"Has anyone seen Heather?" Laura asked as she exited the barn to her coworkers chatting out front by some hay bales.

The two women, Vanessa and Gisela, gave a mutual perplexed shrug. Vanessa, Heather's best friend, was the one who answered though. "Haven't seen her around. We were actually trying to find her ourselves to see if she wanted to grab lunch with us. She said she was on muck duty in the stud barn until noon."

"Yeah, she was complaining about it most of the morning actually. Figured she'd either have it done or be ready to leave," Gisela joked.

Laura sighed and removed her hat to fix her mussed hair. "It's just her second week here and she's disappearing? Is this common for her? I know you're practically her best friend, Vanessa," probed Laura as she tried to be a good manager.

"What can I say? Heather is tough, a hard worker, kinda stubborn, but a great person. She has had a habit since back in high school of, erm, disappearing for usually short periods of time," explained Vanessa in as kind a framing as she could. She had known Heather since they were kids so she was used to her friend's proclivity for wandering off and getting distracted. There were running jokes about what Heather did but it was a harmless foible usually. "But when she does it's usually because she's distracted doing another task that needed doing. She'll turn up soon I bet."

"Oh yeah, definitely. Just wait around and she'll show up," agreed Gisela who was also used to covering for Heather. So she diverted the cowgirl's attention. "So Laura, I heard you and Reed have been on a few dates now. How's he holding up in your estimation? Dude is a hottie if you ask me."

As the women talked and her friends covered for her Heather Schultz was stealthily listening in on everything not too far away. Seated behind the hay bales next to the farm, her legs spread, black short shorts and white panties down around her knees, and two fingers on her clit was the person they were looking for. Indulging her fetish for risking it publicly to try and reach a quick orgasm before lunch had turned a bit steamier than she anticipated with Laura's arrival. But that only made her all the more aroused while trying her best to keep quiet.

'That's it. So close now,' Heather thought to herself as the heat of the moment sunk in. Aged twenty-three she was new at the job but already finding ways to sneak in her private kink whenever the moment arose. The tall, athletic brunette with a fair complexion tanned by summer sun was big in the chest and bubbly in the rear. For work (and play) Heather had her long hair back in a ponytail, a gray tank top and sports bra, aforementioned shorts and panties, sandals, and blue nail polish on fingers and toes so round out her look. Only thing missing now was her orgasm. 'So fucking close. Keeping talking girls,' Heather had to stop herself from actually telling them.

"... And then on the third date we finally got some proper alone time," Laura confided with allure in her voice.

"Finally. So how was he then? Are the stories true?" asked a very interested Gisela.

"If anything the stories were underestimating, girls. Reed would put a few bulls we have to shame. I honestly just stared at it for a minute like the first cavewoman at fire. Once we actually got to it he proved he could use it too. Couldn't git it all in but I ain't no heifer either," joked Laura. Sparking laughter from all friends except Heather who had been more fascinated with the confirmation of the rumor that Reed, a well-known cowboy on the farm, had as big a set of nuts and bolts as a bull. A thought turned her on in the right ways as Laura continued, "He had a lot more stamina than a bull though. Both in knowing how to last and being ready to go while my hips were still twitching from the last one."

"Damn, Laura. I love that you don't know what the meaning of 'oversharing' is. And keep it down, some of the bulls might hear you talking like that," giggled Vanessa while thumbing at the barn next to them. "They're doing collections all day in there and if the bulls start feeling inadequate Miss Fayebrook will be pissed," she teased.

"At who? Reed or Laura?" Gisela asked amid her own amusement.

"Me, obviously. Not like Reed can help it," a blushing Laura observed.

"No, but it does lend some credence to that other rumor about Lee then," Vanessa hinted.

Laura scoffed and waved the suggestion off. "If you're talking about the rumor with Milkshake Machine then I think it's just that. A dude that fucks like that isn't going to be that desperate. Some of the other dudes on this farm though, I wouldn't put it past them," Laura stated in defense of her new boyfriend.

Vanessa and Gisela were unconvinced.

"I dunno, I get the impression dudes will stick their dicks in anything. When no girls are around I bet-" Vanessa stopped mid-sentence when she and the others heard a lusty moan that itself cut itself short. "What the? Did you both hear that?"

"Yeah. Was that one of you?" responded Gisela as she and the others looked around for the source.

"Not me," said Laura.

"Don't look at me. Probably some sound from one of the herds or barns, right? Weird sound for a cow to make," an amused Vanessa noted. "Whatever, where was I?"

"Uhhh, men fucking anything?" suggested Gisela.

"Oh right," Vanessa remembered then carried on with their gossip.

Feet away Heather was still squirming from her orgasm with one hand firmly over her mouth to prevent more moans escaping. The thought of a well hung Reed using the artificial bull mount- or The Milking Machine as it was known around the farm- seriously or not was enough to push Heather over the edge she wanted. It had been risky but the thrill was in being almost caught. Much less at her new job by her boss when she was supposed to be cleaning after the bulls in the barn. But she couldn't pass up the opportunity with the hay bales right there. Heather reveled in her climax for long enough that she only came to her senses when her friends could be heard leaving.

"It's Heather's loss for lunch I guess," Vanessa could be heard saying.

"Guess so. As long as that barn isn't a mess when I check later I don't care what Heather is off doing. Now where exactly were you two going for lunch? I might wanna tag along," Laura hinted.

Heather gathered herself as she listened to their voices soften until disappearing into the many sounds of a busy dairy farm. That was her cue to check to make sure no one was looking in her direction. When it was clear no one was peeking she snuck out from the hay and back into the barn to take care of the task she'd been sent there to do.

"Have to remember to fool around after I get the work done next time. I'm not looking forward to shoveling with this weakness still in my knees. Fuck that was good one," Heather remarked bluntly of her orgasm. She moved slowly to grab a shovel and rolling bucket. Then trod herself over to the first of the stalls to be cleaned. "Ugh, goodbye to my appetite," groaned the woman as she got to work.

The moderately sized barn had some fifteen stalls with just three occupied with a couple younger bulls and one older one. Others had been through in the morning and despite short stays in the stalls had managed to leave sizable manure piles. Heather had trained herself to get through it without gagging anymore but the stink was still atrocious and one she refused to truly get used to. It provided good motivation for her to work quickly if nothing else.

Didn't take long for Heather's bored mind to wander back to earlier with her recalling Laura's comments about cowboy Reed's impressive manhood. Notably the rumored fling with the bull mount. It was pulled out and set up towards the center of the barn but was far from impressive. It wasn't much more than a bunch of gym maps wrapped around two reinforced steel beams which were anchored to the barn floor with straps. On the business end was a custom built semen collection unit that could satisfy a bull in seconds like no heifer could. She'd never gotten close enough to know much more than that besides where the fridge was where they kept all the collective bull seed. That was humming loudly in the corner during an especially sweltering day.

She got one stall down and moved to the second when curiosity got the better of her. Setting her shovel down Heather walked over to the bull mount. It did strike her to check if anyone was coming but in shirking that precaution, Heather turned herself on. Explaining why when she reached the mount she mockingly assumed the position behind it as if she were a bull. Sadly for her it was set too high for her to realistically penetrate the mount with her phantom impressive cock. It did give her an easier time of seeing the realistic bovine entrance contained within a secured length of metal piping. Numerous danger signs reading: 'Bulls ONLY! Any caught will be promoted to FORMER employee IMMEDIATELY!'

Heather chuckled to herself. "So it only counts if I get caught, huh? Well never thought I would say this but I hope I don't get caught for once. Cause I really need this job," she joked, though she was right.

Some further inspection to see where the collection unit was underneath showed Heather where the height of the entire mount could be adjusted. Having come this far and making sure this time no one was about to walk in Heather turned the small hand crank which in turn lowered the height. She stopped when it lined up with her crotch so that she could replicate the horny image in her head. One of her thrusting into it like she was Reed or some lonely farm boy. Heather would take a selfie too as a memory for later.

"Cheese and curds," Heather smiled as she took the selfie of herself mock humping the mount. Done tastefully with her pants on so she could share it with friends at a time when it leaking wouldn't cost her a paycheck. That done Heather moved on to kinkier shots just for her own collection where she pulled her shorts and underwear all the way down around her ankles. Then took some more photos of herself fucking the bull, few with her tits out, then set the phone on the floor so she'd have two free hands. "Time to have some real fun," she purred while fingering her moist, shaved slit.

Always one to get into masturbation led Heather to imagining herself as one of those well endowed fellas that could actually service things. So she worked herself closer to an orgasm then grabbed hold of the mount with both hands and pressed her crotch right against the fake cow cunt. Either from her or some leftover from the morning meant the rubber entrance was warm to the touch. Something about it made her clit throb for more so Heather held nothing back.

"Yeah, you like it, you cow? You thought Reed was something? Milk Machine meet the Fuck Machine," Heather remarked with a head full of horny. A sort more intoxicating than she was prepared for but didn't stop her hammered thrusts. She just clothed her eyes and focused on getting herself off. Humping and humping and working it until it felt like her whole crotch was plunging in each time. Stopping when she reached that climax by burying her envisioned cock in the mount. "Yesssss Oh fuck, yes!" she moaned along with other lust fueled phrases.

Her orgasm hit especially hard and Heather did hold back at being loud about it. Heather's grip on the mount squeezed with every spasm while she slumped to lay her whole upper body on the pads because her energy was sapped. All the while feeling the most sublime pleasure pulsating out of her clit like she'd never experienced before. So it was close to five minutes before Heather could summon the strength to push herself back up and back away from the mount.

"Damn. I think I get why a bull or a dude might like that. Haven't cum that hard for that long in- Wait, what the? Is that a...?" Heather had a rare instance of being at a loss for words at the startling sight of several inches of moist, soft pink skin. Drenching in a salty, viscous fluid that oozed off it, the growth extended from her clit and the surrounding area out five or six inches. The base was as thick as her thumb and narrowed to her pinky's thickness at the tip. Alarmingly the growth was actually still developing. As were other changes further down around her labia and vagina. "Wh-Wh-What is happening? That thing looks sorta like a dick? And it's getting bigger... Shit, I need to lean against something," she told herself in amazement.

Returning to the bull mount for stability, Heather crawled to the side and leaned back on it so she could at least see what was happening. She watched in stunned silence as the shaft of her correctly presumed penis extended to twelve inches and then continued past that. The more it grew, the thicker more of it got with the glans at the narrowed still and the end becoming a tip. Such rapid growth melted away the remains of her pussy to form more of a shaft. There was darker, wrinkling flesh massing at the base too but Heather's attention was pulled further down. Where the changes had seemingly sealed the woman's vagina; with a mixture of ballooning sides of her labia and a tightening of her vaginal canal and cervix that had done it. Both sides of her labia had abnormally swollen up with two oval shaped somethings inside.

"Fuck, balls too? Where's this gonna stop?" a shivering Heather asked whatever force was doing this to her. Unexpected as it was, she couldn't help but have curiosity about what was unfolding in front of her. She let it happen and just hoped things didn't get painful. Since for now it just felt like more crawling skin, numbness, and arousal.

With every thump of Heather's heart her new cock and balls grew in size and weight to her eye. When the penis was near twenty inches and her balls were softballs she thought that would be it. But they grew bigger and bigger beyond what she thought could happen. Heather had noticed the bestial appearance of her shifting genitals from the start and now it was uncomfortably clear it was a bull's penis and balls that she was growing. She immediately looked at the mount she was leaning on in a new light.

'Is this thing magical or something? Not sure how else I can really explain growing bull parts like these. It feels so real,' thought Heather as the weighty bull's equipment weighed her crotch down. There was a small strain on her body but the thickened fleshy hide that had formed the base of the bull's sheath spread to her groin and rest of her crotch. Making it easier to bear physically while the mental strain was making Heather awfully conflicted. 'It really is real. Feeling turned on but never this before. Such a raw, feral sensation I'm getting. Feels like it's powering up?'

The notion came as her beefy balls sagged between her knees where they pulsated and twisted continuously. Hormones from here were flooding Heather's normal brain with hormones fit for a bull. Their impact on the woman's mind was hard for her to be fully aware of beyond the flush in her cheeks, the need in her new bovine cock, and a desire to bury that cock someplace nice and warm. So she wasn't very aware of the true pervasiveness of it on her psyche. Leading to Heather overcoming her hesitation to stroke her new cock with one hand. Then two.

"Ohhhhh oooOOOoooOOOO! This thing is more sensitive than I thought. Not really as gross to touch either," a delighted Heather told herself as she gave in to those new urges without a fight. It felt so good she wasn't inclined to ever stop. Her human brain swooped in and made Heather stop and stand up again Because she had a better idea. Waddling over to the business end of the mount Heather gave a snort. "Now I get to see how it really feels."

Heather lined herself up with the machine with her overextended two feet of shaft then slid herself in as far as she could possibly go. She moaned the whole way and only stopped when the unit was stuffed and she had a firm grip on the mount with both hands. Then it was simple bull instinct that drove her speedy repeated thrusts. If the first time she'd fooled around with the mount she had been into it, this time Heather was lost to lust. Being caught or looked at never crossed her dulled mind in those moments with the only concern of Heather's being knocking up the heifer under her.

Fully invested as she was, the furthering of her own changes went unnoticed. Especially with the enlarging bones and larger muscles in her ass and hips helping in her current mating needs. A growing bulge at the base of her spine was easy to miss even as it extended more inches into a tail. Things that she should have noticed like her fattening nose and enlarging ears didn't seem all that pressing compared to burying her penis deep when she finally came.

"So gooooooooOOOOOD! Fuck yeah! Take every drop!" Heather bellowed in a deeper, coarser voice than her usual.

The ecstasy went on and on for Heather while strength in much of her body ebbed. Leaving her flopped forward on the mount, a satisfied smile stretched across her widening face. Spilled or excess seed leaking out of the unit since there was nowhere for it to go. It made Heather feel she had really cum the buckets that it felt like she had. Took her cock softening up and retreating as far as it could for Heather to pull herself off of it. That's when she noticed that her bullish transformation had stopped between her legs.

"Woah, shit. I thought I felt something tickling my butt. A tail too? And my ears? I don't know if this is getting out of hand or... damn it. Do I like this?" Heather had to ask herself. There was enough human reason knocking around in her head for Heather to know things could get out of hand easily but couldn't reason herself out of not desiring for more. Some aching in her pelvis and ass was making standing a little hard but nothing she couldn't handle. Cramping and the eventual bloating of her bowels gave her real trouble. "I guess a bull cock doesn't mix with a big breakfast," she bemoaned with a hand on her distended gut.

She looked around for a place to possibly relieve herself when Heather let out the loudest, longest, and most foulest smelling fart of her life. Gross as it was once the flatulence passed the fullness of her bowels relaxed to a comfortable level. Heather could breath easier despite the stink knowing it was just gas. Allowing her overstimulated bull horny brain to return to idle thoughts while touching herself. Remembering her risky masturbation near her friends earlier got her juices flowing. A desire to try that again with her new equipment stirred Heather to waddle over to where she left her cellphone.

"If they're back by now then I know where they're probably eating," mused Heather as she scrolled to her most recent missed messages from her friends. She got to the end where just as she predicted they had texted to say they were eating lunch in their usual spot. "Perfect. Can sneak there easily. Once I get some pants at least," she remarked.

Heather put on some rubber overalls and boots- she knew how muddy the route she'd be taking so set her sandals aside one at a time- which at least hid her most prominent bull bits then headed out a side door of the barn after making sure no one was about. Her and her friend's preferred lunch spot was the leeward side of the barn they stored old equipment in. Several oak trees lined that side making for a shady, secluded, and pleasant smelling part of the barn. This worked in Heather's favor as the spot was reachable by going through the alleys between buildings and hay stacks. Limiting her exposure to anyone else at the expense of the cramped and muddy spots. It was worth it to come up between the storage barn and another building hearing Vanessa, Laura, and Gisela's voices just around the corner.

She peaked carefully around the corner of the barn and saw all three of her friends along with another farm hand, Jenn, eating lunch. They were sitting on the concrete entrance of the barn with the nearest backs of Laura and Gisela turned to her. All the opening Heather needed. She rolled her shoulders, letting the rubber overalls fall away leaning her back against the corner of the barn; tempting safety by allowing her ear and foot to hang out where they could be seen. Heather's concern was more on stroking her bull cock hard again. Small farts snuck out from behind her but Heather was sure it was nothing but more gas.

Satisfied with simply stroking herself for the first few minutes she listened Heather got her cock rock hard along with a horny buzz. Further eroding Heather's restraint and reason for the sake of bullish bravado and fueling lusts. It's why she was getting lurid ideas of beastly acts and rather than dismissing them she prepared herself to have some fun.

Unaware of their friend's bullish presence the group chatted on the topic of Heather by chance alone.

"I'm just saying she's flaky as fuck. Cute though," Jenn remarked to the others.

"Heather is a mess most of the time but she's a good people. Just don't get her drunk," Vanessa said smiling.

"Oh man, drunk Heather. She's something else," agreed Gisela between sips of her iced tea.

"What? Is she worse when she's drunk I guess?" assumed a curious Jenn.

"Not sure worse is the word I'd use," Laura began.

"More like a total horndog! I'm pretty sure drunk Heather would try to fuck one of the heifers if it mooed at her seductively enough," Gisela joked. Herself snorting with laughter remember Heather's past exploits.

"Yuck! She's that bad?" Jenn questioned since she was unsure if they were exaggerating. Jenn had only bed Heather in passing a couple times so her confusion was genuine.

"Not that bad, jeez. Give Heather some credit, Gisela. She mostly just- oh gross! Tell me that wasn't one of you!" Vanessa had been defending Heather again when they all heard a loud series of farts which grew wetter more bovine as they went. Then abruptly cut off. Not before A few seconds later the foul aroma of cow farts wafted over the lunching workers. A stink so disgustingly pungent that Laura was forced to spit out her food and Gisela her tea.

"Wasn't me!" Jenn blurted out first.

"Not me either!" a coughing Gisela said next, wiping her lips clean.

Laura didn't answer at first, preferring to look around for the source but not seeing any cows initially. "None of us couldn't have made a sound or stench like that. Cow or something got out," reasoned Laura liked the experienced farmhand she was.

"A cow?" Jenn asked as she stood and looked around for a source too. "It sounded so close so where is it? On the roof?"

The strange suggestion had Vanessa and Gisela looking up all the same just to be sure. All four of them were looking from where they were but failed to notice the side of Heather's boot that was sticking out from around the corner. Heather had tempted fate by letting some of the pent up gas out. She was mostly hidden by the time her friends went looking for where the cow farts came from. The close gross call had Heather furiously stroking herself with right hand. Normally she'd use both but the other was over her mouth and nose to stop her giggling laughter being heard.

With no sight of a cow or bull to blame, all four were forced to sit back down to finish their lunches. Heather saw her opportunity to have more fun. "Just a few more," Heather told herself before letting out more stored farts.

She could hear her friends gagging and moaning about the smell almost immediately. Rather than pull back Heather pushed harder, trying to manage the biggest fart yet to see how'd they react. She had to really push to get it out and what started as a fart became solid clumps of cow manure that tumbled out of Heather's butt and into the seat of her overalls. The sensation was so unexpectedly pleasant that Heather didn't try to stop herself when she realized what she was doing. Letting more farts escape, causing shit to splatter on the side of the barn behind her.

"It's coming from over here!" Vanessa called out to the others from what felt like just over Heather's left shoulder.

Heather's heart jumped into her throat, breaking her trance and bringing her human logic back. There was only enough time for Heather to hastily clench her asshole, hitch her overalls back on, and take off running down the alley. Remembering they could be behind her at any second Heather threw herself behind some rubber barrels and hoped no one saw her.

Her luck held and Heather had hidden herself just as all four women discovered where she'd been masturbating before. There were twenty feet between Heather and her friends who were still oblivious to her presence.

"You were right about hearing a noise, Vanessa. What the hell was it though?" Laura asked, looking at the manure pile.

"There were footsteps too but you guys were shouting and I don't know what I heard. I don't see anyone down there," a flustered Vanessa observed.

"I see some boot prints," Jenn said while pointing to the set leading away from the mess and down the alley.

Causing Heather to feel a rush of arousal despite the actual danger. What was making her really sweat was the manure that was piling up inside her wanting to get out. A base instinct wanted her to just relieve herself like before but Heather couldn't risk it now. She was left to hope to go undiscovered and then run at the first chance she got. As she waited, clenching her backside, Heather did the best she could stuffing her erect bull cock into her overalls. Since otherwise it would be in her tits and face the whole way back.

Jenn and Gisela tried to follow the boot prints but were dissuaded by the mess of footprints around the barrels and supplies beyond Heather's. The thick mud was also scattered with more manure that had them both checking their sneakers if they stepped in any.

"I'm not sure what it was but the trail kinda leads to where the workers leave the chemical barrels. Could just as well be footsteps from anyone," Jenn explained as she and Gisela trudged back to the other two.

"Well this mess definitely wasn't one of the workers," Laura chuckled.

"Could it have been a calf?" suggested Gisela based on the height of the stains on the wall.

"Actually not a bad guess but where did it go? If it ran down there it wouldn't exactly be invisible," Laura wondered after pointing down the muddy alley.

"Whatever it is, I think it's someone else's program right now. Can we finish out lunch? Maybe eat somewhere else?" Gisela hinted to the rest as they puzzled over the scene.

"If it's a loose calf we should find it," Jenn said responsibly.

"We should but we don't have much evidence besides that pile of shit. Plus we have twenty minutes of lunch left and I don't want to waste it doing Where's Cowldo," Laura grumbled having checked the time. "Come on. Let's go eat by the parking lot. Just a diesel smell there."

"Anything but this wretched stench," agreed Vanessa.

Gisela and Jenn gladly followed their friends back around the barn. Giving Heather her opening. She got up and jogged away taking short steps at first for fear of shitting herself. But as the fear bloomed into arousal excitement her stride got longer and her thoughts drifted back to the Milking Machine.

'Another round on her would be grand,' Heather contemplated as she went. Then as her destination came into view the urge to relieve herself bubbled up again. Her mind bull horny again meant she saw no reason to not go. Manure was soon piling out of her and into her overalls. Some solid, some wet, it was filling up before Heather could stop herself again. 'Pull yourself together, girl. The door is just over there, I can hold it. Easier to clean up inside,' rationalized the woman. 'Still so much in me though. I'm a fertilizer stud I guess, heh.'

Heather's simple thinking amused itself as she sauntered up to the side door with only a cursory glance around her. Inside felt such an ache in her bowels that she couldn't hold it for long. So she stripped off her overalls and boots fast as she could- ignoring the crap that spilled out all over the place. It did gross her out on some level but she still stepped through it with impunity. Spying the nearby stall that she'd previously cleaned out, Heather shuffled over to the best of abilities. Making sure to step into her sandals again along the way. Doing so out of some faint sense that she needed something on her feet when in a barn.

Nearing the stall Heather looked around having not done so when she entered. Thankfully the only ones looking were the three bulls. All were gawking at Heather while taking heavy snorts of the air wafting off her. As she stepped in she relaxed and allowed a mostly silent fart slip out.

The fetid, pungent stink of manure that followed wasn't so restrained. Once she was safely inside the stall, Heather let out less and less restrained farts to relieve the tightness she felt. Heather leaned forward over one of the walls and stuck her rear end behind her for what was coming. The puckering of her asshole had happened midst the other changes to her butt crack and the transformation was more than just cosmetic with the stink coming from it. Proven further when Heather started happily pushing out larger and larger clumps of real bull shit.

"Ahhhh, better," a burly sounding Heather cooed as she relieved herself. As the pile grew Heather would shuffle down the wall to start a new one. The feeling was good enough to warrant her urinating to take care of that pinch in her bladder. Her dick's position meant the hot piss squirted all over the way she was leaning. Causing much of it to splash back on her. And to that Heather told herself, "Whatever. Feels good." Her mind was too busy drifting back to her little eavesdropping on her friend's lunch. The memory stirring up the intermingled lusts of Heather's new desires. Heather had no problem letting it happen because it made her feel good.

That's how she bore the transformation targeting her head more. Heather's nose kept swelling and spreading more than just itself across her face. The rest of her skull was being pulled apart in a painless but still a bit dizzying process that made the whole thing more massive. Her ears were protruding and getting longer and wider which can be said for Heather's tongue too. The changes had given her a slight snout but not enough to hold the darkening wetness taking the tongue. Its pointed tip she could see when it was strong and flexible to raise up in front of her. She proceeded to amuse herself with her new tongue while pooping and pissing a bigger mess than she had cleaned up.

"Heh. Muay toongue is shco big," a bemused Heather chuckled as she amused herself.

In the time it took her to empty her bladder and bowels enough to satisfy herself, Heather was bulging with beefy mass from her knees to her stomach, well hung by even bull standards, and a dark, hairy cow hide. Her tail was close to full length but mostly hairless above a soiled backside. With how her body was realigning Heather's legs were more under her. The more bovine her butt got the harder it would be to stand but she wasn't much concerned about it. Given a sudden but not unwanted spasm of titillation. Enough to get her dick sliding from an even longer sheath.

"Horneee," Heather grunted followed by a snort. She shuffled out of the stall and away from her mess with her mind immediately going to the mount to have fun. But as soon as she left the stall, letting go of the wall for support, Heather lost her balance; falling first to her hand and then her side. She managed to not hurt herself, laughing in fact as she tumbled to the floor, and pulled herself up to a very awkward seated position with her back against the open stall door. "Caaayn't walksh theres. Havsh to jush playsch wish myshchelves hers," she said with difficulty thanks to a wet and sometimes unruly cow tongue.

With her legs hefty and bovine now Heather couldn't properly straighten them out to be comfortable. That didn't stop the view from being an intoxicating one. The well muscled, massive haunches browned in their cowhide made her massive genitals look right at home. The tail, stink of cow manure, and sheath stitching its way up her belly made it all the best and spurred her cock to spill out all the way. This brought it well within range of her new tongue. Heather didn't need to think hard to know what to do; wrapping her tongue about the shaft to taste and to stroke.

'Now this is something else,' Heather thought while she blissfully worked herself in an all new way. She would bring her hands up to help but her fingers were getting stiff so a tongue bath would be it. Which was more than enough to get Heather to orgasm yet another time. In the time it took to reach that more shout came in and her horns broke the surface of her skin up above her ears. They pointed outward at first but would curl up slightly as the diameter increased. Growing these horns didn't slow Heather's masturbation anymore than her tank top and bra ripped apart. Happening thanks to those broadening shoulders' timely strength gained from her growing neck and shoulder area.. 'Clothing annoying anyway,' reasoned the woman.

Her hands were still good enough to pull those bits of shirt away from her and she rid herself of anything constricting. The one remaining article of clothing was one of her sandals that had stuck with her this long. Heather's feet were discolored but still human. With her ankles swollen it wasn't going to last. Nothing in Heather's mind cared anymore about clothing or how she appeared to anyone. She was moving from one basic instinct to the next with a big smile on her face the whole while. Things got better when her longer snout allowed Heather to tongue her own balls. A revelation as far as her bull brain was concerned at this point.

The taste, the heat, and the rich aromas coming off her own body were all Heather needed to reach orgasm. Her bellows this time deep, rumbling, and devoid of anything like speech. She may have been capable of it still but it's not what Heather had in her chest when it came out. Doing so took her tongue from her balls but left the taste for her to savor as calmed from yet another bullish release.

As Heather came around to herself this time she was amazed to see herself so burly and hairy. It would have shocked her to see a few hours ago but a lot had very literally changed so she was anxious about what would come next. The transformation was becoming a truly willing adventure. Seeing the merging of her fingers and shift of her hands to hooves and thinking hooves would make her a lot more stable. The blue painted fingernails being absorbed with the swelling hooves taking over the bovine toes that had taken over.

Heather's attention swung to her feet when the tingling and swelling there intensified. Her ankles by then had merged to shift up higher on her new hind legs. Slowly each foot came over swollen with patches of hide and hair down its new length. Each of her pinky toes and one beside it merged and after that two larger toes took shape in the front while the other digits came together was what became the back of her new hooves. They deformed wildly, the blue of their nails also disappearing into a light brown and gray mound of keratin. Which would darken more as the transformation progressed but Heather had no intention of waiting that long.

Figuring that her hooves and limbs were ready enough Heather rolled over from slouching and got all fours under her. Then with a heave and some wobbling she did it. In her current state though the wobbling would continue since as big as Heather felt she was in reality she was barely five hundred pounds with a lot more muscle, fast, bone, and meat to pack on. But the silhouette was bovine and every minute that passed the gap between Heather and the other bulls in the barn closed.

'Oh yeah, get bigger, bigger! I need more! Need to... feel it. I'll be so strong. So virile and, and, and best! Yes! More, more, more!' Heather's one track thoughts pleaded with her body.

Soon Heather's spine stretched it full length from horned head, broad neck, thickly muscled barreled body and trunk, and ending in the tuft-tipped tail hanging over his backside. Her stance widened to match shoulders and hips and wouldn't stop needing correction until all eighteen-hundred of her destined pounds was reached. Creating a lot of area for the advancing cow hide to cover. The hair's were rich dark browns that added another layer to Heather's scent. Adding to further by more manure and urine which the woman was happy to relieve herself of.

"Ngh, huff, big- snorts- bull," Heather remarked of herself in a gravely, barely human voice. Her skull had mostly shifted into the long, sloping forehead down the broad face and wet nosed muzzle. Naturally her eye sockets had grown with her eyes bulging in size to fit. Altering Heather's vision along with transfiguring her eye into the simple brown of a cow. Lining her mouth were yellowed bovine teeth that had replaced her old ones sometime during Heather's fun with her tongue.

The clatter of her hooves grew louder as the hooves themselves bulked and hardened to properly support Heather. Then came the hundreds of pounds of hulking muscle, fat, and heft that pushed her to a larger size than either of the watching younger bulls. Larger in other ways too as her lengthy, hairy sheath traveling midway up her belly and the protruding, unaroused cock hanging under her showed off. Working extra stomachs and massive other organs slumped her belly somewhat. In addition to inducing a thirst and hunger which Heather let bring her over to the large container of feed they took from when feeding individual stalls. And she had it all to herself.

Heather's gorging packed on more pounds but at least satiated the growl in her bellies for a time. A water bucket took care of one thirst as another was being riled up yet again. Snorting, snout dripping water and saliva, Heather's attention fell back to her old friend the Milking Machine. Weighing seventeen hundred pounds and gaining, the unit did not appear so big to her as it once had. It had gained some allure in her eyes which only grew when she was coming up from behind it. Bull seed from her last time was still draining from the end. Making Heather feel like a proud, virile bull like her body wanted.

The Heather that came up hot and horny this time was unrecognizable from the one that first wondered after the bull on two legs. Stout, massive in weight and presence, with a raging erection that needed quenching there was only a little bit of human reason left in the former woman's head. And it wasn't doing much more than thinking, 'Must fuck. Feels so good to fuck when you're big.'

It required several mounting attempts for Heather before she was finally able to get up properly. After that it was another few errant thrusts then proper, satisfying penetration. Instinct took over from there. Bull lust was given into without any resistance from Heather. Somewhere in the dim corners of her mind there was only enough awareness to recall that had successively proven that a well hung male could fuck a mount. It didn't take her very long to orgasm but it felt no less thoroughly satisfying as the rest. Giving her no reason to pay attention to the completion of her transformation. Which had finished not long after she did with the last few pounds lumped on an already gargantuan frame.

Fifteen minutes afterwards Vanessa and Gisela, who had just returned from lunch, entered the barn in search of their missing friend. Inside they found a big mess. Piles of manure and piss were everywhere. The bull mount and collection device were damaged. One of the bulls was out. And no sign of Heather except for the two sandals they were able to recover.

They came to be staring at the 'escaped' bull which was in fact their lost friend Heather. She had her head down in the feed again and was gorging without much thought to her friends' presence. Farting and shitting more manure that kept Vanessa and Gisela several steps away.

"I don't see any tags, markings, or even a brand on him," Vanessa remarked as they observed the bull.

"Seems pretty docile though. Should be able to coax him back into a stall at least," reasoned Gisela. Though she was wisely hesitant to move on the bull as it ate.

"Could be. Doesn't explain where the hell Heather is though. If that girl flaked out I'll- woah, big boy. Easy," Vanessa told the bull as it turned its head.

'My name Heather,' thought the bull in reply. On some level Heather remembered her friends. Making her trot over to greet them, tail wagging.

"Seems like he likes us. As long as he isn't charging us, let's just get him into a stall and try to ask around if anyone has seen her. Maybe she got pulled off to do something else?" suggested Gisela. Her and Vanessa proceeded to walk backwards and have Heather follow them without issue.

"Doesn't explain the sandal we found or the bull. But I guess one mystery at a time," groaned Vanessa. "Watch your step. Cowpie right behind you," she warned her friend.

"Nice catch," Gisela thanked, stepping over the hazard. "When we find her she's definitely the one cleaning this up. Cause I know I ain't. Got my own shit to do."

Vanessa sighed. "You and I both. Heather is in deep shit if she doesn't have an excuse for this."

'My name Heather!' snorted the happy bull.

They found a clean, empty stall and put the mystery bull in. They put in a bucket of water and feed then went to leave through the side door. They paused to inspect the shit filled rubber overalls and boots that had been left near the door. However both had too much on their minds to investigate another mystery. Heather was momentarily put off by friends leaving. Just to see her food bucket and forget all about them. She was hungry so she ate. It was all the deep reasoning her mind required and could have gone on happily like that forever. Never complaining or thinking she'd lost anything.

But forever turned out to be just another fifteen minutes. Heather was eating, shitting, and pissing freely when her body's vast changes undid themselves. The transformation back into the athlete bombshell she'd been soon a third of the time it did to make a bull out of her. The steamed off her while her bowels and bladders empties themselves completely during the squish back to a normal sized woman. Her limbs flailed and she crashed around the stall during the course of things until she'd eventually came to lay squirming on her back.

As each of her eyes was shrinking and turning human again the brain it was connected to was crashing back into its old self-awareness. Something that bewildered and confused Heather to what was going on around her. All of her old memories came back one at time with recollection triggering more memories and more memories of who she was. Simultaneously coming to grips with a sense of self that was more present that a bull was capable of. She knew she was Heather now, yesterday, tomorrow, and that woman had hopes, regrets, and rationality. Was enough to make the last minutes of the changes go by without any fight from her. Heather merely closed her eyes and waited to feel normal again.

The tingling transformative magic ebbed from her completely and Heather was whole again physically. Opening her eyes and standing back up, her head ached when she tried recalling her recent memories. As they came back to her she saw the barn around her, the stall she was in, and then the shit and piss caked on her from her struggle back to humanity. It was a lot but she breathed easy and didn't mind the smell at all. Was actually calming to her. Which was good given that awareness of herself meant Heather knew her friends were looking for her and she'd disappeared on the job. Turning herself into a bull no less.

The rest of the day for Heather was an exercise in how far she could stretch the truth and cover her own ass. She'd recovered her clothing that her friends had missed since they were under manure piles. This included her phone in his heavy duty case that thankfully survived the mess. There were tons of missed calls and texts of course and it seemed there was nothing she could do to get out of this unless she got creative.

Heather's excuse was that she had been knocked out behind one of the manure collection areas and had only just woken up. It explained most things, including her appearance, confusion, and odd behavior but Laura insisted she'd looked there. It also didn't explain the shit filled overalls but once the farm's owner arrived it wasn't important. Miss Fayebrook listened to Heather's story and made sure she was taken to a hospital right away. She'd been unconscious for long enough to be a concern and not wanting to blow her cover, Heather went along with it. Heather checked out fine but was told to rest for a few days. That was her plan that night but the following morning she left for work like she always did and clocked in on time to many people's surprise.

Insisting that she was fine and that the doctor gave her a clean bill of health no one there was going to argue. The mentality on that farm and others was one where you worked through any pain and got on with it. So they respected that she was back and had no trouble shoveling manure and hay all day. Her friends Vanessa, Gisela, and Laura were the lone few showing concern for how their friend was acting. Not just in her showing up but as the day progressed they noticed their friend not acting like her usual self. Breathing with her mouth open, scratching herself, ogling the heifers, touching herself while ogling heifers, farting, chewing her lunch with her mouth open, telling crude jokes, and doing a bad job of hiding her frequent flatulence. They were concerned about these things but with her normal otherwise. She actually worked harder and never wandered off once. So her friends passed it off to themselves as a side effect of her injury the previous day. In a couple days Heather would be back to usual self in no time.

The next day and things were going well with Heather acting strange like the day before but she was also just as eager to work. The morning went well and when it came time for Laura to assign some individual tasks Heather volunteered to clean up the bull barn again. They thought it was a good sign she wasn't afraid of the place where she'd had the accident. Even saying she'd keep an eye out for the mystery bull that surprised her and gave everyone else the slip. Her sense of humor hid her true intentions.

Once alone in the barn again Heather felt at home for the first time since she'd woken up from her transformation. The mix of smells, the floor, the way it was all lit; it brought out the bull in Heather's brain that had never truly left her. Unlike her body that was wholly human, Heather's consciousness had a bull's nascent instincts as a foundation. What her friends had seen was part of it but Heather had been clever in hiding her bouts of masturbation while on the job. Compared to at her apartment where she walked around nude while eating, shitting, pissing, and masturbating whenever the need arose. She'd cleaned herself up enough both mornings to get by. When Laura offered the barn to clean Heather tried not to sound as excited as she really was.

"There you are, gorgeous," Heather purred when she found the mount. It had been moved back into a storage area the previous day until next week's collection. Her intention had simply been to ogle it but that got her blood pumping so much that she couldn't pull it out and set it up fast enough. "Just one quick little fuck to get this out of my system. Need a proper place to cum," she told herself while securing the unit to its spot in the middle of the barn. This time there were no other bulls watching so she'd have all the pleasure for herself.

She shed her clothing readily and assumed the position with her crotch pressed against the unit while she fucked it with a bull cock. One she could more vividly imagine this time thanks to her previous experience. Leading to another orgasm that reduced Heather to a quivering, grinning mass flopped forward on the mount desperate to catch her breath.

Indulging herself in the same matter that brought on her transformation last time wasn't done without Heather aware what would likely come of it. Sure enough she was sporting a bull cock and some balls big enough to breed a thousand of heifers. While it grew on her Heather wandered from the mount to some hay bales stacked near the back of the barn. Partially to find someplace comfortable to masturbate and play without a hard floor under her. A part of her thought that repeatedly using the enchanted mount is what actually fully changed her. Going one round and keeping away would certainly just return her to normal in a few minutes.

Logic she kept to despite growing a tail and her anus was puckering up like a cow's. The return of manure farts and a foot of bull cock brought pleasure to Heather so she had no reason to think anything amiss. Cramping and aching in her feet showed that the transformation wasn't unfolding the same as last time. A sign that Heather should be seeking help. Her horny notion instead was bending her still flexible legs so she licked and sucked her own toes at the same time they were changing.

'Couldn't do this last time. I was missing out,' was Heather thought to herself as she sucked one deforming after the other. Which got easier when Heather's tongue was helpful enough to begin its growth into the useful bovine tongue. Making it harder to suck but the tongue bathing of the different forming hooves or upper portions of the foot that would be pastern in time. Loving the opportunity to indulge her kinks was enough to ignore her changes that weren't stopping. 'Mmmmm, cow tongues are the best. I love this thing.'

Heather was interrupted tonging between her hooves and balls when she heard voices outside. Listening carefully she can make out that it was her friends Laura, Vanessa, and Gisela talking. It immediately brought back memories of her flatulent close call the day before. Riling Heather up as she rose off her hay bale to hobble over to the large double swing doors. There she could hear her friends clearly on the other side. With yesterday's two successes in staying close but hidden fueling her- to say nothing of her dulled sensibilities from the bull within- Heather unlocked the doors carefully, pushing the one side open until her friends were visible.

Laura and Vanessa were standing close backs turned to Heather with both also holding reins attached to a heifer each. Laura's heifer in particular was blocking line of sight between her friends and Heather. Giving her no reason not to lean there, masturbate, and listen to their less-than-idle chatter.

"Like I said, just give it time. She's young and in good shape. You know her, she's resilient," Vanessa reminded the other two in response to something Gisela said.

"I know. I agree she'll get better. But she should at least be taking two or three days off before coming back here. I'm sure Fayebrook would have paid her part of her salary for the time," Gisila suggested.

"Probably would have. I know right now she's mostly up in arms about that disappearing bull that only you two and Heather saw," Laura told the two. "She had Reed and Carl spend all yesterday searching the whole farm for it. Called neighbors too but nothing. Had to cancel our date the other night too because they were looking."

"Ohhh, now I get it," Vanessa snickered at Laura. Gisela too.

"Huh? Get what?" asked Laura.

"You're just mad because you didn't get your bull dicked boyfriend to bang you like Bessie here," teased Vanessa, tugging her cow's reins.

"Can you blame her? She was gushing like mad during lunch the other day about that date. Mad you might have missed out on sex because of a phantom cow," Gisela joked.

Laura scoffed. "Oh come on! You think I'm that one dimensional? I just missed his-"

She was stopped mid-sentence but a loud, nearby fart with the intensity and stink of a cow's but with the flapping of chunky ass checks punctuating the drawn out note. Startling the three girls who looked to their heifers first but it hadn't come from either. Then when they looked behind them they saw the slightly ajar barn door. A small pile of manure could be seen but no culprit.

"What in the world was that?" gasped Gisela. The stink stinging even her the other's farm conditioned senses. "Don't tell me we got another mystery cow somewhere," she added.

"I'm not sure but I hope not," Laura said as she eyed the scene. "But maybe you should go find your heifer, Gisela, and then come back here. We gotta get these girls moved before lunch. I don't want another one ruined like yesterday."

"Sure. Anything to get away from that smell," Gisela said with a hand of her mouth before hurrying off.

Heather had been so into stroking her cock that when the gas struck her she let it out instantly like any bull would. It proved louder and more solid than she had been planning. She had barely enough time to duck back inside to avoid being caught but her heart was racing as she stumbled away from the door. The first couple steps were on two legs but in need of haste and comfort Heather dropped to all fours. Once there and far enough from the door Heather's body longed for proper release again. Meaning her sights fell on the mount and her body was en route.

The distance she gradually covered saw her changes accelerating to outpace her previous changes physically. This while the mental adjustments brought Heather's intelligence and desires back down to the bull's level. Doing so with her full compliance and willing submission to whatever this magic had to do to make her big again. Her hands, limbs, and torso were constantly bloating and bulging with all the bull that Heather had been. Feeling the heaviness of her horns or the view down a snout meant she was closer to being able to unleash her lusts properly. Just as pushing out more manure and lurid reinforced she truly was a bull.

"Need, fuck... me big bull," went Heather's final, barely understandable words. She grunted as she mounted the Milking Machine- her 1,000+ pound body three quarters through its full transformation. But it was close enough to working for Heather to crawl up on the mount to claim her favorite prize again.

It's to this scene of Heather submitting to her bullish desires that Laura, Vanessa, Gisela, and their three cows walk in on. At first they don't know what they're seeing and are speechless. That the thing they saw was Heather, their Heather, took another few seconds of staring at the thing's meld of bovine and human facial features. Leading to shocked screams from all three.

"That's Heather? How is that, like, I don't even know!" Gisela shouted.

Laura meanwhile ran in front of the mount desperately trying to get Heather's attention. "Heather! Hey! Stop! Look at yourself!" yelled Laura trying to get some sense into Heather.

"She's just going to town on that thing! Fucking hell, Heather! This isn't you!" Vanessa pleaded.

But Heather's only answer was to snort and thrust faster. Unfortunately her transformation was causing her bull cock to fall out and when she couldn't reinsert quickly enough actually jumped down from the mount. It was out of frustration but her friends took it as a sign they were getting through.

"Okay, I'm going to go get some help. You two stay here and, I don't know, keep an eye on her!" Laura told them as she took off running.

"Wait! I'm coming with you!" a frightened Gisela yelled. "I can't watch that! I can't!"

Vanessa stood there alone with Heather unsure what to do or say. She could only fret and watch Heather's transformation finish with her the spitting image of the mystery bull she'd seen with Gisela the day before. Answering that question while raising a myriad of new ones. Vanessa was running through some when Heather the bull came to its senses with her erection and needed to breed unsatisfied.

Seeing the bull's head turn its head in her direction made Vanessa very nervous. "H-Heather?" she asked shyly. When Heather started moving in her direction Vanessa backed up slowly fearing for her life. "You still in there, Heather? Please tell me you are..." Vanessa prayed under her breath.

'Me Heather,' the bull dimly thought as it approached. Its nostrils flaring and sniffing a sexy smell it simply had to taste.

Some minutes later Laura and Gisela return along with farm owner Miss Fayebrook and several of the senior ranch hands. What they found was Heather mounting one of the heifers.

"She's already fucked the other two. I tried to stop her but look at her! All I could do was make sure she didn't hurt herself or any of the cows," Vanessa explained of the situation.

Several of the ranch hands, Reed among them, helped calm and comfort the girls as Miss Fayebrook assessed the situation. A shrewd, silver haired woman of advancing years but with no drop in acumen or energy. It was certainly telling to the three friends that her and the other senior ranch hands were not showing the same level of shock as they had to what had transpired. Fayebrook whispered some things to the workers, sending all but Reed off on some task. Closing the barn doors, pushing the mount back to storage, rounding up all the cows, Heather included, and finding them stalls once the bull had finished breeding the third of the heifers. Leaving the three friends with Fayebrook and Reed, who was still calming Laura down from her panic.

"What is it, Miss Fayebrook? What happened to Heather? Can you fix her?" Vanessa asked her boss.

"Please say you can fix our friend," added a hopeful Laura.

"Ladies, I'm sorry but your friend, my employee, Heather, isn't going to be leaving the farm now or ever. If she'd only fooled with the machine once and said something we could have kept her away. There's no turning her back from what she is. Sorry that I don't have better news," revealed Fayebrook solemnly. "That piece of equipment is... unique. Effects that help a bull, a real bull, perform at his best when we're collecting have quite the different outcome when a human uses it. I'd always assumed only men could fall prey to its 'charms' so I always oversaw sessions and assigned women to clean the barn. Heather must have been quite persistent."

Laura broke down while Vanessa and Gisela couldn't believe what they were hearing. It would take more explanation and time for it to really sink in. Accepting it wasn't easy for any of them but it got easier with time. Three other bulls on the farm had similar origins and of them Heather was the biggest, most virile, and could have fertilized a field by himself. Seeing their friend living as a happy and content bull day in and day out helped a lot.

For Heather it was a blissfully simple new existence. She acted as naturally as any cow would and was always happy to see any of her friends when they came by. Heather also had a reputation of preferring to mount heifers when workers or any person was around. The only issues arose any time Reed was around when Heather would purposely lift her back leg to show off her big bull genitals. As if she was trying to show the man what it meant to be hung like a bull.
