An older man tells a fifteen-year-old girl that she can have drugs if she 'pays' him. She is seen getting down to his genitals and is heard unzipping his trousers, and very briefly is seen performing unsimulated oral sex. He is heard moaning, and when she pulls away, his erect penis is clearly seen.
Two underage teens are implied to have sex. They are seen in bed naked together, and the boy gets out of bed, briefly revealing his butt, and gets dressed. The girl tells him they can "fuck all night if he wants", and he says that he will return, but doesn't.
A woman agrees to masturbate a man, after refusing to give him oral sex. Nothing is seen (except a shot of the two of them from the waist up and she opens his pants and laughs, making fun of the size of his penis).
A man has off-screen sex with a girl. Moaning and the bed squeaking is heard. Afterwards, they take drugs together and he pays her. He then tells her friend that he knows she is underage, and makes lewd comments.
Strong verbal references to sex. A girl often talks about "eating out" (oral sex), and two boys graphically discuss a pornographic magazine, though it is not shown. Plenty of references to teens having sex.
