One thing among the many other things he'd dreamt about making real was his ideal version of himself, and now that he had the power, the will and the opportunity, Jay could finally achieve it. And so was it that he, Jay, wrote into the Chronivac for him to become Jayann, his idealized anime-girl body, after a 5 second timer. And on hitting enter, Jay rose from his desk and shuffled aside his chair, excited and expectant for when the 5-seconds went.
The changes started suddenly, making Jay double over as he felt a sharp, relentless, tugging down below that nonetheless made him moan from the background sensation of pleasure. Every sharp tug, and every resultant moan (tiny as they were), made Jay exceedingly aware of his rapidly shrinking manhood, and the feeling of his shifting internals. The tugs ending abruptly on the tenth, simultaneaous with a sharp 𝘴𝘱𝘭𝘪𝘵𝘵𝘪𝘯𝘨 sensation in his stomach as his womb and ovaries formed and connected to her newly-formed virgins vagina.
And with the complete switch of her sex, the rest of her form began to follow into the domain of womanhood, her male skin shedding itself of any imperfections simultaneaous with all her bodily hair also disappearing, the only hair remaining being her head-hair, eyelashes and eyebrows (which had becoming more defined and anime-like). Following it, her skin turned smooth as silk, gaining the feel of skin thats been lovingly, tenderly cared for to perfection each and every day. Her hair turned the colour of blue sapphire as it loosened up into a pristine, lovingly cared-for waterfall of sapphire hair, reaching down to her thighs with strands of soft, exquisitely tender sapphire coloured hair.
Next, her form slimmed and shrunk, the 5'9" 15-year-old shrinking by 5 inches as her body lost any visible muscles while also slimming down into a lithe form, her hands and feet becoming daint and girly with primly manicured nails. After her body slimmed itself of any mass, becoming the form of a girl absent of the defining features of femininity, her face topped it off with becoming round, cute and girly, her eyes becoming large and expressive with pupils the colour of the deep sea, with lips plump and luscious yet not overly apparent.
With everything else done, her body moved onto the final stage, namely giving her her curves. Which it kicked off by summoning all the removed mass and depositing them into her two buttcheeks, hips, and thighs, making all three items large and juicy, a little bit more serving to firm them up into a pleasant bottom of an hourglass curve. Followed thereafter by her waist trimming down until it was narrower, pushing the liberated mass upward into two measly B-cup mounds, followed by the Chronivac dumping newly created mass into the two hills, making them jump for measly mounds to titanic melon-sized tits larger than her head in less than a second. The sudden 'Bwomph!' and consequent 'Oooh!' making her stand up straight as two mountains suddenly rocketed forth in a comedic fashion.
And right after all that, reality abruptly changed, Jay's room turning into Jayanns room, its items changing to ones more appropriate for a anime-girl to have, though the anime parapharnelia remained mostly untouched, this reality's Jay also being a massive anime-fan (Jay did often fantasize of Jayann in cosplay after all), of most immediate concern for Jayann, was her clothing, which had changed into the outfit Jay had most often envisioned Jayann in. Namely, she was now wearing a comfy dark-gray sweater that fully covered her firm sea-blue bra and torso while nicely outlining her huge mammaries, a black skirt hid her dark-blue panties and covered her behind, creeping down her thighs while stockings hugged her exposed legs.
Jayann, giddy with joy at these developments, quickly found a mirror and inspected herself, excitement bubbling up from seeing the Chronivac so easily catching the beauty of her desires and giving it to her in the perfect way. A stray thought that wondered how she'd look in other outfits sent Jayann just about bouncing over to her closets, that she got to find out how it felt like to have tits that bounced to your every step just added to her bubbling joy. And much to her excitement she found her closets chock full of different outfits to choose from, from a variety of schoolgirl outfits, various sailor uniforms, plenty of comfy outfits with various sweaters, plenty outfits which were practically meant to show off most of her skin, gymnastics outfits with sports uniforms, outfits for when you're taking a stroll through the city either at day- or night-time, plenty of onepiece and two-piece swimsuits, various outfits she instinctively 𝘬𝘯𝘦𝘸 were cosplays, various dresses, various fancy outfits which included one or more sets of impossible-clothing (despite being 'impossible' she can get them on through the power of anime-logic handwaving), Various chinese dresses like the Cheongsam, various japanese Kimonos and Yukatas including various fashions of Shrine-maiden outfits, various miscellanious outfits and most important of all were the numerous maid uniforms together with multiple bunnygirl outfits. at the bottom of each closet were the drawers for the various other things Jayann needed as a girl, with one closet drawer used for her bra's, panties and such while the other was filled with various accessories like hairclips, hairbands, hair-ornaments, bracelets, bunny-ear hairbands, cat-ear hairbands, etc.
Jayann practically vibrated on the spot with excitement and the intense desire to try on every one of her outfits right then and there, but a glance in the direction of the chronivac made her pause, and reluctantly decide that dress-up can wait atleast a little while and went to ponder what to do as she walked back to her computer which still showed the user interface for the Chronivac after she'd first made himself into his ideal anime-girl Jayann. Sitting down into her comfy seat and feeling her butt squish some against her comfy stools cushion, Jayann went and looked through the Chronivacs wide variety of options semi-indecisively for some 10 seconds, before deciding on what to do.
