________________________________________________________

Many times things beyond people’s control can and will happen. Tea and Yugi are no strangers to such happenings. Be it souls taken from friends or people taking over other people’s bodies. Strange oddities occur in the world, magical and with sometimes no clear logic.

Da’dum, da’dum, da’dum

Tea’s hooves clack against the back-alley streets of Domino City. For all the magical oddities she never had expected to have the behind of a horse, her torso though still human. From below her waist, she was a full horse, with four hooves and a tail. Trotting along the streets with little Yugi on her back, the only thing her mind could focus on was trying to get some help out of her situation. Kiba Crop was sadly the only place she and Yugi could think of that would even possibly be willing. The city would probably go into a panic if they saw a random centaur woman galloping down the street. At the very least with the transformation, Tea felt stronger. Her arms have a bit more muscle than once before. Her clothes to her dismay are currently some type of armor though. The armor she could certainly do without, it felt awkward and stiff against her skin, some sort of chainmail lining under it to try and ease the bulky weight. “Yugi…” Tea poses her words carefully as they leave her lips. She still feels her nerves rattling. They won the duel sure, but if she stayed in a body like this, her career as a dancer would not exactly work. “I um…” Thinking the thoughts her words grow shaky. “Y-you think… you think this will go over well? I mean we all know how Kiba can be.”

Approaching closer to the large corporate building Yugi’s grip against Tea tightens. “Well…” He could not but be nervous in the same way Tea was however, his nerves were stuck on even letting a situation like this happen to one of his friends. “We have to just hope it will work. The people in the city would probably react badly if we just walked around like normal. Or at best they’ll think you’re some sort of mascot. Kiba Corp right now is the only real place we can go that might have something to help us.”

The words do little to ease Tea’s mind, though she knew not much would ease her in this situation. Trotting up to the back entrance of the building Yugi looks at the guards standing outside. Kiba and Yugi were, on some sort of terms with each other. Though the relationship was not exactly friendly. Hopping off Tea’s back he walks to the guards and begins speaking leaving Tea to speak to herself. “I wonder how I’ll even sleep…” Mumbling under her breath Tea trots in place listening to her hooves clack against the cement ground. “Mokuba would probably be the only one even willing to hear us out… Ugh, horses sleep standing, don’t they? I don’t even know… maybe I could lay on my side?” One thought, then another, Tea’s mind keeps sorting through different topics trying to make herself less nervous. She only makes herself even more nervous. “That guy really had to change my body… he should have at least turned me back when the duel ended.” With a huff, Tea points her nose up and sighs through gritted teeth. “The sore loser.”

“Tea!” Yugi calls out running back, a smirk on his face made it seem like things were not going badly at least. “They said we could go in!” A little excitement fills Yugi’s voice, clearly happy being able to help. Still, Tea’s nervousness was showing. To try and reassure her Yugi awkwardly hops in place at first trying to reach Tea’s hand. Seeing it as a fruitless effort he sighs and pats at her exposed fur. “It’ll be alright Tea… We’ll make sure to figure something out. Mokuba said we could come in… but apparently, even Seto is curious about this. I don’t know exactly how things will go. But… if you can stay here for a bit, I’ll at least try and make my way to Egypt to see if I can find some sort of magic to help.”

All the words were not exactly reassuring for Tea but she nods regardless and starts walking with Yugi. The back entrance has a garage opening which is easy enough for Tea to walk through. Already entering the building is met with all sorts of prying eyes. Scientists getting materials, other guards, janitors, and all eyes land on Tea’s centaur body. The body is something out of a fantasy game or book, though before them all it was now real. Tea tries to lower her head and keep walking. One of the scientists seemingly waiting for them nervously begins writing on a tablet with a stylus their eyes going back and forth between Tea and the tablet. “Well—” The scientist mutters out his words blinks a few times and tries his best to keep composed. “For… for the time being, I will be guiding you to our animal research division. We already happen to have horses and stallions, and ponys, on hand. Donkey’s and Mules as well… the point being, yes, the point being we have stables in which she may rest. Do not worry though!” The scientist begins moving his hand waving back to Yugi and Tea to follow. “We understand your companion here is still human. Her upper half is still exactly like that of a human, if her organs have moved at all would be curious… Yes… not to get off the topic of course. Yes, I wanted to add we will make sure her accommodations are still civil. We are not just going to give her a stable filled with just hay and tell her to make due—if that is a concern.”

Tea groans her hooves trotting along. “I wasn’t worrying about that…” Now her thoughts could only worry about it. The scientist seemed far too intrigued by her. Not that she could exactly blame him, a fantasy creature appearing in front of someone would be interesting or scary or both to plenty. “I don’t know what you know about my situation.” Tea swallows back spit and breathes out slowly, she may as well try and explain things a little, Yugi probably did not give all the details to the guards. “I only became like this a few hours ago. I don’t know if you’ll need to check me or something… but my legs are gone now. And I just have these… horse hooves now. Six limbs. And… this all feels plenty weird. I just wanna figure out how to turn back.”

The scientist begins taking more notes on his tablet nodding slowly as they walk through a series of metal hallways. “Yes, six limbs, and you can move all of them independently. Only just getting the body you can also move the hooves normally…”

Sighing Tea seemed to not be helping matters much. Keeping her mouth shut for the time she and Yugi keep following the man till they begin to hear a cacophony of animals. The metal halls echo with the noise, unsettling as it was the trio keeps moving. It takes another five minutes but they finally reach what the scientist called the stables. The room has a door and entering it; Yugi and Tea are greeted to a much larger room than expected. The ceiling goes up about twenty feet and the room itself appeared longer and wider than a yard. The center of the room is a mix of grass and metal pathways. It appeared the room served as some sort of small contained grazing pasture for the four-legged animals. The area even has a pond where two horses currently drink from. Rather than a sky above a holographic projector sits activated. Like duel disks use to create field spells the projectors currently emulate a fake sky, sun, and moon to simulate the current time of day outside. “Wow…” Tea’s jaw drops, unsure how to express the amazing sight before her. She figured to see more blunt animal cruelty. This sort of sight was like nothing she could have thought up. “This place is giant… it even has a pond! What sort of animal research is even being done here? Why would you need so many animals and some place this big? Are the other halls we passed… do they also have giant rooms like this? It’s like some underground zoo.”

The scientist’s eyes shift between his tablet and the two behind him. “Yes… Mr. Kiba!” Blurting out his words quickly the man stiffens in place and straightens up like in some sort of military force. Seto Kiba though was a rather intimidating man so the action did not surprise Yugi or Tea. He walks with his brother over to the group his eyes glancing over Tea’s body quickly and then at the researcher waiting for a response. “Sir.” The scientist stutters more nervously than before his hands shaking a little against his tablet. “Preparations have been made, the data is being uploaded, and the room has been prepared as asked by the floor staff!”

Seto gives a quick nod, as usual, his eyes are sharp, his height tall and his long jacket collar is pointed and up. “Yugi.” Seto’s voice as usual sounded snobby, all knowing like he was better than everyone else. “I don’t care about your little friend’s new problem. You can thank Mokuba for insisting. Of course, he also gave me a good idea.” Seto turns away from Tea now acting like she was not even there or mattered to his plans. His eyes focus on Yugi only. “If you insist on keeping your friend here. You’ll help me bring him back. The puzzle has only ever responded to you.”

Tea could tell by Yugi’s face he wanted to groan. It seemed like he knew something like this was going to happen. Yugi however, grits his teeth and nods at Seto. “Fine. Just make sure Tea’s taken care of.” This time Yugi speaks looking at Mokuba instead of looking at Seto.

Looking eye level with Yugi the nicer of the Kiba brothers gives a nod back. “Of course, Yugi. You can count on me, but if I’m going to, you gotta give Seto here what he’s looking for too. Alright?”

Some agreement had been made and Tea was not even a part of it, even if she was the cause. She sighs and trots back a bit her hooves pressing into the grass. It did feel nicer than standing on metal, to say the least. “I wonder what I should even do now.”

Mokuba’s ears perk up and he twists around running over to Tea’s side. “Oh Tea, here!” Mokuba throws a keycard up in the air and Tea catches it in her hand. “That keycard will open up the room we prepared for you. It’ll be off on side B, the thirty-fourth one, the rooms and numbered and label so you’ll find it. The panel to swipe the card will be level with where your arms are currently don’t worry. We’ll send some messages to ask more about the situation for what you can tell us. But for the most part, just try and relax. Read or something. We left a computer in the room, as well as some different clothes that’ll fit over your top half at least. It is night time so a lot of our team is heading home for the night. We do have a lot that stay through the night though… if you have questions, we have an intercom in the room you can use.” Mokuba nods slowly to himself gears turning in his head to make sure he covered all the info. “Oh yeah, we have food in there as well for you, so don’t worry over that. Just while you stay here try and not bother the other animals that much alright? We wouldn’t want them to get irritated by you. Or any other weird reaction, try and keep your distance. It’s best if you stay in your room, least till morning.”

Yugi gives a nod toward Tea, and she nods back. They had to separate now. Seto and Yugi walk away, then Mokuba and the scientist also go their way. Tea was alone, beyond the animals filling the room. Clutching the keycard in her hand she trots over to the side of the room labeled B and starts walking past the different numbers. Room thirty-four is a bit away but Tea has no trouble finding it. Swiping her card in the card slot the room's latch turns green and slides open.

Tea enters the room taking in the design of the place. To start the room is rather wide and large. To her it was a bit unexpected, hearing all the talk of stables she figured it would still be a box. Though square in shape, it was not cramped. Tea can move her arms freely, stretch, and even turn around without hitting anything. In her mind, it was as big as a master bedroom or living room if it could compare to anything. The room itself is bigger than her actual bedroom. Scoffing under her breath she trots herself over to the fridge that was placed inside the wall to save further space. “Tsk, leave it to some rich place to make the stables even impressive… these walls to have everything huh?” The fridge holds a few different drinks in them. Tea grabs a simple iced tea and cracks open the can sipping gingerly at it. Trotting to another wall she runs her hand along its side. She could feel all the indents running across it, like imprints of different objects. “I’m not good with this stuff… do the walls move or something? I guess that would explain how they got it ready so fast.” The wall with the door just had the door, to the left the bare indented wall, forward the fridge and with-it shelves making some sort of cooking area with even a sink. The right side has what is supposed to act as a bed for Tea, which currently is some sort of hay bundled in cloth. A little in front of the bed more toward the kitchen area is a large button reading bathroom. “Uck…” Tea groans and sets her drink down against one of the kitchen shelves. “I really hope I don’t have to worry about using the bathroom like this… but what are the chances any of this gets fixed that quickly?” Tea had already eaten at the very least, so she trots over to the bedding her hooves sinking into the softness. “So… how do I do this…” Sighing Tea starts by closing her eyes, feeling her legs wobbling a bit. “Horses don’t really stand up to sleep, do they… I think… I think I’ve seen cows bend down?” Trying to recall images from school Tea carefully presses her front hooves against the bedding and lowers her back legs down folding them up. It seemed to work well enough so she bends her front hooves in kind letting them rest against the soft bedding. “There… this is a bit better, but…” Tea blinks a few times looking down at herself. Her horse half was indeed laying now, but her upper torso, her head, she had nothing to lay against. At the very least she had some time now. Slowly she takes off the pieces of armor that had been clamped onto her. She did not need armor or great axes. The process took a while, but with some idea of how to lay down, she gets back up to at least throw a white t-shirt over herself to cover her torso. Settling back down on the bed,  Tea could tell it still would be hard to get real sleep. Awkwardly she gets closer to the wall and leans herself against it. Sighing her eyes stare off getting heavier with each small breath. “I’ll just have to trust in Yugi… or start getting adjusted to this body.”

Hours tick away, and the night looms on and on. The subtle sounds of hooves, the rustling of hay from slumbering steeds. The noises, the foreign sounds, the odd positioning. Tea feels a constant state of terribleness looming over here. Her eyes feel heavy trying to sleep yet being unable. She probably got at least an hour but it was mostly from dozing off from exhaustion. Standing up from her bedding Tea walks to her door and opens it taking a step back into the grazing area. Stepping out her hooves feel better against the grass. Walking and walking she takes in the fake night sky. Even if fake it still looked pleasant, a starry sky looking down at her. If she could dance in her current form she probably would.

CLANG

The door to Tea’s room shuts and her body shivers. “Wait—” Galloping back over to the door Tea presses her hand against it, but nothing. Patting at her shirt her face twitches into a regretful appearance. “I… I forgot the card with that armor. I left it on top of the pile I made.” Tea sighs deeply looking out across the grazing field. A few animals were still up, maybe other ones that could not sleep as well? Many others were in more normal stables. Tea could see plenty laying in actual hay or standing around like it was fine. “Great… they didn’t say what I’m supposed to do if I lock myself out.” Groaning under her breath Tea starts trotting on toward the pond. “Probably because they didn’t think anyone would lock themselves out…”

Sniff, sniff

A scent hits Tea’s nose. It makes her body fidget, her nose twitch, and her eyes wince. “Wha—” A loss of words prattle off her lips. The scent is somehow intoxicating. Her horse half quivers in its presence. Tea had not noticed when first walking around but the stallions were all rather large. Their stables were right next to the pond. It was not her intention to stare at them, they were animals, and piles of filth were in their stalls. Even if the researchers made sure to keep things cleaned, for the most part, they were still animals. “Why…” Tea’s eyes cared not for the filth though, they zoom across the horse landing right on the crotch. It was not like she was some depraved pervert. The scent simply drew her closer and made her eyes focus. The sheath, the erect cock hanging out, the long pink shaft, and the black head. Tea’s cheeks start to turn red the longer she looks. “Stallions… stallions… that word isn’t just another word for horse. It. It means they're male or—” It meant the horse had not been castrated, it still had its instinct to find a mate and breed offspring. This brown horse with black braided mane flutters its lips and shakes its head eyes looking right at Tea. “It… it um, I guess I hadn’t seen many…” Tea’s eyes break contact with the stallion looking at some of the different stables now. It does not take long to notice that none of the stables say female horses are held in the area. “It got excited cause I look like a female horse?” Tea carefully trots on over to the stallion's stable and reaches her hand toward the stallion. “I-I um… calm down?”

SNORT

The stallion knocks Tea’s hand and kicks itself up with its front hooves. Pressing against the metal stable door the stallion looks over Tea’s head its lower half fully exposing itself to her from the barred stable gate. “H-hey!” Tea covers her eyes looking away. “G-geez… what’s a girl got to do to not get flashed around here? It… it has those… balls too? I never really seen this much before.” Tea peers over her shoulder and then back toward the snorting fussy stallion. Her heart starts to beat as she sniffs at the air again. Her hooves lower like how she tried to sleep before. Now she is level with it. The stallion huffs again and waddles its hind hooves forward so the long horse cock wags in front of the stable gate. Tea reaches forward, and her smooth human hands touch the ruff cock gliding against it to feel the stiffness it has. She even leans into the bars of the stable gate just to cup her hand around the heavy ball sack of the horse. “G-Gosh… o-only a stallion would be built like this.” Tea could not put her finger on it, yet she literally was. Both her hands were now through the bars wrapping around the long shaft of the horse. She had no idea what was compelling her, curiosity? Maybe her new body was just reacting to the pheromones in the air? Regardless, she starts to rub her hands against it. Stroking and stroking away. “M-mm…” As Tea keeps it up she tries to not listen to the snorts of the stallion. Her body keeps quivering, her lips keep passing small moans. She is getting turned on and she just cannot understand the feeling. The more she strokes the cock the more it flexes in her hand. The more she strokes at it the faster it begins to dribble with cum. The cock is long and almost curved, probably to properly get under a female horse. Thinking the thought Tea could not help but notice her folds were getting wet. Her heart rate goes up more, her breath starts to putter out quicker. “Wh-what am I doing?!”

SPLAT

The stallion was held back from this sort of activity. Having someone masturbate it with soft human hands also seemed to help. Thick blobs of cum shoot from the stallion's cock covering Tea’s arms with the globs of liquid. It even hits against the stable gate. Normally it probably would have shot against her if the gate did not block her. “E-ew…” Tea mumbles softly but still keeps panting as she slowly pulls her hands away from the bars. “Is… do they always have so much?” Tea looks at her coated arms doing her best to wipe off the ripe spunk onto the grass. “Th-this is so thick too, g-gross….” Her breath starts to get faster, and despite her words, something about the whole situation is still so exciting. Lifting her left arm close to her face, she licks at the cum her body shivering at the taste of the odd liquid. Swallowing it down she can feel the small amount she had licked start to get caught in her throat. Even so, her face keeps red, her mouth still panting, her body still quivering with desire. “Wh-why i-it’s… it really is gross. Isn’t it?”

Tea tries to get off her feet but feels fur against her back. A few more stallions had now begun to surround her. They came from their own open stables. The one in front of her may have been locked up for the night, the others however were not, and after seeing the display they were eager themselves. Some of them snort and shake their heads, Tea could not move away. Three horses in the back and one in front of her behind a stable gate. Tea already was seated and the stallion atop her was not exactly letting her stand back up. She could smell them too, that same scent of desire the other drew her in with. The stink of a throbbing stallion cock. She was unsure how her horse half would react to such things, but the stallions did not care, she could feel the one over her pressing against her making her feel the throbbing cock against her backside. It wanted her to stand so it could press into her, get under her and penetrate. The others wanted part of the enjoyment as well, maybe to use her after the first was done, or maybe they just wanted to blow their load and did not care if they just got a handy out of it.

Tea’s hooved legs quiver, what was it about the situation that stimulated her so? She starts panting more, she could escape if she really wanted to, could she not? Her back grazes against the chest of the hairy stallion. “Nyyeah!” The stallion leaps up on its front hooves just like the first had. It too uses the stable gate to balance, only this time it has Tea right under it unlike the first. The stallion has no words but makes sure to grunt and snort more. Tea was as ready as she could be. Her forehead sweats, and her body quivers, but she feels far too stimulated to just stop. Her horse half is a horse anyway, what exactly did she need to justify?

Plap, plap, plap

The stallion does not ask for confirmation from Tea, does not wait for her to brace, it simply shoves its cock into her, balls slapping against her. “U-urck!” Tea groans out in pain, the stallion's erect cock presses her insides and forces her open. Her legs almost buckle down but just barely manage to stay in a half squat. Tears start to well in her eyes straight away, but she does feel pleasure among the pain. Her body jerks against the stable gate, forcing her normal human hands to do their best to keep her braced against it. Her body however keeps pushing into the bars with the strength of the stallion beating into her folds. “N-nngh arrgh!” Groaning, moaning, spit drips off of Tea’s mouth. Her heart keeps pounding, her breath keeps panting. Her horse half starts to sway and shake trying to work with the stallion just so she could get fucked easier. The pain keeps her mind sharp, the pleasure makes her unable to focus on anything but the cock pounding into her. It was just a dumb stallion, animals do not do this sort of thing for fun, she could feel its cock flexing already in her. How was she even supposed to refer to her horse's insides? It was still a vagina, so she does her best to clamp down around the cock. Tea wanted it making it clear by tightening her grip against it. The stallion had been kept from women for who knows how long, she was the first female it had seen in a while most likely. The stallion cannot help but release. It cums, it cums filling up Tea’s insides. Her legs buckle down for real now the horse pushing off the gate to back away. Tea could still feel it though, her insides gaped wide and now dripping with the stallions spunk. “A-ah….a-agh…” Just trying to control her breath feels hard, did she even reach her orgasm? It was hard for her to say not being used to the body. What if the stallion actually was able to get her pregnant in her current state?

“Naay!” Another stallion blows air pasts its lips. It gave Tea no time to think over her situation. It was simply an animal, after all, an animal that had no outlet. It did not care about who used her or what she did, it just cared about what she had to offer. The stallion mounts itself over Tea’s body without warning. It presses its hooves against the gate now. It was almost like a routine that had been studied since the group of stallions watched it twice now. The third stallion wanted to make his impression. Tea weakly grips at the bars of the gate and turns her head to the creature snorting out hot air from its nose. She barely knew what to say, she should probably stop now, go back to the door, and explain how she got locked out.

Plap, plap, plap

Tea has no time to recover or choose, she locked herself into her situation already. Another stallion’s cock pounds into her backside. Using her ass this time. Maybe it has no interest in getting its cock stained by another male's cum. Regardless it seems far more aggressive than the last stallion. It humps against Tea’s ass faster and faster. Tea is barely getting any time to process at all. She feels her ass bleeding, the pain pulsing through her body. Her hands feel like they might rip the bars off the stable from how fast the stallion pumps its cock back and forth into her. Is penetrating always suppose to be so rough? “R-rgh!” Tea coughs up spit against the bars. Her forearm quickly wipes away some tears from her eyes. This one too cums filling her ass now with stallion spunk. Tea groans to the warm feeling. She can feel cum dripping down her hooved legs, she can feel the warmth of the cum in her insides. The third horse does the same as the second then dismounts her and trots off like nothing had happened. “Mmm…” Tea moans softly, her cheek pressing against the side of the stable gate. The fourth stallion still never got its turn.

“Day has Begun”

A computerized voice speaks over an intercom.  Tea only hears it because it wakes her up. Her body feels sore and sticky. Her top is barely holding on, the white t-shirt looks like it has been ripped in several places exposing Tea’s skin. The fake sun shines down on her all the same. The stables around her are all open releasing other animals from their pens. “O-oh no…” Groaning with a low voice Tea mumbles out her words but her throat feels warm and sore still. Slowly her hooved feet press her off the ground. She is still by the locked stable gate the stallion she had first dealt with is still inside. “Did that all really…:” Tea’s legs quiver again, and her eyes look back at the crowd of animals slowly walking by and glaring at her. She can still feel it, the cum the other stallions filled into her. Her memory after blank, what happened with the fourth one, did other animals use her without even realizing it? “I… I-I need to go.” Tea bites at her lip feeling shame wash over her. She let it all happen and enjoyed it to some degree. Walking slowly toward the entrance of the grazing area she sees Yugi standing by the door talking with Mokuba. “H-how… how do I even start to explain this?” With each step she takes Tea can smell the scent, on her clothes, in her hair, her insides. Turning back into her normal human form was supposed to be her objective. Her lingering mind trots on forward, unsure if she ever really can go back.
