This story contains nudity, course language and sex scene. You have been warned!

Hannah presses her password into the screen in order for her to allow her to get inside. At twenty-five years old with shoulder length brown hair with the bluest eyes, Hannah had a well shaped body and looks like a goddess but despite the her many 'achievements' the one she was most glad and fond about as working with the great mind of Professor Charlie Fisher. Opening the door to the secure laboratory, Hannah makes her way down a corridor and to one of the rooms to find Charlie already at work with her other co-worker Cindy with him.
"Good morning!" Hannah said.
"Morning" Cindy replied while Charlie said nothing as stayed with his work.
"Still his talkative self as usual!" Hannah mumbled underneath her breath as she grabs her lab coat and went straight to work as well. Hannah was glad to work with Charlie the problem was she wished she knew what they were exactly working on, so far she could put together it had to something to do genetics it was beyond top secret as Charlie was the only one that knew, but Hannah kept to her work despite the clueless of what she was exactly trying to do. As the hours past and Hannah was busy working on the computer constructing some certificated DNA strand which was bit weird looking even for her.
"Miss Grander," Charlie said walking up to her, "I need to take a phone call… make sure my work area is untouched!"
"Will do Professor Fisher!" Hannah said watching him leave the room and as the moment he left, Hannah makes her way to his work area to have a clearer idea what she was trying to do only to be even more confused.
"What are you doing?" Cindy asks walking to Hannah.
"Just seeing what Charlie is working on!" Hannah said as the two women knew to steer clear from Charlie work area but with him now out of the room, the girl's just help but to snoop around. As Hannah looks through some paper work seeing that her theory on that it was something to do with genetics was correct as to the paper work, they were working on some sort of bovine enhancement.
"Hey what's this?" Cindy asks causing Hannah to turn to see Cindy holding a sealed canister filled with some strange liquid.
"No idea but you might to put it back!" Hannah said, Cindy nodded her head in agreement and was about to put it back.
"WHAT ARE YOU DOING?!" a voice called out causing the two instantly look up, Cindy freezing up on seeing Charlie having walking in the room and seeing them with their hand in the cookie jar she drops the canister to the ground causing it to break. Hearing her mistake break, Cindy looks down to see the strange liquid not splash everywhere but instantly go in air born spreading across the room. The two girl's cough as the strange fumes made them feel like they weren't getting enough air. Hearing a loud buzz sound the strange fumes got sucked into the air vents leaving the three standing their.
"You fools, you have any idea what you have done?" Charlie yelled as he makes his way to the two Women but stop as he reaches down to his crotch area.
"Ah!" Cindy cries out finding she was doing the same thing with Hannah shortly behind her. Three just moan in pain as the two Women noticing that a bulge was starting to grow right in the crotch area. Getting scared Hannah and Cindy pull off their pants to find that bulge was growing just above their crotch area and filling out slowly.
"Uh" Charlie moans causing the two Women to look up and gaps in shock to see Charlie having his cock out with one hand around it, it looked be growing in size and in length causing the two Women to wonder what was happening to all three of them. Pulling down their panties as the fabric was being pushed against this unknown bulge, it slowly lay gently on top of their vaginas as four bumps grew on it and push outwards. With it now the size of a basketball, the four bumps continue to grow three inches long and an inch thick making the two Women realize that they had grown an udder.
"What's happening to us?" Hannah cried out finally breaking the silence.
"Our work… that's what happening to us!" Charlie snarls as his cock looked like long bread roll while his balls now the size of tennis balls hang between his legs. Cindy noticing that their changes had seem to stopped, removed her pants and undies off with great difficulty as with each time she moved her legs she bump her udder causing the liquid inside it to slush area making her terrified even more.
"Is it over?" Hannah asks.
"By how much we inhaled I strongly doubt it," Charlie snarls "Congratulation, you are a now about to witness our lives work at its best!" and with that Charlie walked away out of the room.
"Wait exactly how much more is going to happen to us?" Hannah asks turning to Cindy and got the shock of her life to see her completely naked.
"I don't know but I think you might want to get rid of your clothing encase it does go far further!" Cindy told her, Hannah was too shocked of seeing Cindy standing there completely naked after all she did notice that she was a good looking girl like her self with her long dirty blonde hair, green eyes and a rack that was large and firm with a body almost like Hannah's with the exception of that she had much of a wider hips then she did. Sheepishly Hannah removed the rest of her clothing catching Cindy catching her out at couple of times. With the two Women now naked, Cindy made her way out making Hannah notice a small bump above Cindy's butt, quickly looking back to her own, Hannah didn't see one but she did notice that her arse had slightly grown in size as did her upper legs. Following Cindy the two soon found discovered that entire lab was under quarantine meaning that all doors and window to get outside was completely looked making escape impossible, as the two continue to walk around the two easily could hear the slushing of the liquid in their udders as they took a step making them quite uneasy. Soon finding Charlie in the flouriest area on where others had grown all kinds of grass, fruits and vegetables.
"What are you doing in here?" Cindy asks causing Charlie to turn but get the shock of his life two she Cindy and Hannah completely naked, Cindy showing her entire self off while Hannah covered her breasts and blushed when Charlie stared.
"What… why are you two naked?" Charlie asks.
"You said it might get worse so we got ready for it!" Cindy said, Hannah just gave her bit of a look wondering if she noticed the numb on top of her arse had grown longer and now growing hair at the tip of it and even Charlie look to gone through some changes too, with him having more weight on him plus the two small bumps on his forehead.
"I said I doubt we have stop I didn't say we will!" Charlie explained.
"Then why are you in here?" Hannah asks
"Just encase it does get worse and by your changes it is!" Charlie said, Hannah quickly looks down at her self to see anything was still the same since the last time she checked.
"What do you mean, I haven't!" Hannah explained.
"Oh please I don't think your ears weren't that long!" Charlie said, instantly Hannah reached up to her ears to feel that they have indeed grown longer so much that they could be seen through her hair.
"Yeah also your nose is wider, you put on some weight in arse and…" Cindy said as she pauses to look behind Hannah, "Ooh, look a tail!"
"What?" Hannah screams spinning around to see the start of a tail growing from her backside.
"Still we must prepare for what is coming!" Charlie said
"What is coming? We are turning into cows, that what's happening to us!" Hannah yells. "We must find a way to stop this!"
"How, by all means do tell us how to reverse this, this wasn't meant for humans so that changes my be permanent, so If I was you I might get use to of walking on all fours!" Charlie told her.
"You are such an asshole!" Hannah snarls.
"Okay you two, back in your corners!" Cindy said "we must prepare for the worse but that doesn't mean we don't have to give up, if there's a way to change us, there's a way to reverse it!"
"Good luck with that!" Charlie growls.
"Come on Hannah" Cindy said walking out of the room with Hannah shortly behind her.
"You really think we can reverse this?" Hannah asks.
"Yeah why not, we helped him make this thing we can reverse it!" Cindy said as Hannah felt confident of reversing the changes. Back in the laboratory, the two women discuss on what to do and work separately to increase work effort. As time went on, Hannah found that her tail had fully grown and now can move it side-to-side with the most ease, she also found some stiffness in her fingers, her udder now bigger then before lay over her widen legs and was probing her to ease the building pressure with inside it, Hannah also notice that her waist has widen too as her frame use to fit on her seat well while now it was a tight fit.
"God damn this thing," Hannah mumbles to her self as her udder was one major distraction leaving her no choice but to relive the pressure. Grabbing on to one of the teats, Hannah began to squeeze it, as she begins to milk herself a squirt of white liquid shot giving Hannah a hit of pleasure like she never felt before. Now pumping the teat, Hannah just sat in her seat puffing in pleasure as more and more squirt of milk shot out of her, Hannah couldn't believe how good this felt as attempt to gain some self control, forcing herself to stop.
"Hannah, can you come here please?" Cindy asks her voice sounding like it was trembling, curious Hannah gets up and makes her way to Cindy. First thing Hannah notice was how she walked with the udder as her hips much wider now, it was more waddling then anything else plus she also notice she was standing on her tippee-toes for some reason.
"Yeah Cindy, what can I do you f-" Hannah paused in mid sentence of seeing Cindy, first her nose was much wider and darker in tone, her ears poke out of her head making then extremely visible through her hair, she had put on some weight on as her waist looks wider then Hannah's was, Cindy's udder was the same size as Hannah but the one thing that scared Hannah was the hooves on Cindy's hands.
"I've got hooves!" Cindy sobbed as a tear runs down her seeming more bloated face.
"Oh god it is getting worse!" Hannah said as she could of gotten that from her own changes.
"I… I need your help… I… I… I need you to… milk me!" Cindy said.
"What?"
"I can't milk myself, please… you got to do it for me!" Cindy pleaded, Hannah knew if she was in the predicament Cindy would do it for her, so Hannah bent over and began to milk Cindy. As milk shot out of Cindy's teats, Cindy began to moan in relief and pleasure which Hannah was caught of guard as a bit of it sounded a lot like a cow mooing, keeping this up for a minute or two as her fingers were just getting too sore and stiff to do anymore.
"I'm sorry, that all I can do!" Hannah said.
"It's okay!" Cindy said looking down at Hannah's feet. "Oh no Han, your feet!"
"Oh please don't tell me!" Hannah said looking past her udder to see that her toes were now were hooves. Hannah couldn't believe it the two were becoming more and more like cows as time went by.
"Hannah I don't think we be able to find a cure!" Cindy said sounding defeated.
"Don't say that we moooost!" Hannah said instantly placing her hands over her mouth on what she just did.
"Hannah… you… you mooed!" Cindy said pointing with her hoof.
"Oh god, how mmmmmooouch will we changed?" Hannah asks as she starts to cry finding it hard not to moo with any word that began with the letter 'M'.
"I don't know" Cindy said as she sat up but instantly fly forward, crying in pain.
"Cindy what's wrong?" Hannah asks.
"My back, my hips they hurt!" Cindy sob loudly. Hannah instantly made her way to the back of Cindy to see what was happening, her hips were widening, much further causing her legs to be a foot apart by the knee causing her udder to hung between her bloated legs, but what shocked Hannah was catching Cindy's vagina now much larger then before and sticking right behind her.
"What.. What is it?" Cindy asks as the pain seems to deplete.
"You… you have a cow's vagina!" Hannah said.
"WHAT?" Cindy screamed as she pushes her self off the table but found herself falling to her all fours.
"Oh god!" Hannah whispers.
"I… I can't get up, I… I'm stuck like this!" Cindy sobbed.
"Cindy you look mmmoooooore like a cow!" Hannah explained.
"Well I don't to add more fuel to the fire," Cindy said through her tear as Hannah made her way in front of Cindy. "You are shortly behind me!"
Hannah looked down to her hand completely forgetting all about them, as looks to see that they were hooves just like her feet.
"Cindy I'mmmmmoooo scared!" Hannah said.
"Me too!" Cindy said.
It wasn't until another fifteen minutes until Hannah joined the quadruped family, by then Hannah found that she couldn't say a single word without mooing, plus her arms were much longer then before, while from belly down she was a full bovine. As for Cindy, had just lost her breasts by her chest expending out, she was more in her progress then Hannah having her face and neck the only last features of her once human life still remaining as she found that like Hannah, found it impossible of not mooing when using words with 'M' in it.
"Cidmoooo I'moo moorry!" Hannah mooed as her face had kind of pushed out.
"For what?" Cindy asks.
"Ifmoo Iooo did moot gmoo mear Charmoo's moork moolace, moois mooouldn't happemoo!" Hannah explained trying to say by not going to Charlie's work place they would still be human.
"It okay Hannah, I'mooo sorry too!" Cindy said. Hannah lowered her head watching her breast get swallowed up by her chest, Hannah turns back to Cindy to see her neck growing longer and thinker.
"Moo… ook mute moo!" Hannah mooed finding her teeth becoming larger her mouth as did her tongue as her face continues to push out.
"Moooo mtooo!" Cindy finding herself unable to speak without mooing. As the two go through the last changes letting them let out a horrified moo as they last human features left them. Leaving the two women as nothing more than fat bovine.
'Oh god look at me, I'm disgusting' Hannah thought turning to Cindy finding that her coat of fur now just growing over her body, Hannah figured that same thing be the same for her as she feel a tingle running over her entire body. Taking couple steps, Hannah found it scary and disturbing of walking on four legs but most of all having her udder slap against her legs as it once again scream to be milked once more. Catching a sent, Hannah sniffed the air as the sent was strange to her as it was moist and cause her vagina to become wet.
'What is that smell?' Hannah thought hearing someone entering into the room, turning her large head to see a pure black bull standing there, breathing heavily.
'Wait is that… Charlie?' Hannah asks as she, Cindy and Charlie were the only ones affected and since he was the only male meant that this bull was indeed Charlie. The moist smell was much stronger and it was coming from Charlie, Hannah just stood there as he makes his way to behind her.
'Wait, what is he thinking?' Hannah asks as she could feel Charlie's cold nose on her Vagina's lips causing her body to shudder, hearing a moo coming from Cindy, Hannah began to wonder why as turns back to Charlie to get the scare of her life, his bull penis was a full erection as semen slowly drips from it.
'He's not think…' Hannah didn't even finish her thought as Charlie jumps on top of her. Hannah's mind screamed in horror as she tries to move herself from Charlie but his massive weight pinned her down.
'Charlie please, no don't!' Hannah pleaded mentally as penetration hits Hannah. Hannah eyes widen as Charlie forces his penis straight into her causing her body to rock in pleasure and fear.
'No, no, Charlie… oh god… oh' Hannah screamed in her mind as Charlie thrusts himself into her causing pleasure to over flow her mind, Hannah wanted this to stop, she wanted to gain control over her body but with no luck was with a one more thrust Hannah came just as Charlie did over flowing her with his semen. Hannah's body shook in pleasure and fear as Charlie dismounts her catching another scent, Cindy's…

It wasn't until a group in hazmat suits entered into the lab and did they get the shock of their lives when they found two cows and bull and not Hannah Grander, Cindy Block and Professor Charlie Fisher. It wasn't until a week after that they realized that the cows and the bull were in fact the three as the DNA showed some characteristics of their human DNA, they also found Hannah and Cindy pregnant and had kept their human intelligence while Charlie was nothing but a animal, the three were move to a isolated milk farm where they were taking care of and had their calves as time went by. Scientist went through Charlie's work to find no way of how he made the formula or any way to reverse it, therefore placing the experiment marked as 'A successful failure'!
