(chapter originally by ? at writing.com)

Isabel decided to stay sunbathing, and quickly falls asleep, but, suddenly, she's wake up by a familiar voice: Melissa!!!!

"Wake up, little nudist." Melissa said

Isabel doesn't understand why she said that, but when she looks down, she understands it: she was totally naked and tied to a palm tree!!! She knows that Melissa had taken her strapless bikini.

"Give my strapless bikini back." Melissa. Isabel said.

"Come and take it." Melissa said before escaping

Isabel frees herself from the ties, but she doesn't know what to do: chase Melissa naked or find something to cover up first?
