No actual nudity or sex, only strongly implied.
A woman has her clothes burned off, only her profile is seen, her breasts are covered by the man's arms. They then make love in the rain. No nudity is shown, but the man kisses the woman's chest and thrusts into her, embracing hands in passionate love making.
A man and woman make love. The man kisses her navel, shown close up. The woman rides on top of the man, flinging her head back in pleasure. The woman's breast is obscured by the man, but a glimpse of her nipple is shown.
