Is There a Specific Term For Stories of Young Women Getting Corporally Re-parented Sans Sex?

There seems to be, but I wanted to ask.

To clarify, the girl in question is typically in her early twenties, entering college, or at most, just out of college, and she finds a domineering mother figure whom she is drawn to, leading to spankings and some version of a second childhood, often because said young woman is ill-disciplined, and poorly behaved, although I don't really like stories where she is poorly behaving to begin with, at least not intentionally; I like stories where she is a good girl, but is shy and insecure, and the domineering mother figure offers something she can't help but desire, losing freedom not as a punishment, but instead because she craves what it offers more even if it means losing her independence and all that entails.

I don’t know if there’s a term for them but I really like those stories.

You'd probably like ebooks by Pet Jeffery who often writes on a theme of age regression, typically with a woman of around 24 years but who looks and acts younger, who is befriended by a strong-minded older lady who dispenses spankings along with tea and biscuits, selfless care and discipline. The young woman learns to re-experience and enjoy her teenage years properly, and CP has a part to play.

Like Katie, I don’t know if there’s a specific term, but I also enjoy those sort of stories.

"Terri goes back to her Teens" is a favorite; spanking itself does not interest me, but the role reversal, and mind games. For some reason, though, the rest of his stories do not seem to interest me; when the punishment is fully consensual it ceases to be punishment, and that doesn't impress. Also, if the girl is acting out of control prior to spanking, it diminishes the theme of losing power, given she never had any to start out with, and the punishment ceases to be an exercise of power, but mere justice, and that's not erotic. If the punishment far outstrips the crime, though, it is erotic, and if her abuse of independence leads to perpetual pain and humiliation she can't escape but wishes to, well, that's interesting; sex itself in that case is unnecessary. Know any stories like that?

Beyond that, know any good undercover stories? I like stories where a woman goes undercover, and gets struck in that lifestyle, but most stories with that setup get unfinished before really delving into it. Maybe that is innately telling.

I've done a few as well.
"Returning to..." and "Returning To... An Artist's Tale" are set in a world where adult daughters are moving returning home and being subjected to corporal punishment from their parents. It was written during the Great Recession so it's a dated.

Let's see.
Christmas Across The County Line - set in weird future, it involves a college girl spending Christmas in a county where any girl under 21 can be spanked.
Adventures In VR - Nancy Drew - college aged girls using a virtual reality system to become Nancy Drew and friends.
Boning Up For Psyc 103 - a college girl needs to know more about corporal punishment to write an assignment.
A Good Hand Spanking - a college girl staying with a neighbour over the Christmas Break.
Home For Christmas - a college girl gets spanked by a neighbour.
Jennifer to Jenny - a college girl dresses like a young girl for Halloween
Out For A Lark - a pair of college students do an acting exercise where one plays the Uncle and the other his Niece.
Legal Problem At The Beach - a college girl is "mistaken" for a young teen after she loses her ID at the beach.
Susan Woolcraft - a college girl is trapped by a storm and sleeps over with the pro-spanking parents of a friend - a friend who didn't come home for the holidays.
The Reporter - a woman reporter uses magic to look like a schoolgirl to do a story on a private school for girls.
Sneaking Home - a college girl tries to get home for the holidays by pretending to be young enough for a child's ticket.
A Visit To A Foreign School - a college girl visits her aunt, who works at a school where corporal punishment is used.
The Wrong Cousin Vikki - a college girl named Victoria is mistaken for a much younger cousin named Vikki.

I hope you enjoy these.

The term I think you're looking for is "age regression."

The trouble with any catchphrase is that it becomes an umbrella term for many different things. Meaning you'll still likely need to sift through various story concepts not to your specific tastes before you find the right ones.

Age regression can vary: from willingly to being forced, from reality (merely dressing like the younger age) to fantasy (actual physical regression while retaining adult mentality), and lastly the age range may be toddler to late teens.

"Willingly" being a subjective term, as someone might need to adopt a younger pretense to "hide from the mob" for instance. So, willingly, but at the same time, forced.

ive started on just such a series but haven't worked on it in ages. Not sure if I will or not. But it is there.

I haven't seen a formal term but the phrase 'back to her teens' or some variation comes up in either title or description of many of the stories I've run across.
