Christmas Pool Party (Image 3 of 8, details in the description)

I've created several images from a modified prompt compliments of @MoniB (Thank you!). But writing stories for all of them will take time and I want to get them posted. So I'm going to start the story and let the audience decide how it ends for each image in this series

They had all been invited to a Christmas Party at their friend's family mansion. The details were kept secret and no one knew till they got there. They were all told to dress causual but smart and be prepared for anything. When they arrived they were all led to the indoor pool area where the party was being held pool side. The pool party Christmas theme included the opportunity to enjoy the pool if they were brave enough to indulge. The only requirement for the pool was you had to enjoy it how you arrived at the party. No changing to go in. Each group took a photo when the arrived. Some were already flirting with being in the pool others were on the edge. You decide which groups are brave enough in the comments.
