Rita, it turns out, is very chill and cool, other than the diaper thing. She's also, despite being younger than Tina, much wealthier, as she is a successful model-slash-actress. Leah only needs one look at her expensive house too understand Rita's nervousness over accidents. Not that she's fine with being diapered, of course. Luckily, Leah gets out of her current diaper and into a new one as soon as she arrives.
To Leah's delight, when she's dropped off by Tina, Rita tells her that she got tickets for the nearby very pricey amusement park. It costs so much to get in that Leah's never been to it. The next morning, Leah changes out of her (still clean) diaper into underpants, a pair of shorts, and a cute tank top. She and Rita head for the amusement park in Rita's fancy car.
Leah gets so caught up having fun at the amusement park that she doesn't realize she needs to pee until it's very urgent. She tells Rita while they're in line for a rollercoaster.
"We can go after this ride," Rita says. "I need to go, too." Leah doesn't want to leave the long line to pee only to get back in it at the end, so she agrees, and tries to ignore her screaming bladder. She's barely tall enough to ride it, but eagerly gets in next to Rita.
It only takes one drop for Leah's hold on her bladder to fail. She moans softly as she feels the warm liquid spread through her underwear and pants. Rita doesn't notice until the ride is over. She quickly covers Leah up with her jacket and ushers her away. In a secluded corner of the park, Rita takes stock of the situation.
"We'll get you some new clothes at the gift shop," she says. "You can pick whether you want more teen style or toddler style. And you can also pick what kind of protection you'll wear."
"Protection?" Leah asks.
"Sweetie, you just peed yourself. Until you can spend an entire day dry, I want you constantly wearing protection. At my house, of course, it will still be a diaper. But elsewhere, including here today, you can choose training pants if you think you won't have any messy accidents." Rita pulls out a diaper and pair of training pants, both in Leah's size, and holds them out. "Now, go ahead and choose. The faster we get cleaned up, the faster we can get back to having fun!"
