(M tf Cow-mutant)

The Arcane University had a rough few years- its previous management dropped the ball on magical regulations and several commoners got themselves into heaps of problems that snowballed into a situation that almost leveled the city. With its reputation very slowly crawling back to where it had been, the university took interest in, and started a research project around one of these sort-of mishaps.

Though this situation did spiral out of control- the initial creation was actually a resounding success and an interesting delve into combined arts. The Farlane sisters used both alchemy and magic together to create a topical potion that would imbue traits of an animal temporarily to someone- they had used this to induce extreme lactation in themselves to hold up their ranch. That part worked perfectly. Unfortunately this also resulted in one of the sisters unintentionally giving birth to a daughter who was cow... and then forcing the sisters to create a version of the potion that did the opposite of the original- to turn their cow-daughter into a human.

Then things really went out of hand when they made the mistake of relying on a poorly informed friend to dispose of some old equipment they did not need... which resulted in her getting some of their potion on her. The problem there is by that time the potion had well exceeded its expiration date and its effects were wildly chaotic- creating a bovine abomination rather than a cow. While under the effects however- her bodily fluids transferred the chaos potion... and the Arcane University got samples of her milk. That is where their new research project resides, understanding the effects of the potion after it expires.

To this end the university recruited Leila Agend- a smart and eager woman from the Arcanist wing, and Jerrik Numinous; the ace-student of the Alchemical wing. Jerrik is a serious honor-student; his hair is short and brushed back and his face kept clean shaven except for a soul-patch on his chin. His skin is very pale rosen hue and his eyes indigo. As an academic; while Jerrik is quite tall at 6'4", he is neither muscular nor athletic in the slightest. He is still considered quite handsome by many, and wears a pair of small round glasses that often slip down the bridge of his nose annoyingly.

Leila on the other hand has mahogany colored hair always tied in a voluminous pony tail. Her eyes are the same red wine coloration of morganite. She apparently claims to have needed to grow her hair long just so people would stop mistaking her for a boy- because her hips are not wide which means her butt is also small; but also her chest is flat as a board. Like, she is so flat she could go topless at a beach and no one would look twice- just assuming she was an effeminate looking boy. She is fairly tall for a woman- though not nearly as tall as Jerrik still. Her skin is a soft, smooth brown.

Mae Farlane walked into their research lab in the university after two weeks, just to take a peek at their work. Mae of the Farlane sisters is the magister- she created the magical component that made their potion do... well, anything. Without magic the potion is just a set of genetic instructions that will have absolutely no effect no matter how you take it- it needs the magic component in order to DO anything with the instructions.

She nodded to the work both had done on the project. "It seemed weird the university wanted to keep an expired tonic- but I guess our use for it created an interesting enough situation. You two have handled it well so far too."

Jerrik nodded, motioning over his alchemical portion of the work. "Your spell does not expire. If it runs out of energy the tonic becomes entirely inert. Due to presence of ambient mana- the chances of it burning completely out are slim without deliberately doing it yourself. The physical tonic however is made from organic compounds and will very much expire, and since the tonic is where the spell is pulling its instructions from... it is given corrupted instructions- you get corrupted results."

Mae nodded. "And violently ill, if you attempted to drink it."

Leila chimed in eagerly from the other side of the table, behind the stacks of books from her arcane research. "BUT; if we can find a way to reconstitute the tonic's power, we can create a deathless potion." She pat the pile of books. "As a fellow Arcanist you know more than anyone that there are thousands of transformation spells already- that is nothing special. But what you and your sisters made was a topical tonic that could be handled by anyone. Without a spellslinger present- someone could transform themselves with your tonic... which also has the handy side effect of you being able to transform yourself or others even if you yourself have been transformed into an animal, which would normally disable your ability to cast spells. Brilliant!"

Mae sighed. "But a deathless potion seemed like a fools-errand. To reconstitute the tonic you would need to undo the stages of rot the physical tonic has gone through... you are talking about what is essentially a form of food-necromancy. Even if you could pull it off... at that point it would take so much effort to do it is like... what is the point? Just buy a new tonic." She motioned to the samples they had set out in cryo-capsules. "Till I heard what the mutated potion did."

Jerrik nodded. "She transferred almost perfectly the results, via her milk and saliva samples. Which is what we have here- stored mutagenic milk. The fact that the mutated variant was able to project itself through another fluid entirely means that when one decomposes... you can simply transfer it to a different fluid. It re-writes the fluid itself the same way it re-shapes the person who is exposed to it."

Leila spoke up again. "Buuut that doesn't help if it transfers bad instructions. Decomposing tonic made mutagenic milk. So you get a chaotic mutant bovine instead of a cowgirl. We need a secondary potion that can rebuild the instructions, by back-tracking what the stages of decay would have done. We know how decay progresses. We can look at a skeleton and know whether it was a dog or a human even though it's rotted away already. Reverse-engineer the proper instructions based on what damage we can predict the rot did to it. A potion that can restore potions, and a potion that can self-replicate when exposed to any other fluid."

Jerrik muttered half under his breath. "Well... any other fluid that contains proteins. You can't drop it into the sea and turn the entire ocean into a potion. Nor would anyone want to."

Leila tilted her head. "So... why aren't you or your sister Maggy on the research team? I was surprised when I got the opportunity to co-head this project... it seemed like it would make more sense for the people who actually made the original to be researching this."

Mae blushed. "Eh. I have my own research- making new tonics and elixirs rather than prodding the corpse of an old project. Erm- not to undermine what you are doing, of course! We just... uh, me and my sisters had a unique experience while using these that is sort of personal... and not something I want to mix with my work."

One was an alchemist and the other an arcanist- since the original tonic is both; the University put them together. Rather than work together however... they sort-of just came at the project from two different directions, doing separate research in the same room. It did not help that their personalities were a bit conflicting as well. Leila was energetic and also clearly had some personal gambit with this project working. She is so eager to be done, because she wants to use it on herself as a 'cure' for her flat chest. Jerrik however was taking it very seriously and only in it for the academics. Both out of curiosity on the mechanics himself, and looking to earn himself accolades within the university for a job well done. One attempted to create a restoration method using physical potions while the other attempted to do it with spells. Instead of bouncing ideas off one another- discussions on methods just turned into debates.

Further annoyance to Jerrik however is that Leila kept inviting her girlfriend into the research room and often started making out, with Jerrik just awkwardly in the background. The room is admittedly gigantic for having only two or three people in it, but it is still hard to avoid looking at or hearing them when they are the only other people in it.

Jerrik eventually growled at them to break it up. "This is a research area! I cannot concentrate with you two trying to tie your tongues in a knot!"

Kaylie pouted, but Leila just laughed. "Well that is fine Jerrik, because I am practically done anyway. Once my version of the cure works you won't need to finish yours. But alsooooo...." She leaned so far over trying to reach a paper that she would have fallen off her stool if it wasn't for Kaylie acting as a counter-weight. "Kaylie is part of the team." She waved the paper in the air.

Jerrik immediately furrowed his brows. Kaylie is a Geomancer... she has no training in either of these fields. "What? How? Why?"

Kaylie chuckled. "Test subject."

Jerrik's eyelids lowered. The page Leila is waving around is a consent form- a waiver of rights. Kaylie doesn't know anything at all about this type of research, but she doesn't need to, to be a test subject.

Kaylie has the olive toned skin of an energetic Asian. Her hair is raven black and tied in a long braid that hangs in front of her shoulder. She is shorter than Leila but her bust is a great deal more impressive. Though a bit loose and wobbly- her breasts are an impressive G cup set, with very wide, soft edged areola. Her breasts are a bit on the plump side though so her boobs swallowed her own nipples- they are inverted when dormant. Kaylie has a bit of a soft belly, so her belly button is deep and sits in a long cleft across the front of her belly. Her butt is not particularly round but her thighs are huge! Most of her fat settled in her bust and thighs- so while she is very heavy for her height; she doesn't look particularly fat. Her eyes are green but fade to blue around her pupils- when she is outdoors in the sunlight the blue expands to consume most of her iris.

Jerrik grumbled, giving up for now. He is sure she got Kaylie on as a test subject just so she could have her way with her lover right there in the lab without him being able to kick her out. She couldn't be close enough to finishing her potion yet... can she? Jerrik pondered asking Kaylie for help with his herbs, since she is a geomancer and can flash-grow plants by speeding up the intake of nutrients through their root systems. But he didn't want Leila thinking he was bumming help from her, so he avoided it.

Alchemy was clearly the answer to this problem, not her arcanistry. Sure, you could stabilize the mutagenic milk pretty easily using magic- you'd need to know magic to do it. The whole point of the tonic is that it can be used by anyone. If you already knew how to use magic yourself, you'd just use a transformation spell and not a tonic in the first place. Jerrik is working on a tincture that will use an extremely simplistic low-energy magic- we are talking small enough to be powered by a potato kinda simple. The tincture will basically be introduced with a drop of the original, expired tonic and its corruptive nature would then turn his tincture into a restored potion. The simple spell trigger would essentially compare the differences between the decayed version and his intact version and inhibit any part of the spell that falls outside of that range. His tincture is essentially both a new fluid for the effects to transfer into, and also a filter to prohibit mutations outside of the acceptable bounds.

Jerrik scowls at the two flirting while he is trying to work. Is Leila taking this project seriously at all? She wants it to work to use on herself but does she also understand the risks involved if it fails? They only have two cylinders worth of the mutagenic milk in the first place- once they use that up they no longer have anything to run their tests on. And currently they have exactly one test subject- he is pretty sure not many other people will raise their hands if they ask for a human Guinea pig. Leila ended up staying late that night, which somewhat impressed Jerrik. Maybe she is taking the project seriously? He just hopes she isn't rushing this. She says she is close to something and wants to try and wrap it up. He appreciates her motivation to work overtime but... isn't she rushing this a little?

The next day Jerrik was distracted from his own research watching Leila bounce around putting the finishing touches on a dose and summon Kaylie to the lab with a phone call. He tried to talk her down from testing her version so soon.

"Run tests first, we have petri dishes and a microscope! Induce the effects on a cell sample!"

"What cell sample?"

He shrugged. "Just use a tongue scraping, it doesn't really matter as long as they are living cells."

"Yea, well firstly- cells do not interact the same when isolated from the rest of their multicellular host, and secondly- I have complete faith this will work." He tried to speak up but she cut him off. "The potion doesn't work without mana, and the mutagenic milk doesn't work without mana. Therefore if you can inhibit the parts of the spell- the shapen mana- that make it do things, then it will work. Doesn't matter what the physical mass wants to do, the spell is what makes it function, so if the spell can't do it, neither can the mutagen."

Well that is all technically true- it seems like an oversimplification. The spell also doesn't function without instructions and the alchemical mixture is where the instructions come from. How do you inhibit the results of chaos? You don't know what the mutation will do, so then how do you know you can stop it?

He glanced at her chest then back to her, furrowing his brow. "You... did you...?"

She is normally flat chested- so any size increase would be notable, but it looked like there was melons of at least a D cup range with perky nipples tenting her shirt. The loose grey shirt that would normally completely cover her now exposed her midriff because her breasts were holding it up, hogging the fabric.

"Hmm?" She put her hands on the table to lean toward him, deliberately pressing her boobs together to flash cleavage, pretending to not know what he means.

Jerrik looked to the side to avoid her boobs. "Did you test your stable mutagen on yourself??"

"Oh! You mean THESE? No, no. These are just something I wanted to do for myself. Personal matter- I will thank you not to pry! Pfff, men."

He furrowed his brow with a grunt. "The only thing I want to pry is those obese things out of my field of vision. Keep them to yourself and concentrate on your research."

That would certainly explain her confidence in her potion- but she is an Arcanist so she could have just as easily used a transformation spell on herself. That would seem to be strange timing however. She was eager to be done this project to use it on herself... why would she then use normal magic to enhance herself right before she was done? It doesn't make sense, and Jerrik is almost certain she is up to something. She was again rushing, and remained late this day too, to complete it and give it to Kaylie. Jerrik of course remained as well today to witness the administration of the new potion. Jerrik kept glancing at the clock, then over to the women. He sat in the middle of the giant table while they were both on the far end, whispering and giggling with one another. That was all they were doing though... no transforming. So Leila didn't use her potion on herself? Because why would it work on one and not the other? That made Jerrik's head hurt trying to figure out what this woman is doing, but supposes it is none of his business.

Kaylie glanced over at the clock above the door into the room. "When uh... when is my changes going to start though?"

Jerrik sighed, standing from his seat to leave. "An hour and a half ago. She failed."

Kaylie looked at Leila, and Leila half-shrugged and half-nodded. "Yea... it should have done... SOMETHING by now."

Jerrik shrugged. "If I had to guess- the reversal process you induced reversed ALL of it instead of just the decayed process. Basically; it regards the changes of the spell on the person the same as the changes of decay on the spell itself, and negates the entire thing. It is a transformation and reversal spell in one neat little package, so neither effect does anything." He looked at them over his shoulder before leaving. "Failure is the first step toward progress though. She did not transform- but she also did not mutate horrifically, so you did technically stabilize the mutagen. It is a start."

On his way out Jerrik glanced at the cylinders, then at Leila one last time before slipping out to return to his dorm. That woman is trying something dangerous. He doesn't know what, but he doesn't like it. The first cylinder of mutagenic milk is almost empty. She didn't use that much on Kaylie, so where did the rest go? Did she use it on herself? But she increased her bust, while nothing at all happened to Kaylie so it couldn't have been the same substance. But she also isn't mutating that he can see, so she couldn't have just taken the mutagenic milk straight??

The next day Jerrik was getting pretty close to done, but unlike Leila he did not plan to wrap this up. He wanted to run tests in a petri dish- controlled samples before a whole living subject. No, small tests will definitely not tell you everything, or even most things- but if it fails at that stage it's definitely going to fail a live test. Better safe than sorry. At least when Leila's potion failed- it failed in the best way possible, without doing any actual harm.

Leila answered her cell phone, spinning in her stood happily a ways down the table from Jerrik. "Heeey." He of course could not hear who was on the other end of the call. "Ooookay, well that is a start. Something... up?" Jerrik glanced over out of curiosity. "Tell me in detail so I can diagnose its effects and figure out what is wrong. If anything. You were supposed to turn into a cowgirl- that was the point."

Jerrik sat up straight now. Wait, something DID happen? It was a delayed reaction? Leila's face went from concerned to surprised, to embarrassed and back to a mix of concern and mild arousal as Kaylie described her situation.

"Uh yea... stay in your dorm room for now so people don't freak out. I will see what we can do on this side... I will try to go to you later. Or actually... maybe sneak you into the lab once everyone else clears out of the main building for the night? Would you mind sleeping here in the lab? It might be safer, and I would be here with you and also still researching a cure."

As soon as she closed the call Jerrik made an exaggerated shrug. "What the hell was that?! What happened?"

"Welp. It doesn't just do cow transformations."

"She did not transform into a bovine?!"

"No, it's bovine... ish."

He tilted his head back in realization. "The wrong gender. So she is mutating, but it was delayed?" He smacked his forehead. "Of course!"

"Of course what?"

"Mana. The original works so well because all of the instructions are on a physical medium, the mana just makes it run. It is like a machine and its supply of gas- if you run out of gas the machine stops working but it's still there- you can still refuel it. Your induced orchestration runes had no physical medium to be tethered to, so if the amount of mana dips below the threshold they poof out of existence entirely." He sighed. "See? The whole point was making a potion that would work away from a caster, but your cure was entirely magic based, so it only works as long as there is a high supply of mana to maintain it, or a spellslinger to focus mana directly into it. It wasn't really self-sufficient."

Leila grunt in frustration, pouting as she flopped on the table in front of her. "Well, time to roll out your plan B. You think you have such a better grasp of this- by all means."

Jerrik grumbled, glancing at his research and then her. "I don't have anyone to test it on even if I wanted to. We only had the one volunteer."

"So give it to Kaylie? She is the one who needs the cure."

"...NO. If it somehow doesn't work, I would guarantee she turns into a horrific abomination and also extend the time she would be forced to exist in that form. Even if it works it would make her current condition worse. Just... worse in a more controlled way." He grunt in frustration. "I will take it myself. I don't need to sign any formal consent forms if I am doing it to myself."

Jerrik really would have proffered to test this more, but at least he doesn't have to feel bad about messing someone up if it does go bad- because he will just be doing it to himself. He was not particularly keen on turning into a half bull, but such is the sacrifice he must make in the name of his research. If his cure doesn't work, they will need to keep Kaylie transformed in order to use her as part of their research to find a cure that does... and she might not be done mutating, and he is sure she will want to be normal again sooner rather than later.

Jerrik finished his tincture, popping it out of the mixer- the liquid still a bit frothy at the top from the machine speed-steeping the materials using a highly pressurized chamber. He paused, absentmindedly looking at the slightly cyan tinted liquid before drinking it. A shiver radiated through his body from his stomach. It certainly feels like it is doing something. Jerrik suddenly felt a bit empty headed, like his thoughts were slowly floating away from each other, making it hard to connect the dots. His whole body felt strange, but in a way he is entirely unfamiliar. It is a subtle sensation that makes him shiver a bit or squirm in place. It isn't an unpleasant feeling at all, but it's unpredictable and comes and goes seemingly at random all over. It was like his body was having a hard time deciding what part to change first.

He felt... sort of alone suddenly... like he wanted a hug? And sort of horny, oddly. Leila is a good looking woman... er, but he has no interest in her! Right? Why does he feel so horny though? He blushed a moment at the unfamiliar feelings, and then in a sudden wave he felt pent up! A light pressure inside his balls! Now he really blushed. Oh really, his genitals? It couldn't have started with horns or ears, or his feet or something, it went straight for his junk?! He should have known all along that was a very real possibility, but suddenly he was flustered by it! He did not want Leila to see his genitals mutate!

"A-ah, I just realized something I forgot; I got to get going!"

She cocked an eyebrow. "Uhm... the tincture?"

"It didn't do anything- and I think I already know why, I have to review some of the research papers back in my dorm. It is time to wrap up for the day anyway." He very quickly hustled to the door, but then hesitated. "A-and... just in case I do not come in on time tomorrow- then it changed me in the wrong way, but on a delay like Kaylie and I am probably in trouble. Just... just in case, y'know?"

"Mmmhmm. Oh don't worry, I would definitely know something was up if you were more than twenty seconds late."

He isn't that punctual! Well, he doesn't do it because he is a stickler for rules, he has a key to the lab so there is no reason to wait around for someone else, he can get into the school on his own, so why not come in earlier?

He tried to make a beeline straight to the dorms, his face felt hot and he became dizzy. Hormones going apeshit. He felt pressure and then a dull ache in his lower gut- no idea what that was. He finally got to the dorms and leaned heavily on the doorway a second as he felt his tail bone extend out into a bull tail! Pressure built at the base and then the tail itself grew out rather suddenly in one long motion, but the somewhat pleasant feeling caused him to freeze up because it was in such a foreign place. He staggered and nearly fell over walking into the hall when his tail was assaulted with a prickly feeling of the tassel erupting from the end of it. His hair is a golden brown- the tassel adopted this. He held his stomach as the ache became worse. It did not really feel like a cramp exactly- the ache was getting powerful but it wasn't sharp. He lifted his button up shirt a moment and his eyes flashed wide when he seen how pink his lower gut looked. That isn't..? No, it couldn't be. Unless it is. Kaylie got traits from the wrong gender... if his method of control over the mutagen doesn't work, he could very well end up with the wrong gendered traits too.

He almost fumbled the key to his room when he finally arrived. Horniness, head spinning, aching, could not concentrate. He slipped inside and immediately closed the door behind him, then slammed his back up against it and got onto his tip toes, groaning loudly as his guts felt like they were shifting! Pressure- the ache was starting to let up but now it felt like something pushing on his pelvic floor?! With a yelp of surprise a massive egg erupted out of him into his scrotum! The pressure hit again immediately after and he grunt and pushed , birthing a second one into the other side of his scrotum! He immediately reached down while gasping for breath, gently feeling them. Yup, those are indeed testicles. A bit more oblong than his own, and an oddly pleasurable pressure and weight building in them told him they were still growing. Those are bull testicles. Rather than transform his balls into a bulls'; it just grew a whole new pair. That... shouldn't happen. But it isn't... wildly outside of what it should do, he supposes.

He dipped his pants down a moment so he could flick his new tail out the back, and sat on the edge of his bed. "Well... maybe this is fine? Bull tail and testicles... given the size of the dose I would have expected more changes but this is technically all within its expected parameters. Granted- this is not how I would have expected it to give me the animal testicles."

Jerrik got his clothes off and got into the shower to officially end his work day, but the moment he ran his hand down his body it paused on his stomach. Oh no. When the balls popped out he assumed it would go away... his lower stomach is still bright pink. He felt around the tender skin and found four points where it is stiffer than the rest, and the moment he brushes over them they start to erect, standing out like little bug bites! He quickly took his hand away and just gawked at the four little nipples, hoping maybe if he did not stimulate them they would go away.

He did not account for the shower water through- the slightly cool water he uses to refresh after a long day in the stuffy halls of the research wing still pattered against the flesh and made him moan. His bull balls were slowly enlarging since he birthed them- and now were twice the size of his human testicles! His nipples stiffened, tingling a bit as the blood pressure engorged them and then stretched them still bigger. The bright candy pink of the circle of flesh under them started to rise up in four gradual slopes... a segment for each forming teat.

Bull balls but a cow's udder? Yea... he is starting to think his control mechanisms did not work, and the potion is still just chaos. It was a little TOO simple. It inhibits effects outside of a range, but the potion is not self-aware; it has no way of knowing WHAT features to weed out. His theory relied on it applying a proper cow transformation and then adding too much or growing things beyond their normal parameters for it to work. But that was never the case- what features, proportions, or ways it manifests those features is entirely random. It will prevent him from mutating wildly into some blob of disfigured organs but there is still no guarantee which traits he will get and how they will manifest. Basically his tincture narrowed down the amount of mutations he can get- not which ones he gets or how badly they turn out.

With Jerrik's legs parted a bit, his scrotum starts to hang lower. It already expanded in width to accommodate the second pair- but the weight of the huge bull nuts was stretching the scrotum longer too, allowing them to swing around more wildly. The larger the segments of his udders swelled the more defined and round they got- a wall of muscle helping divide the segments and also help the overall udder retain its shape, since the rest of the tissue is too soft and amorphous on its own. Jerrik softly muttered at it to stop growing, as if it could somehow hear him. After an initial surge the growth seemed to slow to an absolute crawl... but it also did not seem to entirely stop. At risk of running his water bill through the roof- Jerrik decided to just finish the shower in spite of it.

By the time he got out to pat himself dry his nuts were swinging around his knees! The udders looked about the size of a D cup breast each with little finger-sized teats! He went very slow when he dried the udder off. It was still growing very, very slowly, so the skin remained very tender- even lightly brushing it triggered pleasure because all the nerves were pulled taut by the unending growth. It felt really good, making it hard for him to not enjoy having it. But... he shouldn't enjoy having it, right? It is a female part on his male body, and a sign that his work failed, he should be angry at it! Hmmm, but he still felt like he needed a hug. To be touched... to touch it, squeeze the soft flesh.

He wandered to his bed without even getting his underwear back on and flopped into the bed nude. As soon as he felt the cool sheets on his udders he reflexively thrust into it. He bunched up the blankets into a ball and squeezed his udder against it, moaning. Jerrik rolled over onto his back, pinning his twitching tail under the weight of his nuts sloshing around between his legs. In a surge of pleasurable pressure and the feeling of needing to cum- his bull testicles grew rapidly! They were already full size; they are growing beyond a normal bull now! His scrotum slowly reeled itself in- needing the extra loose skin to give room for the mutant balls. At the exact same time however his nose felt terribly congested and he scrunched his face up at the feeling.

Jerrik sat up, shoving a pillow behind himself to help prop himself up... and was confused a moment when he seen his hair. His hair is growing longer- it shouldn't be long enough to enter his vision. He did not have long to think about it before his vision vibrated from the force of the cartilage in his nose popping loudly! The bridge of his nose suddenly became wider! His nostrils enlarged getting wider than they are tall- the expansion of the bridge of his nose helped keep up. His jaws extended ever so slightly and his teeth all enlarged and became more blunted to occupy the added space! Jerrik's upper jaw and bottom of his nose expanded forward till they became perfectly level with one another- the bottom of his nose now facing forward rather than down! The diffused red of his lips advanced upward and took the entire front of his nose too! Jerrik's face looks like that of a bull, when viewed head-on!

His heavy breathing from the assault of sensations started to sound like grunts and snorts of a bull. His bull testicles stopped a bit larger than a basketball each- though squashed oblong in shape. His poor human balls looked like little chicken nuggets in comparison.

"P-plea...ease.... nnngh... can't take it. Can't wait for it to stop!!" He grunt several times, bending himself a bit further forward and reaching around under the udders to grab his erect cock!

The balls felt swollen with internal pressure, like there was an entire high-pressure lake inside his nuts that needed to get out. He was half expecting to erupt like a garden hose the second he touched his dick, but the dam in his nuts held out better than that. The pleasure tensed with every movement of his hand on his shaft, but he also created another pleasure from his udders- because in order to reach his penis he had to reach past the udders first. Every jerk of his hand wobbled his tits around, and encouraged them to keep growing. Now each segment like an E cup. They project out even when on his back, wobbling around very loosely. If they were breasts of that size; they would roll off either side of his torso. Because they are all fused in the middle however; the left segments pulling left prevented the right segments from falling right- they stabilize one another.

It felt like someone tugging gently on his ears and he moaned from the feeling, knowing it must be him getting bull ears. Well... that much is supposed to happen, so that change is fine. He did find it odd he was not yet growing horns. His hair was still inching lower as well... neither cows nor bulls have hair, they have fur- so his hair shouldn't be growing at all! It started to block his vision but he was too absorbed in masturbating to bother to brush it away. It is not like he can see anything without his glasses on anyway, so he wasn't missing anything.

Every time Jerrik's bull balls lurched up in a clench he felt his human balls roll down and then back up the front of them, forced to share the same chambers as the bull endowments. The udder flesh started to brush against his thumb more and more as he masturbated while they just keep growing- their bloated sides threatening to smother the area his dick occupies. The flopping teats now looking like large fingers! He felt a squirming below his skin and squirmed a bit himself from the odd feeling, looking down at himself as giant veins bloated out of the surface of his torso around his navel, trailing down into the udders while branching out into smaller, more numerous veins! The candy pink coloration of the udder trailed up the surface of these veins a bit.

Jerrik groaned and arched his back from the surge of pressure and pleasure as the skin suddenly pulled taut! The udder segments became unnaturally round and firm- the teats standing on end and vibrating from the sudden movement! His groan unintentionally sounded like the lowing of a cow!

"Uuugh! S-so... full! So tight. So big and tight annnngh full and good, and good... a-ahn so g-g-g-oOOOOd!" His eyes widened at the moo-like sound he unintentionally made.

The tissue pulling taut on its own rather than an outside force triggered all the pleasure receptors in the udders all at once! The milk veins forming fed the tissue the nutrients it needed- their growth sped up! He was unintentionally shaking his tits up and down in order to touch his dick! To move his hand on it, he had to rock the udders upward to make room, otherwise they would steamroll his crotch! His toes curled in pleasure, but the coloration shifted in his nails- a surge of more keratin thickened the existing layers and caused his nails to turn milky, then light grey, base grey, dark grey, and finally glossy black as they became four times as thick as they are supposed to be!

Jerrik curved his back again in pleasure and fired a stream into the air a full second long before his cock clenched to interrupt it... but it was perfectly clear. That isn't cum, it's just pre! He felt a tickling pleasure fire up, bloating the cords connecting his balls to the rest of his body, and then right back down- into his other balls!! His human balls overfilled, tingling, aching! His bull testicles are ejaculating into his human testicles! They are like seven times the size, his human nuts can't take that! His orgasm trails on in pulses- his urethra throbbing and firing up streams of pre. The balls ache immediately and start to bloat larger. His scrotum starts to draw tighter as it runs out of space for the nuts inside- the natural crinkles in the skin are pulled perfectly smooth and the flesh starts to blush the same candy pink his udders are from being pulled around! As his balls grow however; the ache becomes accompanied by small sparks of pleasure. Then a warmth, then a more constant pleasure, and then a stronger pleasure. Bigger they get and more oblong they become the pleasure remains consistent while the ache starts to fade! His balls reacted adversely to the wrong type of sperm invading it- but as they are forced larger they mutate to be more bovine... till the bull traits are what is familiar, and the human traits are what are regarded as invasive! Less ache, more pleasure as his balls accept their fate- being trained by the second set on how to be bull!

Jerrik continued to masturbate red-faced and desperate, as his penis erupted pre and his original balls engorged , bloating to the same size as the new ones! With a mighty clench, his new bull balls scrunched up to his pelvic floor and Jerrik howled from the pleasure exploding as the next eruption from his cock was finally white! The swapped load finally made its way out, and his first set of balls emptied its mutated load. Jerrik had barely enough control over his motor functions to put his hips as far off the bed as possible- so his ejaculate thudded against the wall behind the bed. His tincture did not work... which means his semen will have the same mutagenic traits as the original milk samples. If he gets his own spunk on himself- he will compound his mutations. That unfortunately means he also has no way to clean up the mess right now- because he can't clean it without touching it.

He collapsed, breathing heavily and grunting for a while, just staring at the roof as his thoughts slowly fade back in. He rolled over and hugged the blankets close to himself. Why does he feel so... vulnerable? He wants someone to be there to cuddle. Is the mutations messing with his mind? He did feel freakishly horny too. Even after release he still feels a bit horny. At least his mutations seem to have stopped, so exhaustion won over hormones and he went to sleep early.

In his sleep he had such strange dreams. Sitting in class but there was cows in some of the seats- listening to the lecture while propped up on the desk like a normal person. Then he fell through his own desk when trying to stand up using it as balance, and fell into grass? A field with cows and bulls. Licking him, brushing up against him. Then a sharp pleasure and he is knocked forward- something abruptly thrusting into his butt! He thought he was wearing pants but looks back and there is no clothing on him and also no one behind him. But then it thrusts into him again- he cannot see it, it looks like nothing is there but he can sure feel it! It thrusts in with such force it takes all his strength to brace himself on the ground- never mind trying to get up onto two legs, he can barely keep from letting it shove him forward back into the ground fully! The grunts and snorts... a bull? The weight on his back, the pleasure throbbing in him... is he getting mounted by a bull and... enjoying it?!

Jerrik woke up with a gasp! It is still pitch black even though his blinds were left open- he passed out early so ended up waking up so early in the morning that the sun was nothing more than a faint orange glow on the horizon. All four of his balls squeezed up against his torso making him shudder.

"Sss-s-so horny again? B-but I just... nnnngh." He placed a hand one on of his nuts and then looked down at them in surprise waiting for his eyes to try and adjust to the dark- but without his glasses all he was getting was a blurry outline at best. "Bigger?!"

He groaned, realizing that his precum must have caused minor changes. It would not hold the mutagenic abilities of his actual cum but it must still transfer something- because that is the only thing he got on himself last night. His balls and udder are both larger again! His balls fill the space between his legs and his udder rests fully over his lap- his penis is jutting into the underside of his udders. Each segment of his udders is the size of medicine ball and his testicles almost exactly the same- just a bit more oblong without needing to hang off him. His balls are a lot more solid than the udder so they hold the same shape regardless of how he is posed.

Jerrik went to masturbate immediately to relieve the tension but met only the surrounding flesh! He could not even reach his penis- it's wedged between scrotum and udder! His dick has to point straight out because the udder's weight on the back of it aims it forward when erect, it can't stand upright because of a lack of room! Jerrik grunt and flopped back onto the bed into a resting position so his udders rolled back on the crotch over his groin, and his testicles rest between his legs so he could wedge his hand in there to reach his actual dick.

Jerrik kept unintentionally remembering his dream. He wanted a bull to penetrate him... wait no he doesn't! Or... he shouldn't. Or something to penetrate him... his butt feels empty... hungry. His dick is so hard to use now, it would be a lot easier to cum if he had a top. His hand brushes the top of his front balls and shakes his udders back in order to make room to work his cock- but his udders are too elastic and their weight causes them to slosh right back in the way to be bounced off again and again! The pleasure spiked high quickly- but his pleasure the night before hung at near orgasmic for quite some time before he actually came so that doesn't necessarily mean much.

He groaned at the wet clapping sounds he was unintentionally making against all the soft, amorphous flesh both above and below his dick. His face felt so hot... the bridge of his nose felt tight, like it wasn't sitting right on his face. Oh no. His precum- again! But... he can't get off without leaking pre, and he has to get the pressure out! Two full balls is hard enough to say no to- four at once is maddening.

Jerrik half-rolled to his side before returning onto his back. NOPE, that won't work. If he was on his side or flipped onto his hands and knees he could jack off and let the pre drip away from him instead of ON him- except in any position other than on his back his udders and balls swing into one another and completely block access to his cock! His only hope is to try and get off as fast as possible! It was almost unnoticeably slow with the flesh rocking around so vigorously but all four balls and his udders are swelling again! Which means it's a little bit harder to shove their weight away from his groin to move his hand, and his balls already filled the space between his legs, so as they grow; they rise further and further up toward the underside of his udders! Even on his back the gap is closing! His penis itself is entirely unchanged, so it's being utterly smothered by its surroundings!

He is mutating himself, but he needs to get off! Feels so good, can't stop, trying to stop would be agony! But continuing is changing him worse! The udder started to flop ON his hand instead off of his hand, forcing him to lift his hips to try and get them to naturally roll back! He is running out of space! His scrotum can no longer hang- there is only enough slack in the flesh for his balls to squirm against each other and bounce off his pelvis when they clench. Each testicle is bigger than his entire damn head! He felt the white-hot pleasure peaking, all the muscles in his groin clenching as hard as they can. Yesss, yesss do it, get out, blast it out! He unintentionally remembered the imagined pleasure from his dream of a bull thudding down on his back and thrusting in and he hit climax!

His cum blasted against the underside of his udder! Ack! He tried to angle it down but while erect the shaft doesn't have that sort of bend to it- the udder was already forcing it down as far as it can bend! He blasted against his udder, getting all over his hand and dick and then pooling in the cleft of his balls! ALL of his cum was getting trapped ON him! His skin tingled, then his muscles tingled. Oooh no, mutagenic cum! And soooo, so much! Last time he had a human and a bull load that swapped nuts. This time he has two full loads of bull- double the amount of cum! The only saving grace now is that his cum is not easily absorbed. It is so thick it sort of just coats whatever it touches- it's too dense to easily absorb into anything, unlike mutagenic milk. The moment his orgasm started to taper off, Jerrick rolled onto his hands and knees off the side of the bed, splattering a lot of the load out from between all his flesh onto the floor, then got up to go to the bathroom, but wobbled in place trying to get his balance. His balls and udder are both every heavy. They actually look almost exactly the same! They are the same size, both have four segments, both flop and slosh around easily. The only difference is his balls obviously do not have teats, and are actually less veiny than the udder is- at least at the base. His penis is absolutely buried in the flesh, and he cannot move without causing at least a bit of pleasure because his dick is getting rubbed by the hot smooth flesh.

Jerrik's movement stuttered halfway across the room and he let out a long, strained groan as his face started to push out. He then snort many times getting his breath back. Oh no, he is growing a muzzle! He took another step and it almost sounded like he broke his leg! Several bones popped in his foot, and both feet rapidly started to lengthen! His shins started to get a bit shorter as his feet stole mass from it!

"Aaagh, f-frick, h-hoo-ooo-OOOOUUHves!" He winded himself lowing like a bull on accident!

The longer his mouth stretches the harder it will get to pronounce anything. His feet quickly became too long- he could not walk properly on them, they will drag on the floor because his legs can't lift high enough normally for them to clear the ground! He tentatively bopped the ends of his toes on the floor and yelped in surprise when his block-like nails expanded so large and suddenly they shoved the flesh around them out of the way, completely taking over the end of his digits. Well... there ya go- hoof enough to use. He eased his weight onto one and then the other and staggered the rest of the way to the bathroom even as they continued to change. It hurt because they are nowhere near done changing but he needs to get the cum off or the changes are only going to get worse, so he could not afford to wait.

He grabbed the doorframe, having barely staggered to the bathroom on his shifting feet. His grip loosened without his input and he looked worriedly at his hands as they too started to shift- stealing strength from the muscles as they malformed.

"Nuh! Not moo hands! I n-nUUHHeed moo hunds!"

His vision went so blurry for a moment that everything for a moment looked like a solid blob of brown. He was hit with a wave of dizziness and the vertebrae in his neck started to make a rather sickening crunching sound- they are expanding! Each vertebra is getting longer, pulling his neck larger! Well... now he is definitely not going to be able to talk. No voice and no hands- probably going to be real tricky to finish his research.

His strained groans became deeper and deeper, his voice getting locked into a thunderously low pitch. The tickle of black fur spreading on the bridge of his nose made him scrunch his face up and shook his head, snorting a few times in irritation. His human hair was still growing too- now long enough to touch his chest in spite of his neck also getting longer. Still no horns even as his head enlarges and pushes out, deforming to a bovine shape. It isn't a bull's head, it's a cows. His leaf shaped ears flicking wildly from the feeling of black fur spreading on their backs as well.

Jerrik scrambled into the bathtub, scoot his hips forward so he was under the tap and dumped the water directly into the cleft between balls and udder. He put his malformed hands on the udder and pulled the flesh up the best he could so as much water as possible could get in there and wash away the mutagen. Unbelievable- directly coated in mutagen, his dick still refuses to change in any way, still perfectly human.

His middle two fingers and toes grow giant, the hoof segments now a curved pyramid shaped and rather sharp since they have never been worn down on any surfaces.

"Nuh- Noooouuh!" Jerrik scrambled to try and grab the tap to hold himself steady but he was sliding backwards now, out of the reach of the water stream!

Not just his feet- his legs are getting... wait, not longer... bigger. His legs enlarging was shoving his body back against the front of the tub to make room! The bones inside swell massive, then the muscle and then even his skin thickens on their surface! Millions of tiny, short soft hairs sprout causing a pelt of gold to fade in across his entire lower body! His hips were also enlarging, making it sort of feel like he was being lifted up higher. He grunt loudly and then snorted as his pelvis popped loudly- expanding much wider and also changing shape... sharper pelvis... bovine hips. He fell backwards, but as he fell he managed to jam the pull-trigger for the shower head between the two segments of his forming rear hooves and pulled it as he fell!

Jerrik could no longer reach the actual tap- but the shower turned on and started to rinse him the rest of the way off. He made several odd stuttered lowing sounds trying to form words, realizing he was already unable to. Jerrik snorted several times, blowing off a mist of shower water with the gusts of air as his face continued to stretch longer, forcing his eyes to the sides of his head. His forehead angled along with the bridge of his nose; tilting further and further up till his face was so long it was flat with the top of his head, pointing straight up when his head is level. While his neck grew huge the skin on it oddly seemed to grow faster than the neck itself, causing it to bunch up and then fold and sort of pool. It took Jerrik a few moments to realize it formed into dewlaps- it just looks weird because he is on his back so they're folded back against his neck instead of hanging off it.

He made a whimpering sound as he held up his hands and watched them devolve further, mirroring his feet. Jerrik supposed that with the amount of mutagenic goo he blasted himself with, he should consider himself lucky he doesn't grow a second head at this point. Which is something that actually happened with the last people to do this. His balls and udder are STILL growing as well- not very fast but they are already so big that any growth is bothersome! In his squirming however; Jerrik discovered something far more alarming. His legs slowly started to rise as his feet finished devolving into cloven hooves. He isn't listing his legs- his legs are lifting themselves.

His thighs became much more broad without thickening any- the tendons and muscles spreading widening the pivot point with his pelvis as his pelvis also finished taking on a bovine form, putting his anus into a triangular pocket between the sharp points of his V shaped pelvis- hidden under his bull tail. Fully shapen and fully sized legs and hips of a cow... it is locking him into a quadruped form! His legs are lifting because it's becoming physically impossible to put them straight out or to the sides! Never mind losing the ability to use his hands- he won't even be able to attempt to pick things up between his hooves because it's going to lock him onto all fours!

Poor Jerrik could barely even watch as his body mutated- the water was matting his now long black hair and blocking his eyes. His legs cramped from the muscles tightening into their new formation, forcing him to follow along with their tugging till his legs were straight up in the air in this position, bent at the knee and ankle, but unable to pivot around at the pelvis because they just don't work like that anymore.

Jerrik kept grunting from his heavy breathing, slowing down as the changes stopped. Well, that went from bad to worse real fast. He is actually overall fairly normal looking bovine, except the fact he got cow traits even though he is supposed to be male, and grew an extra set of giant nuts in spite of getting otherwise female traits. The fur also awkwardly stopped at the hip- it trails slightly up his back but not far at all. All the mutagenic cum was blown into the lower body.

Jerrik could not properly use a towel so he remained in the tub and attempted to shake as much of the water off as possible, whipping his now long hair around, slapping everything around himself. His glasses are on the counter beside the sink. He can pick them up with his mouth but then how the hell is he going to get them onto his face? Even as a cow everything more than seven inches from his face is blurry as heck. If you held a book a foot away from his face, two or three lines of the text would just overlap one another and look like a solid grey line to him. Jerrik also has a little tuft of fur that is a bit longer than the rest on his chin- where his soul patch had been. The fur that consumed his head trailed down his neck but faded back to skin at his collar, and dipped slightly lower on his spine. Golden brown like his hair is. His dewlaps are extremely long for his size- the thick folds of loose skin wobbled around under him almost low enough to brush the floor.

He stepped over the edge of the tub, then went to step with his hind legs but it was awkward as hell and he isn't used to being on all fours like a beast. The udders caught on the edge of the tub and pulled back, causing pressure to surge into his teats and a sharp pleasure that made him low. He leaned forward and thrust with his hips, plapping his balls against the backside of the udders, and squashing the udders against the side of the tub- causing streams of milk to erupt into the tub! He is lactating! The milk is mutagenic- but it is also just going down the drain in the tub harmlessly without actually touching him. The strong throbs of pleasure kept him rocking his hips, milking himself against the edge of the tub without even consciously thinking about it. The pleasure made his mind go blank.

Hump, pleasure, squirt, sharp pleasure, hump, pleasure, squirt, sharp pleasure. His sack of fruit behind the udder kept clapping against them when he thrust- since they are both smooth surfaces and curved it doesn't take much force to make a loud clapping sound. The balls started to undulate, tensing and rubbing against one another since the two sets had slightly off-timing from one another.

*Oooh I need to cum- STOP! I need to stop! It just...mmmm, good, m-milk but NO! I m-make it worse. Already so bad... what does a little more mat-trrRR- NO. I really shouldn't but I just... little.... more...nnnngh...*

The more he humped the more the tension built and the higher his pleasure spiked, making him want more, making him want to cum. But orgasm is exactly why he tries to fight it. He is starting to leak pre... mutagenic pre. His dick is trapped between balls and udder- so grinding them together rubs his dick in their soft, smooth flesh, sending waves of pleasure through him. But any fluids his cock happens to leak is also trapped between the two and will mutate him even worse. He has four gargantuan balls, so at this point his refractory period is in the negatives- never mind being ABLE to cum, he NEEDs to cum after a short while.

He groaned long and hard then snorted several times trying to catch his breath back. He could feel a pressure all over... his hips, tail, legs- everything down there is growing! Growing to the size of an actual cow! Or bull. Or whatever the hell you want to call this. His udders bloated fatter and his balls rounder and heavier too! He has to stop, needs to stop... doesn't want to stop. The pleasure is mind-numbing but without his conscious input his body will make him cum entirely on its own reflexes. As his milk supply dwindled and became harder to express like this, he was able to slow down and force himself to stop, even though it was mental agony to do it. He finally stepped over the tub and got fully onto the floor- almost falling face-first into the floor!

Jerrik's body is now extremely lopsided. His upper body is still entirely human, and his arms are totally human except his hands are replaced by hooves. His legs and hips are entirely cow, which means they are four times as long as his arms. He cannot stand on two legs, but on all fours his ass is high in the air and his face down toward the ground because he is so unbalanced! His head and neck are entirely cow except for his hair- but at the very least they are sized appropriately for the body they are attached to still, his hips and legs are not. The udders are the size of a prized Holstein's- each segment the size of a medium beach ball or large pumpkin squashed into an oblong shape. His testicles still match this but at this size- his testicles are actually a bit rounder than the udder segments, and also start further back and up, so his front balls rest on the back of the udder and his back testicles rest on those balls. So his four-pack scrotum is being held up and pushed slightly back by the size of the udders. They do still also look like udders themselves- minus the teats.

Jerrik looked to his glasses on the counter- unable to lift his head that far without plopping his ass down on the floor completely, and risking sitting on his own nuts; he has to tilt his head sideways to look up to them. They rattled a bit in place and he let out a jet of air, blowing his head a moment to recover himself. He is trying to use a spell to pick them up and put them on his face. Normally that would be an extremely easy spell... except you generally cannot use magic while transformed. The transformation itself is induced by shaping a mana flow overlapping your own, which means when you go to shape more mana, the spell that is already active (your transformation) interrupts the flow. Jerrik is a stubborn man though- and bovine are bull-headed too. He kept rattling the glasses, dipping his head back and forth trying to line it up and eventually knocked the glasses off- catching them on his face! His face is a full cow muzzle now, but did not enlarge to the size of a cow so his glasses still... sort-of fit. They only help when looking forward though- and his eyes are now on the sides of his head, so straight forward is actually his peripheral vision now.

By now the sun is up, but just barely so- the lower parts of the sky are still pastel pink from dawn. Which is very good- because there is no chance in hell he is going anywhere without someone noticing and freaking out... unless there is no one awake to be able to see him. He cannot speak or use his hands to try and communicate, so if someone attempts to help him without knowing better they may get his milk on them and then mutate themselves. Jerrik is a walking biohazard in his current form. He needs to return to the lab as a safe space, and also as close to where the cure is going to come from as possible- even if he himself is incapable of helping to make one at this point. He cannot wear any clothes, which was doubly embarrassing for him with his giant nuts held up on display by his udders and his butt high in the air like an invitation.

He glanced around his dorm as he slipped out; at first looking for possible early risers in the hall, but then pausing in thought at the pipes on the corner of the roof. Mana inductors. There are inhibitors all over the city that syphon mana and draw it to the campus for the people at the Arcane University to use, and making it much harder for the commoners to try and home-brew something in the streets and blow the place up. In the dorm, there are inductors you can activate that release ambient mana into your room if you deplete the existing supply by testing spells. He could in theory reverse the flow, and vacuum the mana out of his dorm room. If he can get the mana in his body to burn low enough the mutagen will lose its power and become entirely inert. After a few minutes thinking about it and how he could make it work- he grunt and continued toward the lab. Wasn't going to happen. Every possible way he could think of to do that would require having hands- which he currently does not.

His udders are so large his teats actually lightly brush a few dew-laden blades of grass as he cuts across to the main building, saving whatever little time he can by not bothering to use the stone path. He walks with an unintentional swing in his hips, also making him blush- though his fur hides his rosen cheeks. His thighs are fully bovine so he cannot move them very far out to the sides- you will never see a cow do the splits. But the udder is gargantuan; it brushes the inside of both thighs no matter what. Because there is a divot in the middle his inner thighs fit into it. He has to make exaggerated steps and swing his hip a bit in order to fully step, because his leg also pulls the udders forward a bit in order to move properly. His udders are so heavy though that when he really starts to move the swing of the giant tits tugs on his hips- they are so heavy they move his hips for him! This means he cannot stop abruptly- he has to gradually slow to a stop, because if he attempted to just abruptly stop the udder would swing forward and yank him face-first into the ground. Walking for any distance is hard on his arms- they are still entirely human so only a fraction of the musculature his legs have. His body is formatted like a sandwich; a third cow on either end with a layer of human in the middle.

As a human Jerrik could get from his dorm to the lab inside the university proper in about nine minutes without needing to break into a full run- yes, he has timed it. Just going by how the sky has changed color and how much higher the sun got by the time he was inside the outer glass doors and darting to the lab doors- this trip took around twenty minutes if not more. He tried to open the door with his mouth like he did at the dorm... locked, oh fantastic. Why is it locked? Is it still too early? Is that oaf Leila late? If he waits too long, people will start showing up. No one else should want to go to the lab, but plenty of people will be heading to the stairs only twelve feet away from the door.

His ears perked up when he heard a muffled voice inside! No; Leila IS here, she just locked the door behind herself for some reason. Jerrik obviously has a key to the lab himself, but he did not bring it with him because he can't pick it up or use it without hands. Jerrik pawed at the door a few times with his front hoof, but could not balance himself for more than a split second before he needed to clap it back to the floor to hold himself up. With a grunt of frustration he lowered his head and rammed the door! He has no horns at all, so the flat of his head made quite the boom against the double-doors. He waited half a minute and went to charge again, but Leila opened the door, causing him to fly past without meaning to and all four limbs slipped out from under him, collapsing onto his chest and chin against the floor, which squashed his udder further back, which raised his balls on an even higher pedestal of flesh to be seen.

Leila blinked in confusion several times. "O-oh. It is just a mutant Jerrik. What happened to you? When did you start mutating?"

Leila looks mutated too now! Four breasts, an ebon udder... four ears? She is by far the most human of the three but how did she mutate in the first place? Had she created still another iteration of her cure while he was absent? That would mean she was up all night in the lab without sleep? Or did she actually use the original mutagenic milk on herself like a psychopath? He honestly could not guess with this women- and it isn't like he can ask her currently. His head was already starting to swim again with hormones... these four mega balls do not relent.

"Muh."

"Huh?"

"M...moo. Muhmurr, rrugh." He let out a jet of air in frustration.

"Oh... you can't talk anymore. Welp, not getting any answers outa you then." She motioned over to a colossal Kaylie at the back of the room. "Join the club."

Looking at Kaylie- Jerrik started to wonder if perhaps that is what mutated Leila. Getting Kaylie into the lab from the dorm may have exposed her to mutagens that Kaylie would be producing. Kaylie looks to be about twenty feet tall, and her upper body has almost grotesquely bloated musculature- but the way it grows almost looks like her normal body sunk into someone else's body who was much larger than she is, because the vast majority of the muscle bulk is exclusive to her upper back, neck, and arms. Her abs are built like a brick wall too- but nowhere near that size. Her breasts have enlarged to be huge, and her nipples no longer inverted, but compared to the size of the rest of her; this is probably the least impressive change. Her head is still human but her neck is so bloated with muscle its twice as wide as her actual head- and she has four bull horns that look almost comically giant in comparison.

Kaylie stands on bull legs, but they are more narrow and tall than a normal bull- and her pelvis did not change shape, so she is still bipedal. Most daunting of her changes is her testicles approaching the size of a beanbag chair each, in a scrotum that is longer than the average person is tall. Even in spite of the size of her nuts- Kaylie's scrotum travels to the ground and pools for another foot before reaching her actual balls, so she cannot move without dragging her testicles over everything she passes. The skin of her sheath is almost as thick as Jerrik's forearms- and so wide you could slide a fire hydrant into the opening with almost no resistance. She let out a deep grunt and glanced away as not one but three pink tips slid out the opening, already starting to drool pre. Ah, well... that explains why the sheath is so giant- she has three dicks.

Jerrik has a lot of female bovine features- and the hormone balances have messed with his head a bit too, but he has no vulva... so he is technically still male- he has full male genitalia it's just a little hard to recognize them in this state. Kaylie on the other hand has no vulva anymore- she fully mutated to a male... though, she does still have her breasts and her facial structure has remained unaltered. She was clearly embarrassed by her slowly emerging dicks. It took Jerrik almost half a minute to realize he was gawking right at them the whole time, mesmerized. No wonder she is embarrassed- he won't stop staring at her! What... is arousing her in the first place though? Jerrik had a hard time not thinking about them.

Her form fascinated him because... well, that is what he is researching in the first place. But the fascination quickly devolved to arousal and lust. He kept remembering the dream of the bull mounting him. He wants to be penetrated so bad- maybe that would finally completely empty his balls and clear his head for more than five damn minutes! Jerrik also could not sit down without unintentionally hurting his nuts- his udder's weight on top of them is too much. He backed himself into a corner and rubbed his butt up against a stool, feeling his dick push through the flesh prison to erect itself. His thoughts started to float further apart and his nostrils flared as his breathing increased. Heart rate rising, rubbing turns to grinding, grinding to humping. His balls softly clapping the back of his udders and his only thoughts regress to the base need to be mounted and fucked!

Leila was trying to do research and furrowed her brow at Jerrik as he knocks a stool over trying to ram it into his ass, then slides it across the floor still trying to get it inside of himself- even though an entire stool would never come even remotely close to fitting.

Leila smirked and offered him some help, motioning to Kaylie who is also extremely horny. "Seems you two mutated to have a fix for your own problems"

Jerrik snort in resentment, but then started to shuffle in pleace, needing release, then looked to Kaylie. Hearing someone address him directly snapped his conscious thought back, but the hormones distanced his thoughts so far that he immediately fell back into the void between thoughts. Rather than think of Kaylie as Leila's lover, or even a person- all he could think about is how savagely she could slam one of those meat pillars into him. When she has an orgasm; do they cum individually? Can he ride them all separately? Will the storage of cum for the first dick regenerate by the time he rotates back to it?

Kaylie just crossed her arms. "Ugh, n-no! I mean, no offense but... I... feel weird about doing it with a boys... hole. And I barely know him!"

Leila laughed. "Oh, is that all?"

She rummaged a bit to find a book of transmutation and then motioned to some of Jerrik's planters. She distilled a rubber from the plants into a floating globule and then traced the complex runic array from the book to re-forge the rubber, and she formed a sex toy in her hand, rolling it down the table for Kaylie to take!

Leila shrugged. "Given the situation we are in- I think most societal norms go out the window. What happens in these forms stays in these forms, or something like that." She motioned to the gargantuan testicles. "No one expects you to act like yourself with THOSE between your legs. Consider this a free pass to do whatever the fuck you want."

The toy is an absolutely giant bull dildo! But... rather than fake balls and sheath at the end of it, there is a cow vulva. One side is a dildo, the other side is a fleshlight! One side penetrates Jerrik, the other offers a more acceptable hole for Kaylie!

Jerrik was too horny to even consider the appropriateness of the situation and scrambled across the floor to get to the dildo, stopping so abruptly the weight of his udders swinging forward caused him to accidentally slide another foot across the floor- his hooves unable to get traction against the tile. He did several frantic hops at the table, then slammed his jaw against it and did a few more hops- trying to get off the floor to grab the toy, but he cannot lift himself because of how lopsided his body is- he can't get the toy himself.

Worried he was going to hurt himself trying to get to it, Kaylie stood fully to help. Her giant balls made a loud sweeping sound as the loose flesh dragged across the floor. When she bowed forward to get onto her feet, her tri-cock brushed the floor, connecting three glistening lines of pre to it. They are fully bovine dicks- neon pink tapered pillars, with pale violet veins throbbing toward the base where all three shared the same opening. Her sheath is not fixed to her underside however like a bull, so the weight of her cocks forces them to jut straight out from her- too heavy to hold themselves upright. Kaylie could not reach the toy without also unintentionally prodding Jerrik with her trident. He immediately froze when he felt the hot dick meat brush his flanks as one dick wedged under him slightly- beside his udder, one on his left and one on his right so Kaylie could reach far enough forward to pick up the toy for him. There was not a single semblance of a thought in his entire head- his body went full instinct mode, completely docile- stop moving, shut up, let it mount. Bull's in charge.

Jerrik's body practically vibrated in anticipation, Kaylie just sighed and slid the toy in for him since he has no hands to do it himself. Jerrik backed up to ram it in fast and deep, but because he is so lopsided he staggered back further than he intended, once again causing her dick multitude to gently prod him. Kaylie looked at the soft rubber vulva now where his anus was- the reverse side of the toy waiting for her. She sweat, breathing heavier. Kaylie glanced at Leila, but Leila was re-absorbed into her research, and that research was desperately needed to end this. Jerrik rammed himself back, staggering a bit again, parting her dicks as he stumbled closer to her. She grunt at his fumbling around and shoved him forward again by the dildo before rolling her hips forward to lift her mighty cocks again. The bouquet of dick tensed, the shafts becoming so rigid the inner cock felt like it started to outgrow the skin encasing it, causing the shafts to bend! All three dicks hugged one another, forming a tight spiral of cock flesh! A single giant phallus shaped like a screw!

Kaylie's giant hands slammed into the floor so hard on either side of Jerrik that the giant table in the middle of the room bounced a half inch off the floor from the impact! Without turning his head, he could see the spiraled horns bow low enough to be on either side of his own head. A moment later; Jerrik's vision turned blue and then white from sensory overload as the tri-dick slammed into him- wrapped in the soft rubber that is their shared toy! The dildo portion was now a sheath for a giant REAL bull dick, and slammed in and out of him so deep it dictated when he was allowed to take a breath- thrusting into him knocked the air out of his lungs!

Eventually Kaylie got tired of trying to thrust into him like this and grabbed Jerrik as she flopped back onto her ass- lifting his bovine form up like he himself was just a sex toy! Instead of thrusting into him, she lifted him up and down on her shaft- her grotesquely massive muscles allowed her to easily lift his entire body like it was nothing. When she bottomed out into him, her balls lurch forward and bounce off Jerrik's udders before she lifts him again! In this position his udders hang and push his balls back so Kaylie's shafts brush along the smooth scrotum first in order to get into his butt. Jerrik started to make breathy lowing sounds- not even aware he was doing it.

Neither of them noticed what Leila was quietly observing while they fucked at the back of the giant room. Kaylie's cum is a mutagen, as well as Jerrik's ejaculate and milk. Neither of them are mutating. They are exposed fully to one another's fluids but it isn't doing anything. Because one has Jerrik's tincture, and the other has Leila's potion. By mixing the two, it creates a stable inhibitor to the mutagen. They can mutate anyone else- but not each other.

It is a good thing they combine into a cure- because Jerrik is slathering the underside of his udders and the front of his balls in precum unable to escape the immediate area of his penis. Having his prostate absolutely smothered against Kaylie's hot shafts made him cum explosively! The cum built up in the pocket between udder and balls, inflating it like a balloon before the pressure lifted the udder enough for it all to explode out from between them like a shotgun blast! Kaylie lasted longer- but not by a lot. Her giant balls crept closer and closer, causing all the empty scrotum to scrunch up under them instead of draped out above. They hugged Jerrik's udders tightly just before she came! There was no opening in the toy on the end- but the force of the cum quickly made one to explode out into Jerrik. He was winded again and squirmed a bit from a bit of a cramping feeling! He could feel the rush of cum firing up into him, twisting and turning! She was pumping his intestines full, flowing backwards toward his stomach! Kaylie is filling his body with her cum like a jelly doughnut! His stomach started to round out and then in a sudden rush he felt... full! Like he had eaten a large meal! She actually came so hard and so much Kaylie hit his stomach! Her cum got to his stomach, backwards! He was forced to burp several times from the flow of liquid shoving out trapped air in his belly.

Her many penis were not able to hold the pressure long- so they turned flaccid very quickly once she came, and her senses snapped back as well, causing a flash of embarrassment as she pulled out and away. Jerrik shared that sentiment; immediately wondering what the hell he has done. He scolded Leila for kissing and hugging Kaylie in the research lab before and now he went and had SEX in the lab, with Leila sitting less than ten feet away! He groans from the cramped feeling- it hurts to try and bend his torso because he is so badly stuffed. Not even very much cum drips out of him because she fired it so deep into his body that it can't easily get back out. At least his own multi-pack of balls are empty and his thoughts cleared again. For a short while anyway.

After tugging idly on her giant teats the whole time she was doing her research- Leila already knew what she would do and was practically vibrating in her seat by the time she completed a dose- and then immediately drank the entire thing. Jerrik lurched forward to try and stop her but she already had it to her lips by the time he realized what she was doing! That fool! If it doesn't work this time- she has doomed them all! They will be so inhuman that no one can do research on it. Yes- someone will eventually come and do a mana purge to turn them back, BUT, they also used up all the sample mutagenic milk! So without any mutagen and no one currently transformed- their research comes to an abrupt, inconclusive end, because they have nothing left to work with! As much as he did not want to stay in this shape; Jerrik is loath to accept defeat in his research.

Kaylie looked a bit worried at her. "W-woah, wait if you..? Won't that make you even more cow?!"

Leila grinned. "It shouldn't mutate me any more than I already am, but... it will enhance what I already have, yea."

Kaylie looked down to Jerrik who was lowing and making muttering sounds. "So... why does he sound so worried?"

Leila shrugged, then shivered and quickly clutched her lower breasts as they started to firm up and swell. "P-prob...mmm, probably be-heee-cause I will grow too big on a dose that large to be able to make a reversal elixir."

Kaylie froze a moment, realizing no one was working on a cure. Jerrik grunt. They have been working on a stable mutagen- that would transform someone into cowfolk... or if you drank a large enough dose- turn you completely into a cow. A normal cow. That would not cure any mutations you may have, that isn't what it is supposed to do. It transforms you into a cow properly- but all three of them are already bovine mutants. Even if the potion did work- it won't fix that. Fixing this is an entirely separate issue. Easy to fix, yes- purge the mana from the area. You do not need to create a null mana zone, just drop the levels low enough that the spell cannot maintain itself, and then the physical mutagen becomes inert. But... they are in the Arcane University... where all the mana in the city is pumped. Unless someone else comes in here and deliberately re-wires the mana flow... the mana is never going to run out on its own.

"Wait, so then we are stuck till someone else comes to save us?!"

Leila was convulsing from surges of pleasure and just barely managed to point to a mixing and steeping unit across the room that is currently running. Jerrik sighed in relief. She is already mixing a purge elixir- it would negate excess mana from your system if you drink it, which will undo any active spells. But it isn't even done mixing yet! Damn she is impatient! And reckless as hell, transforming herself into a state of immobility before they know for sure anything even works properly! If she cannot move, and he cannot pick up the elixir- Kaylie is the only person capable of administering the cure! And she is supposed to just be a test subject!

There was not much point in complaining now though... Leila was already bloating catastrophically large! Her udders and breasts, even her nipples grew to obsurd sizes! She exploded milk across the room, destroyed the stool she was on in spite of it having metal legs, and then even destroyed the giant table under her expanding weight! Watching her was both a bit horrifying and hypnotically arousing at the same time. So much... fat, bloated flesh. Rippling, jiggling, wobbling and bouncing. Supple and smooth, rubbery and soft. Jerrik started to get a little dizzy with arousal from watching how obsessively Leila enjoyed her own flesh. She did not stop swelling till she had filled a third of the entire room. And the room is enormous- Kaylie is a literal giant and she fits just fine.

Well, it all worked out in the end. Jerrik made sure to selectively omit many of the rather... lewd details of his report, though still noted it in his research papers, since it is technically a vital detail. Leila grew obscenely giant thanks to her final potion, BUT she did not mutate. Which means the potion worked- it's a stable transformation potion, made from the mutagenic milk. While it was entirely Leila who put the final potion together- it was both Leila and Jerrik's research that ultimately made it. Leila was not even around afterwards, so Jerrik graciously accepted the accolades for them both in the meantime. Apparently Leila was still in the lab... hooked up to some equipment. In her current state- she lactates explosively, and her milk is a virtually exact copy of the original mutagen, which would be completely gone if it wasn't for her. Jerrik cannot imagine why anyone would still need the mutagen with their own research project already wrapping up. He is pretty sure she is just remaining in that form because she is crazily obsessed with it. Well... she helped him complete the research so Jerrik supposes she earned the right to milk it for all its worth.
