Gift shop

Dana decides that she doesn't want her mistake to mess up the day for all her friends, so she decides going to the gift shop and hoping they have a swimsuit is the best idea. So she walks her naked ass past the admission booth and even stupidly removes her hand from her boobs to show her membership wristband, even though it's the only thing she's wearing so it's obvious she has one. This exposes her boobs to the attendant and the park guests who were already staring at her because she's walking around in public covered only by her hands. Luckily, it's not busy yet so only a handful of guests saw her.

They walk toward the gift shop and Dana has to be reminded to cover her chest again. She freaks out and moves both arms over her chest so now her audience is seeing her bare crotch. And her friends tell her to cover that too. Thankfully, they are soon inside the shop. While her friends tell the shop owner about the situation they are in, Dana is looking around for swimsuits. She finds one and grabs it. She brings it up to the register, forgetting to cover anything and giving the shop owner a wonderful view of everything she has.

Unfortunately, the swimsuit is expensive. The markup is insane. Her friends brought only enough money for some snacks. They're way short on funds.
