Name of film – young boy (child) in brothel touching prostitutes breast – “Haciendo el amor” playing

I only know this short Scene:

looks like a young boy is watching a couple making love in a brothel
a young prostitute is pullling him away and on a bed and exposes her breast and let him fondle it. He pulls out phone from his trouser front.
Playing is “Haciendo el amor” by Michael K feat Pauli.

I would like to know what the film is called and what it is about…
