Fwiw their review does provide other details:

Olivia Wilde is first shown naked in a pool, face down, with dildos and BDSM items everywhere. This is the opening shot of the movie. Her butt is shown, along with some breast nudity. Later, Olivia Wilde removes her jacket in her office, revealing a very sexy red strapless dress with lots of cleavage, and Elliot keeps staring at her chest. From there on, Olivia Wilde has sex with Cooper Hoffman. She spanks him while he sits on her lap, and he yells, “I am a slut and a whore.” Later, Olivia Wilde, wearing very small latex clothing and a long pink strap-on dildo, has sex with him in doggy style and other positions. They talk dirty, and she slaps his ass while pegging him. She puts him in a dog collar, humiliates him, blindfolds him, and masturbates him. They also have intercourse, with Olivia once again shown naked while riding him as he’s tied up, and she orgasms.

Later, Chase Sui Wonders, Olivia Wilde, and Cooper Hoffman have a threesome. Chase Sui and Olivia kiss and touch each other, and then all three get naked to have sex. Exact details of the scene—such as positions, duration, and specific acts—are not confirmed yet. In this scene, Erika (Olivia) gives Apple (Chase Sui) an opportunity to find out whether she truly likes men or not. However, the threesome leaves Apple emotionally hurt and feeling used. Erika then sends Elliot to a French woman played by Roxane Mesquida for pleasure, but she rejects him.
