She realized her nudity [End]

Olivia has blocked out most of the sound around her with her headphones, but just cant get comfortable enough to sleep. Eventually she notices people looking at her and occasionally taking photos. Olivia removes her headphones to ask what's going on, and as she does she hears two guys discussing her tits, causing her to look down and realize, she screamed until her friends reluctantly got her some spare clothes from their carry-ons.

They go on to have a nice trip, though Olivia stays mad at her friends for letting her be humiliated like that. They, on the other hand, keep plans in mind for how to try it again one day.
