Family Affair (1982)

...THEY COULDN'T GET ANY CLOSER THAN THAT

Kevin, an unhappily married man, retreats into a fantasy world of sex with a young blond man. He also imagines his office boy, played by Jake Stryker, masturbating among the law books. The film is highlighted by beautiful close-ups of a cock-worshipper performing loving fellatio on a big dick that is shaped like the SST.
