Steven Goes To Nursery School: An ABDL Short story

Mrs. Crawford just couldn't understand what had gotten into her eighteen-year-old son, Steven. A few months ago, she had caught him wearing one of his baby brother's diapers. She had hoped to cure him of his odd behavior by dressing him and treating him like a little baby for the rest of the day, and she had thought that she had shamed him out of his desire to wear his brother's diapers. But to no avail.

Would a Nursery School help?
