Transformation curse

Curses that embarrass the poor nudists through transformation into something different, animals primarily. The general idea is somewhat like an animagus from the Harry Potter series or like a werewolf, but isn’t yet controllable. Anyways, your choices are(but not limited to):

Heather who turns into random animals at random times, whether she transforms when she’s naked or not doesn’t matter, she still transforms back just as nude as she would’ve been. She, personally, is sweet and shy. Physically, she is a brunette with a few black accents in there and her body, although looking really good everywhere else, gave its best to the boobs.

Chloe who turns into a human animal hybrid like a Neko or a werewolf. The transformation often tears up or shrinks her out of her clothes, leading to various embarrassing encounters. Her transformation occurs every night as soon as the sun goes down. Unfortunately for the dirty blonde haired woman, she has a number of friends and/or busy activities on certain nights

Tracy who, when emotionally activated by her crushes, shapeshifter her body into a prime form of a sexy lady. The process puts on a countdown to where her clothes will slowly shrink and eventually evaporate. Thing is, her classes are usually involve her partnering up with someone she likes. Her hair color varies time to time because of the transformation. Her normal form is a regular build, c cup, blonde girl with somewhat toned skin.

Feel free to add on any other types of transformation curse and girl
