There is a hint of lewdness behind the phrase "family get-togethers." There is a family where the mother uses her body to teach her two daughters how to please a man, a family where the sister with a sexy body teases her brother but gets serious, and a family where the father thrusts his thick dick into her right in front of the mother. The scene where the three families meet in the open-air bath and mix together is a hot spring paradise!
