In the first story, several women gather around and perform a ritual. Two of them are topless, and the scene goes on for maybe two minutes or so. Not much focus is put onto the women's breasts, however. Later they perform another ritual and are all completely clothed except for one girl who has black tape over her nipples. One woman places tip for bellhop in her cleavage; he sheepishly walks over and removes it.
One of the women from the ritual is scorned because she admits to swallowing a man's semen. The sperm was an ingredient needed for their ritual, and the woman is given one hour to collect more. A little bit later she meets a man who is reluctant at first to have sex with her, but then later obliges. They are shown passionately kissing and she removes her top and reveals her breasts, but then nothing after that.
A man walks into a room and is accused by another man of sleeping with his wife. It's eventually implied that the whole thing is a sex game. The second man kisses the original man and then tries to persuade him to have sex with his wife; there is an implication he might have had sex with a man and be bisexual. No actual sex or nudity, just sexual dialogue. At one point, the woman is bragging about the size of the first man's penis to her husband (she is lying, as they had never met before), and she uses many, many terms to refer to his genitals..
A man and his wife passionately kiss a few times. When they are gone, their young child is shown watching a pole dancer on TV (no nudity).
Two naked women run out of the Penthouse, with their butts briefly exposed. They are only onscreen for several seconds. Later there is some sexual dialogue, though nothing too explicit.
