Sophie Dirty Diaper Regression

Doctor Sophie has made a significant discovery: a youth serum. She plans to take full credit for it, despite her assistant, Anya, having contributed most of the work. Feeling unappreciated, Anya decides to retaliate by secretly administering an excessive dose of the serum to Sophie.

After consuming the potion, Sophie quickly begins to experience its effects. She becomes dizzy, her voice alters to that of a child, and she struggles to maintain her balance. Ultimately, she collapses and is unable to stand or sit up. Anya revels in her triumph as Sophie loses her adult capabilities, unable to articulate her distress and instead babbling like an infant.

As the situation escalates, Sophie soils herself, leading to further humiliation as Anya teases her. However, Anya eventually shows compassion and cleans Sophie, changing her into fresh diapers. From that point onward, Sophie requires care akin to that of a child.
