Michelle notices something

Michelle and Alexa stood in line for the rollercoaster, Alexa standing behind the former as they waited patiently. As the two managed to get to the halfway point, Michelle looked over at Alexa with a smile. Her smile faltered a bit as she saw Alexa looking up nervously at the rollercoaster... Completely unaware that one of the straps of her sundress was loose and exposing her bra underneath.

"Lexi!" Michelle whispered, loud enough to get her friend's attention but quiet enough to not draw attention from anyone else. "Your dress."

"My what?" Alexa asked before looking down. She blushed and let out a small squeak as she adjusted her strap, covering her training bra again. "T-thanks, Shelly. Nobody saw that, right?"

"No one but me." Michelle responded as Alexa let out a sigh of relief. Once she turned back around, she couldn't help but think about something. If she didn't know any better, Michelle could have sworn that Alexa was wearing a training bra. She shrugged, deciding to ask about it later.

Alexa, on the other hand, gulped as she wondered if Michelle had figured out that she was wearing a training bra, blushing at how humiliating that thought would be. Not nearly as humiliating as the thought of Michelle seeing her diaper, but still. She just hoped that her best friend wouldn't bring it up later. And if Michelle did, well... Alexa would probably come up with something later.

Right now though, both Alexa and Michelle had finally reached the gateway of the rollercoaster before the operator lead them to the car in the first row, another operator fastening the two women in.

As the first operator started the ride, no one was even aware that the second operator had accidentally attached the safety harness through the straps of both Alexa's sundress and training bra...
