"You live in a dangerous neighborhood. I really think that you should get some protection," someone says in a nearby aisle. As though being controlled like a video game character, Leah walks into the clothes section, veers off into an adjacent aisle, and grabs a pack of diapers in her size. She then returns to the clothes section and finds herself able to move around under her own volition again. But she can't put the diapers back or even set them down. And she has a feeling that when she goes to change, she'll be unable to resist putting one of the diapers on.
With a sigh, Leah grabs an outfit that should fit over the diaper without a visible bulge: a long, brown, high-waisted skirt and patterned dark red crop top. She also grabs some underwear, just in case she's able to wear them instead.
Leah walks to the register in the clothing section, buys her new items, and makes a beeline for the bathroom. As she suspected, once she pulls off her soiled clothes and cleans up, her body moves of its own accord. She tapes on a diaper and...huh. The sensation of wearing it isn't as bad as she expected. She'd prefer actual underwear, but it won't be impossible for her to go about her day in a diaper. Hopefully whatever is going on with her won't last. She's stopped sucking her thumb, for one thing.
To Leah's relief, her skirt doesn't display any sort of diaper bulge. And her outfit is really cute. She could get used to it. Leah throws her soiled clothes into the trash, leaves the diapers behind, and exits the bathroom to find Tina. Hopefully she can come up with some sort of lie to explain away her clothes change before she finds her stepmother.
