In the far future, humans are born androgynous and pick a gender once they reach adulthood. Vance and Jim both decide to be men, but things get awkward when Vance develops Sudden Male Rejection Syndrome and, over the course of minutes, goes from the masculine ideal to a curvaceous, female bombshell.

Prologue
The more things change, the more they stay the same.
It was an old saying, but it was true. The human race had come quite a way by the year 3025, but some things never truly changed. Like Perth. It was a megacity just like any other, but Australia was still Australia, and the desert wasn’t going anywhere. So even with hyperlanes, advanced AI, the internet and a host of other technologies that kept the world connected, living in Perth still felt a bit like living on one of the colony planets. Advanced, crowded and yet strangely isolated all at once. Not that Vance had ever been to a colony planet, but he heard about them enough on the news to know that he was an Earth man through and through.
Or at least, he was a man now.
Humanity had long grown past the concept of gender at birth. There were a host of factors that they all learned in school that led to that. The eugenics wars, the perfection of artificially grown humans, and the conservative uprising that insisted all children not even have access to their ‘reproductive organs’ until they were old enough to understand them. Honestly, for Vance and most others, it was ancient history that didn’t matter anymore.
It was all long past, and all that remained were the aftereffects: humans were now born physically androgynous. Any time after their eighteenth birthday, they were able to apply for a catalyst to turn them into their desired sex.
Vance had waited an extra few years, not because he was unsure, just because he was nervous. Not that he wanted to admit that. Sure, he had control over what sex he would become, but that was it. His body would change in almost every way; he could get darker hair, his facial shape could change, and his whole build was definitely going to change. After twenty years in his flat, sexless body, he was a little nervous to exist any other way.
“We can’t put it off forever, “ his best friend Jim said one day, “We just need to take the plunge. Tomorrow. We’ll do it together.”
That was easy for Jim to say; he was tanned, with sandy blonde hair that had that distinctive Australian sunbleached look to it. He’d look handsome no matter what form his catalyst took. But Vance, he was just the opposite; pale, with dark hair that made him look even paler. The fact that his main hobby was playing video games and building model kits, while Jim’s was surfing, only made the difference in their looks more apparent. What if he ended up one of those gaunt men who looked like a ghost wandering the streets?
All Vance had ever wanted was to be somebody people looked at. Not in a strange way, but one of those people with a natural charisma and look to them that drew the eye. To be strong, tall and eye-catching; that was the dream. What if he took his catalyst and ended up the same: reedy, thin and unremarkable?
He knew Jim was right, though. The longer he put it off, the worse his anxiety became. So off they went, the very next day, to get their catalysts. It was insane, holding the tiny syringe in his hand, knowing it held his entire future inside. He’d swallowed nervously, then both he and Jim had stabbed their respective needles right into their thighs.
The next week had been agonising. Not physically, but emotionally. Every time he woke, Vance would check himself over, trying to see what new parts of him had grown, and to his delight, things seemed to be going his way. He packed on muscle, his shoulders grew broad, his jawline sharp, he even grew to be over six and a half feet tall! By the time his new body was done, he looked incredible.
His reflection in the mirror stunned him. He had hoped just to be a normal, good-looking guy, but this exceeded even his wildest expectations. His chest was a shelf of hardened muscle, and his hands were now thick-knuckled and strong, even slightly calloused like a fighter’s. His voice, when he spoke aloud just to hear it, rumbled from his throat, deeper than he imagined it could be.
It wasn’t just appearance. There was a presence to him; the very thing he had always wanted. When he walked, he could feel the power in his stride, the way people’s eyes tracked him down the street. The way some flinched, and others lingered, especially the women.
And the confidence. Gods, the confidence. He'd never realised just how much he hunched before. Now, Vance held his head high with pride, which only added to his aura in a room. He felt powerful; almost a little arrogant, knowing that this was who he had always been deep down, he couldn’t help but feel a little smug. Why had he wasted two years when he could have been like this so much earlier!
But underneath the pride, there was also a quiet, bone-deep relief. The transformation had worked. He had arrived. And no one could take this from him now. When the time came for him to go see Jim and reveal themselves, he almost felt sorry for his friend. Jim was an average-looking guy, athletic build that suited his surfer dude natural looks, but he was nothing on the pinnacle of masculinity that was Vance’s new body. Even so, he was attractive, and butterflies danced in Vance's stomach.
“Wow, you sure are something…” Jim muttered, circling Vance like a shark. “You’re like…the manliest dude I have ever seen.”
Vance just grinned. “Hell yeah, I am.”
Jim looked nervous for a moment, then walked over to his desk and grabbed one of the many medical textbooks he had stored there.
“We were learning about something in class the other week.” He muttered, Jim was a nursing Major at Perth University, he’d only just started, but he was passionate. If he wasn't surfing or playing Video games with Vance, he was studying. He bit his lip as he flipped through the pages.
“Maybe it’s nothing but…you look like you might have SMRS.”
“Smuuurs?” Vance smirked. “What?”
“Sudden Male Rejection Syndrome.” Jim explained, “Here!”
He spun the textbook around to a page filled with tiny, jargon-filled medical text. Vance felt a stab of irritation; Jim was supposed to be admiring his new body, not ruining the moment with medical issues.
“Think you could summarise for me?”
“Basically, sometimes a male catalyst takes a little too hard, then a few days later, the body rapidly changes to female. A hormone imbalance, mixed with a fault in the-”
“Nah, that’s enough of that.” Vance rolled his eyes.
“Look, I know it's rare, but you’re so hyper masculine I think it might be smart to take precautions over the next day or so.”
“I’ve been male for over a week.”
“Because the catalyst is still settling. Normally, SMRS activates at about the eight-day mark after injection.”
Vance just shrugged. Clearly, Jim was a little jealous, that’s all. He’d get over it. Vance didn't have time to worry about obscure medical conditions; he had bigger, more important things on his mind. Things he’d been planning for years at this point. Things that, now that they’d both taken their catalysts, he could put into motion.
Part 1
One of the downsides to being androgynous is that dating is hard. People liked to pretend that gender didn't matter, but it did, and if you didn’t find women attractive, only for your long-time partner to become one, well, it caused problems. Because of that, most people didn’t even start dating till they’d taken their catalysts these days. That and the fact that hormones were so minimal pre-change that people didn’t really feel the need a lot of the time.
Vance, like most people, felt the testosterone hit him like a truck. He’d always had a crush on Jim and was lucky enough to be bi, so it wouldn't have mattered if Jim decided to become a woman. Secretly, though, he was glad they were both men; he’d always leaned more towards them than women.
Things couldn’t have worked out more perfectly; he had his dream body, Jim was a man, and they were both right in the middle of the post-change hormone tornado. Vance’s dreams were filled with all sorts of sinful images of his friend, and he woke up that first day hard for the very first time. He took a moment just to look at the tent formed from his sheets with fascination and a little pride; it was quite sizable.
His hand snaked down his muscled torso to grip it, and Vance groaned; a few pumps was all it took to experience his first orgasm. The stories he’d read were true; it really was the best feeling in the world. He could only hope he’d get to feel what it was like with somebody else soon.
He had it all planned out, a trip to the local beach. Not the busy one in the city, but one of the many quieter little coves that littered the highway outside of Perth. The beach was the perfect place to find out how amenable Jim was to the idea of being more than friends. He could show off his new body to its fullest and see if he caught Jim looking, and as an added bonus, he would get to perv on him in turn. They hit the sand, and Jim grinned, looking at the giant expanse of blue before them.
“This was a great idea, man.” He teased, putting special emphasis on the last part. “I wonder how much better I am at swimming now with this extra muscle.”
“Well, good luck keeping up with me?” Vance grinned, flexing his new biceps. “I feel sorry for the sharks; if they want to make a meal of me, they’re going to be disappointed.”
“Are you implying you can outswim a shark?
“Or out-punch it.”
Jim snorted.
“Come on, let’s go swim.”
Gliding through the water in this body was like a dream. One stroke sent him torpedoing through the water twice as fast as the last time he’d been in the water. The current and waves were bowing to his will; he put his back to the swell and let it crash over him, laughing when Jim’s feet went out from under him and he ended up underwater. He rose back up and laughed, running his fingers through his golden hair. The sunlight bounced off his wet chest, and Vance felt his stomach fill with butterflies. Jim really was a hot guy; even if he wasn't quite as masculine as he was.
He was trying to think of how to broach the subject. Should he start soft? Or just scoop the guy off his feet, literally; he was more than capable of it now. Big moments like that always went over great in movies and such. Probably a bit weird if things didn't go his way, though. Words it was. Vance took a deep breath.
“Ah!”
Instead of words, a yelp of pain escaped him; it felt like something had just stabbed into his crotch.
“You okay?” Jim called, and Vance forced a smile.
“Fine! I think I just…” The pain stabbed again, “I think I stood on a shell or something, hang on, I’m going to swim back to check it out!”
He dove down into the water and began swimming. With each beat of his heart, the pressure between his legs intensified, which only made his heart race faster. The pain seemed to crescendo just as he clambered out onto shore. It was like somebody had his cock in hand and was squeezing the life out of it. He managed to stumble behind some of the rocks at the edge of the beach, and then, the pain just stopped. Like somebody snapped their fingers, only now, he couldn’t feel his dick at all.
Jim’s warning about SMRS swam through his brain, and Vance swallowed nervously before tentatively reaching down to grasp the waistband of his swim trunks. He knew, deep down, before he’d even pulled them away, what he’d see: nothing. No, not nothing, but there was certainly no cock hanging between his legs anymore, no balls either. All there was was a mound of neat, curly hair in a very distinct shape. He had a vagina.
He was becoming a woman.
Vance felt his mouth go dry; her mouth go dry? His gender was up for debate right now. Except, no, it wasn’t, because there was no denying it now, he had SMRS, and that meant that within a few hours, he would be totally female. Funny, the places panic takes your mind to, because the very first thing Vance thought after realising what was happening was: Guess I’d better pick a new name.
Vance wasn't going to suit her much longer. The obvious choice was Vanessa; it would do for now. Or forever, the latter was probably more likely. She could deal with the whole gender disappointment thing later; right now, what she needed was to get out of here before she embarrassed herself. When Jim said the change was rapid, he meant it. Vanessa’s chest was already starting to change; her rock-hard pecs were turning soft and supple, and her nipples larger and more prominent. Vanessa peeked out from behind the rocks and looked at the long stretch of sand between her and the car park, and half a dozen bathers who were walking across it.
The walk down to the water didn’t seem that long, but now that she was rapidly becoming a topless woman, it looked like a mile. Maybe she could sneak back into the water and let it hide her growing chest. Of course, that would mean running into Jim and admitting he was right.
“Maybe I can risk the sand.” She muttered. “Or the rocks.”
Rocks just like the ones she was hiding behind framed most of the beach. If she were careful, she could continue behind them, climb over a few and sneak back to her car. Then she could call Jim’s phone, leave a voicemail and drive out of here, hopefully with some shred of her dignity still intact.
She started off, ducking behind the rocks to avoid the nearby sun bathers and stumbling as her feet began to shrink. The soles of her feet got softer, and she winced, climbing over the sharp shells and barnacles that clung to the stone. Her hands were doing the same, fingers becoming more dexterous, but softer and delicate at the same time.
The sound of laughter made her drop to her knees, breasts hanging low as a couple jogged past on the other side of the rocky barrier. She kept crawling, groaning as she felt her ass start to take on a more peachy shape. Each crawl forward made her new breasts sway slightly as they continued to grow heavier. This was so embarrassing. Her swim trunks were starting to struggle as well. They were tight; she’d picked them to show off her muscular form and a not-so-subtle hint at the package in her pants. That was long gone now, and the fabric was starting to stretch across her ass cheeks.
Even the way she walked was changing rapidly; it was subtly different every step she took. Each time her hips had more sway, her balance was different, her feet sank into the sand a little less or more. Her confident, male stride was gone, replaced with an awkward feminine sway that she didn’t seem to have full control over. She glanced back over her shoulder, feeling them slim and slope slightly. Jim was still in the water; what would he think if he saw her, half-formed and flailing like a newborn deer? She would never live it down, forget dating, Jim would never take her seriously as a person again.
The trip across the back side of the beach wasn't long, but it felt like it took an age. Her body was rapidly transforming now; while it had taken a full week for her masculine form to take, her new one was coming on in a matter of minutes. Every step she took came with some new change she had to adjust to; her centre of gravity lowered as she became more bottom-heavy, even her height was shifting. Thankfully, even as her muscles diminished, they didn't disappear entirely.
A thousand tiny changes were taking her; she couldn’t even keep track of them all, especially when the big ones kept distracting her. She winced, pressing her body against a smooth stone and held her breath as a jogger passed by. She could feel herself being pushed back as her chest grew even more.
This was getting ridiculous; she was going from one extreme to the other! If her breasts and butt got much curvier, she was going to struggle to walk properly. It already felt like her hips were swaying a ridiculous amount; the natural weight of her ass cheeks made walking without it impossible.
A selfish part of him had wanted to be a guy just for the ease; no dealing with bras or back pain. Now she would have given his left tit for some support, literally, maybe if it wouldn’t make her even more unbalanced. Finally, she made it to the car. Luckily, the parking lot was abandoned, but it still felt humiliating to run across it desperately clutching at her own chest to try and keep them from bouncing.
She was so close, and then her swim trunks slipped down her smooth thighs, and she went fumbling to the ground. Her hopes that the new breasts would cushion the fall were quickly dashed; turns out, all that extra sensitivity just made them hurt all the more when they hit the concrete. Luckily, the fall wasn’t bad, and the ache quickly faded, but she was keenly aware that she was lying, basically naked, across the ground.
“God dammit.” She hissed, quickly getting to her feet and pulled the drawstrings tighter. Making sure the waistband was over her wide hips and more around her waist this time as an extra precaution, then made a mad dash to the car and practically fell into the back seat.
“I can’t believe I made it…” She breathed, trying to catch her breath. Breathing felt so odd now, with this extra weight on her chest. Experimentally, Vanessa rolled onto her back and watched her new tits rise and fall. She felt hyperaware of her new body in a way she hadn't after the first change. Her skin seemed more sensitive; she could feel the tickle of the seat fabric tickling her breasts and thighs. Was that because of the rapid transformation, or did women just have sensitive skin?
“Well, at least I know I’m hot as both sexes.” She gave a dramatic sigh and looked over the backseat.
The shirt she’d worn on the way over was lying there, and she held it up with a scoff; no way was it fitting on her with this body.
“I guess I’d better get out of here and hope no cops pull me over for driving topless.”
She sat up, ready to awkwardly climb over into the front seat, when she saw it. A woman’s bathing suit was sitting on the passenger seat, along with a note.
‘Vance, this is here just in case. You’re showing all the signs, so I thought I’d provide. Hopefully, you won't need it! - Jim’
On the one hand, it was irritating knowing he was right. This was an ‘I told you so’ gift if ever there was one. It was sweet, though, Vanessa couldn’t be too annoyed with him. At least not until she held up the swim shirt and frowned. It wasn’t a bikini, at least, more like a sports bra. Even so, it was way too small. There was barely enough fabric to cover a quarter of her boobs. Her chest was so large it would practically spill out of the shirt. She may as well tie two napkins to strings and wear that!
“What size is this?” She said, checking the tag, “Double D? How is this a double D? What the hell is my cup size then?”
In movies and books, they always acted like double Ds were these huge mountains, like the ones on her chest. Apparently, she and everybody else were greatly mistaken.
“It’s better than nothing, I suppose…”
The grateful feelings she had toward Jim were slowly eroding, thanks to the top, they disappeared entirely when she tried to squeeze into the swim shorts he’d given her. The shorts were clearly designed for a woman of more average height. Vanessa had lost a few inches changing from man to woman, but she was still at least six feet, which meant the bottoms were way too short. They only barely covered the top of her thigh, for God's sake.
After a few minutes of awkwardly squeezing herself into the shorts and hefting her new breasts into the cups, Vanessa was at least decent. Well, as decent as somebody with her body squeezed into these clothes could be. She got into the front seat and sighed, hands on the keys. As much as she wanted to avoid the embarrassment and Jim’s smug face, she couldn’t just leave without him. Not after he’d tried to be so nice; emphasis on tried.
She looked out the car window down toward the beach, ignoring the pale reflection in the glass. She would look at herself properly later; right now, she was focused on Jim. He was walking out of the water, back toward his bag. She reached into the glovebox, grabbed her phone, and hit speed dial.
“Vance?” Jim answered. “Where are you?”
Vanessa hesitated and ran a hand over her throat, feeling the gentle, smooth curve where her Adam’s apple had been only a few minutes ago; what a difference an hour could make.
“Hello? Are you there?”
“Yeah, I am.”
“Oh.”
Vanessa didn’t even have to say anything more; there was understanding in his voice right away.
“I’m at the car…thanks for the clothes by the way.”
“Of course. Um, did you want to leave?”
“Yes.” She replied desperately, “And I am going to need something else to wear soon.”
Vanessa glanced down at her cleavage and swallowed.
“You didn’t get my sizing quite right.”
