Pretty sure I've written this before, but shapeshifters being forced into body modding

>Shapeshifters are captured and used for all manner of wicked things
>Including cock transformation
>They transform through their will, but must retain their minds so as not to cease being
>Thus their will needs to be broken for them to be controlled
>They are drugged and hypnotised
>From there they will be fucked and told they are nothing by a cock
>Conditioned to respond to a vibrating collar around their neck
>They are shown the anatomy of a cock to the specifics of their soon to be host
>Eventually they will break
>Once they succumb to the notion, losing themselves in the pleasure, their body does the rest
>Bones melt away and muscles become soft
>Organs repurpose themselves as sexual anatomy
>Their body merges into the host
>When at last they have become the desired shape, their collar is deactivated
>This sends the signal to the shapeshifter's brain, still present at this point
>The signal that they are complete
>Then the brain itself will wither away
>If they are lucky, it may persist as a vestigial nerve cluster
>Having lost their memory of the conditioning of the collar before their mind was completely wiped away
>Though their consciousness will be minor
>They'll have forgotten what they once were, not knowing that if their will was strong enough they could return to it
>From their reduced point of view they are a cock, always were a cock, and always will be a cock
>Why would they try to change?
>The life of a cock is simple and full of pleasure

Granted! Pardon my interpretation since it's hard to tell EXACTLY what's going on here, but I think what I will give you is more than related enough to e passable.

Whenever you are alone next, your flesh will mutate into a pile of sex parts and organs of various shapes and sizes. Lots of testicles, breasts, ovaries, as well as pussy mounts and even dicks. You'll quickly become an unrecognizable mass of spare flesh and cumming genitals... which, despite your lack of eyes once it's done, seem more than random, but almost intentionally specific...

By this point, your wish is concluded and you're CERTAINLY enjoying yourself... and, well, it's not like you can refuse what I'm about to propose. I like to recycle. Sure, I'll keep your body somewhere safe where no one can find it, make it immortal even, but you're STILL growing these sex parts, and it's not like you need ALL of them, right? And so many wishes I grant call for extra dicks, boobs, balls...

So congrats, you're now a source of fuckmeat if I ever need to alter someone. Dickgirl? Well it just so happens you grew the exact package I was looking for. Did I plan this? Pfft... well yeah, but what are you gonna do about it? Bigger, or extra breasts? You've got those. Another pussy for some taur tf? I'll just take this mound here...

Oh right, what happens to your mind now. I mean, your brain was transformed too, but this wish made you effectively immortal. Your main body doesn't follow any laws of biology to stay alive, so your consciousness and "soul" reside in the parts I'm using. You'll experience being the ass, pussy, package, boobs, etc of every cute girl or futa monstrosity someone wishes to become... but not all at once.

I don't know why, maybe it's your mind's way of keeping you "sane", but you'll experience each of these lives individually, sometimes out of order, sometimes even swapping from one, to another, and eventually, back where you left off in another life as some bimbo's puffy pussy.
