The Rubberdoll Knight (Sexdoll TF)

A young man hurried to the door, having seen the mail arrive through a window. He found that he’d been right - there was a box at the door, which he picked up and brought inside. “Hey! Package here, did you order anything?” he called into the flat. There was no response.

The man lived in a reasonably nice flat split with a young woman that he only saw in the darkest hours of the night poking into the kitchen to get a midnight snack. It had been an unusual rent agreement, with strong stipulations about respecting her privacy and not prying into her affairs to a point of comedy. He’d been worried about it at first, but she paid her share each month, and left him the run of the house during the day, so he couldn’t complain.

Anyway, if this wasn’t her package, then that meant it was his. Finally, the figurine had arrived!

The young man had been looking forward to this for some time; it had been a total pain to find anywhere with this one in stock, since whenever they went up for sale they sold out in an instant. It had taken a fairly long delivery time for the international shipping, but he was patient, and his patience had finally been rewarded. He gently put the parcel down on the kitchen table and set about opening it, carefully slicing the wrapping

He let out a gasp of excitement, seeing a pale blonde ponytail print peek out from the layers of brown paper. With shaking hands, he tore more of the wrapping away, revealing the smiling face of his newest obsession: Jean Gunnhildr, the graceful and stoic character from Genshin Impact, a game he’s lost many an hour of free time to in the recent months. Clearly, he wasn’t the only Jean fan in the world: getting this figure required many sleepless nights trying to snipe bids on Japanese auctions. He’s lost time and time again and now it looked like his persistence finally paid off.

Strangely, the front of the box didn’t look quite the same as he remembered it from the pictures online. There were colourful kanji characters covering every inch of free space around Jean’s face; a design so tacky and chaotic it’d be hard to believe this was official merch. He gulped, trying not to consider the possibility of being sold an off-brand bootleg. Seeing no reason to hesitate anymore, he cut the tape covering the top of the box and opened it.

As he prepared to look inside, the package began to glow.

“Huh? What’s… whoa!”

The light engulfed him completely, pink flooding his vision. He stumbled backwards, barely keeping his footing.

When the light faded, he tried to blink the stars from his eyes. What the hell had that been? Some porch pirate countermeasure or something? He tried to walk back towards the table and nearly tripped over again; he was having a hard time keeping his balance. Maybe the light had disoriented him more than he thought.

His trip bumped the table enough to knock the box off of it. Cursing under his breath, he rushed to pick the thing up off the floor. The thought of the fragile figurine breaking worried him far more than the weird, pins-and-needles feeling in his feet. He plopped himself down on a chair next to the table and took a closer look at the parcel, only to find… nothing inside.

It was empty!? “What the hell? Did the delivery guy rip me off!?” he groaned. His heart racing, he tore all of the wrapping away, throwing it on the floor in nervous haste. Whatever was happening here, a stolen item or a bootleg, he probably got the short end of the stick.

He grabbed the box by its sides to get a better look at Jean on the front and froze in disbelief. The illustration showed Jean sitting in her office smiling, yes… smiling while spreading her legs under the table and touching herself through her tights, a wet spot on her crotch. The man couldn’t believe his eyes. He turned the box around only for his suspicions to be confirmed: there was a photograph on the back, a photograph of a shiny inflatable sex doll in an image of Jean. Cheap-looking blow-up doll, complete with two onahole inserts, as gleefully advertised by the side inserts.

He set his new box aside, thoroughly confused. Had he purchased a sex doll by mistake, too hasty at seeing some Jean merch not sold out? Or was this not his order? And why the heck was it empty? The strange feeling had climbed his legs now - maybe he’d bumped something when he stumbled? It didn’t hurt, but that must have been it.

He sighed. The only thing left to do now was contact customer support on the auction website. Rising from his seat, he found himself tumbling to the hard kitchen floor, his leg twisting unexpectedly. Panic began to creep into him - was he having a stroke or something? He didn’t feel bad besides his legs, but he had no idea what a stroke felt like?

Maybe something was up with his feet? The young man worked to pull off his shoes, which seemed much more difficult than it should have been. With a soft pop noise, they came off, and he hurriedly pulled his socks off with them.

He stared uncomprehendingly at the sight. His feet… weren’t, anymore. Really, the stubs he saw couldn’t really be called feet, moreso just his legs ending in a point. In his shock, he checked his shoes to see if something had been left behind, but no; that was it. He pulled up the pant legs and saw that the effect extended upwards, his pale skin replaced with pure white with a gold trim.

What the hell were those? Grunting, he bent forward to feel at the former-feet, and found them giving way under a squeeze. They had a rubbery, synthetic texture, completely unlike anything natural. And as he felt around, he found… was that a seam? It was, as if his legs had been glued together from sheets of whatever material they had become. And the way it continued up his legs…

He hurriedly pulled off his pants, to find to his horror what he’d expected. The shiny material was progressing up his skin, already approaching his knee. He felt along the creases and seam, felt at the point where rubber transitioned to flesh. What the hell was this? This wasn’t something that could realistically happen, but there he was watching his legs turn to cheap rubber.

He couldn’t just… sit there, waiting to transform into whatever it was he was becoming. The white and gold plastic wasn’t waiting for him, continuing up his skin as he grabbed at the edge of the kitchen table, trying to retrieve his phone. His feeble legs wouldn’t support him anymore, and he had to use all of his upper body strength to pull himself up and grab the device. He slumped back, and his butt landed right on top of his new rubbery stumps. He squeaked as a pleasurable sensation ran across his body as the inflatable limbs gave in under the weight. He shivered. Shifting back into a sitting position, he heard his new legs and thighs hiss as air rushed back in, now making them even bigger and plumper than before. This was too bizarre to believe, he realised, putting the phone aside. No emergency dispatcher would help him.

For a few moments, he was frozen in a panic. He could feel the change continuing - he was getting stiffer, it was getting harder and harder to move. He could still control the transformed parts, still sort of move them, but he felt they were trying to pull into a specific posture and it was harder by the minute to resist that. He cried out as the change reached his groin - something was happening there, and he hurriedly pulled down his underwear to see.

His manhood hadn’t been anything special, but it was his. And he watched as the white rubber ran up his crotch and began to coat it, before pulling inwards. He gasped, not from the surprise, but the pleasure. It felt good, the way it pulled inwards, his already rubber-coated penis shrinking and slowly vanishing inside of him. It grew erect from the feeling, but even that only extended its existence by a few seconds. There was a plastic pop sound, as it finally vanished, leaving a circular, off-white rubber hole where it should have been. He moaned in despair.

That wasn’t all, either - he’d been focused on his manhood but his rear end hadn’t been spared. It swelled outwards, blowing up like a balloon until it was a thick cushion to match his thighs. He felt his body lifting up as his latex buttocks inflated. Shifting to one side, he reached his arm around to the back, finding another hole there, a hard plastic ring around it.

He had to see what was going on to even begin to guess what was happening. The box, that might have something to do with it! And there was a mirror in the other room…

Grabbing the box, he tried to steady himself as he slowly stood up on his fours. The legs seemed inflated tight enough now to support the rest of his quickly changing body. He moved his arm. Then his leg, Then another arm. Very, very slowly he crawled across the house , trying very hard not to focus on how nice it felt whenever his rubber legs squished and distended against the floor. Whatever was happening to him, ‘good’ was not a description he wanted to find himself using.

The living room had a wall mirror, so he saw his own sorry state as soon as he approached the doorway. His shiny, rubbery ass wobbled slightly with each step he took. Beads of sweat glistened on his face distorted in a grimace of desperation and humiliation. He crawled closer before collapsing flat on the floor in exhaustion, plastic butt sticking up, supported by stiff legs. Glancing up at the mirror, he saw the change had progressed above his hips now. A streak of blue appeared at his lower back, lined with red gold. On his left thigh, a print of an intricate golden trinket with a teal gem etched its way into being. He had seen this thing many times before. He looked away, blushing, not willing to believe what was being made increasingly obvious to him.

With a grunt and a creak, he rolled over to sit on his butt properly, his legs spreading to the sides in an ‘M’. He could never do splits before, but for his new inanimate form the pose came with ease - and a tinge of pleasure, as the plastic ring between his buttocks touched the floor. He reached under his shirt, feeling the smooth, slick surface that replaced his skin. The buttons took some work, his fingers stiff both from the nerves and the tingling sensation. His white shirt dropped to the floor and he saw his change in full glory. The latex had begun to change his abdomen, a printed-on belt etching into existence. A thick vertical double seam ran from his crotch to his waist where it meant another, horizontal one.

The young man reached for the box, hands shaking. He forced himself to look at the photo on the back. He glanced up at the mirror. Then the photograph. Then the mirror again. Then the photograph, once more. He slowly traced his finger across the seam on his waist. It bumped into something hard, protruding from his side. The man groaned. It all matched. The golden trim at his former feet, the golden crests, the diamond pattern on his tights, the belt and the beginnings of a black and red corset painted on his torso, the seams - everything! He was turning into a blow-up Jean sex doll! He took one last look at the box before throwing it away in frustration. “No, it can’t be, I don’t want to be a doll, I- this isn’t real!” he shouted, the image of lustful printed blue eyes self half-closed in overwhelming pleasure haunting his mind. He studiously avoided paying attention to the holes on his crotch and ass, but after seeing that photo it was getting harder and harder to do.

Looking back at the mirror, he tried to steady himself. Surely there was a way to stop this? He could not turn into a sex doll, that just wasn’t a thing that happened in real life. Not even a doll of a beautiful, alluring character like Jean! He unfortunately found his gaze always drifting back to his crotch. Was it… really gone? Replaced with a hole meant only to take dicks? Despite himself, he let his fingers slowly approach, brushing against it-

His entire body seized up at the sensation, back arching as he let out a shocked shout. That had felt good. His fingers hadn’t even entered his hole, and it was like he’d been struck by a lightning bolt of pleasure.

The young man recovered after a few moments, panting heavily. That… he shouldn’t play with that feeling, he knew. But a small part of his mind argued - what if that’s the key to turning back? Finding where that thing between his legs went and pulling it back? It was completely irrational, purely an excuse to explore those feelings further, but after that thunderbolt he needed only the thinnest strands of logic to justify it to himself.

He threw caution to the wind - if he hesitated he’d be stuck just brushing that little hole all day. There was nothing for it but to plunge right in. The young man took a deep breath and shoved one finger right inside.

He quickly put his palm to his mouth to stifle a scream, the shout of pleasure loud even muffled like that. It felt so, so good, he couldn’t stand it. He found himself dropping in another finger and then another, spreading the new hole as wide as he could. He desperately fingered himself, the tension building and building. He closed his eyes and bit his lip, oblivious to the change that sped up with each thrust of his fingers.

The white rubber continued unabated, but soon, other colours would join in. Black stripes with golden ‘buttons’ for the sides, and white and gold for the center, it crawled up his body rapidly. It was reasonably well drawn, but that’s all it was - drawn, giving the illusion of depth where all it was was a few different colors printed on plastic, a nice gold symbol of Jean’s home nation on the waist. That waist narrowed heavily as the young man's transformation progressed, to a point even narrower than that of the actual character depicted.

And all the while, he continued to touch himself, lose himself in pleasure. The unfortunate thing was that for all the building and building ecstasy, he had no release; he’d hit the point where he would have orgasmed well before, but a rubber hole couldn’t exactly do such a thing. But that hardly mattered to him, as his perspective warped - was it so bad if he could feel like this? Couldn’t he take a day off work? His friends taught him the importance of resting every once in a while - was this really forbidden? He hardly noticed as the change reached his chest, white rubber transitioning to pale skin tone. At least, he didn’t notice until with a harsh squelching noise, his chest began to expand, breasts forming and ballooning outwards, thin seams encircling them

For a moment, the shock of it pushed the man out of his aroused reverie, but as he reached up to investigate the reality he found that his new bosom was no less sensitive than his lower hole. A new yelp of pleasure tore its way from his throat as he started to grab and grope, playing with a new source of bliss without regard for the consequences.

She needed more, she needed to be filled. Her fingers weren’t enough, not even close to enough! Unwilling to let go of any part for fear of reducing the pleasure, she writhed on the floor, searching for something, anything, to fill her nether regions. The doll in the making desperately clawed at herself, squishing and twisting her inflated body in unnatural ways, seeking release. But all she got was just harsh creaking of latex rubbing against flesh. Her gaze drifted past the mirror again, and the shock was enough to snap the young man out of it - what was he doing? He was turning into a sex toy and his first concern was to touch himself!? In horror, he realized he was running out of time - the rubber had claimed his torso completely, and was now beginning to creep down his increasingly slim shoulders.

He had to tell someone, find someone. If all they found was a Jean sex doll, with a box for it, nobody would ever realize it was him! He had to let his flatmate see him, as embarrassing as it was.

The crawl towards her abode at the back end of the flat was even more humiliating and pleasurable than the trip to the living room. At some point in his arousal-fueled grope session, his legs had further stiffened until they could hardly move out of their pose of wide-spread invitation. He dragged himself along the floor, hole scraping against it and driving him mad with pleasure. With every inch of progress his inflatable breasts would grow bigger and bigger, first just getting in the way, and then contributing to the mind-melting wave of ecstasy as the tiny plastic nubs on them began to flick against the floor. At this rate he wouldn’t have much time left even if the girl opened the door. Only his forearms remained human now, the rest of it a white sleeve and the beginning of a long black glove.

He started knocking like a madman. “Hey! Hey, open up! Emergency! It’s an emergency!” he called, hitting the door so hard he felt like he’d hurt his knuckles, but as he did that banging transitioned into useless thumps - his hands had finished their change, stubby black mitts that couldn’t bend, let alone have any force put into them. He clenched his teeth, trying not to lose himself to pleasure that was invading his mind with each hit on the door.

Thankfully, his flatmate seemed to have heard. “Jesus Christ, I’m up, I’m up!” she called, coming to the door. The man heard the sound of at least three distinct locks being unchained before it swung open.

She wasn’t anything special to look at, mostly keeping to baggy clothes and old, hole-ridden jeans. She brushed some scruffy black hair out of her eyes, prominent dark bags under them, and squinted downwards. Their gazes met.

“I-I don’t know what’s happening- hurry up and d-do something!” he stammered, feeling the plastic creeping up his neck.

“...Where’s the box?” the young woman asked after a brief pause. She didn’t seem shocked at the sight, to his surprise. A look of mild curiosity and annoyance was all he was getting.

“E-Excuse me?” he asked, confused.

“The box!” she snapped. “The one that did this to you!”

“Living room!” he responded, trying to point back towards the corridor, his torso creasing and squeaking for a second before it snapped back into position.

She stepped over him, making her way into the living room. He heard her grab the cardboard before moving to the kitchen. Letting out a moan, he saw his hands rise higher, stuck in front of him in a “Hug me!” position, just like in the picture on the box. He felt his entire being stiffening up.

“What are you doing? Please, come here and help!” he shouted, unable to turn his head anymore. He heard a rustle of wrapping paper, quick steps, and then a hand wrapped around his waist. He squealed as he was lifted to face the girl.

“Patience, patience. You really should be trying to enjoy this instead of freaking out, you know?” she giggled as they entered the dark of her room. The door slammed behind them.

It was the first time the young man had seen that place. It was a complete mess, an image out of an anime where the main character never goes out: CDs and books strewn everywhere, wall scrolls with anime girls in lewd situations, leftover instant ramen on the table...But he also couldn’t help but notice that in between all of that were strange wooden dolls, bits and pieces of fabrics, a box full of leaves and roots, and… was that shelf full of potions, glowing softly? The woman unceremoniously dumped him on the bed. “You really shouldn’t go through other people’s stuff” she said, flicking the man on the forehead “That package was mine. Sent by a wizard friend - with an enchantment on it, it seems. Not sure whether this effect was meant to protect it from unintended people opening it, or if he meant to prank me, but whatever - you’re turning into a sex doll now, as I’m sure you noticed.”

“What!? An enchantment? What are you talking about?” the young man asked. “That’s not- ah!”

The girl suddenly grabbed him by the arm, squeezing it tightly.. “Can you feel that? What about this?” she rubbed her dainty hand on his painted-on corset. Her painted black fingernails dug into the pliable rubber.

“Stop ‘hat and ‘elp-” it was getting hard to speak now, as his mouth started to be taken. His bottom lip had thickened dramatically, forming the lower half of a bright red circle shape.

“I need to understand what’s happening before I can help. Can you feel this?” she smiled, poking right onto the breast.

“Ooo! ‘Es o can!” the young man managed, but even that was much more than he could say clearly. “‘Wease, ‘elp- ooo!”

With a pop, the young man’s mouth finished turning into an ‘O’, forming another hole never meant for speech, but only for receiving. The witch rolled her eyes. “You shouldn’t be so demanding.” she said simply, before climbing on the bed and beginning to poke and prod more… and grab… and twist…

“Whas oo dooin!?” The young man protested, trying not to moan with pleasure as she pinched his too-pointy nipple.

The girl grinned. “With the state you’re in now, I’m guessing you took this sweet little body for a ride earlier, huh? I know what sort of spell got put on you now, so I bet there was something that you couldn’t quite do yourself...” she said, giggling, She took a moment to pull out her phone. “Smile for the camera!” - she wrapped her hand around the doll’s shoulder, pulling her in closer for a selfie. He moaned as he looked at the screen: the girl, with her lewd, mocking grin, and him with his fuck-hole mouth and the change continuing - he didn’t have a nose anymore, a mere painted-on shadow above his mouth. “I’m just gonna help you out a bit~”

“Whas oou ean!?” he squeaked, but she refused to explain further as she pressed against him, the sudden squeezes and gropes starting to drive him nuts. She grabbed his breasts, squished his ass, laughing all the while. But it wasn’t until she brushed herself against his crotch that he suddenly understood - as a sex doll, he couldn’t orgasm without the help of someone else. And she’d just pushed him right over the edge. “OOOOOH!” he screamed as he came, another snap of the camera as the witch took another pic.

“Shoop!” The young man demanded, but it wasn’t very convincing - the words were practically drenched in pleasure, and the woman meant to have her fun. She continued to play with him, finding and mercilessly attacking all the most sensitive bots on his body. A light squeeze here, a lick there... His mind drifted with pleasure, vision growing hazy. The girl’s soft honey-brown hair brushing against his cheek, those luscious, stocking-adorned legs locking themselves with his... The pleasure built higher and higher each time, before inevitably leading to an orgasm, and then another one. With each climax, the change progressed further. With each climax, he heard a ‘click” of the camera..

The man’s curly black hair melded into a mass of thick, hardy rubber as it began to take a new shape, flowing down slowly It was clearly glued onto the head, rather than naturally a part of the doll; pretty much the only part of it that wasn’t painted on. A valve popped out on the side, opening a new inflation chamber. The dolls’ tormentor wasted no time and flicked it open. It was the most bizarre sensation, to feel your own hair in its entirety, and not only feel, but to come from it being stroked and blown into.

“Fshhh! Fshhhh!”

The ‘hair’ started to brighten in shade, becoming lighter and lighter with the girl’s each breath as it popped out into a cute, bouncy ponytail. A pair of thick inflatable bangs stretched down to brush the doll’s shoulders. The girl playfully pulled on them, pulling her toy’s head down, filling its field of vision with its huge, tight, air-filled breasts. She let go, and the head snapped back, bobbing back and forth. The witch laughed, adjusting her purple hat.

“Look, aren’t you pretty?” her feminine, sultry voice was as smooth as honey. Comforting. Gentle. The doll paid next to no attention to the images on the screen, a gallery of snapshots telling a story of her hair changing into a cheap facsimile of Jean’s hairstyle.

“Oooh, pwease…” the doll moaned, but it was no longer sure what it was saying please for. It felt like it should have been ‘please stop’, but that didn’t seem right. “Please continue” seemed more correct, and the doll’s owner obliged - she stuck one finger, then another, into the doll’s hole and started exploring. “Oooner…”

The doll’s head swam with sensation as she came and came. Jean felt so good… so good. It was hard to remember what she’d been so worried about as the walls shifted, moving away to make the room a much more open space. Moonlight gently illuminated a heavy wooden table on the far side. The potions she noticed earlier twinkled in the dark near the bookshelves. The witch finally turned her around for a face-to face. Jean saw green eyes looking at her gently.

“Let’s have a bit of fun” the woman said, grinning lewdly as she fingered Jean where she sat.

Even Jean’s earlier private explorations paled in comparison to the bliss she felt at that. “E oodn- oot ere- Ooo!” she cried out, finding it hard to move her mouth with how stiff from pleasure she was. Her office was hardly the place to do this… but she found she couldn’t care. The pleasure of another being, of Lisa, enjoying her and using her body, was far too great. She hadn’t realized she’d be so submissive in intimacy, but that was just one of many things Lisa was teaching her. She came, again and again, as her pleasure peaked and crashed with each thrust of her girlfriend’s fingers. The change rapidly approached it’s conclusion unnoticed and uncared for by Jean. She just saw Lisa taking out a weird device and then showing her some portrait of herself, before giving her a kiss.

The doll’s new owner had taken one final selfie as its eyes became the painted-on pale blue of Jean, half-closed in intense arousal. As the doll finally went silent, the woman took a moment to give it a deep kiss on the mouth, exploring the folds of latex on the inside of the plastic tube insert, knowing too well how it must feel for the former guy. She withdrew with a playful smile. “Don’t worry… whatever your name was, it’s probably Jean by now. I don’t plan to keep you like this forever. But I ordered a fuck doll, and I’m going to use it. Maybe that’ll teach you not to look at other people’s mail, hm?”

For all Jean cared for, Lisa had said some sweet nothings, and then left her on the couch. Jean was put in a perfect place to watch as her girlfriend stripped off her skirt, followed swiftly by her panties. If she were capable of independent motion - she’d orgasmed far too hard to move - she’d have been unable to contain her excitement! Lisa was going to do it with her right there… it was so wrong, to do it in a place they could be caught, but just then, in that moment, Lisa may as well have been the leader of the Knights of Favonius and not her. Lisa returned to her submissive partner and positioned herself. She put her legs over her Jean’s, and gripped those legs tightly as her dripping womanhood was poised against Jean’s. Then, she pulled.

The doll’s light weight meant she had to be a bit more forceful, but it wasn’t the first time for her, and the doll’s fake plastic pussy was surprisingly pleasant to touch. She rubbed herself against Jean with enthusiasm, milking all the pleasure she could out of that soft latex body. To Jean, Lisa was scissoring her, driving her to orgasm after orgasm as they rubbed their pussies together and mixed their wetness. Jean was a moaning mess from the word go, but as the pleasure grew even Lisa began to pant; she pulled more tightly, smashing their nethers together once more as she came. Jean came the hardest yet, her mind going blank from the sheer overload of pleasure - the only thought in her head was how impossibly happy she was.

They lay there for a moment, enjoying the silence.

“You know” the witch rose up, facing her newest toy “I might just let you keep memories of this when I turn you back”. She sat on the edge of the bed, hugging the inflatable Jean from the side.

“From now on you’re paying for the entire flat, though”.
