The breakfast is really tasty, but Leah can already tell it will give her some gas. From both ends. She tries to discreetly let out a few small farts as they eat, and is successful.
But then, she farts again, and her eyes widen. It wasn't just a fart. She can feel some mush in her diaper. And now that she's started, she can't stop.
Leah's bowels rumble, kicking into gear, forcing feces out. All Leah can do is sit there as more and more sharts exit her body, depositing more and more poop into her diaper. Finally, a log begins to crown.
"Uh, bathroom!" Leah mumbles. She jumps down to the floor, but when she lands in a squat, she feels herself shift from passively pooping to actively pushing. The log protrudes further. Any attempts at moving fail, as Leah is forced to finish pooping first.
"Yes, you are using the bathroom," Rita comments. "The one around your waist." Leah grunts loudly. "But don't worry, that's what it's for!" Leah's eyes water from the smell. She bends deeper into the squat, trying to speed things along.
After what feels like hours, the log pinches off. Leah straightens. Unused to the load in her diaper, she stumbles back, falling onto her butt and smearing her mess all over.
"Phew!" Rita says. "You need a fresh diaper! Want me to change you?"
