The Series third which four sets of mother and sons are just two of us and go for a hot spring trip, and shows Geki shiimaguwaio in a hot-spring hotel. Give vent to the feelings that I usually controlled as soon as I arrived at the hotel, and already have sex, and start! Forget to be Parent and child, and two people who have become a man and woman are left to nobody anymore. The contrast that emotion of the hot spring and intense SEX weave draws you who look into a screen.
