She readies herself for the dare

Normally she would not even think twice about being naked in a stall like this, but right now Sophia was trembling with excitement. She would be fully nude in public, which excited her, but she could always quickly retreat back to her stall to put her bikini back on. It was risky, but her backup plan was solid enough that she was brave enough to go for it. If all else failed she could always rush into another empty stall and lay low until everyone had left again, after which she could return to her own stall again.

She untied the bracelet with the key from her wrist and held it in her hands. It had a bright green plastic cover, so she would be able to see it well against the white and blue anti-slip tiles that made up the floor. There were three long rows of stalls, and she found herself in the middle one. Her stall had a door on both sides, so she could enter or leave from either side int. The room itself was had only two exits, one leading to the showers and the pool behind that, and the other leading to the locker room and two larger shared changing rooms.

Now was the time to decide where to toss her key to. She could slide it underneath on of the walls of her stell, which would mean it would end up in another stall somewhere further down the corridor. The other options was to slide it right into the corridor itself, which would have the key end up out in the open.
