Disclaimers~
*this is completely sfw so if you're looking for smut or any kind of kink go find a different story
*Although this story is safe I wouldn't recommend it to anyone under 13/14 because it is an age regression story
*I do not own any of these characters except Rosie and her mother. All credit goes to Jk Rowling even though she's a transphobic biatch
