(F 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.

Kayliie 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.

Leila scoffed at Jerrik behind his back when he finally gave up trying to break them up. If he was REALLY smart he would have gotten Kaylie to help him with his herbs... he needs them to make his potions and she is a geomancer- she can flash-grow plants by speeding up the intake of nutrients through their roots. But nooo, he wastes his time trying to break up a perfectly sound relationship. Humph! He is just jealous he ain't getting any. Kaylie is strictly lesbian and Leila is bi... but she wouldn't touch a stuffy try-hard like Jerrik. Having Kaylie around inspires Leila's work! She loves her squishy little human marshmallow! And once this is all said and done... Leila will be able to squish-ify her own figure. With a stabilized potion you can have transformative magic in your pocket ready to go whenever you are without needing to know the spell yourself. Transformation spells cannot be done off the top of your head- you need a runic array for that normally because there is just too many parts to a living creature- it's impossible to properly visualize the entire thing.

Leila IS close to her method of fixing the potion. A spell that reverse-engineers the chaos version, so if it works correctly- the decay of the physical medium will not affect the results of the magical aspect, because the spell will be accounting for and compensate the shift. She can use its ability to self-replicate to basically re-iterate itself when something becomes misaligned.

She is so close that rather than go home at the end of the day she remained behind to tidy up... or that is what she told Jerrik anyway. Kaylie went home for the day having her own things to study for her classes, but Leila remained in her research lab. She wanted to try to get this done as soon as possible and doubted she could get to sleep with all this anticipation. She bit her lip looking at the samples in thought though. What if... she doesn't have to wait? There is one thing every version of this potion has- lactation, so regardless of what else the potion ends up doing it will ALWAYS affect the breasts. So... what if she just applied the mutagenic milk to her breasts, in a small dose? She will only give Kaylie the fixed version once she completes it buuut, she can increase her bust with the old version, if she is careful.

She made sure to put rubber gloves on to take the mutagenic milk out of storage. The tonic was topical- you apply it to the area you want to change and the effects spread from there depending on how much you use. Which means if she used her bare hands to apply it- it would also transform her hands. It was in a cryomancy stasis capsule so when she applied it she immediately recoiled and shivered. Just the few drops that ran down from where she touched to her nipples where they clung made her whole body shiver. Her jet black nipples hardened immediately and her areola became bumpy. Her breasts did not project in the slightest so their curve did nothing to stop the droplets, causing them to instead catch and bead up on her nipples which caused them to stick to its spongy surface.

Oooh, better be careful they don't fall free and touch somewhere else! It is no longer the oilier consistency of the original tonic- it is physically human milk. Just... with heavily mutagenic results. Leila cupped her breasts and rolled her hand around- the milk droplets quickly drank her warmth so it was no longer cold. It was also absorbed into her chest quite quickly. Her chest turned shiny with moisture and then returned to a matte color as it vanished into her pours! She watched her chest intently. At first it almost looked like her skin was having an allergic reaction and swelling up, but then a mild pleasure inhabited her chest and she smiled. The skin pulled taut, triggering the pleasure receptors in the gentle tugging as the fat started to blossom. Little A cup bubbles, then tiny B cup hills. Her soft brown skin started to blush. Her nipples almost felt itchy with pressure, stiff like diamonds making Leila scrunch her face up and start flicking them with her fingertips. C cup breasts now, big enough to bounce!

They seemed to stall there- and Leila got nervous when the feeling started to slowly fade again. Waaaait, wait, not yet. She dipped a fingertip into the milk so she could collect a single drop by itself and rubbed it into her newly formed cleavage, rolling her finger in a circle to mash it into her skin as quickly as possible. She cried out in surprise and then cooed in pleasure as the feeling returned fully. The super-tight feeling in her nipples started to spread around her whole tits. D cup, the rounded bottoms starting to fold over her, drooping a little but still held unusually round by how taut the skin is. G cup! Her nipples looked a bit bigger too! The feeling started to fade, but this time Leila just sighed and let it go. She is as big as Kaylie now! Just shy of DDs.

She went home that night quite content, and the weight on her chest now helped her get to sleep quickly. Leila woke up the next day having a very deep and refreshing sleep- but still aroused from last night's changes, so she wasted no time at all throwing the sheets off and rolling her night shirt up to get at the goods! Leila cups her breasts from below and rolls them up closer to her face so they stand straight out in spite of her being mostly laying down still, just propped on a pillow. They look... a little different. They haven't transformed any more, but they also don't look the same as yesterday. The blush has gone away and they hang a bit lower when let go. The skin has relaxed to fit their new size properly, so they went from extremely taut and jiggly to bouncy and soft! She can dig her fingers into their surface a bit without hurting them to feel the soft flesh squash up between her fingers. When she did though- Leila gasped in surprise as several drops of milk formed on her nipples and rolled down the underside of her breasts!

"Oooh~! Milkies!" She sat up quickly, shocked. "AH, CHANGIES!"

In a flash she had woken up enough to remember the potions effects replicate into whatever fluid it contacts- HER milk is transformative! She cups her hands to her chest below her breast to stop the milk from rolling any further down, gets up and dashes to the bathroom immediately to wash it off herself! Her breasts are starting to stand up on their own... firming up, tightening with further growth from being touched by her own milk. As soon as it exits her body it gains the ability to transform herself. While still inside of her it's included into the already active dosage and ignored, so it cannot transform her if it isn't expressed.

She breathed heavily, making stuttered cries of pleasure, unable to stop them as the changes took hold. She got it off before it was absorbed but a little bit must have still gotten back into her; it works fast. Two spots of flesh looked irritated below her breasts turning pinkish, then stiffening and turning red, then projecting out into little cylinders as they turn dark red. The coloration spreads into a circle which then starts to puff up as well, and finally the flesh turns jet back... giving her a second set of nipples and areola! Her original areola start to project outward. The weight of her milk shifts forward and the pressure relieves itself slightly- her milk is stuffing itself into the fronts of her boobs! Her breasts are developing a milk reservoir inside her areola and the base of her nipples, causing them to fatten outward! Her nipples lengthened and thickened looking like cocktail sausages! Her second set of nipples had B cup hills by the time the changes stopped.

She looked at herself in the mirror, gently rocking her chest back and forth, letting the boobs roll side to side while the rigid nipples remained frozen straight out, barely able to contain all the milk trying to rush into them. She wanted so bad to lean into the mirror and playfully bite the nipples of her reflection.

"Okay... well... this is a problem I probably should have seen coming but definitely did not."

She had nothing against lactating; Leila liked that part. What she didn't like is the fact that if she lactates she will continue to mutate uncontrollably- because this isn't the 'cured' version of the mutagen. It is harmless if she does not express it but also... her tits can only hold so much. The pressure becomes almost itchy feeling, and even brushing against her huge nipples at all will cause them to release a bit. So... she can't even get dressed without triggering it. And she cannot milk herself without touching it.

"Hmm... or maybe I can, actually."

She wandered out of the bathroom to look through her things for a moment and put on two special rings before returning to the bathroom, and putting a plug in the bathtub, to use that. Letting the mutagen run down the drain risks turning a sewer-dwelling animal into a cow-freak, so better to just not let the milk go anywhere. Leila has a LOT of piercings, because of a unique magic she had been working on, inspired by her lover's geomancy, even though Leila is not an Elementalist herself. Both rings looked identical- large and silver with a runic array around an opening at the front. But one ring had an empty socket while the other had an oval of blue amethyst. She pressed her fists together- causing the crystal oval to be shared between the two rings and completing the circuit of mana- half the runic array on either ring. Her Elemental-adjacent magic is magnetism, inducted through her many metal piercings. Milk contains a high percentage of calcium... which is a metal. Not normally magnetically reactive- it can be magnetically charged still.

She put her hand in front of her boob and motioned forward- several bubbles of milk formed on her nipple and then collected and popped off the end, floating through the air between her boob and hand. "Hah, Lactomancy! I am the Boob Wizard!"

The sphere of floating milk grew as she used magnetism to draw it out of herself without actually making contact with it. Since it floats off her- it doesn't even touch the outside of the nipple it comes out of. Once the sphere was the size of a single breast, both of hers were empty and she let it fall into the tub. The milk can be turned inert later- just remove all mana from it and the spell effects die off, then it's just normal milk.

When she returned to the university, she got glances from many people but luckily no one bold enough to prod her about it. Transformation magic IS a thing after all- there are even anthro animals walking around the university. If you know the magic to change it; you can make your own body look like whatever you want. When she got to the research lab however, Jerrik's look was an unamused scowl.

"You... did you..?"

"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."

Wow, what a killjoy. She still smirked at the sight of the lump in his crotch. Jerrik can act as uninterested as he wants- his dick doesn't lie. She can hide the fact she is technically mutated thanks to just how big her original melons ripened- her second set of breasts are too small and hidden in the shadow of the originals. The first two pull the fabric of her shirt too far out to see any hint of the second pair. The pairs are close enough together that when she lets them flop down without a prison of cloth holding them up- her lower nipples jab into the underside of her top breasts.

By the end of this day- Leila also completed her controlled potion from the milk sample! Jerrik insisted she wait and run some controlled tests before trying it on a full human, but Leila was impatient. They also did not have a very large sample pool- there is only two large cylinders worth of milk, once that runs out they have no samples of the mutagen left to research on. Of course... she is technically making more of it in her chest even now- but he doesn't need to know that part.

Jerrik insisted on staying late today to witness the administering of the potion into Kaylie. Kaylie blushed at the boobs only an inch from her face as Leila gave her the potion. Unlike the original tonic- this potion should be edible. The mutagenic milk can be drunken or applied- didn't really matter since the results were pure chaos either way. Jerrik just sat there on standby, glancing over at Kaylie occasionally to see if anything happened, but he was sitting at one of the middle stools on the very, very long old wood table while the two women were at the very end, side by side. While they waited- Leila whispered what really happened to her chest. Even Kaylie scolded her a bit for being so reckless with a potentially dangerous substance.

They started to get bored after a while and Leila sat with her back to Jerrik and had Kaylie sit in her lap and try to find her second set of nipples using only the tips of her index fingers, poking the fabric in till she felt the semi-stiff rubbery cylinders of the second set.

"That is so hot..." She glanced over her shoulder at the clock over 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."

Leila was going to invite Kaylie back to her dorm room for some fun after, but was actually a little bummed out that her restored potion didn't work, so they went back to their own dorms for the night. Leila found herself flicking her enlarged nipples when she was alone, just idly while she thinks- though scrambled the moment she felt dampness and used her magnetic magic to once again safely milk herself. If her potion failed- at least it failed in a way where Kaylie is okay. The two people who donated the mutagen were so severely mutated they couldn't even move while it was happening. But her potion ended up being so stable that it did nothing at all.

The next day Leila was mostly just absent minded, swatting her own hands away from her bosom several times, wanting to touch herself but remembering that Jerrik is in the room with her. She did not know what to do now that her version of the cure utterly failed, she kept hitting a mental wall.

Kaylie called her on her cellphone and she sighed in relief- something to break the boring silence of the research lab. "Heeyyy! How's my mashmallow?"

"U-ugh...gh-good. Ish. Good-adjacent. I am not injured at least."

"Ooookay, well that is a start. Something... up?" Jerrik could only hear one side of the conversation but glanced over in curiosity.

"What should I do if your potion started to oh I dunno... mutate me into a cow-thing?"

"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."

"Uh yea- well it definitely didn't do that."

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."

Now they had a problem of time. There is no telling when Kaylie will stop mutating and how bad it will get. It also deprived them of their only test subject. Leila prodding Jerrik on what he has got going- and his is nearly ready to test as well. He is naturally a lot more cautious than Leila so he was going to hold off on testing till he could release it in a more controlled environment- as in, cell samples in a petri dish rather than a whole ass person. But with someone already mutating on their watch- it was a sooner rather than later scenario.

"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." 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 took his own stable potion but like with Kaylie... nothing happened. He ended up leaving early and made sure to tell Leila- if he doesn't show up on time tomorrow; she knows something went wrong.

Leila glared at the remaining samples and licked her lips now that no one was in the room with her. What if she... indulged in another dose? She might actually unintentionally be on to something. She hasn't mutated wildly, yet she took the unrefined original mutagen. So what if the key to preventing mutation is just... really small doses instead of all at once? Right there in the lab she slapped on some rubber gloves and applied more mutagenic milk to all four of her breasts, humming at the feeling of finally being able to fondle her titties alone in the lab. With a smirk she tugged on a nipple and used her other hand to aim the now empty first cylinder in front of it- and refilled it with her own milk. Her milk just copied its makeup so it's basically the same thing.

Leila leaned back in the stool with her tits out looking down at them eagerly. The skin blushed and then her nipples stood achingly erect as her breasts started to swell out again- this time the bottom set growing faster than the top to try and catch up! After a few moments she felt a tingling in her spine however, and then a tugging at her tail bone as she leaned back and clapped her hands down over her lower back.

"Ack! N-no not that! I didn't put the milk there! I guess the results really are unpredictable..."

It felt sort of like someone poking it out from the inside- to stretched a bit longer in regular pulses, pushing into a chubby cone, then a noddle, then a ropy tail.

"A-aaah!" She scrunched up her face and neck from the sensation of someone tugging her ears!

Her ears started to change shape- the cartilage spreading thinner and muscles forming in the base as they became the leaf shaped ears of a cow! Her tail hit its proper length, but then started to curl a bit from internal pressure. It still did not have a tassel, and it felt like it was trying to grow larger than the skin around it would allow! An odd indentation formed down the middle of it. Her ears also felt cramped, like they were trying to grow larger but struggling. Her heart beat suddenly became thunderously loud in her ears!

She squealed and fell right off her stool onto all fours from the sensation of her breasts spiking! Her nipples were getting even longer, even fatter- and it pulled all the pleasure receptors so taut they felt too raw! Her breasts made a deep squelching sound and she very quickly arched her back as milk erupted from her teats automatically without her even touching them! She had to aim them forward to avoid the milk touching her! Her squeals of pleasure and distress raised in pitch even louder as a loud, wet peeling sound came from all around her. Or at least that is what SHE heard- it is nearly inaudible to anyone else. Her ears and tail became to split at the same time! Her ears split through what had been the swollen backs, causing a second, larger pair to split off from behind the originals and then started to grow still larger! The divot in her tail went so deep that it cut right through and from the bottom to the tip her tail split into two- and THEN her tassels grew in to complete them. She has two tails and four ears!! Well, that definitely ain't right. Her ears aren't even the from the same breed- the back two grew giant and floppy while the front were pert little leaf shaped ears. The back two are so much larger than when they flop into a full resting position they hide her original ears entirely underneath them.

Leila had to scramble to get away from the growing puddle on the floor and used her magnetic magic to move it to a disposal unit- a null magic chamber that would kill the mana inside of it, and make it inert. Too bad you can't do that with a human.

Once she emptied her milk she was able to settle her heart rate for now at least. "Okay... okay. This isn't that big of a problem. It is weird but I look cute. As long as I control my lactation it won't spread. This honestly might actually help the research... less chance of the effects going apeshit if there is only one change going on at a time."

Now all four of her breasts were the size of a medicine ball and blocked a full four or five feet of space on the floor in front of her from her field of view. They grow close enough together that her lower breasts hold her top breasts up and out, making a real shelf of tit flesh. Her nipples are as thick as shot glasses and as long as the palm of her hand. When she moves suddenly her teats actually flop around more erratically than her breasts themselves- now that the cluster of four hold one another relatively still. That goes out the window as soon as she leans forward or back, and her breasts naturally separate from either each other, or the rest of her torso to free-hang. Then they are all over the damn place.

She was glad barely anyone is around still by the time she heads home to her dorm room, because her shirt absolutely did not fit. Her top breasts hog all the fabric to themselves AND you can very clearly see the shape of her teats bent sideways around either side of her boobs- looking like a sausage stuffed into the front of her shirt! That means her second pair just bounce around under them- slightly divided thanks to the fabric taking the weight of the top pair off them. There was no rules in the school against modifying your form using magic- you can look like whatever you want. There IS rules about having your boobs flopping around in the open, and your sausage sized teats wobbling around hypnotically. She actually could modify her shirt itself to fit- but certainly doesn't know the spell off the top of her head.

Leila left when almost no one was still at the school and arrived early morning before most others even wake up, never mind head to class. Since she is co-head of the research team she has her own key to get into the lab- so even if no one else was in the school, she could still get in. Before that though- and the reason she really strained herself to wake up obscenely early... she needs to recover Kaylie. Try to sneak her out of her dorm and into the lab without being seen... if she isn't too badly mutated by now to move at all. Leila is still perfectly fine- a bit odd, but fine. But she has only been dosed with a shot-glass sized amount of the mutagenic milk, while Kaylie had the entire rest of the first cylinder.

She knocked on the door timidly, but Kaylie timidly told her she better open the door herself- at risk of ripping it off the hinges by accident. Kaylie's genitals had been completely inverted; she is full male now, technically. That did nothing to diminish her breasts however- which are actually bigger now than ever... although, they looked the same size in comparison due to her ENTIRE body enlarging. Kaylie needs to duck to fit in her own dorm room- which means she cannot fit through her own doorway. Her head brushes the roof, but she also has a gigantic twin pair of bull horns now that extend even further than that- she would skewer the people in the dorm above her if she stood up straight. When she spoke to Leila yesterday her fat had melted away and solidified as muscle, giving her an athletic build... that... seems to have just kept going last night. Now to call her muscular would be an understatement. The muscle bulk seems to have focused on her upper back and arms mostly but... oh boy. Her biceps are larger around than Leila's entire body. She also has a tail but only one normal bovine one, and her feet have devolved into hooves.

Leila's pussy quivered at the sight of her lover. "Wo-ooow... hoooboy."

"I look like a freak!"

"A hot freak."

Kaylie smirked timidly. "I guess you are bi, so you are sort of into this kinda look huh? Well... maybe I could warm up to it more if it wasn't driving me nuts. These balls won't stop... I am leaking everywheeeere. I already tried to... y'know... tame it. It didn't work. Not for very long anyway."

Her scrotum is very long, but also her balls are very large- like, small beach ball kind of large, and the scrotum long enough that they fully rest on the floor. Every so often they lift slowly then thud loudly back against the floor. Her penis is connected to the floor by a thin glistening trail of precum that seems uninterrupted- a slug-trail like path leading around the room from all the pre she has been leaking, allowing you to basically see everywhere she has gone and for how long, by how much liquid its smeared with. Her dick is as thick as a beer can at the base and almost as long as Leila is tall- a tapered neon pink pillar, a fully bovine phallus. It bobs periodically, bouncing a bit- held perfectly outright by its own weight. She seems to have a sheath but unlike an actual bull's sheath; it isn't attached to her belly so it cannot direct the shaft at all. Though... considering the mutations the original two went through, this is actually really tame. Which means Leila's potion did partially work. It worked too well at first so nothing could happen and degraded into not working at all afterwards- but in the transition between too much and too little it was able to somewhat direct the changes.

Leila offered to... ease her burden. Kaylie was not going to argue that. Her balls do not stop undulating and her prostate just keeps burbling up pre unendingly. The giant balls are pumping her full of hormones and making her horny as hell and it's been a bit since they had a romp besides. Kaylie could not mount Leila at risk of absolutely destroying her by accident, and she barely fit in the room anyway. She just flopped back on the floor, shaking the entire building a moment. Leila climbed up onto her lap and looked at all the fat veins converging on the tight groin into the base of the sheath- her pubes replaced by a mat of black fur. The penis shaft bulged abnormally. Violet colored veins visible below the surface, it seemed to be bulging out wider... her dick almost looked... muscular. It seemed to bend slightly this way and that, bulging in certain places and watching this- Leila figured out what was wrong.

"Still mutating... slowly."

"Really?"

"Are you aware of the condition known as diphallia?"

"N...no?"

"Well." She put her index on the end of the dick and started to push down. "You will be."

Kaylie groaned loudly and her shaft started to bulge on the end as Leila pushed down as if trying to shove it back in on itself. With a wet smacking sound- it bent slightly... in three different directions at the same time. Leila recognized a divot in the shaft when it throbbed- that looked like the divot forming in her tail before it split. Shoving down on her cock caused it to split into THREE separate shafts! When Leila let go, the tips flicked apart too, then with a mighty series of throbs the shafts started to split away further down, almost looking like a strange banana peeling itself. It felt sort of like someone peeling tape off your skin slowly- well, a patch of skin that didn't have hair on it. The three dicks were connected still by a web of pre on their tips. They released several short shots of pre- almost looking like she was having an orgasm except the fluid is clear instead of white. The cocks splitting is creating such a constant buzz of pleasure its making her squirm wildly. Her balls slide up her long scrotum and pat Leila on the butt, surprising her.

"T-t-too m-muuh-much c-COCK!"

"Hmmhmhm, speak for yourself. Just enough for me~"

Leila grabbed the two side-by-side upper dicks and used them as leverage to stand up and then sit back on the third dick which was below and centered between them. Because they are so long, you can actually feel the ripple of stiffness surge up their length when the muscles in their base clench. The urethra flexes tight first, then a quick wave up the meat of the shaft. Kaylie was so overloaded with hormones and pleasure she could not even think of anything to say, she just lay there breathing heavily under Leila's mercy. She is breathing so rapidly and heavy that it almost sounds like the snorts of a bull rutting.

Leila could not take the dick to the base... it's almost as tall as she is- she would have to skewer her entire body to bottom out on it. She did take the majority of it, and rocked back and forth on it, trailing her own pussy juice down the shaft, which in turn traced the soft curvature of the veins on its surface. She pistoned both the other dicks in her hands- the constant flow of pre offered more than enough lube to not need to warm up to it. Kaylie was weakly bucking her hips against Leila's weight- not even doing it on purpose, she could not help it, it was a reflex to the pleasure bombardment!

Leila occasionally bent forward to give one dick a suck and then the other, and eventually brought them closer together squeezing them to the sides of her quad-tits with her arms to give them both a tit fuck while riding the third! Leila's guts bulged every time she leaned back- causing the shaft inside of her to bend outward. Leila was absolutely loving this, her lust overriding her worry of the situation by a long shot. Her breathing did become considerably more rapid and her eyes widened as the rising pleasure was followed with more changes. Four black dots on her lower gut slowly stiffened and stuck out like moles, but continued to grow. Only now did it occur to her that Kaylie's ejaculate... also copied the potions mutagenic effects. She is getting another full dose right now by riding these behemoth prongs. Though... it is a byproduct of the partially inhibited version, so... maybe it won't be too bad? She isn't getting off till the ride is over, either way. She is too horny to stop regardless.

Some part of Leila is worried, of course, but this moment in all the frantic horny chaos is actually a calming one for her. The morning sun cast a pillar of light across the room that painted half Kaylie's face in light, making her left eye almost seem to glow. Because her tri-phallus is so enormous compared to Leila she can almost feel each individual vein bloat big and tight with each throb inside of her. That is her lover- the sexual tension in that dick meat is for Leila, that is pleasure she is giving Kaylie. Yes the transformation is chaotic and getting out of hand rather quickly, and she will have to deal with that... but right now, she is dealing with Kaylie's needs and her own pleasure at the same time- and that is an easily solved issue, and fun to boot! She loved to lean back, so the tip bends back with her, and the shaft arches forward- this stretches her pussy all the way up, and compresses the flesh into the underside of her clit, causing her pleasure to sharpen to an electrical level. Doing this would no doubt also probably hurt later, but that is for the aftermath- for now, fuck the consequences. She did not have to worry about balancing- the dick inside of her is so large and so rigid that she could let go of the other two and lean back, and the cock would hold her body up on its own. Leila had to REALLY grip the other two with her arms to hold them against the sides of her breasts to rub- when they buck; they buck almost hard enough to yank themselves out of her arms, and they are slippery as heck at this point. Every throb tugs her entire body forward slightly and jiggles her four pack of tits, making her giant teats flop around.

As the slippery and salty precum absorbs into Leila's body through her vaginal lining, her own mutations slowly progress. Her nostrils started to grow, but mostly wider rather than taller- eventually the openings fold in slightly making her nostrils sort of shaped like a J. On her lower midriff the four black teats grow longer and fatter- quickly trying to match the teats on her breasts. Even compared to the teats of an actual cow- Leila's are abnormally big. A cocktail sausage? Sure, but the size of an actual sausage? Yikes, that is friggin' big. Before they were even half the size of her breast's teats; their coloration started to fade further in around their base, connecting them as they turned the entire surrounding area matte black! When the udder started to form, it at first just looked like one singular bulge shared between the four teats, slowly lifting further forward as a giant pad of fat and nothing more.

Her pussy squelched around the giant cock rolling around as she bucks on it, and her labia became a bit longer, projecting out a bit more into a deep neon pink leaf shaped pussy... like the vulva of a bovine. However, completely unlike a cow; her clit remained visible on the surface... and as her arousal rose, so did its size! Her clit started to mutate, enlarging and lengthening- but not just the part of the clitoris that is visible on the surface, the ENTIRE thing grew, which caused her mons to suddenly bloat up giant, projecting her entire pubic mound forward in an increasingly exaggerated curve! Some of Kaylie's bull traits? But not enough to transition to an actual phallus, so it's turning into a weird amalgam. Her clit looks like a little pink marble, but then swelled to a ping-pong ball sized knot of pleasure nerves. Then it started to lengthen, pulling the glans into an increasingly cone-shaped formation, discarding its human shape. Her urethra remained exactly where it has always been, so even when the cone was a chubby four inches long, and you'd think it was a penis- it's not really a penis. Because it projects so far out, you can see when it throbs; the veins at its base where the clitoral hood hugs it pulse visibly and the entire clit bobs up and down like it is agreeing to something.

Mammary glands formed in the bubble of fat that was her proto-udder as the teats became 75% of the size of her originals. The bubble of fat suddenly had four hills, and then a definitive cleft formed between them as the muscle walls formed to help segment the four and hold their shape. Veins bulged massively around and under her belly button, projecting further out and being more numerous as they approach the base of her udder. By the time her new teats were flopping around wildly at the same size as the originals her udder segments were each bloated to the size of a honeydew melon. Her udder is now heavy enough that when she bobs down on the dick the udder lags, stretching down and then the skin tension causes it to swing back a bit between her legs- slapping her own pussy and giant clit before bouncing abruptly back into place like an elastic band!

Leila needed to get Kaylie to cum, sooooon. She wanted to enjoy this and there was no chance in hell she was stopping till this was done, but damnit- the longer this goes on the more dick juice her pussy squeezes out and drinks up to mutate! Leila's legs trembled as she hit her own massive orgasm ahead of Kaylie- it unfortunately took out the muscles in her leg and she held onto the two front dicks as her full body weight slumped back- this caused her gut to bulge forward obscenely with the enormous dong still holding her up from the inside! Oooh... that is going to ache badly later. Her ears fluttered in pleasure, but because she has four of them she was unintentionally clapping them together lightly.

Leila grunts and scrunches her face up as the cartilage in her nose pops loudly- her nose getting wider but slightly more shallow. The flesh on the end of her nose becoming redder and textured. As her nose broadened the end pushed forward, so that the bottom of her nose now faced forward and perfectly on-level with her upper lip as the same crimson skin connected the two together! Her face looks like that of a cow- but only if you view it head-on, because she doesn't actually have a muzzle. She groans and grunts with effort trying to regain her balance to work the shaft with her rippling pussy walls, not wanting to let Kaylie's pleasure wane, but having a bit of a hard time because of a pressure in her hips. When she sat firmly on the dick again her hips gave a loud, hollow crack and spread her pelvis in two chunks before the bone expanded- mending the controlled break and also reshaping it into more of a V shape! Her hip bones projected out in the back into two rather bony points, which stretched her skin a bit in between, creating a triangular shaped pocket her anus now sits in below her dancing twin-tails. As long as her thighs do not reshape into a cows, she should still be able to walk on two legs at least.

The breasts on Leila's chest are starting to enlarge again too, now they are getting so big that their weight is fighting on another- causing the bottom set to divide slightly from the weight of the top set pushing down and in, giving her upper breasts tight cleavage from the lower ones lightly pushing them together. Her areola were quite bumpy now, and she could tell by how plump they look projecting out from her boobs themselves- her milk storage is filling up. She better not start leaking while riding Kaylie or this will really spiral out of control.

"Hnnngh- ugh, ngh...nnnnnnnngh! L-lei....hah... l-lah! C-mmmm, it's- it's!" Kaylie was trying to warn Leila that she is peaking- she won't be able to hold it in much longer, but she is still so breathless, overwhelmed by the pleasure.

She did not have a dick at all a day ago, and she only had one dick instead of three before Leila arrived- so the nerves in these phallus are newborn, they have not interacted with anything before or become desensitized to anything, making them extremely sensitive. And generally nobody is supposed to have THREE dicks- she is getting the full pleasure of owning a giant sensitive cock, multiplied by three. No one's brain is built for that.

Leila could easily tell it was happening without the warning luckily- the tension keeps rising. Every time the dicks throb they soften a little less in the aftermath. Soon they are so achingly rigid that they cannot throb at all, and simply vibrate with pleasure. The urethra stretched wide around in preparation, like a cannon barrel. The biggest indicator is that it felt like someone was trying to shove Leila forward... it is Kaylie's enormous balls drawn up to her groin- shoving up against Leila's butt firmly enough to force her to lean forward a bit to make room. Leila half-sat her ass on the balls, humming in pleasure at the hot smooth flesh under her butt- the front of her body still balanced fully on the shaft. The two top dicks finally became too tight and yanked forward too hard for Leila to hold and flicked free from her, flicking a gob of pre at the back wall on either side of the window a moment before all three points of her trident erupted!

Leila had to scramble to shove her feet down into the underside base of the front dicks to stand her weight up enough to let the flow of cum out- it quickly bloated the sides of her vaginal passage like a water balloon threatening to pop her! The unending flow of pre was a pretty good indication already- when Kaylie climaxed, it did not relent quickly. Each stream fired two feet through the air before arching down and slapping the floor heavily for a full second before her tri-dick buck powerfully in a half second delay and then jet the next second-long streamer. Kaylie's chest was just heaving with her fast, heavy breaths and she squirmed as her spine was arched out in a half circle, curled from the intensity of the pleasure! Her orgasm lasted a minute and a half before tapering off quickly. Which doesn't sound like a lot, but the average human orgasm is like twenty seconds, and they ejaculate less than a single percent of what she just did from ONE dick- never mind the other two. Her cocks released the pent-up blood flow in them so quickly the weight of the penis alone yanked itself free from between Leila's legs. Kaylie only has one sheath, so all three dicks share the same home. Leila did her best to grab and slide her hands up each shaft as it softened- trying to flick off as much of the goopy cum and precum before they return to the sheath, so they don't get their house dirty. Watching the testicles release looked like someone rolling out the red carpet- except the carpet in this case is the trail of loose scrotal flesh they stretched out.

As much as she wanted to enjoy the afterglow- Leila immediately used her magnetic powers to repulse the cum from herself before too much started to absorb into her flesh. Luckily it's very thick and sticky, so it is not easily absorbed into anything. It sort of just adheres to and paints whatever it touches. Semen also contains calcium, though not nearly as much as milk, of course. Leila had to help Kaylie heave herself off the floor before the very slowly expanding layer of cum could roll back to touch her and self-mutate.

Kaylie wrapped a sheet around her chest, that hung just low enough to cover her sheath but not her trailing balls, which don't even clear the floor under her. She cannot walk without dragging her nuts on the ground- painting her scent onto everything she passes. This was the best she could do to cover herself to go out... there was no chance in hell she could wear any of her actual clothing- she is like seven times her previous size! Even Leila had a hard time shuffling her clothing back on after their romp. Her body is the same size as always but now her shirt barely fit over her top breasts- her teats bending on the fabric now caused the tips of them to pop out the bottom of the shirt! Thanks to the new black udder she could get her pants up, but could not zip them up or it would strangle the udder. She also could not pull them 100% up or the waist would rub the bottom of her two tails and irritate them quickly. That means Leila had to walk carefully because there wasn't much holding her pants up.

Kaylie can't even fit out of the door! She had to duck to get her head through, her neck, part of her shoulders and then got stuck. Leila just told her to smash through. The fact the mutagen can spread so easily without control makes her presence in the dorm a bio-hazard. Under emergency biohazardous protocols; no one is going to complain that they broke a wall. She unfortunately woke a lot of sleeping people up when she splintered the door frame and collapsed part of the surrounding wall into the hallway of the dorm. No one was awake already, so by the time they properly woke up and stuck their heads out to see what the hell happened- Kaylie and Leila were already gone.

While walking across the field back to the main building- it was baffling to believe the massive long shadow cast over and in front of her was from her lover lumbering behind her. When they arrived at the school Leila unlocked the lab and they quickly slipped inside. The lab room and its doors are huge, so even Kaylie's mini-giantess proportions still fit inside. Once in the room, she had plenty of space, even as a giant. Which is good... because she is still growing. Leila did not know if this was from exposure to their combined genital fluids, or just her original dose still slow-rolling effects, but Kaylie is still enlarging. She also started to grow fur- but it grows in rather spotty, ignoring parts of her body entirely, mostly just taking her upper body, which is also where the muscle growth hit the hardest.

It does not take long for her to start groaning from building arousal again, and then as soon as her dicks move they brush against one another which causes her erection to self-complete, and the three fat prongs start to drip on the floor again, creating another mutation hazard. Leila does her best to distract herself with the research, but she cannot help but prod her own body in arousal. It feels soooo soft and rubbery. The weight is burdensome on her but she also kind of likes it, like a constant reminder of how busty she has become. How fat and round her womanly fruit has ripened. There was also notably no Jerrik to be seen. Which means something went south, again. She tried calling his cell but he was not answering, and she is busy researching and babysitting Kaylie so going out to look for him doesn't seem like the best option, either.

Her potion sort-of worked. The main problem is there was no trigger for when it should activate and how much- the counter-measure activated immediately and in full strength, stopping any transformation from happening at all, and then because it had no physical medium to tether itself to; it just burned out entirely. If she had to guess why Jerrik's potion flopped; the decay from the decomposed potion spread to the new tincture, corrupting it, rather than the other way around. Jerrik relied too heavily on alchemy and Leila too heavily on magic... when the original tonic is both.

The doors to the lab rattled as something huge slammed into it, then they heard what sounded like an animal pawing at it. A bit leery; Leila went over and let Jerrik in... who is now so badly mutated he cannot walk on two legs. He looks like two thirds of a cow with a bit of a human sandwiched between them. And yes- a cow, not a bull. Like Kaylie his mutations ignored his gender and slapped cow traits on him in spite of him being male. Leila immediately tried to question him on what exactly happened so she could perhaps be more inspired for her next potion attempt but he only lowed at her. Oh... his voice is completely gone, he can only moo now. Welp, not getting answers from him then. He also kept rubbing his butt on things... it must be driving him nuts with hormones too, except... what the mutations did to his genitals were not kind. He could not really have sex even if he tried, at least not like how he is used to doing it.

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. Kaylie just crossed her arms.

"Ugh, n-no! I mean, no offense but... I... feel weird about doing it with a boys... hole."

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!

It 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!

Yes, having them rutting while right beside Leila is extremely distracting, but their groans and moans while they wander around and rub up against whatever they encounter wouldn't have been any better. The most disturbing part for Leila is knowing Kaylie is fucking and she isn't involved herself, but she reeaaally needs to complete this research. And they actually helped inspire her to that end. Kaylie can mutate anything with her ejaculate, including herself if she isn't careful... but she isn't mutating Jerrik. And Jerrik isn't mutating Kaylie. Because if you combine Jerrik and Leila's potions you get a working inhibitor.

After several hours of working on it, watching the effects under a microscope; Leila breathed a sigh of relief as she managed to create a working transformative agent from the mutagen. It is able to spread to other fluids still which is problematic- but that is a separate issue entirely they can work on later, and honestly a nice effect to have, in controlled situations. Rather than try to induce a full set of instructions into the person; the spell portion of the mutagen cure unscrambled the cow DNA using the human's DNA in comparison. So the cure not only used alchemy and magic- it also uses the subject themselves. Because humans and cows are both mammals, they both have two eyes four limbs and one torso and head. So if the mutagen starts to grow an arm out of your chest or ten sets of boobs the arcane portion of it jumps in and says 'hey, that's fucking wrong, actually'.

But, under a microscope with cell samples and in a human body with a complete multicellular ecosystem are two different things. Aaaand they were fresh out of test subjects for her to try the cure on. 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.

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 paused a moment when she realized what they had been working on is a version of the potion that works even beyond its own expiration date- an immortal transformation potion. That won't make them human, that makes humans into cowfolk. Making them human again would be an entirely different thing.

"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. She already made a cure elixir- all it does is normalize the mana levels in your body. Without any additive mana the spell portion of the potion fails and the transformation is negated, regardless of how mutated or normal it was. But the elixir is still being mixed, so they have to wait for the machine to finish. And in the meantime... Leila has been wanting to do this the entire time. Sooo fucking tempted to chug the entire god damned thing and bloat to obscene levels. And now that the cure is going to be made regardless of what she does... now that the situation is already devolved to chaos? Ohh yea, the last thread of restraint has snapped she wants it and she is going to take it!

She arched her spine backward dividing her tits and thrust them forward as all her giant teats erupted into several streams of milk each- her lactation going into hyperdrive. The potion is supposed to give you bovine traits, so even the fixed version if ingested in large enough amounts will make you a giant cow half. Bubbles of keratin formed off the front of her skull, pushing on the skin and quickly breaking it as she grows horns, though hers are more forward and up- Kaylie's grow out and up. Leila was a bit worried when she realized one was considerably larger than the other, and when it grew long enough she realized she has four horns, not two. But... they are lopsided. Unlike Kaylie who also has four horns... Leila grew one horn on the right and three on the left! Uh... that ain't right. That may have been a mutation that was already in her body and just hadn't progressed far enough to be noticeable. The horns grow so close together that they push against one another as they grow, causing them to diverge. They spiral around one another but do not touch each other except at the very base, creating a loose spiral of horns.

Her hands and feet started to click and deform, lengthening though the thumb and big toe on each did not stretch with the rest of the foot- distancing them as their nails turned soft. The size of her dose should turn her entirely into a feral cow... but Leila very much doubts it will. She was already mutated when she took it- the existing mutation should prevent it from turning her. Her udders grew large enough to swing freely off the front of the stool, and then forced her to grab the table edge to keep herself up. Her udders were trying to pull her off the front of the stool! Her lower breasts grew under the edge of the table and the upper grow over it. Her upper breasts keep lifting as they bloat- the tension of the fabric is grabbing onto the bloated, bumpy black areola but the boobs are outgrowing the top considerably, forcing the bottoms to billow out below the shirt and the tops to get yanked up and back, snagged in the fabric! The streams of milk from her top teats erupted sideways because the top was bending them!

Leila groaned and kneads the rubbery flesh, not able to dig into it very deep before the elasticity bounces it back into place. Her giant teats remained the same size in regards to the mammaries they are linked to, but her udders and breasts are growing themselves- so her teats grow at an equal rate. Pretty soon they are the girth of her forearm and nearly the same length too! Bigger than a huge human penis! The teats on her breasts have a mostly flat front on them, making them perfect cylinders while the teats on her udders have rounded tips, making them look softer and chubby. She kept chanting 'bigger, fatter, heavier, MORE' under her breath like she was crazed.

The wood surface of the table started to bend from the weight. Her bottom boobs took a sort of torpedo-shape to them while free hanging under her without any support. Leila had been holding the edge of the table to brace against but her expanding cleavage pinched the table so firmly between breast sets that she no longer needed to, and quickly put her hands around the lower half of the top two teats on her udders and started jacking them like she was masturbating a cock! The teats are so big she cannot close her fingers around them, and at half of them remain uncovered beyond the reach of her palm, causing the ends to flop wildly as she jerks them. Her udder flesh wobbles erratically from the movement. The front two steel legs on the stood bend, forcing her onto her deforming feet as the stood is fired out from under her, no longer usable. She accidentally shoves the gigantic table forward in the process since it's still trapped in her cleavage.

Her nails darkened and turned entirely black as they thickened and started to shove the flesh around them back, deforming the ends of her digits with the growth of tiny hoof segments. This seemed to stop there though- inhibited by the original mutagen confusing the two gene pools. The cured potion applies correct traits- it does not fix traits that are already fucked up. She has to stand on the fronts of her feet only for it to feel proper, but the flesh of her foot is still touching the ground- the hoof segments are not large enough or in the correct shape to take her weight. She still has a big toe, but it looks more like a bubble of flesh than an actual toe. Her thumbs are the same but the nail no longer has a discernable edge and is almost as soft as the skin around it- it is also too far back from her fingers for her to hold anything properly. Her middle and ring finger are giant compared to the other two- but they are still all fully functional digits.

She was grunting like a bull in heat from the amount of effort it is taking to remain standing. The table is holding half her breasts up for her and taking almost all the weight from her upper body- but her udders alone are so immensely heavy that they are threatening to blow out her kneecaps and fold her legs. The bottoms of the udders swung like a wrecking ball past her knees, then her shins. Her monstrously engorged teats brushed the floor, then bent against it, then started to get smothered as udder flesh brushed the floor, and then rested on it, and then spread out against it! Now her legs felt fine... because her udder was fully resting on the floor- having exceeded the length of her legs to hold itself up. Her thighs fit comfortably into the cleft between the front and back udder segments, and once it started to force her legs wider, she thrust her hips forward and up and then sat down- onto her own udder! She lifted her legs up onto her udder and sat perched on her own giant bloated flesh sphere like it was a bean bag chair! Putting her weight on it caused her teats to stand out straight in spite of their monstrous size and absolutely erupt with milk- streaming hard enough out of her flesh that it sprayed several inches out before arching down to the floor!

The udder connects to her upper crotch, but is so large it easily fits between her legs... but that means the trailing flesh between those two points is pulled taut over her pussy, with her deformed monster clit jutting into the supple, smooth flesh. She held the top two teats still, only now held them like handles to keep her balance while riding the giant bubble of amorphous flesh and started bouncing and grinding her cunt into her own udder to get off! Her twin tails flicked around wildly behind her and her twin sets of ears unintentionally flicked together as if clapping along to the rhythm of her arousal.

She arched her spine back, which caused her upper breasts to draw slightly further back than the lower, which caused their weight to position them in reverse from before- the top two trying to roll out while the bottom two were pushed tighter together. As immense as her udders became- her breasts were already larger to begin with and hit even more obscene sizes first. In spite of being held up off the ground by her udder- her bottom breasts still rested on the floor in front of her too. Nipples the girth of a mini traffic cone and length of an entire forearm. You couldn't stuff that into your mouth if you tried and you'd drown on the amount of milk it produced even if you did. Her upper breasts bent the table, but her lower breasts shoved off the floor expanding up into the bottom of the table... starting to bend it UP. The bottom breasts pushed up in the middle and the upper breasts down on the sides- and between them they snapped the table in half! Without the table top dividing them, the size and weight of her upper breasts caused them to bounce on the tops of the lower ones and then roll off the sides- now all four rest on the floor in a row, with the upper two taking the outermost positions, squashing the lower two together.

Leila no longer needs to try and balance herself precariously on her amorphous flesh- her breasts will not allow her to fall easily in any direction; they anchor her in place! Bigger, rounder, fatter. With her weight compressing them her udders get veinier and rounder, wobbling and bloating as they lift her higher off the floor! Her breasts wobble and roll over more and more of the floor- filling more of the room with her hot, obscene mass. The soft brown flesh undulating as it expands, rippling like molten chocolate, the white of her milk a stark contrast from the jet black teats it erupts from. Her pussy juice drips down the back cleft of her udder as she continues to grind against it. Her growth so arousing to her that she did not care who was watching, what she looked like, who might walk in to see this. She just ground her mutant clit into the flesh harder and faster, causing her to bounce on the elastic surface of the huge udders.

She hit at least four orgasms riding her udder- her clit getting more raw with each one, causing the pleasure to almost overlap into painful levels, arching her back at the fourth one as her entire body vibrated from the force, sending little ripples down the length of all her mammaries. She stood straight so abruptly she caused her breasts to roll around, causing the upper two to sort of fit into a pocket between the lower breasts and her udders, beside and somewhat between them. This also locked her torso upright- she cannot bow even slightly forward anymore because its physically impossible for her to move tits of that size, so now that they are all resting fully- she is stuck in that position, between a wall and a floor of tit flesh. Each udder segment twice the size of her entire body- each breast half again as big as each udder segment, and capped with teats the size of fire hydrants. The milk flow finally slowed to a stop. She is still very full of milk, but the pressure isn't enough for it to escape on its own and she sure as hell can't reach any of her teats now.

She just hummed in pleasure, delirious with arousal still, pushing herself forward and down deeper into her own flesh, giggling like a drunk at the feeling. Well... her dose finally finished, this was as big as she can get without chugging another one, and she is in no shape to mix up another batch. The room they are in is gargantuan and she managed to take up a third of it entirely with her own body. But you have to wake up eventually from even the sweetest dream.

Jerrik did not have hands to do anything, and could not stand up. Leila is clearly immobile- her body is so heavy a freighter ship could use her as an anchor. As big and mutated as Kaylie is... she is by far the most mobile of the three. She had to squirm past all of Leila's bloated flesh to get at the machine once it dinged- indicating the mixing was done. Once the bloated chocolate flesh brushed against the exposed tips of Kaylie's multi-dick, she froze and breathed out a stuttered sigh, fighting her instinct to grab the giant tit and start thrusting. She managed to grab the potions and give them to Jerrik and herself. The speed at which they returned to normal was almost comical. Their transformed state was maintained by magic- the null elixir removed the mana powering it, causing the changed portion of their body to look like it was vaporized. Kaylie stumbled out from her transformed state so quickly she could not stop herself and ran into the side of half the broken table, winding herself. Jerrik returned to normal so his body could no longer stand properly on all fours suddenly, causing him to abruptly fall over onto his side and then scrambled to cup his hands over his junk to hide it from the women. All three of them were naked in a ruined lab with cum, precum, pussy juice and several gallons worth of milk sprayed across basically every single item in the entire room. Leila was able to use papers they no longer needed and the sheet Kaylie came wrapped in so transmute some clothing for the pair.

Oh, but Leila? Yea, she changed back... a week later. She used the original mutagenic milk, remember? They were fresh out of samples so she had them rig up some auto-milkers, so she could provide them more samples for any future research they wanted to do on it. You know, for science, or whatever. Definitely professional.
