Reaching into her backpack, Charlotte decides it would be better to wear her bikini. She unties her shoes, and takes them off followed shortly by her socks. Feeling the wood floor of the watchtower on her bare feet, makes her already feel much more comfortable. She has never been the biggest fan of shoes, and will normally go without them if she knows nothing will hurt her feet.
After taking off her shoes, Charlotte moves on to starting to unbutton her shirt, and revealing her simple pink bra. As she finished undoing the last button, and began to take her shirt off, Charlotte started to feel nervous. Here she was shirtless, in the middle of a national park, where someone could potentially see her. After a quick glace around, and confirming that she was indeed alone, she moved to her shorts, undid the button, and pulled them down revealing her matching pink panties.
Now in only her underwear, she did one more glance around before undoing her bra, and slipping her panties off. Fully naked, she quickly grabbed her bikini bottoms, slipped them on, and tied her top into place. After a few minutes getting comfortable with being in her bikini, she had to admit, that she felt far more comfortable.
Another 10 minutes passed, until she got a call on her radio telling her to do her first round of the park. She knew that would complicate things a bit, but she had to make the round, or she would not be doing her job. She had to decide before going out, would she remain in her bikini, or would she put her uniform back on over her bikini.
