transformation Punished into becoming a pig girl

WARNING: Weight gain, transformation, hairs, dumbification.

This is set in my crappy fantasy universe of which I'm still writing the lore.

Pig beasts in this world are former humans that have been punished for crimes usually associated to ones of gluttony. They are transformed by the ruler's personal sorcerer.

Their bodies are fairly human, at least their torso is. Their limbs are shorter than human ones, their crotch is covered in rough hairs, same thing for their armpits. They are naturally plump, but some skinnier specimens exist.

Their brains is reduced to a smaller, simpler one, and they are purposely made to be constantly hungry and horny, as they are often used as either breeding sows for butchers to use when their pigsties are empty or as either left overs eaters or garbage consumers.

Log of the first punishment.

20 of June, year 1273. The prisoner has arrived. Chained to the wall and blindfolded, stripped to her undergarments.
Her body, lean, somewhat muscular. Her face, pretty, with a large scar of what looks like a blade that makes its way across her left cheek.
The sorcerer, arrives, he is hooded, his face covered with countless tattoos. From his baggy hood he grabs a vial, the liquid is green, and quite cloudy.
He walks in front of the prisoner, and removes her blindfold. Her mouth , opening, her teeth, sharp, even if a bit jagged.
She tries to bite the man that will soon morph her. But it is of no avail.

" Free me, you bastards, I have done nothing worthy of punishment "
She shouts, looking around at the crowd that had now formed around the town square, where those who had commited a crime where punished every Sunday.

The hooded man gets close once again and throws the vial on the prisoner's face, the glass breaks, making small wounds on her body, where the glass landed.

" One does not end up in this situation if she hasn't done anything worthy of punishment. You are lucky for not ending up with a rope around your neck"
Grinning, he backs away, staring at the prisoner as her body starts to shake, she starts looking around, staring at the crowd, then at the hooded man.

"By stealing from the local bakery, you have offended the gods. The punishment you have been subjected to is taking the form that best suits you."
The crowd starts cheering for the gods, kneeling and then praying. While the punished one is starting to change.

Her body, starts to swell up, her muscles, clearly being replaced with soft fat. Her once flat stomach now lays on her thighs, her long, toned legs, shortening and becoming soft, losing all the muscles on them. Her perky chest, getting larger, sagging, now laying above her deep belly button.
Crotch and armpits, now covered in rough looking hair.
And her face, had now been disfigured by a large, flat snout and large pink ears hanging on the sides of her face.

Her expression had now morphed into one that only an imbecile could have. Gaping mouth, tongue out, drooling.
