Old & Young theme

[Bad Samaritan]

Can anyone recommend a good film with the old man - young girl theme? No sleazy gonzo, no blowjob-only, and no Robert Leray. I think the old-young thing adds a certain realism because most of the guys these girls have sex with in real life are not way younger than the porn "grandpas". To add, the plot should also have been rendered well. So, no lollipops, no 30 y.o. seasoned porn actresses with pigtails and fake freckles. Thanks in advance.
