Carolyn Grace has an older husband who insists she wear very old-fashioned night clothes and is obviously unexciting in bed. She has lots of fantasies, triggered by chance events and encounters.
Cheating Notes
The description says that all the wife's sex with different people (and groups) are just her fantasies, but they seem very real (and very hot) to me as there are no dreamy-like transitions that indicate that the wife just dreamt or fantasized any lovemaking of hers that just happened.
Ok, maybe some of them do, like the transition in the black waiter scene (it's even a different woman, not her, whom the black water is fucking in that scene). But some really don't have dreamy-like transitions at all and may really have happened for real, like when she visits a mature old woman, who in turn calls a mature old man to come and fuck her.
Maybe that's the point of the film, to make us guess what scenes happened in fantasy and what scenes happened for real.
A porn masterpiece indeed!…English subtitles needed.
