Mathias slowly came to. He was disoriented for a few moments as he woke up in the undamiliar enviroment, before he remembered where he were. This is the gender alteration clinic, and he, or, um, she was supposed to be a girl now.
Excited and Nervous, Mathias shot up from the bed. She barely kept her balance as she landed on her feet. She looked down at herself, her chest obstructing much of her view. Weird. She'd selected for her new self to lean less feminine, so she'd expected smaller breasts that this. These were huge. Mathias touched them, and immediately let out a girly yelp. They were sensitive.
She tried getting a look at the rest of her body. Thin arms, flaring hips leading to a tiny pair of feet. It did seem very much stereotypically feminine.
She grabbed her phone and viewed herself in selfie-mode. Large expressive eyes, a small button nose, pouty lips, and soft features in general.
Something had gone wrong. That was obvious. She just hoped everything else had gone as she'd wanted. While she'd intended to be a little more masculine, having a bit of a tomboy look, it wasn't a disaster that she'd ended up as feminine girl she hoped. At least for now, she was getting massively turned on. She made flirty expressions into her camera, and was fixated on how cute she looked. She wanted to explore herself further, but she ought to check what went wrong first.
She got properly dressed. Her old clothes didn't fit at all, the most significant thing being her clothes being way too long for her, revealing that she'd ended up as a tiny thing. She used the interface in the room to get some basic clothes.
She returned to the reception. She explained her problem. It got revealed that it was a mistake of Mathias'. She'd just filled the form out wrong. Oops. Atleast everything else was as she wanted it.
Mathias left the clinic. She hurried home, wanting herself naked and in private as soon as possible.
