Colin Howell, a respectable dentist and pillar of the community, begins an affair with Sunday school teacher Hazel Buchanan. They soon conspire to murder their spouses.
09:20 - The dentist caresses the wife's leg under the water in a public pool. He tells her, "I'm not having innocent thoughts about you, Hazel." She responds positively with, "Maybe I'm not so innocent myself."
13:54 - The wife and the dentist's first tryst. Initial kissing and after-sex dialog only. Her side boob might have been shown but the scene is quite dark.
The pastor finds out about their affair. Their spouses are informed, they talk, apologies and acts of forgiving are given, etc. After all that, the wife and the dentist continue on with their affair.
4:54 - The wife and the dentist fuck in the car. Only the initial part is shown, where she climbs on top of him. Non-nude.
09:58 - The wife and the dentist fuck in the bedroom. This time, we see some hip thrusting and humping action and we also see her side boob and tit briefly, but mostly the camera is too close to their bodies.
21:17 -We see the wife's boobs here just before the dentist fucks her after sedating her. We don't see the sex.
