Talya was a close friend of yours....

 

Talya was a close friend of yours and a talented thief. With her natural agility, slight frame, and short height Talya was able to get in and out of anywhere. She would often bring you rare materials allowing you to craft all kinds of equipment for other adventurers. You knew though that thieving was a life forced upon her, the result of her half-beast nature.

Early in life she was the target of man assassins who feared her going 'feral'. First, her blood was that of a famous chimera which are creatures known for especially violent mutations brought on by puberty. Second the chimera in question had made a pact with a demon granting further enhancing their powers and poisoning the bloodline.

Talya had just turned 18, you should have been more prepared, but you had dulled your senses with years of peaceful civilian living. This is why you hadnt noticed Talya lying in wait.

Just as you fired up the kiln you caught a glimpse of a shadow and then--

--BAM!

In an instant you were on the floor, you should have been dead but your attacker had used a blunt weapon. In haste you rolled onto your back to defend against a followup. What you received instead was a pleading gaze on an all too familiar face.

‘Talya? what the hell was that for?!’

‘Didn't mean to-cant stop it! G-oing ferral.. dont wanna go crazy! Not like others!’

So it was finally happening, she was going feral and in your blacksmith of all places.

Talya head began listing to the side, while she clung for dear life to the tables for support.

‘Talya! Talya!’ you cried

'Came here-safe with you. Trust you.' Talya's breathing was becoming more labored, her expression filled with pain.

'Talya what should I do? Should I get a healer?'

It was no use, her mouth hung open but all that came out was babble. Your eyes met for just a moment, but then her's grew as wide as saucers, pupil rolling up into her head. Talya was no longer there.

Slowly her tiny frame began pulsing. With each ragged moan that escaped her lips, her body grew larger and larger. Mighty sheets of globular muscle mass push lats outwards, while bulbous mass piled on her lithe limbs. In mere moments she had biceps as big as yours, the next even larger. Not to be outdone, her lower body had kept pace and now sported two heavy quads and thick calves that fought against ever larger hamstrings.

The female rouge moans became huskier, deeper as her voice changed. Her once respectable bust was now thoroughly diminished by her powerful curves. This was emphasize by her still expanding traps and lats who were close to tearing her top off. 

Then it came, the terrifying roar that was of neither a mouse or a beast, but that of a demon!

GRAAAAAH!!!! 

Her roar signaled a new stage of growth. Thick horns sprouted from her head, curling back while others forward. Her new crown's growth sent spasms and shockwaves right down to her loins. It was then that you spied her two lower additions.

Where a smooth crotch should have been were two fourteen inch monsters, thick as soda cans and leaking more pre-cum then a most men's loads. They say when beasts go feral, everything changes. Now you know what they mean’t by everything.

‘No-n-moar!’

Talya was coherent again but unable to control herself as her cocks twitched rhythmically, fueling more growth. Despite her heavy body mass, thick finger width veins coiled to the surface on her extremities. The vascular network throbbed and rose becoming three dimensional.  The veins then slowly faded to blue as the mutant network faded under her porcelain skin.
