"Nekomimi" also known as 'Nekos' or 'Catgirls'.
Pauls grin became infected with childish glee as he looked upon the object that would fulfill his wettest fantasies and dreams in just one go. Being a fan of both Anime and Hentai for more or less his entire life has meant he'd always been a little odd in the head, though he didn't let anyones opinions bring him away from his fantasies. He was particularly fond of Hentai's though, especially those one-off hentais where the MC gets to fuck someone silly because of some bizarre reason, particularly when the girl has those huge badonkas to squeeze. Though he became especially interested in catgirls when he found a one-off about a security guard catching a catgirl burglar with huge tits and proceeding to fuck her brains out in an alley when she says he can use her body however he wished so long as she didn't go to jail, so thats what he did, when they were done he dumped her spasming, cum-flated and cream-covered, bod into a nearby dumpster, then we find out the neko proceeded to show-up, then get caught by the protag multiple times, all ending the same way, then we find they get married, and continue their little game.
That one-off hentai inspired Paul to find other neko-related hentais and was how he found one hentai in particular, this one a little series. In this, the protagonist is quickly established as a cat-person kind of loner who was just going home one day after work, arriving home everything is normal and he greets his cat Nyarlet (a play on scarlet because of her exotic fur-colour) and goes to play a little in his room. But before he can really start his game immediately crashes, inconvenienced he goes through his living room to check on his router, walking past a cat-aired redhead on his sofa obliviously before doing a double-take on the other side of the room. There in his sofa lay a voluptous redhead catgirl clad in a fancy skintight suit that did nothing to hide her naughty-bits, eventually noticing his stare the radhead neko seems briefly confused before asking 'Is it time master?', shaken from their stupor the MC asks who they are and why she called him 'master'.
Which prompts the neko to stand up (showing off her suit-clad curves) and gladly declare that he's been 'chosen' for the 'Nekotama's' 'Expansion program' and that she's Nyarlet. The protag is absolutely stunned by this and asks what the expansion program is, Nyarlet happily obliges and tells him (and us) that the program was essentially a rather complicated breeding program for the expansion of the 'Nekotama' race, all while slowly approaching our protag. Then they begin to fuck with Nyarlet taking the lead after a quick application of a 'clothes remover' and 'penis enlargement' raygun, this of course eventually turns into the protag taking the lead and banging Nyarlet into submission. When they finish (and Nyarlet is coated and bloated in semen) she reveals that he'll also have to fuck some of the other 'Nekotama' and contribute atleast 450 new babies to their race as per the programs requirement, the protag asks what happens when that is done and Nyarlet giddily states that'll be a 'surprise'.
The next episodes then go over some slight worldbuilding together with good-old hentai shenanigans where the protag finds other disguised 'Nekotama's' and bloat their wombs and creams their tits before the final episode where the MC is pulled into the Nekotamas spaceship where he gives more or less every Nekotama a second filling (by this point he'd also given Nyarlet multiple fillings). Here we discover that the Nekotama are a hyperfertile race that offload their embryos into machines instead of bearing them normally, and that they have a custom of pretending to be a species pets to determine suitable targets for their 'expansion programs', after a stray question from the MC about male cats the 'Nekotama' confirm that there are indeed male 'Nekotama' aboard their ship. having succeeded in supplying the 'Nekotama' 450 new members the protag then asks Nyarlet (who demonstrated how to offload newly fertilized eggs just prior) what happens after, at which point Nyarlet hastily applies some kind of pink lipstick to her lips before declaring that the protag will recieve the task of supplying 49 more babies before locking him in a kiss, afterwhich he is embraced by every other Nekotama introduced in the series. And when they finally pull away from the Protag we find him having turned into another female Nekotama with huge tits and the others begin to welcome them into their society before we see a male Nekotama reveal themselves (already naked) and their huge cock. As the episode ends we see the MC enjoy themself as the hung catboy cumflates their belly to pregnant proportions and a final declaration of 500 new members.
In the end Paul became overtaken with a bout of extreme 𝘸𝘢𝘯𝘵 to become a big titted catgirl right then and there, which made him do some searching on the internet that then lead him to find out about the Hentai Potion that could make you a full on hentai-worthy whore. The discovery only fueled his bout of desire into a full-on obsession that he pursued feverishly when he wasn't masturbating to more catgirl hentai or getting his computer fixed due to some annoying dead-end virus. And finally, finally finally finally finally. Here, in his hand, stood the fruits of his months long labour, and he was determined to take his reward with open arms and zero hesitation.
With his mind made up months ago, and reminiscing at an end Paul popped the cork on the potion and chugged the holy concoction before slamming the empty flask unto the emptiest patch of his desk, oblivious to the couple prized figurines falling off it. Already a dizzying haze tickled his body, before a burp let him know the concoction dissolved in his stomach at the same time a painful gurgling erupted from said portion of his body, making him take a couple uncertain steps back while grasping his midsection in discomfort. Then his agonied stomach became the lesser of his worries when his dick wanted in on the action, becoming painfully rock-hard it swelled, pulling dizzying amounts of blood into itself as it begged for release, like a pipe under extreme pressure it seemed bloated as his balls expanded painfully aswell, bringing Paul to his knees as he began to furiously stroke his rod in an effort to ease the pain and sheer discomfort.
Yet simultainious to the discomfort and agony of his stomach and overcharged stick, changes began to ripple across Pauls body, heedless of his pain and discomfort. The first to change was the elimination of Pauls bodily hair, his skin turning from rugged and hairy to smooth and unblemished in ripples across his form. In its wake Pauls face took the opportunity to gain a more feminine definition, while his facial structure remained untouched (for now) his lips became more full and plump, and his eyelashes becoming longer and more defined together with his eyes turning an expressive and shiny sapphire blue as his hair turned a scarlet red. With the male skin reduced to a females silky smooth hide, Pauls feet were the first to physically change, fat relocating from his measly legs into his measly thighs, giving them a feminine shape as his feet turn daint and soft, hiding whatever muscles he's built beneath silky flesh and hide. Up above much the same occurs to Pauls hands, his dizzy, vertigo-plagued mind wracked with the dicomfort of his sexual organs unable to correctly register the much diminished frame of his hands as soft, daint fingers with freshly-manicured nails as the shape of his arms thin into the soft, demure forms of a womans arms with the leftover mass making the start of his motherly mammaries as his masculine pecs soften into near unnoticable bumps tipped by yet untouched nipples.
With the relocation of the masculine mass of his limbs, Pauls torso began slimming, the mass of his receding belly falling down into his unremarkable rump, pushing it into the plump shape more at-place to the average woman than the end-product of Pauls venture. His upper torso giving mass to his demure lumps as his shoulders thinned and his stature shrunk before his face finally cracked into the youthful epitome of a mature yet energetic and playful woman, while his scarlet hair billowed down and over her plump rear, becoming soft, silky and luscious. Pauls waist seemed to just get the memo and chose the moment to cave in, flushing mass into his still-masculine hips and cracking them into proper womanly proportions but not still not the correct proportions. This final step into the conversion of Pauls form from pathetic and boyish to demure, young and feminine now faced its final step, namely Pauls masculine genital currently being stroked and rubbed by thin and daint hands with silky smooth skin, had it not been under the unatural mercy of pauls dream concoction it would have surely released its load, especially under the continued service of such demure feminine touch. Yet finally, with its use close to expiring, the unseemly tumor on the daint and fair frame of Pauls form was permitted its removal from his (soon her) form, and to wave goodbye it unleashed upon him a final release.
And go off with a bang it did.
"𝗚𝗔𝙰𝙰Aaa~~aaaAAA-"
With an explosive push and final flush the fire-hydrant of cum was opened, with a torrent of unseen proportions a jet of hot sticky jizz shot forth and immediatley splattered Pauls desk, coating his monitor and blowing away the rest of his figurines with a mess that would take years to remove. Yet Paul at that very moment was far above worrying about such material possesions as simple as figurines, and was more preoccupied with experiencing the strongest burst of masculine pleasure he will ever have the honor to experience as his balls rapidly flushed and inverted into his female ovaries, while his masculine voice was quickly replaced with the energetic voice of a young, optimistic woman currently screaming unbidden with a voice of pure pleasure, replacing the guttural, inelegant scream of an introverted and creepy man as his body was suddenly overcome with a burst of activity.
"-AAAAAAAAAAAAAAAAAAAAAAHHHMMNNNNNNNnnnnnnnn~~..."
The geyser of cum that was Pauls last reminder of the life he was leaving began to weaken, before his shrinking stick of an appendage began spitting thick globs of cum, that too eventually stopping before the remains of Pauls masculine visage was sucked up with a wet *SLUrp* that signalled that Paul was suddenly gifted with a tight corridor for milking cocks and a spacious, stretchy womb for holding gallons of baby-batter. A change that finally declared her fully a female, and a declaration celebrated by his body as mass suddenly began to add to her femininity, turning the barely-C-cup bumps on her chest into blooming F-cups in a display of comical lewdness not too dissimilar to balloons being vigorously inflated in but a second. Down below her pair of well-cushioned buttocks also decided to get into the action, bloating into exceptionally plump proportions supermodels needed ugly surgery to reach, their soft firmness just begged to be groped and fondled by strong and burly hands while her feminine hips violently cracked outwards into wide supermodel proportions, her thighs also joining in and thickening into exceptionally juicy sticks of plumpness that hid strong muscles behind its soft and kneadable flesh.
But these admittedly gorgeous additions to Pauls body did not fully encompass the spirit of his changes, and thus these unpermissible grievances were erected in yet another moment, a moment where Pauls measly F-cup orbs continued to bloom, the orbs becoming meaty J-cup spheres that sloshed with milk and seemed to beg for someones touch, for someone to knead and milk them of its liquid. Much the same continued with the rest of her hourglass curves, Pauls waist thinning some more while her hips cracked further apart into childbearing proportions supermodels could only dream of, then her thighs and plushy butt mirrorred the increase in mass and became equally as above-reach of humans as her lewd milkmachines, her large, jiggly ass begging to be fondled as the exhausted Paul fell backwards, landing her rearward pillows onto his floor before the rest of her form landed limply, her lewd mountains splaying to the sides as she revelled in the aftermath of her explosive release. And with her body finished in its proportions, the final additions remained, a slight tingle in Pauls ears signalled a sudden poof of fur as they softly stretched and moved before settling atop her head of crimson, down below a sharp tug on her tailbone signalled the sudden explosion of a brand new limb, this one long, thin and covered in scarlet fur.
And so was it that Paul felt the end of an incredibly uncomfortable change (punctuated by his last male ejaculation) and lay sprawled in the middle of her room with a body remarkably similar to Nyarlet (his inspiriation) but lacking the red and amber suit she usually wore in the hentai. Eventually Paul regained some measure of lucidity with his mind still recovering from the sensational rollercoaster that was her change, which was why she eventually went and stretched out her limbs, stewing in the brand-new sensations generated by her brand new bod and especially the sensations of her massive badonkas and pillowy asscheeks or her pussy-juice coated thighs. The twitching lips down below elliciting bouts of shivers up her spine as she absently rubbed her fat thighs together, absently letting a small 'Nya~' escape her full lips in response to the feminine pleasure rippling through her form.
Her mind resolving the turmoil of sensation, began to feel lust as dormant desires and fantasies resurfaced, relaying pictures of lustful depravity into an awakening mind, views of catgirls banged into submission, of Nekos coated in sticky white semen, of cat-eared women having their bellys inflated by the overflowing cum of a bull-like man. To the disoriented Paul, these fantasies were not merely goals desired by the past him but the very purpose of the new Paul, her fragmented, malleable mind willingly reorganizing itself into the depraved slut he had envisioned himself as becoming the day he found out about the key to his rebirth. Slowly, surely, the redheaded catgirl with the body more at-place in a hentai rose up with a newfound dexterity, the very symbol of the ideal womans body to every horny degenerate around the world turned to look into a full-body mirror the past-Paul had seen fit to acquire.
Shown off in a mirage, Paul saw her nude form on full display, the young, cute and energetic face twisted into an expression of lustful hunger as she licked her lips at the shape she witness before her, scarlet red hair cascaded down her bod like a tasteful waterfall, reaching down to her fat & tasty ass jiggled to her movements, a long, scarlet-furred tail swayed behind her luscious rump. Up above, two pairs of scarlet-furret cat-ears twitched sporadically atop her head, standing tall at attention and picking up every nearby sound (which were currently ignored in favour of her shapely bod). Thin, dainty hands drifted purposely upwards, from caressing her hips to lovingly caressing her huge, milk-filled spheres that hung proudly atop her chest. "Nyaah~" Came the lustful voice of a young, up-and-at-em woman in response to delicious sensation, the meaty spheres bouncing to her prodding and radiating pleasure from her pokes, atop these mountains proudly stood her teats, large and ready they made ripples of ecstacy with Pauls every twist and squeeze, trailing down from her massive globes to her thin waist, caressing the not-too-thin bottom of the curve before descending to her wide, motherly hips. Before moving to her bulbous, jiggly rear, revelling in the waves of pleasure they made to her self-teasing gropes as she imagined the large and heavy hands of a man upon them.
"Nya~" She mewed once more, before eventually her hands trailed down, caressing the meaty drumsticks that was her juice-coated thighs, finding the sticky fluid and spreading them. Paul then closed her eyes as her hands began feeling adventurous, her mind swimming in the ecstatic sensations of her sensitive new form, her hands then getting trapped between her meaty thighs as her hands began rubbing and feeling steadily higher and higher. A purring had began to reverberate from behind Pauls luscious lips as she squirmed to the pleasure.
"MH!~" She squirmed as her fingers touched her naughty lips, her cunt continueing to gush lubricating fluid and soaking the delicate hands.
"Ah!~" She exclaimed as her lower lips were parted
"NYAAH!~~" She screamed as her finger dove in with a mind of their own, the mere push sending her to the edge of an orgasm.
"MYA!~ AH!~ NYA!~" She mewled in pleasure as her hands probed 𝘥𝘦𝘦𝘱𝘦𝘳 into her lewd hole before jerking out, then 𝘱𝘭𝘶𝘯𝘨𝘪𝘯𝘨 back 𝘪𝘯, shaking her entire body as her legs trembled, rivers of lubricating juices rushed forth from the assaulted genital, coating her legs in her fluids. It didn't take long for her legs to eventually buckle, landing the slutty catgirl squarely unto her rump as she leaned forward, attempting to drive her hands 𝘥𝘦𝘦𝘱𝘦𝘳 into herself but only really succeeding in jostling around her giant mammaries, the slooshing of milk easily heard by the lewd cats ears and only driving her mind deeper into ecstacy as she pushed herself.
"NYAAAAAAAAAHHHNNNNN~~" Pauls scream loudly declared her first-ever female orgasm to the world as her muscles seized and pure ecstacy flooded her brain together with a deluge of information. Her gushing cunt opened up and let out a deluge of juices, coating her thighs and floor with Pauls fluids while her spherical milkmachines seemed to compress, squeezing out fountains of breastmilk and bombarding Pauls brain with pleasure and ecstacy as her twitching form jostled them more, carelessly sending sprays of milk all over her room for several long seconds before petering out, then stopping. Leaving a fluid coated catgirl splayed on the floor of his room that had passed out from the relentless bombardment of pleasure upon her mental sanctum, driving her to shut down to avoid being overwhelmed.
-----------------------------------------------------------------------------------------------------------------------------------------------
"Mh~" was the first noise Paul made upon stirring from unconsciousness, slitted eyes fluttering open and dizzyingly taking in the hentai-covered roof of his room.
"Nghn" she groaned as she swayed her torso, feeling the heavy sway of his milk-stuffed goodness atop her.
"Mmnnnngh~" She slowly rose, then stretched her 5"5' body infront of the (unstained) mirror, relishing the bouncy sensation of both mammary and ass as she looked at her mirage and smiled with her tasty lips.
"Paul." She stated.
"Is unfitting for this~" She posed with both ass and tit on full display, hefting a meaty sphere and grabbing a pillowy cheek.
"From now on," She bent over, giving the mirror perfect view of her wet cunt and tight ass while continueing to heft one breast and displaying it with a slutty grin.
"my name will be Nyarla~" She finally states as she sits back down and spreads her legs for an invisible man, a lustful smirk on her face as she gave her tits a push-up effect with one arm, before assuming various other poses while saying various lines she's heard from various hentais like 'Please be gentle Senpai~', 'Pound this naughty kitten Senpai!~', 'My tits feel wierd Senpai, wont you relieve them?~' or 'Please don't send me to jail officer! I'll do anything for you! You can even use my body however you want!', though the last one held a sort-of special place in her heart, being the line that lead to the catgirl burglar being dumped cum-drenched and twitching into a dumpster. Afterwhich Nyarla tried out a variety of different expressions, particularly an ahegao face and a pleading sort of face, to say Nyarla was caught off guard at how 𝘨𝘦𝘯𝘶𝘪𝘯𝘦 a expression of puppy-dog-eyes she could do felt like an understatement that only added a secret weapon to her arsenal of 'how to get fucked'.
Satisfied at at her body and form Nyarla began to wonder what to do now.
