This is a commission for fairy-of-fetishes; you can check out both his DA and FA pages for more info.

He contacted me at the beginning of the year for a commission; for some reason he thought I would be good at making a story involving cows, lactation and transformation. Go figure.

This was easily the longest single story I've ever posted, and thankfully the commissioner enjoyed the end result. Let me know if you guys feel the same way; let me know what you think.

From the experimentation journal of Amaya:

Day 1: Today I'm beginning my work for Mama's Milk, one of the lead dairy providers in the country. Looking for a leg up on their competition, they're looking for ways to increase the production rate of their cows, without causing physical or psychological damage to the animals and without causing them to produce strange chemicals in their milk as a by product of any modifications. After reviewing the guidelines and limits, I have applied and been accepted as one of the researchers working on this project. The six month deadline for results is tight, but I see it more as a challenge than a hindrance.

How little Amaya knew at the time. The amount of legal mumbo-jumbo and restrictions imposed on the experiments by the company's lawyers was making her work much harder than normal. Genius though she was, Amaya wasn't sure if the reason she couldn't understand most legal paperwork involved with her experiments was that lawyers were that much smarter than her, or they were just really good at covering their stupidity by using fancy words, loopholes and legal double speak. She'd only given the restrictions a cursory review before she signed on for the project, not realizing what she believed to be a standard research agreement was actually a set of legal shackles, tying her hands and turning what had started as an interesting mental exercise into a major chore.

One of the main culprits for her lack of progress was a line she'd missed the first time reading the experiment proposal. She knew that the ultimate result was to create a formula that would harmlessly increase milk production in cows; that was the stated goal of the project, after all. What caught her off guard was that she wasn't going to be provided any specimens for her to test formulas on; they would only provide her one cow to show her results on when she was done. If her experiment didn't produce the desired results on that lone cow, she was done with the project. No reimbursement for her time or supplies, no second chances; nothing. Amaya had to obtain perfection, without any test subjects being providing to her by Mama's Milk. While she could make formulas and theories all day long, not being able to apply any of those results on a subject was a severe hindrance.

Still, Amaya was nothing if not determined. Mama's milk promised full reimbursement for all expenses if her experiment was successful, in addition to a hefty bonus. Tying her long brown hair back and donning a pair of safety goggles to protect her beautiful brown eyes, she quickly got to work on creating an initial formula. She'd just worry about securing her own test subjects later.

Day 25; I have produced a prototype formula. Experiment restrictions prevent me from testing this formula on an actual cow, and I'm not entirely confident that this will live up to either the standards of the experiment or my own. However, while experiment guidelines do not provide for a subject, there are no restrictions about obtaining a specimen on my own. With that in mind, I have obtained the agreement of a local farmer not involved with Mama's to use one of his cows to test the prototype formula on for a small fee.

Ready to test her first formula, Amaya got in touch with a local farmer for assistance in carrying out an experiment. She asked the farmer for his least productive cow, figuring that any results from her formula would show more readily on a less productive cow, and was introduced to Bessie. Bessie's production had gone down rapidly as she'd gotten older, which was not unexpected as a cow grew older. She had once been the greatest producer on the farm, however, and had gone from being the star of the herd to his lowest performer in the space of a few months. Old Farmer McDonald(which was apparently his full legal name) was willing to try almost anything to get his former best cow back in prime form, and welcomed Amaya to his farm with open arms.

Most animals are not very appreciative of being experimented on, and Amaya was initially concerned that Bessie would not take well to her. Much to her relief, Bessie turned out to be one of her best experiment subjects ever. She started off by rubbing her head against Amaya and mooing happily when they were first introduced, seemingly very trusting of someone who was a complete stranger to her. She was calm, friendly and offered no resistance when the prototype formula was injected into her.

There was no immediate reaction after the injection, which did not bode well for her formula. Amaya had designed her formula to begin causing an increase in lactation within minutes, and Bessie was showing no signs of any sort of reaction. She prayed that she had just made a miscalculation about the amount of time needed for the formula to take effect as she stayed to observe Bessie.

Nearly half an hour later, Bessie still seemed completely unaffected by the formula, and had decided to go munch on some nearby hay. Amaya had already written off her prototype formula as a complete failure and had begun to pack up her equipment, preparing to go back to the lab and start from scratch. Just as she was about to leave, however, she noticed a small trickle of white dripping from Bessie's udders. She quickly got her camera back out to record the results, believing she might have just achieved success after all.

That hope was quickly quashed as Bessie suddenly started to tremor and shake like she was experiencing her own personal earthquake. The milk continued to flow from her udders, the rate and pace of leakage quickly becoming apparent to even the most casual observer. The same observers would have also noticed that her subject was not appreciative of the results. Bessie started to panic and run around the field, leaving a river of white behind her as she stampeded about uncontrollably. By this point Old Farmer McDonald had come out to see what all the excitement was about, and was quickly concerned by what he saw. Amaya continued to record the panicked cow and her pursuing owner, watching him slip more than once in the milky trail she was leaving behind her. The flow finally stopped after nearly five minutes of this, but it took twice as long for Bessie's owner to get a hold of her and calm her down.

Bessie wanted nothing to do with Amaya after that, shrinking away from the scientist when she tried to approach again. Old Farmer McDonald wasn't anymore pleased with her than Bessie, demanding that she leave his property immediately. He promised to document what happened to his cow as a result of Amaya's formula as part of their previous agreement, but Amaya felt it was probably so he could get restitution for damages in a future lawsuit instead of following scientific procedure.

Follow up reports from Old Farmer McDonald stated that Bessie avoided anyone human for the next couple of days, and it was almost a week before she showed any real need to be milked again. Despite the seemingly impressive amount of milk production Bessie displayed during her panicked stampeding, the overall amount of milk she produced was estimated to be no higher than a normal week's worth of production from her at her current rate. There seemed to be no permanent damages to Bessie, and Old Farmer McDonald promised to not pursue legal action against Amaya. He also promised to have her arrested if she came anywhere near his farm ever again, dashing any hopes of a second try with her test subject.

Taking Old Farmer McDonald's reports and adding it with her own observations, Amaya concluded that her formula had in fact not increased Bessie's overall milk production as it was intended to; it just caused all of her production to occur at one time. While she could see some benefit of the nearly instantaneous milk extraction, she had failed to achieve the intended goal of the project. That and the psychological damage she might have inflicted on poor Bessie gave Amaya little choice but to write off her first formula as a complete and udder(pun intended) disaster.

Day 60: After many weeks of trial and error, I have synthesized a new formula that I ready to apply to a living subject. After the incident with Bessie, however, word has spread throughout the farming community. My attempts to secure a second bovine specimen for experimentation have been met with distrust, distain and outright threats of physical violence or legal actions. Experimentation is at a stand still until I can find a new test subject.

Amaya was not in a good place either emotionally or with her experiment. She had a new formula she was ready to test at this point in time, but was spending all her time on the phone trying and failing to secure a second test subject. It seemed like she was going to have nothing to show for her time and effort other than a video that would make her a ViewTube sensation and nothing more. She continued to tinker and work at her formula in between wasted phone calls, but she simply going through the motions. It was only her pride as a top scientist and researcher that kept her from simply dropping the project altogether.

Day 67: I had hit my lowest emotional point of the project. Still unable to obtain another specimen for experimentation, I had begun to think I would simply have no choice but to halt all experimentation and drop out. In fact, I was reaching for the phone to tender my resignation from the project when Rebecca called. She's a dear friend, and it had been forever since we'd seen each other. Desperate for a break from my failure in the lab, I accepted her invitation to lunch.

Although not on the same intelligence level as Amaya, Rebecca was still a bright young woman, and was sympathetic and understanding to Amaya's current predicament. She listened intently to the results of her experiment so far, and her frustration at how stuck she was at this point. Rebecca couldn't offer much in the way of scientific advice or suggestions, but it was still good to just spend time with her friend and tell her story. Rebecca was particularly amused with Amaya's farm experience, giggling almost uncontrollably as she listened to Bessie's reaction to the initial formula.

"Sorry to hear your research isn't going so well. What happened on the farm may have been unintentional and a failure from a scientific view, but I think some people might have paid to see Bessie's reaction if that's any consolation." Rebecca managed to get out after she finally managed to stop laughing, wiping the tears of laughter from her grey eyes. "I wish I could help you out somehow, but this stuff is way over my head."

"I know, but I appreciate the offer." Amaya sighed as she looked over her friend. Rebecca was a bright girl, but definitely not the scientific type. Besides, with her experiment pretty much dead in the water, the only real help Rebecca could provide was if she was willing to be a test subject for her formula.

Amaya laughed a little to herself as she imagined what would have happened if Rebecca was in fact a big cow she could experiment on. She pictured a cow like Bessie, but with Rebecca's black hair wandering around a field, chewing hay and just enjoying a happy, simple life. She would trust Amaya, and would have no problem with her friend coming up to her and injecting her. Good friends help each other out, after all, and Rebecca would be willing to endure almost anything for her friend, even if that meant being injected with experimental formulas and allowing every aspect of herself to be measured and observed.

Get a grip on yourself!, Amaya thought as she tried to focus back on reality. The formula was supposed to work on cows, not people. Even if Rebecca was really willing to do ANYTHING to help, the formula would do nothing to her in its current state. Sure, it would be easy enough to make a couple of modifications so it might have some sort of effect on people, but while she was a bit on the pudgy side, no one would mistake Rebecca for a cow. Besides, the closest thing to udders Rebecca has was her breasts. It's not like they could lact...ate...

Wait, could she really do that to another person, much less her own friend? No, that was just crazy! Still, Rebecca did say she would be willing to help...

"Um, Amaya?" Rebecca looked a little confused and nervous as her friend stared with a laser-like intensity at her chest. "Is something wrong?"

Amaya didn't respond as she continued to ponder her idea. Yes, it was more than a little crazy, and yes, it wouldn't be the easiest thing in the world for her to do. Still, wit Amaya was about ready to try almost anything at this point. Ideas for how to modify her formula were already forming in her brain as she turned her attention back to Rebecca's face.

"Rebecca; this might sound a little crazy, but can I ask you a favor? A really, really big favor?" Rebecca tilted her head as Amaya gave her a brief outline of what she needed from her friend.

"W-What?!" Rebecca was stunned by her friend's proposal,. Amaya was suggesting that she could modify her formula to be useable on humans, and inject it into Rebecca. Amaya was much more familiar with human biology than bovine; if she could create a formula that would cause humans to lactate, she was certain she would have a much easier time replicating the same results with a bovine specimen. While she could probably get a few volunteer test subjects through her contacts in the scientific community, finding them, documenting their complete medical histories and negotiating the terms for their volunteer work would take too much time, and time was the one thing Amaya could not afford to spare if she was to meet the deadline.

Rebecca's initial reaction to was to ask for the check immediately so she could pay for her meal and get away from her insane friend as quickly as possible. She began to worry her stress and lack of progress in the experiment had turned Amaya into a mad scientist straight out of some horror movie, and had driven her to desperate lengths to complete her project. Rebecca was beginning to picture Amaya's lab as an old fashioned castle deep in the woods, seeing the whole scene in black and white like she was watching an old fashioned movie. She imagined being strapped down to a table by an Amaya with crazy hair, cackling evilly as a bolt of lightning streaked through a window behind her while she attached electrodes and a large metal hat atop her head. She attached connecting equipment to a nearby cow, who despite being trapped indoors and surrounded by strange equipment seemed pretty calm about the whole scenario. Suddenly a dome in the roof above them opened, and a lightning rod rose up into the dark night sky...

Rebecca dismissed that scenario from her mind, but couldn't help but glance nervously toward the exit again. She was more than a little frightened about where this could go, but she also Amaya wouldn't ask such a favor of her unless she had not other options. Her friend promised that anything her experiment might do to Rebecca would be completely reversible, and that Amaya would be indebted to her for life. After a little more nervous teetering, and with a slightly audible gulp, Rebecca agreed to help her friend with her project.

Day 70: I will begin experimentation with my newest test subject, now that all the appropriate research related paperwork has been signed. The subject is 5'2" tall, black hair, grey eyes, weighing roughly 155lbs. She has no known health issues, and while the subject is a personal friend, the entire experiment will be recorded to assure the objectivity of the study.

While she understood and accepted her friend's reasoning for her actions, that didn't make it much easier when she had to strip and allow Amaya to take pictures of her completely nude body before attaching electrodes from a nearby heart monitor to her chest. It was another necessary evil of the study, though Rebecca did make a (mostly) joking promise to Amaya that she'd beat her senseless if those pictures ever found their way on the internet. With both parties fully aware of their responsibilities to the study and each other, Amaya administered her newest formula into Rebecca.

As it had with Bessie, the formula seemed to show no initial reaction on Rebecca. Amaya stressed the importance of remaining patient, continuing to record her Rebecca as she rubbed her hands against her arms(while still being careful not to accidently knock off the electrodes attached to her) in an attempt to stay warm against the sudden coldness that had crept into her body. Doing so blocked the camera's view of her chest, and Amaya had to ask her to keep her hands down at her side during the recording.

"But I'm freezing! Couldn't you turn up the heat a bit?" Rebecca asked as she slowly pulled her hands down. "I mean, seriously; look at me! Even my nipples are as ha- OH GOD!"

The reason for Rebecca's startled reaction was quickly clear; what Rebecca had believed to be her body's reaction to the cold was actually being caused by the formula that was now in her body. Amaya initially thought the large, swollen nipple was just a reaction Rebecca's body was having to the cold, but as the two women watched it became apparent they were slowly growing larger The area of areola at the base of her breast wasn't spared from the changes and was slowly expanding, beginning to take up the entire front section of her chest.

"Oh geez; this feels really weird!" Rebecca continued to watch with mix of surprise and shock, afraid to touch her chest as it continued to change. The nipple's continued to swell, not only taking up more and more of her chest but pushing out further and further from it as well. Each rapid, panicked breath seemed to make them push out a little further, the pointed tips now over an inch from her chest and continued to grow longer as the two women watched.

This reaction was not entirely unanticipated by Amaya, who hurriedly added to her notes as the camera continued to record. She was concerned for her friend, especially since she was the one responsible for causing these changes to occur, but following proper procedure would be the best way to make sure everything went smoothly and result in getting her friend back to normal as soon as possible. Allowing emotion to get in the way would only make things worse.

Despite her outward appearance of calmness, any experienced scientist like Amaya would get a little concerned when Rebecca mentioned her chest was starting to feel heavier. Her first concerns that Rebecca was having a heart attack were dismissed when a glance at the monitor only showed a slightly increased heart rate, more likely a sign of growing anxiety and stress than an impending heart attack. She assured Rebecca that she was fine, but she was at a loss to explain the symptoms her friend was describing at first. It didn't take too long, however, before she was able to pinpoint exactly what was happening.

"Subject is experiencing increased growth not just in the aerola, but the entire mammary region of her body." Rebecca confirmed that with a nod as she hefted up her gradually growing chest. The already sizeable orbs felt as if someone was slowly forcing air into them, causing them to slowly swell and take up more and more space. The nipples continued to expand at an even quicker pace than the rest of her chest as Rebecca struggled to lift them up and keep from being pulled forward off her chair by them.

"The subject is also getting a bit nervous!" Rebecca tried her best to remain calm and not freak out as her breasts now rested atop her belly, but it was taking every ounce of self control she had not to panic as the sheer size and weight forced to lean forward slightly. They were easily the size of watermelons, with nipples that were becoming impossible to fully cover with her hands no matter how hard she tried. "How far is this going to go?!"

Luckily for Rebecca, by the time the words were out of her mouth the growth had already started to taper off. After a few more moments of mammary maturation, Amaya couldn't see anymore growth, and Rebecca confirmed that she didn't feel cold like she did when the formula started to take effect. It appeared that her body had returned to functioning normally.

Amaya quickly confirmed with Rebecca that, other than the fact that her breasts were now hanging down over her belly and hips, she felt fine. While movement would still be difficult, at the very least she wasn't in danger of being smothered by her own chest. She still wasn't exactly thrilled with having nipples about the same size and length at her forearm or breasts were bigger than some boulders, but other than that she seemed perfectly healthy.

"Hmm..." Amaya shook her head as she took a full assessment of all of Rebecca's changes. "This is not good..."

"Don't worry; I feel just fine." Rebecca tried to reassure her friend as she looked herself over. "I mean, none of my clothes are going to fit, and I can't even see my feet anymore, but I don't think that formula hurt me. You said you can undo this, right?"

"What? Oh, yes, I can undo it, but that's not what I was concerned about." Rebecca tilted her head in confusion as Amaya suddenly grabbed one of her breasts roughly. Rebecca gasped and blushed as Amaya started to squeeze and grip her bountiful breast.

"H-Hey!" Rebecca blushed, her nipple starting to stiffen from the rough treatment. She tried to reach out and swat her friend away, but with her breasts being so huge she couldn't reach her properly. "Amaya, what the hell are you doing?!"

"Testing a theory." Rebecca blushed deepened as Amaya gripped one of her nipples, squeezing and tugging on it. Rebecca had to admit it felt kind of good in a weird way, but her embarrassment at the fact that all of this was being recorded and the rough way she was being treated kept her from taking much pleasure in it. Rebecca had to settle for swallowing her nerves and waiting for her friend to finish up, which thankfully Amaya did soon after. "Exactly what I was afraid of..."

"Afraid of?" Rebecca tried to keep her embarrassment off her face as Amaya took her hands off her and immediately went back to her notes. "What exactly were you afraid of?"

"After what happened with Bessie, I altered my formula a bit. Specifically, I reduced the lactation reaction and instead focused on increasing the subject's capacity to store and control the rate of milk output." Amaya shook her head as she continued to make notes. "Unfortunately, I believe I overcompensated for my previous error, and made another in its place."

"Do you mean the fact that no bra in the world is going to fit me now?" Rebecca asked.

"No. Well, yes, that as well." Amaya corrected herself. "What I meant is that you're not lactating at all. You don't feel any milk in your chest, correct?"

"Well, no..." Rebecca gently prodded her chest, making her breast quiver and jiggle a little as she gently poked it. "I mean, my chest looks like a giant set of hot air balloons, but it's all just me. No liquid, no nothing inside them."

"Exactly what I was afraid of." Amaya sighed as she set down her pen and notebook. "The end results are different, but ultimately this formula is as much of a dud as the first one."

"Well, I'm sorry it's not working out like you planned, and I don't wish to sound unsympathetic in your time of stress, but..." Rebecca pointed toward her chest as best as she could, trying to get Amaya attention off her own problems and back to hers, "... can you please undo this now?"

"Huh? Oh! Right, sorry!" Amaya blushed as it suddenly dawned on her what her friend must have been going through. Retrieving a fresh syringe and needle, she drew a formula from another vial and quickly administered it into her friend. "Now, this serum will speed up your body's metabolism temporarily and cause it to focus on drawing all of its nutrients from the increased fat in your chest. It's perfectly safe, but even with the temporarily increased metabolic rate, it'll be a good eight hours or so before you're back to normal."

"Eight Hours?!" Rebecca sighed, feeling almost as deflated as her chest was inflated. "Well, that's just great. Could you at least get me a blanket or something so I don't freeze to death?"

Amaya spent the rest of the day getting Rebecca as comfortable as possible, keeping her warm and bringing in a TV to pass the time. Rebecca was finally able to sit upright again a few hours in as inches were slowly burned off her chest, and after eight hours she was back to her normal self. Unfortunately for Amaya, Rebecca declined to help her with any further experimentation, forcing Amaya to have to search for another test subject while she worked on a new version of her formula.

Day 84: The last two weeks have been spent modifying and reworking my formula, which is now in its third form. I have still been unable to obtain another bovine specimen for experimentation, but I have acquired another human volunteer, another friend named Sandra. She's 22, 5'3" and roughly 130 lbs. As with Rebecca, all results of the experiment will be recorded to assure safety and objectivity. The new formula and its results will be applied later today.

"Rebecca told me about what happened with her when you injected your formula into her." Sandra blushed a little at the camera as Amaya set it up. She was just as naked as Rebecca was for her experiment, and even more shy about being recorded. She held her arms crossed in front of her chest as she pushed away a stray black hair from her head, her sapphire blue eyes staring nervously at the camera as she watched Amaya make her preparations.

"Don't worry; I've made multiple modifications to that old formula. Your breasts shouldn't be growing to the same size as hers." Amaya assured her as she started recording.

"Alright..." Sandra pushed back a jet black hair from her eye as Amaya prepared her latest formula. Keeping one arm over her chest, Sandra offered her the other arm for injection. She was never the biggest fan of needles, looking away and wincing as Amaya injected her.

"It's in; we should see results in a couple of minutes." Amaya quickly applied a bandage to the injection site, then stepped out of view of the camera to begin recording the results. "Thank you again for doing this, Sandra. You don't know how much this means to me.

"Sure; anything for a friend." Sandra smiled softly and tried to put on her bravest face and not fidget too much in front of the camera. "So, what exactly do you need me to do?"

"Just let me know if you feel anything happening." Amaya took a quick glance at the nearby monitors, keeping a close eye on Sandra's vitals. "I've made quite a few adjustments to the formula, so I'm hoping for a more controlled reaction than what happened with Rebecca."

Sandra had no argument with that. She had heard what happened with Rebecca, and was not keen to have a repeat performance with her own experiment. Already she was feeling a slight tingling sensation in her chest, very similar to the one Rebecca described when her body began to change.

At first she thought it was simply due to her increased breathing rate, but Amaya soon noted that Sandra's crossed arms were beginning to conceal less and less of her chest as time passed. Sandra had very few revealing outfits that showed off her body, but when she did wear something a little more exotic, she always turned heads with DD chest. She would start turning a lot more heads now with her slowly growing bust, more and more tissue spilling out and over her crossed arms as she struggled to cover herself in front of the camera.

"Ooh..." Sandra blushed as she gave up trying to cover her entire chest, instead settling for just trying to cover her nipples. Even that was becoming a struggle, her areola's starting to becoming bigger than her small hands could cover. "H-How long is this supposed to go on?"

"I've turned down the growth factors a bit, so hopefully not too much longer." Amaya breathed a little sigh of relief as she continued to monitor Sandra's progress. She was starting to become worried when the bottoms of her breasts were starting to meet the tops of her abdomen, but it seemed to be progressing no further than there. "Look, I think it's already starti-"

"OH!" Amaya's relief was short lived at Sandra's startled cry. She watched as Sandra pulled her hands off her nipples, looking confused and slightly alarmed when she saw the small puddle of liquid pooling in the palms of her hands. "Is this?..."

"Milk!" Amaya tried and failed to fully contain her enthusiasm at seeing the small white pools in her friend's hands. Amaya quickly grabbed a nearby specimen cup and held it to one of her subject's nipple. With a little help(and a whole lot of blushing), Sandra gently massaged her own breast, gasping a little at the feeling of liquid coming out of one of the most sensitive parts of her body.

. Sandra tried her best to sit and wait patiently, the camera continue to record her as she wobbled a little while she tried to adjust to her new size. She really wished Amaya would hurry as she took the sample over to a nearby terminal, testing the nutritional values and make sure there wasn't anything harmful in the milk. Getting used to the new dimensions of her chest was something of an adjustment, but that was bearable. What wasn't as tolerable was the itch she was experiencing, right above her clit. She didn't want to start probing around down there while being recorded, but it was really starting to bother her. She squirmed a little in her chair, her pendulous breasts exaggerating her slight movements and almost threatening to knock her off the chair.

"Alright; it looks like everything's alright with your milk." Amaya smiled as her computer confirmed that her friend was producing normal, human breast milk. "Do you mind if I get a few more samples?"

"S-Sure, but please hurry." Amaya was confused by Sandra's worried tone, turning to see Sandra's crossed legs blocking the area that was bothering her. "I think there's some kind of inflammation... you know, down there..."

Amaya tilted her head, asking Sandra to show her what she meant. After getting a reassurance that her privacy would be maintained, Sandra slowly opened her legs to allow Amaya to examine her. Her breasts blocked a clear view of the researcher's face as she knelt down to examine the affected area, but the sharp gasp that came from Amaya was as clear as day to her ears.

"What? What is it?" Sandra asked as Amaya slowly rose to her feet, her concerned face starting to match the one's on Amaya's as she felt the irritation continued to grow larger and more intense.

"U-Um..." Amaya gulped nervously, not sure how exactly to word what she saw. "You have... udders..."

"What?" Sandra glanced down at her chest dripping nipples. "I mean, my breasts are kinda big, but I don't think you could really call them udders, either."

"I wasn't talking about your chest..." Quickly glancing around the lab, Amaya ran to and retrieved a large pan usually used to hold specimen samples. It had a large, flat surface that was good for reflecting, and after fiddling with it a little bit trying to fine the right angle, Amaya was able to show Sandra what she was referring to.

Sandra couldn't tell exactly what she was seeing reflected in that pan at first. Placed just below her belly, at first all she could see was a rounded, pinkish bulge about midway between her the bottom of her belly and clit. Even though it itched like crazy, it didn't look red and inflamed like an infection normally would. Actually, she thought as she continued to watch it inflate, it kinda look like a large nipple. Unlike the ones on her chest, though, this one seemed to have four tapered points, roughly equally spaced apart. She tentatively touched one of them, letting out a sharp gasp when a shiver rocked her body and a familiar substance filled her hand.

"AHH!" Sandra couldn't hold back a little scream as she sudden realized what she was poking and prodding. Amaya watched Sandra's heart rate sky rocket as her udder started to leak on the floor, filling Sandra with even more milk and some panic as she realized what was happening to her. "AMAYA! DO SOMETHING!"

"I will, I will!" Amaya gulped as she quickly backed away from her friend's new udder, grabbing for the reversal serum that she'd kept nearby as she apologized. "I'm sorry! I had modified my formula to alter some hormones in your body so that it would produce milk in a similar fashion to a cow. I didn't imagine it would actually give you an udder, though!"

Amaya had a classmate back in college who would blow up the latex gloves they used in lab classes like a balloon. She recalled the way the glove would blow up, then deflate slightly as her classmate slowly paused for more air before making it even larger than before. If the gloves they had used had one less finger and were the same pink color as Sandra's udder's, her classmate's antics would have been a near perfect reflection of what was happening to Sandra. Amaya tried hard to think about the one time that same classmate blew a glove up so much it exploded as the udder started to reach basketball size while she struggled to prepare the serum.

Much to the relief of everyone involved, the udder seemed content to grow no more past that point. A part of Amaya wanted to see how functional that udder was as small drops of white liquid formed at the tips of the teats, but one look at Sandra's panicked face told her that idea would not go over very well with her friend. Amaya made the last of her notes and quickly administered the reversing serum. Sandra finally started to settle down, her enthusiasm to continue the project deflating much more rapidly than her breasts and udders as Amaya tried to console her.

The more potent formula took longer to reverse than the one given to Rebecca, and it was nearly half a day before Sandra was back to her original self. Amaya thanked her for her help before sending her on her way, knowing better than to even think about asking Sandra for a follow-up experiment. She had succeeding in actually producing a lactating subject this time, but the addition of an udder was not what she anticipated. Mama's Milk's executives probably wouldn't appreciate her giving their cows extra appendages, so it was back to the drawing board. The costs of this experiment were becoming astronomical in both time and expenses, and as she watches Sandra hurriedly make her exit, Amaya couldn't help but wonder if it was going to start costing her friends, as well.

Day 160: The deadline is rapidly approaching for the end of the experiment, and I feel like the formula is nearly perfect. I've gathered enough data from my human experimentation to generate a formula for a bovine specimen, or so I believed. Unfortunately, trying to replicate the successes and negate the failures of my previous experiments has been quite difficult. With the deadline mere weeks away, I can not help but question whether I will be able to finish the formula by the assigned date.

"Gah! Why can't I get this damn formula down?!"

Amaya had to fight back the urge to slam her fist down in frustration as she watched the results of her latest chemical formula fall to pieces on the computer screen in front of her. She was so sure she had it this time, too! Her human experiments proved she was on the right track; she just had to apply the results to a bovine specimen now.

The formula was perfect in theory, except for the fact that it required too much energy to get started. The average bovine body would simply break down her formula before the formula without ever incorporating it into its biology. She had hoped to get around this by introducing a glucose solution that the body would break down first, causing a chain reaction of interaction to begin reaction with the subject's body. Despite the seemingly perfect solution, however, the formula continued to remain stagnant even in the energy rich solution.

Blinking back tears of frustration from her soft brown eyes, Amaya steeled her resolve and went back over her notes again. She knew she was on the right track; she just had to overcome this hurdle. She just need to take a deep breath and look again to see where she went wrong. Amaya had been cutting herself off from her friends by this point, in part to focus on her work and in part to keep them safe from her botched experiments. As soon as this was over, she resolved to take a long vacation, and take Rebecca and Sandra along to thank them and apologize. She just had to steel her resolve and not let disappointment blind her to her ultimate goal in the meantime.

BRRING BRRING! BRRING BRRING!

Oh, come on! A phone call, right when she was on the cusp of a breakthrough?! Amaya decided to let the call go to her answering machine and focus on her experiment, and after a few more rings the phone went silent. With a sigh of relief, Amaya returned to her formula.

BRRING BRRING! BRRING BRRING!

Again?! A slight grow of frustration escaped as she glanced over to the portable phone on the wall. She turned back to her formula on the screen, hoping whoever was calling would get the hint and give up.

BRRING BRRING! BRRING BRRING!

"GAH!" Amaya stomped over to the phone, trying and failing to completely keep her frustration at the caller out of the voice as she picked up the receiver. "What?!"

"Whoa, hey, sorry!" Amaya sighed, trying to get a hold of herself when she heard Rebecca's familiar voice. "If it's a bad time, I can call back later..."

"No, no..." Amaya apologized, walking back over to the computer as she apologized to her friend. "I'm sorry; I'm just in the middle of this experiment, and I think I almost have it; almost being the key word. It's driving me nuts trying to figure out where I'm going wrong."

"You mean your milking formula?" Amaya confirmed her friend's question. "That's not good. Didn't you tell me the other day that the deadline for that experiment at the end of the month?"

"Yes it is." Thanks for the reminder, Amaya added silently. It's not like I need any more pressure than what I'm already under. "I've looked over all my notes, all my models a hundred times now. Nothing seems wrong, but I still can't get the proper reaction!"

"I understand. You do sound pretty stressed, Amaya. Maybe you just need to take a break, and look at it again another time." Rebecca suggested.

"I don't HAVE anymore time!" The frustration was back in Amaya's voice as she went back to the flask containing her latest formula. She grabbed it so roughly that it almost spilled out as she went over to a nearby Bunsen burner, setting the flask on the metal ring above it. "Maybe it just needs some heat to accelerate the reaction. Yeah, that's it, heat!"

"Adding heat to milk?" Rebecca couldn't see what Amaya was up to, but it was clear from her voice that she was concerned about what the stressed scientist was up to. "You didn't need any heat when you injected me with the formula; are you sure you need it now?"

"It couldn't hurt!" Actually, it almost did hurt as Amaya tried to hastily drag over a heavy propane tank. Misjudging the weight of it almost caused her to throw her back out when she tried to lift it too quickly. A brief yelp of pain escaped her as she dropped the heavy tank onto the laboratory floor. Rebecca immediately asked if she was alright, and got a terse reply of, "Yes, I'm fine!"

With a little more control this time, Amaya dragged the heavy container over toward the table with the burner. Though not in the calmest mind she'd ever been, she was still careful to inspect the rubber tubing she grabbed for cracks and making sure the seals on both the tank and burner were secure before opening up the valve on the tank. Within seconds she had sparked and lit the burner.

If she'd just taken a moment to stop and really think about what she was doing, Amaya would have realized she was headed for disaster. She prided herself on her ability to focus and handle pressure, but her lack of progress and the impending deadline was making her careless. She had forgotten to take basic lab safety precautions, like wearing protective eyewear or gloves. In addition, almost anyone can recognize the potential danger that can be caused by someone distracted by a cell phone while they're simply driving a car; the potential catastrophe that could be caused by someone distracted by a phone in a laboratory, a laboratory that was filled with volatile chemicals and dangerous equipment, was even worse.

Amaya continued to speak with Rebecca as she adjusted the intensity and height of the burner flame. Maybe if she just got it just right, it would produce the reaction she was looking for. Maybe she could still save this project after all. Or maybe she should have been paying more attention to the flask sitting above her head, which was already starting to bubble over even from the low flame that was being applied to it.

"AH!" Amaya cried out at the sudden feeling of something wet dripping onto her head. She pulled back quickly away from the bubbling flask, wiping the formula away from her face and trying to keep it out of her eyes. Rebecca's worried voice called out to her as the phone clattered to the floor, concerned for what was happening.

"I'm fine!" Amaya called out, trying to reassure herself and her friend at the same time. "The flask spilled a little, but I'm O.K!."

Amaya tried to steady her racing heart, reassuring that she was alright, that everything was fine. She chastised herself for being so careless and for forgetting such basic lab procedure. She couldn't afford to be so careless in the future. She had to take a deep breath, calm herself and think about what she had to do. She already checked herself and determined that she wasn't hurt; that was the first part. Next was getting some protective equipment for herself. Then she had to clean up the mess she made, and make sure it didn't damage any...

BOOM!

...right; she probably should've pulled that flask off the burner first so it didn't blow up in her face like it just did.

"GAH!" The bubbling formula exploding, sending the milky white fluid spraying all over the lab and its occupant. Everything became coated in the formula, and this time Amaya was unable to keep the formula from getting into her eyes and mouth.

Amaya quickly turned off the gas to the burner, her hand slipping a bit on the soaked valve before she was able to full turn it off. One of the disadvantages of having a lab in her own home was that she couldn't afford all the amenities of a professional lab, including a standard safety shower in the case of such chemical accidents. Instead of immediately being able to cleanse herself of the formula, she lost precious seconds as she bolted for her personal shower, hurriedly stripping and leaving a trail of formula soaked clothes behind her.

Amaya quickly scrubbed and rinsed herself as best as she could, occasionally opening her mouth and gargling a little bit of the water before spitting it out to remove any traces of the formula still in there. The formula had been designed to be injected, not ingested, so she was sure any reaction it would have from her swallowing it would be minimal at best. That was a relief; she was already an E cup, and didn't feel she needed any enlargement in that area.

After fifteen minutes of cleaning and drying off, it was time to clean up the mess she made. The accident clearly demonstrated to her that she was in no shape to be performing any kind of experiment, and she donned an old white t-shirt and jeans as she resigned herself to merely cleaning up the mess and calling it a day.

"What a mess..." She said to no one in particular with a heavy sigh. Grabbing a set of cleaning materials that includes rags, gloves, goggles, and a hazardous waste bag, she began the long, slow process of cleaning up.

Amaya started from the center of the disaster area and worked outwards, returning the burner to its proper place and bringing the flask to a cleaning rack near the sink. Next was the lab computer, which thankfully was spared any damage save being messy with formula. After wiping the keyboard as best she could, she quickly saved her work and powered down the terminal.

"Hmm?" Without the hum of the computer's tower filling the room, Amaya could hear a new sound. It sounded kind of familiar, like the tone a phone makes when someone leaves it off the hook...

"Oh no, Rebecca!" Amaya quickly ran back into the adjoining house to get her cell phone, not wanting to handle the formula covered phone. Removing her thick gloves, she quickly dialed Rebecca's home number to assure her friend that she was O.K. The phone rang several times before going over to the answering machine. Figuring Rebecca was probably on her way to check on her, Amaya tried her cell phone number next.

"Amaya?! Oh thank God; are you alright?!" Amaya felt terrible about making her friend worry about her, but she still couldn't help but smile a little upon hearing Rebecca's voice. I'm lucky to have such a good friend, she thought to herself.

"It's alright, Rebecca, I'm fine." Rebecca let out a big sigh of relief as Amaya spoke. "I'm sorry if I made you worry."

"Damn right you should be sorry! I thought you were in some real trouble over there!" Rebecca's tone was harsh, but Amaya could sense Rebecca was just as relieved as she was. "I'm already halfway to you place!"

"I know; I was being stupid and careless, and I'm sorry." Amaya apologized again, slowly scratching an itch along her arm. "I think I'm just gonna clean up and call it a night over you. Moo don't need to come over."

"Huh?" Rebecca sounded as puzzled as Amaya felt. "Did you just say, 'moo?'"

"I think I did. Maybe I have been working too long on this cow project after all!" The stress of this project really is getting to me, Amaya thought as she tried to laugh off her speech slip. "Anymooooo, yoooouu..."

"What?" Amaya clamped her hand over her mouth in shock. Uh-oh; maybe that formula wasn't as harmless as she thought!

"Nothing! Gotta gooooo!" Amaya hurriedly hung up with Rebecca and dashed back toward her lab. She tried to ignore the feeling of heaviness and sluggishness that was slowly creeping into her body as she hurriedly dashed toward her terminal.

"Come on! Mooooove it!" Amaya yelled at her computer. She imagined the growing heaviness and weight in her chest was just a stress reaction as she gathered up some of the formula(which since it still coated a good portion of the lab, didn't take too long) on a viewing slide, but she was pretty certain the sight of her shirt starting to stretch and fill out more around her chest meant much more was happening in her body.

Amaya hurriedly opened her formula analysis program, her fingers starting to feel clumsier than usual. The ring and pinky fingers on both her hands felt like they were stuck together with glue and refused to separate, the rest of the fingers joining together in a similar fashion. The strange formation her hands were taking made typing difficult, and she had barely managed to get the analysis program open before they seemed to become permanently locked in that position.

"Noooooo!" Amaya watched with horror as her fingers began to feel soft and malleable, almost like they were made out of clay. After several failed attempts that saw her pawing helplessly at the slide laying on the table and seeing the gaps disappearing between her fingers as five small finger slowly became two big ones, Amaya had to settle for sandwiching the slide between her wrists and awkwardly placing it on the attached microscope before nudging it into position with her now almost useless hands.

Peering down the scope, Amaya could see the cellular structure of her formula was incredibly active. Cells were dividing and splitting rapidly before her very eyes, a process that would normal take minutes or longer happening in mere seconds. Amaya continued to stare in wide-eyed shock. Her formula that had previously been a stiff as a statute now moved like it was plugged directly into a live wire of electricity.

"The heat!" Amaya gasped as she continued to watch the reaction on screen while she felt it in her body. The heat from the burner must have broken down the glucose solution enough for the formula to start reacting, and the energy added by the heat caused it trigger at an increased rate. Now that the initial reaction had fired off, it seemed like it wouldn't stop until it had fully used up all the available energy. Giving the potency of the glucose solution she'd used, Amaya knew it would be quite a while until that happened.

Amaya pulled away from the scope, yelping as her mouth suddenly bumped against it even though she was sure she was far enough away. Reaching her hardening fingers to her face, Amaya tried hard not to scream when she felt her chin felt like it pushed out further from her face than normal. Running her tongue over her teeth, Amaya no longer felt any of the sharp, pointed teeth there were good for tearing and chewing away at meet any human like her should have. Instead, all she found were the flat, grinding teeth of a plant eater, specifically that of a cow.

Amaya still had the same cure she'd given to Rebecca and Sandra, but administering it to herself would have been impossible at this point with her hoof-like hands. There was no way she could even handle the vial of serum in her current state, much less draw it up with a syringe and inject it into herself. Logically she knew that, but it didn't stop Amaya from trying anyway, knocking the vial of serum onto the floor in her panicked haste.

"Cooooome back here!" Amaya fell to the floor to chase after the serum vial, trying hard not to notice the loud, "CLOMP-CLOMP!" sound her hooves, definitely hooves now, made as they hit the floor. Attempts to grab the vial just made it slip further away from her. The best she could do was put her hoof atop it to keep it from getting any further away.

Amaya tried to stand up, to look for something that would allow her pick up the medication. The confusion was clearly written across her shifting face when she was only able to rear up slightly on her back legs before falling forward again. A second attempt to stand ended the same way as the first, making Amaya's chest sway back and forth as she landed roughly. Her first clue as to why she couldn't stand properly anymore was how strangely loose her shoes felt on her feet. Her shoes fell off her feet as she stepped out of them, her socks following the same pattern a second later. Glancing between her arms, Amaya could see her feet had taken on a shape almost identical to her hands.

A gasp of shock suddenly escaped Amaya, though not at the shock of seeing her changing feet. The feeling of her nipples straining against her tightening shirt was weird and distracting, but in her panicked state she'd be able to ignore it for the most part. What forced her to pay attention was the sudden jolt of electricity she felt below her breasts. Stuck in her current state didn't give her the best view of what has happening, but she knew it wasn't normal.

SHHRRIIP!

"MOO!" Amaya's straining shirt could take no more and split under the strain, splitting and hanging uselessly off her arms and back. Another shiver ran through Amaya as her nipple scrapped against the formula covered floor. Her breasts looked much like Rebecca's after she was administered with the second formula, with large nipples and aerola's the covered the entire front of her chest. What she couldn't see from her position was the second set of breasts that were rapidly blossoming below the first pair. The initial strange feeling she felt below her breasts were the appearance of a second set of nipples. She couldn't see them, but she felt them soon enough as the second set touched the cold, wet floor. It sent a shiver down her spine and almost drowned out the feeling of a third set of breasts sprouting under the second, leaving almost no bare space between her breasts and udder. All of the changes sent shockwaves of surprise throughout her whole body, making her teats jiggle with every movement.

Amaya's transformation had already mimicked Rebecca's transformation, and now she was starting incorporate a part of Sandra's transformation as well. Jeans that had felt loose and snug around her hips were beginning to feel tight, like a strange mass was growing underneath. The feeling of four suddenly sensitive points forming on top of that mass told Amaya that her new udder was developing, and very rapidly at that. Soon her pants and panties were following the same suit as her t-shirt, hanging damaged and torn off her bovine butt and back.

Amaya hung her head and let out a long, almost mournful moo. Her brain was still working like a normal human's, but that was the only part of her head, or pretty much her entire body, that continued to stay that way. Even her ears had begun to droop and sag as much as her emotions. She was turning into a cow, and there was no one here to help her. Sure, the formula would wear off eventually, but with the enhancements she'd made, it could be days before she would start to return to her human self on her own. Forget the time she'd lose on her project; at this rate she wouldn't even be able to feed herself!

KNOCK-KNOCK-KNOCK!

"Moo?!" Amaya suddenly perked up at the sound of someone knocking on her front door.

"Amaya? It's me, Rebecca! Are you here?"

Rebecca! Of course! She must have decided to keep coming over when she heard Amaya's strange reactions on the phone! If she could have smiled with relief knowing that aid was just outside, she would of. She instead had to settle for the fleshy numb that was beginning to form above her rear twitching back and forth ever so slightly, the beginnings of a new tail starting to come out.

"Moo! Moo!" Amaya trotted over to the base of her lab stairs as she heard the front door of her home opening, thankful she never bothered to lock the door while she was home. A snort of frustration escaped Amaya as she tried to work with her altered speech patterns. "Mooove! Mooove!"

"Huh?" Rebecca moved through the living room entrance, slowly working her way toward the strange voice. Unwilling to try the narrow stairs that led up from her lab to her home in her current state, Amaya stomped her feet to try and draw her friend toward her.

"Amaya? Why are all of these clothes strewn all over the place?" Rebecca picked up Amanda's discarded shirt from the accident, sounding fairly disgusted by the formula soaked garment. "Uggh! What is this thing covered in?!"

"Nooo!" Amaya believed the growing frustration at her predicament was the reason for the slowly spreading prickly feeling and heat growing across her face. She couldn't see it was actually the feeling of small, white hairs slowly growing and spreading across her face in a thin coat of fur. "Moooove!"

"Who said that?" Rebecca followed the source of the voice, soon emerging at the top of the stairs that led down to Amaya's laboratory. Rebecca was clearly stunned by what looked like a cow that was wearing a wig and missing a lot of fur staring up at her from the base of the stairs. "What the?!... Did Amaya let a cow loose in the lab?"

Amaya shook her head furiously as her friend slowly came down the stairs toward her. A part of her wanted to glomp down on her friend's hand and drag her over to the vial of serum lying on the floor, but she had already made too many mistakes making rushed, panicked decisions. Rebecca might run as seeing what looked like a panicking animal coming at her, so Amaya would have to be patient and just have to nudge Rebecca in the right direction so she could fix her.

Rebecca, for her part, was very confused and shocked. She came her expecting to find her friend in serious trouble, and no one was to be found except for this strange looking cow. She knew Amaya had been experimenting with a milking serum on humans, but it never crossed her mind to guess that this cow in front of her was her best friend. She simply figured Amaya must have found a cow for experimentation, although she was still at a loss to explain the hair.

"Hey there..." Rebecca slowly stepped off the bottom step of the lab and approached Amaya. While she was completely unaware that the cow in front of her was her friend, the strange sight of what she believed to be a cow in a wig sitting in her friend's laboratory alone was enough to make her cautious. "What are you doing down here?"

"Moo! Moo!" Amaya nuzzled against her friend's hand as Rebecca gently stroked her head, looking around at the mess of the lab. Amaya tried to get her mouth to form more human words, but her mouth simply didn't want to make any of the right sounds.

"Well, you're friendly at least; that's good." Rebecca stroked Amaya's head a little more as she examined the mess around the lab. "Damn; Amaya sure did have some kind of disaster in here!"

Rebecca stepped around the cow as she tried to figure out what happened. A part of her really didn't want to be here; after her initial exposures to Amaya's formula, she wanted nothing more to do with it. Still, her friend was missing and something had clearly gone very wrong; she couldn't just leave without checking on her friend's welfare.

"Gah; it smells like spoiled milk in here!" Rebecca moved carefully, trying not to slip on the slick floor as she tried to figure out what happened. She knew her friend would never leave her lab in such a state unless something serious had happened, but beyond that she couldn't discern where Amaya could have gone to. Rebecca glanced back toward the cowed Amaya for help. "Don't suppose you could tell me what happened to Amaya?"

"Meeeooo! Meeeooo Amooooya!" Rebecca tilted her head at the strange response, but didn't seem to understand a word of it as she continued to search through the lab. Rebecca's attention turned toward the still active computer, trying her best to puzzle over what all the results on the screen were attempting to say as Amaya clomped over to the serum vial to try and secure it.

Neither one of them were very successful at their self appointed tasks, Amaya being the first to give up trying to pick up the vial again. She sighed mentally as she failed to find anything that could point Rebecca in the right direction. If she could just get her muzzle on a pen and paper, she could write a message and communicate better with her friend. Unfortunately, Amaya would first need to somehow communicate with Rebecca that she needed something to communicate, trapping her in a logical loop.

Feeling hopelessly stuck, Amaya glanced down at the mess of formula stuck to her hooves. Looking around, she could see the trail of hoof and foot prints left by the two of them as they walked through the lab. Each step left a distinct impression, the semi-viscous formula leaving a clear trail.

Of course!, Amaya thought. If she could have hit herself on the head for her stupidity, she would have. She could write a message to Rebecca after all!"

Rebecca noticed the strange movements the cow was making, but didn't pay close attention to what the big animal was doing. She was concerned for her friend, and as long as the creature didn't see her as a threat, she was content to let it slosh around in the mess to its heart's content. She found Amaya's notes and journal entries on the experiment, but nothing that would explain where her friend had disappeared to right now.

"Maybe I should just check upstairs again, or call the police and have them investigate." Rebecca looked worried as she turned back toward the cow. "You gonna be O.K down her... what the?..."

Rebecca looked confused as the cow stepped away from the area of the floor where it had been messing around. It looked like the cow had tried to draw something in the muck, and was now dragging one of its hooves along the ground to form a big arrow shape before standing in front of the arrow.

"Are these letters?" The strange medium the cow used and the nature of writing with hooves made it a little hard to tell, but if she looked at it the right way, it seemed like the cow had written something. Rebecca read out each letter slowly. "A...M...A...Y...A... that's..."

Realizing that was her friend's name in the muck, and that the arrow the cow drew pointed from that name toward her, it didn't take much for Rebecca to realize what had happened. That cow didn't just kind of look like her friend; it WAS her friend!

"Oh my God! Amaya, what happened?!" Amaya's now fully formed tail swished back and forth as her friend got the message. "Did your formula do this to you?!"

"Moo! Moo!" Her words were failing her, but Amaya was still able to nod her agreement. She gently taped the serum vial with her hoof, pushing it toward her friend.

"What's this?" Rebecca knelt down slowly and picked up the serum vial, which was now coated in formula itself. The brownish vial looked familiar to her, its purpose coming back to her a few second later. "This is the cure you gave me before, right? Yooou need it now?"

Amaya nodded vigorously, hoping Rebecca would be quick. She was worried the formula was beginning to have some effect on her brain after all; she could have swore she had just here Rebecca moo a little herself.

"O.K; I'll give it toooo yooou!" Amaya's ears drooped heavily as she realized she didn't hear incorrectly; Rebecca was starting to speak like Amaya when she began changing.

"Moooo noooo!" Rebecca looked down in horror at her chest. She was already beginning to feel the same transformation she'd experienced with the first version of the formula. The strangely familiar feeing of her chest getting rapidly heavier and her nipples broadening across her chest were occurring at an accelerated pace, even faster than Amaya's transformation.

Amaya watched with surprise and shock as Rebecca's fingers started fusing together, becoming hoof-like in mere seconds. Amaya could only theorize why this was happening to someone who had only minor contact with the formula, but she assumed some part of her first human version of the formula must have still been floating around in Rebecca's system. The formula would only need the smallest opening to get into Rebecca's bloodstream, and her body was already familiar with a similar version of the formula. Somehow the new formula was being incorporated into her body, transforming her at an incredibly rapid rate.

Rebecca didn't understand the science behind what was happening to her, but she knew she had to act fast. Amaya clomped as fast as she could toward the drawer containing the syringes needed to give the injection, biting down on the handle and puling it open with her teeth. She mooed loudly, trying to get Rebecca's attention toward the drawer before it was too late.

"Moo?!" Coming from Rebecca this time, she glanced toward the open drawer and saw what was inside. She only made it two steps toward the drawer before a sudden spasm rocked through her body, sending her sprawling to the floor. The hard impact drowned out the sound of the vial flying across the floor and the sound of her shirt tearing as her udder-like breasts tore through the strained fabric.

"Noooo!" Rebecca grunted furiously as her legs shifted, rapidly losing strength and gaining a set of hooves. She tried to stand back up, but the growing weight on her chest and strange feet made such a feat impossible. "Need help!..."

Amaya was busy searching for the serum vial, and didn't notice Rebecca stumbling over to the phone she'd dropped earlier. As Amaya carefully knocked the vial out from under the cabinet it rolled under, Rebecca hit the, "END" button on the phone. When she hit, "TALK", she nearly crushed the phone under her hoof. Dialing a full phone number would be almost impossible, but she knew Amaya's phone could dial someone by giving the person's name if she could just say it properly.

"C-Call A-moo..." Rebecca tried to control her speech as best as she could as she felt her face becoming rubbery and more cow-like, knowing only one other person who could help them at this rate. "C-oo-all A-moo...Adela!"

If Amaya could have ran over and hit Rebecca, she would have. Adela?! Really?! She was Amaya's friend as well as Rebecca's, but she was also Adela's scientific rival. She was the absolute last person Amaya wanted to see stuck as a cow as a result of her own careless experimentation.

Rebecca could feel the death glare she was getting from her bovine buddy as the phone rung, returning the glare right back at her. She knew Amaya wouldn't be happy about this, but beggars can't be choosers. It was either Adela or nothing.

"Hello? Amaya?" Adela's voice picked up on the other end of the line. "I saw your name on the caller I.D; what's going on?"

"Nooot Amooya! Rebecca!" Rebecca had to move in front of Amaya to keep her from trying to hang up the call as she tried to speak to Adela. "At Amoooya's lab!"

"Rebecca?" Adela was clearly confused by the strange speaking patterns, and the sound of Amaya's protesting moos. "You sound strange; is everything O.K over there?"

"Moo! Mooot O.K!" Amaya tried to maneuver around the bovine blockade her friend was putting up. With cows not exactly known for their mobility and the slick lab floor, she spent more time trying to keep from landing flat on her udders than she did interrupting Rebecca's call. "Need yoooouuu!"

"You need me?" Adela was clearly a mixed of puzzled and concerned. "A-Alright; I'll be there in a few minutes. Should I bring anything?"

"Moo! MOO!" Adela wasn't going to get any further explanation as her ability to speak was quickly lost. She dropped her head, partly in disappointment but also in slight pain at the slowly emerging set of horns coming from either side of her head. It felt like she had a splitting headache, only with something actually splitting through her scalp and coming into view. She was soon joined by Amaya a few seconds later as her own horns started to emerge, both women with completely cow-like heads save for their human hair.

Adela only lived a few minutes away, but it felt like it was taking ages to the cows in the lab. Most of that had to do with the fact that the whole reason for Amaya starting this project, to increase lactation in cows, suddenly started to kick in. Their already heavy breasts and udders began to feel even fuller as a heavy, thick liquid slowly started to fill them. A small stream of milk started to leak from the combined ten nipples each girl sported, one on each of their six teat-like breasts and the four on their udders.

Amaya shuddered as she felt the pressure building up within her, starting to wish she hadn't been so successful with her formula after all. Despite all the space available within their massive breasts and udders, in the span of less than two minutes every one of them felt like they were on the verge of bursting. Puddles began to form under the cows as milk slowly began to dribble out, but the tiny drips offered little comfort or release. Both girls needed to be milked, and milked now!

Within what felt like the longest ten minutes of Rebecca and Amaya's lives, they heard the sound of Adela's voice calling out to them. Both of them mooed frantically, tails swishing happily when they heard heavy footsteps approaching the top of the stairs.

The two cows were almost as shocked to see their intended rescuer as she was them. Adela had apparently been concerned about a potential hazardous chemical spill, and had donned a bright, banana-yellow self contained hazmat suit before entering the house. The cows could barely make out her bright green eyes or chestnut brown hair behind the heavy face shield, but it was definitely Adela's voice that spoke to them as she slowly made her way down the stairs toward them.

"Cows? Cows in here?" Adela's thick rubber gloves reached out toward Amaya, getting an angry moo from her when she tugged the hair on her head. "Cows with human hair, no less! Strangely familiar hair, too..."

Seeing the terminal still active, Amaya's scientific rival eased her way over to the computer. Being on the same level intelligence wise as Amaya, it didn't take long for Adela to put together what had happened after reviewing the formula and reading through Amaya's notes.

"Looks like you two had a bit of an accident here." She knelt down and picked up the serum vial on the floor, seeing the intensity both cows stared at the brown vial with. "And I'm guessing you need this to get back to normal, huh?"

Both cows nodded furiously, and as much as Amaya hated to admit it, she was glad Adela was here. She could finally get back to normal! As she gently nudged the drawer containing the syringes, she begrudgingly admitted she'd have to give Amaya some sort of credit for helping her. She'd probably want a little more than just her name on the final project; she'd probably demand a piece of the research money and be noted as an equal partner instead of just an aid. It hurt Amaya's pride, but she wasn't exactly in a position to negotiate... hey; why was Adela closing the drawer with the syringes? And why was she putting the serum vial away before giving it to her or Rebecca?!

"You've done quite a lot of good research here, Amaya..." Even with her face partially obscured by the mask, Amaya could swear she saw a wicked smile crossing Adela's face. "It would be such a shame to end the experiment so soon, don't you think?..."

No, Amaya thought, it would be wonderful to end the experiment now. As she watched Adela starting adding her own notes to Amaya's on the terminal, though, it started to dawn on her that it wasn't going to matter much what she or Rebecca thought. They were completely at Adela's mercy, and judging by how she was researching home delivery of milking machines and other cattle equipment, they weren't going to go back to being human anytime soon...

From the journal of Adela, continuing for Amaya

Day 180- Today's demonstration at Mama's Milk went well. They have approved and accepted my formula, and payment will be rendered shortly. They are, of course, unaware that the formula they received is only a fraction as potent as the one I have for my personal use. I will be reinvesting their payment into expanding my personal operation, and soon Mama's Milk will have some serious competition in the dairy industry.

Adela smiled as she finished her latest journal entry, looking through the laser field fence at the two cows contained within the makeshift pen Adela had set up in Amaya's lab, Both Amaya and Rebecca had received their latest doses of the formula to keep them in their cow forms, giving Adela at least another week before she had to worry about administering another dose.

"Now now, no need for the long faces." Adela smirked as the two cows looked at her with a rotating pattern of anger and relief; anger for keeping them in their cow forms, and relief as the milk machines they were hooked up to drained the ever present liquid from their udders. "You just have to hold on until I receive payment for my work and I can get some replacement cows for you two. In the meantime, you girls are just going to have to hold tight."

BRING BRING! BRING BRING!

"Hmm?" Adela's attention turned toward the nearby phone, making sure to step far enough away that the mooing cows wouldn't be heard as she answered. "Hello?"

"Adela? It's Sandra." The young lady sounded concerned as she spoke. "What are you doing at Amaya's house?"

"Me? Oh; I'm... looking for her." Adela smirked as she glanced back toward the enclosure she'd formed in the lab. "She hasn't been seen for a while, so I thought I'd stop by here and see if she was just hiding out at home. There's no sign of any other human life, though."

"Really? I was getting worried because I hadn't seen here a while; I tried Rebecca, but she seems to have gone missing, too. Do you think we should call the police?"

"Oh, I don't know about that. The two of them could just be taking a little vacation, after all. When I last spoke to Amaya, she was really looking forward to taking a break." A sinister thought slowly entered Adela's mind. "Hey; were you taking part in any experiments for Amaya lately?"

"Yeah; I was helping her with some sort of thing for cows. Why do you ask?"

"Oh, no reason. Listen, why don't you come over here? Maybe the two of us could figure something out about what happened to Amaya."

"Huh? Sure, I guess. I'll be over in a bit." Adela couldn't help but let out a little chuckle as she hung up the phone. Looks like she'd be getting another cow sooner than she thought...
