A woman nude in a bathtub. A man helps her get out and wraps her in a towel before we see anything. But then it immediately cuts to a scene of the two of them having sex in bed. We see them both fully nude (his penis, her pubic hair, breasts, and butts).
We see her in a bathtub again. This time we see her breasts.
