Experimental Transformation (Cow TF Story) (Patreon)

PART 1

You seem such a lovely young lady. Are you sure you want to consider this experiment? The results could be… devastating.” The rather unkempt scientist frowned as he observed his young, amber-haired client. The girl had contacted him a day or two ago in response to an ad he’d run on a social media site asking for applicants to participate in a study on the malleability of the human body. “I’ve never been happy with how I look,” she murmured. “I want to be… something different… something… exciting.” “I cannot guarantee that what will come of this will make you look like something from your dreams, madam,” he replied a touch stiffly. “The chemical infusion that I have might not affect your physical appearance at all… or it might make you into something… very strange… remember, this is not a proven formula yet. We have some expectations of how it should work, given that we’ve modeled the results extensively. But what actually happens when it is injected into you... well… that’s what we are aiming to find out. Yes, we will pay you a hundred thousand dollars for compensation, but that’s the limit of our liability to you. When you sign our waiver, you will be signing away your right to sue for damages if something goes… awry.” “I don’t care about the money or the liability,” she replied somewhat sharply. “My purpose is to be… changed… my life as it stands now is totally boring and so anything that you do will at least give me some gratification at the very least.”

The scientist almost called off the whole thing at this moment. This client’s mental state seemed… precarious in the extreme and he worried about how that might affect the outcome of his experiment. Then again, he also recognized two important details: First, it was exactly this kind of person that his experiments had been designed for. People who disliked their own appearance so much that they would want to pay a rather large fee to be altered… made into someone else… his hope was that the elixir would transform the client into a more beautiful version of themselves and thereby improve their self-image. This client seemed so… broken… image-wise that he wondered. But.. the second fact was far more telling from his own perspective… hers was the only reply he’d gotten. Alright… I’ll send my female assistant in and she will prepare you for the injection. Do be aware that you will be continuously under observation and the entire sequence will be recorded. You’ve already acknowledged that you are comfortable with that in the waiver you signed, but I just wanted to remind you.” “I don’t mind, she replied shortly. He left the room and a female wearing a white lab coat replaced him. She undressed and then took a moment to observe herself in the full-length mirror on the wall nearby. She didn’t particularly like what she saw… a slightly hefty figure with a nice, full bosom, but a little belly that she absolutely hated. Soft, attractive green eyes, a rather boring reddish-gold hair that hung a bit limply to her shoulders. ‘It’s gonna be better…’ she thought to herself. “It has… to.. be… better…

PART 2

“Hold still, now, this is going to sting a bit,” the assistant pressed a hypodermic against her side and pushed. Amber winced a bit, but held still as instructed. Almost as soon as the girl withdrew the needle, she began to feel a strange sensation that started at the spot where the injection had been made and rapidly spread out from there. A wave of dizziness and a blurring of her vision. “You might want to sit down, said the assistant. This is a powerful steroidal compound and it might make you feel a little unbalanced.”
“A little,” she agreed… “No… a lot!”
She did slump down in a chair next to the examining table the sense of vertigo increased until she wasn’t sure where up and down actually were, then, as quickly as it started, it faded away. “You are already reacting… transforming…” the girl’s eyes widened. “It’s strange…”
Frightened, Amber sat up and inspected the mirror again. What she saw was downright alarming. Her nose had widened and good grief, were those !!horns!! growing our of her hair?? Her ears had also changed dramatically in just these first few minutes, opening like flaps from the sides of her skull. “I’m starting to look like a damn cow!” She yelled… where is that freakin’ so-called scientist!??! Get him in here, now!”
The door opened a moment later in the scientist strode in. “Calm yourself,” he said with a placating gesture of his hands. “The process has just begun. You may morph through several iterations of yourself before it finally completes.”
“I didn’t sign up to be turned into a damn heifer!” She shrieked. “You said I’d be more… beautiful… this… isn’t… pretty!”
“I… ahhhh… I never said I could exactly predict how the elixir might affect you,” he stammered. “Our preliminary tests with animal subjects indicated that the results would remain in the same species and genus as the subject started from. Your reaction is… unexpected. We ran a DNA scan on you, as you know, when you first came in and it certainly didn’t show up any bovine traits! Please calm down and let us investigate what’s happening here. We need to learn.” This guy was sweating bullets right now. She might have signed a waiver, but he could already here some ambulance-chasing lawyer demanding payments that would strip him of every dime he had and might ever make for the rest of his life! There was no antidote for this stuff… nor was it even certain at this point if the transformation might be permanent, or if it might… revert back after some time. Several of the animals tested had indeed reverted back to their original forms after a few hours. One had seemed to gain the ability to morph back and forth between two forms at will. Unfortunately, the shocks to the systems of these lower creatures had proven too much and all of them had died shortly after being injected. His theory… as yet unproven and untested, had been that it was pure shock at the changing that had overloaded the nervous systems of the test animals. Something with more… resilience… was needed to prove the viability of his formula. So, he had quietly falsified a considerable amount of his test data and submitted an application for human testing… and held his breath. As he’d hoped, some government functionary had read this pack of lies and bought it, hook line and sinker. He had been completely amazed when the approval paperwork had arrived a couple of weeks ago. Almost immediately… certainly before anyone had a chance to really read his paperwork and react to it… he had sent out ads hoping to attract a human subject. Now, he had one… and unfortunately, she was indeed starting to look like Elsie the Cow from the milk container in the refrigerator. But there was something else… there was more to this than just her outward appearance… she was also developing… a kind of… feral power… he felt a strange stirring as he looked her over. Test data was still flowing full speed into his monitors and her heart rate and blood pressure were about through the roof. Not surprising considering how angry she was. Her eye color had changed, too. Shifting from green to a darker brown. So far, the alterations had not affected her body shape, size, hair color or her healthy bustline. His mind attempted to process what his eyes were seeing. Actually, she did seem more attractive as a cow, although he was pretty certain she wouldn’t agree with that…

PART 3

The transformation continued. Now her skin tone began to lighten and get… a little fur on its surface. Blotches of darker color fur appeared here and there on her arms, abdomen and legs. Was indeed becoming a heifer. Though really not a bad looking one. Her core body retained its shapely figure. Her bust remained big… perhaps even grew a bit. Her face was the biggest change. It lost most of its human female characteristics and took on a look far more cow-like. She kept looking at herself and then back at him… “Is this… permanent?” She asked in a horrified tone of voice. “I… ah… don’t know.” He replied hesitantly. “Some of the test animals… reverted after a few hours. The problem we encountered was that each iteration of the transformation requires a lot of energy. You have to have the stamina to complete the process, otherwise… it could be fatal.”
“Oh, you are just making this sooo wonderful!” She snarled. She reached for him as if to strangle him and at first, he backed up. Then… it seemed as if a powerful attraction came over him as her hands got closer. He wanted her to touch him… “I… ahhhmm… oooh… strange…” A sense of longing and desire washed over him like a wave. She seemed to lose her angry stance, too. Her glare was replaced with a look that was… far more attractive… almost… nervous… as if she wanted something… as if she wanted… him. “Don’t run…” she said softly. “I need you… you have to explain to me what’s happening to me… please… don’t leave me like this…”
“I have no intention of abandoning you,” he replied. “The effects happening here are entirely unexpected. It certainly is happening because you are a thinking, reasoning human and not an animal operating on its instincts.” Amber stepped closer to him and her hands slipped around his shoulders, slowly… hesitantly… as if touching a human male for the first time in her life. Her mousy, red hair was lengthening even as she closed the remaining distance between them and began to caress his body with hers. It got redder, too as it lengthened. Suddenly, she leaned into him and kissed him… the caressing warmth of her tongue provided the detail that she had a cow’s tongue, now. Larger by far… softer… a fine, silky and surprisingly tasty kiss followed. “I want you,” she murmured into his ear. “We need to mate.”
“Yes… yes… we do…” He replied… Part of his mind instantly rebelled at the thought of coupling with his… subject. So… unprofessional! Part of him, however, was entranced with the scent of her body. The softness of her pelt, her feet had morphed into hooves, but she retained her human hands. Her pelt… it could no longer truly be called skin, gained more mottling and continued to lighten towards a creamy white base.
“We can use the exam table,” she suggested softly. “Strip down… I think I want you on me… now…” She was almost hypnotic in her entreaty. And he went with her. As he completed removing his clothing, there was a horrified gasp on the other side of the room and the clatter of a clipboard and pen hitting the floor. “Miss Roberts, the scientist said quietly. “Please leave the room if you are uncomfortable with observing what’s about to happen between us. Do not leave the building for now. Please remain near the intercom in case I need to speak with you.”
“Yeh… yeh… yes sir,” she stammered and banged out the door, slamming closed behind her.
His eyes returned to hers… so large, now and soft… beguiling in the extreme. “Come to me now and let’s see what happens when we… encounter each other…”

PART 4

She lay back on the examination table and opened to him… A fragrance hit him in face like a ton of bricks. A scent that drove him… made him… desire her… need her touch. His opinion of her now had changed fully along with her transformation. She was… beautiful… to him… he desired her… And now… he was going to have her. Her fingers gently played with his maleness and then she took him and guided him into her. She closed those beautiful brown eyes and sighed in pleasure when he took over and pushed deeper into her. “Oh that’s lovely, doctor,” she murmured.
“It’s Ron,” he said softly in reply. “I think under the circumstances, we can have a first-name relationship with each other, Amber.”
“Yes,” she said softly. “Come on… make me yours!”
When he pushed into her, it felt like nothing he’d ever encountered before. She was incredibly soft and wet and yet… every thrust into her seemed to… affect him in a strange way. Every push… felt stronger… more determined than the last one. “Mmmmm… good draw,” she murmured as he backed up and pushed in again… They got a rhythm… it seemed perfect and as the moments passed. He began to feel… different. Somehow stronger and more powerful. “Damn… do you realize what’s happening?” Her eyes grew wide.
“What?” He was puzzled.
“You,” she gasped and smiled… “Are turning into a prize bull stud right before my eyes!”
“What?!??!?” He almost screamed and then he turned and looked in that mirror and what it reflected back was beyond belief! He had lost his human appearance almost completely. Become a dark brown male bull. Grown horns larger and more wickedly curved than hers. His chest had expanded and his hips had shrunk to a more shapely, muscular curve. One that fit his hungry partner perfectly. She squirmed under him as he started to pull out, wrapped her legs around his back and held him in her tight. “No!” “Don’t you dare pull out of me this soon!”
He instantly reverted his full attention back to her… He could feel the strength of his new, stud form coursing through every muscle in his body. But he wanted to give it all to her… all to his little red-haired heifer. She excited him in ways that were hard to imagine. Her body was magnificent! Her coloring… breathtaking! Her warm, large udders… delightful! The sensation of being in her… beyond belief! He concentrated on being her perfect stud… satisfying her need to mate… driving her hard… over the next hour their intense loving reached a peak and then slowly eased down to warm, sensual, playful cuddling. They rubbed and found complete delight in each other… she proved that she really wasn’t all that prudish after all…

PART 5

Woah, what a view Amber! You are one… beautiful heifer!” Ron was on his back and his lady subject was riding him hard… slowly… but very, very deep… her body had completed its transformation. Fine, white hair coated her like an ermine blanket, broken here and there with darker markings. Her hips were nice and big and her buttocks firm and smooth. Her breasts were full and shapely and that wave of deep red hair now set off the color of her pelt in an amazing way. Her face was transformed. She seemed to have gotten over the panic of the changes as she’d found that she could not only attract a partner looking like this, but could change… him… as well… on the fly! The act of mounting her had turned him into a bull stud of beautiful strength and stamina. She was now leading the experiment! “Listen,” she said to Ron. “We need to find out if I’ve changed you permanently or if the change will wear off once we… stop this… although… I really don’t wanna stop. You feel so good! I just want more!” “You can have more,” he replied. “All you want, I’ll never say no to you Amber.” His hand reached up and soothingly rubbed her back. She shifted around on him, enjoying the additional pleasure of his rubbing her while she swallowed him deep into her love. She worked him slowly in and out… letting him enjoy the full view of his powerful manhood pushing deep into her velvet caress and back again. “We also need to find out if your… talent will affect anyone you have intercourse with or whether it is just us that gets this going. Miss Roberts… are you still with us?” he asked into the air. “Ahhh… errr… yes sir,” came the reply back over the intercom. “Please ask Charles and Carl to come in and prepare to be part of the experiment… and I want you, too, if you are willing. You had said you would volunteer. I don’t intend to inject anyone else with the elixir other than Amber, but I want all three of you to interact with her to see how physical contact with her affects you.

PART 6

A moment later, the door opened and two men and the lady Amber had seen earlier came in. Ron got off her… it did seem that his movement to get up was somewhat reluctant. But he moved away and put his lab coat on rather than stand there buck naked… which Amber thought… she’d rather see any day!
“You two males flip a coin or something,” he commanded. The winner gets to mount her first.” Both men looked a little stunned… “But… ahhhh… sir…” one of them said. “She’s ahhhh, ahh cow sir,”
“Yes, and you’re gonna love how it feels when she gets you into her,” he admonished them.
“Really? Oh wow,” The other one said… “Okay Charlie, rock, paper, scissors; best two out of three.”
They started slapping hands and Charlie won. He seemed a bit nervous as he stripped down and then climbed up on the table with Amber. She stretched him out and then turned her back on him and settled him into her… That slow, sensual rub started again and Charlie got the most blissful look on his face imaginable. “Damn, she’s… incredible…” he said softly. The other three watched in wonder as he changed before their eyes! His chest expanded, his hips narrowed, his biceps bulged nicely and then his thighs did, too. Like Ron before him, his skin color darkened to deep brown and a soft coating of light fuzz appeared on his skin. “Damn Miss Amber… you’re good!”
“Yer not bad yerself Charlie, she murmured. Keep nice and hard for me, big guy!”
“Oh yes ma’am!” he replied with a sigh of pleasure.
It didn’t take long. Within minutes of them starting, the transformation was complete. Two of the men in the room were now bull males.
“Miss Roberts… are you willing to… perform some sexual pleasuring with Amber?”
“Do you think I’ll turn into something… like her?” She looked askance first at Amber, then at the bull the scientist had become.
“I’ll be honest, I have no idea what might happen. Could be anything from nothing to you becoming a cow like her or… maybe even… something else. The only way we will know is if you will try with her.”
Sanja Roberts had never thought of herself as a coward, but this was a lot to think about. Then everyone got another surprise. Before their very eyes. The scientist, Ron, began to revert back to his normal, human appearance. It took about ten minutes and then he was fully human again. Charlie slipped out of Amber’s lap and made room. Sanja swallowed once and stripped down. She was far slimmer than Amber and even more so with Amber in cow form. But the two of them cuddled together… awkwardly at first, then with increasing confidence as they rubbed and played on each other.
Absolutely nothing at all happened. Except that both girls had a nice climax with each other after about fifteen minutes of play. “Isn’t that curious,” Ron looked up from his note pad and shrugged. “It seems that if Amber wants a mate, she can create a male that pleases her almost instantly… but female to female doesn’t seem to work. “Carl, you are our check for this… mount her and see if she can transform you now, having had time with Miss Roberts in between you and Charlie….”

PART 7

“Oooh… mmmph… damn, that’s nice!” Carl gasped as Amber settled on him and started rubbing him into her. The smooth wet ride made him crazy with desire and within a few minutes, he too, was the bull stud, ready to service the heifer who had become every man’s queen. They continued their play for some time while Ron frantically scribbled notes on his pad and typed into his computer at an almost maniacal pace. “Well… evidence seems to indicate that when a female is injected directly, she gets either a permanent transformation or a much longer-lasting one. With that ability comes her ability to change a human male into a mate of her same type in order to be more… satisfying to her. Female to female intercourse seems to be unaffected and the transformed males revert fairly quickly back to their original forms. Now the question is… will Amber change back or is there some agency that might speed that process up?”
“Now just what do you mean by that?” Amber frowned at him. “My preliminary computer models seemed to indicate that if unchanged male semen enters your mouth Amber, a process might happen that will change you back.”
“Well wait a moment here,” Amber held out a hand in a stopping gesture. “Let’s think this all the way out. First, every test we now perform with these males will be tainted because all three of you have been with me and have been transformed by me. There’s no… virgin… as it were… male to see if that stunt will work. Second, I’m not sure I want to change back. I kinda am beginning to like looking like this.. I’ve certainly gotten better sex than I ever got before I changed!”
That caused all three men to blush.
“I understand how you might decide you enjoy your current state,” Ron replied gravely, but it would be good knowledge to have if we could be certain that the process Is reversable. If you want, once we’re certain, I can inject you again to change you back or… we might even be able to work out an oral method in the form of a pill or a liquid like cough syrup that you could use to transform whenever you wish. That would be an ideal solution.”
“Well, alright, I see you point with that,” Amber looked a little sad… Okay, how do we get around the fact that all of you have had intimacy with me? After all, you injected me with untainted seed when you first mounted me and you still changed and I didn’t change.”
“That can become part of the testing protocol,” Ron replied. You take your pick and one of us will offer you himself orally. I believe it is the oral aspect that will change the formula. Going through your gut and being digested may make a difference. Again, the only way we’ll know is to try it.”
“Alright gentlemen,” she grinned “I’m thinking of a number between one and a hundred. Closest to it without going over gets to give me a mouthful of his love!”
“23,” said Ron promptly.
“30,” said Charlie.
“49” said Carl.
“Carl, my handsome pet. C’mere and give your Amber your best shot hunny.” She grinned and winked at him….

PART 8

“Lucky ba*+ard!” Charlie watched with an envious look on his face as Carl lay down and Amber settled with him. Her mouth opened a bit and caressed the tip of his sex and everyone smiled as his member swelled in eager response to her gentle ministrations. “Oh lord, her tongue is incredible,” Carl moaned softly. “Mmmmm… oh… my… god… that’s… amazing…” He closed his eyes and just got bigger and bigger in her mouth. She kept at him for quite a long time, but she actually gave him a teasing for the ages; suckling him lightly until he was about to explode and then kissing the tip and letting him down. It was the most exquisite of torture imaginable. She worked him through a blue-balls blow job that nearly made the other two men in the room crazy with desire to be part of it, too! Finally, she took him over the top and he spurted cream into her mouth… she didn’t fight it. For someone who claimed she’d not gotten much sex in her life, she seemed… amazingly experienced. She licked him clean as if he was the best of lollypops and then winked at him. And then they waited…

PART 9

Sure enough, over the next hour the fur withdrew and the mottled markings began to fade… it took a while, but eventually Amber was restored to her normal self. She studied her body, back in its original form and coloring again and frowned. “Where do you suppose the cow aspects came from? Surely you don’t expect me to believe there’s some kind of bovine aspect in my… makeup?” “You know, I have a feeling it may have something to do with your self-image,” Ron replied. “You feel yourself as being overweight and not particularly pretty and so… moo.” “That’s really an interesting thought, though, isn’t it?” She replied. “If it’s true… with a shot of that stuff and the right attitude, I could become… anything… any… little… thing… I wanted to be.” “I don’t know for certain,” he replied. “But I think it might be possible.” “Let me think on that a bit,” she got a downright mischievous grin. “You owe me far more than the fee you offered for using me as a guinea pig for this experiment and you know it.” “I do,” he agreed. “Good,” she replied… because you and I… we have some… unfinished intimate time left to do and this time… I’m gonna be something I like… and you… are gonna join me…” “I can’t wait,” he smiled.
