A man's wife is having an affair with another man. They are in bed together (no sex) when the husband comes to the house. He throws a baseball through the window and she jumps out of bed. You get a brief glimpse of her nightgown pulled up and a partial glimpse of her buttocks and underwear.
A man and a woman kiss somewhat passionately on the front porch - he tries to come into her house to have sex, and she repeats "next time" several times and goes into the house without him.
