Interspecies potion solution (Monster musume Tg story) (Patreon)

“This suuuucks!!!” Miia complained, sitting in her room buried under a mountain of books that did not interest her in the slightest. “I might have gone overboard yesterday, but that is no reason for Mrs. Smith to lock me up in my room and study all of the do’s and don'ts of this whole interspecies thingy. I want to see my darling!”

“You called, Miia?” A young man opened the door and stepped into the room wearing his usual apron over his shirt like he was in househusband mode. Miia’s dull and lifeless eye immediately shone up by the sight of him. “I made some cookies to help you study. Do you want to try a few?”

“DARLING! You are my hero!” Miia shouted and sprang herself, using her snake-like tail like a spring, towards her darling, ready to tackle and embrace him and subsequently never letting go of him. “I really nee~...”

Bonk

“UGUGHA.!!!”

A loud yelp could be heard as Cerea, the centaur who always dashed her hopes, just as quickly stepped forward and swatted Miia out of the air with a mock sword, creating a painful yet oddly satisfying smack sound.

“You fool. Thou shall not touch my master until yee are done with thy tasks. And never with eyes tainted with indecency like the ones yee wore.” Cerea announced in her usual medieval way of talk, much to Miia’s dismay. Why must this damn horse always get in her way at the most crucial times?

Miia growled, glaring at the centauress for what she had done. She rubbed her noggin trying to ease the pain there.

“How can you not grant me this?!” Miia cried. “That is my darling you are talking about! He isn’t your master! He isn't your anything!”

She wanted nothing more than to make the damn horse pay for this. How dare she try and keep her separated from her destined one!

Miia moved like a serpent to her destined one. She called on all of her instincts to get past Centorea and reach her beloved. A smile blossomed at the idea of getting to hold her beloved Kimihito.

“If he isn’t mine Master, then he aint thou darling either. Now appreciate our master's hospitality and release him at once!” Cerea spoke and bonked Miia on the head a second time, making her recoil in shock and pain and release Kimihito from her coil. And from the sound of it, giving him the ability to breathe back as well.

“Auuuuu…” Miia quietly slithered back a bit towards her bed, watching her darling intently as he tried his best to stand up from the ground, still blue in his face from the lack of oxygen. Then he said, “Listen Miia. *cough* *cough* I know that Mrs Smith was pretty harsh to you by basically giving you house arrest until you study those books. But at the same time, she did show me a list with every rule you have broken since you came here and it was by far the longest out of all of you girls. So she probably deemed it a proper punishment.”

“*Sniff* *sniff* …why does Mrs. Smith have a list with my rule breaks? If my situation is so bad, then why didn’t she already send me home because of them?” Miia asked, making all three of them stop to think for a bit.

***

Mrs. Smith: “Listen. I am working overtime as is. I won’t bother pursuing every little misconduct of every person. That's just way too much of a hassle!”

***

All three of them frowned simultaneously as all of them just had the same thought about how Mrs. Smith would respond to that question. And of course the real reason why was because Mrs. Smith was, to the surprise of absolutely no one, too lazy to do anything.

“Anyways. We brought you some snacks.” Kimihito broke the silence and gave Miia a tray filled with cookies. She couldn’t help but blush at the kindness of his gesture, but he continued. “I believe that you can actually learn those rules in a reasonable amount of time. Feel free to join us downstairs once you are done with your share for today.”

And with those words, Kimihito and his annoying centaur bodyguard left Miia’s room, which caused her panic about those books on her bed to sink in again. But she needed to calm down. She needed to take a deep breath.

Mia took a deep breath as she shivered. Her temper boiled and she felt tears form in the corner of her eyes. Her eyes went to the books in the corner of the room and her anger spiked. Especially since she would be stuck in here until she had read all of them.

“Dawww!” Miia cried as she raged, pulling at her hair.

The more she looked at those books, the more reasons why she and her darling couldn’t be together. Every sentence on those damnable books was like a insult to her and her love for
Kimihito that she wanted to throw in a fireplace and then light a match so she would never have to see it again.

“This is unfair! Why can’t me and darling express our love like other people!” Miia raged.

Suddenly she recalled something that her mother had shared with her after she put the moves on her darling. A special thing that she had told her to use that would make it so when their relationship finally got to the point that she so desired would allow them to do what they pleased as much as they want. A grin came to her face and then a chuckle. Yes perhaps it was time to bring that out.

“Now… where did I put it…?” She asked, slithering through her room at top speed, making sure to check on all of her secret hiding places. But of course, she found it in the box she herself labeled with “Potentially dangerous stuff from mom.”.

Maybe she should have second thoughts about this before resorting to such drastic methods.

Then again, that damn horse was always stealing her darling and this ‘thing’ might be the solution to make her leave him alone once and for all. It might be a little bit evil, but that was something she was okay with. After all, it was normal for her to live up to being a cunning evil snake sometimes.

“Okay… I’ll do this!” Miia said, clenching something behind her in her hands and letting out a small giggle. “Fufufu~ And because I have read through the entire law, I know that this is entirely legal~ …at least if those last 4 pages don’t mention anything about this…”

And with that, she was off, out of her room on her way downstairs to see her dearest darling. And this time, she had a special present for him, to repay his generosity…

—

Hours passed and the rest of the girls and Kimihito did their routine around the house, cleaning up and making sure that everything was as it should be. With so many people living in one place, there was so much that needed to be done. They had devised a method on how they would go about it, making sure that Papi didn’t get too distracted, and that they were distracting Suu as well.

Kimihito looked up and frowned when he saw how much time had passed. It was always amazing how much time began to fly when you were occupied. He looked around the room a bit. Papi and Suu were playing video games on his big TV, Mero and Rachnera were talking about something by themselves by the dinner table, Lala was nowhere to be seen and Cerea was helping him a bit with the cleanup, since she was on duty today.

“Miia’s been pretty quiet don't you think?” Kimihito asked Cerea, with a hint of concern in his voice. As much as he would have liked to say that this was a good thing, he knew from first hand experience that Miia wasn’t a person to quietly give up on anything. Especially with how desperate she looked when he checked on her a while ago.

“Perhaps Miia has finally seen the error of her ways and is studying seriously,” the centaur remarked with a pleased smile, looking proud with her actions. And even though Kimihito really wasn’t a fan of using violence to solve problems, Cerea methods did seem to work on Miia when she lost herself in her lust.

“Maybe,” Kimihito answered sheepishly. As much as he wanted to believe that was the case, deep inside of him, he doubted it. Her studying quietly for so long was just something that he couldn’t quite see.

“Hello Darling~ You were talking about me?” Miia said, slithering down the stairs and surprising the two of them with a pleasant smile. She had her hands crossed behind her back and leaned forward to see what the two of them were doing.

“Oh, it was nothing important. How did your studies go?” Kimihito asked.

“Oh they went well,” Miia said as she slithered closer to her precious lover, trying to act as if there was nothing unusual about her plans. “I learned so much about the rules and the ins and outs that I might as well be a professional lawyer on them.”

“That is great to hear Miia,” Kimihito said, his voice having a tinge of pride and happiness in it for her. Though again his instinct told him that there was something off about the whole situation. The smile that she had seemed a little too happy.

“Oh darling it was nothing,” Miia said, trying to keep the smile that she had on her face. She felt a little guilty with how proud he seemed to be of her. Though she knew that the guilt would be gone when she finally got to enjoy her darling without worrying about the stupid law getting in the way.

But it held the possibility of ultimate success, so she had to try it.

There was a strange vibe in the air suddenly that Cerea picked up. She was obviously trained since she was very little in the way of the warrior, so picking up malice from those around her was a simple feat. Still though… malice in her master’s house?

Cerea took a step back and reached for the sword, scanning the entire surrounding for any potential assailants. Though there wasn't really anyone of note in the immediate vicinity. Just the usual subjects, like Rachnera doing some weird spinning tricks for Mero, Suu being kinda unpredictable, but occupied by Papi, and Miia who is… approaching Master with something hiding behind her back!?!

“Hold it, you foul creature!” Cerea shouted, drawing her sword and storming forward at the snake that was clearly about to harm her master.

“Eep~ Uff!!!” Miia let out a small yelp before Cerea tackled her and threw the snakey troublemaker to the ground. Cerea tried to pin her down, which was surely only possible because of her extra weight as a centaur, because there was no way a human could ever hope to restrain a lamia.

“Damn it all…” Miia let out, trying to struggle out of Cerea’s grip, but giving up shortly after as she noticed that it was pointless. “Why do you always get in my way…”

“What malignus plan were you about to enact on our master, you devious snake?!?” Cerea asked, making Miia turn away from her. Miia seemed seriously pissed off and didn't look like she was about to talk about anything anytime soon. So Cerea knew to press a bit harder, leaned more of her body weight onto the criminal snake and asked again. “What were you hiding behind your back?”

“Uhm… Cerea?” The voice of the master rang out behind her, though she had no time to turn around. “I think she was holding a glass with a drink.”

“What? How would thou bear the knowledge of this?” Cerea asked, making sure not to take the eyes of the grounded snake. Although, she looked just as confused by the master as Cerea was.

“Do you mind turning around real quick?” The master said, so she had no choice to briefly turn her eyes away from the evildoer.

Both Miia’s and Cerea’s faces took on an expression of disbelief as soon as their eyes fell onto Master. His face and shirt was completely drenched with him sporting a deadpan look on his face. On the floor below were traces of shattered glass as well, meaning there was a very real possibility that Miia was really just holding her drink a bit funny and Cerea had just tackled her to the ground and spilled Miia’s drink all over her master. Ooops.

“Uhm… Pardon there, Miia. I probably shouldn't have…” Cerea tried to apologize, but Miia interrupted.

“Yes. Yes. YES! Finally one thing that goes my way!” The evil snake girl celebrated and quickly slithered out from underneath Cerea, making her go into a battle ready stance once again.

“This was your ploy? What did you mean to accomplish, evil slitherer?” Cerea asked, pointing her sword at Miia, although she just laughed in return like an evil witch.

Kimihito meanwhile cleaned up the glass shards from the ground and washed his face off.

“This was a special potion brewed with a lamia’s secret formula. Now that his body came into contact with it, my bond with him will increase drastically, even if we are just standing in the same room together~” Miia laughed, making a single drop of sweat form on Cerea’s cheek. “It will go on until we have a bond so deep your little horse brain can’t even comprehend!”

“I won’t let a wretched witch like you win!” Cerea shouted, grabbed her master on his hand, forcefully sat him on her horseback and stormed out of the room. “I won’t even give you the opportunity to stand in the same room as him!”

“Get back here!” Miia cried. “You won’t stand in the way of true love!”

“Cerea! Slow down!” Kimihito cried desperately, thrown off by the sudden jerking as if he was a you being taken by two toddlers. “Ahh!”

Kimihito winced as his body suddenly started to feel hotter, despite the wetness from the concoction that was thrown all over him. He held the centaur tighter, worried that he would go sliding off if he let go of her. The young man blinked and pleaded, as the insane speed that his centaur ride was going at was threatening to throw him off.

The poor boy shuddered as if ice had been poured down his back. The young man gulped as he tried to get his bearings, trying to get into a comfortable riding position as he was sure that Cerea wasn’t about to let go of him that quickly. He adjusted his hold on the centaur girl as she stormed through his front door and out into the streets. Though holding his place suddenly became a lot more difficult, because for some reason his arms started to tingle.

“Ehh?” Kimihito blinked when he saw that the hair that was on his arms was gone. It was as if every little trace of hair that had been on his arms was gone. He rubbed his skin and was mystified by the softness that was there. If he didn’t know better then he would have thought that he was rubbing Cerea’s arms.

“Why is my skin so soft?” Kimihito muttered as he noticed that his legs felt even weirder than his arms did. For some reason, his legs and especially his feet felt weirdly bloated, like the shoes were getting smaller and more cramped by the second. It gave Kimihito a bad feeling about it. “Uhm… Cerea? I think something is weird, do you mind st…”

“Don’t you fret, my master! I will carry you to safety, where no foul snake or beast can harm you!” Cerea declared, causing Kimihito to be rather sure that she wasn’t listening to him at all. He just had to wait it out and make the best of it, and by now he was even in a proper riding position, so it wasn’t actually that bad riding her.

What was bad however was this almost itching feeling that started to spread all over his body, though mostly on his face. Kimihito winced as a sudden pain made him close his eyes. He shook his head, nuzzling against Cera’s back, making her shudder.

“Eep~ Master!” The centaur squeaked and almost lost her balance. “Please don’t do that!”

Kimihito didn’t respond, only managing to focus on his face as it let out low popping noises and felt like it was burning. It was as if someone was roughly tugging on his face, trying to stretch it out as hard as they could.

His nose let out a crack as it pointed a little further out, his nostrils getting smaller, while his lips puffed and swelled, letting out a pop as he sucked on them. It suddenly felt as if someone was roughly massaging his lower jaw. Just as quickly as it began, it passed.

“Owww,” Kimihito muttered. Despite himself, Kimihito reached up and ran his hand down his face and felt an unfamiliar structure. The height of the bones in there were off along with the curve of his jaw. If he didn’t know any better then he would have thought that he was touching somebody else's.

“Master! Hold on tight! I will get thou to safety!” Cerea said as she continued to gallop down the streets, seemingly still looking for a place to hide. Kimihito meanwhile had other problems, as the tingle had now officially moved down from his face to his neck and his shoulders.

There was this feeling of compression again, like his body was forcefully getting molded again. This time, his shoulders seemed to slowly get narrower while the entirety of his arms also seemed to get squeezed. It actually made it quite difficult for him to keep a solid grip on Cerea.

Despite the weird feeling all around he tried to take a look at what was happening to his hands and he was quite surprised when he saw. His hands looked small, dainty almost while his arms looked weird, but in a different way. While the hair that rested on them was completely shaken off by the bumpy ride most likely, his arms had gotten bigger and smaller at the same time.

Smaller in the sense that the literal size of his arms had decreased, but bigger since now he could not only see his biceps being straight very well, but it also seemed to get bigger by the second. Just what kind of drink did Miia spill on him?

The young man felt something off in his legs. it was as if the hair there was multiplying. His legs let out low pops and cracks as they moved on their own. The young man winced as they moved.

It was getting harder to move his toes. It was as if they were getting frozen or stuck in place. The feeling in his toes reduced until he hardly felt anything down there. They got more uncomfortable, and his feet felt like they were going to burst out of his shoes.

His feet broke through his shoes and the young man gasped at the sudden release. Kimihito looked down wondering why he was having such trouble with his body. His eyes immediately bulged.

“EHHHHHH!” Kimihito cried at the sight of hooves in place of human feet.

It only continued as his pants continued to tear and instead of human legs he saw black horse-like legs in their place. The ripping of his pants continued to travel upwards as his thighs ballooned in size, not only growing thicker but also expanding the sheer muscle mass in them.

He could literally watch his legs gaining a luscious curve as they kept filling up, giving him a more feminine appearance. By the time that they finished growing, he had huge womanly thighs that completely destroyed his pants and underwear, but that made it at least very comfortable to ride on horseback thanks to the extra cushion.

“C-Cerea!” Kimihito yelled, his voice sounding more hoarse than he would have liked. He could feel his Adam's Apple getting attacked by that tingling feeling, making the moans he let out get higher pitched every time he swallowed.

And then suddenly, it was completely gone. When he reached for his throat, there was no bump anymore, just silky smooth skin that felt completely out of place for him. It was as if he had just swallowed his Adam’s Apple, but at least the hoarse sensation was completely gone by now.

“Ahn! C-Cerea! Something weird is… Ah… happening to me! Please…” Kimihito let out in a sensual and very feminine voice, surprising even himself right after those words had left his mouth. But he pleaded again, in hope of snapping Cerea out of her galloping frenzy. “C-Cerea! P-Please!”

“I know! The hind side of the park shall be our safe haven! That slithering woman won't be able to reach us there with guarantee.” Cerea declared and picked up the pace, running even faster than she did before.

This told Kimihito two things. First, Cerea wasn’t listening to him at all anymore, though honestly he couldn't blame her too much since his voice sounded nothing like himself anymore. And second, Cerea had also become as crazy and focused on him like those girls usually do when they panic. Meaning, there wasn’t really any way for Kimihito to reasonably stop her, so he just needed to endure it.

Though enduring the ride might prove more difficult than he thought, because the weird tingling feeling suddenly started to appear all over his body again, making him involuntarily groan and moan. His body felt a whole lot more sensitive than it did before, making the not-so-calm ride on a centaur’s back feel a lot worse as her back repeatedly bumped against his most private place.

Kimihito wanted to readjust his seating on Cereas back again, but just as suddenly, a huge wave of nausea washed over him. It felt to him like his spine had suddenly become very soft and malleable, making him cling to Cereas waist with his arms for dear life, hoping not to fall off with her going at top speed. Not that she would let go of his hand around her waist anyways.

Then a bump in the road made Cerea jump a bit and send a jolt running through Kimihito’s body. It was like his manhood that still tried to hang on between his massive horse-like thighs got sent a little way into his body, causing a wave-like feeling to run upwards through his torso. This feeling made it feel like his spine and torso was getting longer as it traveled upwards and then finally shot into his chest, causing that to grow a bit as well.

And the worst part was, that this jolt now seemed to happen with every single hop, skip or jump Cerea did while galloping, which were quite many, to say the least. So Kimihito could feel his private member getting smaller and smaller between his massive hooved legs, while his upper body started to get so long that Kimihito started to get forced to sit upright so as to not fall off with his legs off Cerea on the backside.

And that is not even mentioning the fact that his chest, that was now definitely better described as breasts, had already surpassed the size of all other girls in his household besides Cerea herself. Seriously. They looked like Kimihito had stuffed two bowling balls under his shirt, and they were still growing.

“Ah~” Kimihito let out. He could feel it. His time as a man was over. With a few final bumps, he felt the remainder of his balls getting forced back into his body, opening up a fresh new slit in the place they had been. The new girl shed a single tear, before putting on a serious expression and deciding to try and stop Cerea finally.

“Uhg… My training is disappointing me…?” Cerea moaned. “My Master could never be too heavy for me! But…”

“Then how about you stop and see why I suddenly got so heavy?” Kimihito asked, pressing her breasts against Cerea’s back while making sure Cerea definitely noticed them. Though another weird feeling immediately spread through Kimihito again, making her cling on tightly to Cerea again.

It felt like his spine was forcefully bending while something tried to push itself out from the middle of his body. Granted, his torso was about three times as long as it was in the beginning, but that still didn’t make it any more pleasant.

Then she saw it, two bumps that appeared where her legs had previously been and continued to grow, looking almost as if they were two additional limbs sprouting out from Kimihitos body. Not just any limbs, but additional legs. With hooves at the end?

Oh. Kimihito finally realized what it was that he was turning into, making her feel stupid for not realizing it sooner.

“Cerea! I am turning into a centaur. You might want to stop and see this.” Kimihito said and patted Cerea on the head, making her whole body jolt a bit. Kimihito’s hopes were that this would finally snap Cerea out of her protecting and galloping frenzy, and it seemed like it worked.

Though by that point his additional legs had already grown to the size of his previous legs and were still getting bigger, but mostly just getting thicker and more muscular to match his hindlegs in appearance. Black fur had also sprouted all across his new legs, making Kimihito think that her transformation was about to come to a close soon.

Cerea started to slow down, having seemingly heard Kimihito’s plea finally, though a weird tingling feeling shot through his body one final time, but mostly in her torso area between her two pairs of legs. As she turned around she could glimpse her naked body getting covered by the same black fur that covered her legs in a hurry, before a stinging feeling hit right above her buttcheeks and a stream of even darker hair sprouted out from there to form a real pony tail.

And as the weird sensation completely left her body and Cerea managed to come to a halt in the middle of the somewhat far away park, Kimihito let out a sigh. It seems like she had really become a fully fledged centaur, and one that was only barely able to sit on Cerea’s back because of her new and improved size.

“M-Master…? Wh-What are thou saying…?” Cerea asked, shanking where she stood. It was clear that she was just as shocked as Kimihito, though Kimihito’s shock had mostly dissipated over the ride. So she tried her best to get of Cerea’s back, taking a few attempts before clumsily falling to the floor, causing Cerea to hop backwards and put her hands in front of her mouth in disbelief.

“Ouch…” Kimihito let out, briefly rubbing her head before giving her body another look. With her just lying on the floor, she had a perfect view over the entirety of her way larger body. From all four hooved legs, to her own horseback and even her honestly impressive ass and even her breasts, though those were probably just too big to ever be truly out of her sight.

“M-M-Master?!?” Cerea stuttered. Kimihito had never seen her so flustered before, so that was actually quite the amusing sight. After a short giggle, Kimihito gave her best to stand up, trying to get a feeling for moving all four of her legs at the same time. It was honestly way easier than she thought, but she still just managed to stand up very wobbly.

“Master! Let me assist you!” Cerea declared and walked towards Kimihito, giving the unsteady centaur a shoulder to lean on, which Kimihito really appreciated. Just having his feet touch the grass beneath through hooves was weird enough, having 4 of them was a bit much at once.

“Thanks Cerea. Let’s just hope you don’t expect me to run off with you now that I look like this… hahaha.” Kimihito let out weakly, though Cerea didn’t seem like she was in the mood for jokes.

“What happened to you, Master? How have thou changed into one of my kind? And how are you…” Cerea stopped for a moment as her face became bright red like a tomato. “How did you become so… attractive…?”

“Huh? Attractive?” Kimihito asked, making sure she had heard Cerea correctly.

“Yes. I have never been one to like the appearance of others of my kind, though you… despite being a girl… You look… very…” Cerea was getting flustered so hard that even her ears started to glow bright pink, causing Kimihito to let out a small giggle.

“I am glad that my appearance is at least candy to your eyes. Hehe.” She giggled, making Cerea actively look away from her. Had Kimihito really become that hot that even the usually calm Cerea could no longer look at her.

“Excuse me, my ladies.” A young police officer said, seemingly approaching the two centaurs out of nowhere. He looked a bit flustered as well, though then just scratched the back of his head and said. “I saw you two riding on top of each other, and it was just something I never thought I would ever see. If you don’t mind me asking, do centaurs usually ride each other like a human would ride them?”

Cerea looked flabbergasted by the whole situation and didn’t seem to be capable of producing any meaningful sentences at the moment, so Kimihito knew she had to step in and give an explanation. Even if it was a lie, the most important thing was that the two of them got an explanation for their actions.

“Not really. But Cerea and I regularly train with each other and this is just one of the more fun methods we choose to improve our strength. After all, if we can carry a centaur without problems, then carrying around our master shouldn’t be anything but child’s play, right?” Kimihito winked at the police officer, who nodded understandingly.

“Yes, that makes sense. After all, a centaur is way heavier than…” The police officer quickly covered his mouth, before he could speak any further. Kimihito didn't quite get it at first, but then let out a pained laugh. The police officer tried to correct himself. “I mean… uhm… That was inappropriate. I am sorry. It… Uh… definitely seems like good training.”

“No need to sweat the small stuff.” Kimihito said, trying her best to give the officer an honest smile. “Even on our best days, both of us are about five times heavier than our master could ever be. It’s just our physique, nothing we can do about it.”

“Yeah. Speaking of which, may I ask where your host family is?” The police officer asked, making Kimihito start to sweat a bit. Yup, that was a question those police officers liked to ask, and now she needed a damn good answer for it. And then she remembered.

“Ah yeah. Uhm, sorry about that. As you can see my pa…skirt kinda ripped on our way here. We have a special permission pass from the MON agency and are allowed to train outside without a host. I just now realized that my pass was in my skirt…” Kimihito answered, then slowly turned towards Cerea who just blinked at her wide eyed. “Cerea, you still have your pass on you, right? Mind showing it to the officer? I promise I have one too, but… you know…”

“Huh? Ah, naturally.” Cerea fumbled a bit, but seemingly finally snapped out of her stupor and clumsily frisked her own pockets, until she held a certain blue ID card in hand. And without any hesitation, she showed it to the officer, who seemingly also immediately recognized what that card was.

“Ah, I understand. Your name is Centorea Shianus then? Yes, special permission by the cultural insterspecias exchange program to train outside without a host.” The officer nodded and waved his hand. “Ah yes, okay I believe you girls. But if I were you I would probably make sure to go home soon and get dressed. For centaurs it might be okay to run around without wearing anything on the bottom half, but it's rather frowned upon in human society.”

“Ahaha…” Kimihito let out while cerea started to heavily blush. Kimihito’s first instinct after the comment was to cover her privates, though she realized quickly enough that there were no privates between her front legs anymore, which felt kind of weird. “Yes, we will make sure to go home soon then. Thank you for your advice.”

The officer just nodded, raised his hand as he turned around and excused himself. The moment the officer was out of sight, Kimihito fell to her knees, to all four of them, making her massive boobs jiggle way too much for her liking. Maybe she really needed to wear a bra starting now.

“M-Master!” Cerea yelp, unsure of what had just happened.

“Trying to lie to an officer while struggling to stand in a way that I have never done before… Yeah, that just took a lot out of me.” Kimihito answered with a pained smile while Cerea still panicked. Then Kimihito let out a sign and said, “Listen up, Cerea. I need your help right now. I am not sure how smart it would be for me to ride you back home, so you need to help me quickly learn to walk as a centaur.”

Cerea's panicked state seemed to finally subside, as she took on a more composed stance towards Kimihito. “I understand, Master. I will help you in any way I am capable of.”

Together, the two of them managed to raise Kimihito back onto her four hooved feet again, and started to walk slowly towards their home. Though, to the surprise of Kimihito herself, walking on four legs proved to be surprisingly similar to what he was used to anyway. So their way home quickly didn't look as impossible anymore as Kimihito had first thought.

“When we get home, I am immediately calling Mrs. Smith if you don’t mind.” Kimihito announced, making Cerea nod along. But then she added. “I have heard that centaurs only really care about clothes up top, and not really down below. Even going as far as calling them annoying and unnecessary, but I never see you complaining about them or even ever not wearing clothes on your whole body. So is that rumor true?”

“Uhm… sort of…?” Cerea answered, her face starting to blush again. “If my memory serves, then my proud race of centaurs had always been warriors and therefore mostly wore armor in the past. But in peaceful times, our race adapts to the fashion of humans. So we usually see to it that humans don't see us half naked.”

“So I should quickly find something to put onto my massive behind? Because for some reason it really doesn’t bother me that much since fur is covering most of it.” Kimihito laughed.

“It would be advantageous.” Cerea blushed and averted her gaze once again, making the walk home even more awkward.

—

“Yup, definitely Mirror-gänger elixir.” The dark-skinned woman with the long white hair and way to few clothes on said, as she gave the few shards of glass back to Mrs. Smith, who just nodded. She took one deep breath, and then looked at the two centaurs, the shame kneeling Miia and the rest of the extra-species homestays from Kimihito’s household.

“Thanks Doppel. Alright, I got some good news and some bad news for you then.” She said, making the ears of everyone present perk up. Though because Kimihito already knew exactly that the bad news was probably the more important information, she let out a defeated laugh.

“The good news is that we know the cause of this situation. Our dearest Lamia here threw a concoction onto you, darling, that is traditionally used by Doppelgangers and Lamias to hide humans they kidnapped in their ranks, without anyone being able to find them. The exact effects it is capable of afflicting are complicated, but basically it turns the victim into a sort of twin sister of the extra-species person closest to them.” Mrs. Smith explained, with the doppelganger agent behind her nodding along.

“Wait! So me and Cerea are now related?” Kimihito asked wide eyed, making Cerea blush and blink rapidly without bringing out a word.

“No, not blood-related in that way. That would defeat the purpose of what the potion was used for after all. More like her physical attributes got copied onto you. Like hip size, breast size, height, muscle mass, all of that stuff.” Mrs. Smith explained further, but then gave off a sigh. “It’s basically: What if you were still yourself, but suddenly got almost all physical attributes of Cerea out of the blue. Does that make sense?”

“The potion basically works with the same principle that we doppelgangers use to change our forms.” Doppel-chan said, making her white hair cover her whole body suddenly and making her grow in size and change her features, until she looked like an exact copy of Kimihito in her centaur form.

“That is amazing! Though why did Miia have this with her?” Kimihito asked and turned to face the still somewhat sulking Lamia next to her.

“I got it from my Mom as a last resort to get closer to my darling. I didn’t know what it would do… I promise…” Miia cried, but stopped and stared in shock as Kimihito started to pat her head. It didn’t take long for her to shed the sad face completely and nuzzle her head into Kimihito’s patting hand.

“Okay, now onto the not-so-great news.” Smith continued, sitting down on a chair and taking a sip from her coffee before continuing. “The Mirror-gänger elixir is notoriously difficult to reverse, mostly due to the fact that our science doesn’t quite know how Doppelganger shapeshifting works, and therefore there is currently no known way to artificially stop its effects.”

“Great.” Kimihito spoke with a deadpan look on his face, while every girl behind her started to panic.

“Now hold on, before you complain too much.” Mrs. Smith stopped all the girls before they could rampage too much. “The elixir is only known to last for a limited amount of time. And while we can’t really say how long it will last or have any way of accelerating it, we do know that the effects will wear off eventually.”

“How long are we talking about?” Kimhito asked hesitantly.

“Doppel-chan?” Mrs. Smith turned to the shapeshifter.

“This was some powerful stuff. Probably over a month for sure. And there was also something else inside of that mixture.” Doppel said, taking the glass shard again and licking the content briefly while turning her body back to her usual form. “But I can’t point my finger on what it was…”

“Welp, then we better give you a new ID for the time being.” Mrs. Smith said, shrugging her shoulders. “Starting today, you are Kirika Kurusu, a centaur with full permissions from the MON to act live and move freely through the cities. I’ll go and print your ID card when I get home.”

“Great… But it could honestly be worse.” The newly named Kirika exclaimed and shook her head. “But what was that about that extra thing in the potion?”

“Oh that? I have no idea what exactly that was, but it does make you look very sexy in my eyes~” Doppel-chan said, smacking her lips as she did. “I would probably say that they added something that makes you super attractive to us extra-species, though not sure how they did that. So you probably want to avoid touching extra-species a bit, if you don’t want them to fawn over you~”

Kirika blinked briefly and looked down her arm to Miia who she was still happily head patting. She let go for a second only for Miia to open her eyes and give her a very hungry and blushing look.

“Welp, our job here is done~” Smith declared, grabbed by the hand and dragged her out of the room. “I can’t have you seduce my fellow agents after all, so we'll be taking a leave. I’ll have your ID ready by tomorrow. See ya~”

The door closed, and Kirika immediately shuddered as she felt the gaze of a lot of people on her suddenly. Miia, Rachnera, Mero and even Cerea were looking at her, everyone with a different look on their face, but a look of lust nonetheless.

“Hey, guys… can we talk about this…?” Kirika tried to say, though those four only went a step closer to her in response.

And just like that, Kirika was caught in the middle of an extra-species struggle once again. It seems like even gaining hooves, massive boobs and a pair of extra legs wasn’t enough to make those girls not fight for her. At least she was a faster runner now… when she finally got the hang of her additional limbs that was.

---

Enough is enough. Miia knew that if she didn't act now, she would probably never get her darling. Though was using the potion of her mother really such a good idea?
