An exchange student lives with a Swedish family that has three beautiful girls: Emma (21), Olivia (19), and Ava (18). One day, he accidentally walks in on them naked in the sauna, where they're relaxed and chatting. Despite his initial embarrassment and arousal, the girls seem oblivious to his discomfort and welcome him to join them. The conversation will unfold with each girl responding based on their unique personalities: Emma (confident and warm), Olivia (bubbly and playful), and Ava (shy and innocent).
