You see an option down further down labelled leopard. Pushing this a small display illuminates.
It has a spinning wire frame of a anthropomorphic feline, one with a plump feminine figure - rather like the doll with whom you had just met.
Adjusting a few sliders, you slim down the anthro cats build. Very long legged, keeping the large paws, the creature would be a heck of a runner. Thick thighs, flared hips, and a bubble butt added some girlishness to the lower body.
This tapers to a narrow waist. A few touches of the slider shrink down the torso and narrow the shoulders. You pause, then tap another slider, shrinking in the waist a bit more.
The slider for breast size has a minimum of a D cup, which is where you leave it (not that you'll ever actually wear a bra after this).
A few more touches reshapes the handpaws down to a less cartoony proportion. The short fat fingers stretch to long slender feminine digits, though still tipped with retractable claws. You keep the paw pads though, can't be too human.
The face doesn't need much adjustment, it is a perfect blend of human and feline (heavier on the feline with the full muzzle and adjustments to skull shape to accommodate).
Clicking the color display, you select silver for the primary and white for the secondary. The spinning figure fills in as silver on its back, sides, and limbs. White covers from the featureless crotch, up the belly and chest, over the throat, ending with a white muzzle. White also extended down the underside of the feline's tail. Inspecting the tail, you add more length and thickness. The stats show a diameter of six inches and a length of four feet.
Tapping a bright aqua blue for accent color, you see the rosettes on the leopard render in this shade. The claw tips, lips, eyes, and even the tip of its tail also fill in with this color. You like the way this stands out against the silver.
You strip down and put your clothing in a box provided for this purpose.
Nodding with approval, you press the big red button.
You feel light headed, and numb. It's like your whole body has fallen asleep. You can vaguely feel things moving, reshaping. The sight of your lower face pushing further into view as your muzzle forms is disconcerting, and you close your eyes. The disorientation ramps up as your mind is flooded with what feels like a lifetime of knowledge and fuzzy almost memories.
With an abruptness it all stops.
You marvel at the perfect silence. All your life there has been the subtle background noise of your breathing and pulse, though you never noticed it until now when it is gone.
You step out of the chamber, effortlessly balancing on your long feline digitigrade legs. It is as if you have been like this your entire life, which in a way you have.
You know all about your new self and body. You know this because of how the machine functions. It works on the concept of multiple universes. Once a new doll is designed by the user, the device finds where that doll already exists in another universe, and transdimensionally entangles the person and the doll.
You know everything the doll knew, because the doll is now also you. You know the shiny rubber/plastic of your skin is a nearly indestructible polymer that is also a direct thermocouple, powering you from the heat of the surrounding air. Most of your interior is an exotic aerogel material that is both a battery and artifical muscle, while weighing much less than water. Your brain is now a self repairing crystalline lattice.
You smile at the cleverness of the device's creator. They didn't need to invent the fantastic technologies that made the dolls possible, the device went out and found a reality where the hard work was already done.
The pink cat smiles as you stride over. Your long legs and long tail give you a hypnotic bounce and sway that you know many will enjoy watching. This makes you happy, you exist to help others and improve their quality of life.
The pink cat gives you a hug, her ample chest pressing against your bare smooth stomach. You are now much taller than her, your ear tips touching six and a half feet. Your skin is extremely sensitive, and the embrace feels very nice. You are definitely not some emotionless machine, her unconditional sisterly love touches you deeply.
'Our placement service has found a high percentage match for you, someone we believe you will be very well suited to serve.'
You nod. While you are technically not property and have free will, you know at your core you need to have a master or mistress. To serve someone and be their assistant and companion.
You walk back to the office, not a thought more about your new body and nudity. You are a doll, sexless and servile. Your clothing and personal effects remain in the chamber, now unneeded and forgotten.
