Milly felt conflicted. Still not sure if it was really morally right to potentially doom someone to an existence as a blob, even if according to the other girls reality would change to accommodate them and they could revert them later. Because of this she was somewhat half-hearted in her search for potential targets.
After only 10 minutes Milly came to the decision to just use herself as the subject for this round. And weirdly enough, she didn't mind it as much as she expected. Technically this wasn't even her body after all. The whole bodyswap romp with the dildo had started to give her a whole new outlook on the concept of bodies, souls and appearances. There hadn't been a reason to change her name to Milly, except it somehow felt right. Did that mean she was a woman deep down? More food for later thoughts, now she had a game to win.
Making herself comfortable on a grass patch in a park she started stroking her long dick while pumping her own tail in-and-out of the vagina that had opened below the penis. It didn't take long for her to come with this double stimulation and start her own transformation. Milly was getting giddy when she felt the first tinglings of the transformation start. It was an open secret that she loved the feeling of being transformed. It was the main reason she offered herself to become Carmen’s ass in the first place.
Her first change was for all her hair on her head and tail to turn a bright sky blue. The catgirl was almost disappointed for a moment, when suddenly her gut started expanding. And expanding it did. As her stomach filled out to become an ever-growing sphere, Milly felt the rest of her body sinking into it. Soon only a perfectly round, featureless sphere of flesh was left that continued its growth until it reached a diameter of about 12 feet.
A moment later the flesh sphere shuddered and four cat legs in sky blue fur grew out of its underside at four corners. On the upper side a small head emerged with big black eyes and blue hair and cat ears, but no mouth, between two big, blue cat ears. On what would be its backside a giant vagina opened up and right above it three growths emerged. The one in the middle soon became a long, feline penis, while the two tails flanking it grew blue fur as well as big cat paws at their ends.
On the opposite side, therefore the front side, two big, blue, inverted nipples appeared on the upper half, almost looking like eyes from afar. The final, but most important addition followed right after. A large, jagged line started almost completely bisecting the sphere into an upper and lower half, only stopping a bit shy of the vagina to not cross with it.
The giant mouth opened up to reveal the inside of the flesh sphere to be almost entirely hollow. The only feature, a copy of Milly’s body (before ballooning out) growing out of the back wall. She kept the blue hair and even had her own set of hermaphrodite genitalia, but she had neither arms or legs.
Milly took a moment to reacquaint herself with her new body. If she had to describe it, it was somewhat of a mix of a venus fly trap for humans and a cat. She really loved how it perfectly encapsulated her recent thoughts about bodies and souls. A weird, almost grotesque, outer body, that looked like a four-legged giant head with genitals and a small head on top (through which she saw the outside world when the mouth was closed), and hidden inside was a beautiful maiden.
While thinking Milly scratched her chin with one of the paw-tipped cat tails, which alongside the penis could stretch deceptively long. She easily could use it to pull something, or someone, into her giant mouth. Of course she was already looking forward to spending some private time with Carmen inside her outer body, assuming she didn't grow even larger.
Closing its giant mouth for now, this weird, cat-legged creature made its way back to the meeting point. She was already looking forward to presenting everyone her body and hopefully winning this round.
