"It was me!" Leah wails. "I'm- I'm so gross and- and stinky! I filled my diaper like a baby, I'm- I'm just a poopy pants baby!"
"No, sweetie, you aren't!" Rita says soothingly. She picks Leah up, somehow not reacting to the stench from the teen's filled diaper, and rests her against her shoulder. Leah continues to sob as Rita gently rubs her back. "I expected this when I agreed to watch a teenager. This is normal."
But Leah knows it's not normal. She doesn't say so, however, merely whimpering as she pees without warning. Following the urine is another load of poop. Leah grunts as she pushes out multiple small logs and mush.
"Let's get you in a fresh diaper and back to bed," Rita says, once the second round of poop and farts tapers off. Leah finds herself sucking on her thumb for comfort as Rita brings her to the changing station in Leah's room. The second Rita opens Leah's diaper, she winces.
"I know, it's bad," Leah mumbles around her thumb.
"You clearly are something that didn't sit right with you." Rita wipes Leah down and puts her in a fresh diaper. "I bet you have a sensitive stomach. Don't worry, I'll start feeding you stuff that won't be as rough on your delicate tummy."
Rita tucks Leah into bed. After a few minutes of sniffling, Leah finally falls asleep. She wakes up in the morning to another full diaper. A full diaper she doesn't feel she could change without making a huge mess.
Leah waddles into the kitchen. Rita is putting the finishing touches on breakfast, and looks over to see Leah.
"I need a change," Leah says.
"Oh, okay! Why don't you use your diaper really quick while I finish up here, then I can change you."
"...okay." Leah bends into a squat and pees. There's an ominous rumble before a thick log slowly begins to exit into her diaper. As Leah pushes, grunting, she looks at what Rita has prepared for her "sensitive stomach".
