Her panties

Jenna was flying face-first down the slide with her panties around her ankles when they got caught. There was nothing she could do as she went flying straight out of them at the speed of light. She gasped as she felt the cold plastic of the slide rubbing against her almost-naked body as she kept moving down the slide, her inner tube somewhere far ahead of her.

A few seconds later, she reached the end of the slide. Sara looked on in shock as her friend went flying through the air with her bra around her waist, her pale, nude body of full display before she belly-flopped into the water. Thinking quickly, she passed Jenna an inner tube, which she gratefully slid inside of before pulling her bra back up. If she was careful and stayed inside the tube, no one would know that she was naked from the waist down. Nonetheless, she felt very, very exposed as the cool water flowed, unobstructed, across her naked lower half.

Sara tried to make light of the situation to cheer her up. "Hey, your body could really use the extra sun," she said with a giggle. "Especially right here!" she said, squeezing Jenna's butt and making her yelp. "When we're done swimming, maybe you could try tanning in that outfit with me!" She gave Jenna a wink.

Jenna blushed, picturing herself tanning naked on the crowded deck nearby. That was definitely not what she had in mind when she set out for the amusement park!

"Okay, okay," said Sara. "Maybe that isn't such a great idea. But seriously, what do you want to do? I mean, it might be hard to get back to the locker room wearing only a bra! And you really aren't that exposed right now... should we hang out here until it gets less crowded?"

Just then, Eric came flying down the slide and swam over next to them, totally unaware of Jenna's wardrobe malfunction.
