A treasure chest!

It looked like an old treasure chest!

"That's odd... how would nobody see this?" Mackenzie said. She reached under water and gave the lid a curious tug. It opened with ease, much to her delight. Maybe there was a whole bunch of gold in the chest! That could pay for her whole vacation!

Alas, the chest may not have been as unnoticed as Mackenzie thought. After lifting the lid, she found it to be completely empty.

"Well so much for that." The naked red head said, looking disappointed. She was about to swim away, slightly hindered with the swimsuit she was still holding, when she paused. While the chest didn't give her riches, it did give her a spot to put her swimsuit.

Mackenzie felt a tickle in her stomach, and looked around again. While there were lots of swimmers, they weren't near her. So far she had been safe with getting fully naked. Having the swimsuit in her hands was a bother, and now she had a place to put it. However, that did cut her off from easy access to her swimsuit.
