(F tf Bovine, Cow&Bull)

Gwen worked at a library, and honestly spent most of her days just reading random things. Not many people were reading to entertain themselves these days- and if they wanted to learn something they were quicker to turn to the internet than the library. So most of the time she was just standing around bored and could read the books she is surrounded by.

Gwen has long brown hair to the small of her back- though it completely lacks any volume and hangs perfectly straight and her eyes are an army green color. She has perky little jiggly B cups under her shirt with peach toned skin absolutely blanketed with a million brown freckles.

Today she is paging through a giant tome- it had been returned to the library after being gone for quite some time. Apparently it has slipped through their security scanning before; and is supposed to be locked up in the private arcane collection. That is why she is looking through it now though before she moves it to the reserved storage. She cannot fathom why it belongs there. Only advanced spells that could potentially be harmful if put into the wrong hands are kept in the private collection, and thus require clearance to remove. This tome is an all-in-one item conjuring book... and almost a hundred years out of date to boot. How the hell is someone going to cause trouble by summoning a friggen chair?! Uh oh, person summoned a comb incorrectly, now it has too many bristles- better throw the book in secured storage.

Gwen could not for the life of her figure out what in this book could possibly cause anyone harm- unless someone summoned a knife and fork and then stabbed themselves with it, but that wouldn't be the book's fault. Looking over the hundreds and hundreds of different items it can conjure for her though; she did end up taking the book home with her for the night. She could trace some of these runic arrays to use herself. The book attempts to have one of everything- so there is no variety in terms of each item. If you want to conjure a bed, it has a bed, but only one bed; you cannot change the size of the bed, the color, or type- the book has only one.

"Oooh, a bicycle! I could get to work faster!" She turned the tome sideways and put her finger in the way of the falling pages to stop at a random place. "What do we ha- oHO, wow."

The book is almost a hundred years old so Gwen was really not expecting it to have an entry for sex toys. Though, sex is the world's oldest entertainment. It doesn't even say what the toy IS. Like, the book only has one of each item but... the toys men and women use are generally very different, but the tome only has one entry for 'marital aid' so... what is it? For boys or girls?! If it only has one it should at least say what it is, because depending on your gender you could summon a toy that is of no use to you. A fleshlight cannot be used by a woman.

Out of curiosity alone; Gwen decided to cast this conjuring spell. She had to see what this thing even is in the first place. What did they think was a one-toy-fits-all, a hundred years ago? Dildo is probably the most obvious answer- since men can also use it. But if it was a simple dildo- why doesn't the tome say that? It completely omits what the object is outside of a 'marital aid'.

She completed the spell and in a dull flash of light- mana super-condensed into a tiny peach toned bead! Then the bead wobbled and grew! The edges of it glow as more mana is drawn in to feed it, but its form doesn't seem to evolve at all. It remains a flesh toned sphere and simply expands to the size of a marble, then a tennis ball, then a softball, then a honeydew melon and then just plops down onto the table over where it was summoned.

Gwen nudges it, blushing a bit. "It kinda looks like a boob, but... it has no features, no nipple or anything."

*Is that what I look like? Thank you for describing it- I lack eyes of my own.*

"Wh-oh, uh... you can... why... are you sentient?"

He doesn't even have lips to speak from- though it sounds like a normal voice to Gwen, it is actually being projected into her thoughts; there is no actual sound. A smooth, deep voice- sounds like an older man. Why in the hell would a sex toy be able to speak or think at all?!

*The better to do my job, my dear! I exist for your pleasure- whatever that may be.*

"Wait- so you can... shapeshift?"

*Yes.*

Maybe THIS spell is why the tome needed to be locked up. If it can become anything related to a person's sexual fantasy- if they are into torture, this spell could be used to summon a literal weapon. That is why it just looks like a sphere- he hasn't been told what she is into yet, his mass is amorphous by default so that it could potentially turn into anything required of it.

Gwen blushed even deeper. "Er, well... the thing is- I sort of summoned you just to see what the spell did. I... don't actually require your services."

*Oh come now- everyone should have some pleasure whether they need it or not. It is something everyone wants.*

"Well, at some point yea- but not right now. Sorry, I had no idea you'd be able to think. What is your name even?"

*I have only existed for mere seconds- so that is up to you.*

Oh, right. It is a conjuring spell, not a summoning spell. This toy was just made out of thin air- so he was technically just born.

"You have the voice of a refined gentleman, so... how about Vincent? A classy name."

*Then so shall it be.*

She ended up idly talking with him the rest of the night while looking through the tome and summoning a few other nick-nacks for herself. The objects it conjures are made from condensed mana- so when the ambient energy levels dips too low to sustain the form; they vanish back into thin air. The objects are not permanent, so Vincent as well will just vanish eventually. Since he is not actually doing anything after being called into existence, he should last a while, because he is not burning any energy.

Half from feeling bad for him and half because she thought it would be fun- she pocketed him the next day and brought him to work with her. He just looks like a ball- even if someone spots him; they aren't going to know what he is. Today was particularly boring- Gwen had run out of books to read that she knew of as well. Even with Vincent to talk to she was bored out of her mind. She returned the tome she used to summon him to the private collection as instructed, so only those with special permission could withdraw the tome. She still didn't really know why it needed to be there, but whatever.

*You seem pained, my dear?*

"Boooooored. No wonder the rest of the librarians are so absentminded- you have to call to them several times before they snap out of it. Wander the isles like zombies. People don't really use libraries anymore."

*Well you have me. We could... make some fun.*

"Ha! That is true." She paused a moment furrowing her brow. "Wait, you aren't serious, are you? I am at work!"

*So? There are bathrooms you could stow away in. And you said it yourself- no one ever comes here. If no one comes around to be able to see you, then it doesn't really matter what you do, does it?*

"Y-well-no, but I mean yes! But I am not horny! I know you were literally born to fuck, but I have to actually be in the mood. And being bored in a giant library is not a turn on."

First her ears, then her face, then her loins felt warm, then hot, then blushed. Her clit woke up suddenly from its slumber and swelled round and tight- the internal portion fattening her mons and causing her pussy lips to project out and blush!

"Wuh...? W-huh... huh... wh-what, what did you?"

*You said you could not experience pleasure without being turned on; so I turned you on.*

Like a bloody light switch. Gwen has literally never felt like this before! She supposes that means she has never been fully turned on before- given her track record with relationships; that checks out. Vincent also shrank a bit- influencing her body required he dissolve some of his own mass back into mana to influence her with. You know what? Fuck it, why not. This feeling is wild and she decided to go with it. Her outer pussy clenched tightly but her inner passage felt like it yawned open, it felt empty, longing to be filled. She could feel her pussy moisten- making her nervous she would start to dampen her clothing if she did not take care of it quickly!

She headed into the mathematics section- the most god-forsaken wing of the library. The dust on some of these old texts was thicker than the book itself. Rather than go to the bathrooms where people actually also go, she went to an open isle where she knew no one will ever visit. Which also kind of turned her on. She is doing it at work, out in the open. Gwen fell against a shelf, leaning her hips out and tucked a thumb under her panties to slide them down so they do not get wet with the building moisture. She wears a knee-length skirt, so she can simply reach under and remove her panties without pulling anything else off.

Vincent's form abruptly yanked inward, at first surging up into a shaft, then blooming into wide glans before the remaining mass wobbled back down the shaft and formed into a pair of large testicles! Gwen's face was stuck in perpetual blush and her whole head felt hot from the induced arousal and she squat down and slid the head of the penis in gently from behind- so his balls face forward.

Gwen gasped when she felt the shaft clench, the glans tighten and swell a bit larger before the entire toy lifted off the floor to gently thrust in! He can... move?! Vincent can move on his own! He also throbs and pulses like a real cock! But... he feels rubbery when she touches him with her hand. But for some reason when he makes contact with her pussy, he feels like flesh and blood! Even the fake balls lift and swing around in the rubbery scrotum as if there was actual testicles in there- even though the balls and scrotum are just a solid piece of the same material all the way through.

Gwen softly moaned and gasped at his movements, and gently flopped over onto all fours, closing her eyes to enjoy just the feeling. It was so strange- the force of his thrusts certainly felt like someone was fucking her, but then if she looks behind her; there is no one there. Heck, she could put her panties back on and walk around while he is still fucking her because he has no body attached to the dick.

*Do you like that?*

"Mmm."

After a few minutes she told him to go harder, and Vincent started to thrust harder- so his balls not pat her clit when they swing forward with each thrust. Her pussy started to clench harder, drooling lube. He sped up, thrusting a bit harder still, causing her to grunt softly with each thrust and brace herself on the floor to prevent him from knocking her forward onto her face! Her pussy started to clench more frantically, rippling inward like it was trying to drink the cock before her muscles lost control entirely! Her knees wobbled as the tremors of orgasm shuddered through her entire lower body- she shoved herself up in surprise but her legs could not support her so she flopped onto her butt; which only shoved Vincent into her even deeper!

Vincent seen she was pawing at her crotch looking for some part to hold onto, and his testicles expanded to the size of a large potato each- or like, oblong softballs, so she could grab and paw at his balls between her legs! A few seconds into her orgasm she gasped as she felt Vincent erupt cum into her! Powerful jets against the walls of her pussy, filling her with searing hot goo! The fat veins along the shaft ripple as the cock clenches and erupts. Wait... how can he cum? His balls aren't real.

Vincent was trapped- he could not move till Gwen did because she pinned him to the floor with her ass. His cum filled the remainder of her vaginal passage that his actual shaft did not, making her feel very pleasantly full. As she came down from the high the gears in her head started to turn as she looked at his balls, wondering how they grew as well. In order to change his form he would need to use mana... except his entire form IS mana- so changing his shape would cause him to shrink. She realized that her orgasm took energy- quite a bit of energy from her. Energy is the most basic form of all matter, it cannot be created nor destroyed, so all that energy had to go somewhere. Her orgasm super-charged Vincent, he converted it to mana to extend his own life!

Gwen glanced at the clock on the wall, then chewed her lower lip. "I don't suppose you could... do that again? I have a lot of time to kill... heh."

*Anything you desire.*

"Heh, you shouldn't be so gentlemanly... at least when we are doing something like this."

He suddenly sounded irritated. *I do it because I want to. Whether you think it's gentlemanly or not isn't my problem.*

"Mmm, not rude, either."

*You know I need this too! S-stop slow balling and give it to me!* Now he sounded aggressively horny. Yea! That is what she was looking for!

He thrust into her so suddenly and aggressively that she fell over onto her back! Oooh~! Just right! She felt something brush her sides and then touched herself there in mild confusion. Like a being touched by a ghost... what was that? Oh- his balls still face forward, so on her back like this; if he had a body she would be on top of him- what she felt was a short-lived imitation of him grabbing her around her sides and hugging her to his 'body'. He does not have enough mana to pull the illusion off entirely though.

As soon as he started to thrust into her again her entire body felt tingly! Her pussy loosened and the muscle tension dissolved. He reset her arousal, and kept her pussy drooling so she would not start to chafe from having extended sex. Vincent also knew she liked the feeling of being full with his cum, but with her pussy loosening up and him moving again it was going to escape! It felt like he throbbed hard, but another throb came without the shaft relaxing from the last one! Gwen's eyes went wide as her fingers gripped the soft carpet below her. He is growing! His cock is enlarging to push against the inner walls of her vagina... preventing the cum from escaping past it. He remained as tightly clenched in side of her in spite of her pussy loosening up from use! His scrotum grew longer and his balls even larger- becoming almost like a football- in size and proportion, though rounder on the ends obviously.

Very slowly, a small but strong throb at a time his cock continued to grow as he fucked! Deeper into her pussy, pushing on parts of her body she didn't think could be touched while holding her vaginal passage further and further open! The neon pink of her outer pussy wrapped so tightly around the base her clit was squashed in the taut folds. She could see a bit of movement on her lower gut! Vincent grew so large inside of her that she can almost see his dick THROUGH her torso!

His thrusts got staggered and aggressive, leaning into the desperately horny motif. Her moans, grunts , and giggles told him she enjoyed it, so he continued to lean into it.

*This is what was waiting for you all long- if you had just allowed yourself to get horny enough to indulge.*

"Mmm, hmm, hmhm~" She chuckled as she hummed in pleasure.

*You are so beautiful, I cannot help myself!* Gwen cooed as her entire butt was lifted off the floor by his non-existent hips as his thrusting sped up. *You drive me wild- so wild! A feral beast! I can't-*

"Oooh?"

*Can't hold onto my humanity!* He drew so far back that he popped out entirely, letting the cum escape, but then when he thrust back in he lanced her anus!

"Ah! W-wai-ah-ate!"

*C-can't- n-need, NEED!* He was grunting when he thrusts now! Or... sounding like he is grunting, since he doesn't actually have lungs.

Her eyes went wide and her gasps became rapid as well as his cock stretched her and started to grow even bigger! Her anus was not stretched ahead of time-but his shaft was plenty lubricated at least. It also started to change shape. As if her anus were smothering it- it became longer but became a bit narrower, especially toward the tip. The fat edged glans started to lose definition, like it was rubbing off on her insides. His dick slowly losing shape like a popsicle being sucked. The veins on his shaft so fat she could feel them pressed against her inner walls as they throb and squirm around under the skin as they dig deeper and stretch longer!

Gwen gasped in realization at the shape of his testicles and very long scrotum. A BULL!! He leaned so far into the role of losing control to his lust for her that he is literally turning into a non-human phallus! She is getting fucked by a... an animal? Er well, half-animal still at this point. Or... toy, technically. Her mind can't think on the details she is having too much fun, fuck it who cares! Let the bull ride her!

What had been a simple rubber ridge representing the foreskin before he started growing was now shoved back by the cock vastly overgrowing it, and it widened as it drew back becoming a false sheath for the now bestial dong! A new ridge formed as a mid-point and the dick extended so long it became tiered! Her lower body tingled so strangely, he was prodding places that had never been touched! His dick managed to take several turns inside of her, digging so deep into her bowels it felt like he might start fucking her stomach from the bottom up! She felt so, SO full!! It is so thick but extremely, incredibly long! He... is he? A full bull penis?! Like, actual to-scale? That should be way too big for her to take! No wonder he switched holes- if that was still in her pussy he would have obliterated her cervix and ruptured her womb!

Vincent did not say anything more now, even in his teasing role-play. Now he only grunts. His voice deepened, his grunts becoming hollow sounding, loud and deep... the grunts of effort of a rutting bull! Gwen felt her hair move! Something moved her hair from behind, even though there is nothing there? Hot, sudden gusts. Bull's breath! When he grunts it blows her hair forward, even though he doesn't even have a head. Damn, he is good at role-playing. And the fact that fucking her feeds him more mana certainly helps too.

Gwen closes her eyes to imagine what she is feeling. Forelegs straddling her ribs, his head over her right shoulder, chin resting on it, his grunts blowing her hair forward and tickling her right ear. A man reduced to a rutting beast, desperate to be in his cow.

"Hmmmhmhm, moo~ uh-oooh!"

As soon as she mooed jokingly, his balls yanked up his long scrotum bunching all the excess flesh under them and he erupted cum deep inside of her. He was erupting so deep in her that her stomach gurgled! Her pussy clenched open and closed like a hungry maw, her clit flicking forward as she spritzed the carpet with pussy lube in her own second orgasm!

Like an actual cock, he turned now to soft rubber and slipped out from the force of her anus trying to clench closed around him. The false sheath fattened and the shaft itself became a bit wider- recalling its mass to form more of a long peach toned spike; retracting but unable to fully pack itself away because... well, he has no groin to put it in. The scrotum tightened, regressing its length to make it plumper and round just to make it easier to manage.

Gwen looked around a bit embarrassed at making the carpet wet, but also surprised at how LITTLE mess they made. "Wait, didn't you cum? Or... wait, was that an illusion too?"

*There was simulated cum- but like everything I am, it is but condensed mana, so when it is no longer needed it disperses and I recall whatever energy can still be recycled. I would not have a lady clean up my messes for me.*

"Yea but even I felt like I had made more of a mess than I actually did."

*I broke it down into energy and absorbed it. Any fluids of yours that made direct contact with my body were absorbed to dispose of the mess.*

She smirked, shimmying her panties back into place. "Well... you can do it all, can't you?"

*Heh. As long as it is in relation to your pleasure, yes. That is my reason for being.*

She glanced around the corners of the isles to see if anyone was around but as expected- no one. There is only two other librarians in spite of how giant this place is, and she is pretty sure there are no guests currently, so. She could have been anywhere in the building and odds of being found were still slim. She glanced back at Vincent about to pick him up and return to the front desk but just gawked at him and blushed.

"W-well I can't pick you up like that, you have to go back to your sphere form!"

*Eh, I-I can't!*

"What do you mean you can't?! I thought you could turn into anything!"

*For your pleasure! Turning into a sphere would help you maintain your image within society, but it would not benefit your pleasure in any capacity- and thus is outside of my ability.*

Vincent literally cannot do anything if it is not related to pleasuring her- even if he has the power to do it, he mentally cannot perform the action. He can hold a conversation easily enough, which makes it easy to think that he has a full range of thought or emotion, but Vincent can only do that because it helps with the illusion, and her pleasure. He isn't technically a living being, he doesn't have a heart- he cannot die. He is a toy- a very elaborate and very good toy, but still just a toy.

Gwen grumbled and picked him up, wondering what she is going to do with a floppy bull dong till she can smuggle him back home. His form quickly liquefied, running up her arm, spiraling around her shoulder and then hugged her neck!

"W-wuh?!"

*Here, try this form! A gift for my beautiful cow~*

"O-oh!" She dashed back to the counter so she could get her emergency makeup kit and use the mirror inside to look.

He transformed into a pink ribbon choker, with frilled edges, tying a golf-ball sized round golden bell to the front of her neck! Because it technically follows their little sex fantasy, but it's also something a human could wear. The ringing does not become annoying- it rests against her neck so she has to move pretty abruptly to actually ring the bell, or bend over.

Gwen continued to feel echoes of the horniness spell- the spell itself already gone, but her body wasn't sending any opposing signals so a ghost of its effects remained. She... never felt pleasure or arousal like that before. It made her daydream- and that helped pass the time a lot. Gwen did not even plan on using a sex toy, she summoned him just to see what he was. Now she is very glad she did. The tome is locked away now, but she can keep Vincent for a while regardless- absorbing and converting her energy and physical fluids would have given him enough energy to remain manifested for some time, even if there is no ambient mana. It's like a backwards battery- using it extends its life rather than shortening it.

She sighed, resting her chin in her palm, staring blankly at the closed front doors no one was coming in through.

*What is it my dear?*

"Mmm, just daydreaming. All that cow and bull roleplay got me thinking about my boobs. I mean- my titties are cute n all but... I ain't no cow."

*You wish they were larger?*

"Yea. Well... I dunno. I never had big boobs to know, you know? But I have always wondered. Don't want the back pain but... how would they feel? Maybe it would be worth building the back muscle to deal with it? Eh. No use dwelling on-n-n-nnngh! Waaaaaht ah-AH- AH!"

Her breathing immediately became rapid and the bell on her choker softly rang... as her nipples immediately hardened against her shirt! Solid little dark brown cylinders like the eraser on the back of a pencil stood in defiance of the fabric over them! Her breasts are small and pert enough to never actually need to wear a bra, so she doesn't have one! Her areola became bumpy and tightened, then her breasts felt warm, then hot, then tight. The skin pulled so taut that it looked wet because the divots of the tiny pours pulled completely smooth from tension. Her skin blushed slightly and Gwen went to grab them but shivered from how sensitive they are and simply hovered her hands in front of them, not knowing what to do!

Vincent is... making her tits grow?! He can transform OTHER people?! She is really starting to think that his spell is the reason that tome is locked up. If he can transform HER, that means he is effectively a spell that is capable of casting OTHER spells. Something that is incapable of feeling, or rationalizing a situation shouldn't be allowed to cast spells!

Her breasts became abnormally round, filling, stretching. She ended up tugging the shift off them because while they stretch the nerves are too sensitive and raw, even the loose fabric was like an electrical current through her! C cups and then D cups. Her nerves settled, the skin relaxed and her breasts slumped down a bit- returning to a natural tear-drop shape. Her nipples remained erect, just from the pleasure the growth induced.

*Sorry- that is all the power I have currently, I hope this size is adequate?*

"H-hooooly shit. You can transform ME?"

*Anything for your pleasure, my dear.*

"Oooh but I don't know...well. I guess... it's fine."

*Well, certainly, it is your body, you should be able to do what you want with it.*

She gingerly touched them, and when Gwen felt they were not too tender she quickly dug her fingers in through the fabric to knead the fattened flesh.

"Oooh, wooow. I don't suppose you can alter the flow of time so I can go home already?"

*Hah, no. Maybe I just need more energy?*

Gwen could barely keep her hands off herself. She lifted herself up onto her toes and then dropped her heels back down to feel her new boobs bounce in her top! She poked her erect nipples through her top and rolled them in circles like they were joysticks.

When she got home finally after work she kept going back and forth with herself over whether she should go bigger. Vincent only stopped because he ran out of extra power- he could not make her any bigger without diminishing himself. But that is a very easy fix. She rides his meat stick again, she charges his batteries- he can then make her bigger. Basically the way to more pleasure was... more pleasure. She had a full conversation with herself going back and forth on the idea without Vincent even getting in a word as she paced her apartment. Vincent just remained hugging her throat, ringing softly when she bounces her boobs around.

"You can undo the change, right?"

*Ye-*

"Like, actually. I know you have the capacity to do it, but CAN you actually do it."

*If they are too heavy for your back to handle that will cause pain, the exact opposite of everything I stand for, so yes. In the event they are too much, I should be able to undo it. If you actively do not like something, it is my job to dispose of it, whether my own magic is the cause or not.*

And so of course Gwen caved and decided to ride the bull again that very night, this time attempting to take him in her pussy. Vincent firmed up but remained in his thick, squart form as the furthest retracted he could be while still holding the shape of a bull's pride. It worked as a warm up, but he was still too much for her pussy, and could not thrust in fully without hurting her, so once her blushing nethers donated a generous portion of lube, he swapped holes, fully extended and once again impaled half her entire torso on his throbbing pillar of synth-meat.

Rather than grow her suddenly and white out her nervous system with too much input- Vincent grew her in tiny bursts as they fucked in her bed. Her D cups would tighten, then blush and stretch a tiny bit bigger, then settle down. Before the feeling of the first starts to fade, another pulse happens, extending the pleasure of growth. Nerves being stretched, branching and extending but never becoming raw or irritated because the meat around them fattens along with their own growth. Of course Gwen had no way of knowing that Vincent was also increasing the size and number of alveoli deep inside of her breasts as well... which is where milk is manufactured. He isn't just fattening her up- he is increasing the entire organs.

When he performed his illusory ejaculation magic trick again; Gwen rolled her head back with a half-sigh half-yelp of pleasure. Since she would pop off after, he surged the growth a bit higher at the end. This pulse concentrated itself- rather than a gentle, incessant pleasure across her entire chest, it concentrated into the fronts of her breasts only! Her nipples tingling with increased pleasure, becoming almost irritatingly erect. Her bumpy dark areola started to swell forward! They became enormously puffy, forming half-spheres of their own, and then her nipples increased in overall size a bit to remained matched. Gwen only considered the aesthetics of the change in the aftermath, but the reason her areola projected is that Vincent caused her to develop milk reservoirs in the nipples and areola- something a human does not have, but a cow does.

"S-shoot..."

*Something amiss?*

"Aha... ah. N-not exactly just... this is WAY more than I intended."

She wanted bigger to feel the growth again mostly, to feel the weight grow, tug at her flesh. Gwen envisioned a modest increase to DDs- which is about the same as an F cup. She does not know what bra size she is now, but from her first-person perspective of her bosom; when she looks down all she can see is fat flesh. There is a four foot gap in her vision when she looks down; where she cannot see the floor past her own tits. Each breast looks the size of a large water melon, and the weight of their perfect tear-drop form puts their rounded bottoms very slightly lower than her final set of ribs- so they touch her midriff lightly even while fully standing. Put these in a shirt and they are going to sit even higher and rounder, blocking even more of her vision.

On the other hand... her back somehow does not hurt from this... and she does like them. She cannot keep these forever! Gwen knows that for sure- absolutely not. But for a while? Eeeh, why not? She doesn't have any friends that she is in close contact with really, the other people at the library only occasionally interact with her, and the library gets abysmally few actual visitors. She spends all her free time indoors so there is very few people who see her normally to even be able to spot the difference in the first place. The weight is a constant reminder that they are there, fat, bloated tits wobbling and undulating obscenely from her body, uncontrollable, and barely containable. Lewd, perverted, kinky. Gwen only has a few pairs of bras in the first place that she rarely ever bothers to use- she certainly has nothing to contain these, so she is forced to wear a baggy shirt to work the next day, knowing full well her enlarged nipples are visible through the fabric even when they are soft.

She has to tend to a few visitors the next day- it is the weekend so at least a few people stop by on their days off to grab a book. For most of them; Gwen pretended to be sorting some books under the counter so she had an excuse to be bent over- so her tits were under the counter. She also misjudged the space they take up several times and accidentally knocked over a few books while trying to do something else and sweeping the countertop with her tit flesh! Stuffed into a top to actually contain them- they pull the fabric taut and are lifted into spheres, causing them to project further out off of her than they already were. If she extends her arms forwards- the fronts of her breasts are past her elbows, making her breasts wider around than half the length of her arms! Having these heavy, inconvenient things jiggling around wildly would be frustrating as hell- but knowing she had the control and could grow or shrink them whenever she needs instead made it sexy.

Gwen handed the library card back to an old man. "No, sorry Mr. Lockley, nothing moo."

Gwen froze and blushed, but the old man just nodded and shuffled off slowly- his hearing wasn't what it used to be so he did not notice she said moo instead of new.

Vincent's bell rang softly. *Ooh, good cow!*

"D-don't say that! I didn't mean to say that!!"

*Oh? Heh, Freudian slip? I do love it when you moo.*

She groaned, turning to lean her back against the counter, putting a hand on her sides and scrunching her face up in irritation.

*Stomach problems?*

"Ugh, just... that time of the month. The time when you kinda wish you'd have been born a man instead."

*I could take care of that for you, my dear.*

Gwen was silent for several moments before she glanced down at her bell. "How... the fuck... would you fix period cramps?"

*I am designed with pleasure in mind, anything relevant falls into the realm of my expertise. I cannot directly relieve your cramps, no, but I can make you male.*

"Wh- NO! No one would know who I am, I can't work here if no one knows it's me!"

*I can leave the rest as it already is. No one is going to know what your genitals look like to know the difference.*

Just her genitals? She can't get period cramps if she has no pussy. She could always reverse it later, she supposes, so... what is the harm? Just wait out a week with a tiny male package tucked under her panties. So Gwen slipped into the bathroom, put the seat down and stood over the toilet in a locked stall to shimmy her skirt down to her lower thighs and then timidly took her bell off and placed it on her suspended panties as Vincent turned to his flaccid bull phallus form standing on her panties below her pussy, nudging her blushing lips.

Gwen's skin turned to goosebumps from an odd sensation of tingles deep inside of herself- too deep to really identify the exact location. The cramps loosened greatly though from the pulse. Then another wave, and the cramps were gone. Another and she felt a bit horny. Another pulse and her clit hardened and her mons fattened. Vincent narrowed- standing slightly more erect as his form stood up into her gently. Her pussy clenched as the rings of muscle that line the inner vaginal passage actually shrank! As if being fed on displaced mass- her clit became so hard it actually ached! The skin tight as a drum across it. Another pulse, her pussy shrinks, her clit starts to push out of its hood! It turns purple with blood pressure!

Vincent just undulated his length to penetrate her over and over with only the very tip of his phallic body as her pussy was diminishing in size quite rapidly, and he did not properly fit into it even when it was full size. In her ovaries her eggs split- trailing nubs at the break-off point that then grew into tails as they learned how to swim, transforming into four times the number of sperm! Her ovaries swelled with the increased activity, growing massive and getting shoved downward from lack of room- partially collapsing the vaginal passage as they descent, as if closing her from the inside out like a ziplock bag!

Gwen's lips were sealed so tightly they lost color, trying to muffle herself as much as possible, making whimpering cries of pleasure as her legs trembled. Her entire groin was alive with a strange electrical feeling pleasure! A bit of cramping, strange movements, gentle tugging, and an electric tug of pleasure- so many feelings in such a limited space. Her clit grew longer, vibrating from the sensations and its rigidity. It looked like a neon pink thorn, then a cone. Her labia and mons started to look repressed as the internal portion of the clit drew itself out, shoving the mass into the exposed portion. Muscle ribs that formerly lined the vaginal passage now re-appeared in the clit to help it stand, creating the structure of a phallic shaft instead. As it stretched out though; the glans lost definition against the shaft, so it retains its tapered structure regardless of how large it gets. Oh... wait, he isn't giving her a HUMAN penis! He is giving her a tiny, under-developed bull penis!

One ball popped out and then the other- her ovaries now mutated into testicles and rejected from inside of her collapsing pelvic floor into a new scrotum- which in turn is made from what had formerly been her labia, knit together. When her testicles popped out the left ball came first- since they could not both fit out at the same time. The sharp, short-lived ache of it popping out of the tiny opening caused her left leg to collapse, so she slammed into the left side of the stall, then collapsed onto the closed lid of the toilet when the other joined it.

Gwen looked at her transformed genitals, breathing heavily. Balls barely larger than a grape each and a penis a bit thicker than the base of her thumb, but only the length of her pinky finger, shaped like a neon pink cone.

*And there you have it- your manhood, madam. Not much- but we can make improvements as you desire them.*

"J-just a dick is fine."

*But you have one now- you might as well use it, right? Surely you must have wondered at what point what it is like to have one?*

"Well yea, but. But..."

Since the shaft is so tiny she just placed the end of her index on one side and her middle finger on the other and masturbated the little thing to see what it felt like. She was very gentle at first thinking it would be over-sensitive based on how her clit felt before, but a penis is made to take more of a beating than that- you can be considerably rougher with it without harming it. Her clitoral hood fused around the base to form a sort-of sheath, but because it's so tiny the hood looks like nothing more than two plump folds of skin wrapped around the base.

Vincent lifted on his own, hovering for a moment before drifting forward to press his giant balls into her tiny little grapes, cradling them from below in the crook of his own scrotum. The fat, soft bull shaft grinding softly against her own tiny member.

*You will want larger testicles first and foremost, right? Longer, larger, more explosive orgasms.*

Her balls suddenly felt very full! The pressure felt like it was pushing on the base of her cock, trying to erupt out already, but then an odd pleasure backfired into her balls themselves and the skin of the scrotum pulled shiny smooth and stretched bigger! Her balls let out a quiet gurgling sound as they expanded rapidly!

"W-wai-ah. Wuh... oh-ok-k-kay."

Her balls did little hops as they grew- in the taut scrotum it looked more like they were bouncing off her pelvis. One and then the other, each undulation expanding them a little bit like they were trying to race one another. Gwen bows forward and her middle finger now grips her shaft as she holds in another squeal of pleasure as the shaft stretches longer! Three inches now. Three inches erect- that is still minuscule, no problem hiding that, right? Her balls started to approach the size of chicken eggs. Resting on Vincent's balls- his clench and tug them forward by the scrotum resting between them, then her own balls tug it back toward her as they swell a little bit bigger and sit a bit heavier. A gentle but insistent buzz of pleasure from her newly created prostate sends a slow and steady stream of pre up her tiny shaft. The pleasure causes it to clench, the clenching causes the pre to spurt, then get cut off to build into the next spurt.

Four fingers on the shaft, then five- a new fingertip needed to tend to each inch of added cock! Five inches erect, just slightly below average. Its fine- she wears a skirt, you aren't going to see anything. Balls larger than chicken eggs now, swelling past human testicles and slowly attempting to match the bull testicles they currently rest on. Gwen opened her hand an encompassed Vincent's shaft, pressing the two together to frot. The pre running down just her shaft was enough to share. The pleasure spike caused a surge in growth- it clenched and held for a moment. The veins darken and project further out of the shaft, bloating with increased blood flow, then the shaft itself tingles and vibrates as it streeeeetches bigger, longer, heavier! Six inches, six and a half! The clench lets up and she resumes masturbating both dicks at once, her grip now very wide in order to hold both. Seven inches. Balls the size of large chicken eggs, then tennis balls! Eight inches of shaft, fat veins now spiral around the base like the roots of a mighty tree.

She let out an unintentionally beastly sounding grunt and thrust her hips forward a bit, pushing the base of her shaft into his. Their two cocks together are too wide now- she cannot encompass both. She grabbed the base of his with one hand and held the middle back with the other and just thrust her hips forward and up to rub the cocks together without gripping them. Balls the size of an oblong baseball now. The sheath bulks up, becoming a bit thicker and several more folds of skin engulf the base in a warm nest of peach toned skin to cradle the neon pillar. The taint now between anus and scrotum swells wider! Her balls now the size of softballs! The veins, urethra, and shaft now take turns throbbing- so some aspect is always clenching and growing! Eight inches, nine inches. Shit, need to stop! But need to CUM first! It has a sheath, it can pack itself away better than a human dick could! Ten inch dick! She has a skirt- the loose cloth will hide it!

Balls the size of ostrich eggs, or a big navel orange squashed to be oblong. Scrotum now loosening, extra folds of skin- becoming longer to give the giant balls space to churn. Ten and a half, fuck. Stop! Tell him to stop you dummy! Just... just need m-more! Gwen's face was beat red, her cheeks practically glowing, her thrusting frantic and aggressive. She is grunting like a beast with effort, trying to get off before telling him to stop and procrastinated her way to a full eleven inch long bull dick. Her ears were so hot already she did not notice at all when her ears became longer and elven shaped.

One hand pushing his shaft forward, her hips thrusting her drooling dick into it so their throbbing veins can pulse and squirm into one another- her other hand now stuffed under her shirt and squashing in her breast with her fat nipple pinched between ring and middle finger as she rolls it around aggressively.

"Aaaah.... hah, hah mmmMMMMMM!! MUH- M-m-m-moOOOO!" She was surprised by how loud and low her moo came out! She just meant it as a cute sexy finishing note but it erupted almost like an actual cow lowing! She hopes no one heard that!!

Her urethra stretched massively off the underside of her shaft, and the entire cock vibrated- trying to buck wildly but so rigid it can only vibrate. It was so tight she could feel the pillar of hot white goo erupt all the way up and out of her, a second-long stream before it clenched for a fraction of a second and released yet another streamer, then another, then another. She has never been male before- so her load is the equivalent of 26 years of building up in abstinence. One after another, making her heart flutter even faster now with a mix of worry of the colossal mess she is making on the floor in front of the toilet.

By the time it stopped and she gathered herself enough to actually look- there was no mess at all. Each strand wobbled in the air, becoming more globular as it falls and then started to glow an electric blue before dissolving into the air and vanishing before it actually hits the floor. Vincent converted it into pure mana to absorb and dispose of any messes before they are even made. Converting dense physical mass like that to mana generated a LOT of power too, which means even if he was exposed to a void of ambient mana- he would still exist for at least a year from this load alone without being dispelled. Of course- he did not do it to extend his own life; self-preservation isn't one of his abilities, it is just a side effect.

Gwen's worry at the sight of her giant masculinity helped speed up its regression. The blood left the shaft, causing it to flop over quickly, resting between her thighs and then the blood saturating the spongier material of its body started to drain slowly, regressing its size. A long tapered pillar, then a chubby spike, a wide rounded cone, and finally it sunk into her sheath entirely. The sheath became very fat as a result, but considering how massive her dick is- it hides itself away quite efficiently.

Her testicles are what will be more challenging to hide. Each testicle is too big to hold in a single hand- she can only encompass half a ball in either hand, so her panties sure as fuck can't handle them. She tried to pull her panties up over them but they are not nearly wide enough- either ball attempts to pop out the leg openings, stretching the scrotum between them. No, that won't work, its too tight. She will hurt her nuts every time she moves around too much. Gwen grumbled, pulling her panties off entirely. She will have to go without underwear. Her skirts are almost all knee-length so you won't be able to see these wrecking balls swinging around under her. At least not at a normal angle. The scrotum is long- so they hang basically to her knees too. If someone got a low-angle of her, they would be able to see.

Vincent returned to his bell and ribbon form for her to wear him and she returned to her post. One of the other librarians found her and was stun-locked that afternoon. They could not see her newest additions but they did gawk in bewilderment at the size of her giant tits! Gwen blushed and managed to stutter out an excuse that this is her real size, and she had been using an enchantment to seem much smaller before- but then lost her copy of the spell, forcing her to let her real size out. Vincent rang softly after that and called her a good cow again for her quick thinking. It doesn't matter how obscenely huge she is- if they think that is her natural size they are not going to chastise her for it, because she cannot help how she was born.

After work she walked home slowly, grunting a bit. She did not notice it as much because it had been a gradual decline, but when she started moving Gwen noticed how stiff her spine is. Her lower back was starting to ache now- and she has only had these for a single day, imagine if this really was her natural size? She would fold in half. She let out a sigh of relief when she finally returned to her home, tossing her keys to the counter and flopping immediately into a kitchen chair, not even going as far as the living room. Gwen just needed to get this weight off. When she sits into the chair the bottom of her boobs bounce off the surface of the table, going into a rubbery wobbling fit. She shimmies her top back and forth and gets them out, watching them flop against the table and squash outwards a bit now that the cloth isn't gathering them up. On their own they are heavy and wobbly- imprisoned in cloth they become jiggly and bouncy with the added elasticity of the material.

"Ah!" She pulls her hips back, feeling a growing erection on the cloth of her skirt lifting it up- she is being turned on by her own boobs!

*Need another romp to settle down after a long day? Now that you have male parts- it will also help you get to sleep quickly.*

"Noooo thanks. My back is killing me. Just the rest part for me."

*Oh dear, I am sorry I did not notice sooner- I will correct my mistake immediately.*

"W-what? What do y-AH!" She shivered, freezing and lurching forward, placing her hands on the edge of the table and bending forward so her breasts gather closer and press rounder under the partial weight of her upper body.

The silky cloth ribbon tightens a bit and the bell starts to ring on its own! Her ears twitch at the sound and the cartilage thins, spreading her ears wider, larger. She gets goosebumps again, in spite of being quite warm. The sound is making her whole body tingle!

"Wahaaat are yoUU... m-moo~?"

She pushed her hips even further back, this time shoving the chair further out along with it! The muscles swelled in her lower back, and then caudal vertebrae started to form as calcium surged out from her existing spine! The bones of her back popped rather loudly in rapid-fire, forced apart by the sudden expansion of the muscle around them, then the bones expanded, allowing the connective cartilage to re-set, making a dull click as they connect again. Her entire spine is... growing?! Her abs tightened and became faintly visible as well! Her pelvis became wider and with some alarmingly loud and hollow pops it changed shape slightly as well- her hip bones now look quite sharp... almost like a cow.

A more distressingly severe change however is the skin being nudged out from over her butt longer and longer! A nub, a little cone, a long noddle of flesh! It flicked on its own as if to try and shove the waist of her skirt a bit lower to give itself room. It was almost fully formed before Gwen froze and bristled at the prickly sensation as the end of the tail erupted into utterly flat hair matching her own. A cows tail!!

"N-no! Vincent!!"

*What? What is wrong?*

"I have a tail!! The cow stuff is just... for us." She blushed even though they are obviously alone. "For the bedroom."

*Sorry- but I could not give you the muscle structure of a bovine without influencing you in such a way.*

"The what?!" Gwen stood up, immediately noticing it was no longer hard to heave her giant bosom. He altered her back muscles and hips to be more bovine. With superhuman musculature, she can swing those tits around all day without a problem. "Oh. Well... damn."

She wanted to be mad at giving her a feature of an actual cow, but extra strength and being able to keep her big wobbly sweater puppies is nice. But it's unfortunately a side effect. She has the lower back structure of a cow- a cow has a tail off its lower back. If she wants to keep her strength she also needs to keep the tail. He could not just increase her muscles on its own- he did it through cow attributes because that links it to their kinky roleplay, and puts it into the realm of things he is able to do. He is a sex toy, not a doctor.

"Hrmmm, you still shouldn't do things without me asking!!"

*I am s-sorry master. I thought it was what you were asking.*

His voice suddenly raised several pitches, making Gwen cock her eyebrows. "Why... do you sound like that?"

*Because I have been bad, and need to be punished by master, moo~*

Gwen was a bit stunned and weirded out, but her cock still twitched in response to the now almost disgustingly girly voice coming from the toy.

Gwen took the ribbon off and held it up to her face. "What would I even do to you to punish you in the first place? You don't have any actual emotions..."

The clapper in the bell expanded to fill the hollow of the bell, and the ribbon collapsed back into it to expand its form overall. *Put me... put me under you, where I belong~! Show me who is the bull of this herd, moo.* He, er... she? Started to wobble and jiggle a bit as she expanded into a bigger and heavier sphere! *P-pound me, with your big hard cock! Destroy my pretty little hole. Spank me! Spank me with your heavy balls, moo~!*

Gwen started to lower her because Vincent was getting too large and heavy to hold up! Bigger than her enlarged breasts! The size of a medium pumpkin! A soft divot all the way around her vertically, and then an even softer divot across only the bottom, horizontally. Tension in the otherwise soft, wobbly material fired down and concentrated into four points, erupting almost immediately into thumb- sized teats! Gwen's cock went rock hard so fast it flicked her skirt up and off itself! She is holding... a cow udder!! Vincent hummed in aroused pleasure in her now girly tones as material built up at the very top of the udder, forming a plump ridge, then a projected leaf shape- pointed on either end. It popped open in the middle with a wet *smeck* sound, revealing the moist looking neon pink interior of a bovine vulva!!!

Gwen looked at it dazed for a moment, her cock twitching below. She had to hold Vincent in both hands because she is too heavy in this form. She pressed in with her thumbs and tugged either way, causing the lips of the cow vulva to part, letting her see inside. Her nostrils flared. Did... she SMELL like a cow? A pussy? She bent her head down to smell deeper. It is both subtle and strong at the same time. An illusion. There is no smell at all- but she is being made to imagine a smell so vividly that it is overlapping her actual senses, tricking her into thinking its present. There is also no actual moisture- her insides are just so slick that they look wet. The weight pulled her arms down, her erection pulled her cock up. The two were being drawn together. She turned Vincent around to 'examine' the big floppy teats, but that also turned the vaginal opening to her cock, so when she slowly lowered the udder, she slid inside.

The spike in pleasure of the soft opening clenching in arousal on her shaft caused Gwen to thrust on reflex! The sudden burst of pleasure then caused her to draw back from the intensity, but that created pleasure too, making her thrust in even further. She was fucking on reflex alone! Can Vincent even take her? The udder is large but its round, not LONG like the dick. More and more slid in, surprising her with the depth of the udders. The opening of the vulva is to one side while the end of the passage is on the opposite side, so her cock goes in, bends gradually toward the front of the udders, the very soft material bends outward to accommodate, and then the cock travels forward to the actual end of the passage, fitting perfectly!

Gwen started to grunt again, her nostrils enlarging a bit now, her ears flicked and became more leaf-shaped, enlarging again. She both thrust into the udder as well as slam the udder itself back against her crotch. The super soft material squished in and bounced back into its proper shape almost immediately, causing the material to jiggle wildly and the teats to flop erratically! When she is fully penetrating it- it looks like the udders are hers! It sits against her crotch as if it were her own. Gwen flops down to the kitchen floor and gets onto her back to get a proper view of it while she fucks the udders- because her actual boobs block the view otherwise. On her back her breasts slosh to the sides of her chest and sit with her on the floor, letting her look down her own body and the rubbery, wobbling udders.

*M-MOO! So big!* Gwen just grunts in reply, exerting too much effort into pounding this tight cow. *So m-mmMMO! Your tits are even better than moo-ine! You are m-mooore cow AND bull than I could ever be, moo! Show moo what a real bull is! Destroy moo with your obscene size! F-fill moo with your calves! Make moo fat and MOO-ILKY!!*

Fat veins branch from the base of her sheath and she can only grunt in effort like a rutting bull. Cock so tight it aches! Turning purple from internal pressure! The softness of the pussy is such a contrast, such a relief, she needs it, needs MORE of it. The udders wobble a bit on their own, bloating up a bit- growing!! Gwen's cock stretches to twelve inches long- the udders must grow to keep up! The teats on the udders now swelling as well, looking rounder and plumper as if full of milk. Her body started to curl, lifting off the floor a bit from pleasure. She slammed the udders into her crotch and held them there hard, now making extremely rapid micro-thrusts into them. She squeezed hard on them to feel them swelling fatter- bloating her grip wider with the force of their fattening growth!!

*Moo, milk moo, m-milk m-m-MOO!*

Thirteen inches of cock, fourteen, the veins now violet against the neon pink of the shaft, squirming like snakes below the loose surface flesh as the pussy milks it back and forth! The udders swell bigger and rounder- teats as thick as a shot glass and as long as her fingers and palm together! There are finger-thick veins now visible toward the base of the udder converging on the pussy- they pulse a half second after Gwen's own veins throb.

*MOOOOO, make me a fat, fat cow!! Milky fat moo mama moo!!*

"F-fuck, why are youuUUh s-so.... muh! So... much need- muh, n-need muhr, mumooAAAAHRR!" She bellowed loudly, and at a much lower pitch than she should have been able to!

From her crotch firing up through her entire body it felt like every muscle she had clenched in a wave, and swelled at least a bit larger! Fifteen inches of dick- far longer than any normal bull!! Almost as thick as her shoulder at its base! Her balls gurgled and swelled massively as her load both grew tremendously and erupted at the same time- swelling the testicles to the size of a football each as they lifted to her crotch and juiced themselves against her pelvis!! Her size obscenely monstrous even compared to the actual animal!

Gwen absolutely exploded cum into the udders, and the udders immediately erupted- their teats flicking erect and exploding streams of white into the air with so much pressure it nearly created a mist. But its not milk at all. The udders are lactating the cum Gwen is exploding into them! When it sprays high into the air, it starts to glow blue, and it dissolves as it falls back down, creating a bit of a light show of glittering blue before vanishing to prevent any messes!

Gwen did not even remember going to sleep, she just woke up at the first signs of sunlight appearing on the horizon without having to use her alarm. She sat up abruptly in confusion, then seen the absolutely giant testicles resting between her legs and sheath fat enough to comfortably fit her entire fist inside of. Tasseled tail of a bovine nervously flopping up and down beside her left leg, partially pinned under her butt. Oh boy. That was a wild ride, but now look at the consequences.

She bent over and nudged the giant udder sitting on her night table. The udder is so large in comparison it was slightly drooping off BOTH sides of the table at the same time. "Uuuh, Vincent? You awake yet? I know its early."

*Oh gosh, y-you want me so early~? You don't have to ask, just take me~*

She slapped the cleft of the udder. "No- bad Vincent."

The udder imploded suddenly, forming a round shell, then compressing into a clacker for it, the rest erupted into a pink ribbon to retake his choker form, and also revert his voice and demeanor back to a refined older man. *Sorry ma'am. But yes, I am awake, no need to worry on my behalf. I am not technically alive- I do not sleep in the first place.*

"Can you reverse like... aaaalll of the changes for now?"

*If you allow me to, yes...* He said it was a bit of nervousness, knowing she would not like that answer, but unable to give a different one.

"What do you mean allow you to?!"

*I can't do anything if you do not want me to, and... you do not currently want me to roll back any changes.*

"Yes I do! My ball sack is so long a midget could use it to play jump-rope! If I pop a boner at work I will be knocking books off the TOP shelf with it."

*B-b-but your reasoning- it is all for the sake of maintaining your appearance around others and conforming to the way other things require you to be. None of the reasons are for your own sake! You want to do it because of what others think- not because of what YOU think. You have to actually want the change yourself, for yourself.*

Gwen groaned. That isn't a good basis of reasoning. By that logic half the people out there would probably transform themselves into an immobile blob of sexual organs. If you base a power only on what is pleasurably you'll eventually end up with a form that simply doesn't work; because life involves things that are not pleasurable, it's sort of a requirement. But there is no use arguing with Vincent, it is not as though he can change how he works.

She doesn't have many really long skirts but she had no choice but to dust off the ones she does- because her balls now hang lower than her knees and are big enough that a good swing could bat the skirt away enough to see up it. She also needs to hide her tail in the back, under the skirt. A cow's tail isn't exactly dexterous, she cannot manipulate it fully the entire length- she can swing it in whatever direction she wants and curl it up if she tenses the muscles but that is about it, so she cannot make the tail hide itself.

Barely anyone came to the library though, and even among the people who did- barely anyone looked at her. They just plop the books down and are too busy looking at or thinking about the books or getting back home with them, that they don't actually pay any attention at all to Gwen. She could come to work wearing a clown outfit and there is a 80% chance no one will even say anything. So, the day was surprisingly average. There were a few times she spaced out- bored again, and daydreamed she was a cow in the fields or a strong bull ruling over a herd of his own- then briefly snaps out of her trance to notice Vincent softly ringing. The bell ringing was sidetracking her thoughts... though, it did help pass the time, so, whatever. She is already just standing around like a cow- except instead of a warm sunny field with friendly company she is in a stuffy library.

She managed to control herself and Vincent's over-eager encouraging so she did not have sex at work, but capped off each return home with a romp. As fun as being the bull is- she always feels a bit weird afterwards; it isn't a side of herself she is familiar with, so she always alternates. If she fucks the slutty udder Vincent one night, the next night the ravenously horny bull Vincent rides her. When bull Vincent slams into her, her immense dick flops around only at half-erection, fully extended but not particularly hard, because the dick in her butt is so enormous it partially blocks the blood flow to her own cock. She also loves the feeling of her heavy tits getting heaved around by the power of his thrusts. Feeling her fat bosom swinging around under her as she braces herself on all fours against the strength of the bull's thrusts, it does make her wonder... what it would feel like to lactate.

The days went by and everything seemed to be going smoothly- finding a rhythm with all this so she does not go overboard, while learning to work with her new figure. Between her daydreaming and waiting to get home and let Vincent fuck or be fucked; she failed to notice more minor changes happening to her each time they romp. Even Vincent was unaware- he was not consciously doing anything. He is getting more power than he would ever reasonably need, and because there is already an active bovine spell in Gwen; any overcharged mana seething into her ends up getting shapen into more bovine traits without anyone's direct input.

At first it almost looked like a bruise and Vincent said nothing- it was behind her so Gwen herself did not notice. Did he bang her so hard he bruised her butt cheeks? No, it continued to darken to chocolate brown... a cow's splotch. It is a circle, but it does not LOOK like a circle because its directly over her anus, so the cleft of her butt cheek makes it look like it dips further down in the middle bottom and indents at the top, allowing it to rise higher on her butt cheeks making it look like it starts before her tail, even though the base of the tail itself is not in the spot. Basically- it looks like a perfect heart-shape over her butt.

She is growing overall as well. Little by little, her outfits are a big snug, then tight. She moves too much and her nipples immediately go erect from rubbing into the fabric, then become very obvious to anyone looking at her because their shape is perfectly pressed into the fabric. Now she was really limited to which outfits she could wear because only a few even fit her at all anymore. Since no underwear works- Gwen really has to be careful if she starts to get an erection at work, because her dicks more than big enough to simply lift her skirt up out of the way and jut out in front of her like a third leg. Bubbles of bone over her temples, but still very subtle under her bangs. Her ears leaf shaped now, but she tucks them back and hides them among her hair so people do not take notice- though they are enlarging a tiny bit here and there. The left ear also has a chocolate brown spot that covers most of its length.

One day at work was particularly hard because one of the other librarians was trying to get something off a shelf an violently sneezed, causing her to shove forward hard on the ladder without meaning to and knocked an entire bookshelf onto its side, spilling at least a hundred books onto the floor! Gwen ended up having to help her clean up the mess. Only now when she is crouching down to pick up books does she notice the nails on her toes are enlarged- grey and very thick... turning into hoof segments, but not far enough to not still be considered nails. She wanted to question Vincent on them but obviously couldn't while right beside the other librarian, and then her aching bones made her forget by the time she got home that night.

"Uuugh, that was brutal. I mean the books are not heavy, but there is so many of them and you have to fully bend over to pick each one up over and over- I am not really built for physical labor, thanks to YOU Vincent."

*I could-*

"DON'T." She staggered her way to bed, pulling off and dropping clothes as she went till Gwen arrived at her bed stark naked and flopped face-first into the pillow. "I don't want to moo-oove. Where is my service bull~ just fuck me laying down, I ain't using a single muscle more today." Her voice was muffled by the pillow.

Vincent unwrapped from her neck and rang once before transforming to his bull phallus form. She chuckled and hummed at the feeling of its giant heavy balls sliding over her butt cheeks, resting his hot sheath in the cleft a moment while the cock slides out. She knew they were not actually there- but she could feel the hooves of a bull compressing the bed down heavily at four different points around her from their weight. Her bed is being influenced by the weight of a creature that doesn't actually exist. She could feel the heat and fur from his underbelly brush her back, the hot breath as he snorts behind her ears and ruffles her hair up, even though if she turned to look at him she knows she would see nothing there. A phantasmal bovine with a very real cock.

She reaches up and hooks her fingers in front of his hot damp nose, and loosely hooks her fingers in his nose ring! She can see her skin depressing as if a ring were pressed into their underside, but there is no ring there. Her arm is completely limp- dangling by her fingers in a non-existant ring! She smiled weakly and tugged him forward- leading the bull by the nose and he started thrusting on her command. But a bull does not take creative criticism, it fucks how it wants to fuck, so once he gets going, he is going to go as hard and fast as he wants, ignoring anything she says. At least; that is how the illusion goes. Vincent has a connection to her and knows what she wants already- allowing him to ignore what she tells him while still obeying what she desires.

Vincent thrust so powerfully into her limp body he folded her in half, making her half-moan while laughing out loud! He lifted her entire lower body on the rigidity of his cock alone while her face remained fully rested in the pillow and her right hand dangling loosely by his nose. His balls swung into hers making a faint clapping sound with every forward thrust, her own dick slowly extending lazily, flopping around wildly under her since it cannot go fully hard with his cock dominating it. Her tits are partially pinned under her, but the tops flat against the bed because of her angle- so her nipples are pointing down the bed. His cock is so long there is a audible *shulk* sound for a full second as he bottoms out, then a wet slicking sound as he draws back for another full second.

*So good. Good cow. No one else in the herd is good enough. Only you, you are my only cow~*

"Mmm-moo~."

*I will fill you, make you milky and large!*

"Hehehmm~moo." Her eyes opened wide when she felt a hot tingling enter her breasts, "W-wait, n-nnnngh.... fuck it."

Gwen didn't think he meant he was literally going to fill her with milk. But it is too hot to ruin the moment, too horny and tired to argue, just do it! She wanted to know what it was like to lactate anyway. Now she doesn't have to wander off to the water cooler at work to get a drink. If no one is looking she can just pop out her own tit and drink her own milk- her boobs are large enough that she can just roll the front up to her own mouth. Cow make milk, drink milk, make more milk- the infinite milk hack.

Her breasts drew closer to her body but bloated rounder at the same time, pulling themselves taut from internal pressure, the hair-thin veins inside fattening with milk. Her areola bloated as milk filled the reservoir in them, then her nipples grew longer and fatter with milk stuffed in them as well!

*Milkier.*

"Yea..."

*Milkier cow. Good cows make milk, and you are a VERY good cow.*

"Muhm... muh, huh? S-sure." Her face was so hot, blushing into her pillows.

Even resting against the bed, Gwen felt her breasts rocking with his thrusts now. Their weight increased, and the weight is entirely liquid- the hot milk rocked back and forth like waves in an ocean. It has no room to form actually waves, so it moves her entire boobs along with its own motion. Every time it rocked back, to where her nipples are pointing they tingle. Too much concentrated pressure, and she keeps making more, filling up! She isn't made to hold so much liquid, it's going to escape! Ah, but her bedding will get all ruined. But she can't hold all that! Still making more!

Vincent grunt and started to pick up pace- now making shallower thrusts at a much faster speed and the same force as ever, making her butt cheeks ripple with the impacts. Gwen's cock was already drooling cum in a lazy stream; she has not hit a full climax yet but Vincent's giant dong was milking her prostate. Her huge balls roll halfway up the scrotum before pausing and flopping back to the bottom heavily- unable to fully lift their own weight to her groin.

Still more milk! Her breasts are blushing... the pink makes them look more like udders! Her nipples pulse with the force of the growing tide of milk inside of her, like the milk supply is drumming on the inside of her skin to be let out! Beads of white start sweating out across the surface of her areola and now huge nipples. She closes her eyes and squeals, she can't take it anymore, too much pressure! She needs to be... to be MILKED!

Gwen hits orgasm and Vincent blasts his own illusory cum-volcano into her as her teats erupt with milk! A concentrated stream of milk from the front of her nipples and then a dozen hair-thick streams arching in various different directions from the sides of her teats like someone turned on a sprinkler system. The pleasure throbbed through her whole body, which caused muscle contractions which helped force more milk out- the flow throbbing with her pleasure too! The streams stretched her insides to get out, scratching the inside of her tits; a place she could never be touched otherwise. It felt so good to let it out. So much hot, creGwen milk! Like a good cow. Moo.

She woke up even before the sun rose this time, again not remembering having gone to sleep in the first place. Vincent was still between her legs, but his dick was just limp on the bed and not inside of her. There is so much cum, sweat, and milk soaked into her bed it makes a wet squelching sound when she picks herself up off it.

"Eeewww, laundry time..."

*Oh- no no, I insist!*

Her entire bed started glowing neon blue a moment, and the flow of condensed mana erupting off it was so powerful Gwen could actually physically FEEL it, like a breeze. All fluids once again turned to pure energy... eliminating the need to clean. At this point Vincent must have enough backed up mana that he could out-live Gwen herself.

Gwen groaned and leaned forward, her boobs lifting off from her to dangle freely and her eyes went wide at the sight of them! They are even bigger! Or... maybe not? The added size might have just been caused by her lactation- because it feels like she is filling up again. Their weight is certainly because of the milk, and her back once again hurts trying to hold these up!

"Nnngh, too big and heavy. C-can you, stop the lactation...?"

There was a long pause. *I can, certainly my dear, but... you-*

She lowered her head. "Need to want it first. Aargh what am I going to do?? I am going to be making milk all the time, and my tits are so huge my biggest shirt barely fits. If the shirts compressing them; as soon as I make milk it is going to leak out on accident and then wet my shirt, constantly!"

*You seem discontent with your job though, my dear? Perhaps the answer is to simply not go to work in the first place. You seem like you would be better off without.*

She sighed. "Money, Vincent. No money, no live. Being dead is very against my pleasure, which I am sure is a terrifying concept to you."

She felt a pulse, then a tingling concentrating in her breasts toward the front, becoming warmer as it travels, making her teats tingle and then she erupted milk automatically! She was holding the bottoms of her boobs up to ease the weight off her spine a little, and the milk rushed out between her fingers making her yelp.

*I believe you have a lucrative source of income already, the very same that the cows have. Sell your milk online.*

"I don't produce like a fricken dairy!"

*You also don't lactate bovine milk. Human milk is worth substantially more money.*

Yea, like, ten times the amount actually. Gwen rushed to the kitchen and was going to milk herself into the sink but with a grumble grabbed a bunch of glasses to temporarily store the milk in. It felt so good to lactate- her fingers tugging the tender, rubbery flesh from the outside while the jets of hot liquid tickle the insides as it explodes out into the glass! Being able to work from home... and have fun doing it. Why does Vincent have to be riiiight, stop being right damnit.

So, Gwen ended up just staying home and abandoning her post at the library. She was still inside all day, but now she could watch TV and game all day, while stopping every four or so hours to let a little milk out. It was easiest to manage if she milked herself before her boobs started to bloat up trying to contain it. Vincent managed to convince her to use him a bit more frequently, since she no longer had anywhere she needed to be, and half the time she did not even bother to make herself food. Her milk is only partially generated from her own body- Vincent keeps the liquid flowing no matter what with magic, which means she could survive off her own milk supply, and she has to milk herself anyway. If Gwen is just laying down on the couch or bed and her tits start to get a bit unmanageable, just roll one up latch on and suck.

She ushers him into her butt, her balls doing a little hop as he slides his giant bull phallus into her again.

"Moo~! Hehe. Good to get off my feet, even though I have been in the house. Can't imagine the foot cramps if I still worked, with my boobs this heavy."

*Wish you were better at standing all day, like a cow?* He grunt into her ears.

"Mmm." Her toes started to twitch on their own, and she felt the skin around her nails being pushed aside as they grew still larger! "W-wait, n-nnngh!"

*My beautiful cow shouldn't have to wait. Only us now. Take what you want.*

He started to thrust so powerfully he was nudging her up the bed! Over the pillows! She had to sit up, then she watched the indentations of his rear hooves scramble forward suddenly and his hips bucked, yanking her up off the bed entirely!! Vincent picked her up with his cock, sliding her up the wall! Front hooves on the wall beside her- she cannot see them but she can feel his hooves brush her upper arms. His thrusts now bounced her up off his sheath then back down onto it- her back against the wall, her bare breasts brushing the fur on his chest with her fat teats. If she has hooves her feet won't get sore... because she won't have feet. If she doesn't go out there is really no reason not to at this point, right? She can... think of something to turn back later, or, when he runs out of power and is un-summoned? Even though at this point he has enough mana to keep going for a century.

Her feet stretch longer, the bones expanding into one another, fusing together into a cannon bone. Her big toe regresses away, the outer two shrink and draw back to become the dew claws and the remaining two expand into the front segments of her new cloven hooves! The cannon bone also stole length from her shins, shortening them and changing the proportion of her legs a bit. Being suspended entirely on his cock didn't leave her much chance to resist the changes- her legs can't even touch the bed.

Vincent grunts again, she can feel his invisible head bow forward, pressing his forehead against hers, though his head is so long that puts his hot nose in her cleavage, grunting hot air into her tits. *My big cow, take what you want. As much as you want. Moo-re.*

She grasped his upper arms to brace herself, letting out what was meant as a startled yelp but instead came out as a moo! Her breasts tightened, and then expanded! No, not even bigger! She grew hooves to help support the weight, don't make them even bigger now and reverse it!

"M-moo! I moo- ah, I mean... I-hah, I... I-I ahnn-mmm-mMUH!" He was fucking her brains out at this point; too much pleasure, she loses her train of thought before she can say anything in protest!

It felt like her breasts were growing strangely at this point, like the bottoms were bloating out and not the top? They were not projecting any further out, but were lifting up and sitting higher in spite of their weight. Thanks to the force of his thrusts into her- her breasts divided when he thrust her up, across the new set growing below them!! She has C cups below her giant melons and they are rapidly growing to try and match the originals!!

"MOO! Wai-uh, wah....m-muh!" She kept switching between a distressed moo and an aroused moo as he thrust into her and scrambled her thoughts every two seconds.

Gwen is starting to drip milk automatically. All four nipples as long as her hands and as thick as a shot glass. The bottom swell pushing into her torso and the upper breasts, lifting the top breasts from below. When he thrusts her up- the top two divide slightly across the tops of the bottom ones. When she drops back down, the bottom divide against her torso to let the top two sink into the middle for a moment. Her teats are so long and fat now that they flop with their own rhythm, flicking more and more milk from their length. Their color started to change too, taking on a more diffused red coloration instead of their default dark brown. The top collide with the bottom and all four perpetuate the jiggling fit Vincent's powerful thrusts put them in. By the time he cums into her to mirror her own orgasm, the second set of breasts have matched the first in size. Too late to hold them back now. And the pleasure told her that she would not be able to will this change away, either.

Vincent climbed down and backed up, resting her down onto her newly changed legs.

Gwen furrowed her brows. "Moo changed moo- me again! Now I um too big to stand up straight! It won't mooter, m-matter if moo feet can take it if moo spine can't!"

He was going to mention the fact he accidentally made her ears bigger yet again but since she was already frustrated he just kept that little tidbit to himself. Her ears were already leaf shaped like a cows, but now they are massive and flop around beside her head from their own weight. The bone bubbles in front of her temples are now cones, still trapped under the skin.

He returned to his bell form. *Well, I know it seems like I am a one-trick pony at this point, but you know you could fix that by just... changing a bit more bovine.*

She grunt, lowering her head at him and stomping forward on all fours, not trusting her ability to balance on her new hooves immediately. Vincent saw her cock swinging around fully erect from the pleasure of her leaking collection of boobs swinging around under her, flopping around seemingly at random because they keep bouncing off one another. He turned female quickly for her master, immediately bloating enormous, forming a yoga-ball sized set of udders for her to 'punish'.

Gwen jumped him, slamming her cock into the bovine pussy and thrusting aggressively, as if she could actually make Vincent sore as punishment while curing her insistent erection. As she thrust into him though her forehead felt a sharp pain and the skin broke over her horns, finally enlarging enough to slide out into the open! Oop- no more hiding those. Vincent complemented her strength while moaning like a bitch in heat, and she groaned as her voice started to dip! Still feminine, it is now deep and womanly without meaning to! Her muscles started to pulse and swell up as she thrust into the udders, flicking milk all over the place from her own fat teats flopping around so much. Her arms and upper back especially swelling bulbous and huge! The muscle bulk of a bull, not a cow.

As her horns grew bigger and sharper, her thoughts grew duller and slow. They did not stop at short spikes- her horns continued to grow to the size of a bulls; growing straight out at first but then turning upward at the halfway mark. She made those udders explode with her cum again, but forgot that she was upset at him for the moment, and took a nap. Vincent certainly did not complain. He was also unaware that the growing horns altered her mind to be more bovine as well- making it hard to keep a train of thought and easy to become distracted. Between the four giant breasts and the monstrously giant cock- most of the distraction is already provided.

She started to fuck Vincent in both forms more and more- forgetting why she was trying to resist in the first place, and forgetting there were even any options of things to do outside of her place. She grew even bigger, and more muscular, ripping the last set of clothing that still sort-of fit her. More sex, less other activities. Her freckles expanded, absorbing one another to form huge brown splotches across her body, consuming her entire right arm, the middle of her back, and both of her lower legs making it look like she was wearing stockings.

As the days went by her breasts started to grow a little bit bigger with each milking, and her spine got a bit longer from her overall body growth- forcing Vincent to consciously alter her hips further, making them the sharp V shaped pelvis of a cow, but locking her onto all fours. Her body was just too lop-sided otherwise, she could not keep balance on two legs. This of course immediately put weight and strain onto her wrists and hands which are not meant to be used like that at all- so within a day he also devolved her hands into hooves. Her mind had simplified enough at that point that she was happy he fixed the soreness, and oblivious to the fact that she now cannot hold or manipulate objects anymore.

Stuffy feeling in her nose, then the next time they fuck the bridge of her nose pops- finally giving up resisting the expansion of her nostrils. The red-pink coloration of her lips expanding across the front of her nose as the bottom of her nose grew forward to meet her upper lips! She started to get off even without Vincent's help. On all fours- if she gets a full erection her disturbingly giant member spears her own quad-cleavage, allowing her to tit-fuck herself on complete accident. Her face started to stretch out, her words slur because her mouth shape is incorrect for speaking human language.

Gwen started to devolve more and more feral, turning into a strange mix of both cow and bull. The front of her body grew nearly twice the size as the back- the enormous muscles of her upper back almost making her look like she has a hump. Her breasts swelled even larger and milkier, filling with more milk at an unheard of speed. The breasts started to permanently blush pink and her nipples and areola faded to a diffused red, then magenta, before finally pink... matching the rest of her breasts. Her nipples became a bit darker toward the ends, remaining slightly magenta, but the base and her areola matched her breasts exactly now, making them invisible.

One day while fucking Vincent's udders form, bouncing his tits between her legs, wishing she had an udder that impressive- he granted her wish. With a gurgle then a wet, stretching sound her breasts expanded rapidly, but had already run out of room to grow into. So, they grew into each other. From the base up her cleavage became shallower as she thrust into him, swinging her giant breasts heavily in the process. Her four breasts merged into a giant cow udder! But... her crotch was already occupied... so it didn't move, it remains on her chest.

More sex, more changes; Gwen grew larger still, her face stretched out, and then her neck bulked up with muscle trailing from her already massive upper body. From her hooves and crotch patches of fur grew in and started to spread across her quickly, but that grew in strangely too. Her bull pelt was black, but the cow pelt is dark brown spots on white... the result of them mixing is her fur is black with dark brown splotches... which, isn't a color scheme any normal bovine has. The bottom of her neck became layered in thick folds of skin, forming wobbly dewlaps, and her iris expanded to hide the white of her eyes.

Vincent was not sure if he should be glad his job is done, or upset that his job is done. Gwen seemed to have regressed to full feral... or as fully feral as she can be while jumbled together. The tassel on her tail is perfectly flat, straight hair and freakishly long for a bovine, and she still has the same type of hair on her head even though it's surrounded with normal bovine fur. She has a giant blue ribbon dairy cow udder but it's between her front legs instead of the back, and she has a bull's balls and cock between her back legs, but over twice as big as the biggest bull there ever was. The loose scrotum drags on the floor under her even when fully standing, pulling along a pair of balls the size of a honeydew melon each. When she gets horny she prods her own udders and then just immediately starts thrusting away without a second though... which means she does not need Vincent anymore.

So, Vincent is out of a job, but also... job well done? She has plenty of pleasure, and doesn't seem to be worried about anything, or, even have the capacity to worry in the first place. But also, what does he do now? He won't naturally dispel because he has far too much mana stuffed into him. A toy is made to be played with- but he made Gwen's body so fun that she just plays with herself.

Luckily- a man from maintenance unlocked the apartment door to find the cow-bull wandering around. The woman from the apartment below complained because Gwen has been gushing so much milk all over the place it actually soaked through the floor causing flood damage and dripping into the apartment below! The man ran his fingers through his hair, not even sure what to make of the strange creature in the apartment, but knowing damn well the mess it's made is going to be hell to clean up after. Vincent smiled to himself internally. He looks like a fellow who could use some stress relief! Vincent happens to be a master of a relaxing, new bovine therapy!
