange feeling of vertigo that overcame him, as if the whole world was spinning...the human opened his eyes a few moments later. And everything was so much...larger. He thought it was some weird trick of perspective, so he closed and rubbed his eyes...only to find that, no, the world really HAD grown around him! Or, more accurately, that he had grown smaller...but, the most shocking and perhaps the most obvious thing was that the Mewtwo standing in front of him was now several times his size! The Pokemon was already a tiny bit taller than him already, but now that Mewtwo had done...whatever it had done, the Pokemon now dwarfed him! And, perhaps most shocking of all, the Pokemon was now reaching down to grab him, the human completely in the dark with the shadow being cast over him...he could try to run away, but there really was no point in it, so he just sort of cowered as the Mewtwo casually picked him up, the human feeling the world around him become even darker… A few moments of the world shuffling around him ensued, with the human starting to feel a bit dizzy...until that hand opened up. Sunlight washed over the human once more, before he was greeted by a large, gray head and a pair of purple eyes, staring right down at him… “Hello.” The voice felt like it was beamed right into the human's head, causing him to flinch a little bit at the sudden intrusive thought that was Mewtwo’s telepathy. “Do not be alarmed...my name is Mewtwo. I mean you no harm, but only wish to conduct a bit of an experiment...I have long thought that humans and Pokemon could not work together, but after a long period of intense thought, I have decided that perhaps there is a way for us to work together. “I believe, simply, that humans and Pokemon would be better together if Pokemon were the masters to the humans. I understand that this is a rather...radical, idea, so I would like to propose something to you. Become my pet for 30 days, and afterwards, if you do not want to stay as my pet, I will return you to your normal size and let you go. No questions asked.” The human just sort of lay there for a moment. It was tough to take in everything Mewtwo was saying while he was still dealing with the aftermath of having been shrunk to a fraction of his normal size, and it did take him a while to process it, but the main thing that he was thinking was that...he couldn't really deny Mewtwo’s request, especially with how vulnerable he was right now. Mewtwo could sense the human’s continued uncertainty, though, so he continued to speak. “I understand this is a bit much for you to take in right now. It is my aim to make sure that both sides of our potential relationship would be as fruitful and enjoyable as possible. I will give you plenty of time to consider and think this over…” “I’ll do it.” Mewtwo was surprised, but the human was even more surprised that those words had just managed to slip out of his mouth like that! He was always impulsive, but this was going a bit too far...! Regardless, if it had slipped out of him like that, it must have been what he truly felt. Mewtwo could certainly sense that, and the Pokemon was elated that he had managed to find such a willing(?) test subject on his first try...he had expected there to be a lot more pushback. And perhaps there would be a bit more in the future, if this human was as impulsive as Mewtwo thought he might be...but, it was a foundation for the relationship he was hoping to cultivate, for sure! “...thank you. I truly hope that we can become more than just a Pokemon and its trainer in time. I think I will name you...Aaron." Mewtwo said, before closing his hand around the small human once more and beginning to make his way down the trail. The human in his hand...he still had quite a few questions. Namely, how the Pokemon had managed to guess his name like that! But, he didn't have much time to experience a “traditional relationship” with a Pokemon, so, in this situation, maybe trying something a bit new wasn't so bad...! His choice to become a Pokemon trainer in the first place was pretty impulsive, so even though this was far a departure from the norm, it didn't feel that way to Aaron. And now he could lay back in the confines of, well, his new master’s paw, finding the smooth flesh to be oddly comfortable... Of course, Mewtwo put the cloak back on so that he wouldn't give any more trainers walking down this route a complete aneurysm. The beauty of nature, the world around him, seeing so many Pokemon being wild and free...it was something Mewtwo missed. It was something he thought about a lot, something that he had looked forward to for so long...so long, in fact, that he hadn't spent any time thinking about what he would actually use to, you know, store his new pet. Pokeballs were obviously out of the question, not only because he couldn't just walk into a Poke-mart and buy them, but because they probably wouldn't even work on humans in the first place. So, this little walk with his pet resting in his hand was a chance for the new trainer to figure out exactly what he was going to do with this tiny human… And, it took quite a while. But eventually, something did end up coming to Mewtwo. It certainly wasn't the most obvious or perhaps the most practical idea, and in fact, it might have been seen as a bit improper...but, he needed to show early that humans needed to be put in their place sometimes. So, Mewtwo made his way off the beaten path a little bit, finding a secluded forest area where Aaron and he could have a bit more of a heart to heart talk. And eventually, Aaron, who up until this point had been resting and absorbing everything that had just happened to him as the dark world around him shook with every step his new master took, felt his enclosure start to open up and allow the light of day inside once more. Those gray fingers folded away slowly, allowing the human to see that he and Mewtwo were surrounded by all sorts of trees, bushes, even a pond off in the distance. “W...where are we…?” Aaron asked, somewhat mumbling from the fact he was in and out of consciousness for a little bit there. Mewtwo was leaning against a tree, his soft, purple belly taking up most of the human’s point of view as the hand carrying him descended, descended, descended until...until the human saw something. A small slit, right in the underside of that belly, almost hidden between the Pokemon’s legs. And, even though there was nothing protruding out of it yet, and the human wasn't quite familiar with those aspects of Pokemon anatomy, he almost immediately had some semblance of what was going on. “Woah, hold up…” he said, bowling back a little bit as he saw something starting to peek out from the slit! This, this was going a bit too far too fast for Aaron! "L-listen. I dunno what you're planning right now, Mewtwo, but I think it's a bit too much for right now…" Aaron started to stutter as he continued backing up, quickly finding that he didn't have much of a place to GO inside Mewtwo's hand...unless he wanted to brave the fall down to the forest floor. And that seemed a lot worse than anything else right now. "Please try to stay calm, Aaron." Mewtwo said, as he reached down to his slit with his other hand, stretching it slightly and stroking at the tip of his shaft that was starting to poke out. "I have realized that Pokeballs are not a viable storage choice for you. I believe that the safest place to store you is inside of me…" the Pokemon continued, bringing Aaron closer to the tip of his shaft as the human leaned over the edge of his master's hand. "Y-you're going to put me in THERE?" Aaron questioned, watching as the shaft continued to grow and peek out of Mewtwo's genital slit...could he even fit inside there!? The opening didn't look that large...and where would he end up once he was inside? This, this was just WAY too much for him to take in at once. There was no WAY he was gonna do this… "Yes. For a short time, mostly while travelling. Do not worry, you will be safe and comfortable inside of me…" Mewtwo continued, sensing a hesitancy in Aaron's thoughts. "Please, trust me. A pet's trust in their master is a vital part to any relationship…" "Uh-no. That's just...that's just gross! Can't you get, like, a pouch or something!? I'm not gonna, gonna go in...there…" Aaron continued, sitting back and crossing his arms as he refused to cooperate. He had made this deal with Mewtwo, but he didn't sign up to be some sort of toy for the Pokemon! They had only met like, an hour ago at this point...this was going far too fast for what Aaron was comfortable with! Mewtwo sighed. He had expected a bit of pushback from Aaron once he thought of this idea, but it would only be temporary. He wished that the human would be a bit more trustworthy of him, but with all that he had been put through in such a short amount of time...it was understandable. Hopefully, some time inside of his master would relax the human and make him more agreeable to some of the...more unique ideas Mewtwo had in mind. For now, though, he would have to be a bit more forceful to get his pet to cooperate. The Pokemon’s eyes started to glow a deep purple as he attempted a bit of telekinesis, Aaron yelping out loud as that same purple glow enveloped his body and quickly started to lift him off Mewtwo’s paw! “Woah! Hey! What's the big idea…” he shouted, trying to free himself from his master's powers as that purple glow brought him closer and closer to the tip of Mewtwo’s shaft, now almost at full mast... “Aaron…” Mewtwo growled, his voice taking on a deeper tone as he was beginning to lose the tiniest bit of patience with his pet. He fidgeted with the human's body a little bit as it came closer to the tip of his shaft, the Pokemon reach him down and gripping the underside of it with one hand while Aaron floated in front of it, feet-first and right in front of the cock. "It's time for you to take a rest…" the Pokemon commanded, before pushing Aaron's legs down into his shaft with a wet *SHLRP*! The human groaned and continued to squirm as he felt his legs slip inside, the warm flesh of his master's urethra squeezing tight and threatening to clench and pull him deeper! "Nngh, Mewtwo, knock it off!..." Aaron yelled, trying his best to wrest himself from his master's control, but coming up quite short… Mewtwo's eyes glowed a deeper purple as he shoved Aaron a few inches deeper into his cock, the suckling flesh now wrapped tight around the human's waist. "That's master to you…" he said in a low, deep voice, making sure Aaron's squirms did nothing but pull him deeper into his master's cock! Aaron's hands were planted on either side of the slick flesh, trying his best to pull himself out as the environment around him was very intent on doing the opposite. "Hhf...master...please let me go!" the human said a few moments later, trying to adjust his language to be more respectful in hopes that would make things easier. He sensed a bit of approval from his master, before the cock clenched one more time and sucked Aaron a few inches deeper inside! "That's better...but I still think you need a rest." Mewtwo calmly replied, clenching his muscles tight and shllurrping up Aaron deeper inside! The human bulged out Mewtwo's cock quite nicely, and at this point it was getting a bit difficult to hide the pleasure the Pokemon was feeling from all of this! The musk of his master was starting to get to Aaron. Precum was leaking up from under the human's body, the stuff lubricating him up and making it even easier for him to slip deeper inside. Some of the stuff even got in his mouth at points, leaving a strong salty taste...god, he still couldn't believe what was happening to him! Just a few hours ago, he had been leaving his hometown with a Pokemon in tow, and now he was neck-deep in a Legendary Pokemon's bits...ugh, he didn't even want to think about where he was right now! But with his arms now trapped at his sides, Aaron could do even less than he was already capable of earlier...and, with all the warmth and tightness surrounding him, the human hated to admit it, but it...actually felt kind of good? Like a tight, musky sauna, constantly pressing against and massaging his entire body… Mewtwo could sense his pet's creeping enjoyment of this whole thing. He knew Aaron would come around, even if he was unsure at first...but, it was time for the human to curl up inside him for a while. Instead of using his telekinesis, though, Mewtwo placed one of his fingers against the top of Aaron's head, unable to stop himself from shivering in pleasure as he slowly pushed the last of the human inside, feeling his cock clench tight around the tip of his finger as Aaron disappeared inside his musky, warm shaft. "You'll be warm and safe soon, my pet…" Mewtwo said, feeling the human still wiggling and squirming inside the tight confines of his cock, the bulge he made gradually descending as Aaron sank further and further into his master's loins. The tightness was so overwhelming for Aaron. There was so much sensory information being thrown at his body at once, he had no real hope of processing it all...but, it ultimately did start to feel kind of good! The heat was sweltering, sure, but the warm flesh of his master's cock was surprisingly gentle, pushing and ushering him deeper inside his master, massaging against every side of his body...ugh, he couldn't believe that he was actually starting to enjoy this a little bit! It really did feel warm, and comfortable, and safe…the human idly wondered where exactly this tight waterslide would lead as he tried his best to snuggle up against the shaft walls, the bulge he made in Mewtwo's shaft starting to disappear into the Pokemon's slit… Mewtwo exhaled gently, moving his hand away from his shaft as he felt his pet sliding deeper into his loins. Soon, Aaron would be curled up inside the best Pokeballs money could buy!...heh. Though he could make a pun now, he really did believe it was the safest place for his pet to be. He sidled up against the tree a bit, getting ready for a rest after the events of the day. A few moments later, Aaron felt the flesh around him lurch a bit, squeezing him even tighter before pushing him through a narrow opening into a new chamber. He didn't...really know where he was at first, warm musky fluids sloshing around inside the chamber along with him as the human started to curl up into a ball, the flesh surrounding him massaging him even more powerfully than the shaft was! "I hope you are comfortable," Mewtwo's voice came, startling Aaron with its clarity before the human realized that he was still using telepathy. "You are currently inside my internal sac. Please, try to get some rest while I do the same." Mewtwo continued...yeah, that wasn't too surprising. Aaron was glad this wasn't the bladder instead, at least! The musk of his master was even stronger inside here, every breath laced with the powerful pheromones...they made him feel kinda loopy. Loopy and happy. Allowing him to sink into the walls that were massaging him, bathing in those warm fluids and starting to slip off into sleep... "What is your greatest dream, Aaron?" Those words jerked Aaron back to consciousness. It could have been minutes or hours since he fell asleep inside of his master; the lack of daylight made it hard for the human to tell. He did feel quite rested, though, those walls massaging against his body at every turn, spreading a lovely feeling throughout his whole body...the voice was that of Mewtwo's. "...I know I couldn't hear you if you physically spoke in there, so please, just think to communicate with me right now." Mewtwo's voice came again, still startlingly clear from how it was beamed into the human's mind. "Well...I suppose, like a lot of other trainers, I wanted to become the League Champion. Travel the world, battling gyms...that sort of thing. Before all...this happened, of course." Aaron eventually thought, raising an arm out of the goopy pool of cum that he was bathing in to accentuate his pause. "Also, uh, can I come out now?" "In time, Aaron…" Mewtwo said as he walked along a forest trail, deep in thought. He could sense the human's growing impatience, the warmth and comfort of his sac starting to wear off a tiny bit and make him a tiny bit more rebellious. "I suppose, that is a noble goal...forge bonds between trainer and Pokemon, through the art of battle." the Pokemon eventually said. "I think I have a way you could still accomplish that goal…" Aaron perked up when he heard that last part. Really? Well, he guessed he could do whatever when the 30 days were up, but getting Mewtwo to help with this dream of his...well, that would be perfect! He started to get even more fidgety, wanting his master to release him so he could get to...work? Training? What exactly did Mewtwo have in mind? "I can take you to the gyms throughout Kanto. Battle alongside you, as 'your' Pokemon...take you to the Indigo Plateau. We could be unstoppable…" Mewtwo continued, knowing that he could defeat any trainer without putting forward too much effort. Doing it to please his pet was just icing on the cake! "But, I would want something out of you as well…" "Yes?" Aaron replied almost immediately. He had already become Mewtwo's pet...anything else the Pokemon could think up was comparatively small potatoes! He would do anything to become the League Champion, a trainer all trainers looked up to as a perfect example of the relationship between Pokemon and trainer. He wanted to BE that example! "I would need you to...become more accepting of your role as my pet." Mewtwo eventually said, after ruminating a bit on the best way to explain to Aaron what he wanted. "To become League Champions, our relationship must grow and flourish...and disobedience is the quickest way to deteriorate that relationship. You must be willing and ready to do anything that I ask, and trust that I have your best interests at heart, even if what I ask may seem ridiculous or even dangerous. "That is the only way we can become Champions together, Aaron. Do you accept these terms?" The human took some time of his own to ruminate on what Mewtwo was asking. His brain was still so overwhelmed with the events of the previous day or so, that he couldn't even really comprehend what Mewtwo could ask of him that was more outlandish than what had already happened!...but, far stranger things had already occurred. It was a tough ask, to be sure, especially so early in their relationship still...but, Aaron had dreamed of being the League Champion ever since he was a kid! And Mewtwo was more than powerful enough of an ally to get it done...it was like Mewtwo had said. He would have to trust him. Even though they had only known each other for little more than a day, he would have to trust him. It took some time for Aaron to think. Once again, he phased in and out of consciousness, massaged by his master's sac walls into a state of lethargy and relaxation. But, rest often helped him think things over, and by the time the human awoke once more, he had his answer. "I'll do it."
