In the latest installment of Sex Reviews, writers discuss the sex scenes in the film Sanctuary

Sanctuary stars Christopher Abbott as Hal, an heir to a hotel fortune.

The movie premiered at the Toronto International Film Festival last year to great reviews.

Rebecca Onion, a Slate senior editor, and Olivia Snow, a professional dominatrix and research fellow at UCLA’s Center for Critical Internet Inquiry.

The boundaries in their relationship are too hazy for comfort, says Snow.

Snow: The only thing unusual about the session in the film was that Hal seemed to be a half-decent writer.

She says Rebecca forces Hal to remain still while she straddles him, tells Hal that she’s ovulating, and commands him to come inside her.

The movie ends with Hal promising to give Rebecca his company and make her CEO.

Snow: "It is wildly unprofessional! Lots of dommes, myself included, have personal submissives, many, if not most, of whom start out as clients. Some clients may become friends, but a client turning into a boyfriend is unusual".
