"...the set of my latest film!" Rita says cheerfully. "Your mommy told you I'm an actress, right?"
"Y-yes," Leah mumbles as another fart escapes from her. She's too miserable to correct Rita about her relationship with Tina.
"I have to pick up a script rewrite really quick. Then we can go home."
Thankfully, the drive to the set doesn't take long. But Leah has stunk up the car enough that Rita rolls the windows down and leaves them down when she exits the car. She carries Leah into the building with her, propped on one hip.
Leah is momentarily distracted from her loud digestive system by the awe of being in a place where movies are made. She looks around, starstruck by the various workers bustling around. Rita walks right up to a man standing by a large camera.
"Ah, Rita!" he said when he sees her. He pulls a script out of the messenger bag he's wearing and hands it to her. "Here's the new script."
"Thanks, Joel."
"And who's this cute little girl?" Joel asks, noticing Leah.
"My niece. She's turning three soon."
"She's adorable!" Joel gushes. Leah abruptly lets out an enormous fart. Some poop accompanies it, kick-starting the process of Leah messing herself again. She tries to hold it back, but more exits. Rita pats her butt and feels the poop squishing.
"Oh! Are you making boom-boom?" Rita asks. Blushing, Leah nods silently. "Here, finish up while I talk to Joel."
Rita sets Leah on the ground. Leah turns all her focus to finishing her humiliation as quickly as possible. The surrounding set and its noises fade away as she pushes. She grunts loudly, her face now red from embarrassment and effort, as small logs enter her diaper. Leah bends into a deeper squat for the grand finale. There's a loud fart as a massive amount of mush rockets into her diaper. Without thinking about it, Leah pees as well, then straightens. Her diaper sags under her and smells.
Leah tugs on Rita's pant leg. Rita looks down.
"All done?" she asks. Leah nods. "Good! I'll get you changed. And thanks, Joel, we'll take you up on that offer!"
"My pleasure," Joel says. He smiles at Leah. "I can't wait to see you again!"
Rita picks up Leah and brings her into a bathroom. Leah resigns herself to the diaper change, trying not to squirm or risk spreading her mess everywhere.
"Joel is the director," Rita says as she removes Leah's diaper. "He was very impressed by your cuteness and the fact you're comfortable using a diaper despite being almost three."
"I not thwee."
"No, I know, you're only two! But you'll be three soon!" Rita says. Leah scowls. Why did her aunt have to be a method actor? "Anyways, there was a role for a little pamper packer, but the family had to back out unexpectedly." Dread builds in Leah's gut. She has a feeling she knows where this is going. "Joel wanted to offer the role to you, without even needing to audition! I texted your mommy while I was talking to Joel, and she agreed that you could be a little toddler actress!"
"I don't wanna."
"Hmm. I don't know if you have a choice. Little girls your age have to do what their guardians want," Rita says. She finishes changing Leah's diaper. "All done!"
Leah pouts at her. Rita pinches her cheek.
"Aw, cheer up! You're going to appear in..."
