It is implied that one of the main characters has multiple sex partners over the course of the story, although nothing is shown.
A woman and man have sex, although it is shown through close-ups of their faces. Afterwards, the man is shown naked from the side, sitting on the edge of a bed during a short conversation. Then the man and woman lie naked in bed together, we briefly see a split-second glimpse of the woman's breast as she moves her arm, and then only see bare back and shoulders.
Two young women are shown wearing white robes while they shower and we see a medium close-up outline of one of the woman's breasts underneath her robe.
