"That's alright with me. Thank you for asking, though."

A cascading beam of soft swirling light wraps around her, and teleports her away to a new room. 

The room looks largely like a normal doctor's office - with the only real differences being a replicator inset into one wall, a standing desk with a LCARS style console inset, and a mesh of wires that takes up much of one wall. 

"Hello, hello. You must be Vivian. I'm doctor Gen, and I will be the overseeing physician for your body refit." 

He extends out his hand with a congenial smile. 

She shakes his hand, mostly on autopilot. "So," she says. "How does this work, exactly?"

"Right to the point, then!" 

He nods his head enthusiastically. 

"Presuming that you're just looking to stay human, it's a relatively simple process. From your perspective, you should simply be sedated and wake up fresh as a babe, and ready to go on your merry way! There's a variety of authorized methodologies, but the one that I'm expecting to use is an injection of a nifty bit of nanotechnology that will reconfigure your biology down to the genetic level to your desired state. We can readily adjust your physical form towards anything reasonably plausible within the bounds of humanity, but for safety reasons broader neurological work beyond helping you adjust to your new body is out of scope for the procedure. Still, there's a bit of wiggle room left in the hormone modification process that allows for a little bit of tweaking, if you so desire." 

"Alright. Uh, is there like a neural interface I can mesh with to share my ideal human form with you, or do I have to use my words —" like a good girl "— and communicate the details verbally?"

"Such technology exists! Unforunately, it's not the most reliable with untrained subjects. Customarily, a form would be customized and altered in holographic form, we would discuss any non-visible alterations that you were looking for, and the final body reconfiguration process would use a combination of the form I devised based on your recommendations and your mental input, to avoid more problematic deviations." 

"Alright, then." Vivian smiles. "Honestly I feel I'd be contented with almost any reasonably feminine body, but, well, I do have one or two requests..."

She crosses her arms over her body. "Let me see. Naturally purple hair would be nice. I'd like to keep my height. Given that we're going to be taking this into service making the new body reasonably fit and healthy just makes sense. I have chronic acid reflux from eating too many cheese buns at university, and my right ankle sometimes gives me joint pain, but otherwise the body is pretty much fine... I'm a little attached to being myopic but I think going into a danger zone it'd be better to not need glasses. Otherwise..." she purses her lips. "Something relatively modest? I don't especially want to draw the eye, but neither do I want to be plain."

He hums softly. 

"A common starting point is a 'bugfixed' 'direct' natal sex swap... Let's try that." 

He pokes at his console, and a hologram shimmers into existence, before shifting again. It has a fairly similar general frame, with the muscle of a runner, b-cup breasts and wine-purple hair that could pass for a rich black at a distance. Her face isn't quite plain persay, but it is a little unremarkable.  

She smiles softly, looking at the version of herself up on the podium. 

"That's not so bad. Could maybe use something in the cheekbone department and a slightly larger... bosom. The shoulder to waist ratio is maybe a little off too."

He obligingly pokes at his console a little, and gives it a bit more of a defined cheekbone and a bit of a general sleeker look in the face, alongside a pair of breasts at around low-D and slightly firmer shoulders and wider hips. It makes the overall look a little bit more exaggerated and eye drawing, but not much more so then you'd expect in a gym regular. 

"Not bad..." She smiles. "I like it. Um... can I ask for a natural "tattoo" on my... let's say right shoulder. Of a rose. I never had the courage to mark up this body, what with the health and class implications, but I'd like to be a little bolder in my new life."

He hums. 

"I can give a birthmark of that approximate shape, or alternatively a conventional tattoo?" 

"A conventional tattoo would be fine."

He nods. 

A while later, two different designs shimmer into place on each of the holograms shoulders. 

"Your thoughts?"

"Closer to the first than to the second in area covered, but I'd like the individual blossoms to be smaller."

He adjusts it, adding a third blossom and managing the proportions to fit the same 'frame'.

Vivian smiles, already a little besotted with her new form. "Looks lovely. I think I'm satisfied."

He claps his hands together with a bright smile. 

"Alright then! If you'd please make yourself comfortable on the bed, I can start as soon as you'd like." 

He reaches down, and pops up a case, drawing out a hypospray. 

She takes a deep breath, and lays down. 

Here goes nothing, she guesses.

He walks over. 

"You'll feel a brief touch on your shoulder, then you should fall unconscious within a second or two. Are you ready?"

She nods. "As ready as I'll ever be." 

He reaches his arm out, hangs the hypospray above her shoulder, and there's the faint hiss. 

In mere moments, she falls deep asleep. 

When she wakes up, her body has been changed and dressed in a soft white hospital robe. Doctor Gen is there, fingers plicking against the console, watching and waiting. 

She looks down at herself...

... and takes it all in. 

She's in her proper body, now. She's free. 

She practically hops up from the slab —

— almost overbalances because her center of mass isn't where she expects —
