Bill’s Research
       
       It was late at night on the road to the Pokémon League. Most pokemon in the area were resting peacefully, and there wasn’t a trainer in sight. In fact, with most of the pokemon nesting in the tall grass, the only creature in sight at all was an exhausted nidorino that had laid down in the middle of the road. 
       
       “Ugh… of all the times for Oak to be out of town.” The nidorino complained in remarkably good English. Being able to speak didn’t help him now though, and it hadn’t helped him much on the way here either. Either he was swarmed by children before he could get a request for help out, or he was pelted with pokeballs by every overeager trainer from here to cerulean city. “I don’t know if I can make it any farther…”
       
       The nidorino had collapsed a few minutes ago after swimming his way across the small pond that led to the league. He’d never been a strong swimmer, even before the accident. These new, stubbier legs weren’t helping things at all. 
       
       Bill didn’t usually regret his attempts to advance the field of pokemon science, but right now he was wondering what he had been thinking creating that teleporter. Granted, he couldn’t have ever predicted that it would end up fusing him with a nidorino. He couldn’t have even predicted a nidorino wandering into his lab, much less pushing him into the pod before it was ready. 
       
       Yes, it wasn’t the experiments that were at fault, it was just the circumstance. He couldn’t very much blame the nidorino even. Cute as it was, it would have to be blameless. 
       
       He lifted himself up. “Yes, just experimentation trying it’s best. Think of it as just another hiccup.” He spoke aloud to encourage himself. “Just another mile to walk on the road to progress.” He grinned to himself, proudly baring his fangs, and lifted himself up to continue his journey. 
       
       Then he promptly collapsed. In spite of, his attempts at finding more energy, the path in front of him was just far too long to traverse at his current strength. He wouldn’t have expected to make it on foot before, but he had hoped his new body had a bit more stamina. It had, admittedly, since he made it here all the way from Cerulean, but the strength the nidorino gifted him wasn’t quite that impressive. 
       
       He would need to note the experience of exhaustion as a pokemon later. However, for now, what he needed was rest. So, groaning, he turned to look for a place to nest for the night. Up until now he had avoided the tall grass as best as he could, uncertain how wild pokemon may react to him. For now though, he reasoned it was probably better to wake up to a fight than in someone’s pokeball. After all, his hardy nidorino skin would keep him safe, most likely. 
       
       Perhaps because of his exhaustion he was able to sniff out what smelled like a good spot not far from him. It was funny how he hadn’t even thought to pay attention to his nose since he found himself to be a nidorino. Now, it seemed like it was sending him signals through some sort of primal instinct. Though, it was hard to put words to the smell.  It simply signaled safety. 
       
       Bill followed the instinct to move toward that safely more out of curiosity than drive. Thankfully, his body listened to it without question, sniffing his way to a small patch of grass not far from the road. It was already tramped down and comfy. Bill didn’t have to waste any time thinking before he curled up cheerfully on top of it. 
       
       Once he was comfortable, he was allowed to question though. “Wow! Pokemon’s instincts really are incredible, aren’t they? As a nidorino I knew just where to go without even having to think.” He smiled and shut his eyes to finally rest. “And it’s so comfy too.” Allowing his eyes to close was the final straw for the young scientist’s exhausted body. He didn’t fight sleep as it came. His mind merely wandered pleasantly to thoughts of his salvation, of Oak, and the league, and his teleporter. 
       
       As one does not question dreams, he didn’t question the elderly nidoking in the lab coat who helped him out of his predicament, and he didn’t question his beloved abra playing by his side, teleporting to and fro. He just enjoyed the smell of grass in the field while Oak watched him and his best friend play.  
       
       “Nido…” The nidorino blinked his eyes open when he felt something poke at his side. Bill wondered for a second if he had made the noise that woke him up. His ear twitched when it sounded again though. “Nidorino?”
       
       “Right, right…” He mumbled as he blinked away the dream. “I’m not a pokemon. I’m Bill… nice to meet you.” He yawned, unsure who was speaking to him.
       
       Another poke in his side brought his attention to a nidorino who was rather aggressively trying to wake him. “Nido!” Once he’d turned, it lifted its head and locked eyes with him. The action communicated his problem pretty clearly, though for some reason Bill was reasonably certain the pokemon wasn’t angry with him.
       
       Maybe that meant it could be reasoned with. “Oh! This was your spot then? I took it from you when you went stepped out?” He was too groggy to really stand, so he just nodded. “You have my utmost apologies, but I’m too tired to move. Can I share it for the night?”
       
       “NIdo. Nidori.” The pokemon continued to glare at him and shook its head. Despite the rather simple communication, Bill got the message perfectly. Though, he was a bit thrown off by the way the nidorino smiled. He was sure it wasn’t a threat like when many pokemon bared their fangs. But if that was the case, it didn’t match with the message.
       
       “So, it’s not your turf, it’s your boss’s? And he doesn’t like sharing?” Bill responded slowly making sure he got the whole message. When the nidorino’s expression didn’t change, he took it as confirmation. He pondered his options for just a moment, but his brain was still sleep addled. He couldn’t easily find somewhere else to go, and this could be a great opportunity to study pokemon hierarchies. “Maybe I could talk to him? He’s a nidoking, right?”
       
       The nidorino shook his head. “Nido, nido…” He shut is eyes for a second and growled. It was a soft growl though. Bill felt it looked almost like he was chuckling. When he looked into Bill’s eyes again, he definitely had a smug look to him.
       
       “A bad idea, huh?” Bill blinked slowly. So, this nidoking wouldn’t tolerate him in his territory? He wondered briefly if he perhaps should just leave, but he was becoming more curious by the moment. “Well, I think I should insist. He can’t be that bad, can he?”
       
        The low, soft growl grew just a touch louder while the nidorino continued to shake his head. Bill had already read the warning, but now the smile the creature wore began to feel more like a threat. Then, it moved closer to him, bumping muzzles with the researcher briefly before moving past to press into his neck. Close as the pokemon was, the growling was beginning to make Bill’s ears twitch. The arousal was suddenly unmistakable in his voice. In fact, it was so clear that Bill wondered how he had missed it before. 
       
       Once he did notice it, the new pokemon suddenly felt a bit of his energy come back, just enough to jerk away from the aggressive nidorino. Unfortunately, he didn’t have nearly enough strength to run, so all that came of him pulling away was him locking eyes with the eager pokemon. The nidorino continued to growl, his message more than clear. “Y-You can put in a good word for me?” Completely unfamiliar with this situation, Bill was unsure how to proceed. He opted to be polite. “I appreciate your offer, but-”
       
       A claw landing on his head and smashing him firmly into the ground dismissed that attempt quickly. “Nidorino!” It had been pretty obvious from the moment he’d asked that leaving wasn’t an option. The nidorino decided to drive that point home by grinding its sole against Bill’s head though. It even made a point of flicking it against the new pokemon’s horn when it pulled it off too. Bill was stunned to find out just how much that shook his skull. 
       
       Bill whined a very inhuman whine once the nidorino finally pulled away. The headache left behind left him reeling badly enough it was hard to open his eyes, not that he was certain he wanted to. The nidorino’s growling made him too nervous to leave them closed though, so he forced them back open and tried to lift his head as much as he could.
       
       He couldn’t call what he saw next a surprise exactly, but it was shocking. The nidorino had backed away just enough to lift a hind leg and show off a frighteningly large, pink erection and sheath. He was so frightened at that moment he couldn’t begin to think of what to do with this information. Of course, what the nidorino wanted was obvious, and there was something gnawing at the back of Bill’s head that told him to give it to him. He would have guessed it to be fear, but somehow it felt more primal than that. 
       
       “Ni-nido…” Bill shook, surprised at the strange call he made. He was somewhat more surprised by the way his body moved though, pressing his snout forward until it rested softly under the nidorino in a show of submission. He closed his eyes again, embarrassed at the action and the way being this close to a stronger male made his body tingle. 
       
       Then the nidorino barked at him. “Ri!” It was vicious and dominant. Worryingly loud too, but Bill couldn’t think much beyond submitting now. It was curious how much the hierarchy dominated his mind. He wondered if such a thing was natural among nidorinos, submitting to the strong. It certainly wasn’t something he found familiar in himself. Was that why they had kings?
       
       Familiar or not, the feeling was somehow enjoyable. He decided to explore it, scared as he was, he was becoming more curious. His body still seemed to move on its own, reaching out slowly with his tongue and wrapping around the base of the nidorino’s cock. He observed almost passively while a series of feral groans escaped his throat and his body quivered. 
       
       The nidorino continued to bark at him to lick the whole time, encouraging his tongue to wander all about the pokemon’s length. He was definitely making sure he took every chance to establish his dominance, even patting Bill with his foot again, albeit not as roughly as before. He even tasted dominant somehow. Bill had difficulty explaining that, but something about his pokemon body responded to the pheromones reflexively. They made his stubby little tail twitch. 
       
       “Nidorino!” The barking grew even louder and the pokemon started to kick. Its hips moved with a vigor that made it hard for Bill to keep up with his licking. He managed though, even while the soft underbelly flicking against his horn made his brain quake. He wondered briefly if he was hurting the other pokemon, but it was clear his horn barely tickled, or the nidorino wouldn’t keep going. Only he got to suffer in this particular show of dominance. 
       
       The idea of that was fascinating, naturally. What alarmed Bill though was how arousing it was as well. The tickling headache made it hard to focus on his observations, forcing him to become more aware of his twitching tail and the erection pushing against the dirt beneath him. It was like he was somehow born to be submissive. Perhaps some nidorinos were? Or maybe it was just something that went along with the larger pokemon’s show of force.
       
       Whatever it was, he was more than happy to go along with it now. It was like he had no other choice. His body was begging for far more than just licking too. He knew it in the way his tail twitched. He’d never even thought of sex with another man before, but this pokemon body absolutely demanded it. Maybe if he did good enough at the licking?
       
       Bill growled out something instinctually and his body started to wiggle. He knew it was a communication of submission, and he was pretty sure it got his desire across. 
       
       He expected the nidorino to growl out something back to him, another show of dominance. He was surprised when it instead just yelped, seemingly scared. He didn’t stop licking though. The dick was shaking in front of him. Instinct told him to finish what he started, and he had to admit some curiosity about seeing a pokemon cum up close. 
       
       Soon enough, his curiosity was satisfied. The nidorino came with a surprising desperate sounding call. “N-Nido! Nido!” He also came with a surprising amount of restraint. At first the dick just splashed a pitiful spurt onto his nose. It took a few more licks before it started properly letting loose. Bill savored the dominant smell of it as it landed on his face. How much he enjoyed it was embarrassing, but thankfully no one beyond this pokemon would know.
       
       At least, that was what he thought. He was rather taken by surprise when he felt a massive claw on his backside. It should have surprised him enough to make him freeze up. In his mind he was utterly terrified by the grip’s force. However, his body just growled softly at its touch, tail still twitching. 
       
       Then the owner of the claw spoke, revealing themselves. “Nidoking…” It spoke in a slow demanding tone as the pokemon lifted the other nidorino away from Bill. Nidokings had always looked massive, but from the perspective of a smaller pokemon seated flat on the ground, the beast looked like a true monster, or maybe a monarch. 
       
       “N-nido.” The worn out nidorino was sweating and squeaking some sort of apology to the nidoking from the look of it. His eyes were closed, and it looked like he was trying to smile. Bill wasn’t certain what he was apologizing for at first, as addled as his brain was by shock and arousal. However, things became very clear when the nidoking responded.
       
       “King!” It was a statement that, fascinatingly, rang true in both languages. The nidoking squeezed Bill’s ass as he let the declaration of rule, and the nidorino hung his head. Bill’s body wanted to as well, but he couldn’t bring himself to look away. His eyes wandered all over the regal pokemon, taking in everything from his proud smile to the nidoran and nidorino gathered at his feet, to the massive dick sitting between his legs. 
       
       As the king’s claw wandered higher up Bill’s ass, scraping ever so lightly under his tail, Bill increasingly couldn’t think about anything but that cock. 
       
       “Y-your hierarchy is fascinating, but…” Bill groaned, a small bit of reason poking through in spite of his submissive instinct. “I’m n-not quite sure I can handle something so intense right now… I-I’m already quite worn out and-”
       
       “Nido!” The king casually set the apologizing nidorino aside and turned his attention fully to Bill. “King!” The command was clear. The nidorino had warned him about it after all. If there was any doubt about what it meant, the king’s cock throbbing powerfully with need banished it from his mind. 
       
       “I-I am very sorry for sleeping on your g-grass. I didn’t know it was yours!” Bill tried to keep calm, but when the nidoking suddenly scooted him closer he couldn’t keep himself from giving way to yelling. He had to lift himself up a big to avoid his sensitive dick dragging too over the ground, and he was far too exhausted to keep any sort of balance. As a result, he ended up plowing straight into the king’s dick and landing back on his belly. 
       
       At that point, any chance of him talking his way out was gone. Between fear freezing his higher brain function and a submissive instinct kicking into overdrive, the king had him fully in his grip. “Nidoking.” Bill was reasonably certain it was a command again, but he didn’t know for sure. He didn’t care either. He just started licking out of desperation. Whether it was driven by fear or lust didn’t matter. 
       
       The king groaned in approval, and the nidorans and nidorinos around him chimed in his cheerful sounding barks of their own. Bill was momentarily distracted by the barks, curious about how strange it was for something as obviously dominant as a nidoking to require encouragement. Then he realized that the encouragement was for him. 
       
       The king’s dick had already been quite slick when he started licking at it, as if it had either been leaking for some time or licked beforehand. Bill found out why soon enough when the king slid his claws under his belly and hefted him up. Legs free from the ground, the pokemon began to panic. Soon he was face to face with the king, his hands sitting on the larger pokemon’s chest. The nidoking wasn’t planning to wait to claim him. He didn’t play around like the nidorino had. 
       
       “P-please, no…” Bill mumbled for a moment, still pleading with the king not to take him even as his tail twitched, and his dick throbbed. As far as he was concerned, he had learned enough for now, though the pokemon in him disagreed, and so did the king. 
       
       He responded only by giving Bill a lick, stunning him totally for a moment before lowering the nidorino harshly downward. 
       
       Bill wasn’t sure how much of the king actually penetrated him, though it certainly felt like he was given the bulk of the larger pokemon’s girth. However much it was proved to be enough to make him feel full to bursting, and he let out a very human scream as his virginity was taken. The king paused to let that yell settle, but only just long enough. After that he lifted his nidorino and plunged him down again, even deeper.
       
       Dominance was one thing, but Bill would never have thought he’d be controlled so thoroughly. He felt like less of a servant and more of a toy. Frustratingly, it felt right. It was exactly what he deserved for wandering into the king’s territory. The pokemon in him knew that fully, and it was satisfied with the way the king’s cock pierced deep into his belly. 
       
       Maybe one day he would earn the right to bow for the king or lift his rear for him, but right now he was an intruder, not a pack member. He couldn’t even earn respect through struggle, exhausted as he was. This was exactly where he belonged. 
       
       “N-nido! Nidorino!” He called out wildly as the king went on. Soon the giant was pistoning in and out of him. It was so hard he felt like he would burst. He couldn’t complain though, all he could do was scream and cum, which he did. And he did it again, again, and again throughout the session. The king didn’t care though. He kept pounding until the exhausted pokemon couldn’t take anymore, and perhaps beyond. 
       
       Bill couldn’t be sure, since he blacked out before it was done, exhausted. 
       
       What he did know was how sore he was when he woke up, used, dripping, still exhausted. It must have been hours later, since he could see the lights of morning pouring out from between the walls of the cave. 
       
       He didn’t have to question why he was cuddled up with a bunch of nidorinos and nidorans. Evidently, he had been accepted as some sort of probationary member. One of them greeted him with a cheerful, “Nido,” right when he woke. Bill was almost certain it was the one who had greeted him in the night actually.
       
       “G-good morning…” It was hard to speak, sore as he was, but he managed. The nidorino nuzzled him, happy for the response. 
       
       The king wasn’t there when he woke, but appeared soon after with food, blocking all light from the doorway. Bill knew to be scared, but he didn’t feel it. That same intimidating nidoking was almost gentle looking in the morning, arms full of berries. Every one of his pack approached him without hesitation. 
       
       And based on the urging from the other nidorino pushing at his cheek, Bill may have numbered in that pack now.
       
       He did hesitate to approach the berries, at first. It was his first day after all. Soon enough though, he would be proud to eat with his fellows. He’d find out he’d earned the right to bow before the king that night. 
       
       He still had a lot to learn about the hierarchies of the nido species of pokemon. And he would likely have a lot of time to learn too. It would be some time before he earned the respect necessary to even leave the cave after all.
