Cute in Plastic (Pigtail Penalties #3)
Amy Estes

Because she enjoys having him under her thumb, Nadia decides to keep him in the body of a pretty girl, subjugated and tamed. But she craves more than simple control. She wants to make sure Jarod never forgets “her” place. Nadia diapers Jarod, she dresses him up as her maid, and then she puts him on display. All of his former friends are going to get to see him in his new body. They’re going to spank him, play with him, and order him around.
Ultimately, he’ll get one chance to become a man again. If he can’t, he’ll be their diapered girl forever.
This fantasy short contains explicit content. This is the story of a gender swap/regression punishment. It also features group spanking, public humiliation, maid service, and diapering. All characters are consenting adults.
