Monica, Emilia and Sarah were excited when a transformation center opened in their town, but Emilia and Sarah waited some months for Monica to turn 18, to be fully in control of themselves, celebrating Monica's birthday going to the zone to transform themselves.
They went at night, it was in a mall like any other shop as animal transformations got common and normalized, they entered the center looking very similar to a hospital inside, looking at some transformed people and normal people waiting for their turn in a line, fortunately it wasn't long so they waited for their turn and received a ticket to enter the transformation room.
"Okay okay! Who will go first?" Said Sarah happily excited holding hard her ticket with a big smile printed on her face.
"You seem really excited, you should go" Monica told her.
"Omg, thank you!" She ran to the transformation room, Emilia rolling her eyes as she smiled.
"What do you think she would transform into?" Emilia asked her friend.
"She looks very excited but we know she would pick something really basic" Monica replied.
The door opened again, revealing Sarah completely naked with a pair of cat ears, a white fluffy fur covering her neck, a cat tail attached to her ass, cat paws replacing her old human feet. Looking up they noticed that her face had feline traits and cat whiskers.
"I told ya! And it seems that she made her flat chest bigger" Monica said looking at the pair of breast Sarah held that went to A cups to E cups.
"You have the option to transform into anything you want and you went for that? Not that I'm complaining but overrated for my taste" Emilia said.
"Aw come on girls, It's the new fashion! I love this new assets" Sarah stroked her fluffy tail and grabbed of her boobs.
"You should love them, not that you could remove them" Emilia giggled.
"Why don't you show us what a real 'transformation' is, Ms. I hate everything" Sarah tested her.
"Well, let me show you" Emilia entered the room.
"Calm down she's maybe nervous for this thing, she will get over it later" Monica put her hand on Sarah's shoulder as she waited for the door to open with a frowning expresion. It took Emilia a slightly bigger time to exit the room and reveal her new self.
Emilia was now an anthropomorphic hyena, with a busty figure having six pairs of nipples below her tits, with her characteristic female hyena cock in her crotch connected with her vagina.
"What do you think of me now" Emilia stuck out her tongue smiling as she slowly stroked her cock.
"Well, you look great... That dick thing is a little bit odd" Sarah said pointing at the new gift between her friend's legs.
"You look amazing! That was kinda creative" Monica clapped.
"I know, I know, thanks!" Emilia happily said, "now it's your turn birthday girl!" Emilia said.
"Yes! I want to see what do you have in mind" Sarah followed.
"Sure, I'll leave your mouths open when you see me!" Monica entered the room.
The inside looked way bigger than she expected, having many booths like changing rooms in a clothes store, both each booth was a chamber with the side of an elephant with automatic door. One of the rooms opened, looking how a half giraffe half horse woman exited, Monica nervously greeted her as she entered the the chamber, closing the automatic door and waiting for her transformation.
Now inside she began to undress, leaving her clothes that probably she would never use again after that moment, looking a board in front of her with many buttons, having options like feral or anthro, specific body parts and all the animals she could imagine. She wanted to transform into something decent, but now with all that options she couldn't decide drowning in her thoughts of what animal, part animal or whatever she could become. After thinking really hard for some minutes she pressed the buttons of her transformation.
