"Well, what kind of diapers have you and Tonya been putting me in?" Leah asks.
"Baby diapers."
"Really? Those fit me?" Leah shrugs. "All right, I guess we can keep using those. I haven't had any leaks in them."
"And in terms of them being obvious..." Tina says hesitantly.
"They're not very obvious when I wear flared skirts," Leah says. Tina nods. The flare of the skirt conceals any sort of diaper bulge. "My school uniform is a flared skirt. I think that should work out all right." Leah chuckles. "I never thought I'd be happy I went to Catholic school."
"Are you sure you're comfortable using your diapers openly at school?" Tina presses.
"I can be discreet."
"Even when you poop?" Tina points out. Leah frowns. Even without the smell, it is usually obvious what she's doing when she's pooping.
"I'll try to be less obvious about that. But like I said, it's a medical condition." There's a hiss as Leah wets her diaper. "Could I get a change?"
"Oh! Sure!" Tina brings Leah to her bedroom, which now has a changing station, to put her into a fresh diaper.
Before long, the first day of school arrives. Tina drops Leah off at the high school and watches her stepdaughter walk in, wearing a baby diaper under her school uniform.
