Real SEX, serious SEX—hot spring trip with another man's wife. Freed from daily life, the man and the married woman bare their dark desires, acting on instinct like beasts, indulging in pleasure day and night, over and over! Because of the limited time of one night and two days, they forget reality, and the beautiful wife returns to being a 'woman'. 'After all, it feels better without a condom,' she deliberately chooses her 'safe days' to plan a 'bareback' trip.
