Catalyst for Romance [Agender to Woman TG]

Commissioned by Cooolooo

By TheSpiralledEye

In the near distant future, humanity has taken to the stars. On the moon of Titan, everybody is born genderless and only upon taking a catalyst on their 20th birthday do they gain a gender. Sam has always dreamed of being male, while his best friend Valerie wants the opposite. But when their catalysts get mixed up, sparks fly, and secret feelings get revealed. 

~

Sam sped along the highway, watching the hazy yellow sky over Titan slowly darken as night fell. Valerie was in the passenger seat, their long blonde hair flowing behind them. In their lap sat a small, innocuous box; maybe somebody from another colony would discount it, but the tiny circle of stars on the front symbolised so much to the people of Titan. 

The colony had been established almost a hundred years ago now. The colony ship had arrived in a state of disarray; half the colonists were dead from an outbreak of disease on the long journey through the stars. It had quickly come to the attention of their scientists that there wasn't enough genetic diversity to correctly populate the new moon since only a handful of women had survived. Luckily, one of the survivors had been a brilliant geneticist and discovered a workaround. 

The colonists had been made mono-gendered, physiologically identical to one another, and then drew straws to pick a new sex. With an equal number of men and women once more, the colony had been saved. The side effects, however, were that the first generation of Titan locals were all born the same: genderless. 

Even adaptable, the people of Titan adopted a new tradition: all people born here would grow up without a gender, then, at the age of twenty, after two decades of thought and experimentation, they would be able to pick whichever sex took their fancy and felt right. These days, there was no issue with population, so people were free to become whatever sex they pleased. 

Valerie and Sam had grown up hearing these stories, of course, and now, their time had come. Both came from a remote outpost on Titan, one of the few ranches that raised actual livestock rather than using cloned meat. Even when they went to their first year of college, they’d stuck together, and when it came time to choose their sex, they decided to skip the usual big party and head back home to transform in private. Sam’s parents were on a six month supply run to Earth, so they had the space entirely to themselves for the summer and then some. 

Sam had never been in doubt about who they were supposed to be; athletic, masculine, a lover of sports and all things physical. Sam was born to be male. Valerie had always been on the fence. As a child, they had constantly been changing their mind, at least until the start of last year when all of a sudden they had stood firm, female. They’d even started to grow their hair out for the occasion. 

They pulled up to the ranch just as the sun was setting, and Valerie carefully picked up the box as if it were made of glass. 

“Are you nervous?” They asked, and Sam chuckled.

“A little, but honestly, I don’t think it’s possible to be more nervous than that clerk. Did you see the way her hands were shaking as she put the phials in?”

Valerie giggled.

“Yeah, but it was her first day, and everybody had to start somewhere. I just don’t think she realised she would be holding somebody’s whole future in her hands.” 

“Well, what did she think she was going to be doing at the distribution centre?” Sam snorted. “Anyway, let’s go inside and change the entire course of our lives, shall we?”

Valerie laughed again and leaned on Sam’s shoulder; the blonde had been doing that a lot lately. Sam had no idea why Valerie had become so much more touchy feely in the last few months. They didn’t hate it or anything, but Sam wasn’t sure why their friend had suddenly changed so much. 

They took the elevator up to the house proper, and Velrie carefully placed the box down on the bench. All of a sudden, a strange feeling coiled in Sam’s gut. They’d been joking about it before, but it was true; their whole life was about to change. Tomorrow the red head would wake up with a penis where there had always been smooth skin. A few days later, Valerie’s breasts would grow in. It felt weird, like adulthood was suddenly crashing into them. Sexual organs and obvious differences…those were for adults who had their lives figured out. The fact that they would be one of them tomorrow almost didn’t feel right. 

Valerie was just about to open the box when Sam reached out and placed their hands over the top.

“Let’s go play tennis.”

“...What?”

“One last time, as the old us.”

“Sam, it’s dark out.”

“We have lights.”

Valerie shook their head and smiled.

“Okay, one last time as the old us. I suppose I should treasure being able to cream you before you put on all that extra muscle.”

The two friends headed back down, grabbing the racquets as they went. Tennis had always been a passion they shared, more Sam than Valerie but they had always been happy to indulge their friends' hobbies. They set up on the court and Valerie bounced the ball. 

“Ready?”

Sam knew she meant the ball, but he couldn’t help but mutter under his breath.

“I hope so.” 

Valerie served, and Sam’s mind went blank, just like it always did. There was nothing but the squeak of their shoes against the ground and the thwack of balls hitting racquets. Their nerves calmed, and after a while, the two of them stopped keeping score. From the outside, it probably felt silly, but Sam could sense how important this moment was. In a way, it was their last gasp of childhood. 

“Okay, I give in!” Valerie puffed, “I can’t keep up…”

“You gotta do more cardio.” Sam joked, “I could keep going for hours.”

“Well, you spend half your life lifting weights and playing.” Valerie rolled their eyes. “Come on, let’s go take our catalysts.”

Now that most of their extra nervous energy had been worked out, Sam felt nothing but excitement buzzing under their skin. Tomorrow, they would be a he; with more muscle and strength to boot. Their tennis game would be incredible. 

Valerie opened the box on the table to reveal two small vials, each with their name printed on the side. Sam took his and clinked it against Valerie’s like they were toasting champagne.

“To our new lives.”

“To our new lives!”

~

Sam’s eyes opened and immediately, there was something different; there was a sense of self that hadn’t been there before but it wasn't what the redhead had been expecting. She felt distinctly…not male. 

“I don’t feel male…”

Sam sat up and felt something strange between her legs. She ripped back the blankets and was met, not with a masculine cock but the exact opposite. A small mound of hair, with dark pink folds in the middle. No wonder she didn’t feel like a ‘he’! 

“What the hell!”

Even her voice sounded different; it wasn't fully feminine yet, but it was definitely higher. 

A knock at the door made her jump, and she quickly covered up her lower half before the door creaked open.

“Sam?”

“Valerie?”

“Uh, I think Val would be more appropriate.”
Val stuck his head in the door and Sam’s heart ached with jealousy; there was a hardness to Val’s face, a squareness to his jaw that was undeniable. The fact that he was wearing nothing but boxers was another dead giveaway. Even through the loose fabric, Sam could see the outline of something that hadn’t been there yesterday. 

“I think maybe the person at the clinic mislabeled the vials.”

“Ya think!?”

“Hey, take it easy. Maybe they can fix it?”

“Have you ever heard of somebody switching sex after taking their catalyst?”

“Well, no, but back on old Earth, people used to have surgery, right? I am sure there is a way to set it right.”

Sam felt her eyes start to burn in frustration and quickly wiped at them, but it was futile. Tears spilled over her now long lashes, and she felt a lump form in her throat.

“Oh, Sammy…”

“Sam!” She corrected, “I’m Sam, and I am male! Even if all the damn estrogen in me right now and it’s making me act like a little girl.”

“Hey…” Val sat down at the edge of the bed and grasped her shoulder. “You’re not fully changed yet, just take your time, I am sure in a few days you’ll get used to the idea of being female.”

“You’re right.” Sam realised, “I’m not fully changed yet, there is still time! Maybe I can counteract the catalyst!”

“Uh, that’s not what I-”

“I’ll go in hard on the training, get the testosterone and adrenaline pumping!”

“I don’t think that’s how it works.”

Sam ignored him and jumped out of bed, forgetting his nakedness for a moment before Val cleared his throat in discomfort.

“Sorry!” 

Sam quickly put on a pair of boxers and shorts; luckily, his chest hadn't started to develop yet, and he wasn't about to give it the chance. She headed straight for the deck where her weights were and started pumping. She grinned; she was still lifting her usual dumbbells with no problem, so maybe she really could nip this in the bud.

“Sam, at least have some food first.” Val insisted, “Come on, I’ll make you something.”

“Eggs, protein, carbs.” Sam grunted out, “I want to be here all day.”

“You know that’s dangerous.”

Sam gritted her teeth. She hated how gentle Val was with her, like she was some delicate flower—like she was a woman. He wasn't even being as touchy-feely anymore; in fact, he seemed to be trying as hard as possible not to touch her, and for some reason, that only made her angrier. 

“How are you so calm about this!?” Sam cried, throwing down the dumbbell and wincing as it chipped the floor. “Aren’t you upset you’re a man?”

Val rubbed at the back of his neck awkwardly; the long blonde hair there was still a reminder of the original plan.

“Not really.” He said after a moment, “I was okay with either, really. And, is it that big a deal? I mean, you always said you found feminine people more attractive anyway.”

“Yeah, as in I was attracted to them, not that I wanted to be one.” 

Val pressed his lips together and looked away for a moment. 

“So…you couldn’t, ah, never mind. Look, I am going to make you some breakfast. You’ll feel better after you’ve eaten.”

Sam rolled her eyes and went back to her weights. She bent down to grab the one she had thrown and felt a strange shift in her centre of gravity; there was a weight on her chest that hadn’t been there before. She bit down on her lip in frustration, ignoring the weight and the fullness of the lip under her teeth. She refused to acknowledge either of them. She didn’t care what that vial said, or what her body looked like, she was male, and she was going to prove it. 

~

That first day passed in a blur of work outs, runs and disapproving looks from Val. By the time the sun had set, Sam was exhausted and practically fell asleep the second she hit the pillow. When she woke the next morning, the sun was high in the sky and her chest was aching after a night sleeping flat on it. 

As soon as she sat up she could feel the extra weight there; the soft supple flesh of breasts that was already growing. A little voice in her head told Sam to calm down and accept what was happening. Deep down she knew the catalyst couldn’t be reversed by acting a certain way but right now she wasn’t ready to face that, she needed to prove herself, and the science, wrong. 

So she got to her feet, stretched a pair of sports shorts over her ever-widening hips and stepped out into the kitchen, where Val was waiting. He was even more masculine now. His body had taken on more hard edges, and he’d even cut his hair short. Sam felt her body ache with jealousy; at least, that’s what she assumed the squeezing sensation in her chest was. Val’s face immediately turned red when she walked in.

“Uh, Sam, I think you need to put a shirt on.”

“Why? Guys can walk around shirtless in their own home, can’t they?”

“Yeah, but you’re not…” Val’s voice trailed off as Sam fixed him with a hard stare.

“Yeah, that’s what I thought,” Sam said harshly. “Now, I was thinking we should celebrate since we’re not having a party. Want a beer? I will order some for delivery tonight.”

“You hate beer.”

“No, I don’t.” Sam lied.

The truth was, after the first night they had ever gotten drunk as teens, she couldn’t stand the hoppy taste of beer. But beer was a ‘mans’ drink and goddamn, it was a man. She’d learn to like it. 

Val still wasn't looking at her; he was blushing like a bride, and Sam scoffed. If anything, that was proof their genders should be switched. Val had always been the softer, more sensitive, and emotionally mature of the two of them. 

“Come on, man. Look at me.”

“Sam…”

“No! Look. At. Me. We’re just two bros here; there is nothing weird about me being shirtless.”

Val scoffed and rolled his eyes.

“You’re acting like an ass.”

“Yeah, well, guys are supposed to be macho, right? All that testosterone pumping! If you were a real guy, you’d understand.”

Sam could see Vals’ patience getting thin, and guilt started to worm its way through her, but she discounted it. Yeah, she was being a bit of an asshole but she just…had to prove she was a man. Even if her body disagreed, if she could walk the walk and talk the talk, maybe, just maybe, everything would be alright. Val’s hands curled into a fist, and Sam braced herself: a fight! That was about the manliest thing she could do right now. But of course, Val let out a frustrated breath and shook his head.

“I get it, you’re frustrated, but don’t take it out on me. You’re not the only person struggling right now. Just call the damn Catalyst Centre and get it fixed rather than lashing out.”

He stormed out of the room, and Sam felt her frustration melt away into pure guilt. She knew she was being unfair to Val, but for some reason, the fact that he was adjusting so well rubbed her the wrong way. It just didn’t seem fair; how could Val care so little about the direction of his life being irrevocably changed? 

Sam let out a deep sigh and felt her chest rise and fall. She grimaced down at the pair of tits resting on her chest; they had already gone up half a cup size since she woke up. Who knows when they would stop growing. Once they were done, paired with her wide hips, nobody would ever mistake her for a man, even if she kept her short hair. 

“Fine.” She hissed and reached for the wall console.

The video call took a moment to connect before the same woman from the other day appeared. The second she saw Sam, the blood drained from her face, only to immediately flush back in when she realised Sam was topless.

“Oh, um, hello. What can I do for you?”

“I think you know exactly what you can do,” Sam said, temper rising again. “You can fix my catalyst! You gave us the wrong ones!”

“O-oh dear.”

“Yeah, so, how quickly can you get me a new one?”

“A n-new one?”

“Yeah, nobody ever talks about it, but there must be a way to fix this, right?”

Sam felt the tiny kernel of hope she’d held onto slowly disintegrate as she looked at the woman’s face. There was panic there; she knew there was nothing that could be done and was terrified to say it because she’d get in trouble for the mistake. Somehow, that just made Sam even angrier; her entire life had been ruined, and this woman was worried about her job?

Blood pounded in her ears so loudly that Sam barely heard the woman explain that there was nothing to be done. Down the line, perhaps she could travel to a hospital on another moon for surgery, but once a catalyst had settled, there was no reversing it. After a while, Sam just hung up. She was furious, but it was a cold fury. She didn't want to yell at a manager right now or get that lady fired; neither of those things would make her a man. 

Sam grit her teeth; her parents would be home near the end of the summer and were expecting to meet their son. She was going to do everything to use the power of sheer stubbornness to make sure that happened. 

~

All their lives, the children of Titan were told about taking their catalyst one day. It was built up as this beautiful thing, a metamorphosis that showed the world all the inner growth they had done. Over a few weeks, your body would shift, and you would become your true self; and emerge an adult, in every sense of the word. 

Sam felt like a caterpillar who had always dreamed of becoming a butterfly, only to emerge from her cocoon a moth. Every change only made her feel less comfortable. When she got up the next morning and rushed out to start lifting, she cursed as her hand hit the doorknob. It had never done that before. 

“Ow…”

She’d walked the same way as always, but instead of glancing past, her palm had smacked right into it. 

“Am I…shorter?”

She reached into her cupboard and pulled out her favourite pair of jeans, quickly slipping them on. They were no longer a perfect fit. In fact, she struggled to even get them over her ass and hips. The fabric strained and they were an inch too long in the legs now, leaving them baggy in places they should have been straight and stretched in others. The cut was all wrong; and she hadn’t even finished transforming yet. 

Sam had never been a vain person, but there was something so upsetting about her favourite jeans no longer fitting right. She grabbed for her favourite shirt; a band tee she’d picked up a few years ago at her first concert. She and Val had gone together; it had been their first time at an off-world music festival. They’d gotten so drunk, and their ears had rung for weeks afterwards; it was one of her most cherished memories. 

She stared down hard at the shirt in her hands, as if trying to will it to fit just as perfectly as it always had. Then pulled it over her head and stretched it down. Immediately, something felt off, the slope of her shoulders was different, the image on the front slightly warped as it pressed against her burgeoning chest, and the edges hung loose as her waist now cinched in by a few inches. She was hardly fully figured yet, but it was happening. One more cup size and this shirt would stretch beyond repair. 

Sam stared at herself in the mirror with a mixture of disgust and frustration: she was in her favourite outfit for the last time. She was never going to wear these again, she’d have to get a whole new wardrobe. Still, her eyes couldn’t help but focus on all the little feminine details and appreciate them. She was almost cute. 

“I don’t want to be cute.” She reminded herself. “I want to be handsome and…masculine.”

In annoyance, she ripped the clothes off and chose a loser pair of shirts, followed by the tightest fitting shirt she could find. She couldn’t do much about her hips, but she’d squash these breasts before they could grow. 

Val was already up when she finally emerged. He was leaning over the kitchen bench, one hand on his hip, wearing just his pajama pants and rubbing at his now short, blonde hair. 

“You cut it?”

“Hm, yeah? Long hair is a pain, honestly. All that washing.”

Val turned and grinned, it was the same grin as always: playful, slightly teasing, but for some reason it made Sam’s mouth dry. His face had changed so subtly, but it somehow made his smile all the more charming. The fact that his square hips and broad shoulders were on full display didn’t hurt. Envy burned in her gut, and…something else she couldn’t quite place. A strange heat and weight low down in her stomach. 

“Well, I am keeping mine short.”

“Loads of women do.”

“What women do isn't important, but almost all men do, that’s my point.”

Val let out a deep sigh. 

“You’re going to have to look in a mirror eventually.” 

“Hmpf.”

Val snickered and Sam watched as his cheeks turned slightly pink; it made that feeling in her lower stomach stronger. 

“What?”

“Oh n-nothing.” Val said a little too quickly. 

“Spit it out.”

Val rubbed at the back of his neck bashfully. 

“I was just thinking, you’re kinda cute when you pout like that.”

Cute. Pout. 

“I do not pout!” 

“Tell that to your bottom lip right now.”

Sam forced her face to go straight, which only made Val laugh harder.

“I am glad you think my suffering is funny.”

Instantly, the laughter stopped, and Val turned serious.

“Hey, I didn’t mean…I’m sorry.”

“Whatever, I am going to try and save my muscle mass and work out.”

“Again? You’ve done it every day, usually, you only lift once or twice a week tops.”

Sam went to bite her lip and then stopped herself. Men lifted weights and went to the gym daily. It was a manly thing to do, if she could just keep acting manly and avoid all things feminine, maybe she could pass. That’s all she wanted right now. She didn’t bother explaining herself to Val, instead, she breezed past and moved to the weight room, ready to pick up where she left off when a hand grabbed her wrist. 

“I mean it, you need to take it easy or you’re going to hurt yourself.”

He was right, that made Sam feel even more pissed off. 

“Fine. I’ll go for a run instead.” 

Val rolled his eyes.

“Not exactly my idea of taking it easy, but fine.” He sighed, “I’m going to go help out the farm hands. Your parents made me promise since you always forget.”

“Oh…shit.”

She had totally forgotten, technically she was supposed to be overseeing the ranch while they were away. It must have shown on her face because Val rolled his eyes fondly.

“Go run. I’ll go check on things. I have been doing your chores since we were kids.”

“You’re just better at them than me.”

“How convenient.”

Sam gave him a wave and headed out the door for a few minutes there. Everything had felt right, even if their banter had a strange edge. It wasn’t bad, just different in a way she couldn’t quite put her finger on. The moment she stepped outside and started running, though, she was reminded of all the changes her new body was going through. Even in the tight shirt, she could feel the heft of her breasts moving as she ran and the burn of her muscles trying to keep pace. Some women were naturally muscular; she hadn’t been so fortunate. 

Still, Sam forced herself to keep going. It was foolish, but a part of her thought was that maybe if she ran fast or far enough, she could escape the transformation entirely.

~

“Ow!”

Sam rubbed at her hip where it had run into the table. Her side was already sore enough from poking into her mattress all night, now it throbbed. She had tried to sleep on her stomach to no avail and ended up on her side. Her hips were widening each night until the bones poked against her skin in her sleep. 

“Why would anybody want to be female?” She muttered, “It’s so much trouble.”

Another day, another look in the mirror and another huff of annoyance. More curves, more softness. 

“Seriously, what’s the point of these?” She groaned, hefting up her breasts in her palms.

The touch of skin against skin made butterflies dance in her stomach, and she quickly dropped them, taken aback by just how sensitive they were. A moment later, curiosity curled in her mind, and she reached up, brushing a finger lightly over her new nipple and shivering.

“Okay, so they’re not all bad.” She muttered, before quickly adding, “I still don’t want them, though!”

She stepped out of her room and was once again met with Val, looking even more male. His face went red as they ate, and Sam stared him down, almost daring him to say something about her bare chest.

“Have you considered trying a bra, at least?” Val said finally. “I can hear you wincing all the time. Is your back hurting?”

“Yeah, so? It’s probably because I keep getting shorter.” Sam replied bitterly, but Val shook his head.

“It’s your breasts; the weight is putting pressure on your spine. I looked up info when I thought I was going to be-uh, never mind. The point is, I have some girls' clothes, including a bra. If you want to try it.”

Sam screwed up her nose, ready to tell him exactly where he could stuff the damn bra when his back twinged and it must have shown on her face. 

“Just try it?” Val asked gently, “For me?”

His face was so sincere, like an innocent puppy. Sam had snapped at him quite a bit lately, if it would get him to shut up maybe she could at least try it. 

“Fine.”

She instantly regretted her decision when Val produced the least practical looking bra she’d ever seen. It was dark, velvet purple, with flowery lace coating the front and large, stiff cups. It looked more like lingerie than your everyday bra. Val’s face was red as he handed it over.

“I bought it thinking it would be nice to feel pretty in my new body.” He explained lamely. “But it’s got a good underwire, so you should have plenty of support.”

“Whatever.”

It took a bit of fiddling to even put the damn thing on. Hefting each of her breasts into the cup was simple enough, but Sam swore those hooks were made much smaller than necessary. Once it was on, she felt the difference immediately. 

Sam didn't want to admit it, but it felt nice. The soft cups held her breasts and even though it was too small, and her tits spilled over the edges it was infinitely more comfortable than being fully naked. She turned on the spot, admiring her breasts in the mirror. They looked lovely being held in that bra and they accentuated her figure-wait, that was the opposite of what she wanted, right?

Sam caught herself softly smiling at her reflection and frowned in disgust. She wasn’t supposed to be enjoying this. Sam ripped the bra off in annoyance, trying not to pay attention to the hang in her chest and the pain in her spine as the weight settled once more. The door slammed as she stormed out and Val practically jumped out of his skin as she stuffed the bra against his chest.

“I hate it.”

She didn’t give him a chance to say anything else. 

~

The dumbbell bar felt cold in Sam’s palm. She knew she shouldn’t have listened to Val. A few days break from lifting and she could already feel the muscle she’d lost and fat she’d gained. Not that she was overweight at all; no, it was just that she was gaining all the weight in very specific places. No matter how diligent she was about sleeping on her stomach to crush them, or how tightly she wrapped her chest, her breasts refused to stop growing. 

They hung under her now as she bent over to grip the dumbbell bar with both arms, ready to lift. She squatted down, branching her legs and feeling her heart thunder in her chest. She had been able to lift this with a bit of effort a few weeks ago, it shouldn’t be a problem now. She’d been doing small lifts even after her change. 

Sam sucked in a breath, tightened her grip and lifted, Straining against the weight and feeling her arms burn. The dumbbell didn't even get half an inch off the ground before the bar slipped from her fingers, and she was bent over double panting.

“Come on…”

She tried again and again, but it was useless. She might as well be trying to lift an elephant; she simply wasn’t strong enough to lift the weights. This was supposed to be a one-armed weight, but even using two, it was a struggle to get it off the ground. Sam knew the smart thing would be to unscrew the rings to make the whole thing lighter, but she refused. At the very least, she had to be able to lift it back up onto the rack! 

Eventually, she managed to lift it off the floor using both hands; her whole body was bent double, and she shuffled across the floor with her breath coming in short, sharp bursts. When she finally laid the dumbbell back down she collapsed back onto the floor, straight on her cushioned ass breathing heavily. With each gasp, she could feel the rise and fall of her chest. Her traitorous, voluptuous chest. She glared down at it, trying to will it away, but of course, that didn’t do any good. 

“Fine, if that’s how you’re going to be.”

Sam reluctantly reached for one of the smaller dumbbells. This time, she managed to lift it with just a single hand, but it wasn't easy. Sam wasn't stupid; she knew it was still too heavy for her, but it was humiliating enough having to go down a weight class at all, so she refused to go down more than one. She did a single lift and felt her now ultra-feminine arm scream in protest. 

“Why couldn’t I have at least been a tomboy?” She muttered, blowing her red bangs out of her face. 

Her hair had been growing at an accelerated rate, so now chopping off the extra was part of her morning routine. The most irritating part was that even with the pixie cut, her face still looked ultra-feminine, not even androgynous. Fate was laughing at her. 

“Sammy, stop that.”

Sam didn't turn, just kept staring ahead while trying to lift.

“Stop…what?” She hissed through clenched teeth. 

“I can see from here that’s too heavy for you, if you insist on lifting, at least do it safely.”

Val reached over her shoulder and easily picked up the starting dumbbell, giving it a little toss for emphasis. Sam wanted to bite her lip, but her teeth were currently grinding against each other. It was so unfair! Did Val even realise just how much he was taunting her? Val waited a moment before putting down the weight when it became clear Sam wasn’t going to take it. 

“How about I help you then?” He offered, and that was the last straw, this was too emasculating. 

“Let’s play tennis instead.” She hissed, putting the weight down on the floor and hoping Val couldn’t tell it was because her arm was too tired to put it back on the rack.

“Okay, but don’t you want to rest your arm first?”

“It’s a deliberate handicap.” She lied, “I’ve always thrashed you at tennis, now you’ll stand a chance.”

The words came out harsher than she intended; she meant it as a fun barb but instead it came out pointed. It was true, she had always been better at tennis than Val but he still won from time to time and was plenty good enough to play with her without the need of a handicap. Val’s eyes narrowed slightly and Sam let out a frustrated sigh.

“Sorry, that was uncalled for, I’ll go get a drink, stretch, and then we’ll play fair and square.”

“Sounds good.” Val smiled.

Sam could feel her palms sweating slightly. The truth was, she wanted the excuse of a sore arm just in case Val did somehow win. She went to the fridge and grabbed a random drink without paying attention and downed it: orange juice. She hated orange juice, but she stomached it anyway. 

She was going to win, she was going to prove this ultra feminine body wasn’t going to stop her. She adjusted the wrap around her breasts, pulling it as tight as it could go, even so, her breasts were still spilling over the edges. 

“Ready?” Val called from the court.

“Ready.”

Sam jogged back to the court and grabbed a racquet, giving it a few practice swings and immediately wincing as her breasts got in the way. She must have been close to an F cup now, the wrap wasn't doing anything to hide them; it was basically a glorified bra. She looked across the court at Val, who looked like he was going to say something before thinking better of it. He bounced the ball and served.

Sam dashed across the court and scooped the ball up just in time, sending it flying over the net. Her lungs burned with the exertion but adrenaline made up for it. For the first time in weeks, Sam felt a smile form on her face. The same sense of peace the sport had always given flowed over her and she focused on the game, mind blank.

For a few back and forths, all was well, she scored, then again. She was winning! But then she began to notice things; like the way her chest moved despite the wrap, the way her arm slammed into her tits on a big swing and how the strands of hair she’d missed this morning felt on the back of her neck. Small distractions that ended up costing her a point. 

She tried to keep up, but it was impossible. Her strength and stamina had been sapped and Vals’ increased. She watched him across the court, effortlessly catching volleys that had her gasping for breath. His lean, muscular frame moved gracefully while she was anything but. 

Her mouth went dry, but not because she was gasping for air. Something about his body started to distract her as well. Once she started watching him with envy, she couldn’t stop, and a strange tickling sensation formed in his stomach—like the brushing of butterfly wings. She swallowed and tried to hit the next volley, only for it to skim right past her.

“Want to take a break?” Val called.

Sam didn’t answer; she just grabbed the ball and served again. Val hit it back easily, and the ball spun as it hit the ground, spinning off to the other side of the court. Sam ran, but as she leaned down to try and scoop it just in time there was a snapping sensation and suddenly her tits were in the way. The rap had snapped, and the ball bounced past her. Not that she could see much of the ground now. 

Immediately, she was overwhelmed with the instinct to cover herself, but Sam stopped it. The whole reason she was doing this was to try and prove she was male. A male chest was nothing to be hidden away. Sure she had these giant tits now, but that would change soon one way or another. 

With some difficulty, she reached down and grabbed the ball, ready to serve again. This time, Val didn't hit it back; instead, it wooshed past him as his racquet hit the ground.

“Uh S-sam?”

“Yeah, what is it?” She asked, hands on her hips.

“You’re, uh, chest.”

“What about it?”

“Um…” Val swallowed, and Sam hit him with the best glare she could muster. “It’s just that, isn’t it going to be hard to play without any…support?”

“Do you need support?”

“No but-”

“Then I don’t either. Come on, let’s keep going.”

I’m a man, Sam thought to herself, I refuse to cover myself up.

The game continued, but immediately, Sam realised her disadvantage was worse. She’d struggle to run before but with her tits out it was nearly impossible. They bounced wildly with every step, and each time, she felt a small twinge of pain. The urge to hold them in place was strong, but Sam was steadfast. She was going to ignore them, even when her body made it practically impossible. 

With each point she lost, Sam felt her determination getting stronger. She would claw her way back to victory; she had to. It didn't help that Val was playing terribly; he could barely stand to look at her, and his face was red. And yet, he kept winning, simply because of his speed and strength advantage. An advantage he never even wanted, an advantage that should have been hers. 

“Would you just look at me?” She yelled eventually as her temper reached a fever pitch. 

“I am looking at you.” Val lied, staring right past her.

“You are not! You’re treating me like a woman!”
“You are a woman!” Val threw up his arms, “God, I can’t stare at your chest when it's bouncing around like that! Come on, it makes me feel like a perv.”

“I keep telling you to treat me like you always did, like I’m a guy-”

“But you’re not a guy! You’re a woman, and a curvy one at that, who desperately needs a bra on right now!”

Sam grit her teeth.

“You just don’t want me to win.”

“Sammy.”
“Come on, let’s keep going. If you have any respect for me, you won’t throw in the towel.”

Val pressed his lips together and sighed before picking up his racquet again. 

“Alright.”

What was he supposed to do? Val had heard about being between a rock and a hard place; he was between something soft and a hard place. And somehow, that was worse. Val bit his lip; it was hard to control himself. At least when he’d been attracted to somebody in the past, he could hide it. This tennis match was a triple threat: willing himself not to get hard, trying not to stare and needing to win to make Sam see the light. 

He served and watched in shock as the ball bounced right past Sam. She ran for it, her breasts bouncing wildly without any support, but it was useless. The combination of losing some muscle and a few inches in height made it impossible for her to reach the other side of the court in time. 

“Just…give me five.” Sam panted, her spunky red hair was plastered to her skull with sweat, and her skin was glistening. 

“Why don’t I get you a towel?” Val said croakily, trying hard not to stare.

“Why? To cover me up?” Sam snapped, “Because my boobs are too female!?”

“Because you’re sweaty and probably feel gross, jeez.”

Sam’s face was bright red, and her eyes darted from his face to the ground as Val handed over the towel. 

“So are you.” She muttered, snatching the towel, “But I guess that’s fine since you’re a guy, isn’t it? Guys get to be all handsome and glistening after the gym and everybody thinks it’s so hot…”

“You think I’m hot?”

Val spoke before he could think, and then his own face was turning red. 

“What, no! I mean, well, objectively speaking, like, you’ve got a lot of masculine attributes that make you well…attractive but that’s not…shut up!”

“...None of that was a proper sentence.”

“You’re not a proper sentence!”

For a moment, there was silence, then Val couldn’t hold it back any more. He burst into laughter. Sam tried to hold back, but eventually she joined him and they were both bent double. 

“What sort of a comeback is that?” Val chuckled, wiping a tear from the corner of his eye. 

“I don’t know, I was flustered, okay?”

“Flustered?”

“Yeah, don’t read into it or anything.” 

Sam refused to meet his eyes, and Val swallowed; this felt like the right moment. It wasn’t at all what they had been imagining in the months leading up to their change, but it was the best shot he was going to get.

“What if I like that?”

“Me being flustered.”

“Yeah…what if you fluster me too.” 

His face couldn't get any redder; that had sounded so much smoother in his head! Sam sighed, her breasts rising and falling dramatically.

“It’s just this body, isn't it?” She muttered, “All I am is tits and ass to you now.”

“No! Sammy, that’s not true. I’ve wanted to be with you for years!”

She gasped sharply, and Val’s words caught up with him. Shit. Sam’s eyes searched his face.

“You…really mean that?”

“It’s why I wanted to be female. You seemed to set on being a guy, so I figured…whatever option you might be interested in…I’d pick.” 

“You chose your sex…because of me?”

“Like I said, I didn't mind what I got, so it was an easy choice really.”

Sam shook her head and Val felt his heart sink.

“It’s fine.” He said, clearing his throat. “I don’t expect you to feel the same way or anything.”

“No, it’s not that. I just can’t believe you would do that for me.” 

Val fixed Sam with the most sincere look he could.

“I’d do just about anything for you, Sammy, that’s why I have been trying to get you to take it easy, I don’t want you to hurt yourself. I won’t lie; you running around topless while having the world's most amazing rack doesn’t help. You’re more than tits and ass, but you know, I’m not about to pretend they’re a downside to this.”

Sam snickered.

“They are pretty nice, I guess.” 

She hefted them up for emphasis and Val had to turn away.

“God, give me strength.”

“You like that?” Sam teased before bursting into giggles. “Just joking, I can see you do.”

Val would have blushed, but the blood in his body had other places to be. 

“Come on, you can’t blame me for that,” he flirted. “If I didn’t know any better, little lady, I’d say you were flirting with me.”

“Who are you calling little?” Sammy giggled, hefting up her breasts again to rest against his chest. 

“Of course, my apologies.”

Sam was so close now; their lips were only an inch apart.

“Sammy?”

“Yeah?”

“What is this?”

“I think this is a girl finally letting go of her need to be in control.” She whispered.

Val could feel her hot breath on his lips and seized the moment to surge forward. Their lips met, and the rest of the world faded away. It was better than he had imagined; it didn't matter that he was a man and Sam was a woman. It was just the two of them, finally coming together, and that’s all he’d ever wanted.

~

Sam’s whole body was coming alive. For the first time since her change, she allowed herself to revel in all the new sensations it gave her. She enjoyed the way the skin around her nipples tightened as they got hard, the way her ass cheeks went taut with excitement as Val’s hands brushed against them. The touch was almost feather light, like he was asking permission. 

She’d spent these last few weeks trying to be in control, trying to change her fate. Now that she was finally surrendering to it, it felt so good. With the acceptance of her new female self, she expected to feel a wave of submissiveness wash over her, but instead, it was just the opposite. Instead of tilting her head back and letting Val take the lead, she pushed against him. 

His mouth opened to her, and their tongues danced together. Val let out a moan and Sam swallowed up the sound as her hands threaded into his hair and used it to pull him close. Val’s touches got more bold, and he went from stroking up her sides to grabbing handfuls of her bubbly butt. Sam couldn’t help but squeal in delight from the mixture of pleasure and tickling the touch caused, and Val took the opportunity to scoop her into his arms, bridal style.

“Woah! If you drop me, you’re in trouble.”

“Don’t worry, I can handle it.”

Sam felt a giggle building up in her chest, and she let it go. The sound was so light and made her whole chest vibrate. When they got to the bedroom Sam felt Val’s arms tense around her and he looked down with a cocky grin. 

“Don’t you dare," she started, but it was too late. Val playfully threw her through the air, and Sam landed with a laugh, bouncing on the mattress. Her curves bounced, too. Then, just as they stopped, Val jumped down to join her and set them jiggling again. Sam kissed him breathlessly.

“You’re incorrigible.”

“I get to stare openly now, I need to get my fill.”

“C’mere, you horn dog.”

Sam pulled Val down onto the mattress and flipped their positions before grabbing hold of his waistband. In no time at all, they were both naked, and Sam sat back to admire her new lover's body. She’d been watching while they played, of course. She hadn’t wanted to admit, even to herself, how hot Val was. He was well muscled, with broad shoulders and a just discernible six pack. Sam ran her fingers over it, then up across the planes of his chest to the square of his jaw. 

Val’s Adam’s apple bobbed as she went, and she leaned in close, crushing her chest to his as she lowered herself down to kiss at his neck. He trembled under her touch, and Sam finally felt the control she’d been craving since taking her catalyst. She thought being a man meant power and control, but she’d been wrong; this was so much better. 

She nipped at the shell of Val’s ear and felt him gasp; her hand traced his hip and threatened to slide between his legs only to reverse at the last session, leaving him groaning with frustration. Sam could feel her own need growing; wetness was forming between her new folds that made her equal parts excited and nervous. It was one thing to know how sexual organs worked, another entirely to feel that burning need inside her. 

Vals’ hips bucked, and she felt the hardness there. His length was pressing against her, and she rolled her hips down on it, sliding up and down the length while drinking in the delicious sounds escaping Val’s throat. 

“Fuck, Sam…”

“Are you ready?”

“God, yes.”

Sam met Val’s eyes and gently reached between them, taking hold of his length and positioning him at her entrance. They were both virgins, it felt right to do this together. Sam rested her forehead against Val’s and took a deep breath before slowly inching down on his cock. Instantly, she was overwhelmed with sensation. Her inner walls stretched, and there was a slight twinge of pain as they grew accustomed to the girth, but it was quickly eclipsed by pleasure. 

It felt almost too good. Sam took things slow, but she wasn't sure if that was making things more torturous; there was so much and yet it wasn't enough. By the time she fully engulfed him, her whole body was tingling. Her clit pressed against the rough hair of his crotch and Sam gasped. Val’s hand reached up to cup her face. 

“Are you alright?”

“It’s…a lot.”

“I know…God, you feel so tight.”

Sam squeezed around him experimentally and felt Val’s hand shake. 

“Hnnng! Do that again.”

She did, this time adding an extra roll to her hips, and Val’s back arched. Sparks flew inside her; once she started, she couldn’t stop. Val’s hands reached up to cup her breasts, his thumbs brushed her nipples, and this time, Sam moaned.

“You like that?”

“Y-yeah.”

“Lean over, and I’ll do you one better.”

Sam obeyed and Val took her nipple in his mouth and began to gently suck in time with her hips. Sam shuddered and gasped, her hips picking up speed as they rose and fell. Val’s tongue pressed against her nipple, and she saw stars. Pleasure was coiling inside her passage and was threatening to overflow. 

The shallow thrusts were wonderful, but almost teasing. Val let go of her nipple to try and catch his breath as he started to pant, and Sam took the opportunity to straighten up. She leaned back and braced herself against his legs, rising and falling the full length of his cock. She could feel the tip slamming into her G spot each time, and the ecstasy continued to climb. 

“Oh God, you look so good!” Val groaned, bucking his hips up into her. “Your tits, holy shit they look so amazing.”

Sam’s back arched, and she let her head fall back and her eyes flutter closed. There was nothing but the feeling of being filled and stretched. Then she felt Val’s hands brush her nipples again, and orgasm rocked through her. She felt her inner walls squeeze tight around his cock and Val yelled something incomprehensible before emptying straight into her. 

Sam’s spine snapped back as she fell forwards again, Vals’ cock still inside her as they both took a moment to catch their breath. 

“That was incredible.” Val muttered after a while, “even better than I had been imagining with our roles reversed.”

Sam giggled.

“I’m glad for it; I am sure that was good for you…but I think I won out.”

“If you say so.” Val chuckled, kissing her temple and wrapping his arms around her. 

With a shudder, Sam finally dismounted, and they wrapped themselves up in the sheets. Sam placed her head on Val’s chest and listened to his heart pumping, and something fluttered in her chest.

“We’re going to end up married, aren’t we?”

“Woah, buy me dinner first.”

Sam just snorted.

“We both know it’s true.”

“Yeah…I’m okay with it.”

“Me too.”

Sam sat up slightly and placed a proper kiss on Val’s lips.

“I think I can get used to being your wife.”
