This is a mild adult film. There are at least 10 extended simulated sex scenes showing full nudity - though no male genitalia is shown and during the female nudity there are no "closeups" of the female genitalia.
Lots and lots of breasts scenes with the two female characters.
Simulated Sex is probably 70% of the movie with lots of positions, etc.
All sex is single couple, heterosexual. All the male characters have sex at least once with one of the women and conversely the two woman have multiple partners. Particularly, one woman has sex with all four male characters, the other woman has sex with two of the male characters, and several characters have sex with one partner and then proceed to have sex with another partner shortly afterwards.
