Sitting alone in a small cafe, Jack found himself checking his phone once again, trying to control his slight impatience as he took a sip from his coffee. He was waiting for his friend Kate, who wasn’t usually one to be late, and was just about to call her when finally he caught somebody waving at him from the corner of his eye, his shoulders finally relaxing. Kate entered the cafe with her usual slightly floaty steps. Although she looked human in shape, her plastic skin, moulded balloon-like hair complete with a smooth plastic ponytail that was a primitive approximation of the hairstyle, the visible seams running down her hands, and her painted-on facial features save for her thick, literally puffy lips, all came together to make it clear that she was a living blow-up doll, albeit a fashionably dressed one. She dressed light, with jeans and a t-shirt and a very thin jacket, enough that it wouldn’t weigh her down, but also enough that a stiff wind wouldn’t blow her off her feet. Although her features seemed artificial, her eyes had a certain shine of life to them, and she was as animated and expressive as an ordinary human.

Jack, on the other hand, was very much an ordinary human, down to his imperfect vision requiring glasses and his short brown hair cut cheaply and designed to stay out of the way. Ordinary was the best way to describe him, and it was no coincidence that his appearance was inconspicuous. That would perhaps change soon, along with a great many other things about him, no thanks to her influence. But before the ordinary and extraordinary could convene, a waitress stood in the way.

“Excuse me, we don’t usually serve dolls here…” A waitress nervously said, Kate’s plastic lips curling into a friendly smile. 

“Don’t worry, I’m with a friend.” She said, gesturing towards Jack, who raised his hand in acknowledgement. The waitress sighed and gave an apologetic look towards her.

“Sorry, I respect your lifestyle, it’s just that my boss insists dolls are lost sales, seeing as you, you know, can’t drink anything…” The waitress explained awkwardly.

“If he complains, tell him I bought two coffees.” Jack laughed it off. “Which is true, by the way. What took you so long?”

“It wasn’t my fault, okay? Well, okay, it was my fault, but still.” Kate said defensively. “My valve snagged while I was getting dressed and I didn’t notice until I was out the door. If David didn’t oversleep and find me draped over his doormat I probably would have missed you by another hour! I was gonna text you about it, but phones are hard enough even when I have working fingers.”

The waitress blushed at Kate’s casual explanation, scurrying off to serve another customer. Kate got a wry smile out of that, always enjoying the attention her body gave her. Her body squeaked slightly as she sat herself down, and again as she crossed her legs. Jack took a deep breath, then reached into his pocket and produced a tiny container with a single white pill inside of it, placing it down on the table in front of her.

“So I finally got it.” He said, feeling like he finally had a load off his chest. Kate whistled, then grinned.

“It sure took you long enough. I was shocked you hadn’t left your original body long behind by the time we started hanging out.” Kate chuckled, enjoying the slightly embarrassed look on Jack’s face. “So, should I start calling you a she now? I kinda felt like I should have been already, but I was waiting for the signal from you.”

“Let’s wait until I’ve used it. ” Jack said, his eyes constantly drifting to the transformative pill that would radically alter his body. There was nothing illegal or even particularly special about it, given how society had long gained total control over one’s body, and could change anybody into practically anything, as long as they were still humanoid, but still he couldn’t keep his eyes off of it.

“I hope you’re not planning on taking that thing right here.” Kate said playfully, Jack hastily stuffing it back into his pocket.

“No, of course not, I just, you know, wanted to tell you about it.” He said hurriedly.

“Just kidding, although I’ve known somebody who did that once.” She laughed. “But they were a real show-off. Well, I suppose you’ve put a lot of thought into this already, you don’t need to hear the speech from me. Anyway, what’re you doing first, just turning yourself into a girl? Physically, I mean.”

“I got the same as you.” Jack admitted bashfully, Kate’s eyes widening a little. “Hey, whatever happened to not being surprised?”

“No, I just figured you were the type to test the waters first.” She explained. “Hell, even I didn’t dive into the deep end first, and I’ve been all over the place.”

“You were still a furry when we met, weren’t you?” Jack recalled.

“Yeah, I kinda miss it, but on the other hand, I kinda don’t.” Kate said half-wistfully. “It was fun, but you wouldn’t believe how much hair gets all over the place. Plus, I picked a carnivore, and that got expensive fast. So, what made you wanna be a doll off the bat?”

“It just, you know, seemed like it’d be nice.” Jack said shyly, knowing that it was a hell of an understatement. Jack had been envious of Kate’s latex body for a long time and everything that came with it, but hadn’t had the bravery to step into her shoes, on top of his own complicated feelings on formally changing his gender. “So I figured I’m already totally changing my identity, why not go one step further? If I don’t like it I’ll just settle for being a girl.”

“Sounds like a plan!” Kate said enthusiastically, slapping him on the shoulder, although with her naturally feeble strength it merely bounced off of him. “So, have you picked a name yet?”

“I was thinking Reyna.” He said, Kate nodding approvingly.

“I like it! Hold on, let me just change my contact details for you…”

–

That night, Jack found himself staring at himself in the mirror, taking deep breaths and clenching the pill tight in his hand. He’d just finished cleaning up his kitchen and taking out the garbage after an extravagant delivery order of every unhealthy, guilty pleasure he could cram into his stomach, knowing that for as long as he were a doll, he, or rather she, wouldn’t be doing much eating. He also wouldn’t be doing much heavy lifting, and Kate had half-jokingly half-seriously advised him to take out the trash and get any last-minute furniture arrangement out of the way before transforming.

“Now or never.” He steeled himself, then downed the pill as quickly as possible, not giving himself any time for last-second hesitations. He had already stalled out on committing to starting his new life as a woman before, too scared to radically change his body and take upon the social consequences, even if it were his greatest desire. But as Kate had reassured him over and over, most of these fears were entirely self-inflicted, and there were many ready to welcome the new her. And for those who would be taken by surprise, well, the world had spent long enough with transformations being so freely available for all but the most stubborn to conquer any outdated stigmas.

He let out a huge breath he hadn’t known he had been holding, placing his palms on the bathroom counter. There, it was done! No turning back now and nothing to do but wait until it started to kick in, although he felt like he was forgetting something. Had he forgotten to take something out of his pockets… wait, clothes! He was still wearing clothes! He had been so preoccupied with actually doing it that he had forgotten the most basic step! He awkwardly pulled his shirt over his head and was about to clumsily undo his belt when he paused, seeing two slightly puffy nipples in the mirror before him. He leaned in, definitely able to tell that the area around them was a little soft, a little larger than usual. His chest already starting to look more slight, those were definitely two budding breasts already making their way onto the lettering chart, and his heart began to race in excitement. Already? He had expected to at least wait a few more minutes, but whatever! If he was growing breasts already, then he wondered when…

Jack grimaced at the sucking sensation between his legs, awkwardly undoing his belt and dropping his pants to see that his ever-present reminder of manhood was no longer so ever-present, and good riddance to it. It was like a weight off his back, no, her back to feel that unfamiliar sensation, that even if this transformation were to stop now at this awkward in-between point, she was finally on the outside the woman she was on the inside. Even thinking of herself as a she, a privilege she had refused to give herself until she forced herself to go through with swallowing this pill, filled her with elation.

By the time she had remembered what she was doing and got her pants off, her hips were already much curvier than before, her waist having sunk inwards as her chest grew and her shoulders narrowed to give her a distinctly hourglass figure. She ran her hands down two soft, hairless thighs, her body hair having totally faded by now, from her chest hair to her stubble. She’d also gotten a bit smaller, she realised with a quick laugh, a combination of many emotions forcing themselves to the surface as she brushed her rapidly growing hair out of her eyes, settling around her shoulders. Not too long, not too short, and most importantly, feminine. Her face went from masculine to boyish to feminine, her lips thickening and her eyelashes extending, her jaw narrowing and her cheeks softening and rounding a bit. Enough that she looked like a new woman, but not enough that it looked like she was staring at a total stranger. A sister, perhaps, in another world. 

With her gender transformed, Jack… no, Reyna eagerly explored her body, from her feminine curves to her steadily growing breasts, already around C-cups, to her bubble butt that seemed almost unnaturally round. Although, when was the rest of the transformation supposed to start? Reyna had just assumed that they would be simultaneous, not one after another. Perhaps that would be the part she’d have to wait longer for? Or worse, maybe she’d ordered the wrong pill by accident? Or she did one now, one later? That wasn’t how Kate had described it…

Before she could wonder further, her searching hands ran down her smooth belly and hit something hard, Reyna looking down to see what was unmistakably a sealed valve, a piece of hard plastic that signified her inflatable status. And from what she could feel, there was a patch of plastic around it, one that was rapidly spreading outwards. Reyna’s excitement grew as did the plastic patch until it began to wrap around her hips, a small indent on the side of each forming as she began to gain seam-lines down the outside and inside of her hips and thighs. She squeezed her thighs as the plastic spread down her legs, already feeling a bizarre divide in the sensation between her skin and her plastic, her eyes widening as her hands easily pushed inwards, revealing that she truly was hollow. The plastic reached her feet first, her knees buckling as the weight of her still mostly flesh and blood torso nearly caused her flimsy legs to collapse inward, but she thankfully lost enough weight to avoid that, and went from straining to remain upright to carefully trying to keep her balance on her new latex soles. Her breasts seemed to literally inflate as the plastic reached them, the already d-cups drooping initially then going from sagging to perking straight upwards, unnaturally round and firm, filling with air and going from quite large to almost the size of her head, blowing up like balloons. It was bigger than Reyna had been expecting, but she wouldn’t say that she disliked it.

She saw more seam-lines appear around her shoulders and under her armpits, pinching in slightly before transitioning into two perfectly smooth arms, creasing when she bent her elbows, as all they were now were two straight tubes filled with air. Thankfully she kept all of her fingers, knowing that some more extreme transformations went for a cheaper look that reduced their hands to mere mittens incapable of doing more than the most primitive of work. But although that had a certain allure, Reyna wanted to live a mostly normal life, and as such chose the simplest, safest doll form on the market. Finally her head was consumed, more seams appearing around the base of her neck, now able to feel it squash slightly whenever she looked down. As the plastic swept over her face, her lips puffed up a bit more, and her mouth lost all of its saliva,  perfectly plastic from her throat to her tongue. Her eyebrows and eyelashes sank inward and became clearly painted on, although they still were able to move and emote freely, the overall shape of her head mostly realistic. Her eyes in their sockets appeared painted at first, but those too moved just as they always had, although if one were to touch them, they would have seemed perfectly flat. 

Reyna’s mouth hung open at the sight of herself, a perfect plastic doll in every way, from her mouth to her puffy, inviting pussy that begged to be taken for a test run. Her body creased and squeaked with every movement, particularly when her thick thighs rubbed against each other. She felt literally empty, but figuratively she couldn’t be further from it. Everything about herself felt just right, although she lacked many of the sensations she had been used to as a human, and this would certainly take some getting used to. But her excitement was unquenchable, and perhaps despite her better judgement, all she could think about was, rather than stopping to get used to her body, was to take it for a test ride…

–

It was barely half an hour later that Reyna was walking down the street in her new body, enjoying the many looks she was being given in her tight black short-skirted dress and flat heels, both things she had bought roughly guessing her future proportions. The shoulderless, sleeveless dress was a bit tight around the chest, but luckily she was in a perfect position for compressing herself into it. Without pockets she was forced for the first time to take a handbag with her, a light but fashionable piece that nonetheless felt rather hefty in her weightless hands compared to when she had bought it, another thing to get used to. She was on her way to a bar, eager to find herself a man and put the sex in sex doll, no longer feeling shame from the idea or even her cheap pun, feeling like her self-confidence was unbeatable on her post-transformative high. She was intrigued by the expressions of those who saw her, a mixture of surprise, curiosity, disgust, and arousal. Dolls were a rising subculture but were still a relatively rare sight, and Kate had always drawn eyes wherever she went. 

She received a few catcalls as she approached the bar, mostly involving calling her a sex doll or an open fetishist, but she paid them no mind, having known that this was the reaction she’d get. If anything, it amused her that it was the doll part that they were focused on, having possessed a male body just an hour earlier, and now there was no way to tell! Plus, if her body was getting this reaction, she just knew that she was sexy.

She arrived at bar she had been to a couple of times with Kate, one of the rare establishments friendly to dolls and other transformed folks. But, as the male clientele knew when they saw Reyna and her curvy sexpot body walk in, dolls in particular were generally supposed to bring a friend so that the bar could actually make a profit. If they came alone then that meant they were looking for a date, and Reyna saw a wave of reactions across the men and a few women. Some turned their heads, totally uninterested.

“Too bad, sugartits. I’d have fucked you if you weren’t made out of plastic.” One mocked her, slapping her on the ass, which sunk in then bounced off in the space of a second. Another took the opportunity to reach in and rub around her belly, Reyna backing off cautiously as he sniggered at his unsuccessful attempt to unseal her valve. Rule number one of being a doll, Kate and many guides had stressed, was only exposing one’s valve around trusted friends and family members, although those who liked to live life dangerously tended to wear belly-baring clothes, daring others to try. Her dress was enough to keep her safe for now, but she was now a little more eager to find somebody more accepting.

Fortunately, it didn’t take long. It was easy to tell who was attracted to her, and she soon hit it up with a handsome young man around her age, introducing herself and buying himself a drink, getting an approving look from the bartender. Loosened up, it wasn’t long before he was openly telling her she was sexy and how hard it was to find a babe like her, and Reyna decided that this was enough foreplay. She was horny and both of them knew what they wanted, and so it wasn’t long before they had paid the bill and headed back to her place, and he’d barely had time to get his shoes off before her dress and panties hit the floor, revealing she’d been going with no bra at all. She laid back with spread legs, only for her slightly tipsy date to cough and take her hand to pull her back up, his pants around her legs.

“You’d better go on top.” He advised, Reyna glad that her cheeks couldn’t flush red with embarrassment. “I don’t want to, uh, you know, flatten you.”

That wouldn’t really be so bad, Reyna almost pouted, but climbed onto his chest instead, feeling his respectably sized cock rub between her thighs. The two locked lips, an odd feeling as his lips met plastic that felt no different from the rest of her, which only made him harder. He groped her breasts, squeezing them and squishing them between his fingers, the air inside resisting as it was less like squeezing a balloon and more like squeezing a beach ball, at least when she was filled tight with air. She awkwardly lined herself up with his cock and slowly slid down onto it, letting out a guttural moan from her first experience with female pleasure, feeling totally different to how her own penis had been, even more intense just from penetration. He began to thrust as best he could as she clumsily but enthusiastically pumped herself up and down, moaning and gasping with each motion  as she got faster and faster.

It was almost perfect, save for one thing that even her pleasure-drunk mind remembered. One last piece of the fantasy, to complete her transformation into a sex doll, the final separation between fucking a human and fucking a slutty sex doll like her.

“Take it out!” She moaned, pointing at her valve, the man hesitating.

“Are you sure? You know what that means, right?” He asked with a grunt, unwilling to cross any boundaries without her firm permission. To remove her seal, to deflate her took a lot of trust, as it would leave her totally at his mercy. It was a lot for a first date or at worst a one night stand, Reyna having been lucky to pick a gentleman.

“Just do it!” She gasped, and so he did, ultimately just as eager as her to experience it. She began to feel oxygen flow out of her navel, her belly softening slightly as her form began to slowly but surely unravel. Her toes and fingers began to go floppy, the tips of her body the first to go, her hands drooping at the wrist as the air left them, as did the power to manipulate them. Although the plastic was her body, the air seemed to contain the power to move it, and that power only left her faster as he continued to fuck her, the two turning over and putting her back to the bed as he tried to reach the limits of his stamina. Her legs flattened and she found herself unable to move her arms at all, going from tubes to merely piles of plastic in the rough shape of them, collapsing into a pile and flopping with each thrust that bounced her incredibly light body up and down. Her head ran out of air next, her hair drooping and her head falling backwards until she was staring at the ceiling, lacking the strength to hold herself up. Her nose fell inwards and her vision wobbled and shook as her head was totally flattened, the majority of her body like an empty balloon as even her huge breasts sank and turned concave.

Finally, with only a little air left in her body, he finally came, and her along with it. Even without control over her body she could still let out a deep moan, deeply, utterly satisfied. Exhausted and overwhelmed, Reyna laid back, or was rather laid back in the position she was left in,  her legs spread and her arms raised above her head, her partner lying back and eventually falling asleep next to her as she basked in the afterglow. The fact that in her deflated state she couldn’t even put herself in a more relaxed position, instead stuck looking like she was ready to be fucked, cum dripping from her plastic pussy, deeply satisfied her. She had some time to think after that, finally coming down and reflecting on her experience. It had been an ideal night, everything going just right, and now, flattened and crumpled in places, Reyna was convinced that she had made the right decision by becoming a doll, and that it had lived up to everything she’d hoped it would be. She had decided to treat it as a test run, ready to revert herself back to a normal if female human if things didn’t live up to her expectations, but now she was certain that the new doll her was here to stay. With enough control over her face remaining to emote, she eventually drifted off with a smile on her face.

The next morning, Reyna was awoken by her lover gently shaking her. 

“Hey, uh, Reyna, right? Are you awake? You can still talk like this, right?” He asked, breathing a sigh of relief as Reyna yawned and mumbled a good morning to him.

“Shit, I don’t have a pump or anything. I knew I was forgetting something when I agreed to this.” He realised, shifting awkwardly. “Uh, am I supposed to like, blow into you? I don’t think that’d actually help though… sorry, this is my first time…”

“Me too. Hopefully not the last.” She laughed. She hadn’t been certain before her date, but now she certainly was: this transformation had been the right decision, and there was no way she was going back. Still, she had let her fantasy get ahead of reality here, and now she couldn’t move, just like she had wanted. And to be honest, she really didn’t mind, but her partner, or perhaps boyfriend now, seemed to be panicking. He was kinda cute like this, and she was looking forward to getting to know him better.

“I’ve got a pump at my place, you can just take me back and we’ll do it there. I think I left my keys in…” Reyna trailed off, having just barely enough strength in her lips for them to curl into a huge smile. “Hang on, I just had the best idea…”

–

“Okay, I found it.” Her boyfriend called, digging through her handbag and pulling out a small box that was mostly plastic save for a cardboard label reading Blow-up Reyna, clearly custom-printed. “You really want me to put you in this thing? Won’t it be, you know, uncomfortable?”

“It’ll be sexy as hell, that’s what it’ll be.. You can keep me in there until you buy a pump, then unbox me!” Reyna said, dripping with anticipation. She had been carefully laid out flat on the bed, her arms spread wide. Her boyfriend shrugged, Reyna able to see him go hard through his underwear at the idea. He began to carefully fold her, first with her arms, then her legs, then finally her torso, Reyna enjoying the sensation of her flattened, deflated body being contorted into a neat rectangle, completed by folding her head backwards then placing her upright. Then finally he slid her into the box, Reyna almost shuddering with delight as he closed it, then propped her upright on his table. Unable to even wriggle, she was nothing more than an object to be used and then put away as he pleased, and it was all she could do to contain her expression while he was around.

“You good?” He asked, Reyna biting her lip.

“I’m great!” She nearly moaned out, delighted with her situation.

“I might be an hour or two before I’m back, do you want me to do anything else?” He asked politely, Reyna instinctively trying to shake her head, then remembering that even that wasn’t possible.

“Take as long as you want.” She said, content to stay there in her box until he was ready…
