"Once Upon a Time ... in Hollywood" (2019): Teen Pussycat Offers Oral Sex

Here's IMDb's plot summary for Once Upon a Time ... in Hollywood (2019):

A faded television actor [Rick Dalton (Leonardo DiCaprio)] and his stunt double [Cliff Booth (Brad Pitt)] strive to achieve fame and success in the film industry during the final years of Hollywood's Golden Age in 1969 Los Angeles.

Google elaborates in its plot summary by adding:

Rick also happens to live next door to Roman Polanski and Sharon Tate -- the filmmaker and budding actress whose futures will forever be altered by members of the Manson Family.

In one scene, Cliff gives Pussycat (Margaret Qualley), a teen member of the Manson Family, a ride to the Spahn Ranch. Here's the dialogue:

Pussycat : Want me to suck your cock while driving?

Cliff Booth : [thinks for a bit] How old are you?

Pussycat : What?

Cliff Booth : How old are you?

Pussycat : Wow, man. First time anybody asked that in a long time.

Cliff Booth : What's the answer?

Pussycat : Okay, we gonna play kiddie games? Eighteen. Feel better?

Cliff Booth : You got some I.D., you know, like, a driver's license or something?

Pussycat : [laughing] Are you joking?

Cliff Booth : No, I'm not. I need to see something official that verifies that you're eighteen, which you don't have because you're not.\

Subsequently, Pussycat informs Cliff: Obviously, I'm too young to fuck you. But obviously, you are too old to fuck me. 

This reminds us of the memoir Member of the Family: My Story of Charles Manson, Life Inside the Cult, and the Darkness that Ended the Sixties where Dianne Lake, who became one of Charles Manson's girls at the age of 14, shared: For the first time, I came to see that my sexuality was empowering---something I had that older men seemed to want [...] In my mind, sex with older men meant I was a woman [...]

Interestingly, in this advertisement for the film that was posted on Margaret Qualley's Instagram account, Pussycat is reduced to Cat but, although Qualley was 24 when the film was filmed, she's clearly made to look like a nymphet.
