Day 1:

When it came to new drugs, companies had to do one thing, and one thing repeatedly, test. Companies had to test, and test, and test.

There was a new drug meant to change the very species of a human into that of an anthro. Such a drug had millions of signups, and Brandon was one of the lucky few selected to participate.

Brandon sat in a room that resembled that of a doctor's office. He sat on the plain bed while a doctor typed away at a nearby desk.

"The effects will take a very long time." The doctor explained. "Overall, we expect the process to take over 300 days for your body to adjust. We expect you to come for checkups one day per week for the next three weeks, and then every month thereafter. This is both for psychical checkups; with the correct shots and prescriptions to make sure the transition proceeds smoothly."

"And I'll become a bat anthro after all of this? Will I be able to fly?" Brandon asked curiously. His heart pounded heavily underneath his chest. He felt hot under his white shirt. He already took off his green jacket.

"Yes and I don't know, in that order." The doctor grabbed the needle from the desk. "Are you ready for the first shot? We expect the results of this to be immediate in some manner, but you will still be human."

Brandon nodded. "Yeah, let's not waste any time and get this started." He took a deep breath. He hated needles, but if it made him a bat anthro, he was willing to try it.

The doctor smiled at Brandon. "Okay, you're going to feel a little poke." The female human doctor gave Brandon the shot and injected a clear liquid into him. "It is advisable to wait 15 minutes before leaving in case of any serious side effects, though very unlikely."

Brandon winced at the shot, but nodded once more. He felt a warmth fill his body from the injection site, and watched as the doctor covered up the shot with a standard Band-Aid. "So, what effects are going to be immediate?" he asked out of curiosity.

"The genitalia are usually the first to change." The doctor replied. "Expect to see a sudden shrink in, well to be blunt, your cock and balls."

"Wait, what?"
Before Brandon could get a proper answer, he felt a tingling sensation between his legs. He was ready to take off his clothes right there. The doctor saw him naked earlier after all. He quickly turned away from the doctor and reached down into his jeans. He felt a sudden spurt from his cock, and blushed heavily. "So 'that's' why you said I should do this in that gown." He said to the doctor. He continued to feel his cock shrink in size and, although it didn't vanish, it felt half as big as before, both his shaft size, and even his testicles. "Is this really normal for a bat anthro?"

The doctor chuckled at Brandon's sudden shock. "It IS what you signed up for, and yes it is perfectly normal. Now, I'll see you in a week?"

Brandon opened his mouth to say something. He wanted to speak out against it, but it was too late. The first injection already happened. "Okay, fine." He replied with a soft sigh. "But just because I'm going through this doesn't mean I have to like it."

Day 7:

Brandon wore a yellow shirt today as he waited in the doctor's office. His tanned skin had a hue of white and his hair had a dark blue hue. While his shirt was the same size as his previous shirt, the shirt looked big on him. His ears also pointed up, and his nose pushed inwards slightly.

The same doctor from last week arrived in the room with a smile on her face, and a tray with another shot on it. "Good morning Brandon." She shook Brandon's hand. "This first week has changed your body quite a bit, hasn't it?"

Brandon adjusted his glasses. He had to readjust them multiple times with his smaller nose. "You might say something like that." he commented. His voice was a little higher in pitch, but still deep enough to be manly.

"Would you like to do a physical?" the doctor offered. "Just so I can get a good look at your body from head to toe?"

"Is that really necessary?" Brandon kept looking away from the doctor. "I'm not feeling any pain or noticing any oddities."

"Well, you're going to have to show us sooner or later." The doctor shrugged. "We have to make sure you're transforming properly not just externally, but internally. Your skeletal structure, your organs, your hearing and eyesight, we have to test it all regularly and make sure there's no abnormalities. How is your sex performing between your legs? You said you aren't participating in sexual activities, correct?"

"Yeah, that's right. Even before this, though I do masturbate now and then." Brandon kept looking away from the doctor. "It's a perfectly natural thing to do."

"Of course." The doctor nodded. "Have you paid attention to how much you cum when you masturbate? Has the amount changed?"

"On a scale of one to ten, that is a twelve on the way too personal." Brandon's sex shrank a bit during the week, but not as much as it did when he was first injected. Masturbation was hard, but not an impossible task.

"Of course." The doctor nodded. "Well, I'm not going to force you to do a physical, but instead of seeing me, I'm going to suggest a few other specialists for the next two weeks. A visit to the optometrist and an urologist to make sure your eyes and reproductive system are in order. Does this work for you?"

"I guess so." Brandon crossed his legs and turned back to the doctor.

"Is there something wrong?" The doctor tilted her head. "You seem much shyer compared to when we first started."

"No, it's just...it feels a little awkward getting transformed like this, you know?"

The doctor nodded. "You have all the time in the world to get used to it." She picked up the needle she brought in earlier and gave Brandon another shot. "Go arrange those appointments. We'll have a follow up about 21 days from now to see how you're progressing, and I'm going to have to insist on a physical."

Brandon nodded. "Okay." With a sigh, he left the doctor's office.

Once Brandon left, the doctor went to work on her computer and added a side note. "Subject is showing signs of humiliation, may want to ask him about preferences on if he wants a male or female doctor for the future."

Day 32:

Brandon once again found himself in the same doctor's office with the same doctor from before. He took his pants off as per the doctor's request, but the doctor allowed him to keep his red shirt on. Along with bigger ears that looked more as if they belonged on a bat than a human's, his hair changed to a dirty blonde color, and it grew longer. Brandon attempted to cut it now and then, but it always grew back.

"I see your eye test came out okay, and your urology tests also went well. Are you experiencing any significant issues lately?" The doctor asked.

"The urologist said my genitals were no longer functional." Brandon turned away with a blush. His cock was no more than a few inches big. His testicles, while still between his legs, were a very hard find unless one felt for them. "I thought bats had functional male genitals, and it annoyed me to no end to wonder what was going on about that."

"Well, you are becoming a 'female' bat." The doctor casually replied.
"Have you tried masturbating within this past month? You stated you used to before." The doctor seemed perfectly calm about it. She got up from her desk and slipped on two latex gloves.

"How can I masturbate? My clothes barely fit, my arms and legs look and feel much weaker, I have people calling me 'ma'am' at every store I go to, and my cock is so tiny that my pinkie finger is starting to rival its length!" The last part was an exaggeration, but there was no doubt about his much smaller size from before. "You measured it before we did all of this, and now I know why. Maybe measure it again!" He never remembered signing up to become a female bat anthro, but he felt more feminine than manly. "And I did NOT agree to transform into a FEMALE bat anthro! Can't you fix that change?"

"Just relax." The doctor reached down with her hand and gave Brandon's cock a squeeze. She noticed that, as Brandon's body had a much whiter hue than before, his cock and balls were completely white in color. She gave the testicles a squeeze and nodded. "They are no doubt much smaller than before. Do you feel any increased sensitivity behind them?" She stroked a single finger between Brandon's testicle and anus. "Along here?"

Brandon shivered as he felt the finger. "N-no more than usual." He stammered. "Ugh...how can I possibly relax when my body is going through changes like these? You didn't even answer me about becoming a man again."

"Unfortunately once the process has started; it's extremely difficult to reverse. This isn't a fantasy story Brandon." The doctor replied with a short pause. "Well, maybe in one multiverse it is, but in any case, the process takes a long time. Your body has to adjust." The doctor felt his cock with a few gentle squeezes, and padded his balls with her dainty fingers. "There's no indication of swelling. The shrinkage is perpendicular, which is good." With her other hand, the doctor felt Brandon's stomach. "Now, I want you to understand that, along with transforming species, sometimes you can be very emotional. Whenever you feel a bout of anger or sadness, pause and think about your actions. The shift in your body will cause your mind to be uncertain about how to react with these new hormones."

Brandon let out a quiet moan. His small shaft squeezed a bit of seed just with the doctor squeezing him. He didn't feel a strong orgasm though. It felt more as if his cock just couldn't store his seed in his testicles. His mind flooded with thoughts about being a woman. He wondered if they could reverse it once the changes completed, but he felt too humiliated to ask.

"Very good." The doctor released Brandon and took off her gloves. "Now, let's space out our visits a bit more since you seem to be developing quite well. I'm thinking a visit a month from now, and a more complete physical. If you have any problems before then, give us a call."

Brandon sighed. The beginning of the experiment already felt so long ago that he forgot the contract he signed. "You...you really can't do anything about this? I didn't agree to become a woman."

"It was in the contract you signed. We 'may' be able to reverse it once the process is complete, but we can't do anything while it's transforming. There may be some side effects, which could seriously cause harm to the body. Don't worry, being a woman isn't 'all' bad." The doctor smiled.

Brandon grimaced. "Okay, so are we done here until what, like next month?"

"Almost." The doctor put on another pair of latex gloves. "There is one more experiment I would like to run, if you would be so kind as to remove your top."

Just then, a female nurse walked into the room with a large clear container with a twist on lid. The nurse opened up the container and set the lid aside.

"Uh, what kind of experiment?" Brandon hesitated, but he complied with the order to take off his top. His chest was already bigger along with his nipples, but he didn't worry over the size. His chest looked like a combination of fat, and an 'A' cup chest.

"You see, there is more to becoming a bat than the changes between your legs along with some minor physical changes." The doctor walked behind Brandon and placed her latex covered hands gently over Brandon's breast. "I see you have grown here too. How does it feel?" The doctor gently pressed down on Brandon's tits, and then slowly raised her hands upwards with a gentle stroke.

The doctor confused Brandon. Brandon watched as the doctor touched his chest, and then he shivered at the sensations. He felt his cock, however small, twitch eagerly at just the slightest touch of the man. He had a shirt over his chest moments ago, and that didn't give him any pleasure. "I-It...It feels okay." Brandon replied through gritted teeth.

"Are you sure? On a scale of one to ten in terms of pleasure, how does it feel?" The doctor asked. She gently released pressure, but she continued to fondle Brandon's tits with a squeeze to his swollen nipples.

Brandon blushed, and it showed underneath his paling skin. He was glad he was sitting as his legs felt wobbly. He couldn't even reach back to push the doctor away with how intense the feeling was. "E-eight." He hesitated. It felt more like a twelve, but he didn't want to admit it. Despite his twitching cock, it didn't become erect, though he could still feel it fill with pressure just begging for release. 'Oh god, I can't cum just having my chest fondled. I'm a man! Men don't...men don't...ahn...ahn!' Brandon lost track of his thoughts. His eyes rolled upwards as his cock suddenly came.

The nurse was quick to put the cup under Brandon's cock. As Brandon came, his cock pumped and pulsed into the container the nurse set directly between his legs. One hand held the container and the other held Brandon's small testicles as they shrank just a bit more during the orgasm.

Brandon's cock slowly stopped and he panted heavily. He looked down at the nurse in confusion, and then up at the doctor. "W-what?"

"Research purposes, you understand." The doctor replied. She released Brandon's breast and took off her gloves. "Well, one experiment, and one research. Two birds with one stone. You can orgasm from nipple stimulation alone already it seems."

Brandon watched as the nurse closed the container and walked off with a sample of his semen. He turned to the doctor with red on his face. "J-just because my body liked it doesn't mean I did!"

"Of course." The doctor giggled. "You can put your clothes back on. Just as you said earlier, I'll see you next month. Call us if there's any problems."

Brandon put his shirt and pants back on. He struggled to keep his clothes fitting properly, and to get rid of that blush on his pale face. He walked out of the doctor's office, and as he left, he turned back to the office, and then looked down at his chest. 'Just what will change over next month?' He thought to himself. He felt his heart pound with fear, and as he touched it, he felt his body fill with arousal again. He knew having his chest touched before was never this arousing. He truly was becoming a woman. He knew he was becoming a bat anthro too, the white on him showed just as much, but he feared what becoming a woman would bring far more than becoming a bat would.

Day 90:

Brandon laid on his side with his shirt off and a pair of shorts covering his butt and crotch. He looked more like an albino than he did tan, and more womanly than man. His chest pushed out into a B cup over the following days, his hair changed completely blonde and grew so long it covered his eyes regularly. He'd cut the front of his hair, but it grew back in less than a day. His nose turned pink and pushed upwards completely, while his ears poked upwards and tilted around wildly. He could hear a lot better than he used to, but seeing was harder, especially with his hair constantly getting in the way. He also had two small bulges on his back, which made sleeping on his back very hard. He had limited mobility of the things behind him, and he just knew they were the start of wings, just as he also had the start of a tail from his growing spine. He let out a sigh as the doctor examined him. "How much longer? You took many x-rays and you asked about my diet, and so many other things. It's like you don't even know who I am."

"Mentally, I know exactly who you are." The doctor explained as her gloved hands gently stroked Brandon's body. "But physically, every time you come here you are slightly transformed more and more. I am thinking about keeping today's visit short though, as the changes you report seem to be minor. Are there any concerns you have for me today?"

"It's getting harder to see and I'm getting really worried about my breast growing. I know I'm 'becoming a woman' as you said, but dammit I don't want them growing out to huge tits." Brandon grimaced at his chest. He wasn't even worried about his cock between his legs anymore. He still had his cock, but its size was pathetically humiliatingly small. His size resembled the size of a cock one might see in humiliation comics. His testicles were barely even between his legs anymore.

"Well, I can prescribe supplements to assist you if you're worried about that. Are there any sexual changes to report? Physically or mentally speaking?"

"Physically I don't want to talk about it." Brandon huffed and looked away from the doctor. "Mentally, what am I supposed to expect?"

"Well, physically you've gone through a lot of changes; mentally it depends upon your sexual preferences beforehand. If you were interested in women for instance, you may find yourself more interested in men, or at least their cocks."

Brandon remembered when he first asked about becoming a woman. He knew he should have brought it up the moment his cock shrank at the first injection. He wanted to fight over it, but he knew the doctor wasn't going to do anything about it now. "No, I don't have any interest in cocks besides my own." Brandon replied firmly.

"I see, and how 'is' that cock of your own doing?" The doctor smiled.

"I don't want to talk about it. Give me those supplements if they're going to help me with my gender problem." Brandon replied firmly.

The doctor shrugged. "Well, they will definitely help you with your gender problem." The doctor turned back to her computer screen. "And yes, I do see the xrays of your...well, reproductive system. It's quite interesting. Would you like to look?"

The last thing Brandon wanted to see was how much his sex changed between his legs. He agreed to become a bat, but a female bat felt so strange. His blonde hair kept getting in the way of his eyes, his tits swelled, he felt a tail, and his feet felt strange too. However, the only part of his body he cared about right now was the spot between his legs. "I already know how much smaller I am." He replied humiliatingly. He almost swore he felt a surge of transformation occur in his body just with that.

"Oh it's actually much more interesting than that. In fact, if you're ready for the next phase of experimenting." The doctor pressed a button. "Nurse? Could you bring the sample in here please?"

"Wait? Next phase of experimenting?" Brandon felt his heart pound and his body sweat. His white body felt hotter than usual, although he felt that was because of the short fur that he grew. "What 'else' do you have to do? I'm clearly becoming a bat, and a woman one at that. Isn't that enough?"

"Not quite." The doctor replied. "See, it's true you seem to be progressing excellently, but we also want to get as much testing done as possible while you are. Don't worry, we won't ask for too much."

The nurse walked in with a small syringe filled with white fluid. A small sticker on the syringe stated 'Brandon' on it, though the rest was very hard to make out. "Yes doctor?" The nurse asked with a surgical mask on her face.

"Wait, what's in that syringe?" The contents looked familiar, but he didn't want to assume. He also hoped that they couldn't put 'that' kind of white fluid into a syringe; it wouldn't be sterile.

"Some contents for the next experiment." The woman doctor held Brandon's shoulders firmly. "Just lie back and it will be over with quickly."

"I don't remember signing any waiver to agree to that." Brandon felt himself sweat and his heart pound. He glanced to the door, but he saw a third female nurse guarding it. His eyes then glanced back at the syringe.

"You agreed we can perform whatever tests we need to perform that are deemed safe. This includes the contents of that syringe in your body. That said, we do not expect any serious side effects."

The nurse injected the contents of the syringe into Brandon. However, instead of Brandon's arm where he might expect it to go, the nurse injected the contents in a spot below Brandon's belly button, and then she pulled back and nodded.

The doctor released Brandon with a smile. "There we go. Unlike the shot that converted you into a bat, we likely won't see the effects of this shot for some time."

Brandon turned to the doctor with an angry glare. "You still didn't tell me what the shot DID!"

"It's more interesting for you to find out." The doctor smiled at Brandon. "The worst case scenario is that nothing happens. Best case? You'll see. Now, we'll see you in a month?"

Brandon sighed frustratingly. He wasn't going to get any answers out of this doctor. He was thankful that the physical wasn't as detailed as last time, but he wondered how long that would last. "Fine, fine. One month." He replied. His voice cracked into a feminine voice, and when he cleared his throat, his voice felt permanently higher. He couldn't even feel his Adam's apple in his throat anymore. He dressed himself back up and left the office.

A few days later...

The doctor worked in her office alone today. She didn't have any patients, but she had to make charts and details about the patients she had. Just as she was working on her computer, her phone rang. "Hello? Doctor Dalimo's office, Dalimo speaking."

"Doctor?" A female voice spoke on the other line, one that cracked as if it belonged on a teenager. "It's Brandon. Listen, for the past few days, I've been having morning sickness. No matter what I eat, it just comes back up. I'm fine later during the day, but the morning is just so terrible!"

"Yes, that is to be expected." The doctor replied. "Perfectly normal, you should stop after about a week. If you continue to experience it after a week, you may come to our ER and we may treat you then."

"I thought you said there wouldn't be any side effects! I'd call vomiting daily a pretty big side effect!"

"I know its unpleasant Brandon." The doctor calmly replied. "Have you been taking the supplements?"

"Are the supplements the thing causing the vomiting?" There was a sound of a bottle shaking on the other end as Brandon inspected the large white pills.

"No, no. The vomiting is irrelevant. Look, if you're truly worried, we won't stop you from coming in earlier, but because the vomiting is normal, we are unlikely to be able to do anything for you."

There was a moment of silence as Brandon let out a sigh. "Okay, I guess it's just one more month anyways."

"Very good." The doctor replied. "And how are your genitals forming?"

"I don't want to talk about it. You'll see it next month." Brandon hung up the phone.

The doctor chuckled and added a note to Brandon's profile. "Subject has very likely formed vagina quicker than expected. A full body physical is in order to see how large his shaft is."

Day 120:

Brandon stood in the doctor's office with his clothes tossed aside. His arms and legs spread outwards and he let out a soft sigh. He felt humiliation on a scale he hadn't felt yet. His hair was long and blonde. His ears pointed upwards like a bat. He heard much better, but during the month, he went back to an optometrist and got a new pair of thicker glasses, as his eyesight was worse. His glasses were set aside for the time being though.

The female doctor ran her latex gloves around Brandon's body. "I see you're up to a C cup now. Are you wearing bras?"

"I'm still male; I don't need to wear bras." Brandon replied firmly. His voice sounded like that of a woman's.

"Your mouth says male, but your body screams female." The doctor moved down between Brandon's legs and ran her fingers across his crotch. His testicles were long gone. He still had his shaft, but it felt half the size of a pinkie finger in length and width. She also felt something else between his legs right below his shaft. "Oh, what is this?"

Brandon gasped sharply. He didn't want to admit that, during that month, he developed a second opening between his legs. He remembered it opened up partially last night and leaked clear liquid. He didn't want to say anything about it, but he knew what it was. "Y-you already know." He mumbled.

"A vagina, although a bit on the small side I can tell." The doctor slowly inched her hand upwards. "And it looks as if your shaft is developing into the clit of the vagina."

Brandon felt pleasure and humiliation. "I haven't been...I haven't been 'using' that hole though, and it's been getting all...weird."

"How was it when it first opened? Can you describe it in feeling?" The doctor leaned down to get a closer look at Brandon's vagina, and then looked up at him while she kneeled. "This is one reason why I wanted to offer you a free room here, so we could monitor these changes more closely."

"Sorry if I want some privacy now and then." Brandon scoffed. "I don't want to talk about how it felt."

"The sooner you can talk about what happened, the sooner you'll be free to go until next month." The doctor carefully touched what was left of Brandon's cock as she examined it carefully. The color of the shaft was a full pink unlike any normal cock.

Brandon gasped as the doctor touched his cock. He felt his cock twitch, and his cunt moisten. "The night it opened up I shot awake with this strange burning sensation. I felt the opening and felt myself orgasm from it shortly after barely touching it, you happy?"

"It sounded like you were happy after." The doctor smiled up at Brandon. She grabbed his cock with two fingers and gently stroked it up and down. "The pleasure is very intense when you first transform, but it usually calms down over time. Speaking of pleasure how does this feel?"

Brandon didn't want to answer verbally, but his body told the doctor all she needed to know. His cock twitched and pulsed, though it was incapable of becoming erect, blood still pumped through it eagerly. "F-fine. You can stop it now."

"I have to know if you're capable of orgasming from this." The doctor held the cock with two fingers as she stroked it up and down. "You can tell me you have masturbated, but I would like to see if you are still capable of achieving orgasm from this."

Brandon gasped and let out feminine moans. He felt more like he was a woman than a man as the doctor stroked what bit of a cock he had left. "I can't...it's too...that is...I don't know." He didn't want to say it was too small. The doctor clearly proved that wrong.

"Are you too panicked to masturbate? Or has your sexual preference changed?" The doctor asked curiously. "That is a side effect of changing gender too. Some men that were interested in women will suddenly find themselves interested in men, it's perfectly natural."

Brandon didn't want to say 'what' his sexual preferences were. Everything felt intimate as it was, more than he wanted. With another few pulls from the doctor's finger, Brandon felt his tiny cock let loose. His cock came in one large squirt of white seed before it slowly pushed out. Brandon swore his cock felt even smaller after it came, so small that the doctor couldn't hold onto his shaft anymore.

The doctor smiled up at Brandon. With a simple wipe of a wet tissue, the evidence was gone. The doctor tossed away her latex gloves and washed her hands. "Very good. You are making excellent progress to not just becoming a bat anthro, but also a woman."

"I can't help but think you're way too obsessed over the woman part, which I did not agree with by the way." Brandon mumbled. He looked down, but his tits were in the way. "Why don't we talk about me becoming a bat instead for once?"

"We do have quite a few studies about what people experience transforming into a bat, but if you 'want' to answer a few questions regarding it...how are your wings?"

Brandon felt his small wings and gave them a few flaps. "The new muscles feel really weird to control." He commented. "And I don't think they're big enough to fly yet."

"With how big you're going to become, it's unlikely you're going to fly for months." The doctor mumbled quietly, and then she cleared her throat. "What about your tail?"

Brandon looked back at his white tail. The tail measured almost two feet in length and swayed uncontrollably. "It moves with my emotions if you can't tell." He noticed his plush rear underneath it, and then quickly turned his head away.

"Well, that's how many tails move. You might find some control over it eventually. I can tell your vision has changed a bit too."

"The phrase 'blind as a bat' becoming true, huh?" Brandon asked sarcastically.

"Well, many bat anthros do have problems seeing. The majority of them will have glasses or contacts. You won't go 'blind', but you'll have a lot more problems seeing without stronger strength glasses. Your hearing will get much better though. How about your feet?"

Brandon never considered such minor things like his hand and feet. His hands felt normal enough, though covered in a dust of white fur he felt small pads on his hands and palm. He also had his nails, but they turned pink in color. His toes extended outwards a bit longer, but not nearly long enough to sleep upside down with. "They're longer, but I can't really grab anything with them to sleep upside down or anything."

"A lot of 'feral' bats have feet that are...well...they're unpleasant to look at, but they allow bats to sleep upside down easily."

"What if I want to sleep upside down?" Brandon flexed his toes. His toes felt longer, but nowhere near enough to use sleeping upside down. "Like, I have those urges."

"Any other strange urges, like with men?"

"Stay on the bat!" Brandon snapped.

"Right, right. There are things you can buy that allow you to sleep upside down if you get the urges. I wouldn't set it up to be permanent in case you don't like it, but there 'are' things you can do. Your feet likely haven't finished transforming yet too, much like your wings. Now, before I let you go, how is your stomach doing today? You called a while back in regards to morning sickness."

"That passed like you said. I've had some weird cramps, but nothing severe." Brandon paused. "I looked it up out of curiosity because I remembered my mom talking about her morning sickness when she had me. It almost sounds as if I'm pregnant, but I know I didn't have sex."

"Are you sure? I wouldn't judge you if you were sexually active." The doctor smiled at Brandon.

Brandon glared angrily at the doctor. "No, I have had 'nothing' inserted into this...this thing."

"It's called a vagina, Brandon. It's perfectly natural."

Brandon sighed and crossed his arms. He felt his arms touch his sensitive nipples, and immediately pulled his hands back. "Ugh! I'm not sexually active. Just tell me if I should be worried about these things or not."

"No, not at all." The doctor shook her head. "Arrange an appointment for next month and let me know how things progress. Keep a diary if it makes things easier for you."

Brandon knew he wasn't going to get anywhere with the doctor. He swore the doctor was hiding something about his body, but he couldn't figure out what. "Okay, fine." Brandon stood up. "Can I request a different doctor for next month?"

"We can try to arrange one for you, but it's better if you stick with the same doctor for the test, among other things." She casually replied. "Besides, I can assure you most other doctors would give you the same supplements, the same injections, and the same treatments I am giving you, Brandon. If you feel humiliated, realize that could be part of your transformation, and any doctor that might replace me could make you feel just as humiliated, and not because of the way we treat you."

Brandon kept his head turned away from the doctor. He didn't want to admit she had a point. Even out in public, Brandon felt humiliated even being near complete strangers. "Okay." He replied with a soft sigh.

"I know it is tough, Brandon. Your transformation into a bat anthro is actually going to finish within a few months. Just take a few breaths, calm down, and I'll see you next month, okay?"

Brandon nodded. He felt confused, tired, and angry. Brandon dressed up in his new clothes and left the office.

Day 150:

Brandon once again was in the familiar office, but this time with a look of anger on his face. There was no 'him' left in his body. His body was female from head to clawed toe. White fur covered his body, his long blonde hair went just past his shoulders, and his ears flickered with increased sensitivity. He wore even thicker glasses than last time to help him see. The biggest worry about his body however, was his stomach. His stomach jutted out in front of him and he had a sudden increase in weight. His stomach was the 'only' thing that grew though, so he knew it wasn't fat, but something else.

"Good news!" The doctor said as she walked in with an x-ray. She put the x-ray up on a white board to reveal to Brandon. "You're pregnant. It's too early to tell if it's a boy or girl though, but I can definitely tell you there's more than one in there!"

"What the fuck?" Brandon felt ready to lunge at the doctor. "HOW? I am not sexually active, I told you that already!"

"Brandon, you called earlier about your belly and I told you not to worry about it. Pregnancy is nothing to be concerned over; it's completely natural for a woman to get pregnant."

Brandon took a deep breath, and smiled at the doctor. His teeth hadn't changed too much, and he was glad for that. "Yes, pregnancy is natural and normal. You know what isn't normal?" He grimaced. "Becoming pregnant WHEN I NEVER HAD A DICK IN ME!"

"If you were injected with semen, then that could also make you pregnant. Don't think about it too much Brandon." The doctor grabbed a clipboard and began to take notes. "Now, I've already seen the rest of your body. It looks like your transformation to a bat is nearly finished. Your wings and tail haven't fully grown in, but they should accelerate now that the rest of your body is finished."

Brandon didn't even pay attention to his tail and wings. His wings doubled in size from last time and they were a bit bigger than his shoulder blades. His tail measured three feet in length. He didn't think bats had long tails, but he wasn't worried about that. "But..." He remembered the syringe from a few months ago. "You. You injected me with semen. It was my own semen, wasn't it?"

The doctor shrugged. "It could very well have been, but that's irrelevant now. It's now not so much a matter of watching your transformation into a bat anthro, but to see how your pregnancy goes."

Brandon wanted to strangle the doctor, but along with his big belly, he was also much slower. He felt cramps, which just made it even harder to move. "This is unbelievable. You expect me to just go through this pregnancy?"

"You don't have to keep the children if you don't want to." The doctor replied casually. "But imagine how much we'll know. A man, not only changed into a bat anthro female, but also pregnant with a fine birth. It's the dream of many men to become a woman, and be able to become pregnant."

"It's not MY dream!" Brandon retorted. He sat on the bed and crossed his arms underneath his breast.

"Well, regardless, it's what's happening. We'll do whatever we can to make you more comfortable during this process. One woman a few months ago had their breast milked, and they found it very pleasurable. Perhaps you might like it too?"

Brandon shook his head. "No, and don't refer to me as a woman."

"Brandon, you have no cock. You have no balls. I've seen you grow wet with arousal between your legs. You can say you are male, I will not judge. However, your body is physically built as a female now."

Brandon leaned back on the bed and sighed. "Okay, fine whatever. Since we're just tracking my 'pregnancy' now, does this mean the visits will be shorter?" He folded his wings against his back. He wanted to try flying, but now his belly felt far too heavy. Worse yet, he felt as if his belly was as big as a full-term pregnancy, yet it was only a month.

"Unless you want your breast milked, yes." The doctor explained. "I doubt you'll be able to fly until your pregnancy is over, but the good news is your wings should form completely in the next few months, but your pregnancy is expected to be as long as a human's at around nine months."

Brandon had no desire for the doctor to milk him. "Hard pass."

The doctor shrugged. "What about your name?"

Brandon paused. "What 'about' my name?" he asked with a raised brow.

"You are a woman. The name 'Brandon' doesn't fit well on a woman. With this transformation also comes a free name change if you are interested."

Brandon crossed his arms in a huff. He didn't identify as a woman, and he certainly didn't identify with a new name. "No. Hard pass. We're done here." He didn't want the doctor to get in another word.
He hopped onto his feet, and then groaned. "Ugh, damn belly..." his feet felt a bit sore after walking with such a huge belly. He walked away with his tail flickering behind him.

"Take care of yourself." The doctor called out as Brandon walked away. "Eat, drink, and relax properly. You're going to be a mother."

Brandon simply raised the middle finger to the doctor as he left.

The doctor chuckled and turned back to her computer. She changed Brandon's name to Brianna in the documents, and proceeded to start writing emails. "Oh, she'll accept this, whether she likes it or not."

Day 180:

Brandon couldn't even wear his normal clothing anymore. He had to wear a muumuu shirt, a very large bra, and panties to cover his crotch. He couldn't wear pants without them digging into his ass. His belly looked twice the size a normal pregnant belly should have been. His wings grew out to the size of his torso, and his toes almost resembled fingers in length. In fact, he could actually grab things with his toes, and very firmly at that. While he was female physically, he still refused to refer to himself as such.

"Well, it looks like you're coming along very nicely." The doctor smiled at Brandon. "How do you feel?"

"I'm tired, it's hard to eat, I have to pee with this new cunt a lot, my belly is bigger than it should be, and worse yet, everyone continues to keep referring to me as a woman. It's hard to even DRIVE with a belly like this!"

"Well Brianna, in regards to a lot of your fatigue and stomach problems, your pregnancy is no doubt bigger than a normal pregnancy. I don't know how many children you have, but I imagine at least nine growing in there. People also call you a woman because you 'are' a woman. You don't have to accept this, but you're a woman physically speaking. This test does come with a free name change, I'm thinking 'Brenda' if you're up to it."

Brandon glared at the doctor angrily. "No." he replied, firmly. "Is there any way to speed this pregnancy along? My tits and feet are killing me." 
He also heard the doctor call him by Brianna. He hated that name. He identified as Brandon. He didn't want to say 'everyone' called him Brianna now for some reason, and he wasn't sure why. He even obtained 'updated documents' that specified his gender as a woman, and his name as 'Brianna', he assumed it was all a prank, but all of the paperwork looked legitimate when he obtained it.

"Unfortunately no, but you can always get your tits milked if you would like." The doctor pointed behind Brandon's head.

Brandon turned around and noticed two clear suctions from the ceiling. He didn't see them when he came in! "Seriously?"

"Well, it's that or you can wait it out. You can solve your sore feet problem by not walking around as much. Your job must have given you maternity leave by now."

"Yeah. Surprised they didn't reduce my pay the moment I told them I was a woman." Brandon scoffed. With a sigh, he raised his muumuu above his large tits, well above the DD size, and opened up his bra to reveal his pink nipples were now a darker brown and swollen to three times their normal size. He grabbed the suction cups and placed them around his nipples. "I'm not doing this every day."

"Well, I wouldn't advise it unless you wanted more milk. I would do once a week at the most, and once a month at the minimum, so every visit." The doctor smiled at Brandon. The suctions began the moment Brandon placed them on his nipples.

Brandon gasped as he felt a suction push and pull at his breast. He watched as milk flowed from his nipples into the clear suction and then up the tube. "W-where does that tube go?" he asked. He hated how much his body loved it. His cunt felt wet, his long toes curled, and he quietly moaned in pleasure.

"It goes into a machine that puts the milk into a small vat and marks it with your name. Should you desire to bottle-feed your children, we can use that so your teats don't get sore. It's a much cheaper and healthier alternative than buying the store milk."

Brandon hated the idea of having children. Worse yet, there would be no father to take care of them. Still, he knew it wasn't the children's fault over this whole experiment. He couldn't let them be born into an uncaring cruel world with only each other. "Ugh." he groaned. "You're making me feel forced into doing so much shit I don't want."

"You're free to remove the suctions at any time and the machine will stop automatically." The doctor shrugged. "You're not being forced to do anything. Much of your transformation into a bat anthro is complete. Your wings will fully form in a bit, as will your tail grow long."

Brandon sighed. He wanted to get this over with now, but he still had months to go. "Fine, whatever." He let the machine milk him for a few more minutes before he pulled himself free and covered himself back up. "So humiliating."

"I know Brianna. How about we schedule the next visit a few more months out instead of one? If you have any problems, you can come see us earlier, okay?" The doctor smiled. "Your body is adapting very well to these new changes. I want to make sure your mentally adapting to it as well."

Brandon sighed. He felt his nipples leak in his bra, but he didn't care. His nipple leaking was the least of his worries. "Do you have to keep calling me Brianna? Everyone keeps calling me that and it's stupid. My name is Brandon."

"You're a female bat now, not a male human. Brandon is gone physically. You want to go around telling everyone who you used to be, and then it's going to get complicated. It's best you stick with a new name like Brianna."

Brandon groaned. "Fucking...okay sure whatever. Call me pineapple for all I give a shit." He knew his name was Brandon, and he did not intend to change it.

Day 220:

Brianna returned to the hospital in a wheelchair. She wasn't injured; she just couldn't walk anymore with her belly. Her stomach was almost bigger than she was, and her belly had light white fur covering it. Her wings expanded the entire length of her body, but she was incapable of flying with her massive stomach. Her tail was almost six feet long too, but she wasn't concerned about that.

The doctor walked into the room and smiled at Brianna. "You're coming along quite nicely. How far along is this? Five months? Or maybe it's six."

"I did 'NOT' think bellies could stretch this much." Brianna said with a groan. "This is unreal. No stomach should be this big, let alone with children."

"Well, in a few months' time, your water will break and you'll have many children." The doctor kept her smile. "The good news is we don't need to do a physical, but we can do an ultrasound to check on the children if you so desire."

"I just want this to be done and over with!" Brianna said with frustration. "It's so hard to do anything when your stomach is so big someone could use it as a beanbag chair."

"Well, in truth we don't know how long your pregnancy will last. We assume as long as a human's because you are an anthro, but also you are part bat, and they do have pregnancies that don't last as long, so it could always be shorter."

"But look at how big I am! I can't even walk like this!" Brianna pointed at her massive stomach. "And what's worse are my cravings. You know how weird it is to get ice cream topped with pickles and hot sauce? I felt like a freak!"

"Well, strange hunger cravings are a natural side effect of pregnancy. To many it will taste weird, but if that's what you crave, then you can eat such food without worry. So long as all of the food you eat is cooked and prepared properly as needed, you'll be fine."

Brianna huffed. It was a challenge to cross her hands with her big belly and tits anymore too. "Dammit...I hate this."

"That could very well be you being overly emotional. Along with becoming a woman, pregnancy can fill you with all sorts of conflicting emotions. The good news is that your transformation seems to be finished physically. Your wings and tail look fully formed, your body is covered in white fur, and you have the blonde hair and bat face, tits, an ass." The doctor tilted her head downward. "You also have long bat toes for sleeping upside down. Not that I'd recommend it as your weight is undoubtedly much bigger due to this pregnancy, but once you're finished then momma bat can sleep however she so pleases."

"No, I'm pretty sure I hate this just because I hate this." Brianna groaned. "I keep feeling them kick."

"Would you like an ultrasound to see how many there are?" The doctor smiled. "You know, some men would kill to become pregnant, and I know a lot of women would kill for their man to become pregnant too. Point being, this is very special in many ways."

Brianna was ready to shout that she didn't want anything to do with these children, but she felt a concern over them, one she knew was supposed to be natural for a mother to feel, but the transformation being unnatural made her feel uneasy about such a 'natural' feeling. "Fine, whatever." She said. She sounded unenthusiastic, but in truth, she was curious.

The doctor chuckled and helped Brianna with the wheelchair. She brought her to a small operating room with an ultrasound machine set up. "Can you get up on the bed, or do you need aid?"

Brianna heaved herself up. Standing was hard, but she could do it, just not for long periods. "My feet get sore after less than a damn minute." She got onto the bed and laid on her side. Her massive belly barely had any support. "Uhn. Can you get a second bed in here or something?"

The doctor brought in a nurse with a second bed to help support Brianna's belly. The doctor then rubbed gel on Brianna's stomach. "Now, it would take us forever to get a view of your entire stomach, so we're just doing a bit for now." She shifted the screen up for Brianna. "You see it okay?"

Brianna shivered as she felt the gel on her body. "Feels cold." She muttered. She raised her head up to see the black screen, and nodded. She clenched her bat toes nervously. She never imagined in her entire lifetime she'd become, not only a bat anthro, but also a massively pregnant one.

The doctor put the scanner up to Brianna's belly, and the screen showed one of Brianna's many children in her womb. It resembled most ultrasounds with the child curled up into a ball, and a small cord out of their belly going into Brianna. "Now, you must be experiencing a lot more hunger with this many children inside of you, correct?"

"On levels you can only imagine." Brianna replied. She felt hunger as it was. "And I told you about the strange hunger cravings."

"Perfectly natural for any pregnancy." The doctor chuckled. "We can supply you with more money to help you purchase food online so you don't have to travel. Alternatively, perhaps you'd like a hospital stay. I can only imagine how difficult walking must be for you in general, especially if you came here in a wheelchair."

Brianna's feet felt sore on a regular basis. She wasn't even sure 'how' she could walk in the first place with a belly as big as she had. The thought of staying in the place that transformed her into a woman repulsed her. "A hard pass." She kept her head turned away from the doctor. "Can you tell me how many kids are in there?"

"Well, your pregnancy is unlike any other." The doctor ran the scanner along Brianna's huge stomach. "I can only see the children on the surface. There are undoubtedly more of them inside. Have you considered a closer examination? A...hands on one?"

"Yeah, let's just ask stretch Armstrong if he can stick his arm in my vagina and count how many kids are in here." Brianna scoffed. "Look, how is this even possible? I put two and two together and realized that you must have injected me with semen, but there's no way I can be this pregnant naturally."

"It is unusual, but not unheard of." The doctor released her scanner. "You have well more than twenty children in there I'd estimate. Perhaps thirty counting the ones hidden, maybe more. You also have to remember how much semen is in one...let's just call it load."

"Yeah well, name one human or bat that's had more than ten children in one birth."

The doctor shrugged. "I'd call it a miracle, but that's just me. Now, what do you want to do? You can always go back home, but I would not recommend physical activity of any sort. Period. Sit, relax, and get your breast pumped on occasion."

"Why would I need to get my breast pumped?"
As if on cue, Brianna's tits leaked slightly into her clothing. She didn't have to apply anything to them. She felt a constant fullness in both her stomach and her tits, but she'd deny it if asked.

"For one, a lot of children means a 'lot' of breast milk, regardless if you intend to breast feed them or not. Two, I can tell you very much enjoyed the process last time. We can give you a home version, but it would be much easier for you if you left it to the professionals."

Brianna's eyes leered. She turned her head away to think about it briefly before she turned back. "Fine, whatever. Ten minutes should be plenty, right?"

"Well, it might be a bit longer." The doctor wheeled over another machine with two familiar suctions. Unlike before however, this machine was visible. It looked as if it stored the breast milk inside of it. "This should do the job."

Brianna pulled up her muumuu with some effort, and unclipped her bra with none whatsoever. Her nipples were a dark pink and heavily swollen at the base. She thought it looked disgusting how it stuck out from her fur. She grabbed the cups from the machine and attached it to her nipples. "Start it up and leave me alone."

"I'm afraid we can't leave you in the room alone." The doctor replied, though as requested, she started up the machine.

Brianna let out a sharp gasp as the machine started. She didn't need to hold onto the clear suctions anymore. They did the job for her. She watched as milk flowed freely from her nipples into the machine, and her long toes curled. She moaned quietly as the pressure from her tits were relieved thanks to the machine. She could only hope one day that the pressure in her stomach would experience relief too. She knew her pregnancy had to end at 'some' point and it couldn't end soon enough.

"You can always do this at home if you so desire. I have a feeling I mentioned that, did I mention that?" the doctor tapped her chin with a pen before she just shrugged. "Well, anyways, you can do it at home. There are kits that allow you to do it, but the machines here are going to be far more effective at the job. Stay as long as you need."

Brianna's eyes rolled up to the top of her head. She felt her cunt grow damp. She was ready to orgasm from just having the milk machine go at her tits. She went quiet as the milking machine did its job, but her toes kept curled and her wings folded. She'd let the milk machine pump away at her tits for a good fifteen minutes before she spoke up. "Y-you can stop it now." She would have gladly done so herself, but she couldn't reach the button to turn it off from where she laid.

"Oh? But you're not even close to empty." The doctor replied as she watched. She sat in a plain hard chair with a smile on her face.

"I-I said you can stop now." Brianna grimaced. She didn't look down at the doctor, but she tried to reach the button to no avail.

"I heard you the first time; you don't have to repeat it. You're not nearly that empty though. Why, you'll fill up in less than half the time it took for the machine to milk you!"

Brianna let out a soft moan. She didn't want to say that she felt her tits already fill up with milk. Sure, the machine milked her and it took off the pressure, but she continued to feel herself swell, just not as much as before. "But if my body gets too used to this then it'll produce even more milk."

"It's already producing quite a lot as it is if you can't tell! Why, I bet you could fill up the machine and then some with all your milk. You do have many children in the womb too. There's no way you're going to be able to breast feed all of them effectively."

Brianna barely wanted to breast feed any of them. She wondered what kind of man would ever want to go through this, let alone women. "Fine, how much longer do you think I should stay here then?"

"About three or four should be good for the rest of the day I'd imagine."

"Minutes?" Brianna sighed of relief. "I can manage that."

The doctor chuckled. "I was thinking more like three or four hours."

Brianna's sigh of relief quickly turned into a groan of torment. "Fine, whatever." She felt more humiliation and embarrassment. She wondered how things could get worse, but she dared not to say it aloud.

"Do you need something else to help pass the time?" The doctor suggested. "I have another machine that can help you with that."

Brianna grimaced. She didn't look to the doctor once. "I'm afraid to ask what kind of machine it is."

The doctor smirked and went behind Brianna. She wheeled in something from the back. "Now, you might feel a little cold at first." She lowered Brianna's panties from behind before she stuck a thick metal rod in Brianna's vagina.

Brianna felt as if she had gasped so many times before, but it was the best way she could describe what the doctor did to her body. "Fuck!" She shouted. "That is COLD!" Despite how cold the rod felt to Brianna, it also felt so good to have something in her, although she refused to admit that aloud.

"But the question is, how does it feel pleasure wise?" The doctor flipped a switch.

The cold sensation slowly faded, and instead Brianna felt the machine vibrate in her cunt. She let out a lewd moan as the device vibrated. She could tell the device had the shape of a dildo, and a vibrating one at that. The doctor put a vibrating metal dildo in her while the other device milked her. "Un...unbelievable." she moaned out. "God...s-stop watching, pervert!"

"I'm afraid I have to make sure everything is working properly, so I can't leave until you're finished." The doctor casually explained, though she had a sly smirk.

Brianna let out a groan. She let the machines do their work. While she resisted showing off any faces of pleasure, she couldn't help but let out an occasional moan and even orgasm, but she did as quietly as she could. 
After a few hours, the milk machine automatically turned off. "Finally." She mumbled.

"Your breast isn't empty. It's just that the milk machine is full. I'd advise coming back every week to get them milked here, unless you're going to do it at home, but if you are milking at home, then I advise every 3-4 hours unless sleeping."

Brianna wanted to just hop down and walk away. She reached back and pulled the metal rod free from her cunt. The rod was soaked by now. "Ugh...I'll figure it out." She mumbled. She pulled herself up with extreme difficulty and got back in her chair. The chair felt as if it were ready to burst underneath her weight, but she didn't care. "I'll see you later." She didn't care to adjust her panties or bra again. It just took too much effort. She wheeled herself out of the room, and out of the building.

Day 300:

Brianna's pregnancy felt like it lasted an eternity. She made it back to the hospital and sat in the waiting room. Her feet throbbed with pain. It was a struggle to get even a few good steps with her massive size.

The doctor smiled at Brianna as they were in the familiar room Brianna went to so many times before. "The good news is you're so far along that it looks like you're ready to birth those children any day now."

Just as the doctor finished her sentence, Brianna let out a gasp. She felt a sudden pain and a surge of water rushed out of her cunt. 
Brianna immediately knew what it meant, and blushed heavily underneath her white fur. "Ugh...you've got to be kidding me." She knew what was going to happen next. She loathed the idea of going through it firsthand, and she felt her heart pound fearfully.

The doctor watched with wide eyes. "Speak of the devil. It's a good thing you're already at a hospital that can tend to you. Stay sitting, I'll get you checked in and you'll be done before you know it. Many women get drugged up so much they barely even remember everything that went on!"

Brianna gasped and breathed in and out. She felt a growing pressure between her legs as 'something' began to work its way down. There was painful stretching, but not so painful that she couldn't stand it. "Just fucking do that to me then. I don't want to feel or remember any of this!"

The doctor chuckled. "Calm down, it will be all over before you know it."

The doctor was true to her words. The things that happened next went by quickly. The doctors properly set up Brianna in an operating room, and the doctors gave her enough drugs to make the procedure go by quickly and painlessly. She didn't even remember most of it. She remembered laying in a bed and pushing out a bat child repeatedly. She also remembered intense pleasure while birthing, as loathe as she felt enjoying it.

After what felt like hours, Brianna laid on a bed with her belly still swollen. According to what she remembered from the doctors, they said she finished birthing, but her belly hadn't reverted to its original size. She held two of her many children next to her breast as they fed from her nipples. She still felt humiliation, but she also felt something she never thought she'd feel in her life, and that was a mother's love. She knew there were multiple children, all of whom the nurses attended to, and while she knew it was going to be a challenge, she planned to care for all of them.

Brianna also planned on flying, now that she was free of her pregnancy. Her transformation into not just a bat anthro, but also a pregnant female one was interesting to say the least. She still loathed the people that transformed her female, but at the same time, she had never felt happier.

The doctor came in with a smile on her face. "Well done Brianna. Your stomach should go down to normal in time, but the stretch marks underneath your fur might stick around for a while. We're all quite thrilled to see such a success of, not only a bat anthro, but also a female, pregnant one who gave birth to so many healthy children.

Brianna sighed. She hated how she just accepted her name, but she grew into it over time. "Yeah." she still felt a bit out of it. "Well, now what?"

"Now we'll give you a few options." The doctor pulled out a clipboard with a piece of paper on it. "If you desire, we can attempt to turn you into a male bat anthro. You'll have the genitals of a male bat, but sized appropriately to that of a human's own. We developed this during the time you changed into a female bat, so we are not truly sure how this works. The problem will be that you will not be able to care for your children effectively."

Brianna sighed. A male bat anthro was what he wanted to become in the first place. Now, she had children, she had a new name, she had a new life. "I can stay like this for a little while longer I guess, for the children."

The doctor smiled. "Very well. Now, we also did mention we were paying you for this in the beginning. Because of how successful the results were, we have changed that payment to this." The doctor pulled out a check and showed it to Brianna.

Brianna grabbed the check. She felt more and more awake, but the moment she saw the check, her heart leaped. "That's...that's a lot of zeroes."

"Yes, it should be enough to care for your children and you for the rest of your natural life, including a house big enough for all of you, and the servants to care for your children so you can do the things you want to do, such as flying."

Brianna smiled softly. She put the check down, and looked to the doctor. "Well, this has been a fucking roller coaster, and this is one huge reward. I do have one question though."

The doctor nodded. "What is it?"

Brianna brushed her belly. "Could I get pregnant again, but in a more natural manner? Like...cock into cunt?"

The doctor shrugged. "You know, we don't know. If you were willing to test that, we could pay you for your trouble as well."

Brianna grinned. "Oh, I know just who to call to help."

Brianna left later that day a new woman. She felt so relieved she could walk again without foot pain, although she felt a little empty without her children. The doctor told her she should find, or get a place built, to help her with the children. For now however, she felt empty and horny. She was a new bat on the town and this was her first night free in what felt like ages, and she was ready to fly, and quite possibly, experience sex from the other side.
