Sarah sees drawings of nude men. She quietly walks up to David who is sleeping. Her butt is to the camera as she walks. She lifts up the blanket to look at his penis (her reaction is seen by the viewer) and her breast is visible. She then walks back to bed and her hair is covering her breasts.
David and Sarah begin to have sex. They begin to kiss each others hands and kiss. They lie down with David on her. Her breasts are clearly shown when she is on top of him, his hands touching her nipples and her breasts and most dissolving shots show them touching each other everywhere as the scene stops with a kiss. The entire scene lasts about two minutes. However the breasts and face are never seen at the same time. Body doubles were used for some shots.
