Kick In The Dairy Air
Your wife accidentally gets some alchemical bovine hormones on her and it makes her breasts larger- sweet right? Well she thinks so too, because she stupidly drinks a second dose. It is supposed to be for cows. Well now your wife Lala is a half cow, and without hooves you now have to do basically everything for her, including bathing her. At least you get all the free milk you can drink, right? What could go wrong... er, what MORE could go wrong I mean.
(Male POV, F tf Cow-half, tf cow, M tf bull)
You are a rancher of the city-state of Andeva. Your ranch is a modest one, but thanks to alchemical advances you do not need to expand your land nor the herd of cattle. Using alchemical potions you can make sure your cows remain big and milky without actually needing to be pregnant- well, aside from keeping the herd size the same.
You were so startled when your wife burst in through the door suddenly that half the coffee in your mug jumped out from your movement, and luckily landed right back in the mug again.
Lala is a smart woman but, uh, more than a little absent-minded, so she ends up making a lot of bad decisions in spite of knowing better. If you wanted to see her real intellect you'd need to get her to sit still first- and good luck doing that. She came into the house again looking disheveled and her top is moist from something spilling on her. More alarmingly- her top is a lot more full than normal. She likes oversized tops- which are hard to find because she is a rather big woman. You are not at all short yourself, and she is the exact same height as you. The sleeves of her hoodie are still too long for her arms and hide all but the tips of her fingers, but her enlarged breasts now fill the body of the sweater and pull it away from her! You can see a stretch line across from the bump of her nipples in the shirt from one side to the other. Well... that isn't normal. She is out of breath and her expression hovers between bewilderment and giddy pleasure.
"I... I almost gave Juniper a dose of the serum."
You nod, motioning with your free hand for her to continue. "Right...? She is looking to have a young'un though, so she is supposed to be off the stuff. Her calf will be needing her milk soon enough."
"Y-yea! Right! I remembered before I gave it to her, but when I went to put it back on the shelf I misjudged the distance and I... I thought I broke the vial! The vial was fine but- I mean it did hit the shelf but it didn't break- and I was startled so I fumbled it entirely and dumped it on my top!"
Oh, well, that explains her breasts then. She dumped alchemical bovine hormones onto herself. It is meant to enlarge the mammaries to their full potential and induce lactation. She is lucky this is all it did to her.
You motion to the hall on the other side of the kitchen. "W-well go get yourself washed off! And toss the top in the laundry. That serum was not meant for humans!"
She blushed. "Right..."
You watch her as she skitters off- a bit stunned by her size.
Normally Lala is a tall woman, with aquamarine eyes and light orange-brown hair. Her hair is to her lower back, but gets bouncier the further down from her head it goes, so it ends up curling back up to her upper back unless it's wet. Her skin is a light peach and the top of her breasts, her forearms, the back of her neck, her cheeks, and the bridge of her nose are speckled with constellations of freckles. Her breasts are supposed to be C cups- the perfect size to fill a hand, with solid edged areola of a powder-brown tone. When she came back into the kitchen she was still drying her hair with a towel- she put her shorts back on but as you told her; she put her top in the laundry, and didn't bother to grab a new one, walking around topless now. Her areola now have a bit of a faded edge to them from being rapidly stretched across the expanding bust, and their coloration has turned much more aggressive. They are now a dark red-brown, and since she went from a warm shower to walking around topless, the air has made her now large nipples stand in full attention and the surface of her areola become goose-bumpy. Her breasts looked to be in the range of a G cup at least, but, springier than any other G cup tit you've ever seen. They aren't solid or round like implants, but they also sit too high for a normal G cup, the skin's elasticity was enhanced by the serum as well. Rather than flop or slosh around like huge breasts do- they wobble and bounce.
Completely unprovoked, Lala starts to turn back and forth for you, giving you the bedroom eyes. She walks up to you all sultry-like and stands with her chest out, offering you to sample her melons.
"Well?"
You chuckle, putting your mug down on the counter. "Well, I want to be more concerned than you seem to be. Should I head into the city proper and find an alchemist?"
She bent her torso the other way as if to protect her new assets from the concept of having them 'cured'. "Nuuuu, they are so expensive! Besides- are you forgetting? We need to re-apply the serum every year. It wears off, on its own."
"You're going to stay like THAT for an entire year?"
She cocked her brow. "Any complaints?"
You place your hands on the soft sides and draw them forward, then slide your hands under them to heft their weight in appraisal. You slide your hands to the front, catching her erect, enlarged nipples between your fingers before shoving her breasts back toward her. You can feel the soft, rubbery flesh billow up between your fingers.
"Can't think of any myself, just feel a bit unsettled is all."
"Mmm." Lala glances you up and down, licking her lips. "Well instead of going with your gut on this one- why not get the opinion of something lower?" She placed her index on the bulge at the front of your pants, pulled down and giggled as she let go and it sprang back into place.
It is funny how night-and-day Lala can be. When on the job or out and about she is quite serious and her reactions quite reserved. When she is alone with you however- she is a complete goof, and often a perverted one at that. Of course she is giddy about getting a huge pair of tits. After spending most of the morning romping in bed with her, you ended up doing her turn of the chores and tending the cows where she abruptly left off. By dinner she was already joking around about deliberately taking a dose of the hormone serum! Of course you laughed it off, but you also made sure to emphasize how dumb that would actually be, just in case she was actually humoring the idea in her head. Yea, it wears off- not quickly. Also, a dose is meant for a cow; a creature that is both different in biology to a human, and also at least twice the size of a human. Assuming she isn't mutated horribly- the dose lasts almost a year for a cow; how long would that last in a creature a third of the size? Three years? Can you imagine?
Well... you wouldn't have to imagine for very long.
The day after the next, you heard a clattering in the barn in the early morning. You covered what she did not on her last turn, then did your own turn, so today was once again Lala's tern in the barn to milk the cows. They produce enough to be milked twice a day, but the morning milking is done by hand instead of machine so they get a balance. There is a lot of heavy equipment in there for maintaining the land and such- so you step out onto the deck in concern and call to her just to make sure she didn't somehow knock something over large enough to pin her.
"Lala? You alright?"
"M-moo!"
Your brows immediately lower. "Right. What was all that ruckus?"
"MOO!"
You just shake your head and are about to go back inside, but your gut tells you something is amiss. She is obviously trying to be cute with the moos... but what if she is really planning to do something with the serum? Just to make sure she isn't doing no mischief you dash over to the barn to look in on her. Your heart almost jumps into the back of your throat when you see her on the floor of the barn. It looks like she stumbled over several things and made a right mess of the equipment at the back of the barn- around the shelf where the serum is kept. She transformed! That fool woman actually dosed herself with bovine hormone serum! The first dose only made her breasts larger because it just fell on her chest- she did not ingest it! This dose she actually drank, so it caused her body to radically mutate!
Lala's breasts are still a bit larger; you are not sure what bra size would fit her now, but luckily they are not too much bigger than their already enlarged state. The serum is meant to bring out their greatest potential size- so this is Lala's largest potential, her genes won't allow them to get any bigger. They do however now have company. Immediately below her original breasts is an all new pair of breasts fighting for space! The second pair of breasts is not quite the same size as the top ones, they are roughly 70%. Her sweater is once again overfilled- the top breasts compacted so tightly in the fabric you might actually have to cut it off at this point. Obviously since the top pair stole all the fabric- her lower breasts were just out and about with nowhere to go. The front of her jorts have bust open as well, letting soft candy pink mammary flesh to billow out the opening! She has a cow udder, though rather timidly sized- each segment of the udders is still a bit smaller than her lower breasts. It was also extremely round and tight, the skin pulled completely smooth- but that is because it's being strangled by her shorts. She does not have fur, but some cow splotches have appeared on her skin, almost the same color as her hair- though slightly more pale.
Lala's nose is now very wide and shallow and candy pink on the squared end, trailing down to her lips, making it look like she has the face of a cow, without actually having a muzzle. Her ears are huge and leaf shaped- they can pivot around but are so large compared to the size of her head that they normally just flop down at the sides. She has horns, but they are so small and underdeveloped that they never actually managed to break the skin- they are just rounded cones in front of her temples. She has a cow's tail but it is unusually long, and the tassel on the end is also abnormally long- trying to imitate the hair on her head. The most alarming- for both of you- is that all four of her limbs now ended in cloven hooves! Her arms and legs remained the same down to the wrist and ankle, and from there became the hooves of a cow... which means she has no hands anymore to take care of herself.
You put one hand on your hip and the other through your hair, letting out a distressed sigh. "Well, I hope you are happy. You wanted their endowments so bad you got a lot else too."
"Moo."
"Yea- ha ha, real cute. Don't you have anything to say for yourself?"
"M-mum..muuoo? Moo."
"Okay, I get it, can you say something other than moo?"
She shook her head vigorously.
"Y-you can't... say anything other than moo?"
She nodded.
"Oh goodie."
Her throat isn't transformed, and her voice still sounds exactly the same as it always has, so her vocal chords are unaltered, there is no reason for her to only be able to moo- whatever is causing it is a mental wall, not a physical one. Since her voice is unaltered it just sounds like a woman trying to be cute and mock a cow, rather than anything remotely close to an actual cow lowing.
You are a bit startled when she stands up- you did not realize she was taller too. Her body did not change size, but her soles stretching and fusing into cannon bones gave her at least a foot of extra height, and since she was already as tall as you are- you are now on-level with her top cleavage. You see how shakily she is getting up and offer a shoulder. She can walk on two legs still, but has never stood on hooves before so she doesn't know how to balance yet. The massive increase of weight on her front side likely does not help any. Once you get her back into the house you help her slip off her shorts, so her udder isn't being pinched in the crook of the open zipper. Once it's loose, you are able to see how soft it really is. It completely eclipses her pussy from the front and sits comfortably in her lap when sitting or standing. The teats are still larger than her enlarged nipples but not by a lot. About the size of a pinky finger. There are two milk veins running into the udder, and the soft veins drag the candy pink coloration of the udder up her torso slightly across their surface. You push on them and they squish in easily- they are large and fat but not particularly solid. The milk veins run a supply of blood directly from the heart to the udder, bypassing everything between, but she likely still has a normal human heart, and a rather small udder, so the milk veins aren't really necessary in the first place.
You try to get her top off but her breasts move with it- they are super-compressed in the fabric. You try to take advantage of how soft they are and push on the tops through her collar to see if you can pop them out individually, but the tightness of their confines has made them taught. You leave her for a moment on the couch and come back with scissors. She makes a pouty face and gives a frustrated 'moo', not wanting you to destroy one of her favorite tops, but she can't stay like this either! You only actually half-close the scissors on the bottom of the hoodie; as soon as the fabric has the tiniest cut in it, it turns into a massive tear that erupts up to the collar and bursts the front of the sweater open immediately! Her breasts being released from the pressurized top fly forward and slap your chest before flopping down, hitting one another, bouncing to the sides, and then settling back down in the middle with a dull clap. The bottom pair of breasts help steady the top, so they don't take a half hour to stop jiggling. Whenever you leave her alone for more than a few seconds she starts to moo to herself with a confused and frustrated look on her face. She doesn't seem to understand why she is making that sound, either. She thinks of a word, how to say the word, and then just moos.
She has all four limbs up on the couch, parked in the middle of it like some sort of gargoyle. You sit beside her, putting your arm around her shoulders and started to ask her a ton of questions- trying to narrow down what her feelings on all this are, since she cannot tell you directly. She cannot talk, and she doesn't have hands so she can neither tell you verbally nor write words to communicate- so all her answers have to be either yes or no so she can answer with her head shake only. Beyond logic- she still refuses to see an alchemist. She actually intends to wait out the serum's effect. She knows more about alchemy than you do by a long shot, so maybe she knows something you don't? In any case, you can't very well drag her to go see someone- if she doesn't want to go, she doesn't go. As disgruntled as she is at some of her changes... she seems to very much enjoy her new assets- all of them. She grins at you with her adorable cow-face and leans into you, to force you to lay back. You can feel the heat from all her soft mammaries press on you and she kisses you deeply. Her tongue shoves yours up to fit under it, and then coils around it at the base! Woah. Her tongue increased in size, too.
She scoots herself forward over you pushing on the couch with her rear hooves and sits upright, pushing on your chest with her fore hooves. It is a good thing you are still dressed- she just grew those hooves so they haven't been dulled against the ground, their edges are probably pretty sharp. She does a few playful bounces, squishing her bubble butt against the bulge in your pants before getting up onto all fours long enough to hook one of her rear hooves on the top of your pants and kick them down! When she is on all fours like this, all of her nipples and teats rest against you- her mammaries are large enough that they completely fill the gap between your two bodies so the nipples are bent against you. When she plops back down onto her rump and your now nude groin- you notice damp spots on your shirt from where her nipples had been. She must be lactating now! She grinds her pussy on your shaft; your penis wedged between her lips, but the wrong way. When she sits like this her udder is fully rested against your lower stomach, it's very warm, but it isn't leaving any lingering wetness, so she isn't lactating from there... yet. You reach up and cup the front sides of her massive top breasts, letting them wobble with her every motion against the palms of your hands. The way they wobble back and forth- you can feel the liquid inside. It influences how the entire tit shifts, like a balloon full of water. You also notice her areola are projecting out of the surface of the breast and her nipples have gotten thicker- she likely developed milk reservoirs in her breasts like a cow has in their udders. Her nipples will remain swollen huge with liquid pressure until she is milked.
Lala finally slides her hips far enough forward that she can hook the head of your cock in her vaginal opening- and this also causes her udder to roll forward enough that the lower two teats are jabbing into you for a moment. She pauses a moment teasing you before sitting back down heavily and swallowing your dick into her pussy in one quick motion. All of her tits jostle around from the heavy motion, and you can see her nipples are large enough in this form that they flop off-rhythm from the breasts themselves because of the weight inside. She moans, but even her moans sound a bit like moos. Actually, since they are lower pitched they sound more like cow moos than her actual lowing does. She archs her back and starts riding you earnestly. Her udder just rocks slightly- it droops enough that even when she pulls up the udder does not actually lift up off you with her. Her top breasts spring up and down with her bouncing almost like a cartoon while the lower ones remain relatively still. The top breasts have both their own elasticity and the fact that they are bouncing off the tops of the lower breasts, making this motion particularly springy. The bottom breasts do not lift off her, but they becoming shiny and extra smooth with taughtness as the top ones flop down on them and squish them when she drops down. Sitting up like this- she is giving you a perfect view of her breasts. She towers over you in this position so you have a full view straight up of all four breasts, since the bottom are smaller than the top; you can still see the top breasts past them, and the bottoms are the roundest part of a boob. You can feel her tail lashing around randomly, and reach over with your right hand to touch it- as soon as it feels your touch the tail quickly coils loosely around your forearm! You hold the base of the tassel in your palm- it has to be at least two or three feet worth of hair hanging off it- well beyond any normal cow. With your other hand you pat the top of her udder and grab onto the teat, pulling it out from her to see just how elastic it is. Her pussy grabs onto your cock with a rhythm identical to a throat swallowing- trying to devour your meat. It is a good thing her vulva did not change- you doubt you would fill a cow. She rides you, moaning and mooing as you start to feel a sporadic patter of milk drops- all the movement was shaking some of it out, and the sexual arousal was turning up her production. You notice all four of her breasts are blushing- they are at capacity, they cannot hold any more.
"Ah... hah... ha-aahmm muh... m-mo-mouu! M-MOO!" She blushed at the sounds she was unintentionally making, trying to once again talk, and failing.
Lala was likely telling you she was close to climax- because it was only a moment later that her pussy put the death grip on your cock and she shrieked in pleasure. You could feel her hot pussy juice pool and run off either side of your hips and several thin streams of milk erupted from all four of her nipples for a moment! The pleasure caused muscle contractions- which caused her to auto-lactate because she was so full! Her vaginal spasms sucking your cock for all its worth sent you over the edge quickly and you came into her. She flopped down on top of you, with your wet shirt between. When she flopped over your softening cock popped out, and her udder rolled over and covered your genitals with a different but equally soft flesh. You put your arms around the small of her back and hug her tightly- she wheezes from your grip and you grin knowingly as you squash all eight teats into yourself. You two would remain like this for some time- too comfortable to move. Especially knowing how much you had to clean up now, because she absolutely just drenched the couch in various fluids.
When you two get up, she heads to the shower and you wander toward the kitchen to get some water, but hear a timid 'moo' from the hall. Lala is just standing there, and after a moment, lifts her fore hooves up to show you, blushing a bit. Oh right... she can't hold the soap if she doesn't have hands. She cannot bathe on her own- she needs you. You sigh to yourself as it starts to dawn on you how this is looking like it is going to play out. She gets the far better end of this deal- she waits out the serum, while you are essentially her servant. She can't do anything on her own, so now you have to do everything for her... great. Well you had to have a shower too anyway so this part at least isn't any sweat off your back.
You tilt the shower head unusually high up, so she can stand at the front of the shower and not get the water beams in her face the whole time, since you will be occupying the back. She puts her arms up and turns slowly as you lather her body up in the steamy shower. You notice when soaping up her hooves that the two segments do have some movement- she can wiggle them a bit, so she probably can hold small objects by wedging them between the two segments. You give her a playful slap on the butt when she turns her back to you and she giggles. She has small venus dimples on the small of her back- a mark of an fit female form. Ranch work can be hard work, after all. Her hips are small for a woman of her size, but her rump is a perfect bubble butt still. Not very big, but quite round all the same. Lala lets out a cut-off moan when you grip the base of her tail to get the soap down its very long length, so you make sure to move a bit slower and be gentle with it. A cow tail is quite thin, and isn't used for much else than swatting away flies... but Lala's isn't normal. Something about her still being over half human has given her tail more than it should have- it is both abnormally long, has freakishly long hair on the tassel, and it has much greater muscle control than it should. She can control its movement the entire length of it- and coil it around things to grip loosely. It does not have much muscle, so she can't really pick anything up with it; it is too weak. There is not a lot of room in the shower so her butt hovers around your lower gut- she is taller than you now after all, it used to be perfectly level with your crotch and she could pin you to a wall with a backward thrust into your dick.
When you clean Lala's front, it is actually hard to rub her udder. Between the very smooth skin, its amorphous nature, and the soap in your hands the flesh immediately slips out of your grip! At its base you notice the neon pink flesh trailing onto her pubic mound. She is udder right up to her pussy- negating her pubic hair. It also means you cannot lift or pull her udder forward without also tugging on her pussy below, because the two tender bits touch one another. You also note that it looks fuller than before- it is likely producing milk like her breasts, but started later and has a greater overall capacity. You squish the fat milk veins leading off the top of her udder to trace her stomach up to cup the underside of her many breasts. If you push up on the lower breasts, the top divide themselves slightly to make room. Being larger and fatter than the lower breasts, their position can be shifted easier than the lower two. Her stomach is firm, but she is not athletic enough to have visible abs. Tight tummy muscles also means tight vaginal muscles. Her breasts are multi-colored thanks to her splotches. One spot covers the entirety of her lower right breast, making it a diffused brown while the other is still her normal peach tone. You smile as you think to yourself; 'one chocolate breast, and one vanilla'. Her larger upper breasts are nearly the same, but in reverse. The top right breast is bare while a large spot covers the front of the left- it does not quite cover the entire breast, but it's close. She also has a spot covering a fourth of her face- right over her left eye. She is careful to hold her ears down and toward her head the entire time to make sure water doesn't get in- they are a very large surface to get water in now after all. Once you lather her up she immediately moves forward and pins you to the wall of the shower!
"Ah! Come on, we will slip if you are not careful!" She actually slipped several times already, but since you already had your hands on her, you just caught her. Her hooves have zero traction on the bottom of the tub.
You lower your brows and just enjoy the ride after a few moments and realizing what she is doing. She is lathering YOU up. She is transferring the soap onto your body by rubbing herself all over you! She uses the tassel on her tail like a lathering brush to soap up your floppy cock and balls, and rub your taint back and forth while her assortment of mammaries squish and slip all over your torso.
After the shower you are both able to dry yourselves off, but you follow her back to the bedroom to help her comb her hair- her tails needs to be combed now too. Combing it out helps it dry more and every stroke of the comb seems to cause the hair to curl more, creating waves and then wild lashing strands. Her hair became two colors when she transformed, adding snow white streaks to the orange-brown. You suppose her body would have turned the same color, except she doesn't have any fur, so her skin outside the splotches remain peach instead of white. When you look at the very top of Lala's head where it all stems from, the orange hair grows out in an x shape while the white in a + shape. On her tassel the white streaks flank the brown on either side. She has gotten you to comb her hair out sometimes even when she still had hands- it is very relaxing to her to have her very long hair brushed. While you sit on the edge of the bed combing her hair out, you hear an unhappy sigh and look to her face, seeing that Lala is looking at her hooves. She has both her legs folded under her to one side, and is touching her hind hooves with her fore hooves. On closer examination you notice there are a lot of hairline scratches on the surface of her hind hooves that the fore hooves do not have. Is she upset that they got scuffed up? Or just the fact that she has them in the first place?
She cried out in distress suddenly. "Ah! Ah, my m-mun... hum-moo, oouuuuuUU. ARGH." She stood up and stomped her hoof in frustration at still being unable to talk to tell you what is wrong.
Her body told you what was wrong quickly enough when there was a very loud, hollow pop, and then another! A bone shoved up into her skin from her side, looking like she somehow broke something painfully while not even doing anything, but no... you recognized the shape easily enough. That is her hip bone- bovine hip bones look very sharp and push up visible through the skin easily, because their pelvis is shaped like a V- the part you see is either side of the top. This is because there needs to be a large opening so the bone does not interrupt all the soft squishy bits flowing into the udders. They are however complete garbage for trying to walk on two legs. When her hips popped, Lala's torso was jarred abruptly forward, wobbled, and then at the second pop when the bones became visible on the surface; she was forced to bow forward! Her hips rapidly started to grow with a stiff, groaning sound from her bones like the bark of a tree that is being bent in the wind! She lifted her arms up looking like she is trying to do a puppy dog pose, but you then notice her shoulders growing! Her shoulder blades and where her arms hinge are altering to be much further forward- she cannot put her arms into a normal resting position like that! Her thighs start to grow longer vertically and take on a vaguely triangular shape as she is forced to bow further and further forward, teetering to try and keep her balance! Finally Lala is forced onto all fours and her hips and shoulders both give a dull pop to indicate that they have set fully into that position- robbing her of her ability to stand! Oh no, she has become even more cow!
Her udders and teats flop around under her from all the movement- you are given a great view of that from behind now that she is forced onto all fours. Her breasts wobble and jiggle more erratically, because they keep colliding with one another and changing course.
She looks at you with distress and concern in her beautiful aqua eyes. "Moo! Muh... mu- OUUU. Muh-huh." She lifted a hoof to point to her own torso the best she could, but her shoulders did not allow her to rotate her arms hardly at all. "Mhuh, mooom oouu, ah- ouu...rrRRR." She stomped her hoof again, tucking her ears back.
You did your best to try and understand. "You?"
Her ears twitched back into neutral and she nodded.
"You transformed more. I can see that."
She shook her head aggressively, then pointed to herself, then her legs.
"You... you did this?" She nodded. "Well, I know you did this when you took- wait no." The transformation stopped. Why would it completely stop and then start again abruptly? She isn't talking about the initial change, she is talking about the current one only. She was looking at her hooves when the transformation happened, and it only affected her limbs.
"The transformation... is being held back by your humanity. If you feel or act less human... more transformation can slip through?"
She nodded vigorously. Oh geeze... that poses a problem alright. That means there is no defined ending point- she could potentially go full cow if she slips up. You have an idea to help her feel better about her hooves though at least. If she feels better about herself, she should feel slightly more human, and thus be able to stay human better- presumably.
She looks puzzled as you walk out for a moment, telling her to wait. You return with a few items and then she lows in surprise as you lift her off the floor and plop her back onto the bed. You help her lay on her side on the bed- if she is off her hooves it will help her feel more normal a little. You get her to roll onto her back and her udder squishes out wider to fill her crotch while her breasts divide, creating a landing strip between them. You gently take her hind hooves into your hand to examine them closely. The scratches are very small on their surface and cannot be seen normally- they are only visible in how the light reflects off them. Rubbing your thumb across the hard surface though, you can faintly feel them. Her bones are tiny compared to a cow, so even with almost fully bovine legs; her hooves are incredibly dainty for a cow. You massage the skin around the base of the hard segments, and the little dewclaws in the back. Shaped like an animal, her feet still look so womanly and pretty.
"When you initially transformed, your hoof segments were probably soft, like a newborn calf. It did not take them long to harden fully, but since you were on them the entire time, it was long enough to get them a bit scuffed. But we can take care of that easily enough."
You take out a cloth and a tub of wax and start to rub her hoof firmly. The wax will wedge itself into even the tiniest of cracks to fill it, and since it's translucent, it will just look like whatever color the surface already was. She looked at you with a neutral expression, but you could tell from her eyes that she was enjoying this and thankful. She was also looking through the valley of her own cleavage- if her breasts sat on her chest when she was laying down the same as when she stood, she would not be able to see you over her own endowments. Her udder was relatively contained in her groin and also her thighs flanking it, but her breasts only balanced on her chest. Without being pulled out from her by their own weight, her breasts are extra jiggly in this position and jostle around with even the slightest movement. When you finish waxing her hoof to a glittering shine, you then take out some of her nail polish and apply a clear polish to the hoof. Once it dries it will form a protective layer of shine to make sure no new scuffs happen. You then repeated the process with her other hoof. You almost accidentally get a little wax on her skin when her hoof moves abruptly! There is a groaning again from her bones and she cries out from a rapid-fire series of cracks and pops and her last changes invert! In a matter of moments she returns to her initial cow-half form, once again able to stand on two legs! She doesn't move at all when changes start, because the muscles are changing and become unresponsive to conscious input till it is finished- otherwise they might get tangled in the shuffle. Even when you cannot hear a socket shift and re-set or a bone changing position, you can see it as an abrupt jostling in her body. Everything is built around her bones, so when the bone moves so does everything else.
"Huh... so you can turn back? This form seems to be the one you are forced into- any additional changes can come and go according to what happens to you? Gosh, I wish you could talk Lala... I know nothing about alchemy."
She just pat your head with a fore hoof, as if telling you it is okay. She knows you don't know. You both just have to figure out a way to deal with the cards you're dealt.
"Does it hurt bad when that happens?"
She shook her head. The bones straining and popping sure sounds like it would hurt- and she always cries out as if being hurt. Her cries are just those of surprise though; the nerves change with the rest of the body, preventing the process from being painful. Lala's cries are also the only way for her to communicate to you that anything is happening, since she still cannot talk.
When you are done, she sits up, perched like a gargoyle again with her knees up beside her tits and her arms in front of them. You grab a different bottle though and hold up the magenta nail polish.
"How about this one for the fore hooves?"
She grins and offers you one. You have never painted nails in your life- and neither of you have ever attempted to paint a hoof, but you can't imagine it being too different than painting a barn. You do have to be a little more careful with this polish than you were with the hind hooves, because this isn't clear; your mistakes will be much more visible. She isn't going to be walking on these ones hopefully, so you end up painting the bottom and back too, just encapsulating the entire hoof segment- and even did her little dew claws. You suppose the two dew claws are most likely what remain of her former thumb and pinky.
Once you are done, it is time to dress up your little cowgirl. Socks seem impossible, because if she walks around in them for more than a few minutes her hooves will just cut through the fabric. So instead you find some cozy leg warmers- charcoal grey with rows of royal purple hearts at the top and bottom. You slide them on to keep her legs warm. For tops, there is only one option that could possibly fit all four breasts. There is a beige colored wool sweater she loves to wear around the house in the cooler seasons. She shoves her entire legs up into the body of the oversized sweater too, so it's completely stretched out of proportion... which means it actually fits her normally now. Sleeves are too long- you can only see the very tip of her magenta hooves peeking out the ends but that is fine. Her larger top breasts squeeze the fabric outward, leaving a very generous view of cleavage up top- her lower breasts are completely hidden thanks to the slope the top create in the fabric. You give her a skirt to wear since it's the loosest thing she can put around her hips. You make sure to lift her udder for her while you slide up the waist, so the udder flops fully over the front of it. The skirt is always fluttering around thanks to the movement of her tail under it.
For the finishing touch, you give Lala her favorite accessory; and the most unusual one she has. It is a shackle meant for imprisonment, except it is three times too large to hold a human. Her family has a lot of tall people in it, which is why she is pretty tall for a woman even before she transformed. Well; her family explains this with an old tale of their ancestor having a forbidden fling with an imprisoned Giant. That is where the shackle comes from- it's an heirloom. You both really doubt the story is true- no one in her family is nearly large enough to be called a half-giant, but she loves the shackle all the same. Lala wears it around her neck, but it is so huge that when she tilts her head down the shackle covers her mouth and nose, allowing her to hide behind it. The shackle never needs to be opened- it fits over her head easily. There is only a single chain link dangling at the front of it. An odd thing to ever wear for sure- but it is a great conversation starter, and it gives her comfort, so it seems appropriate now. Maybe you should hang a cow bell from the front link? Hah, nah. You are trying to make her feel more human again, that would do the opposite. Well there. All taken care of for the time being. With a pat on her head you two go about having as normal of a day as possible.
The ranch is so far out from Andeva proper that no one is going to see her even if she is out in the field all day. Lala disappears for a bit and you end up finding her climbed up into the apple tree, laying down in its branches slowly eating an apple held between her two hooves. The shade of the tree is cool, but she can still feel the light on her skin filtering down from between the leaves gently fluttering in the brief breeze. Cows gather at its base as well to laze in the shade. It is not too hot out, but if you stand directly in the sun you'll still cook out here in the middle of summer. That sweater she is wearing is far too warm for this weather but it is the only thing that would fit her properly, and luckily in the shade her tits stretch the fabric far enough off her that it isn't too bad. You wonder what the cows think of her now that she is half cow herself, but they don't seem to notice- they haven't reacted at all. Lala is probably still too human for it to register with them. You notice bumps on the front of her sweater... are her nipples erect? In this heat? She doesn't look aroused.... eh, you shrug it off for the time being.
You hear her lowing outside as you are starting to prepare the food to cook for dinner later, and it takes you almost three full minutes to realize she is deliberately being loud. She isn't a cow, she isn't mooing just for the sake of it- she is trying to get your attention! You glance out the kitchen window but she is not in the apple tree across the field. You go to the front door and out onto the patio and spot her trying to make her way back to the house, but having a tremendous problem with it. She is... waddling almost seems too generous a word for it. She can barely move at all, and it's obvious why. Her top is stretched absurdly gigantic by all four breasts- now yanking the top so far out that you can fully see the top and bottoms of her top and bottom set of breasts- it only covers the middles of both sets. Her nipples have grown massively- now the length of a middle finger and the girth of a silver dollar, you can see their bulge plainly on the sweater, bent sideways around the curve of her breasts from a complete lack of room! The entire front of her top is soaking wet- without a doubt from milk. Even more distressingly though is the monstrously huge wrecking ball of an udder below her. It is so massive and heavy that it does not even really swing when she moves, it just jostles a bit, anchored by its own weight. With her legs spread as wide as they can go, her inner thighs are still pressed into the side cleft between udder segments, and the bottom of the udders is lower than her knees- not even including the gigantically fat, bloated teats lower than that! Each teat was the size of a beer can and dribbling milk constantly! Even the veins on the surface of the udders were tremendously thick, and created a dense maze toward the top of the udders in the looser connective flesh.
Lala needed to be milked, which is a very cow trait. Women can lactate too, but they can also milk themselves- cows can't. So what happens to her when she is more cow in relation to her mammaries? They grow. And their default size was already big. She actually has a higher milk capacity than any cow- because the 50/50 trait split caused her to have four breasts with the combined size of an udder, but also get the udder on top of that. So she is like a blue ribbon dairy cow that somehow has TWO sets of udders. You immediately go out to help her and almost try to lift her, but quickly second guess that idea. You can pick her up normally, but uh... currently she weighs like 5x the amount she normally does- you aren't lifting that. You put her onto one shoulder with your arm under hers on the other side of her body to try and take as much of her weight as you can. You still have to move very slowly though- her legs cannot move normally while pressed into her udder flesh. Once inside you put her on a kitchen chair and move to milk her. The kitchen floor is tile, and it's the first room through the door to the fields. You don't want to go back out to get an actual milk pail and leave her dribbling on the floor in the meantime, so you just put an empty jug on the floor to milk her into the best you can and let the floor take the rest you suppose. Your priority is relieving the pressure and reducing her gargantuan size. You have to wiggle the sweater around quite a bit to finally wedge it off over the breasts- though it comes off easily once one breast is out and the fabric can relax more. Her teats flop all over, but bounce back to fully standing out off her breast like someone wacking a door-stopper. They are erect entirely by milk pressure. Her areola are even stretched smooth from the load they are holding back, and pop out of the surface of the breast in their own half-sphere. Because the areola are stretched across even larger breasts now, their edge is an even more gradual fade than before. In this enlarged state, her areola alone are about the size of your entire face!
You grab one fat teat in your hand, steady yourself on the chair with the other and press your face into a firm tit with the other. Her breasts are like a balloon full of water- their surface pulled tight and smooth and so rubbery and elastic from being at max pressure. You can tell it isn't a pleasant feeling for her by her expression. It is probably like an overfull bladder... just, on her instead of IN her. And also there is eight of them. It is insane that she let this happen without coming to you sooner, but in all likelihood Lala fell asleep in the apple tree. This happened while she was sleeping, and she only woke up because of the discomfort of being beyond capacity.
When you take the huge nipple in your mouth it already starts to jet as soon as you close your lips on it, before you even suck! Milk forms around your lips and runs down the bottom of the breast as well- the areola itself is also leaking steady beads of milk and there is no way in hell you are getting her entire areola in your mouth. It definitely isn't like cow milk. Even straight from the tap it is only as thick as a coffee cream, and has a slight sweetness to it- in spite of her cow traits, she is still producing mostly human milk. The teat on her udder that you grab; you do not even need to tug on- it's only that thick because of the milk it's storing, so as soon as you compress it in any way, the milk explodes out. Her nipples blast several thin streams in random directions into your mouth, but her teats erupt a single massive jet like a garden hose. Lala moans loudly for as long as you grip the teat, and moans softly for the sucking on her nipple- between the two she is unable to catch her breath and pants breathless and rapidly. She looks almost dazed- the pleasure is probably overloading her brain entirely. Her nipples and teats are sensitive and like being touched normally- now they are being touched and tugged on the outside, but also have a solid high-pressure stream of liquid tickling the inside as it erupts outward, on top of the relief of the pressure on top of all that. Lala squirms in her seat from the pleasure, and you quickly switch between which nipple and which teat you are working. Above all else you need to get rid of the overpressure, so there is no point trying to empty any single one of them. All four segments of the udder and all four breasts have their own supply, so you need to tend to all eight to balance her out.
The milk dribbles down your face, neck, and drips off your chest- you cannot help it, if it leaks from the areola you have no way to contain it all in your mouth. When you first start milking her udders, pulling on literally any teat will also cause the others to express as well, just at a third of the force, because the udders are so full that any pressure or movement at all causes it to come out. You decide the best way to immediately get the pressure off is a less direct approach. You clap your hand over the divot in the middle of the udders making a very loud clap and causing her to cry in surprise, and then you shove inward. It tugs on all four segments, all four teats stand up and start to spray at the same time! You can feel her heart beat clearly in the soft flesh of the udder. It is so massive you bet the only way you'd be able to cover the entire udder is if you curled your entire body around it. If the chair she sat on didn't have metal legs it would have exploded the moment she sat down from the weight. Even these metal legs groaned when she sat, grinding hard against the tile under them. You reposition yourself in front of her and she blinks in confusion a moment, catching her breath a little bit- her chest still heaving. You take a huge nipple in either hand, pull them together, and then bring your head down and suck both into your mouth at the same time! Because your leaned over, you place your hands on the top of her mega udder to balance yourself and deliberately bounce yourself up and down on it, causing the udder to slosh a bit and milk to spray out all four teats every time to you push down before letting it spring itself back up, fighting your weight with its tension.
Your own stomach starts to ache a bit from the sheer amount of fluid you are drinking from her, but its addicting. The hot, sweet fluid tastes good, and her tits feel so good to play with in your mouth, and her boobs so soft and supple to press into your hands and face. Her moans of pleasure, her heavy breathing, the thrum of her heart beating in the fat veins. You'd rupture your stomach and take a trip to the ER to live in this moment a bit longer. So well beyond filling yourself normally you continue to drink. The jug you brought out filled to capacity from only a single udder segment, the floor took the rest and she flooded the kitchen, but you were more concerned with saving her from her out of control body, and now more concerned with reveling in the moment. The milk spilling from the top tits that you could not contain dribbled down their round undersides and pooled in the cleavage of the bottom breasts. Once the liquid pooling there became heavy enough it trickled down through the cleavage, filled her belly button, then cascaded down the cleft of her udder and onto the floor.
"Mm... mmmmuh~ Oh... ouhn... Moo! M-m-mo-huuuoooo~!" She started to sound a bit frantic and distressed.
You let her teats flop out of your mouth a moment to look at her, and she looked surprised as well as lusty. She moaned loudly, and her pitch immediately spiked! She thrust her udder forward and arched her back painfully far over the back of the chair and all four nipples and all four teats absolutely erupted in milk! Her breasts and udders started to pulse; clenching and... shrinking! She is returning to her default cow half again... except that means she no longer has the same capacity to store milk! Her shrinking is forcing all the milk out from lack of room! Each nipple sprayed in eight different directions at once like a sprinkler, while you could side-step to avoid the four streams her udder sent onto the floor. There was so much liquid coming out of her at once it actually sounded like someone with a garden hose on full blast spraying the floor. She convulsed in her seat, having an orgasm just sitting there, and moaned continuously so long you were worried she would black out from lack of oxygen. After a full minute of non-stop streams of milk, her menagerie of mammaries finally emptied and returned to their default size- big lower breasts, bigger upper breasts, and a... relatively small udder.
You nodded to her, panting desperately to get her breath back as if she just ran a marathon like it was a sprint. "I'll get the mop." Both of your clothes were absolutely soaked, and there is an inch of milk across the entire kitchen.
You actually felt a bit woozy after that, and ended up skipping dinner entirely that night because you were still so full from the milk. You were really absent minded the rest of the day and feeling stiff. You really can't drink that much milk at once- her output was insane. As usual, you both got into the bed together after the sun goes down. Neither of you stay up late because the cows will need milking early morning as soon as the sun comes up. You suppose it would probably be a good idea to get Lala in on a regular milking schedule too, but neither of you know how quickly she fills up yet to know how often she needs to be milked. That serum isn't going to wear off any time soon most likely, so you'd better get used to this; this is life for the next while. You look over at her before closing your eyes and she surprises you with a kiss- she was already looking your way. Because of how her nose changed shape- the end of her nose is perfectly level with her upper lip, so she cannot kiss you without also booping you with her nose. You kiss her back and both of you go to sleep.
It is your turn to milk the cows, so when Lala doesn't want to get up with the alarm you just leave her be. You do lift the blanket to get a look at her breasts to see if she is increasing in size again, but they look alright. A shade larger, and the udder looks like it might be getting full but neither have actually grown yet. You grab a coffee and head out to milk the cows. You are still really absentminded today and find yourself zoning out while milking, which you suppose isn't that bad- helps it go by faster. You keep remembering milking Lala the night before. Her udder was just as big as these full sized cows, except attached to a human torso, and accompanied with four giant breasts. Lala has the cows beat from every angle. After milking the cows you don't feel too worn out. Usually your hands are cramping up pretty bad by the time you are done. So rather than go in for another coffee you decide to try and clean up some of the mess Lala made at the back when she transformed. She is lucky she did not get pinned under some of the equipment she knocked over- Lala must have been flailing around quite a bit in confusion to make that big of a mess.
It is an easier mess to clean up than you would have thought. Some of the crates fell over and you figured you would need the forklift to get those back up in place, but you actually try with your hands beyond your own logic and DO it! You manage to pick up one side and shoving it against another crate for balance, get your hands to the middle so you can balance it better and actually manage to lift it up. Damn... you are a lot stronger than you remember. Guess ranch life is finally beefing you up, haha. You glance at the clock above the main barn doors and then back at the house with a furrowed brow, wondering why the lights were still not on. Was Lala actually still sleeping? It is past noon already!
You return to the bedroom and sure enough she is still sleeping. "Lala, c'mon get up. It is late in the day. We have enough to figure out about how to do things now without you messing up your sleep too."
"Mmmm..."
"Lala." You pull the blankets back to reveal her upper body but she just groans and scrunches up before rolling onto her back to look at you.
"Mmm... mooouuu... ooo... oo? M-muh!" She moaned and lolled her head back a moment with an odd look on her face.
Her aqua eyes had a vacant look to them rather than their usual brightness, and her mouth just lolled open a moment before several cracks sounded out from the bones in her skull! Her laziness is bringing out more cow! The human aspect of her mind is shutting off for the blissful ignorance of a bovine! Her face started to push out, slowly growing a muzzle! Her neck throbbed, then grew a tiny bit longer, then pulsed thicker, then longer again and kept alternating! Her entire skull was increasing in size, making her head disproportionately large to the rest of her body! The skin of her neck grew even faster than the neck itself, starting to pool into thick folds as she developed soft dewlaps!
"Uhhhnnngh... MUH. Mooouuu~ooh OUUUUUU!" The pitch of her voice dropped quickly to a thunderous low she wouldn't even be capable of normally.
Her head continued to crack and snap, deforming worse and worse, looking more like a cow and less like Lala. Her skull was becoming a rounded triangle in profile, but rectangular head-on. As it grew and the skin stretched, her beautiful long hair started to fall out, taking still more humanity from her. You quickly hustled to the side of the bed and got on over her. You take her shoulders a moment and shake her, as if to try and wake her from a dream.
"Lala, snap out of it. You are Lala, my wife."
"Muh?"
You glance at her and in the moment you feel oddly aroused. You grab her top left breast and dig your fingers into the rubbery flesh. You grab a handful of her soft dewlaps with your right hand, kneading it a moment before pulling her head up by it and kissing her. Your large tongue nearly as big as her fully bovine tongue- invading her mouth and entwining around hers. She moaned and her expression scrunched up a bit. When she opened her eyes again they were crystal clear again, and quickly the sound of shifting bone was heard again as the changes reversed after only manifesting moments before! You kissed her deeper and deeper as her skull shrank and her face compressed, as if you could shove her head back into the correct shape with your lips. You pull off when the transformation as settled and let her catch her breath. She sits up with a bit of a dazed expression and then flinches a moment and bows forward as thousands of little hairs poke out of her scalp! Her hair all fell out when her head went full cow- luckily it seems like it is going to grow back rapidly to replace itself now that she is human again. It actually looks pretty cute as a short bob, then it touches her shoulders and rolls on past to her upper back before it starts to lash out in random directions- long enough that its huge loose curls return. But then it kept growing, and in spite of the curling and waves it surpassed her lower back... and then touched the bed, then started to pool on the bed, fan out, and spill off the sides of the bed! As if trying to make up for having fallen out in the first place, her hair was now so long that it touches the ground even when she is fully standing, and curls at the end into loops so large a child could crawl through them! You aren't quite sure, but it sort of feels like you two came out on top on this one. But you also know now to make sure her mind doesn't start to wander, or her head will go with it.
You discover yet another possible change at breakfast. She seems very hungry, which is understandable- but she eats more than you thought she would be able to in one sitting, and then her ribs pop in rapid fire and her chest starts to grow larger, putting more space between all her breasts! She started to rise higher in her seat as her spine got longer and her entire torso more barrel like, becoming bovine in shape, but pausing before it actually grew in mass. She looked very awkward sitting there like that, because changing her torso shape prevented her from bending her body normally- it basically forced correct posture on her. Luckily the cure for that change was simply cutting Lala off from any more food, and as the excess she already ate digested, her body returned to its normal shape.
The rest of the day went by relatively uneventful, till late in the evening. Lala motioned to her breasts once you both finished eating, then to emphasize she put a hoof on either side of a nipple and very easily squeezed out a drop of milk. Ah, she is full again. Normal full- not grow to titan sized full. You brought in actual milk pails this time, so rather than be on the firm chairs of the kitchen, you brought her back to the bedroom and sat her on the edge to be milked in comfort. Even flopped over the edge of the bed, you still need to bend her teats down a bit to make sure the stream gets into the pail without splashing. You pet the udder before sliding your fingers to the base of the teat and tugging forward to release more milk. Rubbing the udders is good to calm the cow, and make expressing easier, but in this case Lala needed no calming; you were just doing it because it felt so good to touch such exquisitely soft flesh and you knew Lala loved it too. She liked having her nipples and teats pulled on even when she was totally human, so now that they are so large you can do more with them without worrying about hurting them, like nibbling on them or twisting them around. She loves having her tits kneaded. Once her udders were empty you turned to look up at her breasts, but she was bent over watching you work her udder so when you looked up you got a face full of tits! Your face was planted in the canyon between all four breasts, surrounded on all sides. Rather than just pull back you shake your head, causing the breasts to bounce off and plap against your head over and over and Lala giggles, takes the back of your head gently and rubs her breasts up and down, leaving damp trails on your shoulders and chest of your shirt. You lick her chest in the crevice between- it is salty- her breasts are well insulated so the crevice between is the first place she starts sweating if she gets too warm. It does not even occur to you at the time that licking her like that is a bit odd. Lala thought it was odd, but did not mind at all.
Instead of getting a third pail to start milking her breasts into, you just thoughtlessly latched onto one of her large nipples. She again cradled the back of your head and started to lay back, guiding you to get onto the bed on top of her, and so you do. The bed dips really low- the springs groan with your weight. That is odd, she hasn't grown any, the bed should have no trouble holding you two up like it always has. You suck onto the nipple so hard that when you pull back the boob stretches out to follow your mouth before it finally pops free and wobbles back into place, squished against her chest under its own weight and you go back down onto it for more. Even though it sticks out as if erect, her nipple is very soft and fun to flick around in your mouth using your tongue. It is also sexy as hell, drinking such hot, sweet fluid from your wife's abundance. So much supple breast flesh and all offered to you alone.
Looking at them really close you notice that even the lower breasts have freckles across the top- though usually overshadowed by the top breasts, and impossible to see on the lower right breast since the entire boob is brown. That means she developed freckles in a place she didn't have them before, so her breasts would match. You look at the freckles when you suck on her breasts, trying to connect the dots in your head to spot constellations on her flesh. She softly moos and lets out satisfied sighs. You see her legs squirm a bit and her tail thrashing around to her side- she is aroused by this too. The head of your penis is pinned under the waist of your pants- any longer and it would pry itself free of your pants on its own. Your balls feel unusually heavy- they are doing pull-ups in your scrotum in slow motion. Clenching and lifting slowly, then release suddenly and flop back down- but when they plop back into a full rest you can feel the entire scrotum tug away from you from their weight! After drinking from three of her breasts you start to feel full but not in your stomach! Your balls feel unusually heavy and full, you had sex with her just the other day but it feels more like you've gone a month without- like an ocean of cum is ready to erupt if someone so much as blows on your shaft! By the forth breast you are humping the air over her occasionally without even meaning to. You barely notice yourself. Your body feels like it is glowing hot from the pent up arousal and your thoughts are a rush of pink, moist flesh.
Lala takes notice though. Once you had her last breast to at least half empty, she gently pushes you off and starts to squirm around to get onto all fours under you! You sit up and she quickly makes a beeline to your lap and unzips your pants with her teeth! She lets out a surprised moo, and then licked her lips and let out a sultry moo at the sight. You are so focused on her you do not even think to look at what she is so impressed with. Each testicle the size of a softball, and the scrotum grown longer to accommodate without becoming tight- though a bit of excess flesh also pooled at the base of your cock. She uses her long cow tongue to coil around your shaft and lick it from head to base several times before taking it into her mouth! Lala's moist pink nose booped your crotch as she swallowed your entire cock and her nostrils flared for a second as she took a deep breath of your musk. Her tongue lashed out every time she got to the base of your cock, cupping your balls from below before slithering back into her mouth. She hums a few times and pulls back further than she should be able to without taking your cock out of her mouth! It looks like her mouth is stretching your cock longer! It's getting longer but also more thin- the glans starting to lose their shape, like she was licking away a lollipop. You must be amazingly aroused to think such things were possible, but you were also in too much of a horny daze to question it. It only took her a minute to bring you to climax, and you thrust into her mouth and accidentally bumped her throat! You realize in the moment of orgasm that your dick is only partially in her mouth- it's so long that half of it is in her throat! You are also erupting so much thick cum that you can feel the flow through you, and there does not even seem to be a pause! Lala is forced to swallow many times over, and half of it goes down her throat without her even thinking about it. You cum for what seems like an impossible 2 minutes straight before stopping. She pulls off and you are both panting to catch your breath for a bit. That was the biggest, longest orgasm you have ever had.
You both look to your crotch after the moments of rest and see your cock is in fact a bit bigger, but its shape has not changed- it must have been an illusion of your lust. You also notice that it isn't even beginning to get soft. You came very easily, but your dick also does not seem to be ready to throw in the towel. She smiles and scrunches herself up into her gargoyle pose before slamming into you! She pounced on top of you, knocking you flat on your back!
"H-hey, watch those h-hooves..." You furrow your brow and try to clear your throat- your voice is unusually deep.
She climbs over you, then stands up on the bed, giving you a prime view of all her many soft bits. She then turns around with a hoof over either of your shoulders on the bed, and immediately sits down! She plops her soft, wet meat right over your mouth and fills your nose with her scent. You cannot see what she is doing past her rump in your face, but you feel her udders roll forward and squish against your chest. Then the nipples and then lower breasts press into your lower stomach. Her massive top breasts squished against your crotch and completely filled the space up to the base of your shaft before her lips once again took your cock into her hot, inviting mouth. You hear a few muffled pops from her hips and they shift slightly. Her pussy seems to open entirely on its own as if it were yawning before the muscle ribs in the vaginal lining expanded, swelling the passage tight again! Her clit throbbed larger, but was swallowed deeper into the folds as her labia also became meatier... her vulva grew into a leaf-shaped bovine one.
Now almost large enough to swallow your entire face, you dig your tongue between the moist lips and surprise yourself with how far it can go, penetrating her on it, making her squirm. You can feel her tail whipping around in the air over your head, because the hair on the tassel is so long that it's dragging on the bed still. When your balls clench and roll back to your crotch, they bop against the top of her nose. Lala is devouring your shaft like it was delicious candy- you can hear the single chain link on the shackle around her neck jingling from the rigorous movement. You pause your licking and grin a moment as her butt trembles with muscle spasms as you bring her an orgasm of her own, and her hot salty juice drips onto your chin and neck before you resume eating. Does this count as beef tender loins? Still tender from the last orgasm, it isn't that hard to work her toward a second. The end of your tongue swirls around her passage and you bent the base to crush the passage up toward her clit, making her start to tremble again. You reach up around her legs and yank on two of her teats, pulling her hip down on your face harder, and started to sit up a bit- lifting her entire back half up by your face! She hummed some distressed moos around your cock in surprise! Lifting her back half forced her to go down harder on your cock- she was not ready for it so when you came blasting cum into her mouth, her cheeks immediately puffed up like a balloon and cum erupted out her nostrils before she realized to swallow! You were so tired after that, you two just rolled apart and fell asleep- which means you were sleeping on the bed upside down, with your feet at the pillows.
When you wake up you see Lala slap the alarm clock to shut it up since your arms aren't close enough to the table. As usual she does not actually open her eyes for a good minute or two after the alarm went off so it's sometimes hard to tell if she actually woke up. The blankets only cover one of her legs, so most of her body is on full display- her pale peach skin practically glows in the morning light filtering through the thin white curtains over the window. She is turned toward your side of the bed, only half on her side but it is enough to cause her left breasts to sit on top of her right ones. Her udder looks larger, but not full. You wonder if there is some other condition that could cause her mammaries to grow besides milk? The size difference isn't that big, so it doesn't seem that concerning at the moment, and you are honestly more mesmerized watching the tranquil cowgirl. The hair on her head and tail fan out across almost the entire top part of the bed. Her hair was already wild after a night's sleep because of how long it was- now it is five times as long and able to form a mat across the entire bed. When you sit up, you brush some hairs out of her face, off her moist neon pink nose. Lala smiles and hums- still not opening her eyes yet.
As you shift over to the side of the bed, the springs groan and grind together and sitting on the edge of the bed to stand up causes her side of the bed to lift up almost far enough to roll her into you. Damn, bed springs suddenly go out? The bed is kind of old at this point, probably need to replace it, because it had no trouble holding you two up before. You try to get dressed but your damn outfit feels tiny? What the heck, the clothes must have shrank in the laundry or something. You are about to complain to Lala but then try to recall who did the laundry last, and cannot. You don't want to bring it up accusingly only to remember you are the one who did it. You just leave the outfit out on the floor and instead pull out your own most oversized clothes and pull them on. They seemed to fit fine. How many of your outfits have been shrunk?
You grab your morning coffee and start to wander to the barn to milk the cows. It is halfway over to the barn you pause and try to remember if you had a shower this morning, you smell a bit musky. After doing it every day for so long, that would be a really weird thing to just randomly forget entirely. You cannot remember if you showered, but you are already by the barn, so might as well just forget it for now. When milking the cows you are incredibly absent minded, and have a persistent boner. Damn Lala; now every time you milk a cow you keep thinking of Lala's massive endowments and milking her. You snap out of it a few times randomly, catching yourself petting or downright fondling the cow udders as you try to do your job. The cow's certainly have no complaints. The stool sort of hurts your butt after a while and makes your legs tingle from lack of blood flow. The stool feels harder than usual? Or like you were heavier. When you finally stand fully up after the last cow is milked, you stagger back a bit and look at how unusually your shoes fit your hooves.
Why do you even bother wearing shoes if you have hooves anyway? Wait. Yea! Fuck these silly things. You kick the shoes off your cloven hooves rather easily- your socks have holes wearing in them too because the edges of your hoof segments are cutting through the fabric, so you just get rid of those too. It feels so much better to walk around on your bare hooves anyway.
Like the other day, you do not return to the house after milking- you still have plenty of energy. A ton of energy, actually. You probably did not need that coffee this morning. There is no mess to clean today, so instead you just grab up some equipment and use them as weights, till you work your way up to deadlifting the storage crates at the back- which normally require a forklift to move. Your muscles feel so... tight and so... big! It feels great. You can almost feel your heart beat through your entire body from your veins swelling up fat all over. After a while you are sweating quite a bit, but do not care. You like the smell of your own musk, and some of the cows are watching you now; so you think they like your smell too. Your muscles swell taught, pushing against the firmer seams of your clothing. You hear a rip form suddenly as you become a bit too big, causing you to pause in surprise. Damn, you did not think weight lifting for one morning would make THAT much of a difference. But in your pause you see Lala grinning up at you and you slowly put the crate down and glance at the clock. Oh- that is why she came out to see you- it isn't morning. You have been at this for over half the day already, zoned out- it is late afternoon!
"Moouuuuu? Mumoo, noo muh." She fluttered her eyelashes at you, her tail flicking from side to side in an exaggerated arch.
You smirk at her asking you to flex for her. You lift both your arms and do an exaggerated flex for your little cow but both your shirt and your muscles themselves make a stretching sound! Your muscles bulge almost obscenely, and you can feel a ripple down your body as you stand up straighter and your abs tighten and bulge out, pronouncing fat veins concentrated toward the base of your cock. Your tail twitches from the odd feelings and you groan in an increasingly deeper voice as your shirt tears in several places. The tears quickly widen, and again, and finally your shirt bursts right off! You have a dark mat of unusually soft black hair on your chest and forearms now... wait, hair... or fur? Muscles aren't supposed to be able to grow so fast!
Your heart skips a bit and your thoughts spin a moment, making you dizzy and several things occur to you that are extremely unusual, but you had completely overlooked. You just had a massive growth spurt, that is definitely not normal. Your pant legs are stretched taught around your muscular thighs and barely fit too. Your dick is pinned under the waist of your pants and it's still completely soft! Your underwear are completely filled with just your balls and nothing else! Also- how the hell did you know what Lala asked you to do?! She can only moo! W-well... you have been together for so long you can just tell what she wants sometimes... that is normal, right? You could also have just imagined it- there is only so many things she could have been asking with that look in her eyes anyway.
"Wouu-ait! Something no right... me not so... I am... too big?" You were about to say too muscular, and only just now realize that you are looking DOWN at Lala. She is supposed to be taller than you are. The top of her head is now only level with the BOTTOM of your chest! No wonder your damn clothes don't fit! "Moulk- mm- milk! Your milk! The empowered bovine hormmmones must be transmittable through your milk! Damnit Lala, you turn, your... you are turn me...? Ugh. You gave me some of your cow!"
Lala giggled giddily, clearly not at all disappointed with this revelation, but you just grunt at her, blowing her hair back a moment with a gust of hot air from your enlarged nostrils. Of course this lewd little Holstein doesn't mind- your now built like a stone fortress, giant, and your nuts alone are as big as her tits used to be before she transformed. This however means your body is now unstable... and you feel absentminded... and thoughts are become... slow. Her milk can't transmit the hormone in a concentration remotely close to her own dose, but you did drink an awful lot of it. Hopefully the changes stop here... and revert faster than hers. You need to look after her as well as yourself- if you turn too far then no one can be looked after! You want to look after your herd but she isn't making this eas- er... wife you mean, not herd.
You lead her back to the house- you need to start on dinner now. When you go to enter the house you end up cracking your head on the roof over the patio- never mind the front door, you can't even walk on the patio without ducking! Your muscles feel... anxious? You want to flex them, stretch, but... you don't want to unintentionally encourage any changes. You start cooking the meat and move to making a nice salad to go with it, while Lala stares at you from her seat at the table- she is mesmerized by your new form and hasn't left your presence. You end up popping a leaf of lettuce into your mouth or a cherry tomato every so often as you prepare the salad... causing it to take much longer than it should. The level of salad in the actual bowl doesn't change because you keep eating it! Your leaf shaped ears flick up and Lala's tuck back from the harsh sound of the fire alarm! You look to the stove to see smoke billowing up from the burnt meat! You spaced out and took so long on the salad you completely forgot about the meat. Well, no meat tonight now, Lala, hope your happy. By the time you finish fanning the smoke off the fire alarm and look back- she skittered across the kitchen and ate what little salad actually made it to the bowl before you could eat it all. Hrrmm. But you are still hungry. But so hard to think straight... you really don't want to try and cook again tonight.
Guess you will just go a bit hungry. You watch television for the rest of the evening, though you are spaced out most of the time. Occasionally there is a scene with enough action to snap you out of it, and then you confuse yourself trying to remember what lead up to that scene only to realize you must not have been paying attention in the first place, and then your thoughts wander while trying to remember and you zone out again. The couch is also uncomfortable. The cushion you are sitting on basically folded in half under your weight- you could faintly feel the springs through it because your body is shoving down against it so hard. Lala snuggles up close to you, that makes things a lot more comfortable. She nudged your arm aside to squirm her way under it, and softly traces the contours of your abs and crotch with her hooves.
Your eyes immediately look down to her on you when you feel her fat nipples flick out from between your bodies. She leaned back a bit to yawn, which angled her tits enough that her nipples escaped, and flicked little beads of white across your abs and onto the arm of the couch. Oh that is right- she needed to be milked by this time the other day. She is probably getting full again. You gently put a hand on either side of her chest and she looks confused a moment and then immediately giggles as you lift her off the couch like she was a doll, sit her own on your abs while licking your lips- your eyes locked to the dark red-brown nipples, fat with hot thick milk. She drags her pussy on your abs, smushing her udder against your lower chest and thrusts her lower nipple into your mouth. You greedily start sucking her sweet milk, letting it coat your mouth before swallowing.
Her taste so good, sweet... taste like Lala. Oh! Your eyes widen and you pause a moment realizing you are drinking more of the hormone as well! Oh no, but... you're so hungry too, and Lala... so pretty... soft. A little more won't hurt. It only did this because you drank so much. A little bit is nothing. Just a little bit more, to fill up. Just a little more. Just a... more.
You start sucking so ravenously that some milk dribbles down your chin. When the flow slows you immediately switch to the next nipple. Your muscles feel so warm... so... tight, no, that isn't normal... they are pulsing! They swell tight and expand with a faint stretching sound, then relax, then do it again! This time the growth is almost entirely muscles in your upper back. Something else too? It is hard to hold her sides, your arms feel a bit tingly. You are surprised by a sudden pop and your hands are forced further forward, past her body. They don't quite want to bend correctly? Your fingers feel stiff, your hands unusually long? Oh no, your hands might be turning to hooves!
You need to stop drinking, but you hum a muffled moan against her tit flesh as Lala manages to catch the zipper of your pants on the crook between her two hoof segments and unzip your fly. The pressure your huge nuts put on your pants caused them to billow out and pop free almost entirely on their own! Your dick already looked hard, but it felt like you were still getting an erection! You could feel the blood rushing into it, the pressure and tension rising still! Your dick throbbed a bit fatter, but mostly; it stretched slowly longer! She used the flesh between her four hoof sections on both limbs to rub the base of your cock, watching it past the right side of her right tits while you drank. You were experiencing too much pleasure to muster the strength to push her off, and she was shoving her tits into your face to drink so you could not take your mouth off. You either drank the milk or choked on the milk. You groan and push up through her two-hoof grip and watch as your cock stretches beyond the foreskin! When you push up her grip holds the foreskin back, so you grow longer beyond it, making it look a bit out of proportion. You notice the hair around the base is advancing up... no, too dark, too soft looking, it's fur! It starts to creep up your shaft like a growing shadow. Your balls are each the size of an oblong cantaloupe but your scrotum is still disproportionately large compared to them! You have almost a half foot of empty scrotum before your balls- so once they start jostling around they end up rolling right over the edge of the couch. You still see their tops over the edge as they clench and rise up.
Just a bit more muh... milk. Make cock grow! So big, so good! If you drink up your cock will become huge and then you can stop. If you have to be a part bull mutant you might as well be enough bull to experience the advantages, right?
The shaft only grows beyond the foreskin now, and the skin on the base pulls tighter to your body, and then starts to fuse up! The fur spreads right to the top as your foreskin finishes its transformation into a sheath! Lala moans and you notice she is panting even though she is mostly the one giving you pleasure, but you see why soon enough when you need to try to pull your head back as far as you can! You have to shove your head back against the couch hard, to avoid her breast flesh from blocking your breathing! Her breasts and udders are growing, the tit flesh expanding around your face as you drink from her! Her udders are pressing into your side below so while you cannot directly see them in this position, you can FEEL them grow.
Your cock rises higher and higher, but as it stretches the glans are pulled tighter and lose more and more definition against the shaft, turning it into a tapered pillar! Drips of pre followed a strand already connecting your cock to your stomach, and pooled between your rock hard abs! The veins in your cock throbbed massively, feeding more blood in to the engorging monster. It was so long Lala could reach it with her mouth if you left her breasts without needing to change positions, but still it grew. It became so long she could suck on it even leaned over to you, without needing to bend over- just bend the shaft, and so she did. Since the shaft is tapered she can easily take it into even her throat, and swallow a seemingly impossible length of neon pink meat. Your balls started to clench hard enough that they actually bounced over the edge of the couch to touch your crotch, and then fully roll back off the side. You feel her mouth tremble oddly around your shaft and her sucking pauses for only a moment. You look at Lala over the top curvature of her fat tits and see her face has pushed out- she has a demi-muzzle! Your worry about your devolving hands flashes back into your conscious thoughts. You need to stop. Enough, dick is the full size of a bull. Need to keep hands.
You push Lala away, sliding her reluctantly off your dick- she looks quite disappointed. She was counting on a dose of protein from your nuts to make up for the no meat at dinner. You take several tries to be able to stand up out from under her.
"Touuu much bull. N-need uuuugh~!" The muscles in your upper back swell even larger, making your back pop and forcing you to hunch forward from the weight. Your hands are almost entirely hooves and your shoulder blades have already shifting. "Hard tooouuuu stand. Lala... me need humun more. No change, milk good... bull no... bull... mmm."
The muscle expansion surges, shoving into your arms, beefing them up still more before your forced to fall completely over and catch yourself on your new hooves! Lala gets down onto all fours as well and softly runs her wrists down the length of your scrotum, nudging the balls at the bottom to watch them swing like a pendulum- hypnotizing her. You unintentionally low like a bull as you feel her tongue lick up the backside of your scrotum, slow and increase pressure across your taint and then suddenly slip into your ass! She kissed your butt and started to give you a rim job- her moist neon pink cow nose pressed against you and her massive bovine tongue writhing like an angry snake inside you! Your legs jar forward as a loud pop sound s from your hips as the bones become much more pronounced! Oh no! You can't get up, you're a quadruped now! Your massive heavy nuts manage to heft themselves up even from a free-hang, rising a bit higher with every undulation of her tongue as she continued to nudge your nuts with a hoof to make them swing. Higher up they went, more pleasure. Cock dripping pre constantly onto the floor. Higher they rise, more tension, cock vibrating now under you without anyone even touching it directly. Can't hold on, she is too good. Your balls bumped your crotch, then drooped a bit, then slammed into your pelvic floor and held there as there was a full two second delay between orgasm and ejaculation because of how long your dick is! The volume of cum was tremendous but your urethra wasn't any bigger with this new phallus, so your orgasm went on and on, lasting nearly three minutes before you could stop. The changes, orgasm... Lala... too much, too tired. The entire house shook as you fell over onto your side right there and went to sleep.
You woke up slowly the next day, you could hear the alarm going faintly in the bedroom, but a glance at the clock tells you it has been ringing for a long time now. It is already noon. You cannot see Lala but you know she is not far away- you can hear her hooves clicking on the kitchen floor, and the chain link on her shackle-collar clinking as the moves. You try to stand up at first, but then remember your body can't do that anymore. Your flaccid penis looks like a long cone made of soft fat skin rolls- because your torso did not change, your sheath is not long enough to contain it all, so half of it is still outside all scrunched up and jiggly with softness. When you stand up your balls actually lightly brush the floor under you because the scrotum is so long!
Brain so slow... I need... we need to... something? Problem... something was a problem... something very important I needed to do... ugh. Thinking hard.
You stare at your fore hoof for almost fifteen minutes, the neurons in your brain sending delayed signals to try and put together a train of thought.
Transformed. Changed, because of Lala, she made boobs bigger. Cow... stuff, not for human. What... how much?
You furrow your brow trying to remember what your hand is supposed to look like. This is not it. Your hand changed- you remember that, it happened last night. But what did it look like before that?! What did your feet used to look like, in order for those shoes you kicked away to be able to actually fit?
Muscle grew- so smaller? Change to hoofs... tail? Did have tail? Clothes not work, uhm... did smaller?
You end up unintentionally looping back to thoughts you already had because you lost track of them. You know you changed but have no idea how severe the changes are because you cannot for the life of you remember what you are supposed to look like! Lala is also transformed- you know that- so that means you have no normal humans to use as an example. You have forgotten what humans look like! You move in a lumbering motion. You carry your body easily because of your strength but you can also tell you are extremely heavy. Each step rattles the furniture around you. You try to go through the doorway into the far side of the kitchen from the living room but take the corner too sharply and your small horn catches on the doorframe. This frustrates you, so rather than simply step back and go around you ram your head into the frame harder, and start to splinter the wood! Your horns quickly grow longer and larger, starting to bend forward for you to use as weapons and gouge into the wall! Your forehead starts to extend a bit and flatten and finally the doorframe shatters and you stagger forward a bit. Rather than be concerned you just smashed a hole through the edge of the wall, you feel proud for teaching the frame a lesson about getting in a bull's way.
Lala immediately looks at you and smiles. She has made an absolute mess of the kitchen trying to get food out without hands, and was eating some of what she managed to actually get up onto the table. Her hips are semi-transformed so she can stand on two legs but cannot walk on two legs. Her udder is once again at its mega size, but isn't leaking, so it seems to have grown without hitting capacity- also her breasts have not changed size with it. Her neck is unusually long and her face has a mini muzzle, and her genitals remained fully cow thanks to last night. Having her husband be more bull may be influencing her cow traits- generally only cows have bulls for mates after all. If that is true, you'd both keep progressing each other's transformation and make maintaining humanity impossible till the serum just runs completely out.
Lala has her fore hooves up on the counter to balance herself. Her sharper hip bones would make sitting in the wooden kitchen chairs painful. Her extremely long hair is really disheveled now since it hasn't been combed today. Her bright aquamarine eyes shimmer as she looks at you and licks her neon pink lips for a different reason than her food.
"Lala, nu-nouuu-need to control . Can't... mmmilk. Moom-muh-milk but no... uhm... drink! No drunk."
It is hard to talk. It is hard to remember all your human words, but also whenever you make certain sounds your throat and mouth muscles just sort of relax and force them to trail into a lowing sound. So even when you remember the word, you can't always say it correctly.
"Moo."
She was looking at your floppy cock as she dropped to all fours and started to trot over- her hooves clicking on the floor like high heeled shoes.
"Listen?"
"Moo."
"Lala..."
"Mmmmm-Mmmuuuu~" There was a slight tremble in her voice that made your cock twitch and start to slide forward. Her voice is slightly lower now too, again.
She immediately put her head under you and nuzzled your sheath to coax more shaft out and you side-stepped away.
"Lala." You tried to sound more commanding, but your thunderously deep voice only made her pussy quiver.
She turned her rump to you and slapped you gently across the face with her tail, tickling you with the long tassel hairs. She knelt her forelegs to put her butt up toward you. Her neon pink pussy stood out against her paler flesh, and trailed onto her massive udder. So much soft, supple, hot flesh. You feel dizzy, and memories of fucking her return to the front of your mind so vividly you start to thrust your hips a bit into the air. Maybe if you fuck her, she will listen then? A cow should listen to her bull. Her hips give off a hollow pop and jostle abruptly as they enlarge! That is the last straw for you, and you quickly hop up and mount her! You thrust into her so hard she has to scramble and dig her hooves into the cracks between the tiles of the floor to prevent you from scooting her across the kitchen by her pussy! You thrust into her hard, hearing her sigh with every thrust because you are actually knocking air out of her lungs because of how much cock you are stuffing into her! Your balls swing forward with such force that the long scrotum slaps against the back crevice of her behemoth udder, making a loud clapping sound with each hit! Her udder starts to blush a deeper pink where your balls are repeatedly slapping it!
The hottest thing about fucking your cow-half wife like this though? You can feel the weight of all her tits swinging through her body! The subtle way her body shifts to try and counter the weight of her mammaries swinging around and stay balanced, the tug on her skin and muscle as the large globes slosh about- you can feel it through her entire body. You can feel them swinging without actually touching any of them. Her desperate, breathless moos telling you that you were hitting all the right places.
She starts to squirm around under you and you hear more bones popping! Her rib cage is expanding, and her torso getting longer! She grows into your underside and starts to force you up off the floor! Her entire body is growing in size! Her expanding chest is starting to swallow her breasts- but in return her udder starts to swell with such vigor that it audibly gurgles. A shadow of growing fur spreads across her, becoming white where she was formerly peach, but remaining the same orange-brown the spots already are. Your fur is solid black. You grip her sides with your forelimbs as tightly as you can to keep your balance from your aggressive thrusts. You slam her pussy open through the soft inner folds and feel it all contract and grip your dick as it slides back out to ram in again. She has a cow pussy now... so how big is your cock that she still feels tight? Ooohoo... that thought only causes your thrusts to increase in speed. Your own body starts to get slowly longer, and more barrel shaped- though the massive amount of muscles on your upper limbs and back give you a hump-backed appearance even still. The veins in your neck throb rock hard and your entire neck bulges larger and longer! When the bridge of your nose pops loudly, your heart is hit with worry.
Change? N-no can't, I not drink milk, no Lala in... in... oh.
It occurs to you- though you no longer possess the words to put it into coherent conscious thought- that you are in fact exposed to Lala's fluids still. Her pussy. If her milk can transmit the hormone, so can her spit, so can her vulva's natural lube. Even kissing her could cause minor changes at this point, now that your overall dosage is high enough. You rock back and forth from her body below you rapidly changing proportion- an absolute cacophony of shifting bones as she rapidly grows toward a full cow! You look down to see her head deforming- her face pushing out and her human hairs starting to fall out again. Your vision turns blue from blood pressure behind your eyes as your own face starts to shove out! You want to push it back in, to keep it in its old shape but you know you cannot. It just pushes further and further out, your head growing and growing while your mind shrinks and shrinks.
So hard think. My not bull, is... we... good, milk, cum, me give... want... mmm...moo?
More and more of your own muzzle took up your vision. Lala lowed loudly as she orgasmed around your cock. Oooh no, her pussy fluttering around your shaft is rapidly firing you toward orgasm too. Well, no point in thinking about it at this point, really. You are so much bull that there is literally no point in even trying to resist. Resisting won't make you human, it will just make you an incomplete bull. Your eyes are forced to the sides of your head from the expansion of your face.
"Muh! M-m-mou-m-me nu bull m-memmm...mmmu-uh! Mau-uuUUOOOOOO!!" You bellow loudly as you hit climax! Your body becoming fully bovine with a powerful orgasmic shudder!
Your childhood? A pasture, grass... wait, was that..? Probably. Bull, human, bull, human... what was the difference? You cannot remember. Who were you? Who are you? You cannot think of the words for it... what are words? You cannot remember your own name. You know your smell, and you know Lala's smell. That is how you two identify each other now. Neither of you can remember the human words that are supposed to go with that identity. At least you know what she is talking about when she lows at you now. There are no words to translate it too- bovine do not speak with words. They convey emotion from their bellows, and if you listen hard enough- any species can translate that.
You wake up slowly, on the barn floor. Naked, confused... tired. A month has passed- you are roughly 75% human today, but most importantly your brain seems to have woken back up. You remember everything that happened in the last month, of course but... it is hazy. Your instincts were louder than your conscious thoughts, so it was like your body moved entirely on auto pilot, like in a strange dream. You are pretty sure the other cows are either very impressed or emotionally damaged from watching you and Lala fuck in every conceivable position, including many you have no doubt that no bovine has ever contorted itself into before. You were unable to ever stop drinking her milk or having sex, but you slowed over time at least. Between that, and the fact that even her dose is started to thin now is what enabled you to return to a human state. Lala is still 75% cow. You are trying to train her to be more human, to restore her form a bit if you can. You can tell it will still be some time before her actual serum dose burns out and she can actually go human so... maybe you shouldn't even bother? She is a bit human now- feed her some nice human food, give her a bath and let her sleep in the house for a nice break and then just let her go full cow again? Till the serum runs out completely it is an uphill battle with no real end, so you aren't sure it is worth dying on that hill.
When she lost her breasts in the full transformation, their mass was transferred to her udder. She still currently isn't enough human to get her breasts back, so her udder is... immense. The only cows who have come close to her current size had serious medical issues, because that size ain't natural. Even with bovine hips the sides of her udder bulge out around the sides of her hind legs, and the teats stick straight out, bent to the sides because the bottom of her udders rests fully on the ground under her while she is fully standing up! The giant's shackle she wears as a collar actually fits her normally with the full neck of a cow- and is the only reason you were able to lead her back into the house when she was still 100%. You just put a rope through the chain link at the front and lead her by it like a leash.
You watch her watching television- not enough human brain in her to understand any of the things she is watching, but still bemused by it. You unconsciously lick your lips, looking at the gargantuan udder. How much milk do you think that thing contains? Probably enough to overflow the bathtub. You should... drink some. Oh but... more bull. Well.... the effect is diffused anyway, you won't turn as bad, unless you drink a ton. And your cock would grow again if you drank enough. Mmm, and your balls. You can spank that udder from behind as you plunge into her again. Yea... it will wear off completely eventually, it doesn't really matter if you turn bull again for now. It doesn't matter if Lala is human or cow- she is absolutely gorgeous in whatever form she takes. You have no preference- she is always perfect for you.
You kneel down in front of her monstrously huge udder propped up on the couch and start to suck. Lala is surprised- she did not see you coming but then smiles and rests fully back down on the couch while you suckle from her fat, engorged teats. The rush of blood to your penis is immense, because you feel it both getting an erection and starting to grow at the same time. The glans itch with internal blood pressure as they purple from the blood pooling there first. All you can see is a veiny wall of soft, smooth, hot, elastic titty flesh. And all you can think about is how long it's been since she had a period. Lala is pregnant. That udder only gets bigger from here.
